Urban Forest Management Report
• Include coordination with community organizations and One -PS on partnering
opportunities maintaining and preserving the City's public trees
• Clarify how trees are a "threat' and why
• Clarify which trees are causing issues with the City's urban forest
Staff has coordinated with ArborPro, Inc., to update and revise the Tree Inventory to
address the questions raised by the City Council on June 17, 2015; a copy of the Final
Tree Inventory is included as Attachment 2. This staff report provides the information
requested by City Council, and the Tree Inventory has been updated accordingly. The
following highlights the important elements noted in the Tree Inventory:
• ArborPro created 15,224 individual GIS-based public tree records, including 13,830
trees, 220 tree stumps and 1,174 vacant planting sites
45% of surveyed trees have trunk diameters of 12" or smaller
• 85% of surveyed trees are considered in fair or better condition
• 38% of surveyed trees are of the Washingtonia palm species (Mexican and California
Fan Palms)
• The City's public trees intercept 6.8 Million gallons of water annually saving $33,304
• The City's public trees capture 620,065 pounds of carbon dioxide annually
• 2% of surveyed trees have poor health condition warranting 'Priority 1 Pruning"
• 1 % of surveyed trees have poor health condition warranting `Priority 1 Removal"
• 76% of surveyed trees have adequate health condition requiring routine pruning
Based on the Final Tree Inventory, the following Action Plan is recommended:
Action Plan
Staff recommends the following Action Plan with regard to those trees that are in poor
health:
• Proceed with Priority 1 Tree Removals identified as the 111 trees listed in Appendix C
of the Tree Inventory, through an Invitation to Bid and contract to be awarded by the
City Council at a future date, to be completed within one year
• Proceed with Priority 1 Tree Pruning identified in the Tree Inventory, through improved
coordination with the City's landscape maintenance contractor (Golden Valley
Construction) as part of its annual tree trimming and pruning schedule
• Annually review the health of the trees listed as Priority 2 Prune or Priority 2/3
Removal and confirm health of tree warrants removal
• Coordinate annual routine tree trimming and pruning by the City's landscape
maintenance contractor in consultation with a certified Arborist

Community Participation
The Office of Sustainability has recently released a Legacy Tree Program which promotes
community participation and funding to support the City's long-term maintenance of its
urban forest, in particular with irrigation retrofit to sustain public trees currently irrigated
with turf spray irrigation with individual tree bubblers and drip irrigation. A copy of the
Legacy Tree Program information is included as Attachment 3. The Tree Legacy
Program is in addition to and supplements the City's existing Parks Beautification and
Tree Program promoted by the City's Parks and Recreation Department; a copy of the
Beautification and Tree Program brochure is included as Attachment 4.
The Office of Sustainability will initiate efforts to promote the public's participation in
improving and maintaining the City's urban forest by regular announcements through the
Sustainability Commission and the Office of Neighborhood Involvement / One -PS.
Public Tree "Hazards"
The draft Tree Inventory referenced the fact that certain trees posed a threat and hazard,
without clarifying what threats or hazards were represented by those trees. Generally,
public trees that are in very poor health, or are dead, constitute a fire hazard as
referenced in Section 11.72.020 of the Palm Springs Municipal Code:
11.72.020 Fire hazard.
All dry, dead shrubs, dead trees, combustible refuse and waste, or any material growing
upon the streets, sidewalks or upon private property within the city, which by reason of
their size, manner of growth and location constitute a fire hazard to any building,
improvements, crops or other property, or when dry, will in reasonable probability
constitute such a fire hazard, are a public nuisance
Chapter 93.19 of the City's Zoning Code includes general property maintenance
standards requiring a "standard of maintenance" that ...guards against unsafe and
unhealthful conditions which can cause neighborhood deterioration ... (with) landscaping
improvements ... maintained in a healthy condition ... (which) shall include, but not be
limited to ... trees which are trimmed and pruned to retain their health and adequate
clearance over pedestrian and vehicular areas.
The public trees surveyed and identified in the Tree Inventory with a critically poor health
condition were considered to have one or more defects that cannot be cost-effectively or
practically remedied. The Tree Inventory considers a tree with a poor health condition to
be a ...tree (that) appears healthy, but may have structural defects. This classification
also includes healthy trees that have unbalanced structures or have been topped. Trees
in this category may also have severe mechanical damage, decay, severe crown dieback
or poor vigorlfailure to thrive.
The hazard represented by public trees in poor health is that the tree may become
uprooted or have deteriorated branches blown free during severe wind storms, potentially

Urban Forest Management Report
causing damaged to public or private property. There are 111 public trees identified with a
poor health condition warranting consideration for immediate removal, identified as the
"Priority 1 Tree Removals." The issues associated with trees in deteriorating or poor
health is that they require funding resources to address the tree removals or major
trimming and pruning required to protect the trees, and if unchecked, decrease the overall
health of the City's urban forest. The critical issue is documenting the current health of the
urban forest, identifying the lack of appropriate tree maintenance via routine tree trimming
and pruning under the careful guidance of a certified Arborist, and ensuring tree
maintenance is regularly provided following proper arborist guidelines.
ENVIRONMENTAL IMPACT:
Section 21084 of the California Public Resources Code requires Guidelines for
Implementation of the California Environmental Quality Act ("CEQA"). The Guidelines
are required to include a list of classes of projects which have been determined not to
have a significant effect on the environment and which are exempt from the provisions
of CEQA. In response to that mandate, the Secretary for Resources identified classes
of projects that do not have a significant effect on the environment, and are declared to
be categorically exempt from the requirement for the preparation of environmental
documents. In accordance with Section 15301 "Existing Facilities," Class 1 projects
consist of the operation, repair, maintenance, permitting, leasing, licensing, or minor
alteration of existing public or private structures, facilities, mechanical equipment, or
topographical features, involving negligible or no expansion of use beyond that existing
at the time of the lead agency's determination. More specifically, Class 1(h) projects
include maintenance of existing landscaping, and implementing an Action Plan as
identified in the Tree Inventory is therefore considered Categorically Exempt from
CEQA.
FISCAL IMPACT:
The City Council previously awarded a contract to Golden Valley Construction ("GVC")
for landscape maintenance services, which includes annual tree trimming and pruning.
Staff will coordinate with GVC to review their tree trimming and pruning standards and
verify that all such services are coordinated and supervised by a certified Arborist as
mandated by the City's contract. Costs associated with the Priority 1 Tree Pruning are
covered by the contract with GVC.
The Priority 1 Tree Removals are estimated to cost $50,000 (at an estimated cost of
approximately $500 per tree). Staff will prepare an Invitation to Bid to obtain bids for
removal of the 111 trees identified in the Tree Inventory, and return for City Council
award. It is anticipated that funding for the tree removals will be appropriated from the
Sustainability Fund in unallocated funds (Account No. 138-1270-42691).

CITY COUNCIL STAFF REPORT
DATE: June 17, 2015
CONSENT CALENDAR
SUBJECT: CITY OF PALM SPRINGS TREE INVENTORY AND URBAN FOREST
MANAGEMENT REPORT
FROM: David H. Ready, City Manager
BY: Office of the City Manager
SUMMARY
The City of Palm Springs received a grant from the Southern California Association of
Government's (SCAG) Green Region Initiative to conduct a tree inventory, obtain urban
forestry management software and complete an urban forestry management plan. The
grant has provided the City with a full and complete `tree inventory' from which staff can
appropriately manage on -going tree maintenance and replacement.
RECOMMENDATION:
Receive and file.
STAFF ANALYSIS:
In the last five years, the City of Palm Springs has initiated steps towards achieving
recognition as a "Tree City USA" designation through the National Arbor Foundation.
Some of the steps taken include hosting an annual Arbor Day event, education and
outreach to schools regarding the importance of trees and community tree plantings.
The Tree City USA program is a national program that provides the framework for
community forestry management for cities and towns across America. Communities
achieve Tree City USA status by meeting four core standards of sound urban forestry
management, including: (1) maintaining a tree board or department, (2) having a
community tree ordinance, (3) spending at least $2 per capita on urban forestry, and (4)
officially celebrating Arbor Day. By conducting a tree inventory and creating a plan the
City of Palm Springs is not only taking a another step towards this goal, but also will
yield many positive financial savings, reduced maintenance cost and time and
increased community and environmental health.
In recent years, the City has established strong partnerships with many local and
national organizations Including the Arbor Day Foundation, CAL Fire, Western Chapter
G7
City Council Staff Report
June 17, 2015 -- Page 2
Tree Inventory and Urban Forestry Management Report
of the International Society of Arboriculture, Riverside County Master Gardener
Program, Desert Healthcare Foundation and all local schools. Each year the City works
with a local school to host an Arbor Day Celebration. Every child at the school receives
a tree to take home and plant. In 2013, the City was awarded a grant through CAL Fire
and the Britton Fund to host a nationally acclaimed program called Tree Circus. This
program educates community members of all ages about the value and importance of
trees. These valuable partnerships will continue and will help further the work and
educational opportunities that result from a comprehensive Urban Forestry
Management Plan.
Recently, the City's Office of Sustainabillty applied for and received grant award valued
at $80,000 in services from SCAG. After receipt of the grant, SCAG awarded a contract
to ArborPro, Inc., as a vendor to SCAG assigned to the City of Palm Springs to collect
and analyze its public tree inventory. ArborPro employed an International Society of
Arboriculture (ISA) Certified Arborist to collect tree attributes and to GPS locate the
coordinates of every publicly owned and maintained tree in the City. ArborPro collected
attributes such as species, diameter, condition, maintenance need, general
observations, clearance requirements, hardscape damage, proximity to overhead power
lines and grow space. ArborPro utilized handheld surveying equipment to determine the
location of each tree (to sub -meter accuracy) and uploaded the data to a GIS
(Geographic Information System) database. ArborPro provided the City with a license to
ArborPro Tree Management software which allows the tree inventory data to be
managed and updated.
Up until 2013, the City had never conducted a comprehensive inventory of publicly
owned and maintained trees, and no management tool had ever been implemented to
monitor and maintain these trees. This lack of data only allowed for reactive urban
forest management, rather than management through a comprehensive, systematic
approach. By preparing a tree inventory, the City has taken the critical first step to being
able to proactively and efficiently manage its urban forest.
The final report, titled City of Palm Springs Inventory of Public Trees (2014) 1 Urban
Forest Management Report is included as Attachment 1. The inventory has identified
various characteristics of the City's urban forest (those publicly owned and maintained
trees), consisting of 15,224 various trees, which include tree diameter (diameter at
breast height (DBH]), tree height, and tree condition, as represented in the Tables on
the following page.

Tree Inventory and Urban Forestry Management Report
The objective of the tree inventory and urban forestry management report is to
summarize the findings from the tree inventory and to provide recommendations an how
to appropriately manage the City's urban forest. The goal of the plan is to lay the
foundation for long-term urban forestry programming.
ENVIRONMENTAL IMPACT:
Section 15061 (b)(3) of the California Environmental Quality Act ("CEQA") Guidelines
exempts activities that are covered under the general rule that CEQA applies only to
projects that have the potential to cause significant effects on the environment. Where
it can be seen with certainty that there is no possibility the activity in question may have
a significant effect upon the environment, the activity is not subject to CEQA. The
requested action requests the City Council to receive and file the tree inventory and
urban forest management report, which itself will not result In any new direct physical
impacts to the environment. Therefore, the requested action is considered exempt from
CEQA.
FISCAL IMPACT:
There is no direct local fiscal impact associated with the requested action.

Inventory Summary
ArborPro, Inc. collected a variety of attributes for each tree in the City, including its size,
species and maintenance requirements. The purpose of this section is to summarize the
data which was collected.
Number of Trees
During the data collection process, ArborPro, Inc. created 15,224 records, which includes
13,830 trees, 220 stumps and 1,174 vacant planting sites.
Size Characteristics
The general size of a tree provides insight into the age and value of the tree. There are
two industry wide recognized size characteristics: height and diameter at breast height.
While height is self explanatory, diameter at breast height (DBH) is determined by the
diameter of the tree at 4.5' above grade. Both the Height and DBH are collected in
ranges due to the dynamic growth rate of trees.
The chart below summarizes the DBH distribution among the trees collected:

The charts above indicate that the City of Palm Springs has a relatively young urban
forest. With regards to the Diameter at Breast Height (trunk diameter) 45% of the trees
surveyed are 12 inches or smaller. As the urban forest becomes more [nature, the young
trees will become larger and the distribution of DBH and height will shift to the right.
In general, large mature trees provide significantly greater aesthetic and environmental
benefits than young small trees. Proper maintenance and management of the urban forest
will allow the young trees to grow larger and deliver the increased benefits to the City.
Tree Condition
A condition assessment was conducted for every tree that was cataloged as part of the
tree inventory. The condition assessment was based on criteria established by the ISA.
Each tree was assigned a rating (exceilen4 very good, good, fair, poor, dead and critical).
A description of the rating categories arc below:
Excellent — The tree is new perfect condition, this determination is generally used
for trees with no defects and young trees that have been properly maintained.
Very Good — The tree is in very good condition with very mirror defects that
could be corrected by pruning. These trees generally "stand out" with respect to
the aesthetic value they add to the Urban Forest.
Good — The tree has no major structural problems; no significant damage from
diseases or pests; no significant mechanical damage; a full, balanced crown, and
normal twig condition and vigor for its species.
Fair — The tree may exhibit the following characteristics: minor structural
problems and/or mechanical damage; significant damage from ran -fatal or
disfiguring diseases; minor crown imbalance or thin crown; minor structural
imbalance; or stunted growth compared to adjacent trees.
Poor — The tree appears healthy, but may have structural defects. This
classification also includes healthy trees that have unbalanced structures or have
been topped. Trees in this category may also have severe mechanical damage,
decay, severe crown dieback or poor vigor/failure to thrive.
Dead — Trees in advanced states of decline are not included. This category refers
only to dead trees.
Critical — The tree is in a physical state that requires immediate attention.
Generally these trees are recommended for a Priority One Removal.
The charts below summarize the distribution of tree conditions.

About 86a/a of trees surveyed, were given a rating of"fair" or better, which is indicative
of a fairly healthy urban forest. The vast majority of trees surveyed fell within the "good"
or "fair" condition categories. Moving forward, it is important to perform proper
maintenance of the urban forest to maintain or improve this overall condition level.
Species Distribution
The City of Palm Springs does not have the most diverse Urban Forest. Of the 13,803
trees that were surveyed, 40% of the trees are Washingtonia Palm species, Mexican and
California Fan Palms. The palm trees are iconic to the City of Palm Springs and provide
many aesthetic benefits, however, they do not provide as many environmental benefits as
other trees would provide for the City. As part of our long term management strategy we
are recommending the introduction of additional evergreen and deciduous species to be
planted city wide.
In general, a diverse palette of trees helps guard against catastrophic loss to insects and
diseases or environmental stresses.

Economic Benefits Analysis
Often, municipalities only consider the cost of maintaining the urban forest, and ignore
the benefits that trees provide. Trees provide significant community benefits. It is
important to quantify those benefits to highlight the fact that trees are a good investment
for the community.
ArborPro, Inc. performed an economic benefits analysis of the tree inventory data
utilizing the i-Tree software suite distributed by the USDA Forest Service. The i-Tree
suite is comprised of urban and community forestry analysis and benefits assessment
tools. The i-Tree tools are intended to help communities to strengthen their urban forest
management and advocacy efforts by quantifying the environmental services that trees
provide and the structure of the urban forest. All of the attributes collected during the tree
inventory were entered into the i•Tree software to quantify their value.
Stormwater Runoff and Improved Water Quality
Trees reduce peak stormwater runoff and associated pollutants entering local water
bodies. Trees reduce stormwater volumes by intercepting a portion of rainfall, which
evaporates and never reaches the ground. Tree roots also increase rainfall infiltration and
storage in the soil. And tree canopies reduce soil erosion by diminishing the impact of
raindrops on barren surfaces.
Public trees in Palm Springs intercept 6,882,183 gallons of water annually for a savings
of 533,304.
Reduction of Atmospheric Carbon DIoxide
Trees reduce atmospheric carbon by capturing and storing CO2 as they grow. By
reducing demand for heating and cooling, trees indirectly reduce CO2 by avoiding
emissions associated with energy production.
Public trees in Palm Springs capture 620,065 pounds of atmospheric CO2 per year.
Annual savings including indirect costs are $4,650. Street trees also store approximately
14,414,657 pounds of atmospheric CO2 for a total savings of 5108,110.
Air Quality Improvements
Trees improve air quality by trapping particulates, absorbing gaseous pollutants, and
releasing oxygen. By cooling urban heat islands and shading parked cars, trees indirectly
reduce ozone levels. The Environmental Protection Agency recognizes tree planting as an
ozone reduction measure in state implementation plans.
12 Prepared by ArborPro, Inc. 23
Public trees in Palm Springs remove particulate matter, ozone, sulfur dioxide and
nitrogen oxides. The annual savings from air quality improvements including indirect
cost is S 37,208,
Energy Savings
Trees reduce the demand for energy to heat and cool buildings by providing shade,
lowering summertime temperatures, and reducing windspeeds. Secondary benefits are
reduced water consumption and pollutants emissions.
Public trees in Palm Springs save approximately 406.3 MWH of electricity and 7.226.6
Therms of natural gas annually for a savings of $63,186,
Improved Property Values
Trees are the single strongest positive influence on scenic quality in most communities.
They increase the attractiveness of retail business areas. Studies have found that shoppers
are willing to pay more for goods and services in a well -landscaped business district and
people will pay more for properties with many trees. Trees foster safer and more sociable
neighborhoods. Views of trees ease mental fatigue and stress, help concentration, reduce
sickness, and provide settings for recreation and relaxation. Trees also help reduce noise,
provide a refuge for wildlife, and help connect residents with their natural environment.
Public trees in Palm Springs increase property values annually by $307,572.
The full i-Tree reports are provided in Exhibit C.
The i-Tree reports indicate that larger trees provide significantly greater environmental
and economic benefits to the community than smaller trees. For example, the average
annual benefits for individual African Sumac Trees were calculated to be $47.53,
whereas the average annual benefits for individual Mexican Fan Pals was calculated to be
$12.80. As the City's urban forest continues to grow, it is expected that the difference in
average annual benefits will grow by a large margin.

Tree Maintenance Recommendations
The Certified Arborist that conducted the tree inventory provided a maintenance
recommendation for each tree or tree site. All recommendations and tree assessments
were provided utilizing a ground level observation of the tree. There can be unforeseen
damage internally or in the branch structure, not identified by the data collector, that
could cause limb or tree failure. The maintenance categories are defined below:
Priority One Prune — Trees which require pruning to remove deadwood and/or
broken branches that pose an immediate safety risk that could result in personal
injury or property damage. Trees have limbs that are more than 3 inches in
diameter and pose an immediate safety risk. The trees that have been
recommended for a priority I prune should be inspected by staff. These trees are
in need of corrective maintenance.
Priority Two Prune — Trees having problems and conditions which may affect
future safety, health or structure of the tree. This includes primarily large trees
(over 20 feet in height) with mirror amounts of deadwood and correctable
structural problems.
Routine Prune (Small or Large) — This includes pruning of trees with minor
amounts of deadwood that pose little or no threat of personal injury or property
damage and trees with correctable structural problems. Trees with growth patterns
that will eventually obstruct or interfere with pedestrian or vehicular traffic, traffic
control devices, lines of sight, or overhead utility lines are also included in this
category. These trees are in satisfactory condition and can be pruned on a regular
cycle.
Priority One Removal — Trees that are dead or have one or more defects that
cannot be cost-effectively or practically remedied. Such defects include extensive
trunk decay and severely decayed or weakened v-type crotches. These trees
should be surveyed by staff and scheduled for removal and replacement if
appropriate. This category includes trees that reflect dangerous conditions
combined with significant targets such as proximity to high volume sidewalks or
play areas.
Priority Two Removal - Trees that are structurally compromised but may be
expected to be removed in 2 to 5 years. These trees should be scheduled for
removal over a reasonable time period based on available funds. The removal
process should be followed by a replanting program.
Plant Tree — This recommendation has been provided for vacant planting sites
throughout the city. Based on criteria approved by the City of Palm Springs our
data collector has identified sites throughout the city to plant trees. In association
14 Prepared by ArborPro, Inc. 25
with the Planting Plan we have also identified the appropriate specie to plant in
each site.
Training Prune — The most important time to prune a tree is within the first five
years following planting- By properly pruning a young tree the city will save
future maintenance costs that result from poor branch structure, dual leaders, etc.
The small investment on a young tree will save thousands in the long run.

Hazard Eradication
The trees that pose the most immediate threat to the City of Palm Springs are categorized
as Category I Removals. The first phase of properly managing the City's tree inventory
is to remove the trees in the Priority I Removal category. Utilizing the ArborPro software
provided, city staff can produce a work order and map to generate an RFP and to create a
work order to remove all Category I Removal trees. It is recommended that the City
remove these trees as soon as possible to reduce liability. If the city is not able to fund the
removal of all of the hazardous trees in one year, the city may consider a multi -year
removaUreplacement program, not to exceed three years. In a multi -year plan, the City
should remove the most hazardous trees in year one and work their way through the list.
ArborPro, Inc. strongly suggests that the program does not exceed a three year tern.
Removing all trees at one time, under one contract would provide the City with some cost
savings.

Tree Pruning Program
Pruning is the most common tree maintenance procedure. Although forest trees grow
quite well with only natures pruning, landscape trees require a higher level of care to
maintain their safety and aesthetics. Pruning should be done with an understanding of
how the tree responds to each cut. Improper pruning can cause damage that will last for
the life of the tree, or worse, shorten the tree's life.
Because each cut has the potential to change the growth of the tree, no branch should be
removed without a reason. Common reasons for pruning are to remove dead branches, to
remove crowded or rubbing limbs, and to eliminate hazards. Trees may also be pruned to
increase light and air penetration to the inside of the tree's crown or to the landscape
below. In most cases, mature trees are pruned as a corrective or preventive measure.
Routine thinning does not necessarily improve the health of a tree. Trees produce a dense
crown of leaves to manufacture the sugar used as energy for growth and development.
Removal of foliage through pruning can reduce growth and stored energy reserves.
Heavy pruning can be a significant health stress for the tree.
Yet if people and trees are to coexist in an urban or suburban environment, then we
sometimes have to modify the trees. City environments do not mimic natural forest
conditions. Safety is a major concern. Also, we want trees to complement other landscape
plantings and lawns. Proper pruning, with an understanding of tree biology, can maintain
good tree health and structure while enhancing the aesthetic and economic values of our
landscapes.
ArborPro. Inc. recommends that the City of Palm Springs deploy a routine tree trimming
program based on a pre -determined grid system. Based on volume and efficiencies of
maintaining the Imes on a block by block basis the City will receive a fair price for the
maintenance and be able to properly and efficiently manage the Urban Forest. Prior to
the implementation of the routine tree trimming program we suggest that the City address
the trees that have been recommended as Priority I Prunes. We have identified only 199
trees that fall into this category but they should be addressed in the near future. Based on
recent local bid results we predict the cost for this maintenance will not exceed $30,000.

ArborPro Software
To maintain the integrity of the tree inventory, it is important that data be properly
maintained and updated. When a tree is pruned, removed or planted, the information
should be updated in the ArborPro tree management program. When preparing a contract
for a tree management services, the City should include a provision requiring the
company to update the ArborPro database.

Tree Planting Recommendations
To have a healthy and functional urban forest, it is important to have the right trees
planted in the right place. For example, it would not be appropriate to plant a tall growing
redwood tree directly underneath utility lines. ArborPro, Inc. has developed a
recommended planting palette to provide city staff with a guide to aid in the proper
selection of a species that is appropriate to a particular planting site and its physical
characteristics.
Recommended Species Characteristics
Not all existing species within the city meet the criteria for where they are located.
Parkway size is commonly far too narrow and utility lines are a common conflict with
tree canopy. One of the goals of this document is to offer a framework to city staff for
selecting the correct tree for the site condition. In selecting a replacement species these
conditions were evaluated as well as spread and canopy coverage, leaf and fruit litter.
Tree Planting Palette
In association with city staff and utilizing guidelines from the suggested from the
Recommended Street Tree Book, ArborPro, Inc. has created a tree planting palette for the
City of Palm Springs. ArborPro, Inc. suggests that this list remain dynamic. The benefits
of alternate species and cultivars are discovered every year.

The list above is organized by the size of parkway planting area. All of the above trees
have been deemed to be appropriate in an urban planting situation, but offer unique
characteristics. Some trees have showy flowers and others attract insects or wildlife.
Some are evergreen, some are deciduous. Some trees provide edible fruit. All of a free's
characteristics should be taken into account during a tree planting situation, not just the
amount of growing space.
Replacement Program
Utilizing the recommended planting palette, the city should continually replace trees that
have been removed or have failed with new plantings in order to minimize the impact on
the urban forest. ArborPro, Inc. recommends utilizing 24" box trees or larger for
replacement plantings.
In ful Planting
The tree inventory identified 1,174 vacant sites which are potentially suitable for tree
planting. We recommend that the city take a proactive approach to plant trees at these
locations.
The City should always keep in mind that a major wind storm event, pest or disease can
wipe out a large portion of the City's canopy at any time. Therefore, the city should

Background
The City of Palm Springs is emerging as the premier sustainable city in the Coachella
Valley. The City of Palm Springs seeks to deliver educational materials, programs and
events that inspire residents, business and all community members to conserve resources
and improve the environmental welfare of our City. A tree inventory and urban forestry
management plan are an integral component of the comprehensive sustainability program
the City strives to cultivate. In April 2014, The Southern California Association of
Governments (SCAG), in partnership with the City of Palm Springs, solicited proposals
in response to Request for Proposal (RFP) No. 14-001-1334, Urban Forestry Initiative.
The City of Palm Springs awarded a contract to ArborPro, Inc. to collect and analyze tree
inventory data. ArborPro, Inc. employed an International Society of Arboriculture (ISA)
Certified Arborist to collect tree attributes and to GPS locate the coordinates of every
publicly owned and maintained tree in the City. ArborPro Inc. collected attributes such as
species, diameter, condition, maintenance need, general observations, clearance
requirements, hardscape damage, proximity to overhead power lines and grow space.
ArborPro, Inc. utilized handheld surveying equipment to determine the location of each
tree (to sub -meter accuracy) and uploaded the data to a GIS (Geographic Information
System) database. ArborPro, Inc. provided the City of Palm Springs with a license to
utilize the ArborPro Tree Management software which allows the tree inventory data to
be managed and updated.
Up until 2013, the City of Palm Springs had never conducted a comprehensive inventory
of city trees and no management tool had ever been implemented to monitor and maintain
these trees. This lack of data only allowed for reactive urban forest management, rather
than management through a comprehensive, systematic approach. By preparing a tree
inventory, the City of Palm Springs took the critical first step to being able to proactively
and efficiently manage the urban forest.
The objective of this report is to summarize the findings from the tree inventory and to
provide recommendations on how to appropriately manage the City's urban forest.

ArborPro, Inc. collected a variety of attributes for each tree in the City, including its size,
species and maintenance requirements. The purpose of this section is to summarize the
data which was collected.
Number of Trees
During the data collection process, ArborPro, Inc. created 15,224 records, which includes
13,830 trees, 220 stumps and 1,174 vacant planting sites.
Size Characteristics
The general size of a tree provides insight into the age and value of the tree. There are
two industry wide recognized size characteristics: height and diameter at breast height.
While height is self explanatory, diameter at breast height (DBH) is determined by the
diameter of the tree at 4.5' above grade. Both the Height and DBH are collected in
ranges due to the dynamic growth rate of trees.
The chart below summarizes the DBH distribution among the trees collected:

The charts above indicate that the City of Palm Springs has a relatively young urban
forest. With regards to the Diameter at Breast Height (trunk diameter) 45% of the trees
surveyed are 12 inches or smaller. As the urban forest becomes more mature, the young
trees will become larger and the distribution of DBH and height will shift to the right.
In general, large mature trees provide significantly greater aesthetic and environmental
benefits than young small trees. Proper maintenance and management of the urban forest
will allow the young trees to grow larger and deliver the increased benefits to the City.
Tree Condition
A condition assessment was conducted for every tree that was cataloged as part of the
tree inventory. The condition assessment was based on criteria established by the ISA.
Each tree was assigned a rating (excellent, very good, good, fair, poor, dead and critical).
A description of the rating categories are below:
Excellent — The tree is near perfect condition, this determination is generally used
for trees with no defects and young trees that have been properly maintained.
Very Good — The tree is in very good condition with very minor defects that
could be corrected by pruning. These trees generally "stand out' with respect to
the aesthetic value they add to the Urban Forest.
Good — The tree has no major structural problems; no significant damage from
diseases or pests; no significant mechanical damage; a full, balanced crown, and
normal twig condition and vigor for its species.
Fair — The tree may exhibit the following characteristics: minor structural
problems and/or mechanical damage; significant damage from non -fatal or
disfiguring diseases; minor crown imbalance or thin crown; minor structural
imbalance; or stunted growth compared to adjacent trees.
Poor — The tree appears healthy, but may have structural defects. This
classification also includes healthy trees that have unbalanced structures or have
been topped. Trees in this category may also have severe mechanical damage,
decay, severe crown dieback or poor vigor/failure to thrive.
Dead — Trees in advanced states of decline are not included. This category refers
only to dead trees.
Critical — The tree is in a physical state that requires immediate attention.
Generally these trees are recommended for a Priority One Removal.
The charts below summarize the distribution of tree conditions.

About 85% of trees surveyed, were given a rating of"fair" or better, which is indicative
of a fairly healthy urban forest. The vast majority of trees surveyed fell within the "good"
or "fair" condition categories. Moving forward, it is important to perform proper
maintenance of the urban forest to maintain or improve this overall condition level.
Species Distribution
The City of Palm Springs does not have the most diverse Urban Forest. Of the 13,913
trees that were surveyed, 38% of the trees are Washingtonia Palm species, Mexican and
California Fan Palms. The palm trees are iconic to the City of Palm Springs and provide
many aesthetic benefits, however, they do not provide as many environmental benefits as
other trees would provide for the City. As part of our long term management strategy we
are recommending the introduction of additional evergreen and deciduous species to be
planted city wide.

Economic Benefits Analysis
Often, municipalities only consider the cost of maintaining the urban forest, and ignore
the benefits that trees provide. Trees provide significant community benefits. It is
important to quantify those benefits to highlight the fact that trees are a good investment
for the community.
ArborPro, Inc. performed an economic benefits analysis of the tree inventory data
utilizing the i-Tree software suite distributed by the USDA Forest Service. The i-Tree
suite is comprised of urban and community forestry analysis and benefits assessment
tools. The i-Tree tools are intended to help communities to strengthen their urban forest
management and advocacy efforts by quantifying the environmental services that trees
provide and the structure of the urban forest. All of the attributes collected during the tree
inventory were entered into the i-Tree software to quantify their value.
Stormwater Runoff and Improved Water Quality
Trees reduce peak stormwater runoff and associated pollutants entering local water
bodies. Trees reduce stormwater volumes by intercepting a portion of rainfall, which
evaporates and never reaches the ground. Tree roots also increase rainfall infiltration and
storage in the soil. And tree canopies reduce soil erosion by diminishing the impact of
raindrops on barren surfaces.
Public trees in Palm Springs intercept 6,882,183 gallons of water annually for a savings
of $33,304.
Reduction of Atmospheric Carbon Dioxide
Trees reduce atmospheric carbon by capturing and storing CO2 as they grow. By
reducing demand for heating and cooling, trees indirectly reduce CO2 by avoiding
emissions associated with energy production.
Public trees in Palm Springs capture 620,065 pounds of atmospheric CO2 per year.
Annual savings including indirect costs are $4,650. Street trees also store approximately
14,414,657 pounds of atmospheric CO2 for a total savings of $108,110.
Air Quality Improvements
Trees improve air quality by trapping particulates, absorbing gaseous pollutants, and
releasing oxygen. By cooling urban heat islands and shading parked cars, trees indirectly
reduce ozone levels. The Environmental Protection Agency recognizes tree planting as an
ozone reduction measure in state implementation plans.
12 Prepared by ArborPro, Inc. 47
Public trees in Palm Springs remove particulate matter, ozone, sulfur dioxide and
nitrogen oxides. The annual savings from air quality improvements including indirect
cost is $ 37,208.
Energy Savings
Trees reduce the demand for energy to heat and cool buildings by providing shade,
lowering summertime temperatures, and reducing windspeeds. Secondary benefits are
reduced water consumption and pollutants emissions.
Public trees in Palm Springs save approximately 406.3 MWH of electricity and 7,226.6
Therms of natural gas annually for a savings of$63,186.
Improved Property Values
Trees are the single strongest positive influence on scenic quality in most communities.
They increase the attractiveness of retail business areas. Studies have found that shoppers
are willing to pay more for goods and services in a well -landscaped business district and
people will pay more for properties with many trees. Trees foster safer and more sociable
neighborhoods. Views of trees ease mental fatigue and stress, help concentration, reduce
sickness, and provide settings for recreation and relaxation. Trees also help reduce noise,
provide a refuge for wildlife, and help connect residents with their natural environment.
Public trees in Pahn Springs increase property values annually by $307,572.
The full i-Tree reports are provided in Exhibit C.
The i-Tree reports indicate that larger trees provide significantly greater environmental
and economic benefits to the community than smaller trees. For example, the average
annual benefits for individual African Sumac Trees were calculated to be $47.53,
whereas the average annual benefits for individual Mexican Fan Pals was calculated to be
$12.80. As the City's urban forest continues to grow, it is expected that the difference in
average annual benefits will grow by a large margin.

Tree Maintenance Recommendations
The Certified Arborist that conducted the tree inventory provided a maintenance
recommendation for each tree or tree site. All recommendations and tree assessments were
provided utilizing a ground level observation of the tree. There can be unforeseen damage
internally or in the branch structure, not identified by the data collector, that could further
affect the health of the tree. The maintenance categories are defined below:
Priority One Prune — Trees which require pruning to remove deadwood and/or
broken branches that pose a potential safety risk that could most seriously affect
the health of the tree. The trees that have been recommended for a priority 1
prune should be inspected by staff. These trees are in need of corrective
maintenance.
Priority Two Prune — Trees having problems and conditions which may affect
future safety, health or structure of the tree. This includes primarily large trees
(over 20 feet in height) with minor amounts of deadwood and correctable
structural problems.
Routine Prune (Small or Large) — This includes pruning of trees with minor
amounts of deadwood that pose little or no threat to the overall health of the tree.
These trees typically have correctable structural problems. Trees with growth
patterns that will eventually obstruct or interfere with pedestrian or vehicular
traffic, traffic control devices, lines of sight, or overhead utility lines are also
included in this category. These trees are in satisfactory condition and can be
pruned on a regular cycle.
Priority One Removal — Trees that are dead or have one or more defects that
cannot be cost-effectively or practically remedied. Such defects include extensive
trunk decay and severely decayed or weakened v-type crotches. These trees
should be surveyed by staff and scheduled for removal and replacement if
appropriate. This category includes trees that are in very poor health.
Priority Two Removal - Trees that are structurally compromised but may be
expected to be removed in 2 to 5 years. These trees should be scheduled for
removal over a reasonable time period based on available funds. The removal
process should be followed by a replanting program
Plant Tree — This recommendation has been provided for vacant planting sites
throughout the city. Based on criteria approved by the City of Palm Springs our
data collector has identified sites throughout the city to plant trees. In association
14 Prepared by ArborPro, Inc. 49
with the Planting Plan we have also identified the appropriate specie to plant in
each site.
Training Prune — The most important time to prune a tree is within the first five
years following planting. By properly pruning a young tree the city will save
future maintenance costs that result from poor branch structure, dual leaders, etc.
The small investment on a young tree will save thousands in the long run.

Tree Removal Action Plan
The first phase of properly managing the City's Urban Forest is to remove the trees in the
Priority 1 Removal category. Utilizing the ArborPro software provided, city staff can
produce a detailed listing and map of all of the Priority 1 Removal locations. This
information can be included in an RFP for distribution to local tree maintenance firms. It
is recommended that the City remove these trees as soon as possible to reduce liability. If
the city is not able to fund the Priority 1 Removal trees in one year, the city may consider
a multi -year removal/replacement program, not to exceed three years. In a multi -year
plan, the City should remove the trees with the poorest health conditions in year one and
work their way through the list. ArborPro, Inc. strongly suggests that the program does not
exceed a three year term. Removing all trees at one time, under one contract would
provide the City with some cost savings.

Tree Pruning Program
Pruning is the most common tree maintenance procedure. Although forest trees grow
quite well with only nature's pruning, landscape trees require a higher level of care to
maintain their safety and aesthetics. Pruning should be done with an understanding of
how the tree responds to each cut. Improper pruning can cause damage that will last for
the life of the tree, or worse, shorten the tree's life.
Because each cut has the potential to change the growth of the tree, no branch should be
removed without a reason. Common reasons for pruning are to remove dead branches, to
remove crowded or rubbing limbs, and to eliminate vertical obstructions due to
overgrown trees. Trees may also be pruned to increase light and air penetration to the
inside of the tree's crown or to the landscape below. In most cases, mature trees are
pruned as a corrective or preventive measure.
Routine thinning does not necessarily improve the health of a tree. Trees produce a dense
crown of leaves to manufacture the sugar used as energy for growth and development.
Removal of foliage through pruning can reduce growth and stored energy reserves.
Heavy pruning can be a significant health stress for the tree.
Yet if people and trees are to coexist in an urban or suburban environment, then we
sometimes have to modify the trees. City environments do not mimic natural forest
conditions. Safety is a major concern. Also, we want trees to complement other landscape
plantings and lawns. Proper pruning, with an understanding of tree biology, can maintain
good tree health and structure while enhancing the aesthetic and economic values of our
landscapes.
The contractor recommends that the City of Palm Springs deploy a routine tree trimming
program based on a pre -determined grid system. Based on volume and efficiencies of
maintaining the trees on a block by block basis the City will receive a fair price for the
maintenance and be able to properly and efficiently manage the Urban Forest. Prior to
the implementation of the routine tree trimming program we suggest that the City address
the trees that have been recommended as Priority 1 Prunes. We have identified only 223
trees that fall into this category but they should be addressed in the near future. Based on
recent local bid results we predict the cost for this maintenance will not exceed $38,000.

Palm Springs - Priority 1 Pruning
ArborPro Software
To maintain the integrity of the tree inventory, it is important that data be properly
maintained and updated. When a tree is pruned, removed or planted, the information
should be updated in the ArborPro tree management program. When preparing a contract
for a tree management services, the City should include a provision requiring the
company to update the ArborPro database.

Tree Planting Recommendations
To have a healthy and functional urban forest, it is important to have the right trees
planted in the right place. For example, it would not be appropriate to plant a tall growing
redwood tree directly underneath utility lines. ArborPro, Inc. has developed a
recommended planting palette to provide city staff with a guide to aid in the proper
selection of a species that is appropriate to a particular planting site and its physical
characteristics.
Recommended Species Characteristics
Not all existing species within the city meet the criteria for where they are located.
Parkway size is commonly far too narrow and utility lines are a common conflict with
tree canopy. One of the goals of this document is to offer a framework to city staff for
selecting the correct tree for the site condition. In selecting a replacement species these
conditions were evaluated as well as spread and canopy coverage, leaf and fruit litter.
Tree Planting Palette
In association with city staff and utilizing guidelines from the suggested from the
Recommended Street Tree Book, ArborPro, Inc. has created a tree planting palette for the
City of Palm Springs. ArborPro, Inc. suggests that this list remain dynamic. The benefits
of alternate species and cultivars are discovered every year.

The list above is organized by the size of parkway planting area. All of the above trees
have been deemed to be appropriate in an urban planting situation, but offer unique
characteristics. Some trees have showy flowers and others attract insects or wildlife.
Some are evergreen, some are deciduous. Some trees provide edible fruit. All of a tree's
characteristics should be taken into account during a tree planting situation, not just the
amount of growing space.
Replacement Program
Utilizing the recommended planting palette, the city should continually replace trees that
have been removed or have failed with new plantings in order to minimize the impact on
the urban forest. ArborPro, Inc. recommends utilizing 24" box trees or larger for
replacement plantings.
In fill Planting
The tree inventory identified 1,174 vacant sites which are potentially suitable for tree
planting. We recommend that the city take a proactive approach to plant trees at these
locations.
The City should always keep in mind that a major wind storm event, pest or disease can
wipe out a large portion of the City's canopy at any time. Therefore, the city should
23 Prepared by ArborPro,Inc. 58
constantly fill vacant sites in anticipation of potential future canopy loss. It can take
decades to replace the canopy of a mature tree. If trees are continually planted, the impact
from a catastrophic loss of trees is diminished. ArborPro, Inc. recommends utilizing 24"
box trees or larger for new plantings, but in special situations or with budget limitations,
a 15 gallon planting or planting by seed may also be acceptable.
Community Outreach
Customer service is important to all companies and cities. ArborPro, Inc. recommends
that a mailer or door hanger be distributed to properties located near a site where a tree is
planned to be removed, pruned or planted. This step will take minimal effort and expense
and almost always results in more satisfied customers (residents).
Young Tree Maintenance Program
Young trees require special maintenance. New tree plantings must be done in conjunction
with a funded young tree maintenance program.
The most important maintenance performed on any tree takes place in the first 2-5 years.
Trimming a young tree provides exponential benefits. Proper pruning of a young tree,
utilizing International Society of Arboriculture standards, will promote a healthy growth
and form. Many pruning activities performed by crews, on mature trees, is the result of
neglect of young trees or poor past pruning techniques. With a little effort in the first 2-5
years a properly pruned tree will not require very much attention in the future. Young
tree maintenance is a very inexpensive activity and will save the city thousands of dollars
in future maintenance and potential liability.
New plantings typically require several years of regular watering for the tree to properly
establish. Irrigation systems or a program for hand watering should be established for the
first several years after a tree is planted. ArborPro Inc. recommends recruiting nearby
residents to assist with the watering needs of a new tree. Residents are often very willing
to help water because new trees ultimately improve the appearance of their property and
their streetscape.
Tree Planting Funding Sources
Grant opportunities arise periodically that will fund tree planting activities. Over the past
several years, CAL FIRE grants have funded numerous planting efforts. Palm Springs
should submit a grant application to plant trees on the vacant planting sites identified in
the tree inventory. Having specific locations identified is a desirable characteristic in a
tree planting grant application.
The City may also be able to fund new tree plantings by simply working with local
community groups. Many organizations will donate time and money to support local tree
planting efforts. The City should approach local non-profit organizations and
neighborhood groups with a plan for small community based tree planting events.

Construction Management
Capital projects or private developments often conflict with existing mature trees. Proper
management and protection of existing trees is important when conducted in conjunction
with a development project.
ArborPro, Inc. recommends that a Certified Arborist be consulted when any grading,
paving or other construction work is to be conducted within the canopy of an existing
mature tree. Some species will be incompatible with a construction project. A Certified
Arborist can determine whether it is appropriate to preserve the tree and if so, can provide
recommendations for adequately protecting it during construction. Consultation should be
done during the design phase, if possible.

MEDIA ALERT
Honor a Friend or Loved One with a Living Legacy
Would you like to memorialize a friend or loved one with a living tree? Want to
show that you, a friend or your organization is an active, contributing member of
the community? The City of Palm Springs has a tree adoption program designed
with these purposes in mind.
In these times of drought the City of Palm Springs is seeking funding to ensure our
City's trees survive. With irrigation changes that resulted as we stopped watering
turf the need arose to add bubblers and ensure special watering is arranged for our
trees to stay alive. By adopting a Legacy Tree you can help make this happen.
Once a tree has been dedicated it becomes a perfect meeting place for families or
groups. Trees selected must be existing and within the boundaries of the City of
Palm Springs. Any individual or organization is welcome to participate in the
Legacy Tree Adoption Program.
The Legacy Tree program is an innovative approach that the City of Palm Springs
is taking to ensure the health of our urban forest while honoring those special
people, places and organizations in our beloved community. By donating $200.00
to the City's program the applicant receives a beautiful memorial as well as the
assurance that the tree will endure and receive appropriate watering through these
times of drought. The funds from tree adoption will offset costs of changes to
irrigation to accommodate trees during the drought and in perpetuity. You can
choose from a tree hugger, dedication stone or stake sign.

"Parks Beautification and Tree Program"
The purpose of the "Parks Beautification and Tree Program" is to provide members of the
public a means to recognize and honor others with a lasting tribute through the planting
of a tree or the placing of a plaque at an existing tree. Contributions made through this
program may also benefit the City's parks and the community as a whole by using the
funds to maintain our great city.
All requests by persons, clubs, or organizations desiring to commemorate someone
through this program must complete the attached application and submit it to the City's
Parks and Recreation Commission for its review prior to approval.
Location: Commemorative trees shall be limited to the following City parks: Baristo
Park, DeMuth Park, Desert Highland Park, Frances Stevens Park, Palm
Springs Dog Park, Ruth Hardy Park, Sunrise Plaza, and Victoria Park.
Species: Since all tree species are not heat tolerant, commemorative trees shall be
limited to species that thrive in the desert climate. The exact species will
be determined by location in the chosen park and agreed upon prior to
submitting the application to the commission.
Purchase: The contributor will be responsible for payment of $1,000 in advance,
whether for a new or an existing tree. New trees, including a two-year
warranty, will be purchased by the City's Parks Division staff. No
warranties for existing trees will be made available.
Planting: The new tree will be planted by the City's Parks Division staff within 100
days after receipt of payment. If the contributor wishes to host a
ceremony or event in conjunction with the planting, the contributor will be
notified by City staff once the tree has been planted. Placement of
memorial wreaths, flowers or other items will not be permitted.
Maintenance: The City's Parks Division staff will maintain the tree in the same manner
as other park trees. Replacement of a new commemorative tree after the
two-year warranty has expired will be at the discretion of the City.
Plaques: One plaque per tree may be purchased at a cost of $250. The plaque shall
be no larger than 8" x 6" x ''/z" and made of bronze. It will be purchased
by the City's Parks Division staff and placed at the base of the new tree at
the time of planting or at an existing tree within 100 days after receipt of
payment. The test on the plaque shall read as follows:
In Memory of / In Honor of / In Recognition of
Name
Date
75
If a plaque must be replaced due to vandalism or theft within the first two
years after placement, the City will replace it one time at no additional
expense to the contributor. Thereafter, additional replacements will be at
the option and cost of the contributor. Once a plaque has been placed at
the base of a tree, it shall become the property of the City of Palm Springs.
If the contributor wishes to host a ceremony or event in conjunction with
the installation of the plaque at an existing tree, staff will consult with the
contributor to determine feasibility. If no ceremony or event is planned in
conjunction with the installation, the contributor will be notified by City
staff once the plaque has been installed. Placement of memorial wreaths.
flowers or other items will no be permitted.
Once a tree is planted and/or a plaque is in position, it is intended that their location will
be permanent; however, if the City determines that the tree and/or plaque must be
removed or relocated, the City has the right to do so.
THIS "PARKS BEAUTIFICATION AND TREE PROGRAM" POLICY SUPERSEDES
ALL OTHER SIMILAR POLICIES PREVIOUSLY ESTABLISHED BY THE PARKS
AND RECREATION COMMISSION.
ALL OTHER REQUESTS FOR COMMEMORATION PURPOSES, SUCH AS
PLAQUES ON BUILDINGS, BENCHES, BRICKS, FLAG POLES, STATUES,
FOUNTAINS, AND MEMORIAL GARDENS, SHALL BE BROUGHT BEFORE THE
CITY OF PALM SPRINGS PARKS AND RECREATION COMMISSION ON AN
INDIVIDUAL BASIS, THE PARKS AND RECREATION COMMISSION SHALL
THEN MAKE ITS RECOMMENDATION TO THE CITY COUNCIL FOR ITS
APPROVAL OR DENIAL OF THESE PROJECTS ON AN ITEM -BY -ITEM BASIS.
