PLANNING COMMISSION STAFF REPORT
DATE: September 11, 2024 PUBLIC HEARING
SUBJECT: CITY OF PALM SPRINGS FOR A LIMITED UPDATE TO THE GENERAL
PLAN, INCLUDING REVISIONS TO THE LAND USE ELEMENT,
CIRCULATION ELEMENT, SAFETY ELEMENT AND ADMINISTRATION
SECTION.
FROM: Department of Planning Services
SUMMARY:
The purpose of this public hearing item is to consider the limited update to the General
Plan (the “Update” and “2040 General Plan”). The Update began in 2019 and involved
new Vision and Priority Statements, and revisions to the Land Use, Circulation, Housing
and Safety elements. The Housing Element was adopted in September 2024, and the
purpose of this review is to consider the remaining revisions which comprise of the 2040
General Plan.
RECOMMENDATION:
1. Open the public hearing and receive public testimony,
2. Adopt the draft resolution included as Attachment A and entitled, “A RESOLUTION
OF THE PLANNING COMMISSION OF THE CITY OF PALM SPRINGS,
CALIFORNIA, RECOMMENDING THAT THE CITY COUNCIL (1) APPROVE AN
ADDENDUM TO THE PREVIOUSLY CERTIFIED ENVIRONMENTAL IMPACT
REPORT TO THE 2007 GENERAL PLAN FOR AN AMENDMENT TO THE LAND
USE, CIRCULATION AND SAFETY ELEMENTS AND (2) ADOPT THE 2040
GENERAL PLAN WITH AMENDMENTS TO THE ADMINISTRATION SECTION,
LAND USE ELEMENT, CIRCULATION ELEMENT AND SAFETY ELEMENT.”
BACKGROUND:
General Plan Requirements
California law requires each city and county to adopt a comprehensive, long-term general
plan to guide its physical development. California Government Code, Section 65302,
requires that general plans include the following elements: land use, circulation, housing,
conservation, open space, noise, safety, and environmental justice. The State Office of
Planning and Research (OPR) recommends updating a general plan every 10-15 years

Limited General Plan Update
to reflect changes in community values, economic conditions, and emerging issues and
challenges.
2007 General Plan
The City’s current General Plan was comprehensively updated in 2007, and the Housing
Element has been updated to comply with state law and housing planning cycles since
that time. The General Plan consisted of an Administration Section and the following
elements: Land Use; Housing; Circulation; Recreation, Open Space, and Conservation;
Safety; Air Quality; Noise; and Community Design. The document also incorporated
appendices, including a Downtown Urban Design Plan, among others.
2040 General Plan
In late 2019, the City approved a contract with Placeworks, Inc. (“Consultant”) to assist
the City with a limited update to its General Plan and ensure the Update reflects current
conditions and values of the community, complies with state housing laws, and addresses
revision recommendations of the Ad-hoc Planned Development District (PDD) Committee
on removing or revising PDD requirements. Due to budget limitations, the Update was
focused in scope on four chapters of the General Plan that were most in need of revision:
the Land Use Element, Circulation Element, Housing Element and Safety Element. Minor
updates to the remainder of the document, including the Vision & Priority statements,
were also proposed as part of the Update.
ANALYSIS:
A city’s general plan serves as the guiding policy document for achieving the community’s
vision for the future and contains goals, policies and actions for realizing this vision. The
Update – or 2040 General Plan – has been an iterative process with each phase building
on subsequent updates and includes input from community members and direction from
the General Plan Steering Committee (GPSC), Planning Commission and City Council.
Throughout the process, community engagement and input guided City staff and the
Consultant in drafting the overarching Vision and Priority Statements and policies and
programs in the updated elements.
Administration Section/Vision & Priorities
Early in the Update process, the Vision & Priority statements were revised to establish
the overarching principles that shaped updates to the 2040 General Plan. Outreach and
direction on these statements was sought from respondents to a community surveys,
several stakeholder groups, the GPSC, and the Planning Commission and City Council.
The City Council considered these statements on October 8, 2020 and March 10, 2022,
directing staff and the consultant to make further revisions after conducting additional
outreach. On April 7, 2022, the City Council accepted the draft Vision and Priority
statements which have been incorporated into a revised Administration Section,
Attachment B to this report.

September 11, 2024 -- Page 3 of 8
Limited General Plan Update
The Administration section has been further updated to describe the 2040 General Plan.
Revisions include the groups and methods used to shape the Update, including the
General Plan Steering Committee, public outreach, community workshops, listening
sessions, and digital engagement. The introduction on Planned Development Districts
(PDD) was revised to describe changes to PDD regulations. The Administration section
describes the new format of the Land Use, Circulation and Safety Elements, with
separating the Implementation Actions from the content of each element. Finally, other
minor changes were made to reflect current conditions, such as the removal of the
text/graphics describing redevelopment areas, potential sphere of influence areas, etc.
Land Use Element
The Land Use Plan provides the overall fabric of land uses for each parcel of land
throughout the City, including a variety of residential, commercial, mixed use and
industrial uses, as well as open space and special policy areas. This Update involves
changes to both the Land Use descriptions and the Land Use Plan, which are part of the
Land Use Element and include some necessary changes to accommodate additional
density to meet the Regional Housing Needs Assessment (RHNA) allocation for the
Housing Element. Other changes were to address reforms to the Planned Development
District (PDD) process, zoning inconsistencies, encourage affordable housing, and
necessary administrative updates. Below is a discussion of the proposed updates and
changes to these portions of the Land Use Element.
• Land Use Descriptions: The proposed land use descriptions are consistent with
the descriptions presented at the Council meetings of July 26, 2021 and April 7,
2022, and include the following updates and revisions:
o Remove requirement to process a Planned Development District, as was
required in some land use descriptions in the 2007 General Plan
o Incentivize projects providing 20%1 of the units towards meeting the City’s
affordable housing goals in the “Mixed Use” and “Central Business District”
designations
o Remove hotel intensity standard and identify hotel uses as permitted in
various designations
o Update desired mix of uses in the “Mixed Use” designation to reflect current
conditions and preferred outcomes of future uses in these areas
• Land Use Plan: The Land Use Plan, Exhibits 2-2 and 2-3, shows all uses
throughout the City and limits the maximum residential density and/or commercial
or industrial intensity (represented as Floor Area Ratio) of each property in Palm
Springs. As noted previously, significant changes are not proposed from the 2007
Land Use Plan; rather, minor changes are proposed to address the RHNA
allocation and other administrative updates. An increase in density is proposed to
address the RHNA allocation at the southeast corner of North Palm Canyon Dr
1 Since presenting the land plan in 2021 and 2022, staff reduced this threshold from 50% to 20% (and
removed a minimum unit count), due to the higher percentage appearing too onerous or realistically
achievable in practice.

Limited General Plan Update
and Via Olivera, where roughly 5.5-acres of land is proposed for redesignation
from “Mixed Use” to “High Density Residential.” The Land Plan includes other
administrative changes as follows:
o Refine boundaries and alignments for consistency with natural features,
zoning, and updated parcel boundaries
o Reflect changes to right of way and vacated streets (remove ROW
designations and vacated streets at the airport; make consistent with
“Airport” and “Industrial” designations)
o Change land use to more accurately reflect what has been built (e.g. density
adjustment)
o Implement changes to be consistent with adopted Section 14 Specific Plan
On July 26, 2021 and April 7, 2022, the Council considered other changes to
various properties, based on community input and property owner requests,
including the re-designation of the following property:
o Desert Highland Neighborhood. Requests were received to redesignate
parcels along (1) the east side of El Dorado Blvd between Tramview Road
and Rosa Parks Road to “Medium Density Residential” and (2) the west
side of Indian Canyon between Tramview Road and Corozon Avenue to
“Mixed Use”. These are incorporated into the Land Plan.
o Former COD Site. The land plan was initially proposed to redesignate this
126-acre area to residential and mixed use, but Council directed that this
parcel remain “School” and go through a separate process to determine the
new land uses for the site.
o Various Open Spaces. Several comment letters requested the city re-
designate the Boulders and Crescendo sites within the Little Tuscany
neighborhood and the Palm Hills area south of the Rimrock (Vons)
Shopping Center, to “Open Space.” However, due to state housing laws
requiring a no net loss in density, the parcels remain unchanged from the
2007 land plan.
• Goals, Policies and Implementation Programs: In addition to responding to
updated Vision and Priority Statements, the goals and policies have been revised
to reflect community feedback, current trends and practices, and important issues
that have been raised during the review process by the GPSC, Planning
Commission and City Council. The Implementation Programs were removed from
the document and included as separate matrix that accompanies the Land Use
Element as an attachment.
The land use descriptions and plan described above were previously considered by
Planning Commission and City Council, due to the implications on the other components
of the Update including circulation network and the California Environmental Quality Act
(CEQA). On April 7, 2022, the Council considered the land use descriptions and land
plan, as well as the assumptions for the projected buildout, and generally found that the
proposed changes and assumptions on buildout were acceptable. This was important
early in the process as it informs assumptions on the City’s circulation network and ability
to accommodate future growth, which would influence revisions in the Circulation
Planning Commission Staff Report
September 11, 2024 -- Page 5 of 8
Limited General Plan Update
Element, if necessary. However, because the proposed overall revisions were minor,
there was more flexibility in making adjustments to the circulation network as described
in the Circulation Element changes below.
With the land use descriptions, plan and projected buildout in place, the goals, policies
and implementation programs were subsequently updated. On May 18, 2023, the General
Plan Steering Committee reviewed the draft Land Use Element and provided feedback
which has been incorporated.
Circulation Element
The draft Circulation Element, which identifies existing and future transportation network
needs, includes updates to address topics related to safety, parking and transit. During
the public outreach process, there were several comments on these topics and requests
for traffic calming, pedestrian and bicycle path improvements, and other relevant issues,
such as increasing parking supply, improving road surfaces and street signage, and
expanding regional transit connections. However, the overall revisions were a refresh of
the 2007 Circulation Element, rather than an overhaul or comprehensive update. Below
are changes that occurred:
• Simplified Level of Service narrative and added Vehicle Miles Traveled as a metric
to be considered, in accordance with state law
• Other related plan references, such as the Active Transportation Plan and CV Link,
were added, updated and/or revised to reflect necessary changes since 2007
• Exhibits were revised:
o Circulation Plan, Figure 4-1, revised to reflect current conditions of the
roadway network, including changes to reflect road reconfigurations (such
as “road diets”)
o Roadway Sections, Figure 4-2, changed to reflect new and existing right-of-
way sections with modern graphics
o Bikeway and Trails Plan, Figure 4-4, updated to show bike and trail
pathways, as well as CV Link
• Goals and policies were updated with an emphasis on complete streets and safety,
and Implementation Actions were removed for inclusion as a separate matrix
attached to the Circulation Element for easy tracking
On March 21, 2024, the General Plan Steering Committee reviewed the draft Circulation
Element and provided feedback on the proposed revisions, including goals, policies and
programs. Based on the Committee’s feedback, additional revisions were incorporated.
Safety Element
The Safety Element evaluates potential hazards and risks in Palm Springs related to
seismic activity, flooding, wildfire, hazardous materials, and climate change, and was
prepared to address several state laws requiring jurisdictions to consider climate change
issues. Prior to the preparation of the draft Safety Element, a Vulnerability Assessment
Planning Commission Staff Report
September 11, 2024 -- Page 6 of 8
Limited General Plan Update
was prepared to assess climate change vulnerability and address climate change
adaptation and resilience, in conformance with requirements in California Government
Code Section 65302(g). This Assessment evaluated impacts to populations, built systems
and services, economic assets, and ecosystems and natural resources, and ultimately
identified several opportunities to integrate adaptation measures into the Update that will
help the community prepare for, respond to, and recover from climate change hazards.
In early 2022, the Vulnerability Assessment was reviewed with a subcommittee of the
Sustainability Commission, which provided feedback before the Assessment was
finalized.
With the Vulnerability Assessment complete, the draft Safety Element was updated to
reflect current conditions and other necessary revisions required under state law. The
draft includes discussion and goals and policies on many of the previous Safety Element
topics, but also a couple of new sections:
• Disaster preparedness, response, and recovery
• Seismic hazards
• Geologic hazards
• Flood and dam inundation hazards
• Urban fire and wildfire hazards
• Hazardous materials and waste
• Airport safety
• Police and Fire services
• Climate change resilience (new)
• Multiple natural hazards (new)
The draft Safety Element was reviewed by the Sustainability Commission on September
20, 2022, to provide feedback before the draft was finalized. In accordance with State
law, the draft Safety Element was reviewed by the California Board of Fire and Forestry,
which provided favorable comments and found the draft in compliance with State law.
Public Participation
There have been several opportunities to engage with the community and receive input
from the public. The following list summarizes the public engagement and participation
opportunities that have been part of the process to update the General Plan:
• General Plan Steering Committee. The General Plan Steering Committee
(GPSC) was an ad hoc committee established to serve as one of the primary
channels for engagement related to the Update. The GPSC consisted of nine
community residents and representatives, including one resident from each
Council District, the Planning Commission Chair, a Sustainability Commissioner, a
ONE-PS representative, and the Agua Caliente Band of Cahuilla Indians’ Planning
Director. The Committee met on eight occasions and provided direction on the
overall vision and priority statements; the draft land use definitions and policies,
proposed land use map, and resulting buildout; the draft housing plan and
proposed approach to address Regional Housing Needs Allocation (RHNA); and

Limited General Plan Update
the draft Circulation Element.
• Community Workshops. City staff hosted two community-wide workshops at the
Palm Springs Convention Center. The first workshop occurred on February 24,
2020 and involved a presentation on the Update, workstations for attendees to
provide feedback on topics related to housing, land use, and circulation, and
computer stations to complete a survey. On July 13, 2021, the second workshop
included an overview of the city’s approach to addressing its RHNA allocation and
introduced the land use plan.
• Neighborhood Listening Sessions. In June 2021, City staff invited community
members to four listening sessions in targeted areas of the City to understand
challenges area residents face finding, getting access to, attaining or staying in
safe and sanitary housing, gaining access to physical activities, foods, public
facilities and community services and reducing pollution exposure. These
sessions were held at the Demuth Community Center, James O. Jesse Unity
Center, Mizell Center, and Vista Del Monte Elementary School. The session held
at Vista Del Monte Elementary was conducted with Spanish translation.
• Online Posting. The draft changes to the General Plan were posted online for
public review prior to consideration by the General Plan Steering Committee and
Planning Commission.
• Surveys. The City administered three surveys related to the Update. The first
survey sought feedback on the Vision & Priority statements. The second survey
was an interactive online exercise requesting participants map community assets
and identify areas for improvement. The second survey also requested feedback
on some emerging themes related to land use, mobility, housing, and open space
that came out of the first community-wide workshop and prior survey. The third
survey was conducted as part of the neighborhood listening sessions to
understand participants thoughts on housing, parks, public facilities, healthy food,
medical care, and transit. The responses to these surveys informed the proposed
goals, policies, and programs.
• Public Meetings. In addition to the General Pan Steering Committee meetings
and neighborhood listening sessions, the draft Update is being considered by the
Planning Commission and City Council at public hearings prior to adoption.
Comprehensive Zoning Code Update
A comprehensive update to the Zoning Code is underway which will implement the 2040
General Plan and associated changes. It is also anticipated that further amendments to
the General Plan may be required upon completion of the Zoning Code update to ensure
consistency between the two documents. That determination will be made as the Zoning
Code process proceeds and based on the final version adopted by the City Council, which
is anticipated in late-2025 or early 2026.
ENVIRONMENTAL ASSESSMENT:
Any update to the City's General Plan is subject to the requirements of the California
Planning Commission Staff Report
September 11, 2024 -- Page 8 of 8
Limited General Plan Update
Environmental Quality Act (CEQA). The City prepared an Environmental Impact Report
(EIR), State Clearinghouse No. 2006071060, for the comprehensive update to the
General Plan in 2007 (2007 General Plan). On October 24, 2007, the City Council certified
that the Final EIR, which included a Draft EIR, comments and responses thereto, and
related technical appendices, for the 2007 General Plan in accordance with CEQA.
The City, as Lead Agency, has determined that the draft Update is a Project subject to
CEQA (Public Resources Code [PRC] Sections 21000 et seq.; California Code of
Regulations, Title 14, Sections 15000 et seq.). The City analyzed Project impacts with the
General Plan EIR and it was determined that the proposed Update would not result in any
new significant environmental impacts or a substantial increase in the severity of a
previously identified significant impact. An Addendum to the 2007 General Plan EIR was
prepared to document this conclusion. No further environmental review is required.
(Public Resources Code§ 21166; CEQA Guidelines§§ 15162, 15164.) The EIR
Addendum is included as Attachment G.

1. ADMINISTRATION
PREFACE Our City is unlike any other—we have a reputation as a world class desert resort and we are one of the nation’s most recognized winter playgrounds. We are proud of the timeless character of our Downtown, our celebrated history with the Hollywood entertainment community, our relaxed desert lifestyle, our distinctive collection of architecture, and our idyllic location at the foothills of a picturesque mountain setting. Palm Springs’ eclectic nature creates a desirable environment for a variety of lifestyles. Artists, retirees, professionals, singles, new families, and permanent and seasonal residents all call Palm Springs home. As part of this General Plan, we are embarking on many positive changes for the City’s future. Embracing the positive energy and active involvement of our citizens, the City will continue to take the necessary steps to improve our community and to achieve our vision. As Riverside County’s population continues to grow, it will be imperative for Palm Springs to develop strategies to sustain the vitality and unique charm of the City while managing the imminent growth of our City’s population. We will:
Achieve a quality of life and delicate balance of land uses that make Palm Springs a desirable place to live.
Position the City to attract businesses that stimulate the City’s economy.
Page 1-2 Palm Springs 2040 General Plan
Provide recreational and resort opportunities that will strengthen the City’s reputation as a premier desert retreat. This chapter provides a broad overview of the General Plan—how it was created, what it is to achieve, and how it should be used. It also provides background information such as the Vision, project setting, overview of public outreach efforts, and features of the General Plan—all of which are needed to understand our City’s history and to chart the course for our future. The thrust of this document is to create a mechanism that will preserve the quality of life, character, and image that are distinctively Palm Springs while developing a balance of land uses that encourages sustainability and vitality for our community. In doing so, we will create an enduring legacy of a City that will be enjoyed by generations to come.
PALM SPRINGS VISION Our vision statement serves as the foundation for all of the goals and policies contained within this document. It is with this vision that our City can continue to achieve its maximum potential. The vision serves as the “common ground” from which all decisions are made, and it identifies priority areas where resources should be focused to ensure that our city continues to be a great place to live, work, and recreate.
The Palm Springs Vision
Palm Springs is a vibrant, diverse, and inclusive desert community where year-round and seasonal residents and visitors have enjoyable experiences featuring safe neighborhoods, diverse commercial, arts, entertainment, and cultural opportunities, and an exciting social environment.
The City values its architectural, historical, cultural and natural resources and prioritizes its residents, economy, and natural environment for a sustainable future.
We celebrate our diversity, and we are an equitable, inclusive community with a high quality of life for all people.
The City provides responsive, friendly, respectful, and efficient public services allowing for inclusion of all people and full community participation for all our residents and businesses.

SETTING THE STAGE
BACKGROUND Of all the destination resorts in the Coachella Valley, Palm Springs is certainly the most famous. The physical beauty, spectacular climate, and unique charm of Palm Springs are known throughout the region, the country, and even the world. In a city as cherished and visible as Palm Springs, the vision for the future is multifaceted and complex, since the City must strive to preserve the delicate balance between its natural and built environments. The ultimate goal of the General Plan is to achieve land uses and development patterns that best meet the needs of residents, businesses, and visitors. Bounded by the Santa Rosa and San Jacinto Mountains on the south and west and the desert on the north and east, Palm Springs is a product of its relationship with its surrounding natural and geographic environments. The expansive desert terrain contributes to the City’s coveted warm climate; the mountains provide a dramatic visual backdrop and shelter from the winds. The proximity to metropolitan Los Angeles, Orange, and San Diego counties, combined with the City’s superior physical setting, is a primary reason that Palm Springs has become a popular resort destination. The area encompassing the present City of Palm Springs was discovered centuries ago by the Agua Caliente Band of Cahuilla Indians, who established their village around the natural hot mineral springs known for their medicinal and healing capabilities. Throughout the 19th century, many explorers, colonizers, and soldiers came through the desert, but it wasn’t until 1853 that United States Topographical Engineers described the combination of palm trees and warm springs they encountered as “Palm Springs.” The name became more commonly used several years later. In 1877, the Southern Pacific Railroad completed its line through the desert to the Pacific Ocean. Early development in Palm Springs was associated with attempts to establish agricultural activity in the area and the southern portions of the Coachella Valley. In the 1920s, the region became a retreat for successful business and movie personalities, who took advantage of the warm weather, the remote location, and the hot water spas. The tourist and resort community of Palm Springs developed over the following decades and dramatically
Page 1-4 Palm Springs 2040 General Plan
changed the character and economy of the Coachella Valley. In 1938, the City of Palm Springs was officially incorporated. Today, Palm Springs not only prides itself on its resort amenities, but also on the village character it has been able to maintain. At the same time, Palm Springs has many major amenities typically found in cities with much larger populations, such as the Palm Springs International Airport, Convention Center, Palm Springs Art Museum, Aerial Tramway, Desert Regional Medical Center, a broad range of public services, and diverse residential neighborhoods. Open space and mountainous areas comprise almost half of the City’s total area and provide treasured natural recreation opportunities and habitat areas.
REGIONAL CONTEXT The City is nestled at the base of the San Jacinto and Santa Rosa Mountains, approximately 60 miles east of Riverside (Figure 1-1). Serving as the “gateway city” for the Coachella Valley, the City of Palm Springs comprises an incorporated area that encompasses 60,440 acres, or nearly 95 square miles; the City’s sphere of influence comprises another 27,160 acres, or approximately 42 square miles. Primary access to the City is provided by Interstate 10 and Highway 111; north–south access to the City is provided via Indian Canyon Drive and Gene Autry Trail.
Sphere of Influence: Established
by the Local Agency Formation
Commission (LAFCO), a sphere of
influence is intended to reflect “the
probable physical boundaries and
service area” of a city. The Sphere
encompasses incorporated and
unincorporated territory. LAFCO is
directed by State law to establish
and periodically review the spheres
of influence for each agency within
its jurisdiction.

ADMINISTRATION
WHAT IS A GENERAL PLAN? State law requires every city and county within California to adopt a comprehensive General Plan. The General Plan represents the community’s view of its future; it becomes a blueprint for a city’s or county’s growth and development. City councils, boards of supervisors, planning commissions, and city staff use the goals and policies of the General Plan as a basis on which to make decisions. The General Plan is considered “comprehensive” since it applies to the territory within the boundaries of the adopting jurisdiction, any areas outside of its boundaries that are within its sphere of influence, and any land outside the City’s boundaries in which the City has determined bears relation to its planning efforts. Since regional planning issues are not necessarily confined to political boundaries, State law allows jurisdictions to conduct planning efforts outside the jurisdiction’s territory. The need to address important issues that transcend local boundaries can facilitate inter-agency planning coordination and result in collaborative planning strategies between neighboring cities or regional agencies such as the Local Agency Formation Commission (LAFCO). The General Plan is also considered comprehensive because it addresses a wide range of issues that affect the City such as the physical development of the jurisdiction or social concerns that can affect the overall quality of life. The General Plan is considered a “long-term” plan since it looks 20 years or more into the future. Each jurisdiction can establish a time horizon that best fits its individual needs. It is not unusual for new information to become available during the life of a General Plan. Alternatively, the vision for the community may change over time, and as a result, General Plans are periodically reviewed and updated to reflect the community’s changing needs. The City of Palm Springs is a charter city and is therefore able to exercise broader powers to enact land use regulations than do general law cities. The City’s charter city status provides it with greater control over its future development and administration.
Charter City Classification
Under the California constitution,
cities are either general law cities
or charter cities. General-law cities
must follow procedures set by state
law and may only exercise powers
granted to them by the State.
Charter cities have full authority
over their own municipal affairs
(such as financing public
improvements or enacting local
ordinances), although they remain
subject to state law on matters of
statewide importance (such as
regulation of traffic and vehicles or
exercising powers of eminent
domain).

HOW THE GENERAL PLAN SERVES OUR COMMUNITY Cities that are thriving and healthy provide their citizens with a quality environment for living, working and recreating. The General Plan is the single most important tool used to help successful communities achieve their vision. The General Plan:
Sets the course for decision making
Helps to balance the competing interests of residents with the needs of visitors and property owners
Helps to inform and educate the citizenry
Serves as an effective management tool for City staff
Provides guidance for economic decisions
Ensure the protection of the natural environment This update process is not intended to craft the General Plan from scratch; instead it streamlines and further refines the existing direction already established by the City in the 2007 General Plan. The General Plan contains state-mandated elements, including Land Use, Housing, Circulation, Safety, Noise, and Parks, Recreation, Open Space and Conservation. Since opportunities for redevelopment and reinvestment into the community are a prominent issue for the City, economic development and improved community quality are a considerable focus of the General Plan and its policies. As a result, two elements were included in the 2007 General Plan to provide additional direction for the City’s future: the Community Design Element and Air Quality Element. Proposals for development, either developer- or City-initiated, must be analyzed and tested for consistency with the goals, policies, and programs in every applicable element of the General Plan. This test of compliance is also a required criterion for determining significant
The City adopted its first General
Plan in 1966. It was significantly
updated in the 1970s, in 1993 and
in 2007.

impacts under the provisions of the California Environmental Quality Act (CEQA). An Environmental Impact Report (EIR) was prepared as a companion document to the 2007 General Plan. The EIR assesses the potential impacts that are generated by the goals, policies, and programs of the General Plan, and identifies mitigation measures to address those impacts. The technical studies prepared for safety, cultural resources, and traffic provided the technical detail used to determine the level of impacts that could be created by the General Plan. An EIR Addendum was prepared for the 2040 General Plan.
SHAPING THE PLAN General Plan preparation is a comprehensive process involving City leaders and staff, residents, community groups, and consultants. “The People are the City”—these words are memorialized above the entrance to the City Council Chambers and encapsulate the vital role of public participation in key decisions affecting the City’s future. Preparing a General Plan, or in this case, an update to the existing General Plan, requires a jurisdiction to conduct a candid assessment of the city—its existing conditions and trends, opportunities and constraints, and vision for the future. The input generated by residents and stakeholders informs the General Plan so that it reflects real-world issues experienced by those who live and work in the community. Before the General Plan can be considered by the Planning Commission and City Council for action, various community members, stakeholders, and members of the business community must become involved and volunteer their expertise and insights to help shape the General Plan.

2007 GENERAL PLAN UPDATE
Advisory Committees
General Plan Steering Committee The Steering Committee was established by the City Council to provide input to the General Plan process. The Steering Committee reviewed the City’s existing General Plan elements and provided feedback on goals and policies that were pertinent to the update and should be retained, those that should be retained but modified, and those that should be removed from the General Plan document altogether because they are complete or no longer relevant. The Steering Committee served as a vehicle to attain representative opinions and attitudes of residents, landowners, interest groups, and other community members interested in providing input that would ultimately shape the outcome of the General Plan. Steering Committee representatives also served as communications liaisons to the public and assisted the planning effort by providing recommendations to staff prior to the presentation of the General Plan document to the Planning Commission and City Council.
Downtown Advisory Group Although Palm Springs is well known as a destination resort, steps must be taken to energize the community to maintain its vitality and to ensure that development opportunities are captured within Palm Springs rather than other cities in the Coachella Valley. In response to increasing development pressures Downtown, and to increase revitalization efforts in the heart of Palm Springs, the Downtown Advisory Group was created. The Downtown Advisory Group was comprised of 15 members representing City Council, Planning Commission, the design community, the Historic Tennis Club Neighborhood, the Palm Springs Economic Development Corporation, the Agua Caliente Band of Cahuilla Indians, the Downtown Merchants Association, the Uptown area of the City, the Historic Site Preservation Board, and the Palm Springs Art Museum. The Downtown Advisory Group was instrumental in the development of a vision for Downtown and the Downtown Urban Design Plan, an interim plan guiding:

adaptive reuse of historic buildings Downtown Palm Springs is the heart of the community. The vitality of the City’s core has the potential to dramatically influence the future of the City economically; therefore, it was critical to develop a strategy to manage its functionality and aesthetic appeal to locals and visitors alike. As development pressures within the City continue to increase, it will also become increasingly important to reposition the Downtown to serve as a major activity center for not only the City, but also the Coachella Valley. The principles and objectives identified in the
Downtown Urban Design Plan were created as a precursor the General Plan and is a proactive and conscientious strategy to protect and enhance the quality of development in the heart of Palm Springs. The Plan addresses and responds to the changing physical, economic, and social environments of Downtown. It was created through the valuable input of the community and a specially developed task force that was charged with reviewing the content and setting direction established in the document.
Public Outreach During the preparation of this General Plan, public involvement was solicited at various points of the General Plan process. Outreach efforts ranged from large-scale community festivals to more issue-oriented discussions conducted in smaller workshops held within the community.
Community Festivals A series of community outreach festivals were hosted by the City at two strategic points in the General Plan Update effort. In May 2005, over 130 people participated in the Plan! Palm Springs Community
Workshop, the first outreach effort designed to obtain preliminary feedback from the community relating to land use, circulation, neighborhoods, open space, parks, and conservation. Participants were asked to vote on the issues that were most important to them.
Page 1-12 Palm Springs 2040 General Plan
This prioritization of issues helped to focus and direct the goals and policies that were identified in each of the elements. The second phase of public outreach was held in January 2007 to prepare the public for a “preview” of the Draft General Plan. The General Plan Preview workshop provided an overview of the General Plan process, how the comments received over the course of the planning effort were incorporated into the plan, and additional ways that the public could comment on the contents of the General Plan prior to its review and action by the Planning Commission and City Council.
Downtown Ideas and Directions Workshop Open to the general public, this outreach effort held in February 2005 was designed to create a forum for stakeholders to express their visions for Downtown Palm Springs and their opinions on current obstacles and opportunities in the Downtown area. Workshop participants were asked to think about the best way to encourage and manage future development Downtown. This workshop provided a valuable forum to create a consensus about the most important issues to be addressed Downtown, and developed potential strategies to address those issues. These strategies ultimately resulted in the development of the
Downtown Urban Design Plan (Appendix A), adopted by the City Council on July 20, 2005, the guidelines complement the policies in the Community Design Element.
Vision-to-Reality Workshops To receive input from the community on the Land Use Plan, approximately 10 smaller-scale outreach meetings were conducted in various areas of the City. Facilitated by members of City Staff and the General Plan Steering Committee, these workshops provided valuable community feedback to the Steering Committee on the proposed Land Use Plan. Input received from each of the community workshops was reviewed, evaluated, and prioritized by the Steering Committee; refinements were then made to the Land Use Plan prior to its presentation to the Planning Commission and City Council.

2040 GENERAL PLAN UPDATE
General Plan Steering Committee A Steering Committee was established by the City Council to provide input to the General Plan process. Over eight meetings, the Steering Committee recommended revisions to the Vision and Priorities, guided updates to the Land Use Plan, and provided detailed feedback on revisions to the Plan’s goals, policies and actions. The Steering Committee also served as communication liaisons and a vehicle to attain representative opinions and attitudes of residents, landowners, interest groups, and other community members.
Public Outreach During the preparation of this General Plan, public involvement was solicited at various points of the General Plan process. Outreach efforts ranged from large-scale community meetings to more issue-oriented discussions conducted in smaller workshops held within the community. The project team also utilized online platforms for communicating information and soliciting feedback.
Community Workshops Citywide workshops were held at two critical junctures during the updated process. The first workshop was held on February 24, 2020 to gather input on the General Plan’s Vision and Priorities and on issues and opportunities related to Housing, Circulation and Land Use. The second workshop was held on July 13, 2021 to solicit feedback on potential changes to the Land Use Plan.
Listening Sessions The Project Team conducted targeted outreach at the request of the City Council to solicit additional feedback from residents and stakeholders related to the General Plan’s Vision and Priorities and topics related to Housing and Environmental Justice. In 2021, four neighborhood community listening sessions were conducted in English and Spanish to obtain input related to the future of Palm Springs—and the many challenges that surround environmental justice as well as accessing safe housing, healthy food, public facilities and community services.
Page 1-14 Palm Springs 2040 General Plan
Digital Engagement Throughout the update process, the City maintained a project website at psgeneralplan.com that provided background information on the project, reported latest news on the project, communicated upcoming engagement opportunities, posted project documents and provided an opportunity for community members to sign up to be notified of project updates by email. Three digital surveys were conducted in English and Spanish in conjunction with major project phases and to supplement in-person engagement activities. The first survey solicited feedback on the General Plan’s existing Vision and Priorities, in conjunction with the first community workshop. The second survey sought to clarify opinions on emerging themes received at the first public workshop and to map perceptions of community assets and opportunities for improvement. A third survey solicited feedback on challenges in gaining access to proper housing, healthy food, parks, public facilities and community services in conjunction with the neighborhood listening sessions.

ADMINISTRATION
GENERAL PLAN PRIORITIES General Plans provide policy guidance related to the seven mandatory elements required by state law. It is common that recurring issues and themes surface during public outreach efforts and evaluation of the plan that require more focused attention and future direction above and beyond that mandated by the state. Focused issues become features of the Plan, and can be used to prioritize use of staff resources and allocation of budget. The following values were identified as the highest priority for Palm Springs, and must be addressed in the General Plan to allow the City to achieve its maximum potential aesthetically, economically, and socially.
Support Palm Springs as a premier desert resort community. Strengthen and promote those things that make Palm Springs a one-of-a kind resort destination, including its natural resources, eco-tourism, its pedestrian- oriented shopping and entertainment districts, its unique architecture, its cultural diversity and identity, the convenience of its airport and convention center, and its wide array of lodging and recreational facilities.
Foster and enhance opportunities for open space. Encourage open space protection and improve visual, physical, and equitable access, where appropriate, to open spaces throughout the community for community enjoyment, health benefits and biodiversity. Where open spaces are accessible to the public, promote safe access for all regardless of age, gender, sexual orientation, ethnicity, race, native language, culture, abilities, and disabilities. Open spaces should include passive and active forms of recreation where possible.
Continue to advance Palm Springs as a sustainability leader. Promote the sustainable use of materials, energy, land, water, air and other natural resources to enhance the long- term livability of our community for all residents regardless of socio-economic position. Reduce greenhouse gas emissions and proactively anticipate and mitigate the impacts of climate change. Reduce wastes going to landfill through source reduction, reuse, recycling and other methods. Encourage and maximize the use of renewable energy resources.
Page 1-16 Palm Springs 2040 General Plan
Diversify and strengthen the City’s economy and promote
education and innovation. Develop and encourage new businesses, employment and education opportunities that will maintain a sustainable, livable, resilient, and diverse economy and workforce. Promote businesses that will provide a living wage. Invest in improving accessible public and private infrastructure for a digital future for all. Promote diverse employment opportunities in a variety of industries.
Maintain, and enhance a diverse range of retail, dining and
entertainment opportunities for local, regional, and tourist
markets. Encourage diverse and appealing shopping opportunities for residents, tourists, and the regional market that will generate sales tax revenues, attract customers from neighboring communities, and enrich the quality of the life for those living in and visiting Palm Springs. Promote and support locally owned businesses and unique shopping experiences that distinguish Palm Springs from other cities.
Provide for a broad range of housing opportunities for all
residents. Encourage development of resource efficient and high-quality housing units at a range of densities for all life stages, economic levels and diversified, multifaceted populations. Identify solutions to reduce rent burden, housing instability, and homelessness.
Create, maintain and enhance unique places and facilities that
foster community interaction and engagement. Improve and facilitate access to parks and other open spaces, community facilities, arts and cultural centers and landmarks in order to promote the City’s rich history, offer visual interest, and support lively activity. Ensure community facilities provide services and amenities that meet the needs of families and individuals to fully enjoy and contribute to life in Palm Springs.
Encourage the creative mixing of land uses to promote vibrant
and walkable neighborhoods and commercial areas accessible to
all. Encourage residential, retail, office, open spaces/recreation and other land uses within commercial and other key locations, to create active, inclusive, and full-service neighborhoods that are less dependent on the automobile. Promote equitable and convenient access to a variety of retail opportunities that serve the needs of daily lives in close proximity to all residential neighborhoods.
Palm Springs 2040 General Plan Page 1-17
ADMINISTRATION
Promote active living, healthy lifestyles and improved
environments for all. To improve mental and physical health, increase opportunities for individuals to incorporate physical activities into daily routines, such as to recreation, exercise and active transportation. Promote healthy food options, and create social and physical environments that improve and the well-being of the community.
Preserve and uphold the distinct architecture and unique visual
and aesthetic form in buildings and neighborhoods that
distinguish Palm Springs from other cities. Promote the identification of unique, culturally diverse neighborhoods while creating strategies and opportunities for improving neighborhoods that have a greater need because of historic disinvestment. Encourage new and characteristically different neighborhood types to develop. Recognize the importance of adaptive reuse for architecturally and historically significant resources.
Provide a circulation system that accommodates the smooth flow
of vehicular traffic and public transportation, encourages safe
bicycle and pedestrian movement, and presents attractively
landscaped corridors. Promote safe and complete streets to ensure a safe and functioning network of circulation corridors and intersections. The streets will be attractively developed and maintained to encourage bicycles, pedestrians, and alternative forms of transportation. Trails, bikeways, and other forms of circulation linkages through the city and into surrounding areas must also be developed and maintained.
HOW TO READ THE GENERAL PLAN
GOALS Each element contains at least one goal statement and related policy statements and implementing programs. A goal in the General Plan is the broadest statement of community values. It is a generalized ideal which provides a sense of direction for action. For example:
Page 1-18 Palm Springs 2040 General Plan
GOAL 1:
Create a safe, aesthetically pleasing, and unified community
appearance within the context of distinct districts and
neighborhoods.
POLICIES The essence of the General Plan is contained within its policy statements. Policies further refine the goal statements, and guide the course of action the City must take to achieve the goals in the plan. It is important to note that policies are guides for decision makers, not decisions themselves. For example:
Policy 1.1 Use public landscaping and signage along streets, sidewalks, and property frontages and in public spaces to strengthen the existing City identity.
ACTIONS Details for implementing policies in the General Plan are contained in the form of action items. An action item describes the specific steps necessary to achieve a policy, and defines the level of commitment to be executed. The key questions that eventually need to be addressed for actions in the General Plan are:
Who is responsible for implementing the action item?
When is it to be carried out?
How much will it cost?
How will it be funded? Actions provide the basis for establishing priorities, scheduling, and assigning staff and other resources to specific actions needed to implement the policies of the Plan. For example:
Example
Example
Palm Springs 2040 General Plan Page 1-19
ADMINISTRATION
Action 1.2 Create a master streetscape plan addressing landscaping, signage, lighting, and special design features along Gene Autry Trail. For the updated Land Use, Circulation and Safety Elements, a separate table of Implementation Programs lists specific actions that should be pursued to implement each goal and policy. Identifying the actions in a separate document approved with the General Plan (but not incorporated in it) allows the City to update the actions as part of the City’s annual strategic planning efforts without warranting an amendment to the General Plan.
POLICY INTERPRETATION For a policy to be useful, it must be clear. However, not all policies are the same; they differ in terms of expected results, commitment of resources, and indication of importance or urgency. Therefore, it is important to simplify the language used in the General Plan and understand the distinctions between the different levels of policy. The following definitions of terms provide guidance in interpreting the policy language of the General Plan; where other action terms are used that are not specified here, they are to be equated to the closest applicable term described below.
Shall: Policies containing the word “shall” indicate that an action must be taken in all cases. This represents absolute commitment to the policy, and the expectation is that the policy will always be carried out.
Should: Policies containing the word “should” indicate that an action will be taken in most cases, but exceptions are acceptable for good reasons.
Encourage: Policies containing the word “encourage” indicate that these actions are highly recommended or desired and should be pursued when feasible.
Allow: Policies containing the word “allow” indicate that a proposed action will be supported within certain parameters and following certain guidelines.
Coordinate: Policies containing the word “coordinate” indicate that an action will occur with another entity, and the City will carry its share of the burden or responsibility.
Example
Page 1-20 Palm Springs 2040 General Plan
Explore: Policies containing the word “explore” indicate that an action will be taken to investigate the subject at hand to discover whether or not some further commitment is in order.
Consider: Policies containing the word “consider” indicate that an action may or may not be taken, depending upon the results of analysis that remains to be completed.
Limit: Policies containing the word “limit” indicate that an action will be taken to keep the subject within certain limits, or will at least make undesired change more difficult.
Restrict: Policies containing the word “restrict” indicate that an action will be taken to keep the undesired action to a minimum.
AMENDING THE GENERAL PLAN The General Plan is not static, but rather is a dynamic and multi-faceted document that defines and addresses the changing needs of the City. It is based on an on-going assessment and understanding of existing and projected community needs. To assure that the General Plan is kept current, short-term programs and policies may be reviewed periodically to reflect compatibility with budgetary priorities and related program status. Long-term programs and implementation measures must also be given consideration to assure timely funding and development of critical infrastructure and public services and facilities.
TIMING Mandatory elements of the General Plan may be amended up to four times in each calendar year. The City Council or any citizen may initiate a General Plan Amendment. It is left to the discretion of the local jurisdiction to establish an amendment schedule to be published one year in advance. State law further requires that the Housing Element be reviewed and updated at least once every eight years.
Palm Springs 2040 General Plan Page 1-21
ADMINISTRATION
APPLICATION PROCEDURES Applications for the amendment of the General Plan and the appropriate fees are filed with the Department of Planning Services. An amendment to the General Plan constitutes a project under the California Environmental Quality Act (CEQA) and, therefore, is evaluated for its environmental effects and consistency with other elements of the General Plan. Final approval of General Plan amendments is the responsibility of the City Council subject to satisfying the environmental requirements imposed by CEQA.
EXEMPTIONS The State Legislature has recognized that occasions arise which require the local jurisdiction to have some flexibility in amending the General Plan. As set forth in the California Government Code, the following are exempt from the General Plan amendment schedule:
Amendments to optional elements.
Amendments requested and necessary for affordable housing (Section 65358(c)).
Any amendment necessary to comply with a court decision in a case involving the legal adequacy of the general plan (Section 65358(d)(1)).
Amendments to bring a general plan into compliance with an airport land use plan (Section 65302.3).
RELATIONSHIP TO OTHER PLANS AND PROGRAMS Although the General Plan serves as the primary means to help the City implement its vision, several other management and implementation tools are needed to ensure that the goals and policies identified here are fully realized.
MUNICIPAL CODE AND ZONING ORDINANCE The City’s Municipal Code and Zoning Ordinance are the primary tools used to implement the goals and policies of the General Plan. The Zoning Ordinance provides more detailed direction related to development standards; permitted, conditionally permitted, and
Page 1-22 Palm Springs 2040 General Plan
prohibited uses; and other regulations such as parking standards and sign regulations. The land uses specified in the Zoning Ordinance are based upon and should be consistent with the land use policies set forth in this element. Changes to the Zoning Ordinance may be necessary due to the adoption of provisions in this General Plan and could require changes to the zoning maps and development standards.
SPECIFIC PLANS While the General Plan provides overall guidance for the physical development of the City, specific plans are used to provide more detailed regulatory guidance for special areas or large developments within the City. Specific plans are generally comprised of a land use plan, circulation plan, development standards, design guidelines, phasing plan, infrastructure plan (water, sewer, or drainage), and implementation plan pursuant to California Governmental Code Sections 65450 through 65457. They are typically implemented as customized zoning for a particular area of the City, and are generally used for large-scale projects that require a comprehensive approach to planning and infrastructure issues. A limited number of specific plans have been approved within the City of Palm Springs: Canyon South, College Park, Downtown, Desert Palisades and Section 14, which are shown on the Land Use Plan (Figures 2-2 and 2-3).
PLANNED DEVELOPMENT DISTRICTS On February 6, 2019, the City Council rescinded and replaced the City’s Planned Development District (PDD) Ordinance based on recommendations provided by an Ad Hoc PDD Committee, which was formed as a requirement of a settlement agreement relative to the City's use of the PDD process. The revised ordinance clarified that the purpose of planned development districts is as follows: 1. Allow development of multiple land parcels under a single development plan. 2. Allow a mixture of land uses, housing types, or zones within a single development project. 3. Allow flexibility in certain development standards, where contextually appropriate, or where necessary to accommodate the development of affordable housing.
Palm Springs 2040 General Plan Page 1-23
ADMINISTRATION
4. Promote innovation and excellence in site and urban design, resulting in projects of significantly higher quality than would be achieved through conventional design practices and standards, and/or the underlying zoning. 5. Promote design variety within a development. 6. Promote open space preservation. 7. Promote more efficient traffic and pedestrian circulation. 8. Promote preservation of natural features or significant historic/architectural features. The updated ordinance limited the types of waivers that are permissible under the prior ordinance, established a pre-application requirement for PDD applications, enhanced the minimum development standards required for PDD projects, and adopted specific criteria and findings that must be met for approval of PDD applications.
DEVELOPMENT AGREEMENTS State law provides for development agreements between a project proponent and the City. The purpose of a development agreement is to provide developers with additional assurances that the policies, rules and regulations, and conditions of approval in effect at the time a project was approved will not be nullified by a future local policy or regulation change. In exchange, the developer may be required to meet certain conditions or performance criteria, which become part of the agreement. Development agreements can be a useful means of meeting General Plan goals and policies while removing some of the risks faced by developers. Agreements can remain in effect for a few or several years, the term typically being set forth in the agreement. It is important to emphasize that, as set forth in the Government Code, the City is not prohibited from applying new rules, regulations, and policies to the property unless specifically stated in the development agreement, nor is the City prevented from denying or conditionally approving any subsequent development project application on the basis of such existing or new rules, regulations, or policies.

Tribal Land Use and
Ownership
In the late 1800s, the United States
government established the Reservation
for the Agua Caliente Band of Cahuilla
Indians (Tribe). The Reservation covers
even-numbered sections within the
Palm Springs area. Although all
Reservation land began as Tribal Trust
Land, some has become Allotted Trust
Land, and some Allotted Trust Land has
been sold to become Fee Land.
Tribal Trust Lands: The United States
holds title to these lands in trust for the
Tribe as a whole, rather than for any
individual. The Tribe retains sovereign
authority over the use and regulation of
these lands.
Allotted Trust Lands: These lands are
former Tribal Trust Lands, the title of
which is now held by the United States
for one or more individual members of
the Tribe (allottees), rather than for the
Tribe as a whole. The Tribe retains
sovereign authority over their uses and
regulation, but the Lands may be
subject to the same development
standards and requirements as land
owned by non-Indians (per land use
agreements between the Tribe and local
governments). With the consent of the
Bureau of Indian Affairs, U.S. Depart-
ment of the Interior, an allottee can sell
or lease such lands. If sold, a parcel of
Allotted Trust Land becomes a parcel of
Fee Land.
Fee Lands: These lands are former
Allotted Trust Lands that have been sold
to a buyer, who then holds fee title to
the land. Although the Fee Lands
remain within the historical boundaries
of the Reservation, they can be owned
by anyone.
SPHERE OF INFLUENCE Land use planning for the Palm Springs does not stop at the City boundaries. Unincorporated lands adjacent to the City’s borders are identified by the Riverside County Local Agency Formation Commission (LAFCO) as areas likely to be serviced or annexed by the City in the future. These lands are known as the City’s Sphere of Influence (SOI). The City does not have regulatory control over these lands, but does have authority and responsibility to designate its preference for land use planning in the County land. The City’s SOI is shown on the Land Use Plan (Figures 2-2 and 2-3).
RELATIONSHIP WITH THE AGUA CALIENTE BAND OF
CAHUILLA INDIANS The form and quality of land development in Palm Springs has been shaped by many factors that are uniquely its own. For example, the climate, regional location, and topography have all influenced the development pattern of the City. In addition, the City is also subject to a unique pattern of land ownership that affects the timing and location of development. The City of Palm Springs is divided into Indian and non-Indian property holdings, based upon a grid pattern of square-mile sections of alternating ownerships. Indian land—which has been subdivided into sections, half-sections, and sometimes even smaller areas—is controlled by the Tribal Council or by individual allottees of the Agua Caliente Band of Cahuilla Indians (the Tribe). Over time, this checkerboard land-ownership pattern has led to an inconsistent pattern of development, since the majority of development has occurred on non-Indian-owned lands. Several strategically located Indian-owned lands, such as Section 14 just east of Downtown, contain vacant parcels, and will play a significant role in the future development patterns for the City. Figure 1-2, Tribal Lands, shows the Indian ownership pattern within the City.

ADMINISTRATION
In the 1970s, the City and the Tribe came to an agreement that recognizes the Tribe’s authority to regulate Indian Trust lands. In addition, the agreement specified that the City would act as the Tribe’s agent to impose City land use regulations and consult with the Tribe with regard to any action that may affect Indian Trust Lands. The agreement established an appeal process designating the Tribal Council as the final authority over land use matters on Indian lands. The City maintains a positive relationship with the Tribe and continues to collaborate with Tribal representatives to develop and apply land use strategies that support the City’s comprehensive land use vision, while concurrently achieving objectives identified by the Tribal Council. The viability of development on Indian land increased significantly when long-term land leases were first implemented in 1959.
GOALS, POLICIES AND ACTIONS Since the General Plan is a blueprint for the future of Palm Springs, it serves as the basis for City staff and the City Council to make strategic policy decisions. The General Plan must be regularly reviewed and updated to ensure that its content is reflective of the community’s changing goals and desires.
ADMINISTRATION The effective implementation of the General Plan relies on the development and maintenance of City regulatory documents, including the Zoning Ordinance, specific plan requirements, and City rules for the implementation of CEQA. The General Plan itself is a living document with mandates for frequent review and refinement. Amendments to the Plan should be given careful consideration and not be granted casually. The goal, policies, and programs in this introductory chapter will help assure the effective administration and implementation of all elements of the Palm Springs General Plan.
Page 1-28 Palm Springs 2040 General Plan
GOAL AD1:
Maintain a contemporary General Plan that serves as a valid
foundation for decision making into the future.
Policies AD1.1 Encourage relevant commissions and boards to meet regularly to evaluate how their respective groups are working to implement the City’s General Plan. AD1.2 Periodically review and update the General Plan to reflect the changing needs of the community. Focus on reviews and updates during economic “down cycles” that anticipate and set direction for anticipated “boom cycles.” AD1.3 Adequately budget for processing amendments to, and conducting comprehensive updates of, the General Plan. AD1.4 Ensure that proposals for new development be analyzed and tested for consistency with the goals, policies, and action items identified in the General Plan. Proposed new land uses that are not consistent with the General Plan shall not be approved. AD1.5 Provide the opportunity for adequate public review and comment for development projects that have the potential to impact the community.

ADMINISTRATION
INTERGOVERNMENTAL COORDINATION The General Plan is a tool that should be used by the County, the Coachella Valley Association of Governments (CVAG), and City boards and commissions to gain a better understanding of City priorities and how those priorities should be addressed in the context of larger planning efforts. As Riverside County and the Coachella Valley continue to experience a high level of growth, it will also be imperative that the City continue to play an active role in regional decision-making efforts. Maintaining strong working relationships with the County of Riverside and CVAG will help to ensure that the City is properly positioning itself to manage future growth in a cooperative manner.
GOAL AD2:
Encourage ongoing land use planning coordination efforts
between City, the Tribe, and regional, state, and federal agencies.
Policies AD2.1 Participate in all relevant local and regional planning efforts. AD2.2 Establish regular lines of communication with local, regional, state, and federal agencies whose planning programs may affect the City of Palm Springs.
Actions AD2.1 Meet regularly with the Agua Caliente Band of Cahuilla Indians to facilitate discussions related to future land use, tourism, and economic development plans on Indian-owned land. AD2.2 Establish working relationships with the Bureau of Land Management and the Conservation Agencies to manage the City’s valuable open space and biological resources. AD2.3 Establish a liaison with the County of Riverside to ensure projects considered within the City’s sphere of influence conform to the provisions of the Palm Springs General Plan.
Page 1-30 Palm Springs 2040 General Plan
AD2.4 Ensure that Palm Springs residents, property owners, and businesses have the opportunity to provide input on regional issues or projects having the potential to impact the community. AD2.5 Evaluate opportunities to annex land in the City’s Sphere of Influence. AD2.6 Ensure that the regional conservation plans are considered during future land use reviews for new applications or land use changes.

2. LAND USE ELEMENT
As the backbone of the General Plan, this element sets forth the distribution, location, and intensity of land uses throughout the City. It represents the land use “road map” for Palm Springs—guiding it into the future with goals and policies. The implementing actions associated with those goals and policies can be found in the General Plan Implementation Programs.
LAND USE PLAN One of the most visible components of the General Plan is the Land Use Plan, which depicts where and how development should occur and provides descriptions of each of the City’s land use designations through text and a land use diagram. State law requires that the general plan identify land use designations and the development intensities that are associated with them for the 87,327 acres of land that are located within the City and Sphere of Influence. In addition, state law also requires that the locations and distribution of the land uses be identified through text and mapping. The locations of each land use can be found on the Land Use Plan (Figures 2-2 and 2-3). The text in this element provides the land use goals and policies that are necessary to achieve the vision. In general, most the City’s existing land uses were retained in place in the new plan. Minor changes to land uses were made for several general reasons: to better align with an existing or intended use that is not anticipated to change before the horizon year of the General Plan (2040); to reflect current ownership; to implement the recommendations of the adopted Section 14 Specific Plan; and to reflect City Council direction on the preferred land use designations for parcels in the College Park Specific Plan area.

PLANNING FOR THE FUTURE
POPULATION AND EMPLOYMENT GROWTH The population of Palm Springs, according to the 2020 census, was 44,575 permanent residents, a growth of 4.1 percent since 2000. At the height of the tourist season, the combined permanent and seasonal population in Palm Springs is estimated to be approximately 74,000, an increase of approximately 66% over the permanent population. That population is currently accommodated in the City’s approximately 35,500 dwelling units. Based upon Table 2-1, Land Use Plan, the City has a potential to generate a maximum of approximately 51,500 dwelling units within the City and Sphere of Influence boundaries by 2040. Using an average household size of 2.08 persons for single-family units and a household size of 1.78 for multi-family units, the City’s maximum population could reach approximately 95,500, assuming that 95% of the City’s housing units are occupied. If the City’s seasonal occupancy rate of 65% were applied instead of a 95% accompany rate, the projected permanent population would be approximately 65,340. At the time of this update, almost 60 percent of available jobs within Palm Springs are categorized within three employment sectors: retail, accommodation and food service, and health care and other services. In contrast, manufacturing and transportation represent only 15 percent of jobs within the City. The Land Use Plan includes enough capacity for employment to increase from approximately 28,000 jobs in 2020 to almost 60,000 jobs over the planning period. Although the Land Use Plan can accommodate significant growth, the Southern California Association of Governments (SCAG) anticipates approximately 28,000 households and 41,000 jobs in Palm Springs by 2035.1 It is important to note that, since the City has limited areas for future development, opportunities to address the jobs-housing balance are somewhat limited. Additional strategies that address housing needs and opportunities within Palm Springs can be found in the Housing Element.

DISADVANTAGED UNINCORPORATED COMMUNITIES
SB 244 Senate Bill 244 (SB 244) requires that cities include in their Land Use Elements identification and analysis of disadvantaged unincorporated communities (DUC) within their spheres-of- influence. A DUC is defined as an inhabited and unincorporated community that includes 50 or more dwellings or registered voters (whichever is less)2, and has an annual median household income that is 80% or less than the statewide annual median household income.
PALM SPRINGS DUC The Riverside Local Agency Formation Commission (LAFCO) is responsible for identifying DUCs in the Coachella Valley region and has determined that one (1) DUC exists in the Palm Springs sphere-of-influence.3 Riverside LAFCO has identified three additional DUCs that exist in close proximity to Palm Springs, but outside of the City’s sphere-of-influence. These include communities in the San Gorgonio (East and West) Area north of Palm Springs and in an area identified as south of Palm Springs/Alpine Village. For each identified community within a City’s sphere-of-influence, the General Plan must address the water, wastewater, storm water drainage, and structural fire protection needs or deficiencies. An analysis of Benefit Assessment Districts or other financing alternatives that could make the extension of such services to identified communities financially feasible must also be included. The assessment summarized in this section and detailed in Appendix G is based on analysis included in an amendment to the Land Use Element adopted on January 15, 2014, and subsequent documentation. The Disadvantaged Unincorporated Community identified within the Palm Springs sphere-of-influence is located at the southwest 2 Definition adopted by Riverside LAFCO, which modifies the definition set forth in SB 244. 3 Summary of Riverside County City DUCs, Riverside LAFCO.

corner of Dillon Road and N. Indian Canyon Drive in the unincorporated community of North Palm Springs. DUC boundaries are shown below. The DUC includes approximately 80 mobile home units at the Carefree Mobile Home Park. Its annual median household income is $37,518 (2006-10 U.S. Census).
Domestic Water The DUC is located within the service boundaries of the Mission Springs Water District (MSWD). The neighborhood has no known issues with its water supply or distribution system. The 2020 Coachella Valley Regional Urban Water Management Plan identifies strategies for the continued reliability of its water supply. No needs or limitations in domestic water services for the DUC have been identified in the Urban Water Management Plan.
Wastewater The DUC is located in the Mission Springs Water District service area. However, d evelopment in the DUC relies on septic systems for wastewater treatment. The DUC is lacking sewer services at this

time. In July 2012, MSWD completed a feasibility analysis for a proposed sewer extension to existing industrial development one (1) mile south of the DUC. However, it is unclear whether or when the proposed industrial sewer extension will occur. It is likely that future connection to MSWD's sewer system will be development driven and will occur as the area builds out.
Storm Water Management The Riverside County Flood Control and Water Conservation District is responsible for regional flood management in the DUC area. In 2013, the District completed the "West Desert Hot Springs Master Drainage Plan" (MDP), which addresses flood hazards in a broad area that includes the DUC. For the DUC, the MDP proposes installation of an 84-inch reinforced concrete pipe with suitable collection capabilities, located within Dillon Road and extending from the westerly property boundary easterly to Mission Creek. This would adequately protect the DUC from storm water flows from the north. Currently, the DUC is lacking storm water protection facilities. However, implementation of the proposed improvements would provide adequate protection from regional flood hazards.
Structural Fire Protection The Riverside County Fire Department (RCFD) provides fire and emergency services to unincorporated areas of Riverside County. The DUC is located within the service area of Riverside Co. Fire Station No. 36 at 11535 Karen Ave, approximately 3 miles northwest of the DUC. Additional support could be provided by two other Riverside Co. Fire Stations and Palm Springs Fire Department (PSFD) Station No. 3. The RCFD and PFSD have a mutual and automatic aid agreement that allows active support regardless of jurisdictional boundaries. The level of currently available fire protection services and facilities serving the DUC suggests that it has acceptable access to structural fire protection.
Financing Alternatives The DUC is adequately served by domestic water and fire protection services. Special funding mechanisms for these services are not anticipated at this time.
Page 2-6 Palm Springs 2040 General Plan
Development in the DUC is lacking connection to a sewer system. MSWD has an ongoing program to connect existing residences currently on septic systems to sewer collectors. Additionally, it is possible that development pressure in the DUC vicinity will bring with it a need to extend sewer services. MSWD has also pursued funding from sources such as State Water Bonds and regional and federal grants. The need for storm water management facilities in the DUC is being addressed by the "West Desert Hot Springs Master Drainage Plan." Financing options to implement the plan could include assessment districts, Community Facilities Districts, or Capital Improvements Programs. Should the DUC be annexed into the City of Palm Springs, the City will have the authority to fund capital improvements through its General Fund or Capital Improvement Program. A number of state and federal agencies periodically offer low interest lands and/or grants to fund public service improvements. The City, in cooperation with service providers, could apply for funding under these programs.

SPECIFIC PLANS While the General Plan provides overall guidance for the physical development of the City, specific plans are used to provide more detailed regulatory guidance for special areas or large developments within the City. Specific Plans have been approved within the City of Palm Springs for the following areas: Section 14, Downtown Palm Springs, College Park, Canyon South and Desert Palisades, which are summarized below.
SECTION 14 SPECIFIC PLAN The Section 14 Specific Plan, originally adopted in November 2004 and last amended in July 2014, provides the vision and implementation measures to guide the development of Section 14 of the Agua Caliente Indian Reservation. The approximately 640-acre planning area is located adjacent to Downtown Palm Springs and is surrounded by the City of Palm Springs on all sides. The Agua Caliente Band of Cahuilla Indians elected to work with the City to prepare the specific plan which pays particular attention to the unique characteristics of Section 14. The Land Use Contract signed in 1977 designated the City of Palm Springs as the Tribe’s agent to enforce land use regulations on the Reservation within the City’s boundaries.
DOWNTOWN PALM SPRINGS SPECIFIC PLAN Adopted in April 2016, the Downtown Palm Springs Specific Plan builds upon the 2009 Museum Market Plaza Specific Plan and the vision of Downtown Palm Springs described in both the General Plan and the Downtown Design Guidelines. The Specific Plan addresses both design considerations and land use guidance for Downtown Palm Springs, with a planning area that encompasses 20.15 acres. The Specific Plan articulates a vision for retail and office commercial space, public plazas, professional office space, and residential development to bring life back to the center of Palm Springs.
Page 2-8 Palm Springs 2040 General Plan
COLLEGE PARK SPECIFIC PLAN The College Park Specific Plan, adopted in December 2010, encompasses approximately 510 acres in the northern portion of the City of Palm Springs. It is envisioned as a master plan to facilitate and coordinate the development of the College of the Desert – West Valley Campus with adjacent and nearby lands. The Specific Plan addresses existing development including the Mountain Gate, Desert Highland, and Gateway Estates neighborhoods, a diversity of multi-family development, and commercial and industrial uses. However, as of this update, the College of the Desert is no longer anticipated to locate at a site in the Specific Plan area.
CANYON SOUTH SPECIFIC PLAN The Canyon South Specific Plan was adopted in July 2003 and subsequently amended in January 2017. The Specific Plan consolidated several previous planning efforts to develop the land. The project area is located in the southern portion of the City, with the entire planning that encompasses approximately 721 acres. The Specific Plan contains four distinct components which include the golf course redesign and clubhouse remodeling; the hotel and spa construction; existing and proposed residential development; and conservation/open space. The 2017 amendment amended to Specific Plan to designate the Oswit Cone as Planning Area 10 of the Environmentally Sensitive Area Specific Plan land use designation (ESA-SP). The designation provides for greater preservation of open space.
DESERT PALISADES SPECIFIC PLAN The Desert Palisades Specific Plan, adopted in January 2011, set forth detailed development principles and programs to regulate the development of the Desert Palisades community. The planning area is located within the Agua Caliente Indian Reservation and in Planning Area 4 of the ESA-SP Zone on the Chino Cone. The Plan proposes a single-family residential community consisting of a maximum of 110 custom home sites on 100+/- net acres.

Palm Springs 2040 General Plan Page 2-9
GENERAL PLAN LAND USE DESIGNATIONS Land use categories are provided to define the type, density, and intensity of development in any particular area of the City. It is not the intent of the General Plan that all the development within the City be uniform in type. For example, within residential development, a mixture of dwelling types is not only possible, but desirable. The mixture could include single-family detached units, townhouses, and some higher density units that may be condominiums or apartments. The critical issue related to development is the relationship between the different intensities of use and the surrounding neighborhood context, including open spaces and amenities that exist or should be provided to service those uses. It is, for example, important that higher density residential uses be located near parks, convenience shopping areas, and transit, where the residents can easily access and enjoy those neighborhood facilities. The following section describes in further detail each of the land uses identified on the Land Use Plan (Figures 2-2 and 2-3) and the standards associated with each. Each of the land use designations is implemented by a correlating set of zoning designations described in the City’s Zoning Ordinance. It should be noted that there need not be an equal number of land use designations and zoning classifications. In many instances, multiple zoning classifications may be consistent with a single General Plan land use designation. Each of the residential land use designations includes a range of allowable densities. The maximum density signifies the maximum number of dwelling units per gross acre that are allowed in each residential area. For example, the Very Low Density Residential designation allows a range of 2.1–4.0 dwelling units per gross acre. The lower threshold figure for each of these categories represents a minimum amount of development allowed, provided that all other required conditions can be met, and the higher figure represents a potential maximum amount of development that could be located in each area. Additional residential development density is allowed in Mixed Use areas for projects that provide a specified number of units as affordable housing.
Page 2-10 Palm Springs 2040 General Plan
Notwithstanding any other density limit to the contrary, any structure which is lawfully being used as a hotel, motel or other form of transient lodging, but which was originally constructed as and used as an apartment, apartment hotel, or similar use may, by obtaining a conditional use permit as further provided by the Palm Springs Zoning Code, revert the current hotel, motel or transient lodging use back to an apartment use, and may operate the same number of apartment units on the site as the number of apartment units originally approved for development on the site. Building intensities for nonresidential uses are measured by floor area ratio (FAR). FAR is the ratio of the total net floor area of a building to the total lot area and describes the intensity of the use on a site. FAR is noted as the maximum ratio allowed for each associated designation. FAR calculations do not include areas within parking structures or outdoor open storage areas. Figure 2-1 illustrates the FAR calculation concept. Actual density (residential uses) and FAR (nonresidential uses) calculations are determined on a parcel-specific basis. Density and FAR are based on adjusted gross acreage, or net acreage, which takes out acres associated with right-of-way for streets and other requisite infrastructure. Site considerations, such as topography or location, and City policies and regulations, such as development standards in the Zoning Code, may place additional requirements on a property that could prevent the site from achieving the maximum density or intensity established within this General Plan.

1-, 2-, or 3-story configuration (43,560 sq. ft. multiplied by 0.50 equals 21,780 sq. ft.).
Note how coverage (building footprint) varies significantly as the building height
changes to yield an identical FAR.
Page 2-12 Palm Springs 2040 General Plan
RESIDENTIAL LAND USES
Estate Residential (0–2.0 dwelling units per acre). The Estate Residential designation provides for the development of large-lot, single-family residences that are custom in design. This designation is predominantly located in areas adjacent to the City’s hillsides, reflecting the natural and environmental constraints that must be addressed there. Minimum lot sizes are generally 20,000 square feet in this designation.
Very Low Density Residential (2.1–4.0 dwelling units per acre). The Very Low Density Residential is the most prevalent land use designation within the City, representing typical single-family detached residential development. Lot sizes in this land use designation generally range from 8,500 to 16,500 square feet.
Low Density Residential (4.1–6.0 dwelling units per acre). Similar to the Very Low Density Residential designation, the Low Density Residential designation also represents “typical” single-family detached residential development. This designation accommodates typical lot sizes ranging from 8,000 to 10,000 square feet.
Medium Density Residential (6.1–15.0 dwelling units per acre). This residential land use category accommodates a range of residential housing types, including single-family attached, single-family detached, patio homes, duplexes, townhomes, multiple-family, and mobile home projects. Hotels and motels are also permitted that are consistent with the scale and character of the surrounding neighborhoods and do not create significant adverse impacts to the surrounding residential neighborhood.
High Density Residential (15.1–30 dwelling units per acre). Typical development in this category would include duplexes, townhomes, and apartments. Hotels and motels are also permitted if they are consistent with the design and character of the surrounding neighborhoods and do not create significant adverse impacts to the surrounding residential neighborhood.

Palm Springs 2040 General Plan Page 2-13
COMMERCIAL
Tourist Resort Commercial (0.35 FAR for stand-alone
commercial uses; 43 hotel rooms per net acre; 86 rooms per
net acre on Tribal Land). This land use designation provides for large-scale resort hotels and timeshares including a broad range of convenience, fitness, spa, retail, and entertainment uses principally serving tourists. Commercial recreation and entertainment facilities, such as convention centers, museums, indoor and outdoor theatres, and water parks are included in this designation, but should be designed to be compatible with neighboring development. Tourist Resort Commercial facilities are most appropriate in the Palm Canyon Drive and Tahquitz Canyon Drive corridors. It is intended that the primary use in any Tourist Resort Commercial area shall be hotel/tourist-related uses; if residential uses are proposed within the Tourist Resort Commercial Designation (timeshares, condominiums, etc.) they shall be a secondary use ancillary to the proposed hotel uses for each area and shall not exceed a maximum of 30 dwelling units per acre.
Small Hotel Resort Commercial (10 dwelling units per acre). This designation applies to areas with smaller-scale, boutique type hotels that are typically found in the Warm Sands and Historic Tennis Club neighborhoods. It is intended that the small hotel character of these neighborhoods be preserved; as a result, new residential uses or conversion of small hotels to residential uses are permitted as long as they comply with the conversion requirements outlined within the City’s Zoning Code. If damaged or remodeled, existing properties (defined as constructed prior to the adoption of this General Plan update) in this designation that exceed 10 dwelling units per acre may be rebuilt to their historic density and will not be considered non-conforming so long as they are rebuilt at the same scale as the original structures and meet design and massing criteria compatible with the surrounding area. Stand-alone retail and commercial uses are not permitted in this land use designation. Ancillary commercial uses associated with a small hotel use are allowed.
Neighborhood/Community Commercial (0.35 FAR). Areas designated as Neighborhood/Community Commercial provide an opportunity for convenience commercial uses that serve adjacent residential neighborhoods. The commercial opportunities created under this designation are intended to be an integrated element of
Tourist Resort Commercial
Page 2-14 Palm Springs 2040 General Plan
the neighborhood, providing to nearby residents services such as dry cleaners, grocery stores, bakeries, bank and post office branches, bookstores, drugstores, and smaller-scale restaurants. Harmonious relationships between these commercial uses and adjacent residential uses shall be achieved through compatibility of site design, building scale, pathways and circulation design, and architectural treatment of structures.
Regional Commercial (0.50 FAR). Regional Commercial areas are intended to provide for large-scale commercial uses that serve an area larger than the City boundaries. Allowable uses typically include department stores, theatres, and restaurants. Uses such as automobile dealerships that have a regional draw are also included in this land use designation. These uses are generally located in areas that will benefit from a higher level of exposure to residents located outside of the City, such as properties located on Ramon Road adjacent to the City limits and selected properties adjacent to the I-10.
MIXED USE
Central Business District (1.0 FAR; 21–30 dwelling units per
acre). Bounded approximately by Ramon Road, Calle Encilia, Alejo Road and Belardo Road, the Central Business District designation allows for a mix of commercial, residential, and office uses at a higher concentration, density, and intensity than in other areas of the City. The CBD serves as the main activity center and cultural core of the community and, as such, theatres, museums, retail, and other entertainment venues are encouraged here. Uses such as grocery stores, small scale hardware stores, and convenience or pharmacy stores that provide services to the Downtown’s residential population in a mix of national and regional chain stores with local businesses are also encouraged. Wholesale and warehousing uses are among the uses discouraged, consistent with the Downtown Specific Plan. The Central Business District is subdivided into zones or areas that provide for diversity in development standards and land use intensities. These subareas are defined in Appendix A,
Downtown Urban Design Plan. Examples include the gateways into Downtown, Downtown Central Core, and the Downtown Outer Core. The Downtown Central Core (roughly bounded by Amado Road, Tahquitz Canyon Way, Museum Drive, and Indian Canyon Drive) and the Gateway areas (at roughly the north and south ends of the CBD) may be developed with a maximum FAR of 3.5. If
Central Business District
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-15
projects in these areas provide substantial public spaces or plazas, an FAR of up to 4.0 may be developed upon approval of a Specific Plan. The Downtown Central Core may also accommodate up to 70 dwelling units per acre for residential or hotel uses if a Specific Plan is prepared and approved. Mixed use residential projects contributing at least 20% of the proposed units towards meeting the City’s affordable housing goals may developed at a maximum density of 70 dwelling units per acre and an FAR of up to 4.0. For existing buildings that propose upper-floor residential use, there shall be no minimum density threshold required. The minimum density threshold may be lowered from 21 to 10 dwelling units per acre for new mixed-use projects provided that at least 75% of the frontage on the major thoroughfares is public serving commercial use.
Mixed-Use (Maximum of 15 dwelling units per acre for
residential uses and a maximum 0.50 FAR for nonresidential
uses). Uses intended in these areas include community-serving retail commercial, professional offices, service businesses, restaurants, daycare centers, public and quasi-public uses. Residential development at a maximum density of 15 units per acre is permitted; housing projects contributing at least 20% of the units as affordable, towards meeting the City’s affordable housing goals may allow residential densities up to 30 du/acre, or as permitted by the Density Bonus provisions of the Zoning Code. Mixing of uses can occur vertically within a building or horizontally within a mixed-use area. Descriptions of the function and preferred mix of uses in each of the City’s eight mixed-use areas can be found on pages 2-37 through 2-43 of the Land Use Element.
SPECIAL POLICY AREAS Special Policy Area designations have been applied in three areas of the City: the Chino Cone, Palm Hills, and Oswit Cone (Canyon and Alluvial Fan). Due to the environmental and visual importance of these three areas, projects proposed within any of these Special Policy Areas must be of superior design, demonstrate integration with existing natural features and landforms, be sensitive to biological resources of the site, and create a more desirable living environment than could be achieved through conventional subdivision design and requirements.
Additional information related to
the location and desired mix of
uses in each mixed-use area can
be found on page 2-37 of this
element.
Page 2-16 Palm Springs 2040 General Plan
Development densities in the Chino Cone and Oswit Cone are one dwelling unit per forty acres (1 du/40 ac). Development applications in excess of this density may be considered with the submittal of a Specific Plan and its associated environmental documentation, which would, by action, establish a general plan amendment. In all cases, development within the Chino Cone and Oswit Cone Special Policy Areas must be consistent with the Environmentally Sensitive Development Areas Specific Plan Ordinance (ESA-SP) in the Palm Springs Zoning Code. The Palm Hills Special Policy Area allows residential and resort development at a maximum of 1 dwelling unit/hotel unit per acre, not to exceed a total of 1,200 units. Any development proposed in the Palm Hills area will require the preparation of a Specific Plan and a related environmental impact report.
EMPLOYMENT CENTERS (OFFICE AND INDUSTRIAL)
Office (0.35 FAR). This land use designation allows for the development of office uses such as executive, administrative and clerical offices, medical offices, and small office centers. Retail uses in this district should be limited to uses directly related to office operations such as restaurants, office supply stores, and pharmacies associated with a medical building. Hotels may be permitted when appropriately integrated into a business or corporate park.
Industrial (0.50 FAR). Industrial uses typically include research and development parks, light manufacturing, laboratories, and industrial services. Retail commercial uses and offices shall be allowed as ancillary uses to the industrial use to encourage projects that are self-sustaining. Industrial development is not a primary use within the City, and any industrial use proposed should not detract from the City’s desire to be a premier resort community. Industrial uses adjacent to the airport that are customarily incidental to the operation of an airport and airport-related businesses and activities are also included in this designation. New and expanded industrial uses within the City will expand the City’s job base and are therefore important to the City’s overall economic vitality and balance of land use.
Airport. Uses that are reasonably necessary for the proper operation of the Palm Springs International Airport. The Palm Springs Airport Master Plan and Riverside County Airport Land Use
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-17
Compatibility Master Plan shall serve as the primary regulatory documents for airport facilities and related uses.
Regional Business Center (Industrial – 0.50 FAR, Office – 0.35
FAR, Commercial – 0.50 FAR). Generally located at the Indian Canyon Drive and Gene Autry Trail interchanges north of the Southern Pacific Railroad and adjacent to I-10, the Regional Business Center area is intended to accommodate a wide variety of business activities in a multi-use environment. The RBC will provide job opportunities for the residents of Palm Springs and the Coachella Valley. Commercial, office, and industrial uses that can be supported by their proximity to the freeway are encouraged in this area. Uses in this area are intended to provide large-scale development opportunities that serve an area larger than the City proper. Commercial uses can include retail establishments, hotels, automobile dealerships, and other uses that serve a regional population. Business parks and industrial uses are also envisioned under this land use designation. It is envisioned that, over time as market forces demand, additional areas north of the railroad, south of I-10 from Hwy. 111 to Gene Autry Trail may also convert to RBC uses, provided that the appropriate environmental analyses have been conducted and the appropriate infrastructure is provided.
INSTITUTIONAL (SCHOOLS/PUBLIC USES/UTILITIES)
Public/Quasi-public (0.35 FAR). This designation includes government offices and corporation yards, hospitals, City-owned museums, cemeteries, and libraries. The public/quasi-public uses identified on the Land Use Map predominantly reflect existing uses that are located throughout the City to effectively serve the community. Public/quasi-public uses comprise a relatively small component of the City’s total land area.
Public/Utilities. Multiple utilities and service providers operate within the City of Palm Springs. This land use designation applies to facilities such as water storage tanks, sewage treatment facilities and electrical substations.
School. The School designation applies to existing public schools and private schools at the elementary, junior high, and high school levels. Facilities that conduct courses at the collegiate level are also included in this designation. The Land Use Plan identifies existing school facilities and areas that provide future higher education land use opportunities.
Page 2-18 Palm Springs 2040 General Plan
The School land use designation may also include developed open space for playfields, recreational and physical education activities as well as open space that is part of the development of an educational based campus.
OPEN SPACE
Open Space–Conservation (1 dwelling unit per 20 acres). Conservation areas are mainly designated for gently sloping areas of scenic beauty (such as hillsides) and natural landforms (such as alluvial fans) that should be preserved to maintain the City’s unique character. This designation is typically applied in areas that have slope ranges of 10 to 30 percent. Residential uses are permitted as an incidental use in this area, at a maximum density of one unit per 20 acres. The Conservation designation is generally located in the non-mountainous open space areas south of I-10 and north of the Whitewater Wash. Much of this area is located within the Whitewater Floodplain Conservation Area in the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP).
Mountain (1 dwelling unit per 40 acres). Mountain areas are generally defined as the sloping areas located above the toe of the
slope. Mountain areas generally consist of steep slopes. Any areas in parcels in excess of a 30 percent slope may not be used for development or for purposes of calculating density except for purposes of density transfer where two conditions are present. First, a portion of the subject parcel also lies within an area designated for residential use or is otherwise suitable for residential development, and all the extra units allowed can be appropriately placed in these areas. Second, the area not used for residential development is dedicated for open space purposes to the City of Palm Springs or other appropriate accepting agency approved by the City. Off-site density transfer may also be allowed if it can be demonstrated that the additional density can be absorbed by the host site. Density transfers shall be subject to the approval of a development agreement. This designation is very similar to the Open Space–Conservation designation except that residential densities within this area are one dwelling unit per 40 acres.
Desert (1 dwelling unit per 10 acres). This designation is intended to identify areas to be retained to protect natural, scenic, and wildlife resources unique to Palm Springs and to identify areas

where minimal development is desired to protect people and property from environmental hazards such as blowsand associated with the undeveloped desert floor areas. Residential development in this area is permitted if it does not exceed 1 unit per 10 acres and is incidental to the overall desert use. Cluster development is encouraged to respond to the environmental sensitivity of the area. Other permitted uses in this land use designation include recreational facilities and public facilities that comply with the intent of the goals and policies identified in the General Plan. Where mineral deposits are present or are found within areas designated for Desert land use, mineral extraction is permitted, provided that appropriate buffers are established to minimize conflicts between residential and mining uses and the appropriate environmental analysis has been conducted. Renewable energy uses may also be permitted, if located on existing mining sites outside the boundaries of the Palm Springs International Airport Influence Area, and provided the necessary environmental analysis has occurred.
Open Space–Parks/Recreation. This designation is used for regional, local, and neighborhood parks, community centers, public and private golf courses, and any recreational facility operated by a public or quasi-public agency. These areas are intended for “active” recreational uses.
Open Space–Water. Areas designated as Open Space–Water are reserved for flood control or drainage facilities only. Properties under this designation fall within the 100-year flood zone as established by the adoption of Federal Emergency Management Agency (FEMA) flood maps and are subject to sporadic flooding and other hazards. No habitable structures are permitted within these areas.

OVERLAY AREAS
Water course Zone Overlay. The Watercourse Zone Overlay is intended to reflect land uses located within a watercourse area that have either been developed under the provisions of a hold-harmless agreement with the City, releasing it from any liability for damage incurred due to flood waters, or it is a property that is no longer classified as a fringe area of a 100-year flood. The overlay represents the path of the watercourse, but allows for the underlying uses to coexist within the flood designation.
Energy Overlay. Wind Energy Conversion Systems (WECS) are permitted in areas designated with this overlay classification. These areas are predominantly located within areas designated as Desert, Industrial, or Open Space–Water on the General Plan Land Use map. Industrial and clean energy uses in these areas may occupy up to 15 percent of the total acreage located within the industrial and regional business center land uses. The Energy Overlay can be found on Figure 2-3.

2007 General Plan estimates.
3 A 5 percent vacancy rate is assumed for population.
4 Assumes the construction of 850 accessory dwelling units (ADU).
5 It is assumed that half of the units in the Medium Density Land Use designation will be single-family and half of the units will be multifamily.
6 The assumed densities for select parcels have been adjusted to align with the projection for low-moderate income sites identified in the 6th Cycle Housing element.
7 The High Density Land Use designation allows hotels up to 43 rooms per acre; 30 rooms per acre were assumed for areas outside of Section 14.
8 Portions of the CBD fall within the Section 14 Specific Plan and were calculated to correspond with the number of units permitted by the Specific Plan. Additionally,
the number of units projected in the CBD considered the varying heights and intensities permitted at the gateways into Downtown and within the Downtown core.
9 Dwelling unit total accounts for areas that are not developable due to the presence of slopes steeper than 30 percent.
10 Special Policy Areas are applied to the Chino Cone, Oswit Cone and Palm Hills areas. The density, number of units, and types of uses vary in each area.

LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-27
GOALS AND POLICIES For the General Plan to be a successful and useable guide for the City of Palm Springs, it must contain clearly written goals, policies, and implementing actions. The Land Use Element’s goals and policies are described here, while a separate table of Implementation Programs lists specific actions that should be pursued to implement each goal and policy. It is intended that this General Plan support the City’s goals with meaningful and achievable direction identified within each action item. Identifying the actions in a separate document approved with the General Plan (but not incorporated in it) will allow the City to update the actions as part of the City’s annual strategic planning efforts without warranting an amendment to the General Plan each time. It is important to note that additional land use direction is provided within the other General Plan Elements, the zoning code, and redevelopment plans.
BALANCE OF LAND USES Because it is both a resort city and a year-round place of residency for so many people, the balance of land uses in Palm Springs is particularly delicate. The City strives to achieve a balance of land uses that accommodate visitor-serving uses while preserving and enhancing the quality of life of its residents. It seeks to maintain retail development for both populations, a wide range of housing options, and job-generating industrial, commercial, and office uses, while preserving and enhancing the unique character of its neighborhoods. Achieving a balance of land uses also means establishing land uses that provide a strong fiscal foundation for the City. In terms of an economic base, Palm Springs is primarily a resort city, whose future depends on climate, access, cultural, recreational opportunities, and retail opportunities. While many businesses in the City provide retail services to the tourist population, it is equally important that the City’s year-round population is well served. Where long strips of disjointed commercial uses exist along major thoroughfares, the City continues to encourage midblock/corridor residential uses to satisfy housing demand, provide a growing market for retail uses and enhance opportunities for residents to access goods and services without use of an automobile.
Bridge Policies
When the General Plan was
comprehensively updated in 2007,
a series of policies and policy
direction at a level of detail that is
normally reserved for development
standards found in the City’s
Zoning Ordinance were included
as “bridge policies” in Appendix E
until the time that they could be
incorporated into the Zoning
Ordinance.
Because they have not yet been
incorporated into the Zoning
Ordinance at the time of this
update, these “bridge policies”
remain in effect. Once the Zoning
Ordinance has been revised to
include them, they will be removed
from the General Plan document.
Page 2-28 Palm Springs 2040 General Plan
The City has a limited amount of industrial areas, the majority of which are located along I-10 or adjacent to the airport. These job centers are characterized by low-intensity industrial development consisting primarily of administrative, light manufacturing, wholesaling, warehousing and distribution, and other industrial uses typically permitted within business park environments. Larger parcels within designated industrial land use areas are encouraged to implement comprehensive plans that incorporate architectural guidelines, convenient access, and on-site recreational and commercial space. Portions of the City north of I-10 contain wind energy facilities, commercial uses, light and medium intensity industrial uses, and a natural-gas-fueled power plant. Wind turbine generators create significant amounts of clean renewable energy, which benefits Palm Springs and the entire Coachella Valley. This land, together with adjacent county land, is generally considered to be one of the two best locations for wind energy production in the world. These facilities are located away from the City center, avoiding noise impacts to existing and future residents, and also serve as a unique tourist attraction. Wind energy facilities also co-exist with industrial uses adjacent to I-10 and are an excellent example of how the integration of compatible uses can provide multiple benefits, such as energy resources and job-generating uses. Additional opportunities to expand wind, solar, and other renewable resources, as well as co-generation and clean natural-gas-fueled generating resources are encouraged by the City. In addition, new advances in wind energy facilities should be examined to determine if additional opportunities exist to allow commercial and industrial development to co-exist with wind energy facilities to an even greater degree than they do now. Providing accessible open space, recreation, cultural and educational opportunities is also extremely important for the City’s future. Residents and businesses could benefit from the presence of a college campus or satellite university to provide local learning and training opportunities that are currently offered elsewhere. To assist in developing an educated and skilled workforce for the businesses in Palm Springs the addition of a large-scale learning facility would be an asset to the economic and educational welfare of the community. Such a use is envisioned in the Mixed-Use area
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-29
bounded by Tahquitz Canyon Way, Farrell Drive, Baristo Road and Sunrise Way, the former site of the Palm Springs Mall. The Parks, Recreation, Open Space and Conservation Element addresses in further detail the amount and location of public, private, active, and passive parkland available within the City and areas where additional parkland is recommended.
GOAL LU1:
A balanced pattern of land uses that complements the location
and character of existing uses, offers opportunities for the
intensification of key targeted sites, enhances environmental
sustainability, and has positive economic results.
Policies LU1.1 Ensure that development meets or exceeds requirements and standards specified within each land use designation. LU 1.2 Concentrate development to protect open space and natural habitat areas. LU 1.3 Ensure that new land use projects are built with adequate utility and municipal infrastructure capacity to support them. LU 1.4 Promote the expansion of existing facilities or the introduction of new uses that complement the location and character of existing uses, intensify key targeted sites, maximize environmental sustainability, and have positive economic results. LU1.5 Support projects of societal benefit or revenue generation through incentives in the entitlement process. LU1.6 Require new construction to mitigate impacts on the City’s housing, schools, public open space, childcare facilities, and other public needs. LU1.7 Ensure that development is sensitive to natural features, including washes, hillsides, and geologic features. LU1.8 Encourage, where appropriate, high density and high intensity projects to maximize the use of land.
Page 2-30 Palm Springs 2040 General Plan
LU1.9 Sensitively integrate into the community required land uses such as transportation corridors, flood control systems, utility corridors, and recreational corridors. LU1.10 Establish Palm Springs as a leader of land use development practices that contribute to the sustainability and stewardship of environmental resources including air quality protection, energy and water efficiency, natural resource conservation, reduction of greenhouse gas emissions, and resilience to the impacts of climate change.
GOAL LU2:
The City maintains its unique “modern urban village”
atmosphere and preserves the rich historical, architectural,
recreational, and environmental quality while pursuing
community and business development goals.
Policies LU2.1 Preserve the character of selected areas of the City. LU2.2 Require that projects that propose to convert open space areas that are designated “Open Space – Parks/Recreation” to developable areas (for residential, commercial, etc.) offer in-kind replacement of such open space elsewhere in the City, make payment of in-lieu fees, or replace the converted open space through the use of
density transfer. LU2.3 Renovate or replace deteriorating structures through code enforcement. LU2.4 Utilize lot consolidation and mixed-use development to reduce fragmentation of parcels and to facilitate infill development. LU2.5 Require that new development be designed to complement the City’s “modern urban village” atmosphere and unique neighborhoods.
Density Transfer: A mechanism
that allows the relocation of
potential development from an
area where proposed land uses
or environmental impacts are
considered undesirable to another
site chosen on the basis of its
ability to accommodate additional
units of development beyond its
original designation. In Palm
Springs, this tool could be used to
intensify residential and commer-
cial uses in the Central City and to
minimize development in sensitive
areas such as the mountains and
hillsides.
A d ensity transfer is also known as
a “transfer of development rights,”
or TDR.
For additional policies related to
sustainable land use practices, see
the Safety, Circulation, Air Quality
and Recreation, Open Space and
Conservation Elements.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-31
GOAL LU3:
A desert community with high-quality industrial and business
park development.
Policies LU3.1 Require well-planned research and development areas and business parks through design guidelines that support enhanced amenities such as pedestrian connectivity, sustainable landscaping and clear wayfinding. LU 3.2 Expand and revitalize industrial uses within the City through appropriate development incentives in targeted areas. LU 3.3 Prohibit the development of manufacturing uses that operate in a manner or use materials that may impose a danger on adjacent uses or are harmful to the environment. LU 3.4 Accommodate assembly, service, commercial, research, and office facilities as a secondary use in industrial areas. LU 3.5 Encourage small-scale manufacturing uses that support tourism- and design-related uses. LU 3.6 Work with the Chamber of Commerce and other business promotion groups within the City to attract new industrial businesses to Palm Springs. LU 3.7 Facilitate the development of corporate/business centers along Gene Autry Trail with the Palm Springs International Airport as the nucleus.
GOAL LU4:
High-quality, sustainable commercial development that
provides equitable access to a variety of retail opportunities in
close proximity to all residential neighborhoods.
Policies LU4.1 Ensure that sufficient land is designated for commercial use in appropriate areas to support the current and future
Page 2-32 Palm Springs 2040 General Plan
needs of all residential neighborhoods in a manner that responds to changing market conditions and meets the needs of daily life, such as groceries, pharmacies and banks. LU4.2 Ensure that commercial facilities are developed as integrated, attractive centers, with adequate parking, provision for pedestrian access from adjacent neighborhoods when feasible, organized traffic movement for motorists, and safety and convenience for pedestrians. LU4.3 Concentrate retail areas into commercial activity nodes to discourage the development of a “strip” commercial uses, which is characterized by long expanses of commercial building frontage devoid of building separations to provide visual relief. Such nodes shall be separated from one another by permanent open space, parks, major landscaped areas, or residential land uses. LU4.4 Encourage the reuse of underutilized commercial properties and discourage the proliferation of strip commercial centers through rezoning, parcel consolidation, or incorporation of midblock residential development in selected areas. LU4.5 Where appropriate, allow for the integration of small-scale commercial uses to provide a distinct identity to residential areas and to increase the convenience of neighborhood commercial uses. LU4.6 Foster development of commercial centers and small-scale commercial retail in residential areas that enhances the equitable access to such services and provides walkable connections between retail and residential uses.
GOAL LU5:
Lifelong learning opportunities are provided for the residents
of Palm Springs.
Policies LU5.1 Allow for and encourage the development of land uses that provide educational opportunities for the City’s residents.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-33
LU5.2 Work closely with the Palm Springs Unified School District to encourage the joint use of facilities as centers for recreation and cultural activities for the City’s residents. LU5.3 Support the development of educational opportunities that maintain a sustainable, livable, resilient and diverse economy and workforce, including supporting the development of a College of the Desert campus in the City.
NEW HOUSING OPPORTUNITIES The projections associated with the Land Use Element reflect that the City’s population will increase to 95,452 at buildout, which is an increase of 48,025 residents from the current population of 47,427 (as determined by the State of California Department of Finance). Of note, the projected population assumes a vacancy rate of 5%, whereas the Department of Finance estimate of the current population uses a vacancy rate of 34.7%. The lower vacancy rate utilized to estimate the projected population represents the theoretical number of occupied units if most households were occupied full-time and, more practically, simulates higher occupancy levels during the peak season. The City offers a variety of housing options—from exclusive estate homes to more moderately priced single-family homes, multifamily apartments and condominiums. As the City continues to grow, it will be important to ensure a range of housing options are provided, including housing that is affordable to the senior population, first-time homebuyers, and the City’s labor force. As housing demand increases and available land becomes limited, it is anticipated that there will be an increasing trend toward higher-density residential development. Careful planning for the integration of these uses into the fabric of the City’s existing neighborhoods or as infill along the City’s existing commercial corridors will help to fulfill housing needs and maintain the eclectic urban village character found in Palm Springs.
Page 2-34 Palm Springs 2040 General Plan
GOAL LU6:
Housing needs of people with varying incomes, household
sizes, and lifestyles are met within the City.
Policies LU6.1 Facilitate new residential development on vacant or underutilized properties in areas that have been designated for mixed-use or residential use on the Land Use Plan, as appropriate. LU6.2 Encourage new residential infill development by providing streamlined approvals processes. LU6.3 Allow conversion of underutilized commercial centers into new housing opportunity sites. LU6.4 Promote the development of affordable housing through density bonus provisions in certain land use designations. LU6.5 Preserve mobile home parks as a source of safe and affordable housing stock in the City. LU6.6 Promote an equitable distribution of a diversity of housing types for various income levels throughout the City to meet the needs of residents, including encouraging the development of new market-rate apartment buildings, affordable housing and Accessory Dwelling Units (ADUs). LU6.7 Projects desiring to develop at the higher end of the density range of any residential land use designation are encouraged to meet the following criteria:
• Exhibit quality architecture, which is designed to respond to the harsh desert climate and includes appropriate detailing, materials, and architectural elements.
• Establish a complimentary relationship of the housing project to its neighborhood, or the creation of a distinctive character and environment for the neighborhood where none currently exists.
The Housing Element contains
the majority of goals, policies,
and action items related to the
provision of housing in Palm
Springs. The Land Use Element
goals and policies identified below
are intended to complement those
policy directions.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-35
• Include open space in excess of the minimum requirements, including integration of active use areas, natural areas, viewsheds and other amenities. Design of the open space shall give it a distinctive character created through special landscape elements such as fountains, reflective pools, decorative paving, courtyards, and entry elements.
• Create larger building sites through lot consolidation where small, substandard, or irregular lots currently exist.
• Minimize the prominence of parking and garages as viewed from the street.
• Develop or contribute to the provision of social/cultural amenities (on- or off-site) such as parks, recreation centers, museums, schools, and daycare centers.
• Preserve unique or desirable natural and manmade resources. LU6.8 Evaluate and encourage, as appropriate, the conversion of small hotels to housing units.
RESORT DESTINATION IMAGE Palm Springs has always embraced its reputation as a world class resort, holding the titles of “America’s premier desert resort city.” Minutes away from any location in town are bike paths, hiking and equestrian trails, parks, tennis courts, ball fields, retail and entertainment venues and golf courses. The City is also home to the Palm Springs Art Museum, Agua Caliente Cultural Plaza, the Palm Springs Air Museum, Palm Springs Surf Club, and hosts a variety of parades, festivals and special events which are geared toward family recreation and entertainment. Year-round special events blend sophistication and relaxation in a style that is typically Palm Springs. Locals and visitors enjoy many of the City’s unique events such as the Palm Springs International Film Festival, Modernism Week, and Villagefest, the City’s weekly outdoor marketplace.
Page 2-36 Palm Springs 2040 General Plan
The City currently is host to over three and a half million visitors annually. Palm Springs maintains the largest number of hotel rooms in the Coachella Valley: 6,300 of the approximately 19,000 rooms (source: Visit Greater Palm Springs). These accommodations range from small, boutique or bed-and-breakfast-style inns located in residential neighborhoods to multistory resort hotels designed to accommodate larger corporate events. In addition, the Convention Center serves as a major center of business and tourist activity within the City. Providing approximately 261,000 square feet of conference facilities, the Convention Center generates large numbers of conference attendees who support nearby hotel and convention-related busi-nesses and who often extend their stays to take advantage of the recreational activities that Palm Springs has to offer. The City should constantly assess how it can continue to draw increasing numbers of visitors and provide them with a special experience that keeps them returning year after year. Maintaining its status as a premier resort destination is a primary priority for the City. The General Plan land use patterns reflect a concentration of tourist commercial uses predominantly comprised of commercial and hotel uses along Palm Canyon Drive and Tahquitz Canyon Drive. The small-scale boutique hotels that are found among the residential neighborhoods in the Warm Sands and Tennis Club areas also contribute to the City’s charm and its appeal to visitors. Development within these areas must be carefully designed and planned to ensure that it continues to reflect the City’s vision of being a “vibrant and inclusive desert resort community.”
GOAL LU7:
The premier resort destination and cultural center in the
Coachella Valley.
Policies LU7.1 Encourage a diversity of high-quality commercial uses, attractive to both the resident and the visitor, including retail, entertainment, cultural, and food sales, in appropriate areas of the City. LU 7.2 Ensure that visitor-serving uses such as hotels, restaurants, and entertainment uses that generate high

levels of activity are developed in close proximity to the Palm Springs Convention Center. LU 7.3 Continue to host special events that draw local residents and visitors. LU7.4 Pursue and attract high-quality retail uses to the City, and specifically to Downtown. LU7.5 Maintain and enhance the success of existing high-quality retail that is unique and local. LU7.6 Retain viable small hotel uses as a part of the unique character of Palm Springs. LU7.7 Maintain or enhance financial and other incentives to assure the economic viability of small hotels. LU7.8 Support events that attract tourism by providing a variety of recreational facilities and venues. LU7.9 Support hotel and motel development that is consistent with the design and character of surrounding neighborhoods and minimizes impacts on residential neighborhoods.
MIXED-USE AREAS The introduction of mixed-use development, if properly implemented, can add vitality, sociability, land use and transportation efficiency to a City. The mixed-use areas identified on the Land Use Plan are intended to function differently than the typical patterns of segregated uses in that the distribution of uses is generally more concentrated, and uses are also generally mixed either vertically or horizontally within any given area. The mixed-use designation is intended to provide flexibility in land use options to promote growth and development in strategic locations. In general, these special areas are envisioned to be pedestrian friendly with higher densities and intensities than the typical patterns of segregated uses. The mixed-use designation provides the City with the ability and authority to be more proactive in land use decisions for focused areas where new growth and development is desired. The flexibility built into the mixed-use designation increases the potential to attract quality developments that will benefit the City.
Page 2-38 Palm Springs 2040 General Plan
Buildings with a vertical mix of uses often contain retail or office uses on the ground floor with commercial, office, or residential uses on the floors above. Areas with a horizontal mix of uses are most successful when unified by common design themes and tied together by a series of plazas and pedestrian promenades. The mix of uses should promote civic activity, define neighborhood character, and provide places for people to meet and socialize, enhancing the area’s overall quality of life. These areas are intended to provide services and distinct gathering places and activity centers for surrounding neighborhoods and businesses. Introduction of mixed-use development should be targeted for vacant and underperforming sites or areas where the City wants to create a stronger concentration of activity. The scale, size, and mixture of uses in these areas will vary based upon the character of the surrounding areas. Each area has its own special character and identity and plays a unique role in the community; the intent is to have the areas complement each other, not compete with each other. As most of the mixed-use areas identified on the Land Use Plan are proposed along prominent corridors, the introduction of residential uses should be carefully designed to enhance the functionality and aesthetic appearance of the corridor while creating a livable, high-quality housing opportunity. Midblock corridor residential designs are encouraged in projects that apply a mixed-use approach to infill. Site planning and landscape design in mixed-use areas should incorporate pedestrian-oriented amenities, including walkway connections, active use areas, outdoor seating areas, and/or food courts. Integrated interior and exterior spaces are also encouraged. Designs should incorporate shade trees, shade structures, small fountains, misters, and similar techniques that make outdoor areas comfortable year-round. More detailed policy guidance related to corridor residential development can be found in the Community Design Element. The application of mixed-use strategies is most appropriate for:
Vacant parcels within existing development that are suitable for such a mix of uses;
Existing development that can be redesigned to become more contemporary, efficient and functional in its use of the land;
Existing development that can be intensified or rehabilitated to become more productive;
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-39
Existing uses that can be removed, replaced, and redeveloped; or
A combination for these strategies where properties are characterized by a mix of suitable conditions. Several of these conditions are found along Palm Canyon Drive and in the northern part of the City. While much of the City is already built out, these areas provide the City with opportunities to facilitate the redevelopment and revitalization of underutilized properties and development of vacant lands. This General Plan specifies eight areas where the mixed-use designation will apply. Following are descriptions of those areas, and the mix of uses that is envisioned for each. While the density and intensity standards identified for the mixed-use designation provide a good level of flexibility, projects proposed in mixed-use areas must demonstrate consistency with the intent of the mixed-use designation for the specific district in which they are located. If the project does not support the intent of the designation, a general plan amendment to a single-use designation may be required. Development in mixed-use areas may be implemented by a Specific Plan or through conventional zoning designations. The intent and scale of each mixed-use area is unique. Table 2-3 illustrates the preferred mix of uses (by total land area, not individual parcels) by area. While this ratio of uses should be used as a target to help guide development, the ultimate composition of each area may vary in response to market conditions and overall long-term development.

Indian Canyon Drive and San Rafael Drive The northwest corner of Indian Canyon Drive and San Rafael Drive is characterized by a collection of small industrial businesses, multifamily residential uses and several vacant parcels. This area provides a prime opportunity to introduce a mixed-use area that contains uses that would be complementary to a new residential neighborhood, which is proposed a block north of this area. Local residents would like to see more neighborhood-serving commercial uses in lieu of additional industrial development.
Preferred mix of uses: 40–50 percent industrial, 15–25 percent residential, 25–35 percent commercial
Artist Colony The north end of Palm Canyon Drive is characterized by a series of underutilized and vacant commercial centers that, at first glance, provide a deteriorating image of the City as visitors travel toward Downtown. Overall, the northern end of the City lacks distinct gathering places, with residents and businesses relying mainly upon Downtown to serve this need. The Artist Colony provides a prime opportunity to introduce housing along the Palm Canyon Drive corridor and to provide much needed neighborhood-serving commercial uses and gathering spaces.
Preferred mix of uses: 40–60 percent residential, 15–25 percent office, 20–35 percent commercial

Uptown Immediately north of the Downtown, the Uptown mixed-use area is located along North Palm Canyon Drive and North Indian Canyon Drive, north of Alejo, south of Via Escuela. A collection of art galleries and boutiques are located here, along with a regional medical center and related medical and professional office uses. A more vibrant retail/commercial area serving the needs of the adjacent residential neighborhoods of Las Palmas, Vista Las Palmas, Movie Colony, and Ruth Hardy Park are needed in this area. A concentrated mix of uses here could stimulate activity and create a sense of place by connecting new residential uses with the nearby medical offices, including the Desert Resort Regional Medical Center, and specialty shopping in the Heritage District. The primary purpose of a mixed-use center in the Uptown area is to generate a synergy between complementary uses that can ultimately result in a gathering place for residents and businesses in the northern end of the City.
Preferred mix of uses: 30–40 percent residential, 30–40 percent commercial, 20–30 percent office
Vista Chino and Sunrise Way Health care services and neighborhood-serving commercial uses abut all corners of the intersection. Established residential areas surround these uses except to the south and east of Cerritos at Vista Chino where there is open space and undeveloped land near the airport. Smaller-scale, neighborhood-serving, commercial development integrated with a unique residential opportunity is envisioned for the northern portion of this site, providing a gathering place within walking distance for the residents living in the adjacent neighborhoods. The expanded Campus of the DAP Health, including commercial, medical (public/quasi-public), residential and social services, is envisioned for the portion of the site south of Vista Chino. The character and scale of this mixed-use area is smaller than those along Palm Canyon Drive; building design should maintain a lower profile consistent with the heights of the adjacent uses.
Preferred mix of uses: 30–40 percent residential, 40–50 percent commercial, 10-20 percent public/quasi-public medical uses.
Page 2-42 Palm Springs 2040 General Plan
Palm Canyon Drive and Sunny Dunes Road The Sunny Dunes and Palm Canyon Drive mixed-use area currently contains scattered commercial uses and large vacant parcels. Different from the mixed-use areas identified above, the Palm Canyon Drive and Sunny Dunes Road area is envisioned as a mixed-use area creating an office, retail, and residential node just south of Downtown. This mix of uses will complement the hotel uses along East Palm Canyon Drive by providing a concentrated commercial and office base in close proximity to visitor accommodations.
Preferred mix of uses: 40–60 percent commercial/office; 40–60 percent residential
Smoke Tr ee The Smoke Tree mixed-use area is located along East Palm Canyon Drive, between Sunrise Way and Barona Road. Smoke Tree is ideally located to serve the needs of surrounding residential neighborhoods, and is characterized by its intimate scale, pedestrian orientation, and vibrant human activity. The purpose of this area is to create a unique mixed-use center characterized by pedestrian-oriented retail shops, restaurants, hotel facilities, and multifamily residential uses. Vacant and underutilized parcels, such as the former Coco’s site east of Smoke Tree Lane and the vacant site west of Smoke Tree Lane, provide opportunities for multifamily residential infill development.
Preferred mix of uses: 30–40 percent residential uses, 60–70 percent commercial
Palm Canyon East Gateway The parcels on the south side of Palm Canyon Drive between Palm Hills Road and the city boundary provide an opportunity for an iconic mixed-use development that serves as a gateway to the City. The General Plan envisions a mix of commercial and residential uses of modest scale that respects the natural features of the site and surrounding area. Due to the possibility of sensitive environmental constraints in this area, an appropriate level of environmental analysis would need to be conducted to determine the viability of any proposed project.
Preferred mix of uses: 40–60 percent residential uses, 40–60 percent commercial
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-43
Higher Education Campus Located along one of the City’s most visible corridors, the site of the former Palm Springs Mall presents an opportunity to inject new vitality along Tahquitz Canyon Way, which serves as the City’s most important east-west corridor linking Downtown and the Airport. As the future home of a campus for the College of the Desert and ancillary uses, this node will provide an opportunity for more efficient use of an underutilized commercial site that can complement the civic and office uses currently existing along the corridor, while strengthening the site’s ongoing community-oriented role as a cultural center. A restaurant, hotel or commercial enterprise operated by the school and used for instructional purposes shall count towards the ratio of school and associated uses. Residential uses associated with the College could count towards the ratio of school and associated uses as well. Retail or office uses not operated by the school shall count towards the target ratio of commercial/office uses.
Preferred mix of uses: 20-40 percent commercial/office, 60-80 percent school and associated uses
GOAL LU8:
Mixed-use infill projects are strategically introduced in
underutilized areas to create neighborhood activity centers
serving the day-to-day needs of nearby residents, employees,
and visitors.
Policies LU8.1 Encourage new mixed-use developments in areas that are currently vacant or underutilized. LU8.2 Encourage flexibility of design in development by allowing both a vertical and/or horizontal mix of uses. LU8.3 Encourage and accommodate the development of specialty uses such as boutiques, art galleries, bookstores, restaurants, coffee shops, interior decorators, hardware stores and other similar uses that cater to the residents and create community gathering places in close proximity to mixed-use areas.
Page 2-44 Palm Springs 2040 General Plan
LU8.4 Allow designated mixed-use areas to contain buildings that are taller than the surrounding neighborhood, where appropriate. LU8.5 Provide pedestrian links between the commercial, office, and retail uses within mixed-use areas to minimize vehicular traffic. LU8.6 Allow for and encourage the development of facilities and gathering places that provide for the social and health needs (daycare centers, social-service providers, medical facilities, etc.) of the residents within mixed/multi-use areas. LU8.7 On-site parking is encouraged to be accessed from side streets or public alleys to minimize traffic impacts on major streets and to avoid interruption in the street-front design of commercial centers. LU8.8 Cluster development where appropriate to create centers of activity or to preserve natural features. LU8.9 Allow for boulevard residential uses as long as the proposed residential uses are consistent with the midblock corridor residential goals and policies found in the Community Design Element in such a way as to minimize noise impacts between residences and areas of heavy traffic.
MOUNTAINS AND HILLSIDES The remarkable landforms created by the San Jacinto and Santa Rosa Mountains are a defining characteristic for Palm Springs as well as one of the City’s most coveted resources. Wrapping around the developed areas of City to the west and south, the steep topography of the mountains provides the City with a dramatic visual backdrop and scenic views that are unparalleled in the Coachella Valley. Over the years, Palm Springs residents have reaffirmed that the hillsides are an irreplaceable asset to their community. Development projects proposed in the hillsides have either been overturned through a vote of the residents or have required additional, more detailed environmental analyses. Efforts to establish a future direction in these areas is further complicated by the need to coordinate with multiple property owners and Hillsides are some of the most
recognizable features in Palm
Springs.

agencies such as the Agua Caliente Tribe and the Bureau of Land Management. As available land in the central city becomes scarce, it will become increasingly important to establish guidance for the protection and thoughtful development of these areas. The intent is to ensure that proposed development is carefully designed to respect the hillsides and their sensitive biological resources. Residential uses are extremely limited in these areas. New development must be of high quality and sited in ways that preserve or protect the City’s valuable natural landforms. The importance of the mountainous areas was further emphasized by the City Council, which (in 2004) established the Citizens’ Task Force for Mountain and Foothill Preservation and Planning to evaluate the City’s land use policies for mountainous areas and provide recommendations that would protect the scenic values of Palm Springs. As part of its effort, the Task Force established the following Guiding Principles that serve as a basis for decision making in the mountainous areas of Palm Springs:
The unique natural environment of Palm Springs with its rugged mountains and sweeping desert sands creates stunning vistas with a sense of space and distance and is Palm Springs’ most important asset.
This natural environment has historically drawn people to live here and made Palm Springs a world class resort destination, and the protection of this natural environment is vital to the well-being of its residents and to sustaining its tourism-based economy.
All land uses must respect the scenic values of the desert and mountain terrain and protect this community asset.
The mountain region is an extraordinarily rich, though fragile, natural environment which sustains a variety of wildlife and plant species, some of which species are threatened or endangered and the City’s land use policies must address ecosystem interactions and protect and conserve sensitive habitat.
Development must be harmonious with, adapted to and respectful of the natural features with minimal disturbance of terrain and vegetation, use of natural and sympathetic materials, and be located in a manner sensitive to terrain, including wildlife habitat, watercourses, and steep slopes.
Page 2-46 Palm Springs 2040 General Plan
Open space is a limited and valuable resource which is a part of the City’s heritage and the City should identify sensitive open space areas for conservation and should acquire and preserve such areas.
The City should continue its policies for open space acquisition and designation, including mitigation of developer impacts through land dedication, density transfer and payment of in-lieu fees, acceptance of gifts of land, obtaining federal and state grants for conservation, working with regional conservation agencies, and developing other funding sources.
GOAL LU9:
The City’s unique mountain resources are preserved for future
generations.
Policies LU9.1 Design and landscape hillside development and development adjacent to natural areas to preserve natural features and habitat. LU9.2 Preserve the frontal slopes of the Santa Rosa and San Jacinto Mountains above the toe of the slope including Chino Cone and Snow Creek. LU9.3 Preserve the unique topographic and geologic features of the City. LU9.4 Windfarm development on hillsides visible from scenic highways and corridors or on slopes of 15 percent or greater should demonstrate no significant adverse aesthetic impacts or provide adequate mitigation prior to approval. LU9.5 Pursue and encourage the acquisition of environmentally sensitive hillside parcels by the City, public trusts or other conservation-oriented entities where such parcel acquisition contributes to city-wide open space conservation goals and plans. LU 9.6 Prohibit modifications and disturbances to mountainous areas, including from motorized vehicles operating outside of City-approved roads.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-47
LU9.7 Encourage the use of mountains for recreational purposes so as not to degrade habitat areas; existing trails will be maintained and new trail links can be developed. LU 9.8 Prevent invasive and non-native plant species from propagating in areas adjacent to naturalized open space and mountainous areas. LU 9.9 Protect the scenic beauty of the mountains from erosion caused by development.
A THRIVING DOWNTOWN Downtown Palm Springs enjoys a worldwide reputation as an authentic pedestrian-oriented commercial center and the City’s recognizable historic core. The Downtown truly serves as the functional, economic, and psychological heart of Palm Springs. It is a heavily visited area of town, has a collection of outstanding architecture and urban design features, and has a concentration of popular restaurants and stores. Community events such as Villagefest, cultural amenities such as the Village Green Heritage Center and the Palm Springs Art Museum, and visitor-serving uses such as the Convention Center, Agua Caliente Cultural Plaza and Agua Caliente Palm Springs Casino bring thousands of visitors Downtown. However, over the years the Downtown area has failed to reach its potential as a thriving community core and has struggled to compete with neighboring cities for new retail opportunities for its residents and visitors. Efforts to reenergize and revitalize this area will help to bring new activity and new life into the City’s core. It is envisioned that Downtown will become a high-intensity, mixed-use area characterized by residential, office, commercial, and entertainment uses. To stimulate vitality, the Downtown will contain activity areas with differing intensities, which are further defined by the scale and design of buildings in each area. The recent creation of a central public park adjacent to the art museum was envisioned to serve as the primary gathering place for visitors and residents of Palm Springs

Although not required by state law, the City has developed the Downtown Urban Design Plan and Downtown Specific Plan to guide the future of development Downtown. Performance criteria related to building height, orientation, and massing, as well as customized guidance for parking, architecture, landscaping, lighting, and street furniture in the Downtown area can be found in both documents. The goals and policies identified below serve as the foundation for future land use and economic strategies proposed Downtown and are intended to complement the direction identified in the Downtown Urban Design Plan and Downtown Palm Springs Specific Plan.
GOAL LU10:
A vibrant, pedestrian-friendly Downtown serves as the
economic, civic, historic, cultural, and recreational center of
the City.
Policies LU10.1 Encourage development of housing and mixed-use land uses Downtown to increase activity in this area. LU10.2 Encourage development that promotes a flow between indoor and outdoor activities such as outdoor cafes, arcades, paseos, and courtyards. LU10.3 Accommodate a broad range of uses Downtown to meet the needs of both residents and visitors and to stimulate both daytime and evening activity. LU10.4 Facilitate and promote special events and community celebrations in the Downtown area to stimulate its role as a community focal point. LU10.5 Strengthen the unique sense of place currently present in Downtown by preserving and incorporating cultural uses, the arts and historic resources. LU 10.6 Provide a logical transition between land uses and the built environment in Downtown and those proposed in the Section 14 Specific Plan.

for film festivals, premieres, and live stage productions, while preserving its historical value. LU10.8 Pursue improvements to the public realm that enhance Downtown as a centerpiece of community activity and identity.
PALM SPRINGS INTERNATIONAL AIRPORT The Palm Springs International Airport serves as the primary air transportation access point to the Coachella Valley communities Located on over 930 acres of land on the eastern edge of the City, the airport not only serves as a major transportation and tourist hub, but is also an asset to the City’s economic development. In 2022, a new annual record high of approximately 3 million passengers flew into and out of the airport. New annual records were also set for flights and seats in 2022. As the number of aircraft trips grows, it will become increasingly important to ensure that the surrounding land uses are compa-tible with airport activities and the City continues to build upon the economic potential and business relationships generated by the airport. High-quality industrial and business park uses should also be promoted in this area. The Palm Springs Airport Master Plan (2015) is currently being updated to evaluate future airport facilities needs, both existing and future, and to develop an airport development plan concept, which could include long-term land acquisition needs related to airport expansion. In addition, the Riverside County Airport Land Use
Compatibility Plan (ALUC) was adopted in February 2005 and provides guidance related to the compatibility of land uses surrounding the airport. Since lands around the immediate vicinity of the airport are generally built out, , it will be important to address how these uses are affected by any future expansion of the airport.
The Palm Springs International Airport serves as a major
transportation hub in the Coachella Valley.
Additional discussion about
hazards related to the airport can
be found in the Safety Element.
Page 2-50 Palm Springs 2040 General Plan
GOAL LU11:
The Palm Springs International Airport is the premier flight
center of the Coachella Valley.
Policies LU11.1 Accommodate land uses in the areas surrounding the airport that are economically supportive of, or related to, the airport activities and that are developed in a manner that minimize negative impacts to existing adjacent land uses. LU11.2 Discourage development of sensitive uses such as schools, hospitals, daycare facilities, or new residential in close proximity to the airport. LU11.3 Continue to upgrade and maintain the Palm Springs International Airport as a state-of-the-art facility. New construction and modification to existing structures shall be compatible with the existing Class 1 facade to enhance the image of the City. In the event of the development of a secondary or new primary entrance to the airport, treatment of the view corridor along Baristo Road or elsewhere shall be treated in a manner akin to that of the extant airport entry aligned with Tahquitz Canyon Way. LU11.4 Ensure that proposed land uses and developments around the airport comply with the policies and procedures set forth in the Riverside County Airport Land Use Compatibility Plan and applicable FAA guidelines.
I-10 CORRIDOR As a major goods-moving corridor and passageway, the I-10 accommodates thousands of travelers a day and serves as a regionally significant east–west link to uses within Riverside County and beyond. Similar to neighboring cities that have frontage along I-10, the City of Palm Springs desires to maximize the development potential in this area and facilitate the development of complementary uses that will bring economic vitality to the corridor.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-51
As a part of the 2007 General Plan, the City established the Regional Business Center (RBC) designation and found that this designation should be focused around two specific areas: the interchange of I-10 and Indian Canyon Drive and the interchange of I-10 and Gene Autry Trail. These areas can accommodate the additional traffic that would be generated by the mix of uses proposed and are located adjacent to already developing areas and to interchanges that have undergone improvements. In addition, both of these areas are located in the City proper and would not require annexation prior to development as RBC. It is envisioned that, over time, market demand may support the phased conversion of additional lands north of the Union Pacific Railroad from Desert and OS-W land use designations to RBC. As opportunities arise to develop along the I-10 Corridor, the extension of the RBC designation along I-10 would be encouraged provided that a general plan amendment is processed, the appropriate environmental and traffic analyses have been completed, and appropriate mitigation measures are provided to accommodate the new development. In addition to the implementation of a desirable mix of land uses adjacent to the freeway, the application of high-quality design is a critical component to the success of any development proposed along I-10. Due to the high level of visibility of the commercial and industrial uses adjacent to the freeway, it is important to ensure that these areas are developed in a way that makes a positive visual impression of Palm Springs. Views from freeways serve as windows into the communities beyond. As a result, cities have begun to recognize the importance of treating these significant corridors more as regional Main Streets than backyards—ensuring that buildings maintain a high level of architectural quality and are representative of the desired image of the community and that unsightly storage areas, mechanical equipment, or loading areas are properly screened or sited to minimize their impact on the aesthetic appearance of the area. Such is the case with the I-10 Corridor area and the City of Palm Springs.
Page 2-52 Palm Springs 2040 General Plan
GOAL LU12:
Commercial, office, and industrial land uses along the I-10
Corridor reflect the world class resort status of our city and
provide a strong sense of entry and arrival into Palm Springs
and the entire Coachella Valley.
Policies LU12.1 Concentrate high-quality regional and freeway-serving land uses that reflects an attractive, well-designed first impression of the City along the entire I-10 frontage, while protecting environmental resources. LU 12.2 Promote the development of regional business center, freeway commercial uses, energy uses, warehouses and distribution centers adjacent to the freeway while maintaining high standards of design and quality of improvements to strengthen the economic vitality of the City. Strip commercial uses are discouraged along the corridor, especially in those areas adjacent to frontage roads. LU 12.3 Support the development of commercial, industrial, and office uses on properties located north of the Union Pacific Railroad that are not currently designated as RBC (excluding those areas designated as OS-W), provided that the appropriate environmental documentation is prepared and the appropriate roadway and utility infrastructure can be provided to support the proposed uses. LU 12.4 Ensure that new development along the freeway corridor is compatible with the City’s policies related to scenic resources. LU 12.5 Periodically reevaluate the concentration, type, and mix of commercial, office, and industrial development that is appropriate and sustainable adjacent to the freeway. LU 12.6 Provide infrastructure and services necessary to support desired development types.
Additional policies addressing
scenic resources and the I-10
Corridor can be found in the
Community Design Element.

Palm Springs 2040 General Plan Page 2-53
SPECIAL POLICY AREAS The General Plan Land Use map identifies three areas of the City that warrant special policy direction—Chino Cone, Oswit Cone, and Palm Hills. These areas warrant custom policy guidance because the City has determined that the preservation of their unique hillside character is of utmost importance and should be carefully guided as development pressures in the hillsides of Palm Springs continue to increase. Following is a discussion of the issues surrounding each of the sites, and the policy direction that accompanies it. The actual locations of these areas can be found on the Land Use Plan, Figure 2-3.
Chino Cone/Snow Creek Chino Cone is recognized as an extraordinary natural resource and an area of great development interest. In 2005 and 2006, the City of Palm Springs formed a task force to establish a vision and direction for the area, which led to the adoption of the Environmentally Sensitive Development Area – Specific Plan (ESA-SP) Ordinance. The ESA-SP zone promotes sensitive development while preserving the natural environment in the Chino Cone area. The General Plan reflects the task force’s vision with goals and policies that undergird the ESA-SP zone. The General Plan goals and policies are intended to provide for the development of environmentally sensitive areas of the city in a manner that will preserve the open, rural character of these areas while allowing development of ranchettes and clustered single- and multiple family or resort projects. The goals and policies of the Special Policy Areas are to facilitate the preservation of open space through the creation and implementation of development review considerations that will ensure the evaluation of the suitability of the land for development in a manner that would preserve the character of the land. The ESA-SP generally includes the Chino Cone, North Palm Canyon Drive north entry corridor, and other areas which the city council may designate from time to time by ordinance. The ESA-SP zone is divided into planning areas as indicated in
Figure 2-4. The General Plan establishes an underlying land use

that any future development in this area
will preserve and incorporate this feature.
Page 2-54 Palm Springs 2040 General Plan
density for all areas within the Chino Cone Special Policy Area of 1 dwelling unit per 40 acres. A specific plan, allowing only sensitive and appropriate uses, densities, distributions, and design standards, is required for each Planning Area for projects that exceed the base land use density. All development in each planning area is required to be consistent with the adopted specific plan. In Planning Areas 3, 4, 5, 6, 8, and 9, a variety of densities and uses including residential resort and commercial, in accordance with the ESA-SP are allowed with a Specific Plan. Specific Plans must show creative and environmentally sensitive development that respects the visual, topographical and unique features of the Chino Cone. Specific Plans for Planning Areas 1 and 7 are recognized as the lowest allowable densities for the Chino Cone Special Policy Area. Planning Area 5a Specific Plans may propose commercial and tourist-serving uses. Following is a brief description of each planning area and some associated characteristics.
Planning Area 1 – Palm Springs Aerial Tramway This area is approximately 570 acres in size and includes the Palm Springs Aerial Tramway Valley Station and accessory facilities. The development in this planning area is envisioned as low density residential and only those commercial uses associated with the Tramway.
Planning Area 2 – Shadowrock This area of approximately 360 acres was previously envisioned with a possible mix of residential and resort uses. However, the area, which features a large alluvial fan, was acquired in 2014 by the Friends of Palm Springs Mountains with the intention to preserve it as open space.
Tramway Road serves as the major access
point into Planning Area 4 of the Chino
Cone Special Study Area.
The Chino Cone is an alluvial fan that can
be easily seen upon entry into the City.

Planning Area 3 – Agua Caliente Band of Cahuilla Indians
Lands The land within Planning Area 3 is within the reservation of the Agua Caliente Band of Cahuilla Indians. The area encompasses roughly 380 acres. It is envisioned that a Tribal Specific Plan would be created for development densities and uses that exceed the residential 1 unit per 40 acres set forth for the Special Policy land use area. Portions of this planning area are also in FEMA Flood Zone A (impact possible with a 100-year flood event).
Planning Area 4 – Tramway South This 119 acre area is characterized primarily by gently sloping rocky terrain. In 2011, the Desert Palisades Specific Plan was adopted to guide development in this area. The Plan proposes a single-family residential community consisting of a maximum of 110 custom home sites on 100+/- net acres within Planning Area 4.
Planning Area 5a – Visitors Center This is an area of approximately 8 acres that includes the architecturally significant Palm Springs Visitors Center and a gateway feature to the City. A Specific Plan for this area may include tourist-serving commercial activities, including retail goods and services primarily oriented to the traveler, including restaurants and entertainment, as well as other uses permitted with a Specific Plan as described in the ESA-SP.
Planning Area 5 – Visitors Center This 36 acre area is just west of Planning Area 5a. Portions of this area abut Highway 111. A Specific Plan for this area may include uses and densities as described in the ESA-SP. Visual screening of development from the adjacent Highway 111 as described elsewhere in the General Plan may be a consideration of development in this area.
Planning Area 6 – Chino Canyon Gateway The Chino Canyon Gateway comprises about 125 acres and portions of this planning area abut Highway 111. Consideration of view sheds and visual screening from Highway 111 may be a consideration of development in this area. Portions of this planning area are also in FEMA Flood Zone A (possible impacts during a 100-year flood event).
Additional regulations governing
the development of the Chino
Cone can be found in the City’s
Zoning Ordinance under the
Environmentally Sensitive Area
Specific Plan Zone.
Page 2-58 Palm Springs 2040 General Plan
Planning Area 7 – Chino Creek There are approximately 176 acres in this planning area, portions of which also abut Highway 111. Environmental analysis should include study of development impacts on the watercourse zones in this Planning Area. Visual impacts of development from Highway 111 should also be considered.
Planning Area 8 – Highway 111 Corridor The 202 acres in this planning area comprise some of the first visual images for travelers entering Palm Springs along Highway 111. A unique rock outcropping known as Ship Rock is a natural landmark in this area. Development in this Planning Area should not minimize the prominence of this natural topographical feature and should address view sheds and visual impacts along the Highway 111 frontage.
Planning Area 9 – Snow Creek This Planning Area is north of the Chino Cone planning areas and encompasses roughly 1,195 acres. Large portions of this area are characterized as watercourse zones. Planning Area 9 is mostly situated within a cove formed by Snow Creek Canyon, providing residents with seclusion and scenic views. The historic Pacific Crest Trail skirts this planning area.
GOAL LU13:
New development is sensitively integrated into the Chino Cone
while preserving its distinguishing natural and scenic
characteristics.
Policies LU13.1 Require that any development in the Chino Cone be harmonious with and respectful of the area’s natural features. LU13.2 Protect and conserve sensitive habitat areas through development restrictions and clustering of land uses. LU13.3 Continue to seek opportunities to acquire or designate open space for preservation. This could include land dedication, in-lieu fees, grants, density transfer, or other sources.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-59
LU13.4 Require street profiles that establish a natural streetscape that visually blends into the surrounding terrain. LU13.5 Require low building profiles, natural colors, and minimal grading to blend into the natural topography of the area. LU13.6 Require any proposed development in this area to preserve monumental rock outcroppings (such as Ship Rock) and integrate these elements into the project’s design. LU13.7 Apply natural berming techniques to screen views of development within the Chino Cone from Highway 111 without blocking views of the mountains. LU 13.8 Allow cultural, educational, and tourism-based uses that will generate revenue and provide amenities in the Chino Cone Special Policy Area.
Palm Hills In July of 1970, the Palm Springs annexed approximately 34 square miles of the San Jacinto and Santa Rosa Mountains into the City. It was envisioned that the area would attract a development that preserved the environment while encouraging the establishment of resort, residential and accessory uses. The majority of the 34 square miles that comprised the original annexation area have been designated as Mountain—allowing up to 1 unit of residential development per 40 acres of land to preserve the integrity of the natural terrain and resources found in the mountains. The remaining area, comprised of approximately 1,200 acres of mountainous terrain in the southern end of the City, has been designated as a Special Policy Area. These 1,200 acres constitute the contemporary boundaries for the Palm Hills area and warrant special policy guidance in the General Plan due to their exceptional location and the desire to minimize impacts of development in the Santa Rosa Mountains. The majority of the site is owned by the Oswit Land Trust which seeks to conserve the land for open space and recreation. The remaining portion in the Palm Hills area - approximately 95 acres - is allotted to members of the Agua Caliente Band of Cahuilla Indians. The City recognizes the value of conserving and preserving the Palm Hills area for the flora and fauna that call the area home, as well as
Page 2-60 Palm Springs 2040 General Plan
those that enjoy outdoor activities in the area. As the City and the greater Coachella Valley continue to grow, the City of Palm Springs will partner with the Oswit Land Trust and conservation organizations to sustainably manage the land for future generations. It should be noted that a 91-unit low density residential subdivision has been approved in the Palm Hills Policy Area. While currently undeveloped, the subdivision is legally recorded and can be developed with little or no additional review required by the City. This land is under the ownership of the Oswit Land Trust, so the potential for development is limited. The City of Palm Springs also recognizes the efforts of the Bureau of Land Management (BLM), the Coachella Valley Mountains Conservancy, and other groups to preserve the Santa Rosa Mountains in their natural state. The City will cooperate with these groups to facilitate conservation to the extent that conservation efforts are consistent with the goals and policies of this General Plan.
GOAL LU14:
Palm Hills reserves valued open space, hillsides, view
corridors, and biological resources, as feasible under
applicable habitat conservation plans.
Policies LU14.1 Require that any new development evaluate and consider the biological resources and natural features of Palm Hills. LU 14.2 Preserve the frontal slopes of the Santa Rosa Mountains that are visible from the desert floor as open space. LU14.3 Public lands that are not used as part of a development project may not be credited for density transfer purposes to an off-site development. LU14.4 Explore opportunities for the exchange of public and private lands to create clearly defined development areas and viable habitat conservation areas.
LAND USE ELEMENT
Palm Springs 2040 General Plan Page 2-61
LU14.5 Limit maximum density allowed to one unit per acre (residential or hotel) and prohibit development on slopes above 30 percent. LU 14.6 Allow credits for density transfer where sensitive biological habitats, including hillsides, washes, canyons, etc. are protected and dedicated as permanent open space. LU14.7 Protect and conserve sensitive habitat areas in Palm Hills that endangered, threatened, or endemic fauna and flora are found. LU14.8 Limit footprint of new development to prevent ecological impacts.
Oswit Cone Oswit Canyon and Alluvial Fan, also known as Oswit Cone, is comprised of 256 acres of vacant land along the southwestern border of Palm Springs. It is located at the foot of the San Jacinto National Mountains and adjacent to the San Jacinto National Monument. The Oswit Cone is a part of the planning area in the Canyon South Specific Plan. In March 2017, the City of Palm Springs adopted Ordinance No. 1919 which established Oswit Cone/ Canyon Alluvial Fan as Planning Area 10 within the ESA-SP zone, with the goal of continuing the area’s role as one of Palm Springs primary eco-tourist destinations. The measure amended the Palm Springs Zoning Code, Canyon South Specific Plan, and Palm Springs General Plan. Development in the Oswit Cone is limited to one dwelling unit for forty (40) acres. Density in excess of this limit can be considered with the submittal of a Specific Plan and associated environmental documentation. Future developments in the Oswit Cone are required to adhere to regulations for the ESA-SP zone, which pertain to permitted uses, property development standards, design standards, and specific requirements for the preparation of specific plans. In addition to uses allowed in Planning Areas 1 through 9, the measure allowed tourist-serving commercial uses, including services primarily oriented to eco-tourism.
Page 2-62 Palm Springs 2040 General Plan
Oswit Cone is an area of cultural and environmental significance. A 2014 study of climate change related changes in water resources of the San Jacinto National Monument referenced in Ordinance No. 1919 found significant archeological features including ancient petroglyphs attributed to pre-Cahuilla Indian societies in the greater Oswit Canyon area. With climate change, the area is expected to have increased migration from the Peninsular Bighorn Sheep, a federally endangered animal.
GOAL LU15:
Oswit Cone remains an eco-tourist destination, with its
distinguishing natural, cultural and scenic characteristics
preserved. LU15.1 Require that any development be respectful of and preserves the archeological artifacts found in the Oswit Cone. LU15.2 Require that any development preserves major natural features that contribute to the character of the Oswit Cone. LU15.3 Require that permitted tourist-serving commercial activities, including services primarily oriented to the eco-tourist, limit and mitigate their ecological footprint. LU15.4 Protect and conserve sensitive habitat areas for the Peninsular Bighorn Sheep and other species that are endangered, threatened, or endemic to the Palm Springs area.

PALM SPRINGS LAND USE ELEMENT | DRAFT IMPLEMENTATION PROGRAMS
July 2024
This section serves as a working checklist of implementation programs for City staff and local decision makers to ensure that the General Plan
vision is realized. The following table of Implementation Programs lists specific actions that should be pursued to implement each goal and policy
in the City’s General Plan. An implementation program is an action, procedure, program, or technique that carries out goals and policies.
Implementation measures are comprehensive in nature, encompassing amendments of existing and preparation of new plans, ordinances, and
development of design standards; administration of City procedures and development review and approval processes; and interagency
coordination.
For each action, a recommended timeframe for completion is noted and the responsible City department is listed. The timeframes are
delineated as follows:
Ongoing: Actions that continue or are periodically implemented through the life of the General Plan
Short: 1-5 years
Mid: When resources become available, but prioritized after 5 years
Long: 10 years or more
The described programs and actions are intended to inform and guide the development of the City’s annual budget. During that time, City staff
will review and prioritize the level of expenditure necessary to carry out the prescribed action and program. Completion of a recommended
implementation program will depend on a number of factors such as citizen priorities, finances, and staff availability.
To enable Palm Springs’ General Plan to serve its purpose effectively, the list of programs and actions need to be reviewed, maintained, and
implemented in a systematic and consistent manner. At a minimum, the programs and timeframes described in this chapter should be
comprehensively reviewed and updated at least once every five (5) years to reflect available fiscal resources, community needs, and priorities.
Revisions to these shall not constitute an amendment of the General Plan, provided that they are consistent with the Vision Statement and carry
out its goals and policies. As such, future revisions to this Implementation Plan will not necessitate environmental review to conform to
California Environmental Quality Act (CEQA) requirements, as each item described in this Plan will require subsequent action and evaluation.
Implementation actions for the Housing Element are included in the Housing Element document, which is provided under separate cover and
updated accordingly to state legislative requirements.

APPENDIX G. DISADVANTAGED UNINCORPORATED COMMUNITIES ANALYSIS
This appendix provides supplemental information about the water,
wastewater, storm water drainage, and structural fire protection
needs or deficiencies in the Disadvantaged Unincorporated
Community (DUC) in Palm Springs’ sphere-of-influence. The DUC is
located at the southwest corner of Dillon Road and N. Indian Canyon
Drive in the unincorporated community of North Palm Springs. DUC
boundaries are shown below.
The DUC includes approximately 80 mobile home units at the
Carefree Mobile Home Park, with an annual median household
income is $37,518 (2006-10 U.S. Census). Single-family and limited
retail commercial development is located in the North Palm Springs
community to the east, and industrial development exists
approximately 1.5 miles to the south along N. Indian Canyon Dr.
Page 2 Palm Springs 2040 General Plan
Domestic Water
The Mission Springs Water District (MSWD) provides water services
to the DUC. MSWD provides domestic water services to
approximately 43,000 people over 135 square miles. MSWD receives
100 percent of its water supply from groundwater produced from
subbasins within the Coachella Valley Groundwater Basin, which
underlies the District’s water service area. 1
Development in the DUC receives domestic water from MSWD; the
park has one 2-inch meter connection that taps into MSWD's 12-inch
line in Dillon Road to the immediate north. Another 12-inch line
extends beneath N. Indian Canyon Dr. immediately east of the DUC.
Water lines within the mobile home park are privately maintained.
The neighborhood is served by a long-standing water purveyor, and
there are no known issues with its water supply or distribution
system. The 2020 Coachella Valley Regional Urban Water
Management Plan identifies strategies for the continued reliability of
its water supply. No needs or limitations in domestic water services
12020 Coachella Valley Regional Urban Water Management Plan
APPENDIX G
Palm Springs 2040 General Plan Page 3
for the DUC have been identified in the Urban Water Management
Plan.
Wastewater
The DUC is located in the Mission Springs Water District service area.
MSWD provides wastewater collection and treatment services to
some development in its service area; however, approximately 5,500
of its customers rely on individual septic tank systems.2
Development in the DUC relies on septic systems for wastewater
treatment. At this time, the nearest sewer trunk lines are located at
the intersection of Dillon Road and Palm Drive, approximately 2.5
miles to the east. In July 2012, MSWD completed a feasibility analysis
for a proposed sewer extension to existing industrial development
one (1) mile south of the DUC. The project study area is generally
bounded by 18th Avenue on the north, Little Morongo Road on the
east, the railroad right-of-way on the south, and Karen Avenue on the
west. Improvements would include 8" to 1O" sewer pipeline
extending along 19th Avenue east to Little Morongo Road to a
proposed 1.5-mgd (million gallons per day) wastewater treatment
plant; a sewer trunk line in 20th Avenue that extends south from
19th Avenue, under I-10, to Garnet Avenue's trunk line; and a lift
station. If constructed, the project would bring sewer infrastructure
to within ¼ mile of the DUC.
The DUC is lacking sewer services at this time. It is unclear whether
or when the proposed industrial sewer extension will occur south of
the DUC. It is likely that future connection to MSWD's sewer system
will be development driven and will occur as the area builds out.
Storm Water Management
The DUC is located on relatively flat desert land that slopes slightly to
the south. Elevations range between 870 and 880 feet above mean
sea level. According to FEMA Flood Insurance Rate Maps 3, the DUC is
located within Zone X which includes '"areas of 0.2% annual chance
flood; areas of 1% annual chance flood with average depths of less
than 1 foot or with drainage areas less than 1 square mile; and areas
protected by levees from 1% annual chance flood." The nearest 100-
year flood zone is approximately ½ mile to the east. Flooding in the

area is typically associated with runoff from the Mission and
Morongo Creeks which drain the San Bernardino Mountains to the
northwest.
The Riverside County Flood Control and Water Conservation District
is responsible for regional flood management in the DUC area. In
2013, the District completed the "West Desert Hot Springs Master
Drainage Plan" (MDP), which addresses flood hazards in a broad area
that includes the DUC. The coverage area generally extends from
State Hwy. 62 on the west, Desert Hot Springs on the east, the
foothills of the San Bernardino Mountains on the north, and
Interstate-10 on the south. The plan proposes an integrated system of
levees, channels, and other drainage infrastructure. For the DUC, the
MDP proposes installation of an 84-inch reinforced concrete pipe
with suitable collection capabilities, located within Dillon Road and
extending from the westerly property boundary easterly to Mission
Creek. This would adequately protect the DUC from storm water
flows from the north.
Currently, the DUC is lacking storm water protection facilities.
However, curb/gutter improvements exist at the intersection of
Dillon Road and N. Indian Canyon Drive, which includes the DUC.
Implementation of the proposed improvements would provide
adequate protection from regional flood hazards.
Structural Fire Protection
The Riverside County Fire Department (RCFD) provides fire and
emergency services to unincorporated areas of Riverside County. The
DUC is located within the service area of Riverside Co. Fire Station
No. 36 at 11535 Karen Avenue, which is approximately 3 miles
northwest of the DUC. If needed, additional fire support could be
provided by:
Riverside Co. Fire Station No. 37 at 65958 Pierson Blvd. in
Desert Hot Springs, approximately 3 miles northeast of the
DUC
Riverside Co. Fire Station No. 24 at 50382 Irene Street in
Cabazon, approximately 13 miles southwest of the DUC
Palm Springs Fire Department (PSFD) Station No. 3 at 590 E.
Racquet Club, approximately 5 miles south of the DUC. The
RCFD and PSFD have a mutual and automatic aid agreement
APPENDIX G
Palm Springs 2040 General Plan Page 5
that allows active support regardless of jurisdictional
boundaries.
The Mission Springs Water District (MSWD) reports that public fire
hydrants are located just outside the DUC boundaries and are fed by
its water meters.
The level of currently available fire protection services and facilities
serving the DUC suggests that it has acceptable access to structural
fire protection.
Financing Alternatives
The DUC is adequately served by domestic water and fire protection
services. Special funding mechanisms for these services are not
anticipated at this time.
Development in the DUC is lacking connection to a sewer system.
Although a nearby sewer extension project has been considered by
MSWD, it is unclear whether or when it will be constructed, and the
DUC is not located within its project boundaries. It is possible that
development pressure in the DUC vicinity will bring with it a need to
extend sewer services. In recent years, voters and MSWD have
created Assessment Districts to fund the elimination of individual
septic systems and extension of the sewer system. Other Community
Facilities Districts also may be feasible. Both of these financing tools
require voting approval by affected property owners. MSWD has also
pursued funding from sources such as State Water Bonds and
regional and federal grants.
The need for storm water management facilities in the DUC is being
addressed by the "West Desert Hot Springs Master Drainage Plan." In
the DUC vicinity, the plan proposes installation of an 84-inch storm
water pipe with adequate collection capabilities to protect the
property from flooding from the north. Should the plan be approved,
the governing jurisdiction (currently the County of Riverside) would
work with property owners and developers regarding prioritizing
and funding the proposed improvements, as well as providing
adequate right-of-way for them. Financing options could include
assessment districts, Community Facilities Districts, or Capital
Improvements Programs. The property owner may have to pay other
fees or provide other improvements suitable to represent the
proposed 84-inch storm water pipe.
Page 6 Palm Springs 2040 General Plan
Should the DUC be annexed into the City of Palm Springs, the City will
have the authority to fund capital improvements through its General
Fund or Capital Improvement Program. A number of state and federal
agencies periodically offer low interest lands and/or grants to fund
public service improvements. The City, in cooperation with service
providers, could apply for funding under these programs.

4.CIRCULATION ELEMENT
BACKGROUND AND CONTEXT Palm Springs’ economic health and quality of life are directly tied to the City’s ability to move people and goods safely and efficiently through the community. The City is world renowned for its tourism industry and can respond to the circulation needs of millions of visitors each year due to the presence of facilities such as the Palm Springs International Airport and the extensive network of recreational trails. Maintaining a Downtown that provides efficient vehicle movement and sufficient parking supply, while providing safe multi modal connections to activity centers, is critical to the City’s vitality. The City’s residential, commercial, and office uses benefit from a circulation network that allows the community to navigate through the City with relative ease, as there are few congested areas that limit traffic flow. An effective circulation system also benefits the industrial community; the movement of goods throughout the region and to areas beyond is essential to its continuing success. The purpose of the Circulation Element is to identify the goals, policies and actions that the City will take to improve the operation of the existing transportation network as the City grows and develops. The objective is to document existing and future transportation facilities in the City of Palm Springs and to develop strategies to address the potential impacts to the circulation network resulting from future land uses identified in the Land Use Element. The Circulation Element will also assure the provision of a transportation system that supports the City’s land uses, is safe for all modes, and facilitates and maintains adequate mobility for its citizens. It encompasses all city managed roadway classifications, truck routes, multi modal facilities, bus and rail transit, air traffic and utilities infrastructure.
The Circulation Element relates
not only to vehicles, bicycles,
pedestrians, and equestrians, but
also the adequacy and reliability of
utility infrastructure including water,
wastewater, electricity, natural gas,
solid waste, and telecommuni-
cations and data transmission
systems.
Page 4-2 Palm Springs 2040 General Plan
RELAT IONSHIP TO OTHER PLANS AND PROGRAMS Of all the elements in the General Plan, the Circulation Element is most closely tied to the Land Use Element. The relationship between proposed land uses and the proposed circulation network serves as a fundamental framework for the other elements of the General Plan. Other elements in the General Plan are affected by the goals and policies identified in the Circulation Element. For example, the Air Quality Element seeks to reduce vehicle emissions, which are directly related to vehicle trips and roadway efficiency as addressed in the Circulation Element. The Circulation Element is also linked to the Safety Element regarding specified routes for the transportation of hazardous materials and the designation of emergency access routes throughout the City. The Community Design Element guides the design and visual appearance of roadways and the pedestrian experience, and the potential noise impacts created by all forms of transportation activity are addressed in the Noise Element. The City’s bikeways and trails provide recreational value and nonmotorized accessibility for the City’s residents and visitors and, as a result, goals and policies for trails can be found in both the Recreation, Open Space and Conservation and Circulation Elements. The successful implementation of the goals and policies in the Circulation Element also requires coordination with regional agencies, including the California Department of Transportation (Caltrans), the Coachella Valley Association of Governments (CVAG), the Southern California Association of Governments (SCAG), the Riverside County Transportation Commission (RCTC), and the SunLine Transit Agency.
CVAG Non-Motorized Transportation Plan Regional planning efforts such as the CVAG Non-Motorized Transportation Plan (NMTP) affect the City’s circulation network. The NMTP is a policy document guiding the development and maintenance of the nonmotorized transportation network, support facilities, and other programs for the Coachella and Palo Verde Valleys over a 20-year period beginning in 2010 when the plan was completed. The plan builds on the region’s first NMTP adopted in 2001 and addresses important issues such as planning, utilization of existing resources, facility design, multi modal integration, safety and education, and support facilities. The plan lays out specific programs, implementation, maintenance and funding of those
Palm Springs 2040 General Plan Page 4-3
CIRCULATION ELEMENT
facilities—all of which should be taken into consideration as the City continues to develop its own circulation network.
CVAG Active Transportation Design Guidelines (ATDG) The Palm Springs Circulation Element includes policies and references to active transportation facilities. The ATDG created by CVAG is a document created to ensure design and facility consistency throughout its jurisdictions. These guidelines take information from existing manuals and a variety of sources and outlines best practices for its member jurisdictions to follow.
CVAG CV Link Conceptual Master Plan Vol. 1 and II This document outlines the plan for a 50 mile long shared use trail for bicycles, pedestrians, and low speed electric vehicles (under 25 mph). The master plan volumes cover trail design, amenities, funding, location, and challenges for the $100,000,000 facility. A portion of CV Link will cross into Palm Springs jurisdiction, and the Link as a whole will connect a transportation user group to surrounding jurisdictions. The CV Link facilities located in Palm Springs are included within the bike facilities and designated trails shown in Figure 4-4 in this Element. CV Link Facilities in the City of Palm Springs vary – some portions of the trail are on-street and some off-street.
CVAG Active Transportation Plan This plan serves as an update and expansion of the NMTP created by CVAG. The Active Transportation Plan describes its integration with other plans, changes compared to the NMTP, the bikeway plan for the Coachella Valley, pedestrian improvement actions, funding opportunities, and design guidance. The City of Palm Springs existing and proposed active transportation facilities are described in this plan.
Airport Plans Lastly, the Riverside County Airport Land Use Compatibility Plan and the Palm Springs International Airport Master Plan (Updated September 2015) provide long-term development programs for the airport to ensure that it will provide a safe, efficient, economical, and environmentally acceptable air transportation facility. The City is also currently leading efforts to update the Airport Master Plan as
Page 4-4 Palm Springs 2040 General Plan
described in the Aviation and Heliport Facilities section. Should the City make changes to its transportation network and related programs, the major objectives identified in both airport plans must be considered to ensure the safety and vitality of one of the City’s most critical transportation facilities.
GOALS, POLICIES AND ACTIONS This section contains goals, policies and actions related to circulation and circulation systems within the City. The issues addressed in this element should be given careful consideration when new development, roads, critical emergency facilities, infrastructure, or other projects are designed.
ROADWAY NETWORK The City’s roadway network is comprised of a hierarchy of streets that provide access to and throughout Palm Springs. The arterials that serve the City predominantly follow a half-mile grid pattern. The fine grid of streets that encompasses the majority of the urbanized area of Palm Springs is extremely important in the effective movement of vehicular traffic throughout the City. Not only does it afford more travel choices for vehicular traffic, it also contributes to the walkable scale of our City. This fine grid of streets, typical of pre-World War II city planning, sets our City apart from others in the Coachella Valley. Figure 4-1, Circulation Plan, illustrates the roadway system that is planned to accommodate the City’s existing and future land uses, as identified in the Land Use Element.
Regional Roadways Interstate and regional access to the City is provided primarily by Interstate 10 (I-10). In addition, access to the City from other Coachella Valley cities is provided by Highway 111. Twenty-Nine Palms Highway (SR-62) connects to the I-10 from the north, and the Palms to Pines Highway (SR-74) connects to Highway 111 from the south, providing additional access to the City. I-10 is a northwest–southeast freeway traversing the northern limits of the City and providing direct access to San Bernardino, Orange and Los Angeles Counties to the northwest, and the State of
The Interstate System was
authorized by the Federal-Aid
Highway Act of 1956, popularly
known as the National Interstate

for all roads that are of national
importance. Generally, it includes
the interstate system; other routes
identified as having strategic
defense characteristics; routes
providing access to major ports,
airports, public transportation,
intermodal transportation facilities;
and routes of particular importance
to local governments.
It should be noted that Indian

Arizona to the east. This facility is comprised of four general-purpose lanes in each direction for its entire length through the City, approximately seven miles. I-10 has four interchanges within the City limits, at Highway 111, Whitewater Canyon Road, Indian Canyon Drive, and Gene Autry Trail.
Roadway Classifications Each roadway located within the City is designated with a classifi-cation depending on its role in the circulation network and its relationship to surrounding uses. The street classifications shown in Figure 4-1 reflect the planned roadway configurations, not necessarily the existing roadway design. Table 4-1 presents minimum standards for some roadway design features by classification. While the following descriptions provide an overview of the general features of each roadway classification, there may be exceptions for individual streets that require modified standards. The City’s circulation network is comprised of five roadway classifications that are depicted on Figure 4-2.
Interstate. Interstates are special purpose, high-capacity, multilane divided highways for regional travel; they connect cities and major thoroughfares into a regional network. Access is strictly controlled at grade-separated crossings to assure uninterrupted traffic flow. Interstates are owned and maintained by Caltrans and are not under the jurisdiction of the City.
Expressway. Expressways primarily serve through-traffic with limited local access. Within Palm Springs, expressways have a minimum of four lanes few cross-streets, and do not allow for on-street parking. Direct access from a single-family residential neighborhood to an expressway is prohibited where alternate access can be provided. Currently, Palm Springs has one roadway designated as an expressway, North Palm Canyon Drive north of Tram Way to I-10, which is under the jurisdiction of Caltrans. Since it is under Caltrans’ control, no City cross-section for this street is provided in Figure 4-2.
Major Thoroughfare. Major thoroughfares serve mostly through-traffic with some local access allowed; in most cases, they do not allow on-street parking except in the Downtown. These roadways form the basic element of the City’s circulation system, connecting Palm Springs to regional
Page 4-6 Palm Springs 2040 General Plan
highways and tying together different areas of the City. Landscaped medians shall be provided on major thoroughfares to maintain an acceptable level of service, to serve as a safety mechanism, and to provide beautification. Major thoroughfares can be either six-lane or divided four-lane roads.
Secondary Thoroughfare. Secondary thoroughfares serve through and local traffic and may allow on-street parking. They connect various areas of the City, provide access to major thoroughfares, and serve secondary traffic generators such as small business centers, schools, and major parks. Typical street right-of-way width has a maximum of 88 feet, which can be divided or undivided.
One-Way Modified Arterial. Similar to thoroughfares, arterials largely serve through traffic with the intent of minimizing traffic patterns that unnecessarily increase congestion. One-way modified arterials provide through capacity with the specific intent of directing traffic in one direction. Palm Springs only has one stretch of roadway classified as a one-way modified arterial. This is Palm Canyon Drive from Alejo to Ramon Road.
Collector. Collector streets serve mostly local traffic; they are usually comprised of two lanes and carry traffic from secondary and major thoroughfares. On-street parking is often permitted on collectors, which can be divided or undivided, modified or unmodified roadways. Maximum right-of-way width for a collector is 80 feet and actual width depends on surrounding land use and historical roadway classification.
Local Streets. Primarily provide access to individual parcels of land. Local Streets can be either public streets or private streets. Maximum right-of-way is 60 feet for local streets. In certain cases, 50 feet right-of-way may be permitted by the City Engineer. Typical street widths for local streets are 36 feet. In Estate, Very Low, and Low Density Residential neighborhoods, local public street widths may be reduced to 28 feet (curb face to curb face) provided that (1) additional off-street parking is provided as determined by the City Engineer, the Fire Chief and Director of Planning, (2) rolled or wedge curb is provided such that vehicles may park partially out of the traveled way, and (3) pedestrian pathways or
Palm Springs 2040 General Plan Page 4-7
CIRCULATION ELEMENT
sidewalks, if located along the street, separated from the curb by a minimum five-foot parkway, are provided. Private streets provide access to individual parcels of land in planned development communities approved with privately maintained access. Access may be restricted with gated entrances/exits to communities. Designated fire lanes in private developments shall be not less than 24 feet wide (curb face to curb face) with no parking on either side unless alternate arrangements are approved by the Palm Springs Fire Department.

CIRCULATION ELEMENT
Vehicle Miles Traveled Vehicle Miles Traveled (VMT) is a metric for assessing the distance vehicles travel and considering how that metric affects the circulation system of a jurisdiction. In compliance with SB 743, the City of Palm Springs now requires a proposed project in the city to study that project’s anticipated impact on VMT within the city. VMT analysis is intended to encourage project developers and cities to consider options to reduce vehicle trip length, frequency, and total volumes, without needing to unnecessarily invest in roadway expansion.
Level of Service Level of Service (LOS) is a qualitative means of measuring traffic congestion as indicated by speed and travel time, traffic interruptions, freedom to maneuver, safety, and driving comfort and convenience on the City’s existing and future roadway network. Levels of service are designated by grades of A (excellent, free flow) through F (failure, congested conditions). LOS can also be represented as volume-to-capacity ratios (V/C), or in other words, the average daily traffic (ADT) volume for the roadway divided by the theoretical roadway capacity as defined by its designated roadway classification. As the V/C ratio approaches 1.0, the roadway approaches LOS F.
Future Traffic Conditions As part of the General Plan Update, a traffic analysis (Appendix B) was prepared to determine the LOS classifications on the City’s future roadway network at buildout. The traffic analysis determined that the dense grid-like structure of the existing circulation system allows traffic to filter throughout the City with minimal congestion-related delay. As a result, future traffic conditions on most City streets are forecast to operate at or above LOS D. Refer to Appendix B for forecast LOS levels for specific streets.
Scenic Highways California’s Scenic Highway Program was created to preserve and protect scenic highway corridors from change which would diminish the aesthetic value of lands adjacent to highways. Currently Highway 111 is classified as Eligible Scenic Highway – Not
Page 4-20 Palm Springs 2040 General Plan
Officially Designated. The status of a State Scenic Highway changes from “eligible” to “officially designated” when the local jurisdiction adopts a scenic corridor protection program, applies to the California Department of Transportation for scenic highway approval, and receives notification from Caltrans that the highway has been designated as a Scenic Highway. It should be noted that the majority of the City’s roadways provide views to the San Jacinto and Santa Rosa Mountains. Although they are not designated by the state as scenic highways, the City’s roadways provide a valuable visual resource for the community. Additional policies related to view preservation in the City’s Scenic/View Corridors can be found in the Community Design Element.
Truck Routes I-10 and Highway 111 are part of the state highway truck route system. I-10 is included in the Surface Transportation Assistance Act (STAA) Network, which allows larger trucks with no maximum overall length. Highway 111 is also included in the STAA Network, except between Gateway Drive and Gene Autry Trail, where it is designated as part of the California Legal Network. Streets proposed to serve as truck routes throughout the City are illustrated in Figure 4-3.
Landscape Medians The City’s circulation plan notes that certain roadways are “divided”; this may mean a raised landscaped median, or a shared left-turn “center lane.” It is the City’s preference that landscape medians be used wherever divided roadway designations are shown unless traffic conditions dictate that the shared center left-turn lane is necessary.

CIRCULATION ELEMENT
GOAL CR1:
Establish and maintain a safe, efficient, interconnected
circulation system that accommodates vehicular travel,
walking, bicycling, public transit, and other forms of
transportation.
Policies CR1.1 Develop a system of roadways that provides travel choices and reduces traffic congestion. CR1.2 Preserve and extend the City’s fine grid of streets to the greatest extent possible. Where possible, allow the grid of streets to curve and meander to slow traffic and to create more interesting streetscapes. CR1.3 Continue coordination/cooperation with adjacent jurisdictions regarding future roadway sections, standards, and improvements. CR 1.4 Preserve the City’s right-of-way requirements and typical cross sections where possible, except where approved by the City Council. CR1.5 Implement roadway traffic-calming mechanisms as identified in the City’s Neighborhood Traffic Calming Program to protect residential neighborhoods from the intrusion of cut-through traffic in areas that have demonstrated traffic problems. CR1.6 Although the grid system of streets is important, avoid the use of long, straight roadway segments on new local streets in new residential neighborhoods, whenever possible. CR1.7 Maintain a truck route system that serves business districts, industrial areas, the Airport, and meets regulations specified in Palm Springs Municipal Code Chapter 12.56 (Restricted Use of Certain Streets). CR1.8 Encourage large employers (employers with 100 or more persons) to adopt incentive programs that include ridesharing, fleet vehicles and vanpools, preferential parking for rideshares, subsidized shuttle bus services, telecommuting, alternative work hour programs, bicycle
Additional policies addressing
specific modes of travel can be

racks, lockers and shower rooms, and information on transit services to reduce overall traffic volumes in the City. CR1.9 Allow for a reduction in parking space requirements for office/industrial uses that implement ridesharing and transit pass programs. CR1.10 Require the owner or applicant of new development projects to address traffic deficiencies. CR1.11 Pursue an aggressive regional posture advocating new and improved transportation solutions, including continued participation in the Transportation Uniform
Mitigation Fee, and planning for changing mobility trends and technology. CR1.12 Private roads shall be developed in accordance with the City’s published engineering standards for public streets, unless otherwise approved by the City Engineer. CR1.13 Require developers, prior to approval of development plans, to provide increased right-of-way through land dedications to accommodate additional demand for dual left-turn and exclusive right-turn lanes, interchange improvements, bus stops and lanes, bicycle facilities or other improvements required to maintain a minimum operating LOS D at critical intersections identified in the General Plan Appendix B. CR1.14 Require developers, prior to approval of development plans, to provide right-of-way through land dedications to accommodate the City’s network of trails and nonmotorized routes. CR1.15 Implement improvements to the existing roadway network such as traffic signal synchronization and upgrading road surfaces.
The County of Riverside and the
Coachella Valley Association of
Governments enacted the Transportation Uniform
Mitigation Fee (TUMF) to fund the
mitigation of cumulative regional
transportation impacts resulting
from future development. The
mitigation fees collected through
the TUMF program are utilized to
complete transportation system
capital improvements necessary to
meet the increased travel demand
and to sustain current traffic levels
of service. The fee calculations are
based on the proportional
allocation of the costs of proposed
transportation improvements,
which are based on the cumulative
transportation system impacts of
different types of new develop-
ment. Fees are directly related to
the forecast rate of growth and trip
generation characteristics of
different categories of new
development.
Palm Springs 2040 General Plan Page 4-25
CIRCULATION ELEMENT
GOAL CR2:
Provide a circulation network that maintains a safe and
efficient system for all travel modes and users of all ages and
mobilities.
Policies CR2.1 Maintain a network of complete streets throughout the city to provide connectivity for all travel modes. CR2.2 Maintain Level of Service D or better for the City’s circulation network, as measured using “in season” peak hour conditions. CR2.3 Make street improvements at problem intersections and bottleneck locations to improve specific traffic operations and safety, with all such improvements to be considered selectively on the basis of specific studies of the affected intersection and streets, and the impacts on the surrounding area and pedestrian activity. CR2.4 Encourage the development of, and cooperate in, valleywide visioning and initiatives to assure an LOS D on I-10. CR2.5 Aim to eliminate fatal and serious injuries for all road users within 25 years, particularly for those most vulnerable, by reviewing roadway design, roadway user behavior, roadway operations, and post-crash care standards. CR2.6 Promote redundant and proactive safety measures, particularly along roadway segments and at intersections identified in the High Injury Network.CR2.7 Consider roadway reconfigurations or lane reductions on roadways operating at LOS D or better, particularly to allocate right-of-way for new or enhanced bike facilities or sidewalks. CR2.8 Improve connectivity and resiliency in and out of the City by constructing all-weather bridge crossings and other infrastructure enhancements along major access corridors like Vista Chino, Gene Autry Trail, Indian Canyon Drive, and Palm Canyon Drive.
Page 4-26 Palm Springs 2040 General Plan
GOAL CR3:
Provide efficient circulation in the Downtown to support its
role as the City’s primary retail center.
Policies CR3.1 Provide an environment within the Central Business District along Palm Canyon Drive and Indian Canyon Drive that is suited to slower traffic speeds and more frequent pedestrian crossings. CR3.2 Consider the use of cross-streets (such as Amado Road, Andreas Road, Arenas Road, and Museum Way) between Museum Drive and Indian Canyon Drive for use as combination street/parking and/or pedestrian zones. CR3.3 Support recommendations from the Section 14 and Downtown specific plans to improve multi modal connectivity in the core of the City.
TRANSIT, PARATRANSIT AND RAIL
Transit Public transportation in the City of Palm Springs is provided by SunLine Transit Agency, a joint powers authority created by the nine cities of the Coachella Valley, and the County of Riverside. Five routes currently serve the City of Palm Springs. SunDial, operated by SunLine, provides on-demand curb-to-curb paratransit service to qualifying persons (e.g., seniors and disabled) within three-quarters of a mile on either side of SunLine bus routes. Regional bus service is provided by Greyhound, which has a bus depot located on North Indian Canyon Drive near Amado Road.
Paratransit The Americans with Disabilities Act (ADA) requires all public transit operators to provide a paratransit (door-to-door) service to persons whose disabilities prevent them from using accessible fixed-route public transit. Paratransit services are transportation services such as carpooling, vanpooling, taxi service, and dial-a-ride programs. The Desert Health Car service is available to transport

CIRCULATION ELEMENT
seniors to the City’s senior centers, as is SunLine’s SunDial curb-to-curb paratransit service.
Rail Amtrak provides regional rail and bus service in the City. The North Palm Springs Amtrak train station is located west of Indian Canyon Drive just south of I-10. Palm Springs is currently a stop on Amtrak’s Sunset Limited service between Los Angeles and New Orleans. However, the train is not designed for commuters. Amtrak Thruway connecting service bus stops are located in Downtown Palm Springs on Indian Canyon Drive and near the Palm Springs Airport on East Tahquitz Canyon Way. The California Department of Transportation and Riverside County Transportation Commission are proposing a new Intercity Rail Route from Los Angeles to the Coachella Valley. The service would run from Los Angeles to Palm Springs, Palm Desert, and Indio in the Coachella Valley. Union Pacific also provides freight service along the rail line through Riverside County; currently, it runs up to 50 freight trains per day and that number will steadily increase. Because increased passenger service is desired in this area, it will become progressively more important to ensure the conflicts between freight and passenger trains and the local transportation system are addressed.
GOAL CR4:
Reduce the City’s dependence on the use of single-passenger
vehicles by enhancing mass transit opportunities.
Policies CR4.1 Support the delivery of improved regional transit services to and within the City. CR4.2 Continue to coordinate with SunLine Transit Agency and other regional transit agencies to address the need for the expansion or readjustment of bus routes, including express routes valleywide. CR4.3 Continue to coordinate with SunLine Transit Agency to establish or modify bus stop locations to provide
Page 4-28 Palm Springs 2040 General Plan
adequate access for local residents to destination places, such as Downtown, the airport, or the Convention Center. Coordinate improvements to existing and new bus stop locations including aesthetic bus shelters. CR4.4 Continue working with CVAG to achieve a regional transportation strategy that coordinates physical improvements, transportation systems management, transportation demand management, public transit, and issues of development that affect circulation. CR4.5 Work with the Riverside County Transportation Commission and Amtrak to provide increased passenger rail service to, and stopping in, Palm Springs and commuter rail, including high-speed rail concepts between Los Angeles and Phoenix. CR4.6 Pursue viable opportunities to partner with transit agencies, private shuttles, or Transportation Network Companies, to provide transportation options to the Downtown, hotels, museums, key activity centers (Convention Center, airport, etc.), particularly during special events.
GOAL CR5:
Provide improved mobility for City residents to access local
services.
Policies CR5.1 Support the implementation of local transit services for all residents with priority for the disadvantaged, including the elderly, handicapped, those with low incomes, and the temporarily disabled. CR5.2 Continue to encourage SunLine Transit Agency to provide bicycle racks on its vehicles. CR5.3 Require the construction of bus turnouts at bus stops on major and secondary thoroughfares to reduce congestion on the adjacent public street and to provide for greater overall traffic safety. The City should work with SunLine Transit Agency to determine which bus stop locations warrant bus turnouts and to address safety concerns that
Palm Springs 2040 General Plan Page 4-29
CIRCULATION ELEMENT
may arise at bus stops located throughout their service area. CR5.4 Encourage SunLine Transit Agency to periodically undertake studies of local public transportation needs to identify the most efficient and cost-effective manner to provide services, including shuttle services, medical transit service, and a centralized information location that promotes services available to the public. CR5.5 In consultation with the SunLine Transit Agency, require construction of attractive and protective bus shelters with complete route and schedule information, and other amenities, such as tourist information to promote transit ridership, at existing and new bus stop locations. CR5.6 Support and maintain sidewalk infrastructure to provide connectivity to transit facilities. CR5.7 Support a system of freight movement that minimizes impacts on residents and motorists. CR5.8 Encourage greater use of alternative fuel vehicles, including compressed natural gas, electric, hydrogen and other fuel sources. CR5.9 Explore opportunities for local shuttle circulator transit services in coordination with SunLine Transit Agency.

RECREATIONAL TRAILS AND BIKEWAYS
Recreational Trails Recreational trails are an important resource to the City of Palm Springs; they are a large part of the tourist draw to the community and they reflect the city’s history, both tribal and early European-American settlement and movement. Over 80 miles of recreational trails provide opportunities for biking, hiking, equestrian, backpacking and four-wheel drive activities. Figure 4-4, Bikeways and
Recreational Trails, shows the numerous recreational trails that extend through the San Jacinto and Santa Rosa Mountain areas, in addition to the City’s bike trails system. A comprehensive inventory and mapping of the trails in the San Jacinto and Santa Rosa Mountains have been developed through a cooperative partnership of the Bureau of Land Management–Palm Springs, South Coast Resource Area; U.S. Forest Service–San Jacinto Ranger District; Riverside County; Coachella Valley Trails Council; Agua Caliente Band of Cahuilla Indians; Coachella Valley Cycling Association; and Desert Riders. The Palm Springs Aerial Tramway provides access to trails located in the Mount San Jacinto State Park. The park covers an area of 13,000 acres and offers approximately 54 miles of hiking trails. The tramway starts in Chino Canyon on the north end of Palm Springs and takes passengers from Valley Station at 2,643 feet elevation to Mountain Station at 8,516 feet elevation.
Bikeway Classifications Off-street bikeways in exclusive corridors can be effective in providing new recreational opportunities and desirable commuter routes. On-street bikeways can enhance safety and convenience, especially in conjunction with other commitments such as: elimination of parking or increasing roadway width, elimination of surface irregularities and roadway obstacles. The designation of bikeway routes can help minimize potential roadway conflicts and can establish bicycle traffic as a priority in these areas.
Carl Lykken Trail is one of several hiking
trails located in the mountains adjacent to
the City.
Palm Springs 2040 General Plan Page 4-31
CIRCULATION ELEMENT
Figure 4-4 shows the location of existing and proposed bikeways in the City. The City has approximately 14 miles of Class I, 10 miles of Class II, and 35 miles of Class III bikeways. The State of California (and the City of Palm Springs) uses the following bikeway classifications.
Class I (Bike Path or Trail). Off-street bikeways that provide a completely separate right-of-way for the exclusive use of bicycles and pedestrians with crossflow by motorists minimized. The bike path area is physically separated from auto traffic or entirely outside the road right-of-way, and measures a minimum of 8 feet in width for two-way bicycling. Pedestrian paths are characterized by sidewalks or similar rights-of-way shared by cyclists and pedestrians that measure 12 feet wide, of which 8 feet will be designated for pedestrians and 4 feet will be designated for cyclists.
Class II (Bike Lane). Unprotected bikeways defined by a stripe on the roadway. A minimum 4-foot-wide lane within the roadway designated for one-way bicycle traffic.
Class III (Bike Route). Unprotected on-street bikeways sharing the roadway with vehicular traffic. Typically characterized as any type of bikeway, including streets signed as bikeways, that offers no other specific lane or other accommodation for bicycles.
Class IV (Separate Bikeway). Protected on-street bikeways defined by linear and vertical separation between the bike lane and vehicle lane. Separation may include but is not limited to grade separation, flexible posts, or on-street parking. A minimum of 5-foot-wide lane for one-way bike traffic and 2-foot-wide for separation. The City bicycle plan refers to these facilities as mixed use bike routes. In addition to the City’s bikeway design standards, the CVAG Active Transportation Design Guidelines and the State of California Highway Design Manual provide requirements for Bikeway Planning and Design that should be considered as new bikeways are designed and developed in Palm Springs. Figure 4-4 shows existing and proposed bikeways and recreational trails. Both facilities are off-street and typically serve multiple modes of travel such as bikes and pedestrians. Recreational trails
Page 4-32 Palm Springs 2040 General Plan
may be located partially or completely within the City of Palm Springs but generally provide access to remote and undeveloped recreational areas. Class I bikeways provide access to developed areas within and around the City of Palm Springs.

GOAL CR6:
Establish the City as the premier provider of recreational trails
and bikeways in the Coachella Valley.
Policies CR6.1 Maintain a program regarding nonmotorized
transportation facilities, including those for bicycles and pedestrians. CR6.2 Provide improved signage to direct residents and visitors to the City’s trail system. CR6.3 Ensure new development applications establish access or safe connections to public trails and trailheads as specified by the applicable specific plan. CR6.4 Utilize bicycle and hiking trails as a means of providing recreational and educational experiences by connecting to various parks and public facilities throughout the City. CR6.5 Seek optimum linkage of existing and planned for bikeways to parks, recreation centers, and other recreational open space. CR6.6 Maintain widths, surfaces, and general maintenance of streets in a manner that will ensure the safety of the cyclists using them. CR6.7 Provide bikeways with appropriate traffic control devices. CR6.8 Encourage proper design and maintenance of facilities and appropriate signing to ensure the safe use of the bikeway and trail systems. CR6.9 Promote and enhance bicycling and hiking opportunities to support local tourism. CR6.10 Incorporate provisions within the Zoning Ordinance requiring private developers to construct recognized bikeways that abut developable property. CR6.11 Evaluate the need for and the feasibility of developing new bikeways and recreational paths (or improving to Class I standards) as the City continues to grow.
Additional goals and policies
related to pathways and bikeways
can be found in the Recreation,

A nonmotorized transportation
facility may be part of a roadway
(such as a shoulder) or it may be
separated from roadway traffic for
exclusive non-motorized use (such
as a bike path or sidewalk).
Page 4-36 Palm Springs 2040 General Plan
CR6.12 Recognize the importance of the City’s bikeway system as a major transportation, not solely recreational, network. CR6.13 Maintain design standards for the development of various types of bikeways and related improvements—e.g., parkways, bridges, rest stops—that may be necessary to implement the City’s bikeway network. CR6.14 Coordinate with CVAG, adjacent cities, and affected agencies while planning for new trails, especially in areas adjacent to the Whitewater Wash and Cathedral City. CR6.15 Improve pedestrian and bicyclist connectivity to regional trails like CV Link. CR6.16 Provide bike racks and other bicycle amenities throughout the City to encourage bicycle use as an alternative to vehicular use.
PEDESTRIANS Pedestrian activity is an important part of the City’s recreational lifestyle. Pedestrian facilities such as walkways, bridges, trails, crosswalks, signals, benches, and shade canopies are a critical component of the nonmotorized transportation network in Palm Springs. In areas where pedestrian facilities are present, people will be much more likely to make short trips by walking instead of by automobile. Pedestrian walkways help to link educational facilities to City parks and can help create a critical lifeline between the retail shops Downtown and the City’s resort amenities such as the Convention Center, casino, and hotels.
GOAL CR7:
Create a pedestrian experience that is attractive to both
residents and visitors.
Policies CR7.1 Provide a safe and comfortable environment for pedestrians. CR7.2 Provide a welcoming atmosphere for visitors by providing safe and comfortable multi modal and parking facilities Downtown.
Palm Springs 2040 General Plan Page 4-37

CR7.3 Improve pedestrian links throughout the city and from surrounding residential areas to Downtown. CR7.4 Utilize traffic calming measures in accordance with the City’s Neighborhood Traffic Calming Program in appropriate locations to improve pedestrian safety and comfortability, slow traffic, and help reduce noise impacts on adjacent uses. CR7.5 Ensure that appropriate pedestrian facilities are provided as a component of new development, including ADA compliant sidewalks and crosswalks where appropriate. CR7.6 Maintain design standards for the construction of new pedestrian facilities and related improvements.
PARKING Vehicular parking is a necessary consideration of any land use. It is essential that new development and projects undergoing redevelopment analyze the parking demand they generate. Due to the location of residential uses in close proximity to the commercial uses Downtown, there are many opportunities for potential parking conflicts or overflow commercial parking on residential streets. On-street parking and parking structures need to be carefully integrated into the existing urban fabric so they do not detract from the aesthetic quality and character of commercial and residential areas.
GOAL CR8:
Develop a system of parking facilities and operations that serve
current and future commercial and residential uses and
preserve the quality of life in residential neighborhoods.
Policies CR8.1 Require sufficient parking to serve each use, including employee and visitor parking needs. CR8.2 Locate surface parking lots to the rear of businesses fronting main streets. Surface parking lots directly fronting onto main streets interrupt the continuity of

CR8.4 Evaluate the use of parking districts to resolve preexisting deficiencies. CR8.5 Encourage the development and use of common parking facilities versus individual on-site parking facilities. CR8.6 Explore the development of a valet parking program to enhance parking access and availability Downtown. CR8.7 Design parking structures in the Downtown to complement the scale, aesthetic, and activity levels of adjacent buildings and uses. CR8.8 Encourage private developments to provide parking in excess of that required by the Municipal Code for lease to other businesses with parking deficiencies. CR8.9 Encourage the redesign of existing parking lots if additional spaces can be created as well as spaces for bicycles and motorcycles. CR8.10 Provide appropriate and consistent signage to direct motorists to public and private parking areas. CR8.11 Utilize parking fees and on demand pricing to promote vehicle turnover and increase parking availability in Downtown while helping to encourage carbon free/reduced alternative transportation such as walking, bicycles, public transportation, and ride share. CR8.12 Encourage businesses to implement innovative approaches to employee parking such as the development of satellite parking areas that allow employees to park at remote locations outside of Downtown and provide shuttle access to the workplace if the parking site is located more than one-quarter mile from the workplace to make parking spaces Downtown more available to customers and visitors.
Parking District:
A district established to manage
parking issues in a particular area.
Parking districts can distribute the
revenue from parking meters and
other fee programs to implement
solutions to parking problems.
Such solutions may include the
creation or maintenance of parking
lots, parking structures, valet
parking, parking/transportation
signage, landscaping,
maintenance, and security.
Parking districts can also impose
parking time limits and implement
programs to manage employee
versus visitor parking.

CIRCULATION ELEMENT
AVIATION AND HELIPORT FACILITIES Three airports serve the Coachella Valley: Palm Springs International Airport, Desert Resorts Regional Airport (Thermal Airport), and Bermuda Dunes Airport. Palm Springs International, the largest of the three, provides connections to many key points throughout the United States and Canada. Air freight is also handled at the airport. The City is currently undergoing an update to the airport master plan for the Palm Springs International Airport. That study’s initial findings are that the airport is expected to double in airport use; increasing from approximately three million annual passengers (MAP) to a 2045 forecast of 6.5 MAP. As a vital economic asset to the City, access to the airport must be maintained and improved to meet growing passenger demands. As passenger activity continues to grow, transportation services must keep pace with that expansion. Currently, SunLine Route 2 provides public transportation service to the airport. In addition, several resorts and hotels offer courtesy shuttle service to the airport. Amtrak Thruway bus service is also available. Additional transportation services including limousine, taxi, shuttle, and disabled and senior services are available at the airport. As the airport expands to satisfy air passenger demands, additional public transportation services should be considered to serve resident and visitor air passengers. Additional courtesy shuttles could be considered or integrated to provide efficient service to popular destinations, such as the Downtown area. Heliport access in Palm Springs is limited to medical evacuation flights traversing to and from the Desert Regional Medical Center heliport and the Palm Spring International Airport.

GOAL CR9:
Maintain and operate safe, efficient, economical, and
environmentally responsible airport and heliport facilities in
the City.
Policies CR9.1 Ensure airport and heliport operations in Palm Springs are consistent with the Federal Aviation Regulation Part 150 Noise Compatibility Study, as amended from time to time and consider the provisions of the Palm Springs Airport Land Use Compatibility Plan prepared by the Riverside County Airport Land Use Commission. CR9.2 Establish the City’s commercial streets as the principal helicopter flight corridors and require that helicopter takeoff and landing patterns be limited to commercial areas. CR9.3 Require that helicopters utilizing City airspace fly in compliance with Federal Air Regulations (FAR) Part 91 rules. CR9.4 Establish multi modal circulation linkages (buses, trams, bicycle infrastructure, etc.) to and from the airport to relieve parking and traffic loads at the airport.
UTILITIES
Water Supply and Distribution Systems The Coachella Valley Water District (CVWD), the Desert Water Agency (DWA), and Mission Springs Water District (MSWD) provide water to the City of Palm Springs. These water agencies prepare an Urban Water Management Plan every five years, which identifies historic and projected water usage, identifies existing and future water supply sources, describes purveyors’ demand management programs, and sets forth a program to meet water demands during normal, dry, and multiple dry years. Three groundwater subbasins—Whitewater River, Mission Creek, and Indio—serve Palm Springs and its planning area. The Whitewater River, the largest basin, contains 28 million acre-feet and extends 70 miles from the junction of Highway 111 and I-10 to

CIRCULATION ELEMENT
the Salton Sea. The Whitewater River is recharged by flows from the San Gorgonio Pass area, normal seasonal rainfalls, snowmelt, and surface water from various creeks. However, inflow is limited. Therefore, to ensure that adequate water is available, the Coachella Valley water agencies rely on two sources of imported water—the Colorado River and the State Water Project (SWP). CVWD’s entitlement to Colorado River water is firmly established at 330,000 acre-feet. Through contracts with MWD and the SWP, CVWD and DWA have allocations for water supply totaling approximately 194,100 acre-feet. This supply is specifically used to recharge the groundwater basin. As part of the 2019 Exchange Agreement between MWD and CVWD, water from the MWD pipeline is released into 19 recharge ponds at Windy Point, where it percolates into the Whitewater Subbasin. This agreement is intended to ensure adequate water supplies through the year 2035. Deliveries of SWP water, however, are not guaranteed. Since most of California’s annual precipitation falls in the winter and early spring, most of the water supply is certain by this time. However, runoff in the late fall remains somewhat variable as the next year’s runoff season begins. A drier than forecasted fall can result in not meeting end-of-year reservoir storage targets, which means less water available in storage for the following year. In 2019, the California Department of Water Resources modelled that a single dry year SWP water supply allocation may be 7 percent below the water supply allocation for a typical year. The DWA provides water to Palm Springs, parts of Desert Hot Springs and Cathedral City, and surrounding unincorporated areas. Groundwater currently comprises approximately 95 percent of the water DWA provides to its customers, with the remainder being surface water from mountain streams. The groundwater is obtained from the Whitewater River Subbasin which underlies the northwest Coachella Valley from Whitewater in the northwest to the area of Bermuda Dunes in the southeast. The CVWD, based in Coachella, bears responsibility for ensuring reliable water supplies for the Coachella Valley, including portions of Palm Springs, and managing groundwater in the subbasins beneath the Valley. By 2045, groundwater is estimated to account for approximately 79 percent of DWA -supplied water. Water is recharged into the subbasin from two sources: local stormwater and imported water. The Agency and District purchase entitlements to water from the State Water Project. However, as
Page 4-42 Palm Springs 2040 General Plan
there is no aqueduct connecting the Coachella Valley to the State Water Project, the District and Agency trade their water entitlements from the State Water Project to the Metropolitan Water District of Southern California in exchange for imported water from the Colorado River. Recharge of imported water into the Whitewater River Subbasin began in 1973. In 2002, the Agency and District also began recharging imported water into the Mission Creek Subbasin, which underlies the area surrounding Desert Hot Springs and North Palm Springs.
Wastewater Treatment and Collection The City contracts with Veolia Water North America to operate a comprehensive wastewater treatment program, including a City-owned, 10.9 million gallon per day (mgd) trickling filter wastewater treatment plant, five pump stations, 225 miles of sewer collection pipelines, six percolation ponds, and a biosolids disposal program. The treatment plant currently accommodates approximately 6.5 mgd of sewage flow. Recycling wastewater is an important water conservation strategy, because it reduces the amount of potable water used for irrigation. DWA operates a wastewater recycling facility. The City provides primary and secondary treated domestic sewage to DWA, who then provides tertiary treatment. The recycled water is then used to irrigate public facilities such as the Tahquitz Creek Golf Course, DeMuth Park, and the Mesquite Golf Course.
Storm Drainage Systems The Palm Springs Master Drainage Plan covers approximately 26.5 square miles, and consists of moderately flat valley terrain sloping generally to the east. Steep mountainous terrain dominates the westerly portion of the drainage area. The purpose of the plan centers on the following points:
Determination of the quantity and points of concentration of storm runoff in the area
Preparation of a drainage boundary map
Determination of the location, size, and capacity of the proposed drainage structures
Investigation of alternatives to select the plan with the most sound economics and engineering

Solid Waste Palm Springs Disposal Services provides solid waste disposal service to the City of Palm Springs and sphere of influence areas. According to the California Integrated Waste Management Board, a total of 81,369 tons of solid waste was produced by Palm Springs in 2021. Palm Springs Disposal Services transports solid waste from Palm Springs to Edom Hill Transfer Station in Cathedral City. Edom Hill is permitted to receive 3,500 tons of waste per day as a transfer station. From Edom Hill, waste is trucked to Lamb Canyon Sanitary Landfill in Beaumont, approximately 24 miles west of Palm Springs. Lamb Canyon Landfill is permitted to accept 5,000 tons of waste per day. The remaining capacity of the landfill is approximately 19,242,950 cubic yards of waste and its estimated closing date is 2032. Palm Springs Disposal Services uses Badlands Landfill in Moreno Valley as an alternate disposal site. Badlands is permitted to receive 5,000 tons of waste per day and has a remaining capacity of approximately 7,800,000 cubic yards. Its estimated closing date is 2059. On December 9, 2021, the Palm Springs City Council passed a new ordinance which requires organic waste collection services to all residents in accordance with Senate Bill (SB) 1383. This includes collection of yard waste and food waste. Organic waste collection was already available to commercial establishments. Residential organic waste service began on October 1, 2022.
Electricity Southern California Edison (SCE) currently provides service to the City and areas within the Sphere of Influence. SCE currently maintains major transmission lines within the City along their normal distribution system. Because of the current supply capacity of SCE, adequate electrical capacity is anticipated for the City of Palm Springs. Desert Community Energy, a not-for-profit publicly managed electricity provider, began supplying electricity to the City of Palm
Page 4-44 Palm Springs 2040 General Plan
Springs in April 2020. Desert Community Energy is a Community Choice Energy program, which purchases power resources on behalf of the electricity customers in its jurisdiction to control costs, offer more renewable energy options, and reduce greenhouse gas (GHG) emissions. Under this system, Desert Community Energy purchases electricity, while SCE continues to deliver electricity, maintain infrastructure, and handle billing and repairs.
Natural Gas The Southern California Gas Company (Gas Company) provides natural gas service to Palm Springs’ citizens and business industry within the City and sphere of influence. The availability of natural gas service is based upon present conditions of gas supply and regulatory policies. As a public utility, the Gas Company is under the jurisdiction of the Public Utilities Commission and federal regulatory agencies. Should these agencies take any action that affects gas supply, or the conditions under which service is available, gas service would be provided in accordance with revised conditions.
Tele communications There are currently adequate telecommunication facilities available to serve the needs of the City. Data transmission, connectivity to the internet, and other wired and wireless data transmission systems are provided by a variety of carriers and providers. Currently, broadband internet service is provided by Spectrum, Frontier, Viasat, T-Mobile Home Internet.
GOAL CR10:
Provide adequate and safe utility systems and facilities to
support the City’s existing and proposed land uses.
Policies CR10.1 Require utility improvements where existing systems are deficient. CR10.2 Coordinate public infrastructure improvements through the City’s Capital Improvement Program. CR10.3 Encourage the shared use of major transmission corridors and other appropriate measures to minimize

CR10.4 Continue and expand existing programs for the upgrade of storm drainage systems where they are deficient, using public or private funds. CR10.5 Require that new development be contingent upon the project’s ability to secure appropriate infrastructure services. CR10.6 Require developers of new projects to pay for the costs of construction and expansion water, sewer/wastewater, storm drainage improvements and other public utilities necessitated by that development. CR10.7 Require developers to notify utility agencies of their intent to develop a site early in the development process to provide sufficient time to plan for necessary capital improvements. CR10.8 Update the Sewer System Master Plan as needed to accommodate the demands of new and existing development. CR10.9 Monitor sewer flows on a regular basis to aid in the development of construction schedules. CR10.10 Require new projects to connect with the City’s storm/sewer system unless a hardship can be demonstrated. If septic systems must be used require installation of septic systems to meet State Water Resources Control Board Standards. CR10.11 Monitor and reassess rates for sanitation/wastewater connection and service. This assessment should reflect the costs of service and improvements and be equitably allocated to users according to demands. CR10.12 Participate in the annual review of the Desert Water Agency, Mission Springs Water District, and Coachella Valley Water District Water System Master Plan to evaluate how it is consistent with the City’s General Plan and approved projects.

PALM SPRINGS CIRCULATION ELEMENT | DRAFT IMPLEMENTATION PROGRAMS
September 2024
This section serves as a working checklist of implementation programs for City staff and local decision makers to ensure that the General Plan
vision is realized. The following table of Implementation Programs lists specific actions that should be pursued to implement each goal and policy
in the City’s General Plan. An implementation program is an action, procedure, program, or technique that carries out goals and policies.
Implementation measures are comprehensive in nature, encompassing amendments of existing and preparation of new plans, ordinances, and
development of design standards; administration of City procedures and development review and approval processes; and interagency
coordination.
For each action, a recommended timeframe for completion is noted and the responsible City department is listed. The timeframes are
delineated as follows:
Ongoing: Actions that continue or are periodically implemented through the life of the General Plan
Short: 1-5 years
Mid: When resources become available, but prioritized after 5 years
Long: 10 years or more
The described programs and actions are intended to inform and guide the development of the City’s annual budget. During that time, City staff
will review and prioritize the level of expenditure necessary to carry out the prescribed action and program. Completion of a recommended
implementation program will depend on a number of factors such as citizen priorities, finances, and staff availability.
To enable Palm Springs’ General Plan to serve its purpose effectively, the list of programs and actions need to be reviewed, maintained, and
implemented in a systematic and consistent manner. At a minimum, the programs and timeframes described in this chapter should be
comprehensively reviewed and updated at least once every five (5) years to reflect available fiscal resources, community needs, and priorities.
Revisions to these shall not constitute an amendment of the General Plan, provided that they are consistent with the Vision Statement and carry
out its goals and policies. As such, future revisions to this Implementation Plan will not necessitate environmental review to conform to
California Environmental Quality Act (CEQA) requirements, as each item described in this Plan will require subsequent action and evaluation.

Executive Summary
PROPOSED GENERAL PLAN UPDATE
Fehr & Peers has completed a transportation analysis for the proposed General Plan Update in the City of
Palm Springs, California. The proposed City of Palm Springs General Plan Update (the project) includes
residential, commercial, industrial, and mixed-use land use designations. In total, the General Plan land use
proposes net increase of approximately, 25,773 households and 30,081 jobs.
SCOPE OF STUDY
Roadway segments, intersections, and multi-modal transportation facilities such as pedestrian, bicycle, and
transit were all considered in this transportation impact assessment study. The study area included major
roadway facilities and critical intersections in the City of Palm Springs. The City of Palm Springs Vehicle Miles
Traveled (VMT) VMT were evaluated.
ANALYSIS METHODOLOGIES
The Highway Capacity Manual 6th Edition methodology was used for roadway segments and intersections
CEQA impacts were assessed using the City of Palm Springs adopted Vehicle Miles Traveled (VMT) threshold
of significance. The Riverside County Model (RIVCOM) was used to develop future year traffic volume
forecasts, and to evaluate VMT.
RESULTS
This transportation impacts assessment was done under the framework of CEQA. VMT per Service
Population decreased, which indicates that travel becomes more efficient in Palm Springs with the
implementation of the updated General Plan. Therefore, the impact to transportation is considered less
than significant under CEQA.
All other items covered in Appendix G of the California Environmental Quality Act (CEQA) Guidelines (14
CCR 15000 et seq.) were determined to have less than significant impacts.
The assessment found the following roadways included segments that operated below the established LOS
standard with the buildout of the General Plan:
· Highway 111
· Sunrise Way
· Gene Autry Trail
· Ramon Road
· E Palm Canyon Drive
These segments are projected to operate “at capacity” at LOS E or “over capacity” LOS F with the buildout
of the General Plan. All identified segments were projected to operate at LOS E or F in the previously
approved 2007 General Plan.
The assessment found the following intersections operated below the established LOS standard with the
buildout of the General Plan:
· Vista Chino at Highway 111
City of Palm Springs General Plan Update
May 2023

· Vista Chino at Sunrise Way
· Vista Chino at Farrell Dr
· Alejo Road at Indian Canyon Drive
· Tahquitz Canyon Way at Indian Canyon Drive
· Ramon Rd at Sunrise Wy
· Ramon Rd at Farrell Dr
· E Camino Parocela at Indian Canyon Dr/S Palm Canyon Dr
· E Palm Canyon Dr at Sunrise Wy
These segments are projected to operate “at capacity” at LOS E or “over capacity” LOS F with the buildout
of the General Plan. All identified intersections were projected to operate at LOS E or F in the previously
approved 2007 General Plan, with the exceptions of Vista Chino at Highway 111, which was projected to
operate at LOS D in the PM peak hour under the 2007 General Plan and is projected to operated at LOS E
in the PM peak hour under this proposed General Plan update.

1. Introduction
Fehr & Peers has completed the transportation impact analysis for the proposed Palm Springs General Plan
Update in the City of Palm Springs, California. This report summarizes the methodology, findings and
conclusions of the analyses, including identification of recommended mitigation measures necessary to
maintain consistency with the goals and policies of the proposed General Plan.
This chapter outlines the geographic scope of the transportation impact analysis, including the study area.
1.1 Project Description
The proposed City of Palm Springs General Plan Updated consists of the buildout of residential and
nonresidential development within the City and changes to the City’s circulation system. The General Plan
update assumes a growth of 25,773 households and 30,081 jobs.
1.2 Analysis Scenarios
To identify potential significant project impacts, Fehr & Peers analyzed the effects of traffic under the
following three scenarios:
Existing Year (2019) Conditions – Roadway volumes were purchased from a big data provider,
Streetlight Data. The data was collected using anonymized and aggregated GPS and cell phone
data. The volumes represent the average daily traffic on Tuesdays-Thursdays throughout 2019 while
schools were in session. This data was compared to historic counts provided by the City of Palm
Springs and the Coachella Valley Association of Governments (CVAG).
Cumulative Year (2045) No Project Conditions – Consists of forecasted volumes to Year 2045 based
on growth and travel forecasts contained in the Riverside County Model (RIVCOM). This scenario
assumes minimal change in existing land use for the City of Palm Springs.
Cumulative Year (2045) Plus Project Conditions – Consists of forecasted volumes to Year 2045 based
on the growth and travel forecasts contained in the Riverside County Model (RIVCOM) and the land
use projects proposed by the General Plan Update.
Roadway segment and intersection Level of Service (LOS) is reported for these analysis scenarios; however,
this information is not used to identify significant project impacts. The City of Palm Springs adopted CEQA
thresholds consistent with Senate Bill 743, which identified that Vehicle Miles Traveled (VMT) would be used
to evaluate significant transportation impacts under CEQA.
1.3 Study Area
The study area of this analysis includes roadway segments and intersections in the City of Palm Springs that
are anticipated to be affected by the proposed General Plan. The following lists define the study area:

2. Analysis Methodologies
The transportation impact analysis methodology includes a combination of quantitative and qualitative
evaluations of the roadway, bicycle, pedestrian, and transit components of the transportation system. All
analysis presumes that future background travel conditions remain relatively constant and do not account
for potential changes associated with disruptive trends such as increased use of transportation networking
companies (TNCs), which include Uber and Lyft, internet shopping, other internet related activities,
automated vehicles (AVs), and micro-transit services.
2.1 Vehicle Miles Traveled
RIVCOM was used to forecast roadway segment volumes and estimate existing and future VMT. This model
is consistent with the 2020 SCAG RTP/SCS; it has a base year of 2018 and a forecast year of 2045.
The 2045 roadway network and land use inputs were revised to reflect the new General Plan conditions for
the Cumulative Year Plus Project analysis.
2.2 Level of Service
Level of service was evaluated for roadway segments and intersections in the City of Palm Springs to ensure
consistency with adopted General Plan policies. For both segments and intersections, methodology
consistent with the Highway Capacity Manual (HCM) 6th Edition (Transportation Research Board (TRB), 2017)
was followed.
The volume-to-capacity (V/C) ratio is reported for each roadway segment and intersection. After the
quantitative V/C or delay estimates are complete, the methodologies assign a qualitative letter grade which
represents the operations of the intersection. These grades range from level of service (LOS) A (minimal
delay) to LOS F (excessive congestion). LOS E represents at-capacity operations.
2.3 Regulatory Setting and Significance Criteria
The significance criteria used to evaluate the project impacts to transportation are based on the City of Palm
Springs Traffic Impact Analysis Guidelines (July 2020) and the CEQA Appendix G Environmental Checklist
(2021). Specific criteria to be used for identifying potential transportation impacts are:

Table 1: Significance Criteria
Impact Categories CEQA Significance Criteria
Plan Conflict The project would conflict with a program, plan, ordinance or policy addressing the
circulation system, including transit, roadways, bicycle and pedestrian facilities.
VMT Impacts¹ The project would result in a VMT-related impact as described below
Hazard Impact
The project would substantially increase hazards due to a geometric design feature
(e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm
equipment).
Emergency Access Impact The project would result in inadequate emergency access.
Note: 1. Refer to Table 2
Source: AEP, 2021
For plan conflicts addressing the circulation system, a review of transit, roadways, bicycle and pedestrian
facilities are provided in Chapter 3. For VMT impacts, the City’s guidelines include detailed thresholds for
project and cumulative conditions as shown in Table 2. In this case, the Project proposes the addition of
25,773 households and 30,081 jobs.
Table 2: VMT Significance Thresholds
Impact Categories Significance Thresholds
Project Level Impacts
The baseline project-generated VMT per service population exceeds the City of
Palm Springs General Plan Buildout VMT per service population, or
The cumulative project-generated VMT per service population exceeds the City of
Palm Springs General Plan Buildout VMT per service population
Cumulative Impacts
The cumulative link-level boundary VMT per service population within the City
boundary increases under the plus project condition compared to the no project
condition.
Note: 1. Service population is typically defined as population plus employment. For campuses, service population is defined as
population plus employment plus students. The transportation consultant shall not double count resident students twice in
this evaluation (i.e., shall not count students that also live on campus).

2.4 Existing Vehicle Miles Traveled Analysis
The latest version of RIVCOM was used to estimate the existing VMT per Service Population for the City of
Palm Springs.
VMT was estimated using the Origin/Destination (OD) method. This was completed by multiplying the OD
trip tables and the final assignment skim matrices. The OD tables provided the number of trips between
each Traffic Analysis Zone (TAZ), and the skim matrices provided the distance on the roadway network, or
7
trip length, between each TAZ. The full length of all trips with an origin or destination in the TAZ
representing the City of Palm Springs were used to estimate the City VMT.
VMT was also estimated using the Production/Attraction (PA) method. This was completed by summing all
weekday VMT generated by trips with at least one trip end in the study area. The PA method is completed
after the fourth (out of five) loops of assignment in the travel demand model, while trips are still tracked by
trip purpose. Productions and attractions are converted from person trips to vehicle trips for the purposes
of calculating VMT. PA matrices do not include trips that have one trip end outside of the model boundary
(IX-XI trips) and, therefore, do not include those trips in the VMT estimates. Home-based PA VMT represents
VMT generated that starts or ends at a home in the City of Palm Springs. Home-based-work PA VMT
represents all commute VMT generated by residents and employees in the City of Palm Springs.
The City of Palm Springs City Boundary and Sphere of Influence have both been provided. The Sphere of
influence and PA VMT performance are provided for informational purposes only, all impact conclusions
will be made based on OD VMT within the City’s boundaries.

This section evaluates existing roadway segment operations using Chapter 16 of the Highway Capacity
Manual (HCM) 6th Edition (Transportation Research Board (TRB), 2017). Roadway segments are evaluated
using daily service volumes, which may be used to identify how much additional roadway capacity is
available. The methodology assigns a qualitative letter grade range from C (stable operation) to E (unstable
operation and congestion) that represents the operations of the roadway, as presented in Table 4Error!

provider, StreetLight Data. The data was collected using anonymized and aggregated GPS and cell phone
data. The volumes represent the average daily traffic on Tuesdays-Thursdays throughout 2019 while
schools were in session. This data was compared to historic counts provided by the City of Palm Springs
and the Coachella Valley Association of Governments (CVAG). The StreetLight volumes were adjusted
based on historic trends and used to evaluate the existing roadway segment LOS, which is presented

3.2 Existing Intersections
As noted in the discussion of roadway segments, at the time of completing this assessment, traditional
traffic counts were not considered reliable due to the effects of the COVID-19 pandemic. Intersection
turning movement counts were compiled from recent traffic studies and data the City and CVAG had
collected. The counts were then grown based on historic trends observed in the StreetLight data
comparison described above to represent intersection volumes as of 2019.
3.2.1 Intersection Level of Service
Signalized intersections were analyzed using the Highway Capacity Manual (HCM) 6th Edition
(Transportation Research Board, 2017) methodology. The HCM 6th Edition methodology for signalized
intersections estimates the average control delay for vehicles at the intersection.
For unsignalized study intersections methodologies consistent with HCM 6th Edition were utilized to
evaluate intersection operations. The HCM 6th Edition methodology for unsignalized intersections
estimates the average control delay for vehicles at all-way stop-controlled intersections and estimates the
worst-case movement delay for side-street stop-controlled intersections.
Descriptions of the LOS letter grades for intersections are provided in Table 6 and LOS results are
provided in Table 7. The existing intersection turning movement counts in the City are shown on Figure
1.
All analysis was performed using the Synchro 11 software. Level of Service worksheets are provided in

3.3.3 Passenger Rail
Amtrak provides regional rail and bus service within the City of Palm Springs. The Amtrak station in Palm
Springs is located west of Indian Canyon Drive south of I-10 in the Northern Palm Springs region. The Sunset
Limited and Texas Eagle routes stop at the Palm Springs Amtrak Station, with one train in each direction
most days.
The Amtrak Thruway Bus provides a connection from the Palm Springs Amtrak Station and Palm Springs
airport and Fullerton Station to the Pacific Surfliner service.
3.4 Existing Bicycle Facilities
Currently, there are bike facilities along most corridors in Palm Springs.
3.4.1 Bicycle Facility Classifications
Bicycle facilities as described in the City of Palm Springs Bicycle Route Plan (2014) are classified as follows:
3.4.1.1 Class I
Referred to as a bike path, shared-use path, or multi-purpose trail. Provides for bicycle travel on a paved
right-of-way completely separated from any street or highway. Other users may also be found on this type
of facility.
3.4.1.2 Class II
Referred to as a bike lane. Provides a striped lane for one-way bicycle travel on a street or highway.
17
3.4.1.3 Class III
Referred to as a bike route. Provides for shared use with pedestrian or motor vehicle traffic.
3.4.1.4 Colored Bike Lanes
Colored bike lanes are bike lanes with an approved color in the Palm Springs Bicycle Route Design
Guidelines
3.4.1.5 Buffered Bike Lanes
Buffered bike lanes provide a painted area between the bike lane and either the travel lane or parking lane.
Double-buffered bike lanes provide a painted buffer on both the travel lane and parking lane. These bike
lanes may also be colored.
City of Palm Springs General Plan Update
May 2023
18
3.4.1.6 Cycle Tracks
Cycle tracks, also called protected bike lanes, provide a physical barrier between the bike lane and other
lanes. If there is on-street parking they are placed between the sidewalk and parking. Cycle tracks may be
one-way or two-way. They may also be at the level of the street, at the level of the sidewalk, or between the
two.
3.4.1.7 Type B Sharrows
Type B sharrows provide a more prominent shared lane marking than the standard shared lane marking.
This may be achieved through augmentation of the shared lane marking with side lines, a larger stencil,
more frequent placement, and/or paint underneath.
3.4.1.8 Shared Lane Marking Streets
Shared lane marking streets are simply streets with standard shared lane markings or “sharrows” to make
motorists alert for bicyclists, to train cyclists where to ride in the lane and to educate motorists of bicyclists’
rights to ride in the lane. These shared lane-marking streets will not have bikeway signs.
3.4.2 Bicycle Facility Locations
The existing bicycle facilities in the City are shown on Figure 2.
In addition to on-street bike facilities, the City includes a number of off-street trails, including the CV Link
trails between Ramon Road and Vista Chino Road.
The Coachella Valley Association of Governments Active Transportation Plan (ATP) published in 2016
provides the proposed bikeway projects for the City of Palm Springs, which can be found in Table 4-27 of
the ATP. New bikeways or improved are proposed on many roadways in the City, including:
Baristo Road
Amado Road
Ramon Road

3.5 Existing Pedestrian Facilities
Most of the major roadways through Palm Springs provide continuous sidewalks on both sides of the
road. Pedestrian facilities can be found at key corridors such as Gene Autry Trail between Vista Chino and
Ramon Road, and Sunrise Way between Vista Chino and Palm Canyon Drive.
Current pedestrian facilities provide sufficient sidewalk width for pedestrians with minimal sidewalk
damage. Curb ramps are typically provided within the City of Palm Springs. Some sidewalk gaps exist
throughout the City, particularly on residential streets and longa the frontage of vacant parcels.
The City of Palm Springs Citywide Traffic Calming Projects details the recently completed projects in May
2021 that aim to improve pedestrian safety through traffic calming. The following discusses improvements
to pedestrian facilities described in The City of Palm Springs Citywide Traffic Calming Projects:
South Palm Canyon Drive and La Verne Way –ADA ramps and crosswalks
South Palm Canyon Drive and Murray Canyon Way –ADA ramps and crosswalks
Toledo Avenue and La Verne Way –ADA ramps and crosswalks
Toldeo Avenue and Maricopa Drive –ADA ramps, and crosswalks
Rosa Parks Road and Tramview Road – ADA ramps, crosswalks, and speed cushions
West Racquet Club Road – Modified existing road diets
o Removed 6-inch diameter bollards
o Replaced with 2-inch diameter delineators
South Riverside Drive –Speed cushions and associated signage
Mesquite Avenue- Speed cushions and associated signage
The Coachella Valley Association of Governments Active Transportation Plan provides the proposed
pedestrian improvements for the City of Palm Springs, which can be found in Table 6-2 of the ATP. These
improvements include intersection level improvements such as enhanced crosswalks and countdown
signals, pedestrian lighting on Farrell Drive and Baristo Road, and new sidewalks on Baristo Road.

4. Impact Analysis
This chapter evaluates potential transportation impacts under Cumulative Plus Project conditions, with the
proposed buildout of the General Plan update.
3.2 Vehicle Miles Traveled
The RIVCOM model was modified to include the Project to evaluate its impacts. The addition of 25,773
households and 30,081 jobs were added to the appropriate City of Palm Springs and City of Palm Spring
Sphere of Influence TAZs to assess the Project generated VMT per Service Population.
Origin-Destination Project Generated VMT
VMT was estimated using the Origin/Destination method. This was completed by multiplying the OD trip
tables and the final assignment skim matrices. The OD tables provided the number of trips between each
TAZ, and the skim matrices provided the distance on the roadway network, or trip length, between each
TAZ. The full length of all trips with an origin or destination in the TAZ representing the City of Palm Springs
were used to estimate the project generated VMT.
Table 9: Project Generated Vehicle Miles Traveled
Cumulative (2045) No
Project
Cumulative (2045)
Plus Project
City of Palm Springs Daily OD VMT 3,790,685 5,489,376
City of Palm Springs Service Population 103,436 152,312
City of Palm Springs VMT/Service Population 36.65 36.04
Source: Fehr & Peers, 2022
As shown in Table 4, the Project generated VMT per service population does not exceed the City’s adopted
threshold. In fact, VMT per service population is forecast to decrease under general plan buildout conditions
(36.04) compared to the existing condition (39.04) and the future no project condition (36.65), indicating
that the population is expected to travel in a more efficient manner. The improvement in travel efficiency
is the result of people making fewer trips and traveling shorter distances due to increased availability of
active modes of transportation and better accessibility to destinations by all modes of transportation.
Boundary Method Cumulative VMT
The 2045 RIVCOM model was used to calculate the VMT Per Service Population for the City of Palm Springs
in the Cumulative condition.
23
The 2045 RIVCOM model was modified to include the Project to evaluate cumulative project effect on
citywide VMT under the Cumulative Plus Project condition. VMT was estimated using the boundary method.
This was completed by selecting all roadway segments in the SBTAM model within the City of Palm Springs
boundary and multiplying the number of trips on each roadway segment by the length of that roadway
segment.
Table 10: Cumulative Vehicle Miles Traveled
Future Year No Project (2045)
Cumulative VMT Per Service
Population
Future Year Plus Project (2045) Project Effect
on VMT Per Service Population
City of Palm Springs 7.75 7.44
Source: Fehr & Peers, 2022
As shown in Table 10, the Citywide VMT per Service Population under the “with project” condition does not
exceed the Citywide VMT per Service Population under the “no project” condition.
VMT Impact Conclusion
Overall, the analysis shows that the RIVCOM model predicts VMT per service population to decrease in
the future due to improved development and transportation patterns. RIVCOM is the best available tool
to estimate VMT for the City of Palm Springs and the City has identified it as the most appropriate tool to
estimate VMT as part of their VMT guidelines. The findings indicate that the Project is beneficial from a
VMT efficiency perspective. Therefore, the General Plan is expected to produce VMT at a rate that would
not result in a significant impact.
Given the analysis results presented above, the VMT impact is considered less than significant.

5. Level of Service Analysis
Roadway segment and intersection LOS analysis have been provided in this chapter for informational
purposes only and to document consistency with General Plan policies. Some roadway or intersection
facilities may perform at unacceptable levels of service but are not considered significant impacts. CEQA
transportation impact conclusions are based only on VMT.
5.1 Cumulative (2045) Year
This section provides the forecasting methodology and the Cumulative (2045) Year roadway segment
operation analysis for locations in the study area under the No Project (previous General Plan) and Plus
Project (General Plan update) scenarios.
5.1.1 Cumulative (2045) Year Forecasts
RIVCOM is a regional model that is based on the traditional four-step sequential modeling methodology
with “feedback loop” procedures to insure internal modeling consistency. The model incorporates multi-
modal analytical capabilities to analyze the following modes of travel: local and express bus transit, urban
rail, commuter rail, toll roads, carpools, truck traffic, as well as non-motorized transportation which includes
pedestrian and bicycle trips. Regional transportation models, such as RIVCOM, use socioeconomic data to
estimate trip generation, mode choice, as well as several sub-models to address complex travel behavior
and multi-modal transportation issues. The model responds to changes in land use types, household
characteristics, transportation infrastructure, and travel costs such as transit fares, parking costs, tolls, and
auto operating costs.
RIVCOM was used to develop the future traffic volume forecasts. Three model scenarios were utilized in the
forecasting process: Base Year, Future Year No Project, Future Year Plus Project, as described below:
Base Year Model – This scenario contains the base year (2018) land use and roadway network
assumptions.
Future Year Model No Project – This scenario contains the future year (2045) land use and roadway
network assumptions. Additionally, TAZ’s in the City of Palm Springs were overwritten to represent
the No Project land use scenario (e.g., account for regional growth in the region, but growth
assumed in the City is consistent with the old General Plan).
Future Year Model Plus Project – This scenario is identical to the Future Year No Project scenario,
except the new General Plan proposed land use growth by TAZ was incorporated in the City of Palm
Springs.
To develop Cumulative (2045) Year No Project scenario forecasts, the Future Year Model No Project was
compared to the Base Year Model outputs using the difference method. Similarly, to develop Cumulative
25
(2045) Year Plus Project scenario forecasts, the Future Year Model Plus Project was compared to the Base
Year model outputs using the difference method. The difference method was done using standard
techniques consistent with National Cooperative Highway Research Program (NCHRP) Report 255. The
arithmetic difference was taken between the future year and base year model outputs and that difference
was used to determine an annual growth.
That annual growth was then successively added to the existing intersection and roadway volumes (Chapter
3 describes how 2019 roadway volumes were derived using historic counts and StreetLight data) to reach
the cumulative year of 2045. To provide a conservative analysis, negative growth was not allowed in the
Cumulative (2045) Year No Project scenario volumes. If the model predicted negative growth over existing
conditions, the existing conditions volumes were utilized.
5.1.2 Roadway Segment Level of Service
Cumulative (2045) Year No Project and Plus Project roadway segment volumes are shown in Table 11, along
with the number of lanes and roadway segment level of service.
Analysis methodology for the roadway segment level of service calculations is described in Chapter 3.
The proposed plan results in higher traffic volumes Citywide. The following study segments are forecast to
be near or over capacity (LOS E or F):
Highway 111
o North of Vista Chino (LOS F) in both scenarios
Sunrise Way
o Vista Chino to Ramon Road (LOS E and F) in both scenarios
o Ramon Road to E Palm Canyon Drive (LOS E) in the Plus Project scenario
Gene Autry Trail
o North of Vista Chino (LOS E and F) in both scenarios
o Vista Chino to Ramon Road (LOS E) in the Plus Project scenario
o Ramon Road to E Palm Canyon Drive (LOS F) in both scenarios

5.1.3 Intersection Level of Service
The intersection analysis for the two cumulative scenarios is reported in Table 11.
Intersection turning movement forecasts for the Cumulative No Project and Cumulative Plus Project
scenarios are presented in Figure 3 and Figure 4.
Due to the increase in development proposed in the General Plan update, intersection forecasts are
higher in the Cumulative Plus Project scenario than the Cumulative No Project. Directionality of trips for
certain turning movements varies between scenarios based on where land uses are forecast.
Analysis methodology for the intersection level of service calculations is described in Chapter 3.
The following locations are forecasted to operate below the City’s LOS standard LOS D:
Vista Chino at Highway 111
o LOS E and LOS F in the AM peak hour in the Cumulative No Project and Plus Project
scenarios

City of Palm Springs General Plan Update
May 2023
32
6. CEQA Checklist Review
The following significance criteria, included in Appendix G of the California Environmental Quality Act
(CEQA) Guidelines (14 CCR 15000 et seq.), will determine the significance of a traffic impact. Impacts to
traffic resources would be significant if the proposed project would:
6.1.1 Checklist Item A
a) Conflict with a program, plan, ordinance or policy addressing the circulation system, including transit,
roadway, bicycle and pedestrian facilities?
6.1.1.1 Pedestrian and Bicycle Facilities
The Palm Springs General Plan Update Circulation Element provides a comprehensive system of bicycle
lanes, trails, and pathways to enhance bicycle and pedestrian connectivity within the City. Additionally,
the Circulation Element identifies a series of Goals, Policies, and Actions to ensure the integrity and service
levels of these facilities are maintained. Circulation Element Policy CR1.11, Policy CR1.16, Policy CR1.17,
Goal CR6 and Goal CR7 would create, improve or encourage the implementation of pedestrian and
bicycle infrastructure. Given this comprehensive planning effort, the project impact to bicycle and
pedestrian facilities is considered less-than-significant.
6.1.1.2 Transit Facilities
The Palm Springs General Plan Update Circulation Element provides a series of policies to enhance transit
systems. Circulation Element Goal CR4 and Goal CR5 include several policies related to transit
enhancement. Given this comprehensive planning effort, the project impact to transit travel is considered
less-than-significant.
6.1.2 Checklist Item B
b) Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)?
Based on the analysis presented in Chapter 4, implementation of the proposed project would decrease
project generated VMT per Service Population and cumulative Citywide VMT per Service Population.
However, given the uncertainty and speculative influences on both VMT performance and potential
mitigation actions described in Chapter 4, the impact is considered significant and unavoidable.
6.1.3 Checklist Item C
d) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or
incompatible uses (e.g., farm equipment)?
33
The General Plan was developed to minimize conflicts between incompatible uses. Additionally, Action
CR2.3 requires that high-accident locations be studied and improved. As such, this impact is considered
less-than-significant.
6.1.4 Checklist Item D
e) Result in inadequate emergency access?
In general, the Mobility Element improves connectivity and mobility throughout the City. This improved
connectivity and mobility will also improve emergency access throughout the City. Since emergency
accessibility will improve with implementation of the plan, this impact is considered less-than-significant.

6. SAFETY ELEMENT
BACKGROUND AND CONTEXT Protecting and preserving the health, safety, and welfare of the community is an issue of fundamental concern to the City. As such, it is important that the City of Palm Springs maintain and improve programs that effectively address safety and climate change considerations. The Safety Element discusses natural and human-caused hazards that might occur, evaluates how these hazards are projected to change in the future, and presents a comprehensive set of goals and policies to minimize the effects of these hazards. Actions to implement these goals and policy can be found in Appendix X. More detailed information regarding climate change hazards can be found in Appendix X of the Safety Element. The Safety Element serves the following functions:
Develops a framework by which safety considerations are introduced into the land use planning process.
Facilitates the identification and mitigation of hazards for new development, thus strengthening existing codes, project review, and permitting processes.
Presents policies and implementation programs, contained in Appendix X, directed at identifying and reducing hazards in existing development.
Strengthens hazard preparedness planning and post-disaster reconstruction policies.
Identifies how hazards are likely to increase in frequency and intensity due to climate change and provides policies to increase community resilience.
Page 6-2 Palm Springs 2040 General Plan
The Safety Element is divided into nine sections addressing required or supplementary issues identified in California Government Code Section 65302(g). Each section provides an overview of the issue as well as goals and policies to respond to the associated public safety issue. These sections are the following: 1. Disaster Preparedness, Response, and Recovery 2. Seismic Hazards 3. Geologic Hazards 4. Flooding and Dam Inundation 5. Fire Hazards 6. Hazardous Materials and Waste 7. Airport Safety 8. Public Safety 9. Additional Climate Change Hazards
REGULATORY FRAMEWORK Under state law, all counties and incorporated communities in California must prepare a General Plan that addresses several topics, one of which is safety. The Safety Element addresses this topic in accordance with state requirements, which are primarily laid out in California Government Code Section 65302(g). State law requires that the Safety Element address the following:
Protect the community from risks associated with a variety of hazards, including seismic activity, landslides, flooding, and wildfire, as required by the California Government Code Section 65302(g)(1).
Map and assess the risk associated with flood hazards, develop policies to minimize the flood risk to new development and essential public facilities, and establish effective working relationships among agencies with flood protection responsibilities, as required by California Government Code Section 65302(g)(2).
Map and assess the risk associated with wildfire hazards, develop policies to reduce the wildfire risk to new land uses and essential facilities, ensure there is adequate road and water infrastructure to respond to fire emergencies, and establish cooperative relationships between fire protection agencies, as required by California Government Code Section 65302(g)(3).
Palm Springs 2040 General Plan Page 6-3
SAFETY ELEMENT
Assess the risks associated with climate change on local assets, populations, and resources. Note existing and planned development in at-risk areas and identify agencies responsible for providing public health and safety and environmental protection. Develop goals, policies, objectives, and feasible implementation measures to reduce the risks associated with climate change hazards, including locating new public facilities outside of at-risk areas, providing adequate infrastructure in at-risk areas, and supporting natural infrastructure for climate adaptation, as required by California Government Code Section 65302(g)(4).
Identify residential developments in any hazard area that do not have at least two emergency evacuation routes, as required by California Government Code Section 65302(g)(5).
Identify new information relating to flood and fire hazards and climate adaptation and resiliency strategies applicable to the city or county that was not available during the previous revision of the safety element, during each revision of the housing element or local hazard mitigation plan, but not less than once every 8 years, as required by California Government Code Section 65302(g)(6).
RELATIONSHIP TO OTHER PLANS AND PROGRAMS Federal, state, and local regulations and policies such as the California Environmental Quality Act (CEQA), the California Government Code, the Uniform Building Code, and the Palm Springs Municipal Code regulate and/or influence land use and development in Palm Springs. Not only do they help to protect the health, safety, and welfare of Palm Springs residents, visitors, and businesses by ensuring that proper analyses are conducted, sound construction practices are implemented, and uses are appropriately sited within the city, but they can also help to minimize the recovery time following a disaster.
Other General Plan Elements The Safety Element is one of several elements of the Palm Springs General Plan. Other social, economic, political, and aesthetic factors must be considered and balanced with safety needs. Rather than compete with the policies of related elements, the Safety Element provides policy direction and designs safety improvements that complement the intent and policies of other General Plan elements. How land uses are determined in areas prone to natural hazards,
Page 6-4 Palm Springs 2040 General Plan
what regulations limit development in these areas, and how hazards are reduced for existing development, are all among issues that tie the elements together. For instance, Land Use Element diagrams and policies must consider the potential for various hazards identified in the Safety Element and must be consistent with the policies to address those hazards. The Recreation, Open Space, and Conservation Element is also closely tied to the Safety Element. Floodplains, for example, are not only hazard areas, but often serve as sensitive habitat for threatened or endangered species or provide recreation or passive open space opportunities for residents and visitors. As such, flood and inundation policies balance the need to protect public health and safety with the need to protect habitat and open space. Safety Element policies, especially those concerning evacuation routes and critical facilities, must also be consistent with those of the Circulation Element. Interstate 10 is the primary evacuation route in the region, which is supported by major arterial routes such as State Route 111, Palm Canyon Drive, Ramon Road, and Sunrise Way shown in the City’s Transportation and Circulation Element. Policies and information in this Safety Element should not conflict with those in other elements.
Palm Springs Local Hazard Mitigation Plan Palm Spring’s Local Hazard Mitigation Plan (LHMP) is a plan to identify and profile hazard conditions, analyze risk to people and facilities, and develop mitigation actions to reduce or eliminate hazard risks in in the city. The City prepared the LHMP in accordance with the federal Disaster Mitigation Act of 2000 and the Federal Emergency Management Agency’s (FEMA’s) LHMP guidance, and FEMA has certified the City's most recent LHMP. The mitigation actions in the LHMP include both short-term and long-term strategies, and involve planning, policy changes, programs, projects, and other activities. The LHMP and Safety Element address similar issues, but the Safety Element provides a higher-level framework and set of policies, while the LHMP focuses on more specific mitigation actions, often short-term. The City’s LHMP focuses on mitigation-related actions, while the Safety Element also includes policies related to emergency response and recovery activities. The current LHMP is incorporated into this Safety Element by reference, as permitted by California Government Code Section 65302.6. The current version of the LHMP can be accessed here: https://www.palmspringsca.gov/government/departments/emergency-management/local-hazard-mitigation-plan-lhmp

SAFETY ELEMENT
Palm Springs Emergency Operations Plan The Emergency Operations Plan (EOP) provides procedures for City staff that address readiness, mobilization, and contingency planning to allow for uninterrupted delivery of essential City functions during disasters. The EOP aims to saves lives, prevent property damage, protect and assist the public with emergencies, and facilitate recovery after a disaster. The City is prepared to maintain its core level of service during emergency situations, such as fire, earthquake, or other hazardous events through implementation of the EOP.
CLIMATE CH ANGE VULNERABILITY Climate change is expected to affect future occurrences of natural hazards in and around Palm Springs. Many of these hazards will likely become more frequent and intense in coming years and decades. In some cases, these trends have already begun, such as droughts, extreme heat, and wildfires. According to California’s
Fourth Climate Change Assessment,1 Palm Springs can expect to experience various changes to climate change hazards.
Both droughts and floods are expected to become more frequent because precipitation is expected to occur in fewer, more intense storms. Although Palm Springs is likely to experience only a slight increase in overall annual precipitation levels, the region is expected to see an increase in the number of extreme precipitation events. As a result, floods are expected more often in Palm Springs, and climate change may expand the parts of the city that are considered flood prone. Climate change is also expected to increase the frequency and severity of droughts, straining aquatic habitats and water supplies in the city.
Warmer temperatures are projected to cause an increase in extreme heat events, which are days when the high temperature significantly exceeds normal levels. The number of extreme heat days is expected to rise in Palm Springs, in addition to an increase in the average daily high temperatures. Extreme heat poses a significant human health risk, especially

to children, outdoor workers, seniors, persons experiencing homelessness, and undocumented persons. Some infrastructure and community services may be damaged by very high temperatures, constraining their ability to meet community needs.
Climate change can increase the rates of infection for various diseases because many of the animals that carry diseases are more active during warmer weather. There are several diseases that are linked to climate change and can be harmful to the health of Palm Springs community members, such as hantavirus pulmonary syndrome, Lyme disease, and West Nile virus. Many of these diseases are carried by animals, such as mice and rats, ticks, and mosquitos, which are usually seen as pests even if they do not cause infections. Warmer temperatures earlier in the spring and later in the winter can cause these animals to be active for longer periods, increasing the time that these diseases can be transmitted.
Severe weather events, such as high winds, sandstorms, and heavy rainfall, may become more frequent and intense. Climate change is expected to cause an increase in intense rainfall, which can cause flash flooding. In Palm Springs, most severe weather is linked to high winds. These winds can also pick up dust and other particulate matter from the desert or dry lakebed of the Salton Sea, causing sandstorms that lower visibility and cause toxic particulate matter to get into buildings and cause respiratory illnesses. The types of dangers posed by severe weather vary widely and include injuries or deaths, damage to buildings and structures, and roads blocked by debris or sand.
Wildfires can be sparked by lightning, malfunctioning equipment, vehicle crashes, and many other causes. Warmer temperatures, an increase in drought conditions, and extreme wind events are likely to create more fuel for fires in natural and rural areas, leading to a greater chance that a spark will grow into a dangerous blaze. Climate change is also expected to extend the fire season throughout much (or even all) of the year. Because wildfires burn the trees and other vegetation that help stabilize a hillside and absorb water, more area burned by fire may also lead to an increase in landslides and debris flows.
Palm Springs 2040 General Plan Page 6-7
SAFETY ELEMENT
Under California Government Code Section 65302(g)(4), the Safety Element is required to include a vulnerability assessment that looks at how people, buildings, infrastructure, and other key community assets may be affected by climate change. The City conducted a Climate Vulnerability Assessment in Spring 2022 to analyze Palm Springs’ susceptibility to climate change hazards. The City of Palm Springs’ vulnerability assessment, prepared in accordance with the most recent available guidance in the California Adaptation Planning
Guide, assesses how eight different climate-related hazards (air quality, drought, extreme heat and warm nights, flooding, human health hazards, landslides, severe weather, and wildfire) may affect 66 different population groups and community assets. Each population or asset received a score of V1 (minimal vulnerability) to V5 (severe vulnerability) for each climate change hazard. The Vulnerability Assessment indicates that Palm Springs populations and assets are most vulnerable to flooding and wildfire. The Vulnerability Assessment Report provides an overview of the methods; summary of the climate change hazards, populations, and assets included in the assessment; and the full list of results, which can be found in Appendix X. The results of the Vulnerability Assessment are integrated into the hazard and other safety sections below.
Page 6-8 Palm Springs 2040 General Plan
GOALS, POLICIES, AND ACTIONS This section contains background information and policy direction related to hazards and safety provisions within the city. The hazard and safety items addressed in this element should be given careful consideration when new development, roads, parks, critical emergency facilities, infrastructure, or other projects are designed.
DISASTER PREPAREDNESS, RESPONSE, AND
RECOVERY The Palm Springs area is subject to significant natural and human-caused hazards that pose risks to life and property. Advance preparation for potential disasters can prevent losses of life and property, improving the City’s ability to respond to and recover from emergency situations created by hazardous events. Due to the large number of public, quasi-public, and private agencies involved in disaster preparedness planning, cooperation and coordination between agencies are essential. Depending on the type of incident, several different agencies and disciplines may be called in to assist with emergency response, including emergency medical, health, fire and rescue, police, and public works. The challenge is to accomplish the work at hand in the most effective manner, maintaining open lines of communication between the different responding agencies to share and disseminate information, and to coordinate efforts. This is primarily accomplished through implementation of the Emergency Operations Plan during a disaster. Once a disaster has occurred, the capability of the City to respond to the situation at hand affects how quickly it can recover from impacts. The City of Palm Springs participates in the Standardized Emergency Management System (SEMS), which is required by the California Government Code and was developed to provide a “common language” for emergency response personnel to request resources and equipment from other agencies. In addition to resource allocation, SEMS was established to minimize the duplication of efforts during emergency response by defining common tactics and identifying a clear chain of command. The Standardized Emergency Management System adopted the California
Palm Springs 2040 General Plan Page 6-9
SAFETY ELEMENT
Master Mutual-Aid Agreement, designed to ensure that adequate resources, facilities, and other support are provided to jurisdictions whenever their own resources are insufficient to cope with a given emergency. The City of Palm Springs participates in the California Master Mutual-Aid Agreement. The State Office of Emergency Services, Southern Region (Mutual Aid Region VI), serves the mutual-aid region that encompasses San Diego County, Imperial County, Riverside County, San Bernardino County, Inyo County, and Mono County. Automatic aid pacts with the Riverside County Emergency Management Department and local fire departments in nearby cities provide additional emergency management and response services in Palm Springs. Palm Springs Fire Department provides a variety of public safety services, including fire protection, medical aid, rescue, hazardous materials response, and educational safety programs such as Community Emergency Response Team training. Other services include emergency alerts, the Community Risk Reduction program, fire plan review and inspection, and wildfire preparedness. The City of Palm Springs utilizes an Everbridge emergency alert mass notification system to notify the community of a disaster and distribute emergency information and instructions before, during, and after a disaster. This system alerts residents throughout the city about disasters, major emergencies, and other urgent information via text messages, email, phone, landline, and other means of communication. The Palm Springs Emergency Management Department participates in the Federal Emergency Management Agency’s (FEMA) Community Emergency Response Training (CERT) program, a series of classes that train residents to effectively respond in dangerous situations if emergency services are delayed in responding. In the CERT program, citizens learn to manage utilities and put out small fires, perform CPR, control bleeding, provide basic medical aid and treatment for shock, search for and rescue victims safely, organize themselves and spontaneous volunteers to be effective, and collect disaster intelligence to support first-responder efforts. Additional educational resources are provided to the public via disaster-preparedness presentations, flyers, and a telephone information-retrieval system.
Essential, Sensitive, High-Occupancy Facilities Essential facilities are infrastructure and buildings whose continued functioning is necessary to maintain public health and safety following a disaster. These include water, sewage, electrical power,

communication, transportation (highways, bridges, railroads, and airports), natural gas, and liquid fuel systems as well as police stations, fire stations, and emergency operation centers. These facilities are critical to the health and welfare of Palm Springs and are especially vital following hazard events. Essential facilities are particularly important for emergency response and recovery after a disaster that causes considerable citywide damage. Sensitive facilities manufacture, store, or sell hazardous materials or are socially significant facilities such as schools, nursing homes, housing for the elderly, and those serving people with access and functional needs. These facilities should be designed to remain functional during and immediately after a disaster; however, they may provide limited services if the essential facilities they depend on are disrupted. High-occupancy facilities house or support the assembly of large groups of people, such as conference centers, libraries, multifamily housing, or similar facilities. These facilities could serve as gathering spaces during a disaster and should be protected from hazardous events. Because essential facilities deliver critical services to the community, it is important to consider the impacts to society from their disruption or failure in a disaster. The loss of essential infrastructure can have far-reaching, long-term effects on businesses, jobs, environmental quality, health, and people displaced from their homes. The severity of these effects often increases if services take a longer time to restore.
Evacuation With advanced warning, evacuation can be effective in reducing injury and loss of life during a catastrophic event. Figure 6-1,
Evacuation-Constrained Residential Parcels, shows the evacuation routes and evacuation-constrained residential parcels throughout the city. Primary emergency access and evacuation routes include I-10, Indian Canyon Drive, Highway 111, Palm Canyon Drive, Sunrise Way, Farrell Drive, Gene Autry Trail, Date Palm Drive, San Rafael Drive, Vista Chino, Tahquitz Canyon Way, Ramon Road, and Dinah Shore Drive. All evacuation routes in Palm Springs face a potential disruption from a flood, earthquake, or severe weather event, which may block roadways, damage the roadway surface, or collapse overpasses. In the event of widespread disruption to local evacuation

routes, remaining evacuation routes may become congested, slowing down evacuation of the community or specific neighborhoods. This issue may be compounded since evacuation routes for Palm Springs will also likely serve as evacuation routes for surrounding communities in the Coachella Valley, and so potential disruptions may have regional effects. An analysis of the city’s roadway network and parcels conducted as part of the Safety Element Update, as shown on Figure 6-1, shows that there are several evacuation-constrained residential parcels throughout the city. The evacuation-constrained parcels in western Palm Springs could be subject to wildfire and landslide hazards, and evacuation-constrained parcels in northern and southern areas of the city could be subject to flood hazards. All evacuation-constrained parcels are in at least one hazard-prone area and may have only one emergency evacuation route. The lack of multiple emergency access points limits roadway access for these properties, which may create difficulties if there is a need to evacuate.
GOAL SA1:
Minimized risk to life, property, and essential facilities from
disasters through emergency preparedness, response, and
recovery.
Policies SA1.1 Locate new essential facilities outside of hazard prone areas, including Very High Fire Hazard Severity Zones, 100-year and 500-year floodplains, moderate to high landslide susceptibility areas, and Alquist-Priolo Fault Zones to ensure that they remain in operation during and after hazard events. SA1.2 Collaborate with agencies and organizations that own and operate essential structures to ensure, to the fullest extent possible, that in the event of a major disaster, essential structures and facilities remain safe and functional, including but not limited to, retrofitting existing essential facilities to withstand hazardous events.

SEISMIC HAZARDS The City of Palm Springs is in an area subject to substantial seismic hazards, such as earthquakes, liquefaction, and earthquake-induced slope failure and landslides. These seismic hazards can affect the structural integrity of buildings and utilities and, in turn, cause property damage and potential loss of life. Although it is not possible to prevent earthquakes, their destructive effects can be minimized through comprehensive hazard-mitigation programs and efforts.
Earthquakes and Fault Zones The City of Palm Springs is in an area with numerous active faults. At least two active faults, the San Andreas and Garnet Hill Faults, depicted on Figure 6-2, Regional Faults, extend through the northern portions of the city. Both fault zones, along with other faults in the greater region, such as the San Gorgonio Pass and San Jacinto Faults, also have the potential to produce strong seismic shaking in Palm Springs.
Seismic Shaking: Lateral
movement, or acceleration, of the
ground during an earthquake.
Surface Rupture: Occurs when
movement on a fault deep within
the earth breaks through to the
surface. Although surface rupture
typically results in a small
percentage of the total damage in
an earthquake, being too close to a
rupturing fault can cause severe
damage to structures.
Surface Trace: Commonly
referred to as a “fault line,” it is the
intersection of a fault plane with
the surface of the earth.

SAFETY ELEMENT
The potential for ground rupture due to fault movement is commonly related to the seismic activity of known fault zones. Active faults are present along the northernmost reaches of the city, where the traces of the Garnet Hill and San Andreas Faults have been mapped. These faults have the potential to generate surface rupture or ground deformation in Palm Springs. As shown on Figure 6-2, Alquist-Priolo Fault Zones occur along the Garnet Hill Fault north of the city, the San Andreas Fault north and east of the city, and the Hot Springs and Thomas Mountain Faults southwest of the city. Under the Alquist-Priolo Earthquake Fault Zoning Act, the location of structures for human occupancy across the surface trace of an active fault is restricted. A Riverside County Fault Management Hazard Zone has been assigned to the portion of the Garnet Hill fault that extends to the north of the city. Riverside County has established Fault Management Hazard Zones in order to require subsurface investigations of the Garnet Hill Fault to determine, over time, if the traces of the fault are active. This designation for the Garnet Hill Fault allows Palm Springs to regulate future development across the trace of the fault. Historically, major earthquakes affecting Palm Springs included the 1857 Fort Tejon earthquake with a magnitude (MW) of 7.9; the 1992 Landers-Big Bear earthquakes of MW 7.3; the 1986 North Palm Springs earthquake of a MW of 6.0; the 1999 Hector Mine earthquake of MW 7.1; and the 2019 Ridgecrest earthquake of MW 7.1.
Laws to Mitigate Earthquake Hazards The State of California regulates development in potentially seismically active areas through a variety of tools that reduce or mitigate potential hazards from earthquakes or other geological hazards. The California Building Standards Code (BSC) contains provisions to safeguard against major structural failures or loss of life caused by earthquakes or other geologic hazards and identifies zones of seismic activity subject to varying degrees of potential impact and frequency of large earthquakes. The City of Palm Springs is potentially subject to the highest changes in speed or velocity due to seismic shaking. Enacted in 1986, the Unreinforced Masonry Law required cities and counties to identify potentially hazardous unreinforced masonry (URM) buildings in their jurisdictions, establish a URM loss-reduction program, and notify the owners of such buildings of the potential earthquake hazard their buildings pose. Although this law sunset in
Page 6-20 Palm Springs 2040 General Plan
2009, the California Building Code contains specific requirements to ensure the seismic safety of URM buildings. The primary purpose of the Alquist-Priolo Earthquake Fault Zoning
Act is to prohibit the location of structures for human occupancy across active surface traces of fault lines until geotechnical investigations determine that a potential building site is safe for habitation. The Act also requires cities to disclose to the general public, through the use of maps and other appropriate materials, areas that are subject to seismic hazards. The Seismic Hazards Mapping Act (SHMA) of 1990 addresses nonsurface fault rupture earthquake hazards, including strong ground shaking, liquefaction, and seismically induced landslides. The California Geological Survey (CGS) has not yet mapped the Palm Springs area under the SHMA. However, performing geological studies in those areas identified as having a liquefaction or slope-instability hazard would reduce the potential for damage from these hazards.
Liquefaction Liquefaction occurs when loose, soft, unconsolidated, or sandy soils that are saturated with water are subjected to ground vibrations during a seismic event. Significant ground shaking causes soil to lose strength and “liquefy,” triggering structural distress or failure due to the settling of the ground or a loss of strength in the soils underneath structures. As shown on Figure 6-3, Liquefaction Potential, the northern and eastern areas of the city have the possibility of being affected by liquefaction. However, t his hazard is considered low in the Palm Springs area because the approximate depth to groundwater is greater than 50 feet. Research and historical data indicate that loose, granular materials saturated with groundwater and at depths of less than 50 feet, with silt and clay contents of less than 30 percent are most susceptible to liquefaction. Shallow groundwater is in the downtown area immediately surrounding the Agua Caliente Springs, which can increase the potential for liquefaction. A strong earthquake could cause liquefaction in this area, most likely expressed as “sand volcanoes” immediately surrounding the spring. Seasonal fluctuations in groundwater levels and the introduction of residential irrigation increase liquefaction risk.

Earthquake-Induced Slope Failures and Landslides Strong ground motions can worsen existing unstable slope conditions, particularly if coupled with saturated ground conditions. Earthquake-induced slope failures generally include rock falls, landslides, and debris flows that can overrun structures, people, or property; sever utility lines; or block roads, which can hinder rescue operations after an earthquake. After the 1986 North Palm Springs earthquake, numerous landslides consisting primarily of debris slides and rockfalls were reported over an area of 232 square miles. The southern part of Palm Springs is most vulnerable to seismically induced slope failure due to the steep terrain of the San Jacinto Mountains. The areas at the foot of the San Jacinto Mountains or below hills covered with large boulders are most susceptible to rockfall. In areas where there is development at the base of steep slopes, dislodged boulders can roll down to roadways, damaging roadways and destroying homes. Earthquakes are likely to continue on an occasional basis and are likely to be moderate to severe based on the close proximity of the Garnet Fault, San Andreas Fault, and San Jacinto Fault. According to the Local Hazard Mitigation Plan, some earthquakes may cause moderate or complete damage to nearly 25 percent of the structures in the city. According to the United States Geologic Survey, there is a 25 percent chance of a 6.7 MW or greater earthquake occurring from the San Andreas Fault and a 7 percent chance of a similar-size earthquake along the San Jacinto Fault by 2044. While liquefaction potential is low in most areas of the city, large earthquakes from faults such as the San Andreas Fault and San Jacinto Fault may cause significant damage to homes and businesses, and subsequently cause rockfalls or landslides.
Climate Change and Seismic Hazards There is no substantial evidence of a link between climate change and seismic activity, so climate change is not expected to meaningfully change the frequency or intensity of hazards associated with seismic activity.

GEOLOGIC HAZARDS Geologic hazards generally consist of land movement processes not linked to seismic activity that have the potential to cause harm to people and property. In Palm Springs, these hazards include landslides and debris flows, ground subsidence, erosion, and windblown sand.
Landslides and Debris Flows Landslides occur when a mountainside becomes unstable, causing soil and rocks to slide downslope. Landslides can include rock falls, deep failures of slopes, and shallow debris flows. Landslides are most common on steep slopes and mountainsides made up of loose soil or other material where excavation and grading, drainage alterations, or changes in vegetation have occurred. Intense rainfall and other environmental factors can also cause boulders to fall or roll down from these steep slopes, posing a threat to structures and people. Mountainsides commonly absorb water, which increases instability of the slope and may increase the risk of slope failure. Steep slopes made of loose or fractured material are more likely to slide. Planning for developments and infrastructure in these areas should be supported by site-specific geotechnical analyses for slope stability.
Page 6-26 Palm Springs 2040 General Plan
Figure 6-4, Landslide Susceptibility, shows the areas most susceptible to landslides in the city. Steeper slopes in the San Jacinto Mountain range are in high landslide susceptibility areas, and the flatter, urban area of Palm Springs is outside of this zone. Areas of high topographic relief, such as steep canyon walls, are most likely to be impacted by rockfalls, rockslides, soil slips, and to a lesser degree, large landslides. Likewise, locations in the Garnet Hill and Whitewater Hill areas have unstable soil types along which slope failures could occur. During exceptional storm periods or prolonged rainfall, the risk of debris flows increases. Debris flows are the most dangerous and destructive type of slope failure, generally consisting of a rapidly moving slurry of water, mud, rock, vegetation, and debris. This type of slope failure usually occurs during an intense rainfall event following saturation of the soil by previous rains. Rockfalls are free falling or tumbling masses of bedrock that have broken off steep canyon walls or cliffs. Rockfalls can happen wherever fractured rock slopes have become steep from stream erosion or human activities. This hazard is present in the hills that frame the southern part of the Coachella Valley along the southwestern portions of Palm Springs. Rockfalls can occur suddenly and without warning but are more likely to occur in response to earthquake-induced ground shaking, during periods of intense rainfall, or as a result of human activities such as grading and blasting.
Ground Subsidence Ground subsidence is the gradual settling or sinking of the ground surface with little or no horizontal movement. In the areas of southern California where ground subsidence has been reported, this phenomenon is usually associated with the extraction of oil, gas, or groundwater or the organic decomposition of peat deposits. Ground subsidence can also occur as a response to natural forces such as earthquake movements.

SAFETY ELEMENT
Ground subsidence can cause earth fissures, sinkholes, depressions, and disruption of surface drainage. Permanent (irreversible) subsidence can occur if groundwater is removed from clay and silt layers in an underlying aquifer. The Indio Subbasin of the Coachella Valley Groundwater Basin is managed by water service agencies in the region, and the portion under Palm Springs is managed by the Desert Water Agency to minimize ground subsidence. Since 2010, the Indio Subbasin has had rises in groundwater—from 7 to 40 feet—due to groundwater management practices and reductions in overall water use. This trend has minimized subsidence throughout the city.
Erosion and Sedimentation
Erosion, the removal of earth materials by moving water, wind, or ice, is a significant geologic hazard in the Palm Springs area due to topography and weather conditions. Erosion and sedimentation are influenced by several factors, including climate, topography, soil and rock types, and vegetation. Natural erosion processes are often accelerated through human activities—agricultural or related to land development. Grading increases the potential for erosion and sedimentation by removing protective vegetation, altering natural drainage patterns, compacting the soil, and constructing cut-and-fill slopes, which may be more susceptible to erosion than the natural condition. Because of the high topographic relief in and around Palm Springs, erosion and sedimentation are significant elements of the natural setting. Erosion may eat away at the mountains of western Palm Springs, and sedimentation may deposit the eroded material into eastern Palm Springs via water or wind. Erosion and sedimentation are also important factors to consider when developments are adjacent to slopes and drainage channels, not only during the design of a project, but also during construction and long-term maintenance of the developed site. Development can minimize the impacts of sedimentation by increasing permeable surfaces on a project site to decrease flooding and sedimentation downstream of the project.
Windblown Sand Strong winds are endemic to the Palm Springs area due to the tunneling effect of air through the narrow San Gorgonio Pass. Wind can damage land and vegetation, and in this region, where surface sediments are predominantly dry and granular, windblown sand and

sand and other earth materials

Drive.
dust can impact surface improvements, air quality (creating health hazards), and visibility. These winds can also pick up dust and particulate matter from the desert or dry lakebed of the Salton Sea, causing sandstorms with toxic particulate matter. Wind erosion commonly occurs in flat, bare areas; dry, sandy soils; or anywhere the soil is loose, dry, and finely granulated. Wind erosion damages land and natural vegetation by removing soil from one place and depositing it in another. Since high winds blow down the center of the Coachella Valley, recreational and resort communities that first developed in the upper Coachella Valley were generally in areas sheltered from these winds, tucked in coves at the base of the mountains. However, as the area has grown, development has had to move into the central axis of the valley and into the high-wind areas. Most of the urban development in Palm Springs lies in an area of high susceptibility to wind erosion. Recreational land uses, especially use of off-road vehicles, can also accelerate erosion in the area. Wind and windblown sand pose an environmental hazard throughout the Coachella Valley. Buildings, fences, roads, crops, automobiles, trees, and shrubs can all be damaged by abrasive blowing soil. In some places, windblown sand has actually forced the abandonment of dwellings and subdivided tracts in the central Coachella Valley. In Palm Springs, windblown sand has repeatedly caused the closure of roads, costing the City thousands of dollars in cleanup. The roads with the most frequent closures include Indian Canyon Drive, Gene Autry Trail, and Vista Chino.
Climate Change and Geologic Hazards Geologic hazards may increase due to increases in severe weather and heavy precipitation events due to climate change. Scientists project that climate change will increase the frequency and intensity of heavy rainfall in Palm Springs, which will likely increase landslides, debris flows, erosion, and sedimentation. More frequent drought conditions could lead to a heavier reliance on groundwater, increasing the probability of ground subsidence. As described in the Inland Desert Summary Report from the California Fourth Climate
Change Assessment, the connection between climate change and severe winds is not as well established as other hazards, but new

evidence suggests that these forms of severe weather may occur more often than in the past.

SA3.10 Encourage the incorporation of wind barriers, architectural design or features, and drought-resistant ground coverage in new development site designs to mitigate the impacts from erosion and windblown sand.
FLOOD AND DAM INUNDATION HAZARDS
Flooding The City of Palm Springs, like most communities in southern California’s desert climate, is subject to unpredictable seasonal rainfall. Most years the scant winter rains are barely sufficient to turn the hills green for a few weeks, but every few years the region is subjected to periods of intense and sustained precipitation that results in flooding. The Federal Emergency Management Agency (FEMA) cites that flooding is one of the most destructive natural hazards in the world, responsible for more deaths per year than any other hazard. Major flooding occurred in Palm Springs in 1938, when the Whitewater River flooded the Coachella Valley. Overflow from the Tachevah Creek caused major flooding in Downtown Palm Springs and people in the city were isolated for nearly a week. Similarly, in the winter of 1965, the Cottonwood Creek overflowed Interstate 10 east of Highway 111, blocking traffic and isolating the City of Palm Springs. More recently, heavy rainfall created major flooding events in December 2010, September 2014, and February 2019. Therefore, the potential for flooding is a safety concern that Palm Springs continues to address. Portions of Palm Springs are susceptible to storm-induced flooding of the San Gorgonio River, Whitewater River, and other drainages that extend across the city. Palm Springs is susceptible to flash flooding, since the local mountains are very steep and consist of rock types that are fairly impervious to water, meaning that little precipitation is absorbed into the ground. Instead, rainwater and snowmelt flow across the surface as runoff, collecting in the major drainages that

SAFETY ELEMENT
pass through the city. Because of the steep terrain and scarcity of vegetation, water from major storms can collect rapidly and run off quickly, overcoming human-made and natural channels and resulting in flash flooding. Flooding is also expected to occur on the alluvial fans that the developed part of the city occupies, primarily from stormwater. Flood-control structures built and maintained by the Riverside County Flood Control and Water Conservation District (RCFCWCD) have helped reduce flood damage in the city since they were installed. Outside of the developed area of the city, most drainage channels are still in their natural state. Due to the construction of flood-control structures, sheet flow in most of these areas is estimated to be infrequent in occurrence and less than one foot deep. FEMA and the California Department of Water Resources has identified 100- and 500-year flood zones, which are shown on Figure 6-5, Flood Hazards. These include the Whitewater and San Gorgonio River floodplains and areas along Snow Creek, Blaisdell Creek, Chino Creek, Palm Canyon Wash, and Tahquitz Creek. Some developed areas in southern Palm Springs are within the 100-year and 500-year floodplain, as are several areas outside of the highly developed portion of the city. The mountains surrounding the developed portions of Palm Springs have the potential to increase flood problems by filling or plugging structures meant to convey water through the city. Figure 6-5 identifies areas within the city that have the potential to be impacted in the event of a 100- or 500-year flood. FEMA’s Flood Insurance Rate Maps (FIRMs) provide more detailed flood hazard map information. FIRMS are available for reference from FEMA. The National Flood Insurance Program makes federally subsidized flood insurance available in communities that agree to adopt and enforce floodplain management ordinances to reduce future flood damage. Owners of all structures within the FEMA-mapped 100-year flood hazard areas are required to purchase and maintain flood insurance as a condition of receiving a federal mortgage or home equity loan on that structure. National flood insurance is available in the City of Palm Springs; homeowners within the 500-year flood zones, and even outside these zones, should be encouraged to buy flood insurance.

the City Municipal Code contains additional regulations designed to reduce the impacts of flood hazards. The City has also adopted and is implementing a master drainage plan developed and adopted in conjunction with RCFCWCD. Major flood control structures in the Palm Springs area include the Whitewater River Levee, the Chino Canyon Levee and Channel, Tahquitz Creek Levee, and the Palm Canyon Wash Levee. The levee between Palm Canyon Wash and Indian Drive, maintained by the RCFCWCD, protects the portion of the city south of the Whitewater River from flooding. The Chino Canyon Levee and Channel protect the northern part of the highly developed Palm Springs area from 100- and 500-year flooding from Chino Creek and the Whitewater River. The Palm Canyon Wash levee directs flows from Palm Canyon and Arenas Canyon northeastward to the Tahquitz Creek, then eastward to the Whitewater River. It provides 100-year storm protection on the north side of the channel down to Tahquitz Creek and on the south side of Tahquitz Creek channel to the Whitewater River.
Dam Inundation Flooding resulting from dam failure is a potential hazard for the city. The Tachevah Creek Detention Reservoir and the Tahquitz Creek Debris Basin are two flood-control structures in the Palm Springs area required by the California State Water Code to be monitored for structural safety and that have the potential to pose a flooding risk to the city. General limits of flood hazard due to dam failure are shown on Figure 6-6, Dam Inundation Areas. The Tachevah Creek Detention Reservoir, about 1,200 feet downstream from the mouth of Tachevah Canyon, is formed by a 42-foot-high embankment constructed of compacted earth fill and has a capacity of approximately 650 million gallons. This dam was built in 1964 and protects the highly urbanized central part of the city from floods and debris flows. Figure 6-6 shows the inundation path that would most likely occur in the event of dam failure at this facility.

The Tahquitz Creek Debris Basin, which is a considerably smaller structure, was designed and constructed to reduce the risk of flooding that the Tahquitz Creek has historically posed to Palm Springs. Completed in May 1991 by the U.S. Army Corps of Engineers, the basin consists of a natural channel and dam with a debris storage capacity of about 33 million gallons and a two-mile reach of grass-lined channel used as a golf course and bicycle and equestrian trails.
Inundation from Aboveground
Storage Tanks Inundation from aboveground storage tanks is another safety consideration for the City of Palm Springs. Flooding can occur if strong ground shaking causes structural damage to aboveground water tanks. Sloshing water can lift a water tank off its foundation or break the pipes leading to the tank, releasing water to surrounding areas. All water tanks in the City of Palm Springs are owned and operated by the Desert Water Agency and meet or exceed the design standards and safety requirements applicable at the time the tanks were constructed.
Seiche Potential A seiche is an earthquake-generated wave occurring in an enclosed body of water, such as a lake, reservoir, or harbor. Ground shaking caused by earthquakes can cause oscillations, or sloshing, in enclosed bodies of water, forming a wave that may spill over and flood adjacent land uses. In the Palm Springs area, seiching is not anticipated to pose a significant risk to facilities such as recharge basins and human-made lakes due to their shallow nature and the quick absorption of water into the sandy underlying surfaces. The City of Palm Springs does not have open reservoirs. However, sloshing within a steel water storage tank can cause damage or failure of the structure. Seiching in swimming pools can also occur, and since pools are relatively deep, it is not unusual for pool owners to report a loss of one or more feet of water due to sloshing during an earthquake.
Climate Change and Flood and Dam Inundation
Hazards Although climate change may not change average precipitation levels significantly, scientists expect that it will cause more years with

extreme precipitation events. This means that more years are likely to see intense storm systems that drop precipitation over a short enough period to overwhelm storm drain systems and flood protection infrastructure, leading to more frequent flash flooding. Because of this, floods are expected to occur more often in Palm Springs, and climate change may expand the parts of the city that are considered flood prone. Although there are no specific flooding projections for the city, flood events are expected to become more frequent, and it is possible that the areas subject to flooding will expand. While the risk and associated short- and long-term impacts of climate change are uncertain, experts in this field tend to agree that among the most significant impacts include those resulting from increased heat and precipitation events that cause increased frequency and magnitude of flooding. Increases in damaging flood events will cause greater property damage, public health and safety concerns, displacement, and loss of life. Displacement of residents can include both temporary and long-term displacement, increase in home and renters’ insurance rates, or restriction of insurance coverage in vulnerable areas.

URBAN FIRE AND WILDFIRE HAZARDS
Wildfires Wildfires are a significant hazard in California, where they have always been part of the natural environment. Large areas of southern California are particularly susceptible to wildfire due to the region’s weather, topography, and native vegetation. The typically mild winters characteristic of the region’s Mediterranean climate result in an annual growth of grasses and plants that dry out during the hot summer months. This dry vegetation provides fuel for wildfires in the autumn, when the area is intermittently impacted by Santa Ana winds—the hot, dry winds that blow across the region in the late fall. Although dangerous, wildland fire is a natural process and a necessary part of the natural ecosystem of southern California. Relatively few wildland fires have occurred in the urbanized areas of Palm Springs within the past ten years. However, as shown on Figure 6-7, Historic Wildfire Perimeters, there have been six major fires near Palm Springs in recent decades. Between 1980 and 1994, three very large wildfires occurred in the San Jacinto Mountains and foothills along the western border of Palm Springs and its sphere of influence—the Dry Falls fire of 1980, the Tram Fire of 1985, and the Palm Fire of 1994. The Blaisdell Canyon Fire of 2005 burned more than 5,000 acres in the mountains above Palm Springs proper, threatening the Palm Springs Aerial Tramway area. In 2014, the Mountain Fire burned land directly to the east of the city in the San Jacinto Mountains, and in 2020, the Snow Fire burned areas in northern Palm Springs near the San Gorgonio Pass. Fortunately, these fires were mostly limited to undeveloped areas of mountainous terrain.

As shown on Figure 6-8, Fire Hazard Severity Zones, the western and southwestern portions of the city, specifically the neighborhoods along the foothills and canyon mouths, are in Very High Fire Hazard Severity Zones. The areas with more vegetation—such as in the lower canyon reaches draining the San Jacinto Mountains, including Tachevah Canyon, Tahquitz Creek, Andreas Canyon, and Palm Canyon—where water may be more plentiful, are also highly susceptible to wildfires. The Palm Springs Fire Department is responsible for fire protection, planning, and response within these areas. The San Jacinto Mountains to the west of the city limits are in State Responsibility Areas for fire protection and contain lands within Very High, High, and Moderate Fire Hazard Severity Zones. The California Department of Forestry and Fire Protection (CAL FIRE) provides fire protection services in these areas. Figure 6-8 also shows the Federal Responsibility Areas in hatched lines, indicating lands owned and managed by Agua Caliente Band of Cahuilla Indians, U.S. Forest Service, or Bureau of Land Management. The Agua Caliente Band of Cahuilla Indians is the largest single landowner in Palm Springs, and therefore the Federal Responsibility Area overlaps with the State and Local Responsibility Area Fire Hazard Severity Zones. The wildland-urban interface (WUI) is an area where buildings and infrastructure (e.g., cell towers, schools, water supply facilities) mix with areas of flammable wildland vegetation. The WUI is composed of interface, intermix, and influence communities. The distinction between these is based on the characteristics and distribution of houses and wildland vegetation across the landscape. Hundreds of homes now border flammable vegetation areas in California. According to a publication in the International Journal of Wildfire, the interface WUI in California contained 50 percent of buildings destroyed by wildfire, whereas intermix WUI contained only 32 percent. Human-caused fires are the leading cause of wildland fires, and with thousands of people living near and visiting wildland areas, the probability of human-caused fires is growing. Figure 6-9,
Wildland-Urban Interface, shows the WUI areas in Palm Springs. Interface areas are located along the mountainside generally south and west of Palm Canyon Drive. The influence zone is just to the west of the Interface zone, going up into the San Jacinto Mountains. In the WUI, efforts to prevent ignitions and limit wildfire loss hinge on hardening structures and creating defensible space through a multi-faceted approach, which includes engineering, enforcement, education, emergency response, and economic incentive. Different
Defining the Wildland-Urban Interface
As shown on Figure 6-9, the
wildland-urban interface is made
up of three distinct zones:
1. Intermix Zone. Housing
development or improved parcels
interspersed in an area dominated
by wildland vegetation subject to
wildfire.
2. Interface Zones. Dense
housing next to vegetation, but not
dominated by wildland vegetation,
that can burn in a wildfire.
3. Influence Zone. Wildfire-
susceptible vegetation within 1.5
miles from the wildland-urban
interface or wildland-urban intermix
zones.
Page 6-46 Palm Springs 2040 General Plan
strategies in the defense and threat zones of the WUI help to limit the spread of fire and reduce the risk to people and property. Increasing local and regional fire frequency can create recurring air quality degradation events leading to respiratory health effects. Wildfire smoke consists of a mix of gases and fine particulate matter from burning vegetation and materials. The pollutant of most concern from wildfire smoke is fine particulate matter (PM2.5). PM2.5 from wildfire smoke is damaging to human health due to its ability to deeply penetrate lung tissue and affect the heart and circulatory system. Although wildfire smoke presents a health risk to everyone, sensitive groups may experience more severe acute and chronic symptoms from exposure to wildfire smoke, such as children, older adults, people with chronic respiratory or cardiovascular disease, or people experiencing low socioeconomic status. Wildfire will continue to be a high-risk hazard for personal safety and property damage in Palm Springs, and smoke impacts from local and regional wildfires are likely to continue to be problematic.
Urban Fires Palm Springs is also at risk from urban fires. These fires occur in built-up environments, destroying buildings and other human-made structures. Structural fires are often due to faulty wiring or mechanical equipment and combustible construction materials. The absence of fire alarms and fire sprinkler systems are often conditions that exacerbate the damages associated with a structural fire. Structural fires are largely from human accidents, although deliberate fires (arson) may be a cause of some events. Older buildings that lack modern fire safety features may face greater risk of damage from fires. In newer residential areas where construction includes fire-resistant materials and interior fire sprinklers, most structural fires can be confined to the building or property of origin. To minimize fire damage and loss, the City’s Fire and Building Codes, based on the California Fire and Building Codes, set standards for building and construction. They require the provision of adequate water supply for firefighting, fire-retardant construction, minimum street widths, and defensible space requirements, among other things. The likelihood of structural fires in the city is lower than wildfires since these fires are usually associated with human accidents or mechanical issues in buildings that rarely happen.

Climate Change and Fire Hazards Changing climate conditions are expected to increase the fire risk in and around Palm Springs. Warmer temperatures brought on by climate change can exacerbate drought conditions. Droughts can kill or dry out plants in the mountainous areas of the city, creating more fuel for wildfires. Hot, dry spells may also increase disease and insect infestations resulting in higher fuel loads in juniper woodlands. Increased winds may result in more erratic fire behavior, making fires harder to contain. Warmer temperatures are also expected to occur during more of the year, extending the wildfire season, which is likely to begin earlier in the year and extend later than it has historically. Wildfires occurring later or earlier in the year are more likely to occur during Santa Ana wind events, which can cause wildfires to move more quickly and increase the likelihood of burning in the WUI areas.
Earthquake-Induced Fires Although wildland fires can be devastating, earthquake-induced
fires have the potential to generate the worst-case fire-suppression scenarios for a community because an earthquake typically causes multiple ignitions over a broad geographic area. If fire fighters are involved in search and rescue operations they are less available to fight fires, and the water distribution system could be impaired, limiting fire-suppression efforts even further. If earthquake-induced fires occur during Santa Ana wind conditions, the results can be far worse. There are some areas in Palm Springs where breaks in gas mains and the water distribution system caused by an earthquake could lead to a significant fire danger. A moderate to strong earthquake on any of the faults that affect the city could trigger multiple fires, disrupt lifelines services (such as the water supply), and trigger other geologic hazards, such as landslides or rockfalls, which could block roads and hinder disaster response. Therefore, the capacity of water systems to provide sufficient water to fight fires is a significant issue.

HAZARDOUS MATERIALS AND WASTE Palm Springs has many businesses that manufacture, transport, store, use, and dispose of hazardous materials. The city, therefore, has the potential to be affected by a major hazardous material emergency or affected in general by hazardous materials and waste. In Palm Springs are several identified hazardous or toxic materials sites associated with commercial, industrial, quasi-industrial, and medical operations and processes, which have the potential for accidental spills, purposeful illegal dumping, air emissions, and other uncontrolled discharges into the environment. Only one transporter of hazardous waste is listed by the EPA in the Palm Springs area. Most of the hazardous materials generators within the city are within five miles of the Garnet Hill and Banning Faults, which have a relatively high probability of generating an earthquake in the next 30 years. Several of the hazardous materials facilities have been identified as being located between the 100- and 500-year floodplain for the Whitewater River. Therefore, all of the hazardous materials sites within the city could be subject to moderate to severe seismic shaking or flooding.
Transport of Hazardous Materials State Highway 111, Interstate (I-)10, and the Union Pacific Railroad corridor are all used to transport hazardous materials through the city. These areas have the highest likelihood of potential spills or leaks. The California Highway Patrol coordinates response to spills in or along freeways, with Caltrans, local police departments, and fire departments responsible for providing additional enforcement and routing assistance. Additionally, natural gas transmission pipelines extend across the city and sphere of influence north of I-10. Rupture of any portion of these pipelines would adversely impact the area.
Surface and Subsurface Groundwater Contamination Other potential hazards to Palm Springs include groundwater and drinking-water pollution, leaking underground fuel tanks, household hazardous waste, and old landfill sites. The City of Palm Springs is a co-permittee and the local enforcing agency for the National Pollutant Discharge Elimination System
Page 6-56 Palm Springs 2040 General Plan
(NPDES). The NPDES requires the development, adoption, and implementation of plans and programs for stormwater management which prohibits non-stormwater runoff into storm drains and seeks to reduce and eliminate the discharge of pollutants to local groundwater and nearby bodies of water. The Desert Water Agency (DWA) provides drinking water to the City of Palm Springs. According to the EPA Safe Drinking Water Violation Report, the DWA has not had a health violation since 1993, the earliest date for which records are available. In accordance with the California Integrated Solid Waste Management Act of 1989, the Riverside County Department of Environmental Health, Hazardous Materials Management Division (DEH-HMMD) adopted a Household Hazardous Waste (HHW) program, called ABOP (antifreeze, batteries, oil, and paint) to promote the recovery and recycling of hazardous materials and prevent groundwater contamination. The City of Palm Springs participates in the program and has an HHW drop-off facility at the Palm Springs Fire Department Training Center, 3000 East Alejo Road. There are no active landfills in the Palm Springs area. Solid waste generated in Palm Springs is collected by the Palm Springs Disposal Service and deposited in the Edom Hill Transfer Station. Once sorted, solid waste is taken to the Lamb Canyon Landfill in Beaumont.
Hazardous Materials Management Plan In response to the need for safe management of hazardous materials and waste products, Riverside County, along with Palm Springs and other cities in the county, have jointly developed the Riverside County Hazardous Waste Management Plan (HWMP) to address the disposal, handling, processing, storage, and treatment of local hazardous materials and waste products. The Riverside County HWMP ensures that adequate treatment and disposal capacity will be available to manage the hazardous wastes generated within each jurisdiction. The Riverside County Department of Environmental Health, Hazardous Materials Division is the designated Certified Unified Program Agency for Riverside County and is responsible for coordinating hazardous material planning and response efforts with city departments as well as local and state agencies. The goal is to improve public and private sector readiness, and to reduce local impacts from hazardous materials and waste. The Hazardous

AIRPORT SAFETY Safety considerations for land uses immediately adjacent to the Palm Springs International Airport are especially important to the city. Figure 6-10, Airport Compatibility Plan, shows “compatibility zones,” or areas where take-off and landing patterns create risks for people living and working in the area. The Riverside County Airport Land Use Compatibility Plan (RCALUCP) designates zones of airport influence in the city and offers policies and criteria to ensure compatibility between airports and surrounding land uses. The RCALUCP provides Basic Compatibility Criteria, which include such considerations as the prohibition of tall structures, hazardous materials storage, siting of high-occupancy buildings and facilities, and critical infrastructure within compatibility zones, as well as limits on dwelling units per acre and regulatory procedures for approval of land uses. The Palm Springs International Airport Master Plan guides future development within the airport itself and offers useful information for determining aircraft-related risks and hazards. In addition, considerations for development around airports include the potential for noise nuisance, the intensity of development, and the height of structures. Refer to Figure 6-10 for areas impacted by height-review overlay zones and land use compatibility zones surrounding the Palm Springs International Airport. Goals and policies related to potential noise impacts created by the airport, as well as noise contours for the airport facility, can be found in the Noise Element. The Palm Springs Fire Department has provided Aircraft Rescue Fire Fighting (ARFF) services to the Palm Springs International Airport for over 60 years. Services provided include emergency medical services, fire protection services, fire protection planning, fire prevention, hazardous materials response, and public education.
Climate Change and Airport Safety Climate change is unlikely to substantially affect airport infrastructure safety. However, increase in the number of extreme heat days of 115 to 120 degrees Fahrenheit can decrease the density of the air, making it difficult for larger aircraft to take off. Higher temperatures can also warp the runway surface, making it difficult to land, and preventing electronic equipment from cooling, preventing aircraft from taking off. Therefore, extreme heat is likely to cause more frequent delays and closure events of the Palm Springs International Airport.

Although many private, gated communities have internal security for their residents, the Police Department still provides all law enforcement services . The Police Department’s two divisions, Operations and Support Services, employ 100 sworn and 49 civilian personnel. Operations include patrol, jail, and airport operations. Support services include investigation, records, animal control, and communications. Although National Census Bureau figures indicate that the Palm Springs population is approximately 44,575, the population increases significantly to approximately 75,000 when part-time residents and tourists are included in the winter months. In 2021, the department responded to 75,395 calls for service, an increase of approximately 35,000 calls since 2010.

The desired response times for priority one calls (emergencies) and priority two calls (nonemergencies) are 5 minutes and 30 minutes, respectively. The Palm Springs Police Department has mutual-aid agreements with other local law enforcement agencies in the event of a major incident that exceeds the department’s resources. There are currently six patrol beats (geographical patrol areas) serving the city and its sphere of influence in the northern portion of Palm Springs. As the city continues to grow, it will be necessary to expand the existing beat system and possibly add additional satellite field offices. Because of the mountains to the south and west of the city, communications between patrol units and officers using handheld radios can be poor Additional relay towers and communications equipment, particularly in the Palm Hills area and in the City’s northern Snow Creek area, would improve communications between patrol units and officers. The Department’s Community Policing Program seeks to enhance involvement with residents of Palm Springs to further promote public safety. The Citizens on Patrol (COP) Program extensively trains volunteers in such areas as traffic control, safe patrol techniques, CPR, and first aid. The Department’s Community Policing Program also operates the Citizen’s Police Academy, Alarm Diversion School, LGBTQ+ Outreach Committee, and the volunteer-based horseback Mounted Enforcement Unit, which consists of sworn police officers offering their time for high-visibility public events.
Fire Protection and Emergency Services The Palm Springs Fire Department, established in 1931, provides for fire, paramedic, and emergency services within the city limits and through mutual agreements in the City’s sphere of influence. The Fire Department is authorized and directed to enforce the provisions of the Fire Code throughout the city. Its responsibilities also include plan reviews for new construction and additions, coordination with the City for disaster preparedness programs, vegetation management, high fire area inspections, and the Hazardous Materials Business Program. The Palm Springs Fire Department, with a rating of ISO Class 3, protects 96 square miles of the Palm Springs area, constantly monitors fire hazards in the city, and has ongoing programs for investigation and alleviation of hazardous conditions.

In addition, the Palm Springs Fire Department strives to meet the National Fire Protection Association (NFPA ) Standard 1710 requirements for response time. NFPA 1710 requires that fire departments establish a six-minute response time for the first-due engine company 90 percent of the time, which includes one minute for dispatch, one minute for “turnout” in the station, and four minutes for travel to the incident. NFPA 1710 also requires an eight-minute response 90 percent of the time for a full-alarm assignment. There are a total of 21 on-duty firefighting personnel available during each 24-hour period. The Fire Department’s five stations responded to approximately 12,000 calls for service in 2021. Their records indicate that the number of responses has increased every year by approximately 5 to 7 percent. If needed, additional fire assistance can be provided by the following agencies and municipalities with whom Palm Springs has automatic- and mutual-aid agreements:
Riverside County Fire Department (RCFD) – mutual aid
United States Forest Service (USFS) – mutual aid
California Department of Forestry and Fire Protection (CAL FIRE) – mutual aid
Bureau of Land Management – mutual aid
Cathedral City – automatic aid The USFS, RCFD, CAL FIRE, and Bureau of Land Management generally respond to fire emergencies outside the city’s boundaries and in the sphere of influence. The Palm Springs Fire Department is primarily a structure-oriented protective force—these automatic- and mutual-aid agreements ensure an appropriate response to both urban and wildland fires.

CLIMATE CHANGE RESILIENCE In Palm Springs, climate change hazards include air quality, drought, extreme heat and warm nights, flooding, human health hazards, landslides, severe storms, and wildfires. This section provides background information, goals, and policies on the climate change not discussed previously in the Safety Element. Appendix X provides additional details about climate change hazards and the vulnerable populations and community assets in Palm Springs.
Air Quality The dominant sources of air pollution in Palm Springs are ozone pollution from vehicle exhaust and agricultural soils, fine particulate matter and dust from the Salton Sea, and smoke from wildfires in the region. Higher future temperatures will likely increase the production of ground-level ozone, especially in desert cities like Palm Springs, which already experience high levels of this pollutant. Ground-level ozone is associated with a variety of negative health outcomes, including reduced lung function, pneumonia, asthma, cardiovascular diseases, and premature death. As more frequent and severe drought and extreme heat occur in the region, the playa on the Salton Sea is expected to dry, increasing dust production and creating toxic airborne emissions in the region. Smoke from wildfires in the region can also increase air pollution levels and create a significant health risk in the region.

Drought is a recurring pattern in
California’s climate. The State
recently experienced the 5-year
drought event from 2012 to 2016.
Other notable historic droughts in
California include 2007 to 2009,
1987 to 1992, 1976 to 1977, and
off-and-on dry conditions spanning
more than a decade in the 1920s
and 1930s.

Drought A drought occurs when conditions are drier than normal for an extended period, making less water available for people and ecosystems. Drought is different than many of the other natural hazards in that it is not a distinct event and usually has a slow onset. Drought can severely impact a region both physically and economically, affecting different sectors in different ways and with varying intensities. Adequate water is the most critical issue for commercial and domestic use. As the population in the city continues to grow, so will the demand for water. Based on historical information, the occurrence of drought in California, including the Coachella Valley, is cyclical, driven by weather patterns. Drought has occurred in the past and will occur in the future. Periods of actual drought with adverse impacts can vary in duration, and the period between droughts is often extended. Although an area may be under an extended dry period, determining when it becomes a drought is based on impacts to individual water users. The impacts from drought include reduction in water supply and water quality. Palm Springs receives water from the Coachella Valley Water District, Desert Water Agency, and Mission Springs Water District through groundwater, purchased water, and recycled water sources. Based on the 2018 Coachella Valley Integrated Regional Water Management
Plan, the Coachella Valley obtains most of its water from the Colorado River, with small amounts from groundwater and recycled water sources. The water agencies have State Water Project allocations, but due to infrastructure limitations, these allocations are exchanged as part of an agreement with the Metropolitan Water District of Southern California for Colorado River water. The Colorado River experiences a reduction in water supply during drought conditions. This can cause water shortages and heavier reliance on groundwater supplies to meet the needs of Palm Springs residents and businesses. Each water district and agency providing water to Palm Springs has a Water Shortage Contingency Plan with specific demand reduction actions to conserve water and ensure reliable supplies. The price of water could, however, increase through drought rate surcharges, increasing the economic instability of low-income residents.
Page 6-68 Palm Springs 2040 General Plan
Extreme Heat and Warm Nights While there is no universal definition of extreme heat, California guidance documents define extreme heat as temperatures that are hotter than 98 percent of the historical high temperatures for the area, as measured between April and October of 1961 to 1990. Days that reach this level are called extreme heat days. In Palm Springs, an extreme heat day occurs when temperatures reach above 107.1 degrees Fahrenheit citywide. However, this threshold is approximately 113 to 115 degrees Fahrenheit in the more urbanized city center. According to Cal-Adapt, the number of extreme heat days in Palm Springs is projected to increase from a historic annual average of 4 extreme heat days per year to an average of 28 extreme heat days per year by midcentury and an average of 50 extreme heat days per year by the end of the century. Extreme heat can also occur in the form of warmer nights when temperatures do not cool enough overnight to provide relief from the heat. In Palm Springs, a warm night occurs when the temperature remains above 74.2 degrees Fahrenheit citywide. Similar to extreme heat, this threshold would be higher in the more urbanized city center of Palm Springs. The number of warm nights in Palm Springs is projected to increase from a historical annual average of 4 warm nights per year to an average of 32 warm nights per year by midcentury and an average of 64 warm nights per year by the end of the century. Although Palm Springs is accustomed to warmer temperatures, prolonged extreme heat and warm nights can cause heat-related illnesses, such as heat cramps, heat exhaustion, and heat stroke, in addition to exacerbating respiratory and cardiovascular conditions. Some homes in Palm Springs may lack central air conditioning, and as a result people living in these homes may be more susceptible to harm from extreme heat events. If homes have air conditioning, residents may find increased use cost prohibitive, especially for older or less efficient systems. Indirectly, extreme heat puts more stress on power lines, causing them to run less efficiently. The heat also causes more demand for electricity (usually to run air conditioning units), and in combination with the stress on the power lines, may lead to brownouts and blackouts.
Palm Springs 2040 General Plan Page 6-69
SAFETY ELEMENT
Human Health Hazards There are several diseases, such as hantavirus pulmonary syndrome, Lyme disease, West Nile virus, and influenza, that are linked to climate change and can be debilitating or fatal for some of the population. Pests such as mice, rats, ticks, and mosquitos carry these diseases. Climate change can increase the rates of infections because many of the animals that carry diseases are more active during warmer weather, and their populations may expand in size due to higher levels of rainfall during storm events and stagnant water after flooding, increasing the time for disease transmittal. Some diseases and illnesses have the potential to become epidemics or pandemics if they spread within communities, regions, or over multiple countries. Epidemics and pandemics, such as the COVID-19 pandemic, can worsen existing health conditions as well as cause economic disruptions in the city and region. Mental health and stress-related disorders also increase following natural disasters such as flooding or severe weather events.
Severe Storms Severe weather can include high winds, sandstorms, hail, and lightning, which are usually caused by intense storm systems, although high winds and sandstorms can occur without a storm, as discussed above in the Geologic Hazards section. While the connection between climate change and severe storms is not as well established as other hazards, new evidence suggests that these forms of severe weather may occur more often than in the past due to climate change. Severe winds, such as the Santa Ana winds, tend to be most frequent during October to April and can have average speeds of 40 miles per hour. These winds can destroy buildings, knock over trees, damage power lines and electrical equipment, and fan small sparks into large wildfires in the region. These winds can also pick up dust and other particulate matter from the desert or dry lakebed of the Salton Sea, causing sandstorms that lower visibility and cause toxic particulate matter to get into buildings. In severe instances, roadways can be blocked and other infrastructure damaged by a sandstorm. Severe storms can also bring heavy rainfall, which can lead to flash floods and ponding in areas of the city not protected by a levee. Though less common in the city, hail and lightning can damage the buildings and infrastructure supporting economic sectors and key services.
Page 6-70 Palm Springs 2040 General Plan
Key Population Vulnerabilities Climate change hazards that create the most vulnerabilities in Palm Springs include wildfire, extreme heat, and air quality. The most vulnerable populations include households with financial instability such as households in poverty; persons that spend an extended amount of time outdoors such as children and outdoor workers; persons with existing health conditions or limited mobility such as seniors or persons with chronic illnesses; and persons with language barriers and citizenship uncertainty.
Persons with financial instability are more likely to live in older homes with poor or inefficient insulation, less structural stability, or lack of efficient or reliable air conditioning. These conditions can increase exposure to unsafe living conditions due to mold and mildew damage from flooding, high indoor air temperatures from extreme heat and warm nights, and poor indoor air quality from air pollution and severe weather.
Persons that spend an extended amount of time outdoors could be directly exposed to poor air quality, extreme heat, human health hazards, and smoke from wildfires, causing illnesses or economic hardship.
Persons with existing health conditions or limited mobility may have difficulty preparing for or recovering from hazards, especially if evacuations are needed.
Persons with language barriers and citizenship uncertainty are more likely to live in less resilient structures and may be hesitant to seek help or may not qualify for financial assistance programs that can help them prepare and recover from a disaster. Other vulnerable populations include persons experiencing homelessness, as they may not have access or the ability to travel to safe shelters to hazardous events, in addition to persons living on single access roads, which could be blocked by landslides or wildfires preventing this population from evacuating. Appendix X provides a more detailed description on the population vulnerabilities in Palm Springs due to climate change hazards.

GOAL SA9:
A community resilient to climate-change-related hazards.
Policies SA9.1 Elevate extreme heat as an important hazard of concern in Palm Springs and respond to extreme temperatures. SA9.2 Coordinate with SunLine Transit Agency and regional transit providers to identify alternate routes and stops if normal infrastructure is damaged or closed as a result of severe storms or flooding. SA9.3 Coordinate with Southern California Edison and Desert Clean Energy to incentivize residential and on-site solar systems, especially when paired with battery storage to provide a resilient energy supply for homes. SA9.4 Coordinate with County of Riverside Public Health to ensure emergency and public health services can meet the needs of the population during extreme heat, poor air quality, and human health hazard events. SA9.5 Increase the resiliency of City-owned structures to severe storm events and support homeowners and business owners to increase the resilience of their buildings and properties through retrofits, weatherization, and other improvements. SA9.6 Collaborate with Southern California Edison to underground electrical transmission infrastructure throughout the city, prioritizing high voltage transmission lines and areas in Very High Fire Hazard Severity Zones and the Wildland Urban Interface. SA9.7 Promote and expand the use of drought-tolerant green infrastructure, including street trees and landscaped areas, as part of cooling strategies in public and private spaces. SA9.8 Prepare for more frequent and severe drought events by working with regional water providers to implement extensive water conservation measures and ensure sustainable water supplies.
Page 6-72 Palm Springs 2040 General Plan
SA9.9 Encourage businesses that have outdoor workers to allow for shifting in work hours to earlier in the day from May through September to reduce heat-related illnesses among outdoor workers on extreme heat days. SA9.10 Prepare for more frequent and severe drought events by working with Desert Water Agency and other regional water providers to implement extensive water conservation measures and ensure sustainable water supplies. SA9.11 Encourage new developments and existing property owners to incorporate sustainable, energy-efficient, and environmentally regenerative features into their facilities, landscapes, and structures to reduce energy demands and improve on-site resilience. Support financing efforts to increase the communities funding of these features. SA9.12 Where feasible, encourage the use or restoration of existing natural features and ecosystem processes when considering alternatives for the conservation, preservation, or sustainable management of open space. This may include, but is not limited to, aquatic or terrestrial vegetated open space, systems and practices that use or mimic natural processes, and other engineered systems to provide clean water, conserve ecosystem values and functions, and provide a wide array of benefits to people and wildlife. SA9.13 Collaborate with Southern California Edison, Desert Clean Energy, and organizations such as the Community Access Center to ensure that those who depend on electricity supply for medical devices and refrigerating medication have backup energy supplies during extreme heat and extreme wind events. SA9.14 Look for opportunities to ensure that workers in outdoor industries have the training and resources to be adequately protected from environmental hazards, including extreme heat, poor air quality, pests, and diseases. SA9.15 Collaborate with Riverside County Department of Public Health and healthcare providers to prepare for disasters and health emergencies, minimizing disruptions to medical services and facilities in Palm Springs.

SAFETY ELEMENT
MULTIPLE NATURAL HAZARDS Due to the location in an earthquake prone region, floodplains, wildfire prone area, and steep topography, Palm Springs is in an area that can experience multiple, simultaneous natural hazards. These can also be called compounding hazards or cascading hazards. Compounding hazards could include a flood event that is followed by earthquake, which are unrelated events that could compound to increase liquefaction in soils near floodplains. Cascading hazards, on the other hand, occur one after the other. For example, an increase in extreme heat events and drought can dry out juniper woodlands in the San Jacinto Mountains, leading to more fuel for wildfire, which can lead to a faster moving and higher burning wildfire. The burn scar of that wildfire could then experience heavy rainfall, which could lead to a landslide, rockfall, or debris flow. This cascading of hazards is shown on Figure 6-11. All of these hazards are discussed separately above, but when combined, these hazards can cause more devastating consequences for Palm Springs residents, visitors, and businesses.
Figure 6-11. Example of Cascading Hazards
Increase in extreme heat events and drought can dry out juniper woodlands. More fuel for fires development in the San Jacinto Mountains.
Wildfires spread faster and burn hotter.
Wildfires burn the vegetation supporting the slopes on the mountainside. Heavy rainfall or an earthquake cause the unstable slope to form into a landslide, debris flow, or rock fall.
Compounding Hazards: Events
where more than one hazard
occurs at the same time and
interact to cause more destructive
consequences.
Cascading Hazards: Extreme
events that link together hazards
over days, weeks, or months,
resulting in multiplied effects that
cause secondary and sometimes
tertiary damage, exceeding the
damage of the initial hazard event.
Page 6-74 Palm Springs 2040 General Plan
GOAL SA10:
A community prepared for multiple natural hazards.
Policies SA10.1 Require that proposed essential, sensitive, and high-occupancy facilities undergo careful seismic, geologic, flooding, and fire review prior to any approvals and that effective post-disaster functioning be a primary concern in the siting, design, and construction standards for essential facilities. SA10.2 Minimize the risk to life and property through the identification of potentially hazardous areas, adherence to proper construction design criteria, and provision of hazards information to all residents and business owners. SA10.3 Where appropriate, designate hazard zones as open space (earthquake fault lines, floodways and floodplains, steep or unstable slopes, areas susceptible to rockfalls and landslides, wildfire prone areas, etc.) and update these areas on the land use map. SA10.4 Encourage and cooperate with Caltrans to stabilize susceptible slopes and strengthen bridges, elevated roadways, and other structures along state highways that may be subject to failure during major hazardous events, thereby isolating portions of the community from emergency aid and assistance. SA10.5 Provide protection for roadways and utility lines from all applicable hazard conditions to ensure they remain open for evacuation needs. SA10.6 Continue to use the Emergency Announcement System to implement hazard warnings and evacuation plans for those portions of the city in flood hazard zones, wildfire- and landslide-prone areas, and seismically active areas that have already been inhabited or developed and for critical facilities such as schools.

PALM SPRINGS SAFETY ELEMENT | DRAFT IMPLEMENTATION PROGRAMS
September 2024
This section serves as a working checklist of implementation programs for City staff and local decision makers to ensure that the General Plan
vision is realized. The following table of Implementation Programs lists specific actions that should be pursued to implement each goal and policy
in the City’s General Plan. An implementation program is an action, procedure, program, or technique that carries out goals and policies.
Implementation measures are comprehensive in nature, encompassing amendments of existing and preparation of new plans, ordinances, and
development of design standards; administration of City procedures and development review and approval processes; and interagency
coordination.
For each action, a recommended timeframe for completion is noted and the responsible City department is listed. The timeframes are
delineated as follows:
Ongoing: Actions that continue or are periodically implemented through the life of the General Plan
Short: 1-5 years
Mid: When resources become available, but prioritized after 5 years
Long: 10 years or more
The described programs and actions are intended to inform and guide the development of the City’s annual budget. During that time, City staff
will review and prioritize the level of expenditure necessary to carry out the prescribed action and program. Completion of a recommended
implementation program will depend on a number of factors such as citizen priorities, finances, and staff availability.
To enable Palm Springs’ General Plan to serve its purpose effectively, the list of programs and actions need to be reviewed, maintained, and
implemented in a systematic and consistent manner. At a minimum, the programs and timeframes described in this chapter should be
comprehensively reviewed and updated at least once every five (5) years to reflect available fiscal resources, community needs, and priorities.
Revisions to these shall not constitute an amendment of the General Plan, provided that they are consistent with the Vision Statement and carry
out its goals and policies. As such, future revisions to this Implementation Plan will not necessitate environmental review to conform to
California Environmental Quality Act (CEQA) requirements, as each item described in this Plan will require subsequent action and evaluation.

CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 3
INTRODUCTION
The City of Palm Springs (City) prepared this Vulnerability Assessment Report in conformance with State
of California requirements to assess climate change vulnerability and address climate change adaptation
and resilience as part of the General Plan Update (California Government Code Section 65302(g)). The
goal of this requirement is to enable the community to prepare for, respond to, withstand, and recover
from disruptions created or caused by climate change. This report discusses the regulatory framework
and method for preparing a vulnerability assessment and incorporating adaptation and resilience into the
General Plan, the climate change hazards affecting the resilience of Palm Springs, specific populations and
assets in the assessment, and a summary of the vulnerability assessment results. The vulnerability
assessment is a foundation for integrating adaptation and resilience policies into the Safety Element and
General Plan by identifying a set of priority vulnerabilities in Palm Springs. These policies and programs
are discussed in the “Implications for the General Plan Update” section.
Community Profile
Palm Springs is in the northern portion of Coachella Valley, surrounded by the San Bernardino Mountains
to the north, the Little San Bernardino Mountains and the Sonoran Desert to the east, the Santa Rosa
Mountains to the south, and the San Jacinto Mountains to the west. The San Jacinto Mountains rise
nearly 10,850 feet above sea level, and the city sits under this mountain range at 479 feet above sea
level. The city has a desert climate, with little rain and hot summers. According to the 2020 Decennial
Census, Palm Springs is home to approximately 44,575 residents, more than 50 percent of which are over
55 years old.
The city covers approximately 94 square miles, as shown in Figure 1, that was originally home to the Agua
Caliente Band of Cahuilla Indians. Only about 20 square miles in central Palm Springs is developed; the
northern area of the city is primarily dedicated to wind and solar energy production and recreation
activities, and the southern area is dedicated to open space and recreational activities. The Agua Caliente
Band of Cahuilla Indians currently represents the largest single landowner in Palm Springs. Land uses
within the urban development of the city consist of a mix of residential single-family homes, visitor
lodging, commercial property, and leisure- and recreation-focused properties.
On average, annual high temperatures in Palm Springs range from 69 degrees Fahrenheit in December to
108 degrees Fahrenheit in July. Low temperatures range from 44 degrees Fahrenheit in December to 78
degrees Fahrenheit in July and August. The city receives an average of approximately 4.83 inches of
precipitation per year, with some precipitation falling as snow in the San Jacinto Mountain range. Most
precipitation falls during the winter months, with rare summer storms. Temperatures above 90 degrees
Fahrenheit or higher have been recorded in all months of the year. The warm desert setting and mild
winter makes Palm Springs a desirable location for senior residents and visitors seeking to spend time in
the San Jacinto Mountains or Joshua Tree National Park.

Palm Springs’ primary transportation access is from State Route 111 (SR-111) via Interstate 10 (I-10), the
primary highway in the Coachella Valley. I-10 runs west through Riverside County to downtown Los
Angeles and east through the southern United State to the east coast. SR-111 runs through Palm Springs,
connecting the city to I-10 in the north and the Salton Sea to the south. Other major roadways include
Palm Canyon Drive and Indian Canyon Drive, which run through downtown Palm Springs and the
southern portion of the urban area. Since 2013, the City has installed 69 electric-vehicle charging stations
along many of the major roadways and commercial centers, including a high-speed charging station at
the Visitors Center. Palm Springs International Airport is in the eastern part of the city. The SunLine
Transit Agency operates three routes through Palm Springs that residents and visitors can use to travel
around Palm Springs and to other areas of Coachella Valley. Amtrak provides long-distance train service
via Palm Springs to Los Angeles, Chicago, and New Orleans. The City also maintains a robust bike and
pedestrian network that includes six loops, the Gene Autry bikeway, and the Whitewater trail as well as
several bike paths, lanes, and routes.
Regulatory Framework
In 2015, the State adopted Senate Bill (SB) 379, amending Section 65302(g) of the California Government
Code to require the Safety Element of the General Plan to include more information about wildfire
hazards, flooding risks, and other short-term and long-term threats posed by climate change. SB 379 is
the foundation for adaptation and resiliency in general plan safety elements because it requires local
governments to conduct vulnerability assessments as part of their long-range public safety planning
efforts and to prepare adaptation and resilience goals, policies, and implementation measures that
respond to the findings of the Vulnerability Assessment and protect against harm caused by climate
change.
Other important updates to California Government Code Section 65302(g) related to safety elements are
SB 1035 and SB 99. SB 1035, which establishes Section 65302(g)(6) of the California Government Code,
builds on previous legislation, and requires local governments to review and update as needed their
safety element during an update to their housing element or Local Hazard Mitigation Plan (or no less than
every eight years). Any revisions should include updated information related to flood hazards, fire
hazards, and climate adaptation and resilience. SB 99 established Section 65302(g)(5) of the California
Government Code and requires jurisdictions to review and update the safety element to include
information identifying residential developments in hazard areas that do not have at least two emergency
evacuation routes. This vulnerability assessment, along with the update to the Safety Element, will help
the City of Palm Springs meet the state’s requirements and increase consistency with the 2017 City of
Palm Springs Local Hazard Mitigation Plan.
The California Governor’s Office of Emergency Services prepared a guidance document, the California
Adaptation Planning Guide, to assist communities in addressing climate adaptation and resilience, and
complying with Section 65302(g) of the California Government Code. This guide presents a step-by-step
process for gathering the best available climate change science, completing a climate change vulnerability
assessment, creating adaptation strategies, and integrating those strategies into general plans and other
policy documents. The City’s vulnerability assessment is consistent with the guidance and recommended
methods in the California Adaptation Planning Guide.

Climate Science Overview
Climate change is a long-term change in the average meteorological conditions in an area. Currently, the
global climate is changing due to an increase in greenhouse gas (GHG) emissions that trap heat near the
Earth’s surface. Though certain levels of GHGs are necessary to maintain a comfortable temperature on
Earth, an increased concentration due to human activity traps additional heat, changing Earth’s climate
system in several ways. These effects cause primary climate stressors, which include warmer
temperatures and changes in precipitation patterns, which can cause and exacerbate secondary climate
stressors. Secondary climate stressors, also known as climate change hazards, can include flooding,
severe weather, wildfires, landslides, drought conditions, and others. According to the California
Adaptation Planning Guide, these hazards have the potential to cause fatalities, injuries, property and
infrastructure damage, interruption of business, and other types of harm or loss. This Vulnerability
Assessment Report evaluates the impacts created by climate change hazards, the ability of Palm Springs’
populations and community to resist these hazards, and which aspects of the community are most
vulnerable to climate change.
Method
The Vulnerability Assessment analyzes how a changing climate could harm Palm Springs and which
aspects of the community—e.g., people, buildings and infrastructure, services, and economic drivers—
are most vulnerable to its effects. The vulnerability assessment primarily follows the recommended, four-
step process in the California Adaptation Planning Guide: (1) characterize the community’s exposure to
current and projected climate hazards; (2) identify potential sensitivities and potential impacts to
community populations and assets; (3) evaluate the current ability of the populations and assets to cope
with climate impacts, also referred to as its adaptive capacity; and (4) identify priority vulnerabilities
based on systematic scoring. Figure 2 shows these steps.
Figure 2. California Adaptation Planning Guide’s Recommended Method
Step 1: Identify Exposure. The goal of this step is to characterize the community’s exposure to current
and projected climate change hazards. Many projections of climate change hazards rely on multiple
scenarios that reflect different levels of how global GHG emissions and atmospheric GHG concentrations
may change over time. The Intergovernmental Panel on Climate Change (IPCC), an organization that
represents the global scientific consensus about climate change, has identified four climate scenarios, or
Representative Concentration Pathways (RCP), that can be used to project future conditions. RCPs are
labeled with different numbers (e.g., RCP 2.6, RCP 6) that refer to the increase in the amount of energy
that reaches each square meter of Earth’s surface under that scenario. The four RCPs are:
Step 1. Identify Exposure
Step 2. Identify Sensitivities and Potential Impacts
Step 3. Assess Adaptive Capacity
Step 4. Prioritize Vulnerability Scoring
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 7
• RCP 2.6: Global GHG emissions peak around 2020
and then decline quickly.
• RCP 4.5: Global GHG emissions peak around 2040
and then decline.
• RCP 6: Global emissions continue to rise until the
middle of the century.
• RCP 8.5: Global emissions continue to increase at
least until the end of the century.
The Cal-Adapt database, which provides California-specific climate change hazard projections, uses RCP
4.5 for a low emissions scenario and RCP 8.5 for a high emissions scenario. The California Adaptation
Planning Guide and the Governor’s Office of Planning and Research’s Planning and Investing for a
Resilient California recommend using RCP 8.5 for analyses that consider impacts through 2050 because
there are minimal differences between emission scenarios for the first half of the century. The California
Adaptation Planning Guide also recommends using RCP 8.5 for late-century projections for a more
conservative and risk-adverse approach. The City input the RCP 8.5 GHG emission scenario into global
climate models on the Cal-Adapt database and other resources.*
The first step of this vulnerability assessment was to confirm which climate change hazards are expected
to affect Palm Springs. The City identified eight climate change hazards for this assessment that are
discussed in more detail in Section 2.
1. Air Quality
2. Drought
3. Extreme Heat and Warm Nights
4. Flooding
5. Human Health Hazards
6. Landslides
7. Severe Weather
8. Wildfire
The City derived the climate change hazard data from up-to-date information, including the state Cal-
Adapt database, the California Adaptation Planning Guide, the California 4th Climate Change Assessment,
the California Geologic Survey, the Federal Emergency Management Agency, and the California Board of
Forestry and Fire Protection.
* The IPCC recently released “The Physical Science Basis” of the Sixth Assessment Report that updates global climate
change projections for the near term, midterm, and long term based on greenhouse gas emission trends from the
past decade. It moves away from using RCPs, instead using five different scenarios called “shared socioeconomic
pathways,” which consider socioeconomic trends underlying each scenario. This Vulnerability Assessment does not
use these updated projections because at time of writing they are not available at a local scale. However, the IPCC
report does reaffirm the use of projections comparable to RCP 8.5 as the suggested emission scenario to use for Cal-
Adapt data.

resources in areas that are subject to

VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 8
Step 2. Identify Sensitivities and Potential Impacts. This step
included evaluating past and potential future climate
change impacts to community populations and assets. The
City first identified a list of populations and assets to
include in the assessment under the following six
categories:
1. Populations: People that experience a heightened
risk or increased sensitivity to climate change or
have a lower capacity or fewer resources to adapt
to or recover from climate impacts.
2. Infrastructure: Structures that provide essential
services to Palm Springs community members and visitors.
3. Buildings: Homes, nonresidential buildings, and other building types.
4. Important Economic Assets: Properties and activities that make significant contributions to the
Palm Springs economy.
5. Ecosystems and Natural Resources: Types of wild and natural lands within the city boundary.
6. Key Community Services: Important and essential functions to community members provided by
government agencies and private companies.
The list included 17 populations, 19 infrastructure types, 10 building types, 6 economic assets,
5 ecosystems and natural resources, and 9 key community services. After confirmation of the list, the City
looked at which hazards are likely to affect which populations and assets, because not all hazards affect
all populations or assets. For example, human health hazards are likely to impact most populations, but
they would not physically affect community parks or school buildings.
The outcome of this step was an applicability review that identified whether a population or asset is likely
to be exposed to a hazard. If a population or asset has the potential to be affected directly or indirectly by
a hazard, the City confirmed it for inclusion in the vulnerability assessment. Direct impacts affect buildings
and infrastructure, health or populations, or immediate operations of economic drivers or community
services, and they can lead to indirect impacts on the broader system or community, including
populations or asset types in a different category. For example, severe weather can directly damage
electrical transmission lines, causing power outages, and thus indirectly impact persons with chronic
illnesses who depend on electricity for life support systems. Therefore, both electrical transmission lines
and persons with chronic illnesses would be marked “yes” for being affected by severe weather and
would be evaluated in the assessment.
After the applicability review, the City evaluated potential impacts to the applicable populations and
community assets. To identify the magnitude of each relevant hazard’s impacts on the populations and
community assets, the City considered a number of different questions that helped ensure the
assessment covered a broad range of potential harm. Examples of these questions include:
• Could the hazards cause injury or damage? Is there a risk of behavioral or mental harm, loss of
economic activity, or other nonphysical effects?
• How many people or community assets could be harmed both directly and indirectly?
• How long would the impacts persist?
• Is there a substantial chance of death or widespread destruction?
Sensitivity: The level to which a species,
natural system, community,
government, etc., would be affected by
changing climate conditions.
Impact: The effects (especially the
negative effects) of a hazard or other
conditions associated with climate
change.

Based on the results of the impact assessment, the City ranked each sensitivity on a five-point scale (0 to
4) for each relevant exposure. IM0 is the lowest impact, and IM4 is the highest impact. Impact is
considered a negative quality, and therefore a higher impact score means that there is a higher potential
for harm to a population or asset. A lower impact score means that there is a lower potential for harm to
a population or asset. Table 1 provides more detail about what each score means.
Table 1. Rubric for Impact Scoring
Impact Score Meaning (People and Ecosystems) Meaning (Buildings, Infrastructure, Services,
and Economic Drivers)
IM0. Minimal
Impact
Community members may not notice any
change.
Damage, interruption in service, or impact on
the local economy is small or intermittent
enough to mostly go unnoticed.
IM1. Low Impact
Community members notice minor effects.
Daily life may experience mild, occasional
disruptions.
There are minor but noticeable interruptions
in service, damage, or negative effects on the
economy.
IM2. Moderate
Impact
There is a marked impact to the community.
Quality of life may decline. Impacts may be
chronic, and at times substantial.
Damage, service interruptions, and other
impacts are clearly evident. Impacts may be
chronic and occasionally substantial.
IM3. Significant
Impact
The well-being of the community declines
significantly. The community’s current
lifestyle and behavior may no longer be
possible.
Impacts are chronic. Buildings, infrastructure,
and services may be often or always unable to
meet community demand. Large sections of
the economy experience major hardships.
IM4. Severe
Impact
There is a severe risk of widespread injury or
death to people, or of significant or total
ecosystem loss.
Buildings, infrastructure, and services cannot
function as intended or needed. Economic
activities are not viable.
Step 3. Assess Adaptive Capacity. Adaptive capacity is the
ability of populations and community assets to prepare for,
respond to, and recover from the impacts of climate
change. The City evaluated each population and asset for
adaptive capacity by considering the following questions:
1. Are there existing programs, policies, or funding to
provide assistance?
2. Are there barriers that limit response or recovery?
Are these barriers financial limitations, political
challenges, lack of access to technology or other
resources, or others?
3. Do alternatives exist in or near Palm Springs that community members can use?
Based on the results of the adaptive capacity assessment, the City ranked each population or asset on a
five-point scale (0 to 4) ranging from AC0 (the lowest adaptive capacity) to AC4 (the highest adaptive
capacity).
Adaptive Capacity: The “combination
of the strengths, attributes, and
resources available to an individual,
community, society, or organization
that can be used to prepare for and
undertake actions to reduce adverse
impacts, moderate harm, or exploit
beneficial opportunities”.
Source: California Adaptation Planning Guide
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 10
Adaptive capacity is considered a positive attribute, so a higher adaptive capacity score means that a
population or asset may be more adaptable to the hazard. A lower adaptive capacity score means that a
population or asset may have a harder time adjusting to the changing conditions. Table 2 provides more
detail about what each score means.
Table 2. Rubric for Adaptive Capacity Scoring
Step 4. Prioritize Vulnerability Scoring. The City used the
impact and adaptive capacity scores for each population and
asset for each relevant hazard to determine the vulnerability
score. The vulnerability (V) score reflects how susceptible the
population or asset is to harm from a particular hazard.
Vulnerability is assessed on a scale of 1 to 5, as shown in Figure
3. The matrix below (Table 3) shows how impact and adaptive
capacity scores combine and translate into a vulnerability
score. For example, extreme heat would create a significant
impact (IM3) on energy delivery because mechanical failures,
heat damage, and high demand for electricity from cooling
equipment can disrupt this service. Adaptive capacity is low (AC1) because many community members
need to use more electricity on extreme heat days to keep cool, and retrofitting electrical equipment can
be expensive. Therefore, energy delivery services are severely vulnerable (V5) to extreme heat.
Adaptive Capacity Score Meaning
AC0. No Adaptive Capacity Currently, there are no feasible means of adapting.
AC1. Low Adaptive Capacity
Adaptive solutions are available, but they are expensive, technologically difficult,
and/or politically unpopular. Alternatives may not exist that can provide similar
services.
AC2. Some Adaptive Capacity
Some adaptation methods are available, but not always feasible. Adapting may
create significant challenges for some sensitivities. Some alternatives exist within
community or nearby that can provide similar services.
AC3. High Adaptive Capacity
Adaptation solutions are feasible for most or all sensitivities. There may be
occasional or small-scale challenges to implementing adaptation methods. Many
alternatives exist in the area that can provide similar services.
AC4. Outstanding Adaptive
Capacity
Sensitivities can adapt with little or no effort. Quality of life is unchanged or may
improve.

CLIMATE CHANGE HAZARDS
As described in the California Adaptation Planning Guide, hazards are events or physical conditions that
have the potential to cause fatalities, injuries, property and infrastructure damage, interruption of
business, and other types of harm or loss. Some natural hazards are not related to climate change, such
as earthquakes, which do not have a known connection with climate change. Climate change hazards
focus on natural hazards that can change in frequency and intensity due to climate change. The
Vulnerability Assessment assessed the climate change hazards that are most relevant to the City of Palm
Springs. This section discusses the climate change hazards based on projections provided by Cal-Adapt,
the California Fourth Climate Change Assessment, the City of Palm Springs Local Hazard Mitigation Plan,
the Federal Emergency Management Agency, and scholarly research.
Air Quality
The dominant sources of air pollution in Palm Springs are ozone pollution from vehicle exhaust and
agricultural soils, fine particulate matter and dust from the Salton Sea, and smoke from wildfires in the
region. Higher future temperatures will likely increase the production of ground-level ozone, especially in
desert cities like Palm Springs, which already experience high levels of this pollutant. Ground-level ozone
is associated with a variety of negative health outcomes, including reduced lung function, pneumonia,
asthma, cardiovascular diseases, and premature death. As more frequent and severe drought and
extreme heat occur in the region, the playa on the Salton Sea is expected to dry, increasing dust
production and creating toxic airborne emissions in the region. Smoke from wildfires in the region can
also increase air pollution levels and create a significant health risk in the region.
Drought
A drought occurs when conditions are drier than normal for an extended period, making less water
available for people and ecosystems. Droughts are a regular occurrence in California; however, scientists
expect that climate change will lead to more frequent and more intense droughts statewide. According to
the U.S. Drought Monitor, Riverside County and Palm Springs are in severe drought conditions, and much
of California is in extreme or exceptional drought conditions. Palm Springs receives water from the
Coachella Valley Water District, Desert Water Agency, and Mission Springs Water District through
groundwater, purchased water, and recycled water sources. Based on the 2018 Coachella Valley
Integrated Regional Water Management Plan, the Coachella Valley obtains most of its water from the
Colorado River, with small amounts from groundwater and recycled water sources. The water agencies
have State Water Project allocations, but due to infrastructure limitations, these allocations are
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 12
exchanged as part of an agreement with the Metropolitan Water District of Southern California for
Colorado River water. The Colorado River experiences a reduction in water supply during drought
conditions. This can cause water shortages and heavier reliance on groundwater supplies to meet the
needs of Palm Springs residents and businesses. The water districts and agencies providing water to Palm
Springs each has a Water Shortage Contingency Plan with specific demand reduction actions to conserve
water and ensure reliable supplies. The price of water could, however, increase through drought rate
surcharges, increasing the economic instability of low-income residents.
Extreme Heat and Warm Nights
Extreme heat occurs when temperatures rise significantly above normal levels. In Palm Springs, an
extreme heat day occurs when temperatures reach above 107.1 degrees Fahrenheit. As shown in
Figure 4, the number of extreme heat days in Palm Springs is projected to increase from a historic annual
average of 4 extreme heat days per year to an average of 28 extreme heat days per year by midcentury
and an average of 50 extreme heat days per year by end of century.
Figure 4. Projected Extreme Heat Days in Palm Springs
Extreme heat can also occur in the form of warmer nights when temperatures do not cool enough
overnight to provide relief from the heat. In Palm Springs, a warm night occurs when the temperature
remains above 74.2 degrees Fahrenheit. As shown in Figure 5, the number of warm nights in Palm Springs
is projected to increase from a historic annual average of 4 warm nights per year to an average of 32
warm nights per year by midcentury and an average of 64 warm nights per year by the end of the
century.

Figure 5. Projected Warm Nights in Palm Springs
Extreme heat can cause heat-related illnesses, such as heat cramps, heat exhaustion, and heat stroke, in
addition to exacerbating respiratory and cardiovascular conditions. Some homes in Palm Springs may lack
air conditioning, and as a result people living in these homes may be more susceptible to harm from
extreme heat events. If homes have air conditioning, residents may find increased use cost prohibitive,
especially for older or less efficient systems. Some types of infrastructure, including power lines and
roadways, face greater stresses during high temperatures that make failure more likely.
Flooding
Flooding can cause significant harm to buildings, people, and infrastructure. Floodwater can be deep
enough to drown people and can move fast enough to carry away people or heavy objects (such as cars).
Flooding can be caused by heavy rainfall, extended periods of moderate rainfall, or clogged drains during
periods of rainfall. In rare instances, a break in a dam, water pipe, or water tank can also cause flooding.
Flash floods are floods that develop very quickly, and they can be especially dangerous because they give
little or no warning. Persons experiencing homelessness and others who may be outdoors in the path of a
flood can face particularly high risks from these events.
Storm drainage systems throughout the city collect stormwater runoff and convey water to prevent
flooding, although these systems are typically designed based on winter storms recorded in the past and
may not be designed to accommodate more intense storms. Scientists project that climate change will
increase the frequency and intensity of floods in Palm Springs, although total annual precipitation levels
are only expected to increase slightly. Figure 6 shows the FEMA-designated flood hazard areas in Palm
Springs.

Human Health Hazards
There are several diseases, such as hantavirus pulmonary syndrome, Lyme disease, West Nile virus, and
influenza, that are linked to climate change and can be debilitating or fatal for some of the population.
Pests such as mice, rats, ticks, and mosquitos carry these diseases. Climate change can increase the rates
of infections because many of the animals that carry diseases are more active during warmer weather,
and their populations may expand in size due to higher levels of rainfall during storm events and stagnant
water after flooding, increasing the time for disease transmittal. Some diseases and illnesses have the
potential to become epidemics or pandemics if they spread within communities, regions, or over multiple
countries. Epidemics and pandemics, such as the COVID-19 pandemic, can worsen existing health
conditions as well as cause economic disruptions in the city and region. Mental health and stress-related
disorders also increase following natural disasters such as flooding or severe weather events. The City
evaluated health hazards from air pollutants as part of the air quality hazard discussion.
Landslides
Landslides occur when a mountainside becomes unstable, causing soil and rocks to slide downslope.
Landslides can include rock falls, deep failures of slopes, and shallow debris flows. Landslides are most
common on steep slopes and mountainsides made up of loose soil or other material where excavation
and grading, drainage alterations, or changes in vegetation have occurred. The vulnerability assessment
looks at landslides that are caused by precipitation, although earthquakes can also trigger landslides.
Mountainsides commonly absorb water, which increases instability of the slope and may increase the risk
of slope failure. Steep slopes made of loose or fractured material are more likely to slide. In some cases,
hillsides become so saturated that slope failures result in a mudslide (a mixture of soil and water moving
downslope). As shown in Figure 7, steeper slopes in the San Jacinto Mountain range are in high landslide
susceptibility areas, and the flatter, urban area of Palm Springs is outside of this zone. Landslides and
mudslides can move fast enough to damage or destroy homes or other structures in their path, block
roadways (including evacuation routes), and injure or kill people caught in them.

Severe Storms
Severe weather can include high winds, sandstorms, hail, and lightning, which are usually caused by
intense storm systems, although high winds and sandstorms can occur without a storm. As described in
the Inland Desert Summary Report from the California Fourth Climate Change Assessment, the
connection between climate change and severe storms is not as well established as other hazards, but
new evidence suggests that these forms of severe weather may occur more often than in the past.
Severe winds, such as the Santa Ana winds, tend to be most frequent during October to April and can
have average speeds of 40 miles per hour. These winds can destroy buildings, knock over trees, damage
power lines and electrical equipment, and fan small sparks into large wildfires in the region. These winds
can also pick up dust and other particulate matter from the desert or dry lakebed of the Salton Sea—
known as “blowsand” or “windblown sand”—causing sandstorms that lower visibility and cause toxic
particulate matter to get into buildings. In severe instances, roadways can be blocked, and other
infrastructure can be damaged by a sandstorm. Severe storms can also bring heavy rainfall, which can
lead to flash floods and ponding in areas of the city not protected by a levee. Though less common in the
city, hail and lightning can damage the buildings and infrastructure supporting economic sectors and key
services.
Wildfire
Wildfires are a regular feature of the landscape in much of California. They can be sparked by lightning,
malfunctioning equipment, vehicle crashes, and many other causes. Warmer temperatures, an increase in
drought conditions, and extreme wind events are likely to create more fuel for fires in natural and rural
areas, leading to a greater chance that a spark will grow into a dangerous blaze. Climate change is also
expected to extend the fire season throughout much (or even all) of the year. Figure 8 shows the fire
hazard severity zones surrounding Palm Springs to the west and south in the San Jacinto Mountain. Three
major wildfires have occurred near the city in recent decades: the Dry Falls fire in 1980, the Palm fire in
1994, and the Mountain fire in 2013. Figure 9 shows the historic wildfire perimeters in and surrounding
Palm Springs. Because wildfires burn the trees and other vegetation that help stabilize a hillside and
absorb water, more areas burned by fire may also lead to an increase in landslides and debris flows.

POPULATIONS AND ASSETS
Populations and assets are the people, infrastructure, services, and economic drivers in Palm Springs that
can be affected by climate change. The vulnerability assessment looks at how each population and
community asset may be affected by each of the climate change hazards discussed in Section 2. The
California Adaptation Planning Guide provides a general list of populations and assets, which the City of
Palm Springs refined and used to develop six distinct asset categories: (1) populations, (2) buildings, (3)
infrastructure, (4) important economic assets, (5) ecosystems and natural resources, and (6) key
community services. In total, Palm Springs identified 66 distinct populations and assets, as shown in
Table 4. Figure 1 shows the location of key community and critical facilities for the vulnerability
assessment.

VULNERABILITY ASSESSMENT RESULTS
The vulnerability assessment evaluates the impact and adaptive capacity of each population and asset for
each relevant hazard. The City assigned vulnerability scores on a scale of 1 to 5 (as shown in Figure 2) to
reflect how susceptible the population or asset is to harm posed by the hazard. In total, the City assessed
357 different pairings for vulnerability. This section provides a summary of the key vulnerabilities in Palm
Springs. For a complete list of vulnerability scores for all populations and assets, see Appendix A.
Population and Asset Considerations
While selecting and assessing various populations and assets to include in the Vulnerability Assessment,
the City considered the differences in the population sample pool between datasets and how some
populations and asset categories may appear to refer to the same thing.
Statistics, especially statistics related to population, use the concept of a “sample pool.” In the context of
this Vulnerability Assessment, the sample pool draws from the overall group of people that are being
measured or studied. For example, in a political poll among registered voters, the sample pool only
includes registered voters, since unregistered voters do not fall into this category.
This concept is important because some of the demographics used in the Vulnerability Assessment have
different sample pools. Most of the demographic data come from the US Census Bureau’s American
Community Survey (ACS), and most of these data have a sample pool of either all residents or all
households in the city. However, a few are different, such as:
• Data on persons with limited English proficiency only count people who are at least 14 years old
instead of the total population, since young children generally are not proficient in any language.
• Statistics that only count the noninstitutionalized population (e.g., people not in prisons or long-
term care homes).
This does not affect the outcome of the Vulnerability Assessment, but it creates slight differences in the
number of people counted as part of each population.
Of the 64 populations and assets in the Vulnerability Assessment, a few may appear redundant. For
example, the Vulnerability Assessment looked at both public safety buildings (as a Buildings asset) and at
public safety response (as a Key Community Service asset). To be as comprehensive as possible, the
Vulnerability Assessment looks at physical structures separately from the services or benefits they
provide. In the same way, the Vulnerability Assessment looks at frontline or underserved populations
separately from the homes they live in or the industries where they work.
This is because the effects of climate change on one type of population or asset can be different from the
effects on related populations and assets. For example, if a flood damaged or destroyed a rural road, such
as SR-111, it would have a significant impact on public safety services in and around the city. However,
the loss of SR-111 would do no physical damage to police or fire stations. Similarly, a drought can have a
major effect on water and wastewater services by reducing the amount of water available, but droughts
have little or no physical effect on water and wastewater pipelines or pumps.

Populations
Of the 17 populations evaluated in the vulnerability assessment, 14 were highly or severely vulnerable
(scoring V4 or V5) for at least one hazard type. Populations generally are most vulnerable to wildfire,
extreme heat, and air quality. The most vulnerable populations include households in poverty, immigrants
and refugees, outdoor workers, persons experiencing homelessness, seniors living alone, and
undocumented persons. The list below summarizes the high and severe vulnerabilities, grouping together
populations with similar impacts or adaptive capacity.
Households with financial instability, which are households that may have limited incomes or be cost
burdened (paying at least a third of their gross income on housing costs), are severely or highly vulnerable
to all hazards that will impact Palm Springs. These persons, especially households in poverty, are more
likely to live in homes with less insulation, less structural stability, or lack of air conditioning, increasing
exposure to unsafe living conditions due to mold and mildew damage from flooding, high indoor air
temperatures from extreme heat and warm nights, and poor indoor air quality from air pollution and
severe weather. Households with financial instability may lack the financial means to recover from
property damage or illnesses cause by climate change hazards.
Persons that spend an extended amount of time outdoors, including children and outdoor workers, are
severely vulnerable to air quality, extreme heat, human health hazards, and smoke from wildfires.
Children tend to spend more time outdoors than many adults and may not be aware of the onset of heat-
related illnesses such as heat exhaustion or heat stroke. Reduced air quality from smoke, ozone, or
particulate matter can also decrease the ability of young children to adapt to warmer temperatures over
time. Outdoor workers are directly exposed to extreme heat, human health hazards, and the poor air
quality due to the outdoor nature of their occupations. Outdoor work often involves physically intense
work, which can increase the risk of medical complications. Outdoor work can be halted during hazardous
conditions, such as sandstorms or flooding, creating economic hardships for outdoor workers. This may
also limit the ability of outdoor workers to seek medical attention for heat or air quality related illnesses.
Persons with existing health conditions or limited mobility, such as seniors, seniors living alone, persons
with chronic illnesses, persons with disabilities, and persons without access to lifelines, are highly
vulnerable to air quality, extreme heat, human health hazards, landslides, and wildfire. Extreme heat,
pathogens from human health hazards, and smoke from wildfires can cause cardiovascular and
respiratory illnesses, which may be difficult for many people to recover from, especially those with
compromised immune systems or chronic illnesses. Seniors especially are usually more susceptible to
heat-related illnesses, pathogens, and smoke conditions because they are more likely to have medical
conditions that can worsen with extreme heat and often take medicine that makes it harder for them to
stay cool. These individuals may also have difficulty evacuating during emergencies caused by flooding,
landslides, or wildfires. Power outages can also isolate these persons and potentially cause life-support
systems to fail.
Persons with language barriers and citizenship uncertainty are highly or severely vulnerable to multiple
hazards due to their citizenship, language barriers, or immigration status. Most of these populations may
be hesitant to seek help or may not qualify for financial assistance programs that can help them prepare
and recover from a disaster. People with citizenship or immigration concerns, such as undocumented
immigrants, are severely vulnerable to air quality, extreme heat, human health hazards, and severe
weather, because this population may not live in structures that adequately shelter from these hazards

and they may be required to work in extreme heat or poor air quality conditions. If employers halt work
because of hazardous conditions, undocumented persons may face financial hardship. These individuals
may also live in low-lying areas or in structures that are less resilient to damage, and therefore are highly
vulnerable to severe weather and flooding.
Persons experiencing homelessness lack permanent and often temporary shelters, which can leave them
directly exposed to high temperatures, poor air quality, sandstorms, and smoke from wildfires. These
persons may not have access to cool locations, water, sunscreen, or protective equipment to increase
resiliency to extreme heat and human health hazards. Persons experiencing homelessness are also
severely vulnerable to severe storms and may have a challenging time recovering if high winds and
intense rain events damage or destroy temporary shelters and personal property.
Persons living on single access roads are primarily in the western part of Palm Springs, which is adjacent
to the San Jacinto Mountain range and located in landslide and wildfire hazard areas. These persons are
severely vulnerable to landslides and highly vulnerable to wildfire. Landslides and wildfires can block
single access roadways, preventing persons living on these roadways from evacuating during an
emergency.
Built Systems and Services
The built systems and services include vulnerabilities to infrastructure, buildings, and services that the
City and other organizations provide. The built systems and services are most vulnerable to flooding and
landslides. Of the 38 infrastructure, building, and service assets in the assessment, 21 were highly or
severely vulnerable (scored V4 or V5) for at least one hazard.
Single-access roads have the largest number of high and severe vulnerability scores due to the absence of
alternative routes available. Many single access roadways, such as Palm Canyon Drive, are within or
adjacent to the San Jacinto Mountains, and therefore are severely vulnerable to landslides. Landslides can
make single-access roadways impassable, isolating those who live on these roads and preventing them
from evacuating. Single access roadways, such as Indian Canyon Drive in northern Palm Springs, can also
become impassable due to flooding, sandstorms, and wildfires, which can undermine the foundations or
the materials of these roads.
Homes and residential structures are severely vulnerable to landslides and highly vulnerable to flooding,
severe weather, and wildfire. Homes in western and southern Palm Springs are in high wildfire and
landslide potential areas due to their proximity to the San Jacinto Mountains. These hazards can damage
or destroy homes.
Homes throughout the city are in the 100-year or 500-year floodplains and can be destroyed by large
floods or flash floods. If flooding does not destroy a home, it can leave mold and mildew, making the
structure uninhabitable.
Homes, especially older homes, can also be damaged by high winds, sandstorms, and other severe
weather. According to the American Community Survey 2019 five-year estimates, over half of homes in
Palm Springs were built prior to 1980, with a large portion of homes built between 1960 and 1980. The
Home Energy Assessment rebate program and funding sources such as Energy Savings Assistance
Program, Multi-family Green Initiative, SoCal Gas rebates, and SCE energy-efficiency upgrades can help
low-income residents and homeowners retrofit their homes. Homes can also be hardened against
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 25
flooding and landslides, and defensible space can be created to prevent damage from wildfires. However,
these adaptive options can be expensive and are not always feasible for residents with fixed or limited
incomes.
Air services are highly or severely vulnerable to extreme heat and severe weather because airplanes may
not be able to take off or land during dangerous conditions. During extreme heat events that reach 115oF
to 120oF, aircraft may be unable to generate enough lift during take-off because the air is less dense. This
can ground airplanes and cause delays in air services, sometimes for hours. Dust storms and high winds
create low visibility and dangerous conditions for aircraft. These events can also delay air services hours
or days, depending on the severity. Visitors and residents that use Palm Springs International Airport may
be able to use other airports, but these may not have commercial flights or be much farther away.
Evacuation routes and transportation infrastructure are highly or moderately vulnerable to extreme heat,
flooding, and severe weather. Extreme heat and prolonged periods of high temperatures can crack,
heave, or deform roadway materials, damaging major roads and evacuation routes or making them
difficult to drive on. Evacuation routes, such as I-10 and SR-111, have sections that are within the 100-
year floodplain. Floodwaters can make these major routes impassable and prevent people from
evacuating during an emergency. Windblown sand can cover evacuation routes and make them
impassable so that it is difficult or impossible to evacuate in an emergency. Roadways can be retrofitted
with materials that have higher temperature thresholds, evacuation-designated roadways can be raised
to prevent flooding, and roads can be cleared of debris from severe weather. Though Caltrans may have
funds for increased roadway maintenance, Palm Springs may not have the budget to increase
maintenance on local roadways.
Energy infrastructure and delivery services are highly or severely vulnerable to extreme heat, flooding,
landslides, severe weather, and wildfire. Energy delivery services depend on overhead power lines, power
plants, and underground natural gas pipelines, which are owned and operated by SCE and SoCal Gas and
are susceptible to extreme heat, flooding, high winds, landslides, and wildfire.
Extreme heat can cause power outages due to mechanical failure of electrical equipment, heat damage
to the above-ground infrastructure, and a high demand for electricity due to air conditioning units.
Increased electricity usage for air conditioning during heat waves can overtax electrical transmission lines
and transformers, which may disfunction or fail, causing power outages. Solar and wind energy
production could also decrease due to extreme heat. Solar photovoltaic panels experience a 10 to 25
percent decrease in efficiency when converting solar energy to electric energy in high temperatures.
Severe weather with high wind speeds can make wind turbines lock in place to prevent damage, and
cause transmission lines to sway close to each other, potentially leading to arcing. This can generate
sparks, excessive heat, and damage the lines. In high winds from severe weather, SCE may turn off
electricity in a Public Safety Power Shutoff to prevent sparks, disrupting energy delivery to the city.
Wildfires can damage power lines, natural gas lines, and substations. Landslides can damage both
electrical transmission lines and natural gas pipelines if their foundations are undermined or fail. SCE and
SoCal Gas can retrofit power lines and other equipment to insulate them against extreme heat events and
severe weather and remove diseased or dead trees surrounding the lines and underground utilities to
protect them from falling trees and wildfires.
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 26
Communication infrastructure and services, including phone, cable, and internet, are highly vulnerable to
severe weather that blows dust and soil from the Salton Sea area. This can cause power outages that turn
off communication infrastructure, preventing visitors, businesses, and residents from receiving
emergency notifications and evacuation notices. Communication facilities can be retrofitted to prevent
damage and keep communication capabilities on. However, there may not be many redundancies in the
communication system in the city that can be brought online if others fail.
Transit infrastructure and service are highly vulnerable to extreme heat, flooding, and severe weather.
Extreme heat can disrupt roadways, and fewer people may use public transit because it is harder to wait
for the bus outside in the sun. Many of the SunLine bus routes are also in a flood hazard zone. These
routes could be flooded and become impassable due to floodwaters, preventing residents who depend
on transit from accessing essential goods and services, and commuters from traveling to or from work.
Severe weather can delay or reroute buses due to dust storms and high winds, which can last for hours or
even days. Buses can be rerouted to avoided flooded roadways, and infrastructure can be retrofitted to
resist damage from severe weather. However, those who depend on public transit may not have other
options to get to important destinations while services are not running.
Water and wastewater infrastructure and services are highly vulnerable to landslides, severely vulnerable
to flooding, and highly vulnerable to drought. Landslides can damage or break water and wastewater
pipelines, which could cause water or sewage to leak. Flooding can cause the wastewater treatment plant
to be inundated with wet weather flows due to higher levels of stormwater, preventing the system from
functioning properly. Failure of the wastewater treatment plant could cause sewer collection systems to
back up and potentially overflow raw sewage into streams and water systems. Drought conditions can
stress water agencies that provide water to Palm Springs if supplies from the Colorado River and
groundwater become significantly reduced due to lack of snowmelt into the river or recharge into the
groundwater basins. Water agencies may apply drought rate surcharges and require mandatory
reductions in overall water use. Water and wastewater systems can be retrofitted to prevent damage
from flooding and landslides and ensure continuity of service. However, wastewater cannot be easily
rerouted if the system is damaged or disrupted. Water delivery agencies can also provide water rebate or
retrofit programs to help businesses and residents in the area reduce overall water consumption.
Parks and open space are severely vulnerable to wildfire and highly vulnerable to landslides. The regional
and State parks and open space are in wildfire-prone areas that can be damaged or destroyed by
wildfires, including the Palm Springs Aerial Tramway and visitor centers. Defensible space and vegetation
management in parks and open spaces can protect facilities and city residents, but these actions may not
always be feasible. Parks and open space, especially open space in the San Jacinto Mountains, are in a
high landslide susceptibility area. Landslides can damage trails, signage, and other facilities that support
recreation. Slope stabilization methods can be implemented in open space areas to reduce landslide
potential. However, little can be done to protect open space facilities if a landslide occurs.
Emergency medical response is highly vulnerable to human health hazards, as an increase in vector-borne
and other illnesses may cause the demand to outweigh the capacity of emergency medical response
services. There may be shortages of health care facilities, equipment, pharmaceuticals, and personnel if
health care workers become sick or if supply chains are disrupted. Local and regional medical centers and
providers can strengthen medical supply chains and prepare emergency contingency plans for when
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 27
human health hazards increase in frequency and intensity. However, this may take time and require
extensive coordination with multiple agencies and companies.
Commercial centers along South Palm Canyon and South Indian Canyon Drive, the Smoke Tree Shopping
Center, and the Springs Shopping Center are in flood hazard areas. These buildings can be damaged by
stormwater during floods. Commercial buildings can install green infrastructure and other flood control
infrastructure to divert flood flows, but this can be expensive for small, privately owned businesses.
Homeless shelters and supportive facilities are highly vulnerable to severe weather and can be damaged
by high winds, hail, and sandstorms. The services supported by these buildings may be inadequate or
disrupted if the facilities are damaged. Homeless shelters are typically managed by nonprofit or faith-
based organizations that may not get financial support from local agencies and may not have the funding
for repairs if their facilities are damaged.
Economic Assets
Economic assets include vulnerabilities to economic drivers within the City of Palm Springs. Important
economic sectors are most vulnerable to flooding, extreme heat, air quality, and wildfire. Of the six
economic assets in the assessment, four were highly or severely vulnerable (scored V4 or V5) for at least
one hazard.
State and regional parks are severely vulnerable to wildfire and highly vulnerable to air quality, drought,
extreme heat, and landslides. Palm Springs is home to the Palm Springs Aerial Tramway, which takes
visitors over 5,000 feet up from the Valley Station to the Mountain Station in San Jacinto State Park.
Wildfires can harm State and regional park facilities such as the tramway and roadways, preventing
visitors from accessing these recreation sites. Some State and regional park facilities can use defensible
space and other protective actions, but these options are not always feasible. Regional wildfires can also
create smoky conditions that, when combined with poor air quality from ozone and particulate matter
from the Salton Sea, deter visitors from visiting State and regional parks. Impacts may become chronic
with an increase in poor air quality conditions due to high winds and extreme heat. Extreme heat can
create dangerous conditions for hikers and bicyclists, as people must regularly stay hydrated and not
overexert themselves in hot temperatures. Some of the State and regional parks, such as the Mt. San
Jacinto State Park, are at higher elevations and may not have as severe air quality impacts from the Salton
Sea. An increase in drought conditions could dry out vegetation supporting trails and cause erosion,
reducing the number of trails available to visitors. When heavy rainfall occurs due to severe storms,
destabilized slopes could turn into mudslides or debris flows, damaging park facilities and residential or
commercial areas downslope.
Outdoor recreation is severely vulnerable to poor air quality and extreme heat, and highly vulnerable to
flooding and wildfires. Outdoor recreation can be curtailed by unhealthy air quality conditions resulting
from particulate matter from the Salton Sea or high temperatures. Intense physical exertion from
running, bicycling, and hiking can be dangerous during poor air quality conditions and extreme heat, and
people must stay hydrated to avoid heat and respiratory illnesses. Several parks, trails, and golf courses
are in floodplains or wildfire-prone areas, which could be damaged by flooding or wildfire that burn
supportive vegetation and recreation facilities. Visitors could be deterred from traveling to the city if poor
air quality and extreme heat create unfavorable conditions, especially if water stations are not available
at outdoor recreation sites, and flooding or wildfires damages outdoor recreation facilities. Other
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 28
locations for outdoor activities may have lower temperatures or better air quality, but they would likely
not be in Palm Springs or nearby cities. Recreation sites could be managed for flooding and wildfires;
however, this may not be feasible for all outdoor recreation sites.
Renewable Energy is highly vulnerable to flooding and severe weather. Flooding can damage solar panels
and the foundations of wind turbines at commercial and large scale renewable energy sites, many of
which are in the floodplain of the Whitewater River. Renewable energy workers may be unable to travel
to the facilities until the water recedes. Solar- and wind-power generation facilities can be retrofitted to
prevent damage from floodwaters, and some facilities are outside of the floodplain that could provide
similar services. Solar and wind facilities can also be disrupted by high winds or sandstorms due to severe
weather. Sandstorms can increase erosion to solar panel infrastructure, and high winds can cause wind
turbines to stop working due to safety concerns, harming the industry, the workers, and renewable
energy supply. Some renewable energy sources may not be damaged by severe weather, but solar panels
would require more maintenance after these events. There is little that can be done to retrofit wind
turbines to keep operating during high wind events.
Tourism is highly vulnerable to flooding and human health hazards. Much of the city is in a flood hazard
zone, including roads and recreation facilities that are used by visitors. Flooding can make highways
impassable or damage buildings and facilities that attract visitors, deterring them from traveling to the
city. Several levees around the city protect areas from floodwaters; however, a major flood event may
still damage facilities and deter tourists from traveling to the area. Human health hazards could cause
commercial, retail, and hotel businesses to close, preventing visitors from traveling to the area.
Businesses can take health precautions and provide more advertising to attract visitors to the area, but
some businesses may not be able to remain open if tourism decreases significantly.
Ecosystems and Natural Resources
Ecosystem and natural resources include vulnerabilities to habitats, plants, and wildlife in Palm Springs.
Ecosystems and natural resources are most vulnerable to drought, extreme heat, and wildfire. Of the five
ecosystems and natural resources included in the assessment, four were highly or severely vulnerable
(scored V4 or V5) for at least one hazard.
Juniper woodlands are severely vulnerable to wildfires and highly vulnerable to drought, extreme heat,
and landslides. Wildfires and extreme heat can cause a higher mortality rate among juniper woodlands,
especially with increased frequency. This can shift the ecosystems to a shrub or grassland habitat type
because juniper woodlands have a very long recovery time. Juniper woodlands are also not as tolerant of
drought conditions as scrub or desert ecosystems, and can experience reduced growth, shift in species
composition, and increased occurrence of pests and diseases during prolonged droughts. Due to their
location in mountainous areas of the city, juniper woodlands can also be disturbed by landslides and less
able to recover due to other climate stressors that weaken the ecosystem.
Riparian forests and woodlands are highly vulnerable to drought and extreme heat. Successive drought
years could lead to an earlier, more rapid seasonal drying down of riparian communities, causing a
compositional shift in the community and degraded water quality due to lack of water. Herbaceous
species could die out due to loss of surface water; however, established trees could persist by accessing
groundwater with their deep roots. Groundwater may keep larger trees alive; however, severe drought
could cause the water table to sink below the reach of roots. An increase in extreme heat days and
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 29
average high temperatures could result in higher rates of evapotranspiration, which could also lead to an
earlier, more rapid drying out of riparian communities. Successive extreme heat years could lead to
general shrinking of riparian zones, increasing competition between species that use these areas.
Sonoran Desert scrub is highly vulnerable to wildfire. Wildfires in desert scrub habitats can prevent native
shrub regeneration and kill resprouts or seedlings, especially with shorter fire return intervals. Although
desert scrub habitat can typically regenerate after a fire, shorter fire return intervals can make this more
difficult for the ecosystem.
Desert interior dune is highly vulnerable to flooding, which can cause soil scouring and deposition in
desert interior dune habitats because the soils are unable to store the increase in water, ultimately
harming native species in the dune ecosystem. Desert interior dune ecosystems are slow to recover, and
native species may not be able to adapt to more frequent flooding, especially in the summer months.
IMPLICATIONS FOR THE GENERAL PLAN UPDATE
Equity and Uncertainty
When addressing vulnerability and adaptation through general plan policies and the associated
implementation plan, the Adaptation Planning Guide and General Plan Guidelines recommend
consideration of equity and uncertainty.
Equity means that all people are justly and fairly included in society, and that everyone can participate,
prosper, and achieve their full potential. Equitable climate adaptation planning involves identifying
persons who are most vulnerable to climate change hazards and ensuring that the planning process,
distribution of resources, and efforts to address systematic wrongs are all conducted in an equitable
manner. This vulnerability assessment identifies 17 vulnerable populations and assesses climate change
impacts and the ability of these populations to prepare for, respond to, and recover from climate change
hazards (see list in “Populations and Assets” section).
Uncertainty is the second component to consider when determining how hazardous conditions may
affect Palm Springs. Climate change is driven by the concentration of GHGs in the atmosphere, which is
affected by how our communities use resources and how we regulate those uses through local, state,
federal, and international GHG-reduction goals, regulations, plans, and programs. As more action is taken
to reduce GHG emissions, the less severe the effects of climate change are expected to be. Climate
change models consider the concentrations of atmospheric GHG emissions and the changes in these
levels over time to project future extent or intensity of hazardous events.
Even with extensive modeling, potential impacts are projections of more likely future conditions and are
not certain. Similarly, there is also substantial uncertainty about the future state of technology,
socioeconomic conditions, and other factors. According to recent studies, the best approach to
uncertainty is to prepare and adapt by monitoring how the future evolves and allow for adjustments over
time as new climate data and studies are completed. The State and the City have ample evidence to
support science-based policy and decision-making.
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 30
Opportunities
Palm Springs currently experiences a wide range of climate change hazards that are projected to increase
in frequency and intensity in the future. Though GHG reduction measures in the 2013 City of Palm Springs
Climate Action Plan and 2016 City of Palm Springs Sustainability Master Plan will help reduce the amount
of carbon dioxide in the atmosphere, adaptation strategies will be needed to increase the resilience of
residents and businesses in Palm Springs. The general plan is required to integrate adaptation measures
into the update process that will help the community prepare for, respond to, and recover from climate
change hazards.
• Safety. Due to the recent update of the California Government Code Section 653029(g) with the
approval of SB 379, safety elements are required to address climate adaptation and resilience
strategies. The Safety Element’s goals, policies, and implementation actions can provide
resilience strategies that support reduced impacts and improved adaptive capacity of the
community to climate change-related hazards, along with policies on required hazards such as
flooding, fire, and geologic hazards. Policies in this element can ensure that the health, safety,
and economic concerns of the community are met, even with an increase in frequency and
intensity of climate change hazards. Examples of specific policies or implementation actions could
include:
o Create an extreme heat response plan that includes establishment of community cooling
centers, weatherization of city buildings, and cooling strategies for persons engaged in
outdoor work and persons experiencing homelessness.
o Expand participation of programs and services that provide funding resources for
economically disadvantaged households and businesses to conduct retrofits.
o Coordinate with City and regional transit providers to identify alternate routes and stops
if normal infrastructure is damaged or closed as a result of extreme events.
o Collaborate with SunLine and other senior transit agencies to help in evacuation efforts
of seniors and people without vehicles during emergency events.
o Encourage or incentivize residential and on-site solar systems, especially when paired
with battery storage to provide a resilient energy supply for homes.
o Coordinate with County of Riverside Public Health to ensure emergency and public health
services can meet the needs of the population during extreme heat, poor air quality, and
human health hazard events.
o Provide alerts about potential, developing, and ongoing emergency situations through
extensive early-warning and notification systems that convey information to all residents
in multiple languages and formats to ensure it is widely accessible.
• Circulation. The Circulation Element has policies for wastewater treatment and collection, storm
drainage systems, water supply and distribution systems, electricity, natural gas, and
telecommunications infrastructure. Buildings and utility infrastructure are in the vulnerability
assessment results discussion, and therefore resilience strategies for these systems would be
appropriate to add to the Circulation Element goals, objectives, and policies. Potential objectives
and policies may include funding efforts to underground electricity lines citywide, create
redundances in the communication infrastructure, and provide sustainable backup power
supplies. Strategies can also look at the promotion of water conservation measures, low-impact
development, and green infrastructure that can help convey stormwater and reduce flooding.
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 31
Transportation related strategies can include improving evacuation access, ensuring heat-
resistant materials are used on roadways, and implementation of other transportation-related
resilience features.
• Recreation, Open Space, and Conservation. The Recreation, Open Space, and Conservation
Element promotes recreation opportunities and a variety of parks and open spaces in and
adjacent to the city, which is essential to ensuring that vulnerable populations can adapt to an
increase in frequency and intensity of hazards, such as extreme heat and wildfires. Park and open
space areas can help reduce air pollution, decrease ambient air temperatures, provide shade
during hot days, act as buffers to slow down and absorb stormwater, among other benefits.
Indoor recreation facilities can provide opportunities for recreation when air quality or
temperatures are unhealthy outdoors. This element can include policies and actions that increase
the urban tree canopy to reduce the heat island effect, clean the air, and protect residents and
visitors from hazardous conditions. Another key component for this element is to attract visitors
to the area for outdoor recreation purposes. Adaptation strategies may include increasing natural
or structural shade, installing water stations, and providing signage about extreme heat hazards
at trailheads and outdoor recreation centers. To address the ecosystem vulnerabilities, this
element can also provide implementation actions to preserve and restore woodland and riparian
habitats to ensure these ecosystems maintain their ecosystem services.
The Recreation, Open Space, and Conservation Element also provides goals, objectives, and
policies for public facilities throughout the city, including community centers and libraries. The
Urban Sustainability Network’s “Resilience Hub White Paper” and Resilience Hubs website
(http://resilience-hub.org/) provides a key resilience strategy for public facilities: the integration
of physical and virtual resilience hubs. These can serve as centralized locations for resources
about climate change, opportunities to reduce emissions, and techniques to increase resilience;
as showcases for sustainability, energy efficiency, and low carbon building; and to help residents
obtain essential resources and information during and after a disaster. Examples of specific
implementation actions could include:
o Identify existing facilities to serve as resilience hubs and cooling centers that open during
emergencies or at specific temperature triggers for residents to seek emergency shelter
or refuge from extreme heat days.
o Coordinate with emergency management services to establish backup power, preferably
from renewable energy sources, and water resources at emergency shelters, resilience
hubs, and cooling centers in case of power outages.
Resilience in Other Planning Mechanisms
Resilience should not be limited to the General Plan. Adaptation and resilience rely on a cross-
department, multidisciplinary approach for successful implementation. The City should consider how
adaptation and resilience can also be incorporated into other City plans, codes, projects, and
implementation programs. Addressing climate change hazard events in the General Plan can support
other essential safety documents, such as the City of Palm Springs Local Hazard Mitigation Plan.
Development standards, such as residential building codes for buildings in flood zones, fire safe standards
for buildings in fire hazard severity zones, and development of adequate evacuation routes, can be
integrated into the Palm Springs Municipal Code. Policies that focus on emergency response to hazards
CITY OF PALM SPRINGS SAFETY ELEMENT UPDATE
VULNERABILITY ASSESSMENT REPORT FINAL
April 29, 2022 | Page 32
can be included in an evacuation plan or an emergency operations plan. Adaptation measures that also
reduce GHG emissions can be integrated into the Palm Springs Climate Action Plan or Sustainability
Master Plan and may support an active transportation plan or bicycle master plan. The City and Desert
Community Energy can coordinate incentives for GHG reduction measures such as rebates for battery
storage facilities. Policies related to drought and flooding may be integrated into the Coachella Valley
Water District’s, Desert Water Agency’s, and Mission Springs Water District’s Urban Water Management
Plans and the Palm Springs Storm Drain Master Plan. Furthermore, the Palm Springs Municipal Code and
Capital Improvement Program can help implement the resilience policies developed in the General Plan
through specific projects, development codes, and budgeting.

ADDENDUM TO THE GENERAL PLAN EIR FOR THE GENERAL PLAN UPDATE
CITY OF PALM SPRINGS
1. Addendum to the Certified General Plan EIR
September 2024 Page 3
1. Addendum to the Certified General Plan EIR
1.1 BACKGROUND
The City of Palm Springs is preparing an Addendum to a certified Environmental Impact Report (EIR) as part
of its General Plan Update. In 2007, the City certified the 2007 General Plan EIR SCH #2006071060 (2007
General Plan EIR), which allowed for the certification of the existing General Plan and its associated land use
buildout projections.
The City of Palm Springs initiated a focused General Plan Update in 2019 to amend the Land Use Element
and also update the Circulation Element. The impetus for the limited 2040 General Plan Update (proposed
project) is for consistency with recently adopted revisions to the City’s Planned Development District (PDD)
ordinance. During the time that the City was undertaking the update, new legislation was passed that
necessitated updates to the City's Housing and Safety Elements. This addendum addresses the Land Use,
Circulation and Safety Elements. A separate addendum was prepared for the Housing Element, as it was
updated in a separate but parallel process.
The proposed project would result in minor changes to land use designations, and as such, the proposed project
provides new growth projections for the proposed project’s buildout year of 2040. All future development in
the City would be required to comply with the General Plan Update’s goals, policies, and implementation
actions, as well as the City’s development standards. In addition, any discretionary actions require independent
and project-specific environmental review.
1.2 PURPOSE OF AN EIR ADDENDUM
According to CEQA Guidelines Section 15164(a), an addendum shall be prepared if some changes or additions
to a previously adopted EIR are necessary, but none of the conditions enumerated in CEQA Guidelines
Sections 15162(a)(1) to (3) calling for the preparation of subsequent EIR have occurred. As stated in CEQA
Guidelines Section 15162 (Subsequent EIRs and Negative Declarations):
When an EIR has been certified or negative declaration adopted for a project, no subsequent EIR
shall be prepared for that project unless the lead agency determines, on the basis of substantial
evidence in the light of the whole record, one or more of the following:
(1) Substantial changes are proposed in the project which will require major revisions of the
previous EIR or negative declaration due to the involvement of new significant environmental
effects or a substantial increase in the severity of previously identified significant effects;
(2) Substantial changes occur with respect to the circumstances under which the project is
undertaken which will require major revisions of the previous EIR or negative declaration due
ADDENDUM TO THE GENERAL PLAN EIR FOR THE GENERAL PLAN UPDATE
CITY OF PALM SPRINGS
1. Addendum to the Certified General Plan EIR
Page 4 September 2024
to the involvement of new significant environmental effects or a substantial increase in the
severity of previously identified significant effects; or
(3) New information of substantial importance, which was not known and could not have been
known with the exercise of reasonable diligence at the time the previous EIR was certified as
complete or negative declaration was adopted, shows any of the following:
(a) The project will have one or more significant effects not discussed in the previous EIR or
negative declaration;
(b) Significant effects previously examined will be substantially more severe than shown in
the previous EIR;
(c) Mitigation measures or alternatives previously found not to be feasible would in fact be
feasible and would substantially reduce one or more significant effects of the project, but
the project proponents decline to adopt the mitigation measure or alternative; or
(d) Mitigation measures or alternatives which are considerably different from those analyzed
in the previous EIR would substantially reduce one or more significant effects on the
environment, but the project proponents decline to adopt the mitigation measure or
alternative.
The proposed project would not trigger any of the conditions outlined in CEQA Guidelines Sections
15162(a)(1) to (3) because these changes would not result in new significant environmental effects or a
substantial increase in the severity of previously identified significant effects requiring major revisions to the
2007 General Plan EIR. The following analysis provides the substantial evidence required by CEQA Guidelines
Section 15164(e) to support the finding that a subsequent EIR is not required and an addendum to the General
Plan EIR is the appropriate environmental document to address changes to the project.
As stated in CEQA Guidelines Section 15164 (Addendum to an EIR):
(a) The lead agency or responsible agency shall prepare an addendum to a previously certified
EIR if some changes or additions are necessary but none of the conditions described in
Section 15162 calling for preparation of a subsequent EIR have occurred.
(b) An addendum to an adopted negative declaration may be prepared if only minor technical
changes or additions are necessary or none of the conditions described in Section 15162
calling for the preparation of a subsequent EIR or negative declaration have occurred.
(c) An addendum need not be circulated for public review but can be included in or attached
to the final EIR or adopted negative declaration.
(d) The decision-making body shall consider the addendum with the final EIR or adopted
negative declaration prior to making a decision on the project.

(e) A brief explanation of the decision not to prepare a subsequent EIR pursuant to Section
15162 should be included in an addendum to an EIR, the lead agency's findings on the
project, or elsewhere in the record. The explanation must be supported by substantial
evidence.
A copy of this addendum, and all supporting documentation, may be reviewed or obtained at the City of Palm
Springs Department of Planning Services, 3200 East Tahquitz Canyon Way, Palm Springs, CA 92262.

with mitigation incorporated:
Aesthetics
Biological Resources
Cultural Resources
Geology and Soils
Hydrology and Water Quality
Land Use and Planning

Noise
Population and Housing
1.4 PROJECT DESCRIPTION
Though the impetus for the limited 2040 General Plan Update is for consistency with recently adopted
revisions to the City’s Planned Development District (PDD) ordinance, changes were made to several
elements to address new legislation and revisions made to the General Plan’s Vision and Priorities. The
changes to the Land Use Element were limited in nature and included mapping and policy changes to:
• Reflect the changes prompted by the update to PDD ordinance (remove references in the General
Plan that are no longer applicable);
• Update the mix of preferred uses in the College Park area to reflect contemporary needs of the
community and direction from City Council to allow for more Medium Density Residential and
Mixed Uses;
• Reflect current ownership and existing uses that are not anticipated to change before the horizon year
of the General Plan; and
• Implement the recommendations of the adopted Section 14 Specific Plan
ADDENDUM TO THE GENERAL PLAN EIR FOR THE GENERAL PLAN UPDATE
CITY OF PALM SPRINGS
1. Addendum to the Certified General Plan EIR
Page 6 September 2024
Changes to the Circulation Element include revisions to roadway network classifications and updates to goals
and policies to reflect best practices and areas of concerns raised by stakeholders. Updates to the Safety Element
address new legislation related to floods, wildfire, evacuation constraints, climate-related hazards and resilience
and to integrate the City’s Local Hazard Mitigation Plan (LHMP), Emergency Operations Plan (EOP) and
other recent planning efforts.
CEQA requires the City to evaluate the environmental impacts that could result from implementation of the
proposed project. The proposed project would result in minor changes to the land use designations and provide
new growth projections for the proposed project’s buildout year (2040).
Table 1, Existing Land Use Estimates and 2007 General Plan and General Plan Update Buildout Projections, shows
existing land use estimates, as well as the buildout projections under the 2007 General Plan and proposed
project. As shown, the changes in land use from the 2007 General Plan compared to the proposed General
Plan do not change substantially. Many of the minor changes in acreage reflect more reliable and accurate GIS
parcel data. The most significant change, by percentage, between the 2007 General Plan and Proposed General
Plan is associated with the employment projection for the institutional land use designation in the proposed
project, which now includes plans for institutional uses adopted subsequent to 2007 that were not considered
at the time that the 2007 General Plan was adopted. It should also be noted that development occurring in the
future under the proposed General Plan would occur as market demand requires, and it is unlikely that full
buildout shown in the table would occur.

2. CEQA Analysis
As mentioned above, under CEQA Guideline Section 15164, an addendum to an EIR may be prepared if
only minor technical changes are required or if none of the conditions identified in Guideline Section 15162
are present. In the absence of substantial evidence to support a fair argument that the project changes may
result in significant environmental impacts not previously studied, an addendum to the EIR is appropriate.
The following review proceeds with the requirements of CEQA Guidelines Section 15162 in mind. The
following discussion concludes that the conditions set forth in Section 15162 are present, and that an
addendum is appropriate for the proposed project.
Discussion
The discussion in this addendum confirms that the proposed project has been evaluated for significant impacts
pursuant to CEQA. The discussion is meaningfully different than a determination that a project is “exempt”
from CEQA review, as the proposed project is not exempt. Rather, the determination here is that the potential
impacts of the proposed project were disclosed in a previously certified EIR (i.e., the 2007 General Plan EIR),
and that the EIR provides an adequate analysis of the environmental impacts of the proposed project.
Therefore, the City determined that an addendum rather than an exemption is the appropriate environmental
document.
The following identifies the standards set forth in Section 15162 as they relate to the proposed project. The
text that follows the provisions of the law relates to the proposed project.
Findings
There are no substantial changes in the circumstances or new information that was not known and could not
have been known at the time of the certification of the 2007 General Plan EIR. As a result, and for the reasons
explained in this addendum, the proposed project would not cause any new significant environmental impacts
or substantially increase the severity of significant environmental impacts disclosed in the 2007 General Plan
EIR. Accordingly, this EIR addendum has been prepared.
The following identifies the standards in CEQA Guidelines Section 15162 as they relate to the project.
1. No substantial changes are proposed in the project which would require major revisions of the
EIR due to the involvement of new significant environmental effects or a substantial increase in
the severity of previously identified significant effects.
The City of Palm Springs is required to update its General Plan to ensure compliance with new laws and
regulations, and to account for future growth in the City. While the General Plan includes land use
designations that could lead to development, the proposed update does not change the existing land use
designations or result in the approval of any development project. By state law, all subsequent development
must be consistent with the General Plan Update’s goals and policies and the City’s development standards.
ADDENDUM TO THE GENERAL PLAN EIR FOR THE GENERAL PLAN UPDATE
CITY OF PALM SPRINGS
2. CEQA Analysis
September 2024 Page 9
If a future project requires a discretionary action, a project-specific CEQA analysis would also be required.
For ministerial projects the City’s existing development standards and municipal code will ensure that
physical impacts of the development would be addressed consistent with the General Plan. Environmental
protections such as biological, cultural, and water quality, are addressed through existing laws or permits
that apply to ministerial actions.
The changes included in the proposed project are intended to align with the City’s growth rate. As shown
in Table 1, under existing conditions, the City’s built conditions are less than those projected in the 2007
General Plan. As such, the proposed project includes minimal changes to the growth projections for the
buildout year of 2040. These changes to the growth projections under the proposed project are not
substantially different from the buildout projections in the 2007 General Plan. As shown in Table 1, the
changes to the amount of development in the City from the existing General Plan and the proposed
General Plan would be minimal. For example, the number of residential units under the proposed General
Plan would represent a less than one percent increase compared to the existing General Plan and building
square footage allowed would increase by only approximately 2.5 percent. Given the rate of growth from
the 2007 General Plan compared to existing conditions, it is unlikely that the 2040 General Plan would be
built out to either the existing or proposed General Plan. Therefore, as the proposed project would not
result in substantial changes compared to the 2007 General Plan EIR, nor would it result in any physical
change to the environment, there are no new environmental impacts, nor would there be an increase in the
severity of any previously identified environmental impacts.
2. There is no new information of substantial importance, which was not known and could not have
been known with the exercise of reasonable diligence at the time the previous EIR was certified
as complete demonstrating that the project will have one or more significant effects not discussed
in the previous EIR.
The mitigation measures identified in the 2007 General Plan EIR would continue to apply to all
development in the City and would have the same mitigating effect as disclosed in the 2007 General Plan
EIR. There is no new information that was not known and could not have been known at the time the
2007 General Plan EIR was certified demonstrating that the proposed project would have one or more
significant effects not discussed in the previous EIR. Moreover, given the rate of growth from the 2007
General Plan, compared to existing conditions, it is unlikely that the proposed project would be built out
to its maximum projections by 2040. Therefore, as the proposed project would not result in substantial
changes compared to the 2007 General Plan EIR, nor would it result in any physical change to the
environment, there are no new environmental impacts, nor would there be one or more significant impacts
not previously discussed in the 2007 General Plan EIR.
3. There is no new information of substantial importance, which was not known and could not have
been known with the exercise of reasonable diligence at the time the previous EIR was certified
as complete demonstrating that significant effects previously examined will be substantially more
severe than shown in the previous EIR.

2. CEQA Analysis
Page 10 September 2024
The proposed project would have the same significant impacts as those disclosed in the 2007 General Plan
EIR, as the changes under the proposed project are minimal. The mitigation measures in the 2007 General
Plan EIR to reduce physical environmental effects would apply to all new development under the proposed
project. There is no new information that would demonstrate that significant effects examined would be
substantially more severe than shown in the certified 2007 General Plan EIR. Moreover, given the rate of
growth from the 2007 General Plan, compared to existing conditions, it is unlikely that the proposed project
would be built out to its maximum projections by 2040. Therefore, as the proposed project would not
result in substantial changes compared to the 2007 General Plan EIR, nor would it result in any physical
change to the environment, there are no new environmental impacts, nor would there be an increase in the
severity of any previously identified environmental impacts.
4. There is no new information of substantial importance, which was not known and could not have
been known with the exercise of reasonable diligence at the time the previous EIR was certified
as complete demonstrating that mitigation measures or alternatives previously found not to be
feasible would in fact be feasible and would substantially reduce one or more significant effects
of the project, but the project proponents decline to adopt the mitigation measure or alternative.
The mitigation measures identified in the 2007 General Plan EIR would continue to apply to all
development in the City and would have the same mitigating effect as disclosed in the 2007 General Plan
EIR. There is no new information that was not known and could not have been known at the time the
2007 General Plan EIR was certified demonstrating that mitigation measures or alternatives previously
found not to be feasible would now be feasible. Compared to the 2007 General Plan EIR, the changes
under the proposed project are not substantial. Moreover, given the rate of growth from the 2007 General
Plan, compared to existing conditions, it is unlikely that the proposed project would be built out to its
maximum projections by 2040. Therefore, as the proposed project would not result in substantial changes
compared to the 2007 General Plan EIR, nor would it result in any physical change to the environment,
there are no new environmental impacts, nor would there be substantial changes to the conclusions of the
2007 General Plan EIR or a requirement for new mitigation measures.
5. There is no new information of substantial importance, which was not known and could not have
been known with the exercise of reasonable diligence at the time the previous EIR was certified
as complete demonstrating that mitigation measures or alternatives which are considerably
different from those analyzed in the previous EIR would substantially reduce one or more
significant effects on the environment, but the project proponents decline to adopt the mitigation
measure or alternative.
Compared to the 2007 General Plan EIR, the changes under the proposed project are minimal and not
substantial. Given the rate of growth from the 2007 General Plan, compared to existing conditions, it is
unlikely that the proposed project would be built out to its maximum projections by the General Plan’s
horizon year. There are no new mitigation measures or alternatives to the proposed project that would be
required.

Title: Boulders and Crescendo projects to become open space
Write your message here:
I’m writing to inquire about the status of the land that the city acquired in the settlement
with Grit Development back in 2019. I am not writing in any official capacity or representing
the Little Tuscany Neighborhood Organization. As we’ve discussed before, I am greatly
concerned that these two parcels, known as Boulders and Crescendo, have not yet had
their ’status’ changed to reflect that they are to remain open space. That is unless I’ve
missed it! With the coming election in November, we are almost certainly going to see two
new members join the council, and with each passing year, the memory of how this land
was acquired, and what had transpired in the decades before that, is becoming lost. A
previous council voiced sentiments (that led many of us in the neighborhood heard and
relied upon) to indicate that it was their intention to acquire that land in the settlement with
Grit Development and then to ultimately change the land use designation to ensure that it
would remain undeveloped. I fear that a future council in challenging financial times may
see these parcels as a source of cash and sell to a developer. If a developer were to build
out these parcels to the limit, we’d see more than 100 homes built… the very thing that I
and many others fought for literally 20 years. Perhaps the best thing would be to transfer
ownership of these parcels to a conservancy group such as Friends of the Desert
Mountains. Please let me know if there’s anything I can do.

Subject: Re: General Plan Update
David,
Thank you. Here are my comments for the record.
General Plan Classification of the Roadway
The classification of W. Racquet Club Road should be changed to a local roadway
classification. In the 2007 General Plan it was identified as a collector as there were different
plans in place at the time that have substantially changed since 2007. In addition to changing
the classification this may offer several residents the ability to remove dedications that were
required for a much larger roadway. According to the General Plan a local roadway is:
Local and Private Streets. Primarily provide access to individual parcels
of land. Minimum right-of-way is 50 feet for public local streets. Typical
street widths for local public streets and private streets are 36 feet as
shown on Figure 4-2. In Estate, Very Low, and Low Density Residential
neighborhoods, local public street widths may be reduced to 28 feet (curb
face to curb face) provided that (1) additional off-street parking is
provided as determined by the City Engineer, the Fire Chief and Director
of Planning, (2) rolled or wedge curb is provided such that vehicles may
park partially out of the traveled way, and (3) pedestrian pathways or
sidewalks, if located along the street, separated from the curb by a
minimum five-foot parkway, are provided.

Subject:General Plan Amendment Suggestion
NOTICE: This message originated outside of The City of Palm Springs ‐‐ DO NOT CLICK on links or open attachments unless you are

David: Please forward this GP request re FARs to the Commission and an advisory committee if that exists. There is no
way to make use of the high rise ordinance with the FARs currently being enforced. If you can show me how, I’m all ears.
I am CCing Margaret Park as I promised her as a heads‐up.
To the Palm Springs Planning Commission
General Plan Update Request/Suggestion: Amend the language in the Land Use sections concerning Floor Area Ratios
(FARs) to indicate that the FARs are an overall community goal and that individual zones would have an appropriate FAR
that supports the height and bulk standards for each zone while maintaining the now established Overall Community
FAR maximum goals.
Background: The 2007 City of Palm Springs General Plan update included the statistic that the aggregate FAR produced
to date in all industrial zones was 0.23 (e.g. a 2,300 s.f building on a 10,000 s.f. site). Essentially that represents the
average Floor Area need over the years. The Development Standards for Industrial zoning that produced that FAR have
remained static as to Building Coverage, Building height, Setbacks and Parking for 60+ years. There is no discussion in
the 2007 GP (or the proposed Land Use GP text ) that would indicate that Commercial and Industrial developments are
too intense and should be reduced. One might have expected some discussion that mid‐rise and even high‐rise
developments would no longer be allowed.
The 2007 GP added Floor Area Ratios (FARs) as a metric including commercial FARs at 0.35 and industrial FARs at 0.50
with zero discussion of any community concerns about building height or bulk. Recently, the City has asserted that those
FARs are now being imposed on all new projects albeit never having been adopted by Ordinance. Staff rationale
suddenly arose in 2021 due to the need to find any new proposed development as being “consistent with the General
Plan” and the 2007 GP language dealing with FARs that were consistent in the OVERALL with long standing Commercial
and Industrial development standards that occasional encouraged more compact development patterns (also
encouraged by the General Plan)
As it turns out, the FAR usage in the GP was a means to generate build out numbers for use in the traffic study. The city
has had multiple ZO updates since 2007, including the creation of new Industrial zones without any insertion of an FAR
metric. Had the FAR metric been designed to be adopted as law, there should have been some discussion about the
conflicts within the ZO concerning mid and high rise buildings which would be prohibited with the proposed FARs in
commercial and industrial zones.
The FARs both for Commercial (0.35) and Industrial (0.50) have significantly reduced the potential development
potential compared to non‐controversial, existing development standards including building coverage, height and bulk,
and parking. The City’s existing, long standing Industrial, commercial and High Density Residential ZO standards
allowance of 30' to 100’ have no chance with the imposition of 0.35/0.50 FAR mandate. Currently most industrial
standards in the ZO outline 60 percent building coverage and 30’ building heights (by right)and calculate to an effective
2
FAR of 1.2 by right and up to an FAR of perhaps 4.0 under High Rise provisions. BTW, even though the potential project
specific FARs would occasionally be significantly higher than the FARs in the GP, the actual aggregated land use numbers
with the existing development standards are well under the target allowance. Keep the FARs as the overall aggregate
output but expand the GP discussion to accommodate occasional, more intensive developments.
If everyone really wants to eliminate buildings over 30’, then the ZO should eliminate any potential for added height.
Again, Is that anyone’s goal?
I did a bit of research and found that Monterey Park used a spread of 12 different FARs in their GP ranging from 0.60 to
4.0. There were 4 Commercial (0.65 ‐ 1.5), 4 mixed use (1.5 to 2.5), 2 Corporate Center (2.0 to 4.0), 2 Innovation
Technology (0.60 to 0.65) and ability to increase with a CUP. While their numbers might not apply here, their ranges
actually compute fairly well. I did not see in the Monterey Park example whether they used the FARs as traffic predictors
like the 2007 traffic used them.
I think the City would invite input from the Tribe on the issue of insuring full use of commercial and industrial lands
consistent with the long established Zoning Ordinance development standards dating to 1965 and agreed on in 1977
while refining the GP language to embrace FAR ranges with the GP FARs to be based on the aggregate Community FAR
goal.
That 2007 GP done by the Planning Center included the use of FARs as a predictor of traffic generation number
and also added an FAR to the descriptions of several land use types.
There was no discussion of any issues with the then current commercial or industrial development standards.
The actual FAR of the built Industrial base in 2007 was shown as 0.23 while the estimated future FAR was set at
0.50 leaving the possibility of expanded development.
There is no record of any concerns about the building intensity of the existing Industrial base at that time and no
action plans to reset development standards considering that the existing standards are totally out of whack
with the 0.50 FAR set in the GP Industrial text.
Imposition of a One‐Size Fits All FAR, precludes customizing to meet various conditions or circumstances. My
recent experience with an all indoor Public Storage use would suggest that dead storage could result in a higher
FAR but a significant reduction in traffic while meeting the M‐1 Building Height and Coverage standards.
The ability to build up to 60 (or 100 feet in height on various Tribal properties) is essentially voided by imposing
the existing FAR basis in the current GP
The current planning staff and city attorney have decided to impose the GP FAR on every project, even those by
old Right of Zone and they will probably batch a ZO update after the upcoming GP update. They are doing so
despite there being no evidence that the current ZO was out of whack with the industrial goal of 0.50 or
commercial goal of 0.35.
The FARs for Commercial (0.35) and Industrial (0.50) conflict with long standing Zoning Ordinance Development
Standards and effectively disallow 2+, multi‐story development and full use of density built in to the Zoning
Ordinance.
With a high rise application (CUP), an FAR of 4.0 or higher could be needed to match current ZO standards,
either commercial or industrial.
Higher intensity use standards have long been in place since the mid 1960s, and have not changed through
several GP iterations 1973, 1993, and 2007. Why dump that mid‐/high rise capability at this point?

Re: Boulders and Crescendo- land use element changes to general plan
Dear Mayor Holstege and City Council members:
Open space is critical to our quality of life, combating climate change and supporting a thriving ecosystem. Scientists and
environmentalists worldwide are encouraging communities to take part in what is known as the 30 by 30 campaign. This is
an effort to secure 30 percent of open space by the year 2030. It has been stated that this must begin on the local level,
such as in Palm Springs.
Boulders and Crescendo were received by the City of Palm Springs in a settlement with Wessman properties (now called
Grit Development). The community was told that these two properties would be set aside as open space for residents and
visitors to Palm Springs as well as to protect wildlife habitat.
Our coalition had a biological assessment conducted on both properties (see attached) which revealed a tremendous
diversity of both plants and animals on both parcels. In fact, on Boulders, 36 different plant species were observed, 20
different animal species and 14 different occurrences of cryptobiotic crust were observed. On Crescendo, 27 different
species of plants were observed, 11 different animal species and six different occurrences of cryptobiotic crusts were
observed to inhabit the area or rely on it for migratory purposes.
The certified CA Naturalist who completed the biological assessment stated, "It is my recommendation that both Boulders
and Crescendo remain undeveloped and be protected as open space for their outstanding biologic and scenic value.
These kinds of boundary parcels are essential for maintaining ecosystem health along the “Wildland Urban Interface”,
where natural and human communities meet, and in maintaining the
character and attraction of the Coachella Valley desert."
We, the undersigned, are asking the City of Palm Springs either to donate these properties to a land trust for their
stewardship or during the land use update to the general plan this fall, the designation be changed to open space. Doing
so would protect these areas from future development or sale to a developer for that purpose and support the effort to
protect open space. Thank you for your time.

Biological Site Assessment: Boulders and
Crescendo Properties
Palm Springs, CA
Background
On March 18th, 2021, I visited two properties in Palm Springs, CA, referred to as “Boulders” and “Crescendo”,
to complete an initial site assessment and determine the biological habitat value of each site.
Both sites are located at the base of the Chino Cone, an alluvial fan emanating from one of the most significant
drainages of the San Jacinto Mountains. The primary plant community for the sites is Creosote Bush Scrub.
Boulders is located approximately 0.5 miles west of North Palm Canyon Drive, and is abutted by West Chino
Canyon Road to the south, and two Desert Water Agency storage tank facilities to the east and west. The site
consists of approximately 45 subdivided parcels owned by the City of Palm Springs, and is currently
undeveloped open space. It is surrounded on three sides by residential neighborhoods.
Crescendo is located approximately 0.2 miles southwest of North Palm Canyon Drive, and is abutted by
Tramway Road to the northwest and West Racquet Club drive to the south. The site consists of a single parcel
owned by the City of Palm Springs, and is currently undeveloped open space. It is bordered on two sides by
residential neighborhoods.
I visited Boulders in the morning, beginning at 10:00 AM, and spent approximately 2.5 hours completing my
survey, followed by Crescendo, where I spent approximately 1 hour, leaving the site at 1:30 PM. For both sites,
I surveyed the properties by walking around the perimeter, noting biologically important features and signs of
disturbance, and recording the plant and animal species I observed. I also walked the nearby “Desert Palisades
Trail”, as a comparison to the sites in question.
Biological Assessment: Boulders
Plant Life
I observed the following plant species at the Boulders site:
Common Name Scientific Name
white bursage Ambrosia dumosa
cheesebush Ambrosia salsola
fourwing saltbush Atriplex canescens
desert broom Baccharis sarothroides
sweetbush Bebbia juncea

honey mesquite Prosopis glandulosa
Schott's indigo bush Psorothamnus schottii
catclaw acacia Senegalia greggii
cape ricegrass* Stipellula capensis
athel tamarisk* Tamarix aphylla
American threefold Trixis californica
Species Count: 36
* Plants marked with asterisk are not native to the Coachella Valley
Plants highlighted in green had at least one individual observed with flowers
Annual rainfall in the area was well below normal levels as of the date of the survey, and few annual species
were observed. During ideal conditions, spring annual plants can account for as much as 50%, or more, of
plant diversity in desert ecosystems, and it can be assumed that the actual number of plant species occurring
on site is much greater than observed.
Animal Life
I observed the following animal species at the Boulders site:
Common Name Scientific Name Type
Cooper's Hawk Accipiter cooperii Bird
Verdin Auriparus flaviceps Bird
Costa's Hummingbird Calypte costae Bird
Northern Flicker Colaptes auratus Bird
Common Raven Corvus corax Bird
American Kestrel Falco sparverius Bird
House Finch Haemorhous mexicanus Bird
Northern Mockingbird Mimus polyglottos Bird
Phainopepla Phainopepla nitens Bird
Say's Phoebe Sayornis saya Bird
Mourning Dove Zenaida macroura Bird
Common Name Scientific Name Type
Western Honey Bee* Apis mellifera Insect
Creosote Gall Midge Asphondylia auripila Insect
Gray Hairstreak Strymon melinus Insect
Black Harvester Ant Veromessor pergandei Insect
Coyote Canis latrans Mammal
California Ground Squirrel Otospermophilus beecheyi Mammal
Desert Cottontail Sylvilagus audubonii Mammal
Western Whiptail Aspidoscelis tigris Reptile
Western Side-blotched Lizard Uta stansburiana elegans Reptile
Species Count: 20
* Animals marked with asterisk are not native to the Coachella Valley
Animals highlighted in yellow were observed via sign only (scat, tracks, etc.)
Several animal species were observed but not identified to species, including a mating pair of birds of prey,
various perching birds, and invertebrates (insects and spiders). Additionally, the Coachella Valley is an
important breeding area and stopover for migratory birds that only occur here seasonally. The dry conditions
may also have limited the amount of invertebrate activity, and the potential to see some of the larger
herbivorous reptiles known to occur nearby, such as the common chuckwalla and desert iguana. Due to these
factors, it can be assumed that the actual number of animal species occurring on site is greater than observed.
Other Lifeforms: Cryptobiotic Crusts
Cryptobiotic crusts - a community of microscopic organisms consisting of cyanobacteria (blue-green algae),
lichens, mosses, green algae, fungi, and bacteria - are an important part of desert ecosystems, and can be
used as an indicator of the level of disturbance of desert soils.
I documented 14 different occurrences of cryptobiotic crust spread throughout the site, indicating a low
overall level of disturbance. Crusts were found both in the shelter of boulder piles, and in the interspace
between plants, indicating a beneficial diversity of microorganisms.
Signs of Disturbance
Several signs of disturbance were observed. There is a relatively small amount of street trash (broken glass,
discarded bottles), mostly distributed around the perimeter of the site, and two discarded tires near the
southern edge of the property.
Several lengths of steel 6-inch pipe run across the surface of the site, varying in length and quantity. All pipes
visible on the surface appear to be disused. A series of steel posts (approximately 6) runs east-west near the
southern edge of the property, and appear to have been part of a utility line at some point. A series of
temporary wooden posts (approximately 12) runs east-west near the northern edge of the property. All of the
wooden posts are lying down on the ground, and their original purpose was not apparent.
At least two human-created unofficial paths across the site were noted, marked with a combination of rock
cairns and red spray paint. Neither path appears to receive a high level of use.
Several species of invasive plant were observed, including a single small tamarisk tree near the northeast
corner of the site, and a relatively small amount of Saharan mustard. Fountain grass occurrence is generally
low, but reaches higher concentration near the western border with the Desert Water Agency property. The
dried out remains of invasive annual grasses were widespread on the site, although only a small number of
fresh individuals were observed, all cape ricegrass.
Discussion
Overall, I observed a high level of diversity of plants and animals, and a relatively low level of disturbance,
especially considering the proximity of the site to existing developed neighborhoods.
Both the number and composition of species indicate a well-structured ecosystem with a complete food web,
including a variety of common (creosote, brittlebush) and less common perennial plants (threefold, rock
hibiscus, hedgehog cactus), insect life, songbirds and small mammals, and predatory animals (Cooper’s hawk,
kestrel, coyote).
The prevalence of cryptobiotic crusts on the site particularly indicate an intact desert community that is
increasingly rare to find in the Coachella Valley. Cryptobiotic crusts can take decades or centuries to develop.
Many desert plants depend on symbiotic soil relationships with mature cryptobiotic crusts to survive.
Therefore, these crusts contribute to overall ecosystem health and biodiversity.
Biological Assessment: Crescendo
Plant Life
I observed the following plant species at the Crescendo site:
Common Name Scientific Name
white bursage Ambrosia dumosa
cheesebush Ambrosia salsola
fourwing saltbush Atriplex canescens
sweetbush Bebbia juncea
Saharan mustard* Brassica tournefortii
fountain grass* Cenchrus setaceus
browneyes Chylismia claviformis
desert lavender Condea emoryi
silver cholla Cylindropuntia echinocarpa
brittlebush Encelia farinosa
Common Name Scientific Name
California primrose Eulobus californicus
smallseed sandmat Euphorbia polycarpa
California barrel cactus Ferocactus cylindraceus
hairy milkweed Funastrum hirtellum
narrow-leaved cryptantha Johnstonella angustifolia
white ratany Krameria bicolor
creosote bush Larrea tridentata
Wishbone bush Mirabilis laevis
Parry's lip fern Myriopteris parryi
beavertail cactus Opuntia basilaris
Mexican palo verde* Parkinsonia aculeata
blue palo verde Parkinsonia florida
dyebush Psorothamnus emoryi
Schott's Indigo Bush Psorothamnus schottii
cape ricegrass* Stipellula capensis
athel tamarisk* Tamarix aphylla
fan-leaved tiquilia Tiquilia plicata
Species Count: 27
* Plants marked with asterisk are not native to the Coachella Valley
Plants highlighted in green had at least one individual observed with flowers
As with the Boulders location (see above), it can be assumed that the actual number of plant species occurring
on site is much greater than observed, when accounting for spring annuals.
Animal Life
I observed the following animal species at the Crescendo site:
Common Name Scientific Name Type
verdin Auriparus flaviceps Bird
Costa's hummingbird Calypte costae Bird
common raven Corvus corax Bird
Greater Roadrunner Geococcyx californianus Bird
house finch Haemorhous mexicanus Bird
northern mockingbird Mimus polyglottos Bird
mourning dove Zenaida macroura Bird
white-tailed antelope squirrel Ammospermophilus leucurus Mammal
California ground squirrel Otospermophilus beecheyi Mammal
desert cottontail Sylvilagus audubonii Mammal
western side-blotched lizard Uta stansburiana elegans Reptile
Species Count: 11
Animals highlighted in yellow were observed via sign only (scat, tracks, etc.)
As with the Boulders location (see above), it can be assumed that the actual number of animal species
occurring on site is much greater than observed.
Additionally, it was mid-day by the time I reached the Crescendo site and the air temperature was noticeably
warmer, so it was not surprising to see a reduction in animal activity at this site compared to Boulders.
Other Lifeforms: Cryptobiotic Crusts
I observed relatively fewer cryptobiotic crust sites at the Crescendo location (6), possibly due to the higher
level of disturbance (see below). However, the variety of sites indicated a similar level of diversity, and in fact
included at least one location with ferns (Parry’s lip fern), which were not present at the Boulders location.
Signs of Disturbance
Relative to Boulders, the Crescendo site was more highly disturbed. I observed a similar level of street trash,
as well as at least one instance of more significant dumping (furniture, construction debris) near the southeast
corner of the property, and several larger pieces of trash scattered around (folding chair, BBQ).
There is evidence of at least one person establishing a shelter (shade, bedding, chairs, etc) near the western
boundary of the property. It wasn’t clear if the shelter was currently in use at the time of the survey. There is
at least one medium-use human created path running from the northeast to the western boundary (and
beyond)
A large disused steel pipe runs along much of the southeast boundary of the property, and rock and soil has
been pushed back onto the property along the right-of-way at the southern boundary.
A similar combination of non-native and invasive species occurs on the site. The occurrence of fresh Saharan
mustard and cape ricegrass was particularly high near road margins bordering the property to the northwest
and south.
Much of the site shows clear signs of fire damage, and examination of historical satellite imagery indicates
that a fire did occur on most of the eastern portion of the property approximately 3 years ago, sometime
between August of 2018 and July of 2019. The fire footprint covers approximately 30 acres, and appears to
have been extremely low intensity. A small number of shrubs appear to have been completely burned (these
may already have been dead before the fire, and more susceptible to combustion), and some of the existing
shrubs show fire damage (wilting), especially creosote bushes in the southeast corner of the site. Overall, the
fire does not seem to have done significant damage to the property.
Discussion
While I observed somewhat less biological diversity than at Boulders, the Crescendo property remains a well
structured and intact biological community, with plants and animals representing a complete food web, from
annual wildflowers (cryptantha), to predatory animals (roadrunners).
The wildlife observed, and the presence of cryptobiotic crusts on site, make Crescendo a highly visible
example of intact and mature desert creosote bush scrub. The property is immediately adjacent to Tramway
Road, where tens of thousands of visitors pass by each year on their way to the Palm Springs Aerial Tramway,
and within sight of North Palm Canyon Drive and the Palm Springs Visitor Center, one of the main entry points
into the Coachella Valley. The property currently serves as part of the visual backdrop for a “Desert X” art
installation nearby.
Closing Recommendations
It is my recommendation that both Boulders and Crescendo remain undeveloped and be protected as open
space for their outstanding biologic and scenic value. These kinds of boundary parcels are essential for
maintaining ecosystem health along the “Wildland Urban Interface”, where natural and human communities
meet, and in maintaining the character and attraction of the Coachella Valley desert.
In addition to protecting the properties themselves, consider the following actions:
● Utilize community resources (CVAG Homelessness Committee, etc.) to ensure that any persons
currently living on the Crescendo property are able to find permanent shelter.
● Work with surrounding neighborhoods and volunteer groups (Oswit Land Trust, etc.) to clean up
existing street trash and dumping. I estimate approximately one volunteer event (4 hours, 20-30
people) would be sufficient at each site.
● Examine costs and benefits (scrap value?) of removal of abandoned infrastructure (pipes). Remove if
feasible.
● Remove existing invasive species via volunteer events (fountain grass, Saharan mustard), and work
with the Low Desert Weed Management Area to examine methods for annual grass treatment.
● Work with existing neighborhood councils and neighborhood watch groups to report dumping and
other negative activities on the properties.
● Continue biological surveys at both sites, utilizing community science platforms like iNaturalist and
eBird and engage local residents to observe changes over time.
● Work with local neighborhoods to protect and enhance the habitat value of the sites. Ensure adequate
and well maintained covered trash cans to help maintain raven populations at a sustainable level,
avoid trimming trees and palms during spring nesting season, and keep pet cats indoors.
● Examine costs and benefits of recreational opportunities and connections with nearby trails and
attractions (North Lykken Trail, Desert Palisades Trail, Tramway Road, Palm Springs Visitor Center).
Protecting these parcels, and others like them, will help to build resilience and long-term sustainability in the
face of an uncertain climate future.

Dear Members of the Palm Springs City Council,
At one of the recent City Council Meetings, residents were encouraged to make suggestions as you work on our new
General Plan to help improve the city. I have such a suggestion.
There exists a long strip of land along the south side of E. Palm Canyon Drive/Hwy 111. This piece of land, approximately
one block long, has tall palm trees and NOTHING ELSE BUT DIRT AND WEEDS! This strip of dirt and weeds runs from
the exit out of the Smoke Tree Mall (Ralphs and Ace mall) driving East up to the end of this strip of land at Smoke Tree
Lane. Other cities one passes through on the Hwy 111 have well groomed to lavish landscaping depending on the city‐‐
but all are better maintained than ours. This is the impression one has when entering Palm Springs and when leaving‐‐‐
most of the rest of the vegetation on E. Palm Canyon Drive is fine , BUT THIS STRIP OF DIRT IS UNSIGHTLY AND HAS BEEN
LIKE THIS FOR SEVERAL YEARS.
i WOULD ASK THAT YOU AUTHORIZE SOME CRUSHED ROCK TO AT LEAST COVER THE DIRT AND WEEDS. AN EVEN
BETTER FIX WOULD BE TO INSTALL SOME IRRIGATION AND ADD A FEW PLANTINGS‐‐‐anything please but the dirt and
weeds!!! Tourists see this as they stay in surrounding hotels, and as they shop at Ralphs and Ace while in town. It is
truly an eyesore and Palm Springs is too lovely and elegant a city to have a piece of ignored and unsightly strip of land
like this existing amid other plantings and grass before and after this piece of land. I urge you to please take a small
amount of funds to repair this site. Thank you for your care and your time.

Mayor and members of the Council, Joan Taylor here, representing Sierra
Club, speaking to General Plan issues, item 5C.
Regarding the I-10 site near Whitewater under consideration, it appears
partially within a Conservation Area under the Coachella Valley Multiple
Species HCP, and it is inappropriate and unwarranted to create an island of
potential intense development in an area that would otherwise be Open
Space Desert. Vastly changing the General Plan Land Use designation in
this manner for a single site in the abstract may be in violation of CEQA, if
not General Plan case law.
Also, Sierra Club supports retaining the majority of the abandoned Bel Air
golf course in natural open space, as part of the connective tissue of
washes that preserve habitat corridors and multiple use trail amenities and
attractive open space relief for residents and tourists enjoying unique
amenities the City can offer.
I’m not sure how narrow the scope of item 5C is, but Sierra Club strongly
requests the City change the Land Use Des and Zoning of certain
mountainous sites currently designated “Special Policy” areas. Most
importantly the "Special Policy" portion of Palm Hills should be designated
Open Space Mountain, 1du/40 ac — to be consistent w/ other City
mountainous area policies and the voters' express wishes for preservation
of the site, as demonstrated by a resounding referendum of the erstwhile
Palm Hills project.
Also, the former Shadowrock site has been acquired for preservation
should be designated as Conservation, no dwelling units.
Taking my Sierra Club hat off and speaking as a long-time resident of Palm
Springs, I’d like to add that such intense development at the Whitewater
site would be an unfortunate entry to the City as well, especially when there
are better sites in already industrialized areas to the east and west for such
intense uses.
That’s it. Thank you.

Re: Discussion of Draft 2021-2029 Housing Element, Draft Land Use Plan and Proposed Buildout
Honorable Mayor and Members of the City Council:
I am writing on behalf of the Sierra Club to address a question that arose
during the workshop on July 22, 2021 regarding the ability of the City
Council to amend the General Plan in a manner that lowers the allowable
density within the Palm Hills Special Policy Area.
The current General Plan regulations for the Palm Hills Special Policy Area
allow for potential “residential and resort development at a maximum of 1
dwelling unit/hotel unit per acre, not to exceed a total of 1,200 units”,
subject to preparation of a Specific Plan. (General Plan, Page 2-8.) A
suggestion was made that the Special Policy Area be redesignated as Open
Space Mountain (“OS Mountain”), which allows 1 dwelling unit per 40 acres.
In response, I understand the City Attorney stated that the change would
result in a “taking” because it would deny development rights. The Sierra
Club urges the City Council to not accept this opinion as the end of the
story.
There is no state or federal rule that a reduction in density is an automatic,
or “per se,” taking of property rights. To the contrary, a per se taking only
occurs if a regulation denies all economically beneficial or productive use
of land. (Lucas v South Carolina Coastal Council (1992) 505 US 1003, 1020.)
A reduction of density consistent with other adjacent hillside lands within
the City certainly would not qualify as a per se taking. Of course, a
regulation can still result in a taking if a court finds that it goes too far.
When no per se taking exists, courts examine a number of factors to
determine if the regulation “goes too far” such that a taking has occurred.
Factors considered include the economic impact of the regulation on the
claimant, the extent to which the regulation interferes with distinct
investment-backed expectations, and the character of the governmental
action. (See Penn Cent. Transp. Co. v New York City (1978) 438 US 104, 123
and Kavanau v Santa Monica Rent Control Bd. (1997) 16 C4th 761, 775.)

The analysis is complicated and varies with each case. But in the end, if a
substantial use of the property remains, no taking will be found. (See Bridge Aina
Le’a, LLC v. Land Use Commission (9th Cir. 2020), 950 F.3d 610 [applying Penn
Central factors, reclassification of land from urban to agricultural did not result in
a regulatory taking.]
Sierra Club appreciates that the laws governing regulatory takings are extraordinarily
complex and that each regulation must be evaluated in light of the unique property
rights involved. However, the Sierra Club urges the Council to not accept any opinion
that redesignating the Special Policy areas of Palm Hills to OS Mountain would result
in a per se taking. To the contrary, the Sierra Club is confident that a thorough
analysis of the proposal would result in a finding that it would simply place the
Special Policy area on equal footing with surrounding mountainous properties already
designated OS Mountain. The City’s designation of those properties as OS Mountain
did not result in a finding of a “per se” or other regulatory taking because the
properties retain substantial economic value. If follows that a redesignation of the
Special Policy area for Palm Hills would also not result in a taking.

Subject: URGENT: Palm Hills Land Use Designation to Open Space Mountain
NOTICE: This message originated outside of The City of Palm Springs ‐‐ DO NOT CLICK on links or open attachments unless you are

Mayor Holstege, Mayor Pro Tem Middleton, Councilmember Garner, Councilmember Kors, Councilmember
Woods,
In your discussion tomorrow of revisions to the General Plan Land Use map, I strongly urge you to recommend
that the land use designation of the Palm Hills area be changed from Estate Residential (the portion of Sec 32
with roads shown below) and Special Policy Area (the remainder of the property Secs 31 & part of 32) to Open
Space Mountain, which is the designation of the land to the north, west and south.
Some background. Back in 2005 I was part of the group that placed the successful Measure C referendum on
the ballot to rescind the City Council’s approval of a massive development of Palm Hills (see our Desert Sun ad
below).
2
Now, in 2021, you have the opportunity to finally fulfill the community's desire that Palm Hills be open space.
As the email from the Oswit Land Trust indicates, there is no certainty of acquisition of the property as conservation
land. Now is the time to change the land use designation so that there will at least be some protection of this
incredibly important natural resource for future generations.
Thank you.

RE: City of Palm Springs Limited General Plan Update
Dear Development Services Department,
On behalf of the Southwest Regional Council of Carpenters (“Commenter” or
“Carpenter”), my Office is submitting these comments on the City of Palm Springs’
(“City”) General Plan Community Workshop #2 for its Limited General Plan Update
of the Land Use, Circulation, Housing, and Safety Elements. (“Project”).
The Southwest Carpenters is a labor union representing more than 50,000 union
carpenters in six states and has a strong interest in well ordered land use planning and
addressing the environmental impacts of development projects.
Individual members of the Southwest Carpenters live, work and recreate in the City
and surrounding communities and would be directly affected by the Project’s
environmental impacts.
Commenters expressly reserves the right to supplement these comments at or prior to
hearings on the Project, and at any later hearings and proceedings related to this
Project. Cal. Gov. Code § 65009(b); Cal. Pub. Res. Code § 21177(a); Bakersfield Citizens
for Local Control v. Bakersfield (2004) 124 Cal. App. 4th 1184, 1199-1203; see Galante
Vineyards v. Monterey Water Dist. (1997) 60 Cal. App. 4th 1109, 1121.
Commenters incorporates by reference all comments raising issues regarding the EIR
submitted prior to certification of the EIR for the Project. Citizens for Clean Energy v City

of Woodland (2014) 225 Cal. App. 4th 173, 191 (finding that any party who has objected
to the Project’s environmental documentation may assert any issue timely raised by
other parties).
Moreover, Commenter requests that the Lead Agency provide notice for any and all
notices referring or related to the Project issued under the California Environmental
Quality Act (“CEQA”), Cal Public Resources Code (“PRC”) § 21000 et seq, and the
California Planning and Zoning Law (“Planning and Zoning Law”), Cal. Gov’t
Code §§ 65000–65010. California Public Resources Code Sections 21092.2, and
21167(f) and Government Code Section 65092 require agencies to mail such notices to
any person who has filed a written request for them with the clerk of the agency’s
governing body.
The City should require the use of a local skilled and trained workforce to benefit the
community’s economic development and environment. The City should require the
use of workers who have graduated from a Joint Labor Management apprenticeship
training program approved by the State of California, or have at least as many hours of
on-the-job experience in the applicable craft which would be required to graduate from
such a state approved apprenticeship training program or who are registered
apprentices in an apprenticeship training program approved by the State of California.
Community benefits such as local hire and skilled and trained workforce requirements
can also be helpful to reduce environmental impacts and improve the positive
economic impact of the Project. Local hire provisions requiring that a certain
percentage of workers reside within 10 miles or less of the Project Site can reduce the
length of vendor trips, reduce greenhouse gas emissions and providing localized
economic benefits. Local hire provisions requiring that a certain percentage of workers
reside within 10 miles or less of the Project Site can reduce the length of vendor trips,
reduce greenhouse gas emissions and providing localized economic benefits. As
environmental consultants Matt Hagemann and Paul E. Rosenfeld note:
[A]ny local hire requirement that results in a decreased worker trip length
from the default value has the potential to result in a reduction of
construction-related GHG emissions, though the significance of the
reduction would vary based on the location and urbanization level of the
project site.

March 8, 2021 SWAPE Letter to Mitchell M. Tsai re Local Hire Requirements and
Considerations for Greenhouse Gas Modeling.
Skilled and trained workforce requirements promote the development of skilled trades
that yield sustainable economic development. As the California Workforce
Development Board and the UC Berkeley Center for Labor Research and Education
concluded:
. . . labor should be considered an investment rather than a cost – and
investments in growing, diversifying, and upskilling California’s workforce
can positively affect returns on climate mitigation efforts. In other words,
well trained workers are key to delivering emissions reductions and
moving California closer to its climate targets.1
Local skilled and trained workforce requirements and policies have significant
environmental benefits since they improve an area’s jobs-housing balance, decreasing
the amount of and length of job commutes and their associated greenhouse gas
emissions. Recently, on May 7, 2021, the South Coast Air Quality Management
District found that that the “[u]se of a local state-certified apprenticeship program or
a skilled and trained workforce with a local hire component” can result in air pollutant
reductions.2
Cities are increasingly adopting local skilled and trained workforce policies and
requirements into general plans and municipal codes. For example, the City of
Hayward 2040 General Plan requires the City to “promote local hiring . . . to help
achieve a more positive jobs-housing balance, and reduce regional commuting, gas
consumption, and greenhouse gas emissions.”3

In fact, the City of Hayward has gone as far as to adopt a Skilled Labor Force policy
into its Downtown Specific Plan and municipal code, requiring developments in its
Downtown area to requiring that the City “[c]ontribute to the stabilization of regional
construction markets by spurring applicants of housing and nonresidential
developments to require contractors to utilize apprentices from state-approved, joint
labor-management training programs, . . .”4 In addition, th
