(See section 2.6 of State CEQA Guidelines. If more than Yes ❑ No ❑ N/A one project is present in the same area, cumulative impacts should be considered). ■ If "yes" above, does the project fall into any of the Emergency Projects listed in Section 15269 of the State °Yes ■ No ❑ N/A CEQA Guidelines? ■ If "no" in II, does the project fall under any of the Ministerial Acts listed in Section 15268(b) of the State °Yes ■ No ❑ N/A CEQA Guidelines? • If -no" on III, does the project fall under any of the Statutory Exemptions listed in Article 18 of the State ° Yes ■ No ❑ N/A CEQA Guidelines? If -no- on IV, does the project qualify for one of the Categorical Exemptions listed in Article 19 of the State °Yes ■ No ❑ N/A CEQA Guidelines? (Where there is reasonable probability that the activity will have a significant effect due to special circumstances, a categorical exemption does not apply). Based on the information provided above, the proposed action is a project, and would not be exempt from CEQA. 1.2 PURPOSE/USE OF THE INITIAL STUDY The purpose of this Initial Study (IS) is to describe the proposed "Crescendo' residential project, Case No. 5.0996-PD-294 (Tentative Tract Map 31766 and Preliminary Planned Development District #294) and provide a preliminary evaluation of potential environmental effects associated with the project's short term construction and ongoing use. The IS has been prepared pursuant to the California Environmental Quality Act (CEQA), as amended (Public Resources Code §21000 et seq.), and in accordance with the State CEQA Guidelines (California Code of Regulations §15000 et seq.). Pursuant to Section 15367 of the State CEQA Guidelines, the City of Palm Springs is the lead agency for the project. The lead agency is the public agency that has the principal September27 2004 Page 1 City of Palm Springs -Crescendo-(TTM 31766), Case No. 5-0996-PD-294 Initial Study responsibility for carrying out or approving a project that may have a significant effect upon the environment. The City of Palm Springs, as the lead agency, shall have the authority for project approval and certification of the accompanying environmental documentation. The City of Palm Springs is expected to use the information contained in this Initial Study during deliberations regarding implementation of the proposed project. CITY OF PALM SPRINGS The following actions will be considered with approval of the project. ■ Adoption of the Mitigated Negative Declaration - Prior to approval of the project, the City shall consider the Mitigated Negative Declaration (MND) together with any comments received during the public review process. The City shall adopt the MND only if it finds on the basis of the whole record before it that no substantial evidence exists supporting a fair argument that the project will have a significant effect on the environment and that the MND reflects the City's independent judgment and analysis. ■ Adoption of the Mitigation Monitorinq Program - Prior to approval of the project, the City shall adopt a Mitigation Monitoring Program pursuant to CEQA Guidelines Section 15097. ■ Zone Change - In order to provide zoning which conforms to the design reflected on Tentative Tract Map 31766 (including a minimum lot size of 15,000 square feet), a zone change application is required. The proposed project requires a change of the current zoning from R-1-A to PD No. 294 (Planned Development District). ■ Tentative Tract Map -The project applicant is requesting the approval of Tentative Tract Map No. 31766. ■ Preliminary Planned Development District No. 294 - The project applicant is requesting the approval of a Preliminary Planned Development District to implement the proposed PD zoning. ■ Right-of-Way Vacation - The project applicant is requesting the vacation of the westerly 23 feet of the Vista Grande Avenue right-of-way. Subsequent approvals by the City of Palm Springs may include: ■ Final Development Plan ■ Grading permits ■ Building permits September 27, 2004 Page 2 City of Palm Springs "Crescendo"Project(TTM 31766)Initial Study RESPONSIBLE AND TRUSTEE AGENCIES This IS/MND will also provide environmental information to responsible agencies and other public agencies that may be required to grant approvals in support of project implementation. These agencies include, but are not limited to, the following: • State of California, Regional Water Quality Control Board. Pursuant to the Federal Clean Water Act [Section 402(g)] and state General Construction Activity Storm Water Permit, a National Pollution Discharge Elimination System (NPDES) permit and storm water pollution prevention plan will be required from the California Regional Water Quality Control Board (RWQCB) for grading and construction in areas greater than five acres. Pursuant to the NPDES permit requirements, a Notice of Intent must be submitted to the State Water Resources Control Board. 1.3 SUMMARY OF FINDINGS Based on the environmental checklist form prepared for the project and supporting environmental analysis (provided in Section 4), the proposed project would have no impact or less than significant impacts in the following environmental impact areas: agricultural resources; biological resources, cultural resources, geology Et soils; hazards & hazardous materials; mineral resources; noise (long term impacts); hydrology/water quality; population/housing; public services; recreation; and transportation/traffic. The proposed project has the potential to have significant impacts related to aesthetics; air quality; land use/planning; noise (short-term construction-related impacts) and utility/service systems unless the recommended mitigation measures are incorporated into the project. According to the CEQA Guidelines, it is appropriate to prepare a mitigated negative declaration (MND) for the proposed project because, after incorporation of the recommended mitigation measures, all potentially significant environmental impacts would be eliminated or reduced to a level considered less than significant. 1.4 CONSISTENCY SUMMARY The project is consistent with the following plans: City of Palm Springs General Plan ■Yes ❑ No ❑ N/A Applicable Specific Plan ❑Yes ❑ No ■ N/A City of Palm Springs Zoning Ordinance ❑ Yes ■ No ❑ N/A South Coast Air Quality Management Plan ■Yes ❑ No ❑ N/A Airport Part 150 Noise Study ❑ Yes ❑ No ■ N/A Draft Section 14 Master Development Plan ❑ Yes ❑ No ■ N/A September 27, 2004 Page 3 City of Palm Springs Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study Note: The proposed project, if approved, will amend the Zoning Map whereby the "No- response would be changed to "Yes". 1.5 REQUIRED STUDIES The following studies have been required by the City of Palm Springs for this project, which are listed in Section 5, References. 1.

The mitigation program consists of three components: (a) self-mitigating design features of the project, (b) standard City Conditions of Approval or other mandatory regulations applied during the City's normal development review processes and, (c) if mitigation is required beyond the first two components, special mitigation measures intended to mitigate impacts to a less than significant level or reduce them to the maximum extent feasible. ■ Section 5- References. This section identifies those references used in preparation of the IS. September 27, 2004 Page 5 City of Palm Springs -Crescendo`(7TM 31766), Case No. 5-0996-PD-294 Initial Study SECTION 2 - LOCATION AND SETTING 2.1 PROJECT LOCATION The project site is located in the City of Palm Springs, Riverside County, California. It is bounded on the south by West Racquet Club Road and single family homes, on the east by Vista Grande Avenue and single family homes, on the north by Tram Way and vacant land, and on the west by vacant land within the Agua Caliente Band of Cahuilla Indian Reservation (Section 4)_ The regional location and local vicinity of the project site are depicted on Exhibits 1 and 2, respectively. West Racquet Club Road provides vehicular access to the project site. State Highway 111 and the Interstate 10 Freeway provide regional access to the area. 2.2 ENVIRONMENTAL SETTING The project site is located at the interface between existing urban development and native desert land. Three sides interface with a manmade environment (the Little Tuscany residential neighborhood and Tram Way) while the other interfaces with relatively undisturbed desert land (the Chino Cone). SITE SETTING - CHINO CONE The project site is located on undeveloped open desert land associated with the Chino Canyon alluvial cone (the Chino Cone or the Cone). As shown in Exhibit 3, the Chino Cone is a large alluvial feature that emanates from Chino Canyon at the base of the San Jacinto Mountains and spreads outward to the west onto the floor of the Coachella Valley. Alluvial fans are created over long periods of geologic time as waterborne sediments are eroded and conveyed from the mountains and deposited by gravity in a conical shape at lower elevations. Various manmade features are present on the Chino Cone. These include (a) Tram Way that provides access from State Highway 111 to the Palm Springs Aerial Tramway (located in Chino Canyon), (b) a U.S. Army Corps of Engineers levy that provides flood protection to the northern part of the City including a large portion of the Chino Cone, and (c) portions of the Little Tuscany Neighborhood, a hillside residential community lying south of Tram Way and extending from Highway 111 to the base of the San Jacinto Mountains, Tram Way serves as a general demarcation between the portions of the Cone that contain development and those that do not. The majority of the Cone lies north of Tram Way and is still undeveloped. In undeveloped areas, the native ground surface is characterized by loose cobbles and boulders and desert vegetation including cactus that exhibit blooms during the cooler parts of the year. The 350-acre "Shadowrock" project is also located north of Tram Way. This project, approved in the early 1990s, is proposed to contain an 18 hole golf course along with hotel, residential, and condominium units. Although the project has not been built, all entitlements are covered by a development agreement. Undeveloped lands are also present south of Tram Way. The majority of these are contained within the Agua Caliente Reservation (Section 4) but also include vacant lands proposed for development by the "Crescendo' and "Boulders" projects. Although occupying vacant desert land, each of these project sites extend partially or completely into the Little September 27, 2004 Page 6 YUCCA FOREST VALLEY FALLS OAK GLEN SAN BERNARDINO COUNTY .. .. .. .. .. ..

SITE SETTING - LITTLE TUSCANY The project site "notches" into the Little Tuscany neighborhood, adjoining lots and streets on the south and east. The Little Tuscany area is located on the Chino Cone with sloping land similar to the project site and is characterized mostly by one story, single family residences on uni-level building pads. Lots take access from double-loaded streets and tiers of lots are separated by intervening man-made slopes. A few homes have longer, steeper driveways and some use substantial retaining walls to create yard areas. Others exhibit true split level construction with "stepped foundations'. Neighborhood character is eclectic as lots were sold and homes constructed incrementally or in small groups by individual builders. SITE CHARACTERISTICS Onsite elevations vary between approximately 680 and 340 feet above mean sea level (msl) sloping from the west to the east. The ground surface of the property is characterized by cobbles and boulders with a soil matrix of silty sand and sand with silt. Some artificial fill created by adjacent road and utility construction is present along the edges of the site. Vegetation on the property consists of Sonoran creosote bush scrub. Existing site conditions are portrayed in Exhibits 4 and 5. Table 1 identifies the land uses surrounding the project site as well as the surrounding general plan and zoning designations.

The proposed project involves the following primary discretionary actions by the City, which are described below and evaluated in the attached Initial Study: Approval of Zone Change 5.0996 from R-1-A (Residential Low, 20,000 square foot minimum lot) to PD No. 294 (Planned Development District) Approval of Tentative Tract Map No. 31766 • Approval of Preliminary Planned Development District No. 294 • Vacation of a portion of Vista Grande Avenue ZONE CHANGE The project proposed by the applicant includes Change of Zone 5.0996. The Palm Springs Zoning Code designates the site as R-1-A (Residential Low, 20,000 square foot minimum lot). In order to provide zoning which conforms to the design reflected on Tentative Tract Map 31766 (to allow minimum lot sizes of 15,000 square feet, minimum interior lot width of 100 feet, minimum cul-de-sac and local street front setback of 10 feet, minimum corner lot side setback of 12 feet and minimum interior lot rear setback of 10 feet), a planned development district application is proposed. Per Section 94.03.00 of the City's zoning code, "The planned development district is designed to provide various types of land use which can be combined in compatible relationship with each other as part of a totally planned development. It is the intent of this district to insure compliance with the general plan and good zoning practices while allowing certain desirable departures from the strict provisions Of specific zone designations." in essence, the PD zone provides the City with extensive controls over all aspects of project planning and design, including architecture, as well as the ability to require amenities that would not otherwise be included in exchange for increased flexibility in meeting zone requirements. PRELIMINARY PLANNED DEVELOPMENT DISTRICT The project proposed by the applicant includes Preliminary Planned Development District No. 294 to implement the proposed PD zoning and illustrate building siting, architectural treatments and landscape architectural amenities for the project. As allowed by the PD District, the preliminary development plan proposes standards that deviate from the R-1-A Zone. In exchange, the PD zone provides the City with extensive controls over the project design, including architecture, as well as the ability to require the provision of amenities not otherwise included. Since the project design is consistent with the City's General Plan residential land use and density requirements as well as existing development in the vicinity of the project, use of the PD zone is allowed. Lot sizes proposed by the project range from 15,000 to 64,500 square feet and average 21,280 square feet. Lot widths range from 100 to 320 feet. A comparison of the project to the R-1-A zone standards is provided in Table 2.

City of Palm Springs "Crescendo"(77M 31766), Case No. 5-0996-PD-294 Initial Study TENTATIVE TRACT MAP The project proposed by the applicant includes Tentative Tract Map (TTM) 31766. The TTM identifies the configuration of 79 proposed single family lots on 42.2 acres, the building pad and proposed elevation of each lot, proposed open space lots, proposed infrastructure, the proposed internal street pattern and representative street sections. RIGHT-OF-WAY VACATION The project proposes to vacate the westerly 23-feet (currently unimproved) of the Vista Grande Avenue right-of-way. This would leave 37-feet of right-of-way, enough to contain the existing paved road improvements presently serving the area. 3.2 PROJECT DEVELOPMENT FEATURES The following discussion provides a description of the main components of the proposed project. The proposed development concept for the project is shown on Exhibit 6. RESIDENTIAL AND OPEN SPACE The proposed project includes 38.6 acres of residential development and 3.6 acres of private streets. Table 3 provides a statistical breakdown of the proposed land uses, as well as key development features. As shown on Table 3, the project would subdivide the project site into 79 single-family residential lots. Residential lot sizes range from 15,000 square feet to 54,500 square feet and average approximately 21,280 square feet. The project design locates larger lots and buffers (in the form of slopes and retention basins) around the project periphery with smaller lots generally interior to the project. The project is consistent with the overall general plan density of two units per gross acre for the L-2 designation.

In addition to building pads, lots contain (a) 6.3 acres of perimeter landscaping along Tram Way,W. Racquet Club and eastern property boundary (i.e. renaturalized slopes, retention basins and public walkway system) and (b) 4.3 acres of renaturalized manufactured slopes between lots and along the west property boundary. The project will also install landscaping within the ROW of West Racquet Club Drive and Tram Way that is not reflected in these acreages. --------------- September27, 2004 Page 15 •. �i r 7��riir. �1/4111r niimua Fail a � - �:�\i"-!'

Manufactured 2:1 or flatter (ratio of width to height) slopes and retaining walls (2-5 feet high) between the lots would allow the site to step down from the higher elevations on the west to the lower elevations on the east. The grading design would create an approximately 16 foot to 20 foot high fill slope outward facing at the eastern edge of the property that would be contour graded and renaturalized with desert landscaping and native boulders. Approximately 225,000 cubic yards of earthwork are proposed. Cut and fill would be balanced onsite and no import or export soil is proposed. Due to the large numbers of boulders on-site, rock crushing is proposed as part of site grading operations. As shown on Exhibit 8, the crushing plant would occupy an area of about 150 feet by 600 feet plus stockpile areas. The plant would be situated in the extreme northwestern corner of the project along Tram Way, approximately 800 feet from the nearest residence on the east and 1,000 feet from the nearest residence on the south. Crushing and grading operations would last between eight to nine and a half months and would be conducted during daytime hours in compliance with the City's Noise Ordinance. CIRCULATION SYSTEM Vehicular Circulation Regional access to the area is provided by State Highway 111/North Palm Canyon Drive (Major Thoroughfare on City General Plan), which enters Palm Springs from the North approximately one quarter mile east of the project site. Public roads providing local access to the site include West Racquet Club Drive (Secondary Thoroughfare on City General Plan) and Vista Grande Avenue (local street). Abutting the project's northern boundary is Tram Way (Major Thoroughfare on City General Plan), a semi-gated private road providing access to the Palm Springs Aerial Tramway. As shown on Exhibit 5, the proposed interior circulation system is designed as two separate, unconnected road systems, each with its own primary entry and a gated secondary emergency access. One road system serves the higher, westerly third of the site while the other serves the lower, easterly two thirds of the site. All interior streets will be privately maintained by the project Homeowners Association. Primary project access from each area is provided by an ungated entry located on West Racquet,Club Road (along the southern boundary of the project site). Because shopping, employment and other key destinations occur within central Palm Springs to the east, residential vehicle movements at these two entries will tend to be right turns into the project and left turns out. Two emergency access roads are also proposed, one connecting to Vista Grande Avenue and one to Tram Way. These entries would be permanently gated with a Knox Box for use by emergency vehicles only. Typical street sections are shown on Exhibit 9a and 9b. Pedestrian Access The project proposes pedestrian circulation for residents and the public via a looped system of walkways around and through the project. These walkways would parallel the rights-of- way for Tram Way Road and West Racquet Club Drive with north-south connections at the September27, 2004 Page is NOTE: y/`�� Legend A temporary barrier or non-continuous operation 6x�;� � � /�-, i_"`1 '' of the crushing plant will be implemented until adequate berm height has been achieved.

The walkway system would allow public access from neighborhoods south and east of the project to Tram Way, which has traditionally served as a hiking and jogging route for area residents and would allow for possible future connection to the Palm Springs Visitors center at Tram Way and Highway 111. Three rest stations with benches would be provided at intervals along the walkway. The walkway system is shown in Figure 10. The project will also construct connections to the walkway system from interior streets at numerous cul-de-sac bulbs and entries. No sidewalks are proposed along local streets in keeping with the character of surrounding neighborhoods. Instead, residents would utilize the interior private street system for pedestrian circulation within the project but could easily access the perimeter walkway system from any location within the project at the provided connections. INFRASTRUCTURE In addition to the circulation system discussed above, the proposed project includes the infrastructure needed for storm drainage, sewer, water, and utilities (electric, gas, phone, cable, etc.). Planned sewer, water and storm drain facilities are shown.on Exhibit 6. Sewer Sewer service will be provided by the City of Palm Springs. The project proposes 8-inch sewer lines within private streets to collect waste water from the homes on site. Public utility easements would be granted over sewer lines within the project to provide the City with access and maintenance rights over their lines. The project would then gravity flow to existing sewer lines in West Racquet Club Road and Vista Grande Avenue. As shown in Exhibit 7, offsite sewer improvements would include approximately 2,350 feet of new sewer line within West Racquet Club Drive extending from Girasol Avenue along the length of the project to the western property boundary. Water Water service would be provided by Desert Water (DW). The project proposes 8-inch water lines within private streets to deliver water to the homes on site. Public utility easements would be granted over water lines within the project to provide DW with access and maintenance rights over their lines. Water for the proposed project would be provided via connection to DW's Chino Reservoir located approximately 1,200 feet to the south. As shown in Exhibit 7, offsite improvements would include a water line extension within Milo Street along with enhancements to the booster station. Storm Drain Storm water from the project site would drain via surface flow in streets to catch basins where it would be conveyed via underground piping to a series of five retention basins that have been incorporated into the project design. Three basins are located adjacent to Tram Way along the northwest project boundary, a fourth is located adjacent to Vista "Grande Avenue along the northeast project boundary and a fifth is sited at the project's southeast corner. The depth of onsite retention basins would vary, up to fifteen feet and would be designed to handle storm water from a 100-year storm. In combination, these five basins would provide for storage capacity of about 4.7 acre/feet. In addition, the City's Sewer September 27, 2004 Page 22 City of Palm Springs -Crescendo"C17M 31766), Case No. 5-0996-PD-294 Initial study Master Plan shows that Master Storm Drain Line 2 is planned along the project's western boundary to serve properties to the west. The project contains a 25-foot wide drainage easement and a 12-foot wide construction easement along the western boundary, which were reserved for the purpose of constructing and maintaining this portion of the line. The Crescendo project proposes to realign the easement to coincide with the northernmost east- west street and construct this segment of the master storm drain line passing within the project, concurrent with its in-tract infrastructure. Should the City and/or the Riverside County Flood Control District (RCFCD) determine that the construction of Line 2 should be deferred to a future time, the existing easements across the property will remain of record and a covenant will be recorded against those lots within the development, which the City determines will be impacted by the future construction of Line 2 by others. Natural Gas Natural gas proposed to serve the project would be provided by Southern California Gas. Natural gas lines are adjacent to the property boundary along Vista Grande Avenue and at West Racquet Club and Janis Drive. Natural gas would be extended from these connection points to each lot via the interior street system. Dry Utilities Dry utility facilities proposed to serve the project would be provided by the utility service providers (Southern California Gas, Southern California Edison, General Telephone Company and Time-Warner Cable) in accordance with service application agreements to be obtained by the developer. Proposed utility facilities would be constructed underground. No additional offsite construction is required since electric, telephone and cable are available at the property boundary. LANDSCAPE CONCEPT/PERIMETER WALLS Landscape Concept The conceptual landscape plan is shown on Exhibit 10. The primary project entries would feature stone wall treatments with heavy timber accents, entry towers and water bowls set on stone plinths. Landscape materials at the entry would include the use of palms, agava, vines, and boulders. An extensive native landscape program, including desert plants and the reuse of native boulders would be employed along perimeter street frontages and on manufactured slopes to create a more natural appearing slope. The use of exotic plant materials would be specifically prohibited within 100 feet of natural desert areas along the project's western boundary. Major slopes would be landscaped with desert plant materials, trees and boulders. Native boulders would be collected during grading operations and reinstalled on man-made slopes and in landscape areas to replicate the look of the native terrain. Slopes lying within private lots would be maintained by the private property owner while those facing outward at the project periphery would be maintained by the HOA. Walls and fences would be constructed by the builder to assure architectural compatibility in design and materials. Landscape cross sections are shown in Exhibits 11 a and 11 b.

After meeting with adjacent homeowners, however, the applicant agreed to remove the entry gates on West Racquet Club Drive to allow public access to the project. In addition, the applicant also agreed to remove a proposed perimeter wall to integrate with surrounding neighborhoods. The project would continue to use a combination of six-foot-high, slump stone masonry wall and tubular steel view fencing around private yard areas. ARCHITECTURAL CONCEPT The architectural concept for the project proposes 79 one and two story single family residential buildings with a maximum height of about 20 feet for single story homes _ andabout 26 feet for two story homes. The second story elements proposed are relatively small, being limited to no more than 500 square feet. Only single story units would be placed on lots adjoining the eastern property boundary. Interior living and garage area on the ground floor would average about 3,400 square feet with covered patios, entry porticos, optional guest suites and optional second story elements providing additional indoor and outdoor living area. Three basic floor plans would be offered with a range of exterior elevations and options including larger garages, guest suites and second story living areas. 3.3 PROJECT CONSTRUCTION/PHASING It is expected that grading would begin in early 2005, and would last approximately eight to nine and a half months (preparing site for home construction). It is anticipated that the project developer would also be the home builder. Home construction would occur in five phases over approximately three years, subject to market conditions. The project site is sloping and would result in approximately 225,000 cubic yards of earth work to implement the tract design and related infrastructure. Rock crushing would allow use of boulder materials in manufactured fills such that cut and fill would be balanced onsite and there would be no need to import or export soil. Construction staging would occur onsite. 3.4 HOMEOWNERS ASSOCIATION A Homeowners Association (HOA) would be established for the project. It is anticipated that the following features of the project would be maintained by the HOA established under, and subject to, current state laws: private streets, retention basins and exterior facing slopes and landscaping. The City Attorney and Director of Planning Services will review the proposed HOA CC&Rs (covenants, codes, and restrictions) for adequacy and completeness. The CCBRs will outline the responsibilities of the HOA.

(Source 1) d) Create a new source of substantial light or glare ❑ ■ ❑ ❑ which would adversely affect day or nighttime views in the area? (Source 3) IMPACT ANALYSIS 1.a. Effect on Scenic Vistas POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. The City's general plan identifies all Major Thoroughfares as scenic corridors (Policy 5.24.7, see also section 9.b). The project site is located near North Palm Canyon Drive (Highway 111) and adjacent to Tram Way, both designated on the General Plan as Major Thoroughfares and, therefore, as Scenic Corridors within the City. Key relevant objectives and policies set forth in the General Plan regarding Scenic Corridors include the provision of landscape enhancements and the preservation of scenic vistas. The project does not lie adjacent to Highway 111 but does border Tram Way. Tram Way is a private semi-gated two lane paved roadway. The project will extend residential development up to Tram Way _ and originally included a slumpstone masonry wall at the right-of-way line along the length of Tram Way. The project did not propose any improvements within September 27 2004 Page 28 City of Palm Springs "Crescendo^(TTM 31766), Case No. 5-0996-PO-294 Initial Study the Tram Way right-of-way, but included the placement of three retention basins along Tram Way Road to provide increased building setbacks and allow mountain-view opportunities. After reviewing this design, the City determined that the project should be revised to incorporate a landscaped parkway with a minimum width of fifteen feet and an average width of twenty five feet along the length of Tram Way. The width of the parkway will meander and incorporate the detention basins so long as they are attractively landscaped with desert plants and are viewable from Tram Way. If safety fencing of the basins is required, an attractively designed view fence would be incorporated into the landscape design. In addition, homes placed near Tram Way will be oriented with random spacing, angled orientations and increased setbacks to avoid a regimented and uniform appearance. In addition to scenic vistas along major roadways, the City's General Plan also encourages the reasonable preservation of scenic views from adjoining properties (Policy 3.3.3, see also Section 9.b). The project's visual effect on adjacent properties is described as follows: EXISTING CONDITIONS IN ADJACENT NEIGHBORHOODS Southern Neighborhood An aerial view and photo index of the neighborhood to the south is shown in Exhibit 12a and photos of representative homes in Exhibits 12b and 12c. This neighborhood is located on sloping land similar to the project site and is characterized predominantly by one story, single family residences on uni-level building pads (see photos 1, 2 and 3). Lots take access from double-loaded streets and tiers of lots are separated by intervening man-made slopes. Homes with longer, steeper driveways are present (see photo 4) and some use substantial retaining walls to create a yard area (see photo 5). A few exhibit true split level construction with "stepped foundations" (see photo 6). Upward oriented mountain views to the east and downward oriented valley/city views to the southwest predominate in this neighborhood. The street pattern runs in a north-south direction and homes are generally designed with window placement to take advantage of city views to the southwest, away from the project site. As shown in photos 1, 2, 4, 6, and 7, uphill homes in this neighborhood tend to restrict mountain views (to a greater or lesser degree) from downhill homes. Neighborhood character is eclectic as lots were sold and homes constructed incrementally by individual builders. The project site lies north of this area and is separated by West Racquet Club Drive (88 foot wide right-of-way). Eastern Neighborhood An aerial view and photo index of the neighborhood to the east is shown in Exhibit 12a and photos of representative homes in Exhibits 12d and 12e.

City of Palm Springs "Crescendo"(77-M 31766), Case No. 5-0996-PD-294 Initial Study Exhibit 12f-View of Site from Adjacent Neighborhoods I I i :j I I i i i i 1 i i i i September 27, 2004 Page 35 i i City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 initial Study 1 and tiers of lots are separated by intervening man-made slopes, which becomes more pronounced in the western portions of the subdivision. The street pattern runs generally in a north-south direction and, as shown in photos 9, 10, 13 and 15. uphill homes in this neighborhood tend to restrict mountain views (to a greater or lesser degree) from the lower tier of existing homes. Neighborhood character is eclectic since lots were sold and homes constructed incrementally by individual builders. Upward oriented mountain views to the west predominate in this neighborhood. The project site lies immediately west and uphill from this area. Views of the project site from each adjacent neighborhood are shown in Exhibit i 12f, photos 16 and 17. VISUAL IMPACTS ON ADJACENT NEIGHBORHOODS Southern Neighborhood ".3 The project proposes building pads on the north side of West Racquet Club that are approximately at grade (within 5 feet) of existing residences on the south side of West Racquet Club Drive opposite the project. These homes are designed with window orientation to the southeast to take advantage of City views of Palm i Springs. Because the project does not lie between this neighborhood and either the mountains or the valley, the project would not interfere substantially with the primary views from this neighborhood. The project also employs a grading approach similar to that used in constructing this neighborhood consisting of uni- level building pads on double loaded, north-south oriented streets. Therefore, the project continues the development pattern already established in this neighborhood. Eastern Neighborhood i On the east, nine existing homes are sited nearest to the project. Four of these are located about 50-55 feet away from the project boundary across Vista Grande :1 Avenue with front yards facing the project. Five others are located about 5-1 O feet away from the project boundary and oriented with side or rear yards facing the project. Proposed building pads are approximately 16 to 20 feet above the elevation of these existing residences but are separated by an intervening slope a horizontal distance of 80 to 100 feet from the property line. The project design responds to this condition by placing a view fence at the top of slope, which will minimize view blockage beyond that created by the slope itself. In addition, the slope will be contour graded and re-naturalized with desert plants and boulders to recreate the appearance of a native desert slope. The effect of the slope will be similar to lots interior to the project, which will be sited adjacent to a re- naturalized landscaped slope of similar height. In addition to the slope itself, new residences atop the slope would have additional potential for view restriction. In response to this, the design places only seven residential lots along the western boundary. These lots are oversized with large setbacks and buildings are oriented with significant gaps in spacing so September27, 2004 Page 36 City of Palm Springs "Crescendo-(7TM 31766). Case No. 5-0996-PD-294 Initial Study that westward oriented mountain view op portunities (view corridors) are created between the buildings. Only single story residential structures will be allowed on the seven proposed homes nearest to the eastern property line. Despite these design features, implementation of any project on this site (including the proposed project) will alter views from the nearest existing lots facing the property that currently have an unimpaired uphill view of the mountains across the site. From these homes, distant views of the existing mountains would be replaced by near views of landscaped slopes, mid-range upward views of residential buildings and distant upward mountaintop views at gaps between and over, the proposed new homes. In considering this effect, it should be noted that the subject property is located uphill from these existing homes, that it lies between them and the mountains and that the City's General Plan calls for residential development on the project site. This combination will inevitably result in the restriction of mountain views from nearby homes to the east by this or some other project as presently occurs within the existing neighborhood itself. To illustrate this effect further, if the property were developed with homes at grade along Vista Grande Avenue, views from existing homes to the east would still be affected. Assuming lots that were 20,000 square feet in size and 120 feet wide, approximately twelve homes could be constructed along the western boundary. The existing ground slopes upward from the road and the building pad for a new home would likely be elevated 2-3 feet above the street at its nearest point with a split level foundation that could add another 3-4 feet at the rear of the house. These pad elevations combined with a 16-18 foot high building would result in structure heights that would range from 18-25 feet above the road, situated 20 to 25 feet from the property boundary and spaced about 20 feet apart (assuming 10 foot side yards). This alternative would have a greater visual effect on existing mountain views to the west but, in addition, would create a much less private and much more urban interface with existing residences. Rather than facing a slope with natural desert landscaping as proposed by the project, existing residences to the west would directly face the front or rear yards of twelve homes, 18-25 feet high, spaced uniformly along the property line. A comparative cross section analysis is shown in Figures 15 through 19. The cross sections represent views from existing homes to the east. Section locations are shown in Figure 13. Figures 14a-14d each provide two comparative cross sections, the first depicting the angle of mountain view restriction caused by the project and the second depicting a view restriction comparison with a hypothetical project alternative that eliminates the slope and replaces it with homes at grade backing or fronting the property line. The analysis indicates that, i in each instance, designing buildings at grade but closer to the property line would result in a somewhat greater restriction of mountain views than the project. In particular, Section A (Figure 14a) shows that an observer's view of the mountains would be blocked by the alternative project up to an angle of 13.3 degrees from horizontal while the project would only block views up to 8.5 degrees from horizontal. Section B (Figure 14b) shows that an observer's view of September 27, 2004 Page 37 %•, �X-A tea+;•^ Ns ljjj 1���. was i�O ��`'�`►��h���9�fi`s �� Q�.�7. 1111111111 ME Ill I l "`�w � a' � � ��� _• ��,pa obi a�-' ' �,�`����-�. =:�`���_ ��.°� �� _�_ ._1`r•v �Odp�r._ a�����y��NJie.�• v-op ({y�� c!��0 �:�:• 1+�, La--- ��• �'�- _.r -r--- 3irtir�v'�.���. • VIEWANGLES E oL1e�6�REEN'6A�ER MAINiEW,N6E ALOE65 n6`LAR SIELi.FEHGE SIGHTLINE 'A' ANGLE 8.6' EOADER6 SCENARIO ONE r a> R rREh SICHTLINE AT TOP OF SLOPE ( MOT IN vlm C RRIDOR) {jlll E%15TIN6 RF51p@L-E SIGHTLINE 'B' SCENARIO TWO ANGLE 133' .� Y .0 V 7Oa+ G TAIN6 AT SICHTLINE AT RESIDENCE I a EE _ ay E.3 T e A SCENARIO ONE(PROPOSED PROJECT) U STREET SECTIONAT'VISTA CRANDE AVE' ��`I' REE1veNOe -U'• � , �"`�_,,, _ ReArt LOAom eARAse C 4 — • ! 1� DRIVEngY SIbMLINE 9' _ 1 vIEY{iO MON.TAINe AT Y _ RESIOENGE ',A' M.VMAINS AT I us PAp 6R (AYERA6E MATION Ca.

Section C (Figure 14c) shows that an observer's view of the mountains would be blocked by the alternative project up to an angle of 19.1 degrees from horizontal while the project would only block views between 11.3 and 17.1 degrees from horizontal. Section D (Figure 14d) shows that an observer's view of the mountains would be blocked by the alternative project up to an angle of 21.8 degrees from horizontal while the project would only block views between 12.5 and 13.4 degrees from horizontal. In summary, the cross section analysis indicates that development of the property as proposed with homes built higher but set back further atop an intervening slope would result in a comparable or slightly reduced level of mountain view restriction as having homes built at grade with standard setbacks from the eastern property line. ' I For these reasons, the design proposed by the project, along with standard conditions and regulations, are considered a reasonable design response to views from neighboring residences and visual impacts on adjacent homes are considered mitigated by project design features to a level of less than significant. 1.b Damage to On-site Scenic Resources LESS THAN SIGNIFICANT IMPACT The project site is vacant and lies on the Chino Cone, a boulder strewn alluvial fan that slopes p generally from west to east. Distinctive physical features, including large, signature rock outcroppings or mature trees, are not present. The nearest State Scenic Highway, State Route 62, lies about 3.5 miles to the northwest and runs north from the Interstate 10 Freeway to the Riverside County line. Consequently, the project does not lie near a State Scenic Highway. On-site vegetation and soils are common to the Coachella Valley and the project is surrounded on three sides by manmade structures (residences and roadways). Consequently, while the project will entirely remove the existing desert landscape from the site, this landscape is not currently in a pristine location and is visually influenced by both the manmade environment (surrounding homes) as well as the natural environment (adjacent desert land). Since the project lies at the interface where the manmade and natural environments meet, it seeks to integrate them both in its design approach. To accomplish this, the project proposes the extensive use of native boulders and desert plant materials throughout the project, especially at key locations where the site is exposed to public view, including the streetscapes for Tram Way and West Racquet Club Drive as well as the manmade slope along the eastern property boundary. The project will use undulating terrain, variable slopes, contour grading, native boulders, and desert landscape materials at these key locations to provide a strong visual sense that the project is related to and blends with the surrounding desert landscape. September27, 2004 Page 43 I City of Palm Springs 'Crescendo-(7TM 31766), Case No. 5-0996-PO-294 Initial Study For these reasons, project implementation with the design features discussed above will result in less than significant impacts to on-site scenic resources and no additional mitigation is required. I 1.c Degrade Visual Character of the Site or Surroundings POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. As discussed under the previous topic, the project site is located on the Chino Cone at the interface between the manmade and natural environments. It would replace the existing native landscape containing desert vegetation, boulders and cactus with residential homes. Although the site contains native desert land, its visual character is .not pristine, being influenced on two sides by proximity to single family residences and on the third by Tram Way. Adjacent neighborhoods were built as un-walled, un-gated communities with public street access and individually designed homes constructed on uni-level foundations (see Exhibits 12a-12e). The project was originally proposed as a walled, gated community with private street access for residents only. In response to neighborhood requests, the applicant agreed to remove entry gates on West Racquet Club Drive and to eliminate a continuous perimeter wall in order to better integrate with the existing community character as perceived by surrounding residents. The project would introduce an upscale residential neighborhood characterized by a cohesive design theme and landscape enhancements along adjacent streets, at project entries and on exterior facing slopes. The project is required to submit a Final Planned ' Development that will ensure review of final architecture and landscape architecture at the construction level to ensure quality of architectural design and inclusion of desert plantings and boulders in landscaping. Offsite improvements include the installation of a new water line in Milo Drive. i Because this line would be installed underground within an existing street, the visual impact of offsite improvements would be negligible. Because the native landscape is already visually influenced by adjacent urban development and because the project will meet a high standard of architectural design and employs an extensive desert landscape theme, project implementation will not substantially degrade the visual character of the site or its surroundings and no additional mitigation is required. Also, see the discussion under preceding topics 1.a and 1.b. -� 1.d Create Substantial Light and Glare POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. The proposed project has the potential to create new sources of light and glare that could adversely affect adjacent residences and roadways as well as night sky visibility due to the operation of single family homes and street lights. Standard Conditions Et Regulations require on-site lighting to comply with applicable provisions of the zoning code, including limiting light and glare to avoid any spill over of light or glare onto surrounding properties or create a nuisance to vehicular i September 27 2004 Page 44 i City of Palm Springs -Crescendo-(TTM 31766), Case No. 5-0996-PD-294 Initial Study i traffic. The zoning code also requires directing light downward to reduce ambient light and maintain night sky visibility. Relevant General Plan policies include: Policy 4.4.e requires that hillside development use low lighting levels to avoid glare and to comply with Palomar Observatory night lighting requirements. Standard conditions requiring preparation of a lighting plan in compliance with the City's Outdoor Lighting Ordinance ensure that the project will achieve these j requirements. Therefore, the project is consistent with this policy. Policy 5.20.4 requires that street lighting be limited to that necessary for safety and that lighting intensity should be considered in relation to street classification, surrounding land uses and traffic volumes. Standard conditions requiring preparation of a lighting plan in compliance with the City's Outdoor Lighting Ordinance ensure that the project will achieve these requirements. Therefore, the project is consistent with this policy. For these reasons, project implementation will result in less than significant impacts due to light and glare and no mitigation is required. MITIGATION PROGRAM - AESTHETICS Project Design Features PD 1-1 The project includes landscaping enhancements within the project and along adjacent streets and slopes. PD 1-2 The project includes a coordinated community theme for architecture and landscape design. PD 1-3 The project includes open public entries and walls are limited to private yard areas, without a continuous perimeter wall to encourage integration and continuity with adjacent neighborhoods. i PD 1-4 The project incorporates view corridors as reflected on the Site Plan to maximize mountain view opportunities for existing homes along the eastern property boundary. The following techniques are employed to achieve view corridors: a. placing larger lots with increased setbacks along the eastern boundary; j b. allowing only seven lots to abut the eastern boundary with increased and varied separations between buildings; c. siting homes at oblique angles to the eastern boundary; d, placing tubular steel, wrought iron or similar view fences at the top of slopes along the eastern boundary; September 27, 2004 Page 45 City of Palm Springs 'Crescendo"(7TM 31766), Case No. 5-0996-PD-294 Initial Study fe. locating detention basins along the eastern boundary for increased open space and setbacks. PD 1-5 The project will re-naturalize the manufactured slopes created by the project (including the outward facing slope along the eastern property boundary) with native desert plantings and boulders to create slopes with a natural appearance as an attractive amenity for residents and neighboring homeowners. I PD 1-6 The project will incorporate contour grading (using variable slope gradients rather than a uniform 2:1 slope) along the outward facing slope at the eastern property boundary to replicate a more natural appearing slope face. Contour grading techniques will also be applied on interior slopes where practical. PD 1-7 The total number of residential lots on the project shall be reduced to 79 to allow increased buffers along the project perimeter and 100' minimum lot widths. i Standard Conditions £r Regulations SC 1-1 A Final Planned Development District (including architectural and landscape architectural plans) shall be submitted for review and approval by the Planning Commission. SC 1-2 An exterior lighting plan in accordance with Zoning Ordinance Section 93.21.00.

IMPACT ANALYSIS The following discussion is based on an Air Quality Analysis prepared for the project by Giroux and Associates dated June 14, 2004. The proposed project site is located in the Coachella Valley Planning Area of the Salton Sea Air Basin. The Coachella Valley is a desert region characterized by hot, dry summers and relatively mild winters. Rainfall is scant in all seasons with an average annual precipitation ranging from 2 to 6 inches per year. Seasonal average monthly temperatures range from 80OF to 108OF in July and from 40OF to 570F in January. National Ambient Air Quality Standards (AAQS) were originally established by the Federal Government in 1971 for six pollution categories with states retaining the option to add other pollutants, require more stringent compliance, or to include different exposure periods. These standards establish the levels of ambient air quality considered safe, including an adequate margin of safety, to protect the public health and welfare. Air basins where ambient air quality standards are exceeded are called "non-attainment" areas under the federal Clean Air Act. The Coachella Valley is considered a "nonattainment area" for ozone and particulate matter (PM-10) being further classified as a "severe' non-attainment area for ozone and a "serious" non-attainment area for PM10. The 1977 Amendments to the Federal Clean Air Act require that designated j agencies in any area of the nation not meeting national clean air standards must prepare a plan demonstrating the steps necessary to bring the area into compliance with all national standards. In 2003, such a plan was approved by the Federal Environmental Protection Agency (EPA) for the Coachella Valley. The 2003 valley-wide implementation plan sets various attainment dates to achieve federal standards including a deadline of 2006 for particulate matter and 2010 for ozone. Progress toward achieving State standards is required on a continuing basis with an attainment target of 2010 for all standards that have not been met before then. i September27, 2004 Page 49 i City of Palm Springs "Crescendo'(TTM 31766), Case No. 5-0996-PD-294 Initial Study 1, 3.a Conflict with or Obstruct Applicable Air Quality Plan LESS THAN SIGNIFICANT IMPACT. The 2003 Coachella Valley State Implementation Plan is the governing air quality plan in the project vicinity. Residential development, such as that proposed by the Crescendo project, does not directly relate to the air quality management plan in that the plan contains no specific air quality programs or regulations governing general or residential development. Therefore, the primary yardstick for determining whether or not a development is consistent with the air quality plan relates to its consistency with adopted population, housing, employment and land-use forecasts in use by the AQMD. Since City and County General Plans I serve as the basis for the air quality plan, a project which is consistent with the applicable General Plan land use and density/intensity standards would also be considered consistent with the Air Quality Plan. The project is also required to implement all feasible air quality mitigation measures identified in the "final EIR for the Palm Springs General Plan Update". For these reasons, project implementation is found to be consistent with local air quality plan and no additional mitigation is required. I 3.b Violate Air Quality Standard or Contribute to Air Quality Violation LESS THAN SIGNIFICANT IMPACT. i Long Term Operational Air Quality Impacts I Long term operational air quality impacts resulting from the project would be confined to vehicle emissions and daily use of household chemicals. The 79 unit project will create around 1,000 trips per day. The regional air emissions from project-related traffic are well below significance thresholds. The regional emissions were calculated using the California Air Resources Board 1 URBEMIS2002 computer model and the results shown in Table 4 below. Maximum daily emissions from project traffic, plus minor "area source" emissions such as personal care or cleaning products, paints, and solvents, natural gas combustion, etc., are no more than 25 percent of the significance threshold. For this reason, long term project emissions are considered less than significant. The air quality report prepared for the project concludes that the project's contribution to "regional emissions have been included in regional growth projections for the Coachella Valley, and are individually less-than-significant': Table 4 jProject-Related Long Term Operational Emissions (lb/day) •G :NOx C61 • On-Road Vehicles 10.8 12.1 135.5 0.1 10.4 "Area Sources' 4.4 1.1 1.5 0.1 0.0 TOTAL 15.2 13.2 137.0 0.2 10.4 Significance Threshold 75 100 550 150 150 Percent of Thresholds 20 13 25 <1 7 September 27,2004 Page 50 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study I i Short Term Construction Air Quality Impacts Short term air quality impacts would be attributable to site construction activities including the exhaust emissions from construction equipment and the generation of fugitive dust during site grading and rock crushing operations. Air quality modeling done for the project indicates that the maximum simultaneous project disturbance size will be 4.2 acres. Emissions of particulates (PM-10) from construction activity soil disturbance were evaluated using factors in the SCAQMD CEQA Handbook. Fugitive dust particulate matter is calculated as follows with the use of minimum dust control: PM-1 O = 4.2 acres X 26.4 pounds/acre/day = 110.9 pound/day Even with only minimum (once-daily watering) dust control and with maximum ..i daily simultaneous disturbance, the daily PM-10 significance threshold of 150 pounds per day will not be exceeded. However, the City of Palm Springs has adopted a fugitive dust ordinance that requires use of best available control measures (BACMs) for all construction projects. With mandatory use of BACMs, the accepted fugitive dust (PM-10) emissions factor is reduced from 26.4 to 10.0 pounds per acre per day (California Air Resources Board). Project-related construction activity PM-10 emissions, would therefore be reduced to 42 pounds per day as a worst-case condition, or 28 percent of the adopted significance threshold of 150 pounds per day. Crushing of rock represents an additional potential source of dust. However, the crusher and screens are equipped with water spray systems that control dust. At an estimated throughput of 4.000 tons/day, the SCAQMD estimates the following "extra" PM-10 emissions from crushing of oversize boulders. Project-Related Short Term Rock Crushing Emission sflb/clay) Material Transfer(2) 4,000 tons x 0.002 lb/ton 8 Ib/day i Cone Crushers/Screens 4,000 tons x 0.01 lb/ton 40-lb/day Jaw Crusher 4.000 tons x 0.605 Ib/ton 20 Ib/day i Total 68 lb/day i The combination of fugitive dust from site soil disturbance, (42 pounds/day) plus _, the crushing activity (68 pounds/day) will be 110 pounds per day, or still well below the 150 pounds per day significance threshold. i Exhaust emissions from typical construction equipment during site clearing and crushing (peak emissions generation activity) were calculated using accepted computer models. Emissions were calculated for an equipment "fleet" as follows: Off-Road Haul Trucks (2) Rubber-tired Dozer (1) September 27, 2004 Page 51 City of Palm Springs -Crescendo-(TTM31766), Case No. 5-0996-PD-294 Initial Study Rubber-tired Loaders (2) Water Truck i The computer modeling results for construction equipment emissions, plus the other PM-10 sources, are as follows: Table 6 Project-Related Short Term Construction Equipment Emissions(lb/day) Equipment Rock Fugitive • • Pollutant Exhaust Crushing Dust Total Threshold CO 77.9 - - 93.6 550 ROG 12.2 - - 12.2 75 NOx 92.2 - - 92.2 100 SOx 0.0 - - '<0.1 150 PM-10 4.5 68.0 42.0 114.5 150 As shown, all emissions are below the adopted significance threshold, however, the margin of safety between diesel exhaust NOx and the threshold is small. Reasonably available control measures for exhaust emissions reduction should therefore be implemented. As compared to crushing operations on site, if the boulders were hauled offsite for disposal and fill were imported from another location, onsite equipment exhaust emissions would be slightly reduced, but offsite trucking emissions would create a very large air pollution penalty. A calculation of local and regional air pollution generation was made using the computer model with results shown in Table 7. At 200 loads per day, 140 days of hauling rock and fill would exceed the daily NOx threshold (five work months). At a reduced level of trucking to maintain a less-than-significant NOx impact, it would require over 18 months of trucking activity. The trucking alternative is not recommended because there will either be a significant NOx exhaust impact, or the activity must be ongoing for 18 months at a reduced level if impacts are to be maintained at less-than- significant.

September27, 2004 Page 52 i City of Palm springs "Crescendo"(7TM 31766), Case No. 5-0996-PO-294 Initial Study In summary, a construction program to haul boulders Off-site versus crushing them on-site would result in significantly higher diesel exhaust NOx emissions and moderately higher levels of fugitive dust. Specifically. NOx emissions for hauling would .be 173 lb/day as compared to crushing, which would run off electric power and produces no on--site diesel exhaust emissions. The NOx from haul trucks alone (without considering on-site diesel earthmoving equipment) would exceed the NOx significance threshold of 100 lb/day. Staying below the NOx threshold would require fewer daily haul trips, thus extending the construction period to 18 months as compared to the 8-9 month period that could be accomplished with crushing gnificance threshold). Under a hauling scenario, fugitive dust t(PM-g1 O)ewou d below the generated jat borrow sites where replacement soil was obtained and at disposal sites where unusable boulders were taken. These activities are projected to result in 84 lb/day of PM-10 as compared to 68 lb/day for crushing activities. d Since short term construction and long term operational emissions for the project are below AQMD significance thresholds, and since the project is required to prepare a PM-10 Plan per Section 8.50 of the Palm Springs Municipal Code to reduce PM10 emissions, project implementation is determined to have a less than significant impact on air quality standards. I 3.c Cumulatively Increase Criteria Pollutant in Non Attainment Area LESS THAN SIGNIFICANT IMPACT. Since the 79 dwelling units proposed by the Crescendo project are consistent with the City General Plan land use and density, they represent an increment of growth that is planned by CVAG and the cumulative regional impact of project growth is considered to be less-than-significant. As discussed above, the project is also consistent with the AQMP and CVSIP. Air pollutants will be controlled to the maximum extent practical by adherence to the goals and policies contained in the Palm Springs General Plan along with mitigation measures described within this document. For these reasons, the Project's cumulative air quality impacts are considered less than significant. I 3.d Expose Sensitive Receptors to Pollutant Concentrations LESS THAN SIGNIFICANT IMPACT. The small number of residential units proposed by the project will not create high pollutant concentrations and there are no sensitive receptors in the vicinity of the project. Locally, the CO contribution of a maximum of 100 cars local roadwa per hour on any y is 0.2 ppm. The maximum background level in Palm Springs is 2 ppm. The most stringent one hour standard is 20 I worst-case local plus background CO levels of 2.2 ppm. The combination of ppm will be only 11 percent of the ambient standard. The air quality report concludes that, "the project is too small, and background levels are too "clean"to create any micro-scale air quality issues." For these reasons, project implementation will not have a significant effect on air quality at any sensitive land uses and no mitigation is required. 1 September27 2004 Page 53 City of Palm Springs t ; tYCrescendo"(77'M 37766), Case No. 5-0996-PD-294 Initial Study 3.e Create Objectionable Odors LESS THAN SIGNIFICANT IMPACT. The project proposes single family residential construction, which will cause no long term odors. Construction machiner y, equipment and/or vehicles may _ occasionally emit diesel exhaust odors that may be detectable by area residents under certain wind conditions. These odors are short term in nature, would result infrequently, if at all, and are a potential consequence of any construction on site in conformity with the General Plan. For these reasons, odors caused by project implementation are considered to be less than significant and no mitigation is required. MITIGATION PROGRAM —AIR QUALITY Project Design Features 1 There are no special design features related to air quality. Standard Conditions£r Regulations SC 3-1 Prior to the issuance of grading permits, a plan to control fugitive dust through implementation of best available control measures (BACMs) identified in the Coachella Valley Dust Control Handbook shall be prepared and submitted to the City of Palm Springs.

IMPACT ANALYSIS The following discussion is based on a Biological Assessment and Impact Analysis prepared for the project site by James W. Cornett Ecological Consultants dated December 11, 2003. Although field surveys were done at a time of year when most ephemeral plants would not be in evidence, the biological report concluded that officially listed or sensitive plant species were not expected to occur on the project site or in its immediate surroundings. This conclusion is based on the biologist's 30 years of experience in performing biological studies and field work in the Coachella Valley including similar nearby sites on the Chino Cone where exhaustive biological studies were completed (including the 350-acre Shadowrock project and the 160-acre Katrina Heinrich project) and no sensitive plant species were encountered. Additionally, there were no officially listed animal species that would not be present at this time of year. Therefore, the report provides the necessary information for determining if significant negative impacts would result from the development of the project. The Palm Springs General Plan identified the potential for sensitive animal species including the Desert Tortoise and the Palm Springs Ground Squirrel and for sensitive plant species including the Salton Milk Vetch (rare but no special status). These were not identified as present on site during biological surveys prepared for the project and discussed following. Existing Site Characterization ation -The project site slopes to the east and is covered with large rocks and boulders interspersed with pockets of coarse sand and gravel. Several small ravines traverse the site. No naturally occurring springs or Permanent aquatic habitats were present nor were any blue-line streams shown on the U.S. Geological Survey quadrangle maps. The site itself is relatively undisturbed by human activity although it is surrounded on three sides by severe human caused disturbances (residential homes and a paved roadway with moderate to heavy use). Existing Vegetative -h 'on - Sonoran creosote bush scrub was the single dominant plant community identified on the characteristic of this community found within the project site. Species creosote bush (Larrea tridentata) as the dominant boundary include the nial encelia (Encelia farinose), burrobush (Ambrosia dumosa)n and fdesert dlavende by r (Hyptis emoryi). Other common perennials included the sweetbush (Bebbia juncea), and white ratany (Krameria grayi). Existing Wildlife Characterization - Animals on the vicinity are characteristic of the Colorado Desert project site and surrounding f the Invertibrate species encountered on site included the nelo odes Sonoran armata), harvester ant (Pogonomyrmex californicus), painted lady butterfly (Vanessa cardui), and Southern California tarantula (APhonopelma eutylenum). September 27, 2004 Page 57 City of Palm Springs Crescendo'C177M 31766), Case No. 5-0996-PD-294 Initial Study Reptile species expected to occur on site included the ground gecko ((Coleonyx variegates), side-blotched lizard (Uta stansburiana), western whiptail (Cnemidorphorus tigris), chuckwalla (Sauromalus obesus), desert scaly lizard (Sceloporus magister), coachwhip (Masticophis flagellum), and the common kingsnake (Lampropelds getulus). Bird species observed on site include the rock a dove (Columba livia), mourning dove (Zenaida macroura), yellow-rumped warbler (Dendroica coronata), black-throated sparrow (Amphispiza bilineata), house finch (Carpodacus mexicanus), common raven (Corvus corax), and white crowned sparrow (Zonotrichia leucophrys). Mammal species detected on site included the California Ground squirrel (Spermophilus beeche)i), antelope ground squirrel (Ammospermophilus leucurus), desert cottontail (Sylvifagus auduboni), desert woodrat (Neotoma lepida), and coyote (Canis latrans). I 4.a Direct or Indirect Impacts on Candidate, Sensitive, or Special Status Species NO IMPACT i The biology report prepared for the project specifically evaluated the presence of any plant or animal species listed by the State or Federal government as rare, endangered or threatened along with any species being formally considered for listing. The project biologist consulted the primary inventories of California Rare, Threatened, Endangered and Special Status plants and only a single plant species that could conceivably occur on site was listed. This species was the California Ditaxis (Ditaxis serrata var. californica), which is considered a species of concern ' by the California Native Plant Society through it has no official state or federal status. It is said to occur between elevations of 400 to 3,000 feet within the Creosote Scrub Community in the vicinity of the San Jacinto Mountains in canyons and rocky hillsides. A concerted effort was made to locate this species during site surveys but no specimens were found. The project biologist consulted the California Department of Fish and Game's (CDFG) Special Animals list and identified two insect species known to occur in the Coachella Valley. They are the Coachella giant sand treader cricket (Macrobaenetes ua/gum) and the Coachella Valley Jerusalem cricket (Stenopelmatus cahuilaensis). The U.S. Fish and Wildlife Service (USFWS) has expressed concern over a third insect species, the Casey's June beetle (Dinacoma caseyi). None of these three species were found during site surveys. This probably reflects a lack of suitable habitat for the sand treader and Jerusalem j crickets since they are restricted to areas of loose, windblown sand-a habitat not found on or near the project. Casey's June beetle has only been encountered in the southern edge of the city, three miles to the south. In addition, the habitat for this species consists of sandy wash soils, not the coarse sand, gravel and boulders characteristic of soils found on the project site. None of these species are currently listed (or are considered as candidates for listing) as threatened or endangered by the CDFG or USFWS. i The project biologist consulted the primary inventories of State and Federal Endangered, Threatened and Special Status Animals and identified five animal i September27, 2004 Page 53 City of Palm Springs Crescendo-(TTM 31766), Case No. 5-0996-PD-294 initial Study i species that were known to occur in the region of the project site. They include the desert tortoise (Gopherus agassizi), burrowing owl (Speotyto cucniculana), loggerhead shrike (Lanus ludovicianus), Palm Springs ground squirrel (Spermophilus teredcaudus chlorus), and Palm Springs Pocket Mouse (perognathus longimembris bangsi). A concerted effort was also made to locate each of these species and none were found on site. Specific and formal protocol surveys do not exist for any of these species except the desert tortoise. Therefore, the USFWS tortoise survey protocol for field work was employed by i walking the site at 10-foot transect intervals. Although spring is the recommended protocol period for these surveys, evidence of presence (such as burrows) and not direct observation of animals is the most reliable method for determining the presence of the species. Since evidence of presence remains year round in the dry desert environment, field surveys are valid throughout the year. The failure to find any sign of tortoise during field surveys, coupled with the historic lack of tortoise in the immediate region during the biologist's 30-year experience in conducting tortoise surveys resulted in the conclusion that tortoises do not occur on, or immediately adjacent to, the project site. In summary, no sign of desert tortoise was found, no observation or evidence of burrowing owls was found, no loggerhead shrikes were observed, no ground squirrels or pocket mice were captured (although extensive trapping was conducted). It is noted, however, that the entire site is considered potential hunting and nesting habitat for the Loggerhead Shrike. However, because Creosote Scrub Habitat is prevalent throughout the southwest, the elimination of this area from Creosote Scrub Habitat is not expected to have a significant effect on the species. The report did not identify the on site presence of the Peninsular Bighorn Sheep (PBS), which occur in the adjacent San Jacinto Mountains. Typically, PBS are found on very i steep, rocky slopes that provide an opportunity to escape from predators. The project site is relatively flat and would be unsuitable as escape terrain. In the San Jacinto Mountains, sheep tend to stay at higher elevations between 3,500 msl to 4,300 msl, as compared to the 700+ msl elevations that characterize the project I site. The project is situated in a constrained location between Tram Way and residential development that eliminates any potential function as a movement corridor. It also contains no permanent water source or lambing habitat that would attract sheep. The site lies about a half mile from the toe of the San Jacinto Mountains adjacent, but outside, the Federally designated Critical Habitat boundary for the PBS. The report concludes that 'None of the plant or animal species found within the project boundaries are officially listed by any governmental agency` The report also concludes that, although 42 acres of creosote scrub habitat will be eliminated, '"the Creosote scrub habitat is widespread in the Southwest and therefore, the loss of this habitat on the project site cannot be said to constitute a significant negative impact to the continued existence of this plant community. For the reasons stated above, project implementation will not directly or indirectly affect any candidate, sensitive, or special status species and no mitigation is required. September 27, 2004 Page 59 I . l City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study i 4.b Impacts on Riparian Habitats or Sensitive Natural Communities NO IMPACT The project site contains only Sonoran Creosote Scrub Vegetative Community, which is widespread in the Southwest. No riparian or sensitive natural communities are present on site. For these reasons, project implementation will jhave no adverse effect on a riparian habitat or sensitive natural community and no mitigation is required. 4.c Impacts on Federally Protected Wetland NO IMPACT The project contains no naturally occurring springs or permanent aquatic habitats. No blue-line streams shown on the U.S. Geological Survey quadrangle maps cross the site: For these reasons, project implementation will have no adverse effect on any federally protected wetland and no mitigation is required. 4.d Impacts on Wildlife Movement, Wildlife Corridor or Nursery Site NO IMPACT. i The project site is surrounded on three sides by residential homes and a paved I roadway with moderate to heavy use. Because of this, the site could not function effectively as a corridor for animal movement nor is it suitable as a nursery site due to its proximity to human activities. For these reasons, project implementation will have no adverse effect on wildlife movement or nursery sites and no mitigation is required. 4.e Conflicts with Biological Protection Ordinance or Policy NO IMPACT. The City of Palm Springs General Plan is the primary document setting policies for the site regarding biological resource protection. The site lies outside the critical habitat for Peninsular Bighorn Sheep and lies outside any Conservation Area identified on the Draft Coachella Valley Multi-Species Habitat Conservation Plan (CVMSHCP). The area is not identified as being of special biological importance within the City General Plan. Relevant City policies include: Policy 5.5.8 requires the use of native landscaping materials adjacent to natural areas and prohibits the use of exotic plant materials within 100 feet of natural areas. The project complies with these requirements. i Policy 5.5.9 allows the City to require a biological survey of any project if it deems necessary. A biology report was prepared for this project. For these reasons, project implementation will not conflict with a biological protection ordinance or policy and no mitigation is required. September 27, 2004 Page 80 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study 4.f Conflicts with Habitat Conservation Plan NO IMPACT. j No Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP) covers the project site. The Coachella Valley Association of Governments (CVAG) is preparing a regional -Coachella Valley Multi-Species Habitat Conservation Plan" (CVMSHCP) that will encompass threatened, endangered, and sensitive species and their habitats. Although this plan has not been completed, it shows this site as lying outside of any CVMSHCP Conservation Area and therefore, the project site is not targeted for habitat preservation. The project does not lie within Agua Caliente Tribal lands and is therefore, not included within the Tribal Habitat Conservation Plan (Tribal HCP). Despite this, for consistency, the City applies Tribal HCP mitigations regarding Burrowing Owl surveys (see MM 4-1 below) on projects that may contain owls and abut Reservation lands. For these reasons, project implementation will not conflict with an approved habitat conservation plan and no mitigation is required. MITIGATION PROGRAM - BIOLOGICAL RESOURCES Project Design Features i PD 4-1 The project design proposes to use native plants and boulders to re- naturalize manufactured slopes within the project. Standard Conditions Et Regulations There are no standard conditions & regulations related to biological resources. Mitigation Measures MM 4-1 Prior to any ground or habitat disturbance on a site which provides burrowing owl habitat, the applicant shall cause a pre-construction survey of the site to be conducted for presence of the species. a. Surveys and relocation, if applicable, shall be conducted between September 1 and January 31, in accordance with the CDFG Staff j Report on Burrowing Owl Mitigation (1995) or other then-current protocols as directed by the City Director of Planning Services. b. Owls should be excluded from burrows in the development envelope and within an appropriate buffer zone by installing one- way doors in burrow entrances or other technique as deemed appropriate. The biological monitor must ensure through appropriate means (e.g. monitoring for owl use, excavating burrows) that the burrows to be impacted are not being used. The City shall determine whether creation of artificial burrows is necessary as part of the relocation effort.

Occupied burrows shall not be disturbed during the nesting season unless a qualified biologist verifies trough non-invasive methods that either: (a) the birds have not begun egg laying and incubation; or (b) that juveniles from the occupied burrows are foraging independently and capable of independent survival. ` MM 4-2 Prior to the issuance of building permits, the applicant shall submit an application for Final Landscape Document Package to the Director of Planning Services for review and approval. The landscape plan shall exclude the use of exotic plants within 100-feet of the abutting natural areas along the western project boundary. MM 4-3 Project CC&Rs shall require that landscaping along the project perimeter be maintained according to the approved Final Landscape Document Package.

(Source 5) i t IMPACT ANALYSIS The following discussion is based in part on a Historical/Archaeological Resources Survey Report prepared for the project site by CRM TECH dated January 16, September 27,2004 Page 62 City of Palm Springs -Crescendo-(7TM 31766), Case No. 5-0996-PD-294 Initial Study 2004. The report concludes that no evidence of significant cultural or archeological resources exist on site. A summary of the report follows: In December 2003 and January 2004. CRM TECH performed a cultural resources study on approximately 42 acres of vacant land in the City of Palm Springs, Riverside County, California. The property subject to study, Assessors Parcel No. 504-040-046, is located between Tram Way and Racquet Club Road, consisting of a portion of the northwest quarter of Section 3, T4S R4E, San Bernardino Base Meridian. The study was prepared as part of the environmental review process for the proposed development of the property as a residential tract, known as the -Crescendo" project, Tentative Tract No. 31766. The purpose of the study was to provide the City of Palm Springs with the necessary information and analysis to determine whether the proposed project would cause substantial adverse changes to any historical/ archaeological resources that may exist in or around the project area, as mandated by CEQA. In order to identify and evaluate such resources, CRM TECH conducted a historical/archaeological resources records search, pursued historical background iresearch, and carried out an intensive-level field survey. I During the field survey, an abandoned segment of riveted steel pipeline, which apparently, dates to the historic period, was recorded within the project area and 1 subsequently designated Site 33-13202 in the California Historical Resource Information System. The exact age and historical background of the pipeline j remain unclear, but the results of historical research and consultation with representatives of the various public water agencies and private water companies in the area suggest that it was probably installed in the 1920s as a part of the extensive water supply system for Palm Springs. As a minor, fragmentary, and ubiquitous element of historic-era infrastructure, Site 33- 13202 was determined not to meet the definition of a "historical resource," as provided in CEQA. i Based on the study results summarized above, CRM TECH concluded that no historical resources exist within the project area, and accordingly recommended a finding of No Impact regarding cultural resources. No further cultural resources investigation was deemed necessary for the proposed project unless development plans were expanded to include areas not covered by the study. It was recommended, however, that if buried cultural materials were encountered during construction activities, all work in that area should be halted or diverted until a .� qualified archaeologist could evaluate the nature and significance of the finds. 1 5.a Impact on Historical Resources NO IMPACT. A records search, research into local/regional historic mapping, oral interviews and an intensive ground field survey were performed to identify any historic and archaeological resources that might be present on the project site. The records search indicated that the project site had not been surveyed for cultural resources prior to this study and, although surveys on several nearby properties had been performed, none of them showed evidence of recorded archaeological sites that were near enough to be relevant to this project. The field survey study discovered September 27, 2004 Page 63 City of Palm Springs Crescendo'(TTM 31765), Case No. 6-0996-PD-294 Initial Study a 1,300 foot long segment Of riveted steel pipeline crossing the site, which may have been installed in the 1920's as part of Palm Springs'extensive water supply system. The pipeline was photographed and its location documented but it was jdetermined not to meet the definition of a "historical resource' as provided by CEOA. The term "historic resource' in CEOA refers to any resource listed in or determined to be eligible for listing in the California Register of Historical Resources, included in a local register of historical resources or determined to be historically significant by the Lead Agency. Historic maps indicate that, except for ;.� a few minor trails, no man-made features have ever been evident within the project site. No burial sites were identified from any literature, mapping or field survey. For these reasons, project implementation will have no adverse effect on i historic resources and no mitigation is required. 5_b Impact on Archaeological Resources NO IMPACT. .i As discussed in Topic 5.a, no archeological resources were found during record searches or field surveys of the site. Therefore, project implementation will have no adverse effect on archaeological resources and no mitigation is required. 5.c Impact on Unique Paleontological Resource or Geologic Feature j NO IMPACT. The property does not contain any unique geologic features and the General Plan EIR does not identify the site as containing any significant paleontological resources. For these reasons, project implementation will have no adverse effect on unique geologic features or paleontological resources and no mitigation is required. 6A Impact on Burial Sites NO IMPACT. As discussed in Topic 5.a, no burial sites were identified during record researches or field surveys of the site. Therefore, project implementation will have no adverse effect on burial sites and no mitigation is required I MITIGATION PROGRAM - CULTURAL RESOURCES Project Design Features There are no special project design features related to cultural resources. i Standard Conditions Er Regulations SC 5-1 Given that portions of the project area are within an alluvial formation, the possibility of buried resources is increased. A Native American Monitor shall be present during all ground-disturbing activities. t September 27, 2004 Page 64 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294/nitia/Study a. Experience has shown that there is always a possibility of buried cultural resources in a project area. Given that, a Native American Monitor(s) shall be present during all ground disturbing activities including clearing and grubbing, excavation, burial of utilities, planting of rooted plants, etc. Contact the, Aqua Caliente Band of Cahuilla Indian Cultural Office for additional information on the use and availability of Cultural Resource Monitors. Should buried cultural deposits be encountered, the Monitor shall contact the Director of Planning Services and after the consultation the Director shall have the authority to halt destructive construction and shall notify a Qualified Archaeologist to investigate and, if necessary, the Qualified Archaeologist shall prepare a treatment plan for submission to the State Historic Preservation Officer and Agua Caliente Cultural Resource Coordinator for approval. l b. Two copies of any cultural resource documentation generated in connection with this project, including reports of j investigations, record search results and site records/updates shall be forwarded to the Tribal Planning, Building, and Engineering Department and one copy to the City Planning Services Department prior to final inspection. Mitigation Measures After application of the Standard Conditions & Regulations listed above, no remaining significant impacts on cultural resources were identified and no additional mitigation is required.

I IMPACT ANALYSIS i The following discussion is based on a Geotechnical Engineering Report prepared for the project site by Earth Systems Southwest dated February 4, 2004. As part of this study, exploratory test pits were excavated to observe the soil profile and seismic refraction lines were performed to assess the excavation characteristics of the soil. The report concludes that the "site is suitable for the proposed development, provided the recommendations in this report are followed in design and construction': 6.a.i Exposure of People or Structures to Fault Rupture NO IMPACT. The project does not lie within a currently designated State of California Alquist- Priolo Earthquake Fault Zone. In addition, there is no evidence of faulting crossing the site from any other source. For these reasons, project implementation will result in less than significant impacts due to fault rupture and no mitigation is required. I i i I September 27 2004 Page 66 j City of Palm Springs 'Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study I j 6.a.i1 Exposure of People or Structures to Seismic Shaking LESS THAN SIGNIFICANT IMPACT. The nearest fault to the site is the South Banning Branch of the San Andreas ' Fault, located approximately 4.3 miles to the north. Various other active faults or seismic zones lie within 62 miles of the site. The project is located within Seismic Zone 4. Because of this, substantial ground shaking can be expected at the project as is common, to varying degrees, in most of Southern California. However, compliance with adopted building code standards for Seismic Zone 4 will reduce the effects of ground shaking on structures to acceptable levels. For these reasons, project implementation will result in less than significant impacts due to seismic shaking and no mitigation is required. 6.a.iii Exposure of People or Structures to Seismic Ground Failure (Liquefaction) LESS THAN SIGNIFICANT IMPACT. Liquefaction is the loss of soil strength from sudden shock (usually earthquake shaking) causing the soil to become a fluid mass. In general, for liquefaction to be imanifested at the surface, groundwater levels must be within 50 feet of the ground surface and the soils within the saturated zone must also be susceptible to liquefaction. The potential for liquefaction to occur at this site is negligible because the depth of groundwater beneath the site exceeds 100 feet. In addition, the project does not lie within the Riverside County liquefaction hazard zone. For these reasons, project implementation will result in less than significant impacts due to liquefaction and no mitigation is required. I 6.a.iv Exposure of People or Structures to Landslides iLESS THAN SIGNIFICANT IMPACT. The project site is located on a slope of about ten percent, according to the topographic mapping provided on the tentative tract map, which is not steep enough to result in landsliding beneath the project. Neither is the site near any steep slopes where landslides could occur from above. For these reasons, project j implementation will result in less than significant exposure to landslides and no j mitigation is required. 6.b Impacts due to Soil Erosion or Loss of Topsoil LESS THAN SIGNIFICANT IMPACT. Construction of the project has the potential to cause airborne and waterborne erosion during grading operations. These impacts are managed by standard protocols in place at the City during review of engineering design plans. The size of the project site will necessitate compliance with NPDES criteria, preparation of j a Storm Water Pollution Prevention Plan (SWPPP), and the inclusion of appropriate best management practices (BMPs) to control soil erosion and off-site discharge of surface water pollutants during construction and operation. The project will also be required to prepare a Fugitive Dust (PM10) Mitigation Plan in compliance with adopted procedures of the Air Quality Management District and the City of Palm Springs. Compliance with these procedures will ensure that i September27, 2004 Page 67 City of Palm Springs -Crescendo"(?-0'M 31766), Case No. 5-0998-PD-2941nitial Study potential erosion is controlled,during the construction process. Paving of streets and planting of landscaping will stabilize soils during the long term operational phase of the project (home occupancy). For these reasons, project implementation will not result in substantial soil erosion problems or the loss of top soil and no mitigation is required. 6.c Be Located in an Area with Unstable Soils NO IMPACT. � The geotechnical report prepared for the project evaluated the potential for landslide, liquefaction, and ground subsidence. In each case, it was determined that the potential for these effects was low at this location. Liquefaction potential is discussed in Section 6.I.iii. Landslide potential is discussed in Section 6.1.iv. Regarding ground subsidence, the geotechnical report states that dry sands tend to settle and densify when subjected to strong earth movement and, therefore, the potential for ground subsidence on site is low. Further, it should be noted that the project is located on similar soils and topography as adjacent residential neighborhoods that have not exhibited signs of unstable soils. For these reasons, project implementation will not create substantial risk to life or property due to unstable soils and no mitigation is required. 6.d Cause Substantial Risk to People or Property due to Expansive Soils NO IMPACT. The geotechnical report prepared for the project indicated that the soil matrix on site is visually classified to be in the very low expansion (E-1<20) category in accordance with Table 18A-1-B of the California (Uniform) Building Code. Consequently, project implementation will not create substantial risk to life or property due to expansive soils and no mitigation is required. 6.e Suitability for On-site Wastewater Disposal Systems NO IMPACT. The project proposes to dispose of wastewater by connection to the City sewer system. The use of on-site wastewater disposal systems is not proposed. For these reasons, project implementation will have no impact on the suitability of the site for onsite wastewater disposal systems and no mitigation is required.

(Source 10) IMPACT ANALYSIS 7.a Create Hazardous Condition by Transport or Disposal of Hazardous Material NO IMPACT. J Any hazardous materials on site (e.g. gasoline for lawnmowers, pesticides and weed killers, lawn fertilizers) would be for household use and would be purchased in small quantities at retail locations. State and Federal regulations govern the transport, storage and handling of these materials and the type of materials available for retail purchase. For these reasons, the project will create no i significant hazard related to the transport or disposal of hazardous materials and no mitigation is required. 7.b Create Hazardous Condition due to Upset or Release of Hazardous Material NO IMPACT. Residential uses do not inherently create hazardous conditions. Any hazardous materials on site (e.g. gasoline for lawnmowers, pesticides and weed killers, lawn fertilizers) would be for household use. The quantities kept in a residential setting would be too small to pose a hazard to the general public. For these reasons, the i project will create no significant hazard related to the use, upset or release of hazardous materials and no mitigation is required. I September 27 2004 Page 70 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PO-294 Initial Study Zc Create Hazardous Emissions in Proximity to School NO IMPACT. No existing or proposed schools occur within one-quarter mile of the project site and the emission or handling of acutely hazardous materials, substances or waste are not associated with daily residential activities. For these reasons, the project does not pose a hazard to nearby schools and no mitigation is required. _ 7.d Locate Project on Hazardous Materials Site NO IMPACT. There are no known hazardous materials on the property or in the vicinity of the site based on a Phase 1 Environmental Site Assessment conducted by the URS Corporation in 2001. The report concluded that: 1) the project site had been historically undeveloped desert land dating back to 1953; 2) the project site was not listed in the regulatory agency database; and 3) no sites in the vicinity were identified with the potential to create a recognized environmental condition on the project site. For these reasons, preexisting uses or activities do not pose a significant hazard to the public or the environment and no mitigation is required. 7.e Expose People to a Safety Hazard from a Public Airport NO IMPACT. The Palm Springs International Airport, located approximately two and one half miles to the southeast, is the nearest public/public use airport to the project site. The project is not within the airport influence area as identified in the current airport land use plan/master plan. For these reasons, the project would not j expose residents to safety hazards from public airport flights or operations and no mitigation is required. 7.f Expose People to a Safety Hazard from a Private Airstrip NO IMPACT. There are no private use airstrips in the vicinity of the project. For these reasons, the project would not expose residents to safety hazards from private airport flights or operations and no mitigation is required. 7.g Interfere with or Impair Emergency Response Plan NO IMPACT. The tentative map will be reviewed by the City Fire Department per standard City procedure to ensure consistency with emergency response and evacuation needs. Primary and secondary access routes have been incorporated into the project design to facilitate emergency response. For these reasons, the project would not impair or interfere with an emergency response plan and no additional mitigation is required. September 27, 2004 Page 71 City of Palm Springs -Crescendo'(1TM 31766), Case No. 5-0996-PD-294 Initial Study 7,h Expose People or Structures to Wildland Fire Hazard LESS THAN SIGNIFICANT IMPACT. The Palm Springs Fire Department considers the Chino Cane to be an area of high fire risk due to a history of wildland fires in the area of the cone. Therefore, the project would involve the construction of residences adjacent to an area with high fire potential. The Fire Department's ability to fight fires at the site is relatively good since the project lies adjacent to existing development, contains gentle _I slopes, and has readily available access. In addition, the project will improve fire i fighting capabilities by enhancing the area's fire flow (ref. Section 13a, 16) and improving access to the area by constructing West Racquet Club Road and interior paved streets. The project provides primary and secondary access to allow simultaneous evacuation of residents while emergency vehicles are entering. When completed, a portion of the project may lie outside the Fire Department's 5-minute response area (see Exhibit 15). Any structures which are determined to lie outside this area would require building sprinklers per Palm Springs Muncipal Code, Section 11.02.020. Development of the project in accordance with fire department requirements (hydrant locations, fire flow volume, fire resistant construction, primary and secondary access, vegetation management, etc.) would ensure that the potential hazard from wildland fires would be less than significant. MITIGATION PROGRAM - HAZARDS Et HAZARDOUS MATERIALS Project Design Features PD 7-1 The project provides primary and secondary access to each lot. i Standard Conditions Er Regulations SC 7-1 Prior to the issuance of building permits, the developer shall submit building plans for review and approval by the Palm Springs Fire Department that incorporate design techniques appropriate to high fire hazard areas, including any necessary building sprinklers in accordance with the requirements of Section 11.02.020 of the Municipal Code. Mitigation Measures After application of Project Design Features and Standard Conditions Er Regulations, no significant impacts due to hazards and hazardous materials were identified; therefore, no additional mitigation is required. i September27, 2004 Page 72 r---- gy 35 — 36 r 3"-rr rr. - if •.:�:--,......

I b) Substantially deplete groundwater supplies or ❑ ❑ ❑ interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g. the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)?

Case No. 5-0996-PD-294 Initial Study i) Expose people or structures to a significant risk ❑ ❑ of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? j) Cause inundation by seiche, tsunami, or mudflow? ❑ ❑ ❑ IMPACT ANALYSIS Specific topics regarding the exposure of people or structures to potential water related hazards, the project's effect on surface or subsurface hydrologic conditions, and the project's effect on water consumption and wastewater generation are discussed below: i 8.a.i Violation of Waste Discharge Requirement LESS THAN SIGNIFICANT IMPACT. The proposed project will connect to the City's sanitary sewer system, which would convey wastewater generated by the project to the Palm Springs Wastewater Treatment Plant. At the plant, wastewater is processed to a tertiary level of treatment. According to the City General Plan EIR, the wastewater treatment facility has a capacity of 10.9 million gallons per day (mgd) and currently processes an average daily flow of 8,6 mgd. Marcus Fuller, Senior Civil Engineer with the Palm Springs Public Works Department indicates that the proposed project densities (2 units per acre) were anticipated by the 1993 update to the City Sewer Master Plan and, therefore, no expansion of the treatment plant would be required to serve the project. The Regional Water Quality Control Board regulates the operation and any future expansion of the facility. Compliance with existing NPDES regulations and discharge requirements of the Regional Water Quality Control Board will ensure that potentially significant impacts will be reduced to less than significant. Based upon these facts the proposed project will not violate water quality standards or otherwise degrade water quality. For these reasons, project implementation would not violate any waste discharge requirement on a City. State, or Federal level and no mitigation is required. 8.a.ii Violation of Water Quality Requirement LESS THAN SIGNIFICANT IMPACT. The proposed project may result in surface runoff containing additional urban pollutants during its operation (during occupancy of the housing) due to an increase in impervious surfaces. The Preliminary Hydrology Analysis prepared for the site found that, with the provision of retention basins, there will be no incremental increase in storm water runoff when comparing the existing and developed conditions. The size of the project site requires compliance with September 27 2004 Page 75 City of Palm Springs Crescendo'(7TM 31766), Case No. 5-0996-PD-294 Initial Study i National Pollutant Discharge Elimination System (NPDES) requirements, including the preparation of a Storm Water Pollution Prevention Plan (SWPPP) utilizing appropriate best management practices (BMPs) to minimize surface water pollutants that might occur during both the construction and operational phases of the project. ! The use of BMPs are intended to reduce erosion and prevent pollutant run-off during .construction activities (such as grading and equipment maintenance) as well as controlling urban pollutants that accumulate over time on paved surfaces. Typical BMPs would include the use of sandbags around catch basins during construction to prevent eroded soils from entering the drainage system during rainfall, the inclusion of fossil filter systems in catch basins or water quality basins to capture first flush urban pollutants during long term residential operations. The City engineering department indicates that the basins included in the project design will serve this purpose. The Coachella Valley (a desert environment) normally experiences infrequent precipitation most of the year and the risk factor associated with rainfall is low. Site specific operational and procedural BMP packages tailored to the desert environment_arP�r uir_ed element of the SWPPP and will be developed for this project prior to site disturbance. For these reasons, project implementation would not violate any water quality standard on a City, State, or Federal level and no mitigation is required. 8.b Substantially Deplete Groundwater Supplies, or Reduce Aquifer Level or Volume LESS THAN SIGNIFICANT IMPACT. Project implementation would introduce additional impervious surfaces (pavement, rooftops) on the site and result in consumption of additional water supplies for residential use (drinking water and landscape irrigation). The General Plan estimates that a typical single family residence utilizes approximately 602 gallons per day (gpd) of water for all uses. Based upon this consumption factor, the proposed project would use approximately 47,558 gpd of water. This level of usage will not significantly affect the groundwater basin on a project level. Also, the site is only approximately 42.2 acres. and assuming 100% coverage of the site with impervious surfaces, the project would only cover a small fraction of the groundwater basin. There are no wells in the project vicinity and so the project would have no effect on local well levels. It should be noted, however, that the Whitewater River groundwater sub-basin is currently in an overdraft condition. Therefore, Desert Water (DW) would be contributing cumulatively to this overdraft condition by supplying water to any new project in the Coachella Valley, including this one. To address this situation and stabilize long-term ground water levels, DW has instituted ongoing programs including artificial recharge of the groundwater basin using State Water Project supplies and other surplus water, orderly expansion of the recycled water system and aggressive investment in and promotion of conservation programs. These programs (including water purchases) are funded by a groundwater assessment fee charged against groundwater well extractions. Due to its large size, basin September 27, 2004 Page 76 i City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study management is feasible with replenishment using surplus water during wet years and draw down during dry ones. When compared to the overall basin size and the large nearby areas permanently available for groundwater recharge (Whitewater wash), the project is not likely to affect groundwater recharge on a project level and may slightly increase "non- consumptive return" (irrigation) water. In addition, the inclusion of on-site stormwater basins would retain a portion of stormwater flows and allow increased percolation of these to the groundwater aquifer during storm events. Although this would occur infrequently due to the dry climatic conditions present, it would help offset the added runoff created by new impervious surfaces (rooftops and streets) built by the project. The project would follow water conservation guidelines included within the Palm Springs General Plan Update EIR (Page 5-100) and the Palm Springs General Plan (Pages 11-63 and II-64) and the Water Efficient Landscape Ordinance to mitigate the impacts to public water supplies. These would include the use of drought tolerant plants in landscaping. i For these reasons, project implementation would not substantially deplete groundwater supplies, interfere with groundwater recharge, or lower local groundwater table levels beyond that needed to support existing land uses on either a project or cumulative level and no mitigation is required. 8.c Substantial Drainage Alteration Resulting in Erosion or Siltation LESS THAN SIGNIFICANT IMPACT. The project will alter the entire site, including existing drainage conditions on-site, via grading operations to create streets and building pads. Therefore, erosion and siltation are potential impacts of the project. As discussed in Topic 8.a. above, compliance with mandatory NPDES requirements and BMPs will reduce the potential of erosion and siltation during short term construction and long term operational phases of the project. The final residential project will stabilize soils on-site through the use of landscaping and appropriate ground covers and control storm water via grading design, street drainage systems, catch basins and retention facilities. By protecting the soil and controlling storm water, soils on the site and downstream from the site will not be exposed to water borne erosion. For these reasons, although the project would alter the existing drainage pattern on site, self-mitigating features in the form of properly designed grading, street drainage, catch basins, storm drains and retention facilities (subject to review and approval by the City of Palm Springs under standard conditions of approval) have been incorporated into the project and no additional mitigation is required. 8.d Substantial Drainage Alteration Causing an Increase in Surface Runoff POTENTIALLY SIGNIFICANT IMPACT UNLESS MITIGATION INCORPORATED. The subject property is located on the southern portion of the Chino Canyon Alluvial Cone that drains to the Whitewater River Wash. Although upstream properties consist of undeveloped desert lands, only a relatively small, 4-acre, offsite drainage area flows onto the site. An existing system of small, localized, dry washes traverse the property. No rivers or streams occur on or near the site and no storm drain system exists in the project vicinity. September 27, 2004 Page 77 I i City of Palm Springs Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study A Preliminary HydrologyAnalysis, prepared by Hunsaker£r Associates Irvine, Inc., has been completed for the project site and found that retention basins could be adequately sized to handle the 100-year, 1 hour storm runoff produced from the project site. The project design addresses drainage concerns b 9 y incorporating five retention basins with a combined storage capacity of 4.7 acre/feet. In 1 accordance with City design regulations and State drainage laws, the basins would be designed to capture onsite flows and release them at predevelopment levels so that adjacent properties are not impacted by the concentration or diversion of flows. It is standard protocol for the City Public Works Department to ireview and approve all engineering design plans for street, storm drains and detention basins prior to recordation of a final subdivision map for the project. For these reasons, although the project would increase the rate or amount of surface runoff, mitigation in the form of properly designed retention facilities (subject to review and approval by the City of Palm Springs under standard engineering protocols) have been incorporated into the project. a 8.e Exceed Drainage System Capacity or Create Polluted Runoff LESS THAN SIGNIFICANT IMPACT. No permanent or intermittent streams or rivers occur within the project boundaries. The City has no local storm drain system accepting flows from this site and the incremental increase in site storm drainage from project implementation is being addressed through a system of retention basins as discussed in Topic 8.d. The potential for polluted runoff has been addressed by the project as discussed in Topic 8.a.ii. Therefore, by incorporating retention facilities and complying with mandatory regulations, the project will not exceed the capacity of an existing or planned storm drain system or generate additional sources of polluted runoff and no additional mitigation is required. 8.f Otherwise Degrade Water Quality LESS THAN SIGNIFICANT. As discussed under Topic 8.a.ii, impacts to water quality as a result of project implementation are considered less than significant and no additional mitigation is required. I 8.9 Place Housing within 100-Year FEMA Flood Hazard Area NO IMPACT. i JThe geology report prepared for the project indicates that the subject property is not within a Federal Emergency Management Agency (FEMA) 100 year flood plain (FIRM Panel 0602570004D - July 7, 1999). For these reasons, project implementation would not place housing within a 100-year FEMA flood plain and no mitigation is required. i I I September 27, 2004 Page 78 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-2941nitial Study 8,h Place Housing within 100-Year Flood Area that would Redirect Flood Flows NO IMPACT. The northern portion of Palm Springs, including this site, are protected from major flood flows by the Chino Cone levee to the north that directs storm flows from Chino Canyon to the Whitewater River Wash. The project site is elevated and is not within any other 100-year flood area. State drainage law requires that the project not increase or concentrate flows to downstream properties and the .I project includes detention facilities subject to standard City Engineering protocols to accomplish this as discussed previously under Topic 8d. For these reasons, project implementation would not place housing within any other 100-year flood plain that would impede or redirect flood flows and no mitigation is required. i 8.i Expose People or Structures to Flooding from Dam or Levee Failure NO IMPACT. 1 No dam or levee constraining a water body or watercourse exists upstream of the project site. For these reasons, project implementation would not place people/structures in the path of a flood due to structural failure of a dam or levee and no mitigation is required. 8.j Cause Inundation by Seiche, Tsunami, or Mudflow NO IMPACT. No large water body or reservoir exists upstream of the project and the project lies inland from the ocean. Therefore, conditions are not present that would pose a hazard from seiche, tsunami or mudflow to people or structures on site. Conversely, the project does not propose to construct any new reservoirs that would pose a risk of flooding or mudflow to any downstream properties in the event of a structural failure. For these reasons, project implementation would not expose people or structures to hazard from seiche, tsunami or mudflow and no mitigation is required.

The project site is bordered on the south and east by established residential neighborhoods. It is bordered on the north and west by vacant lands. Consequently, the project serves both to infill and to extend the residential uses around it. The existing single family neighborhood on the south and the neighborhood on the east are distinct and separate residential areas which are September 27 2004 Page 80 .j City of Palm Springs "Crescendo"'(TTM 31766), Case No, 5-0996-PD-294 Initial Study i divided by West Racquet Club Drive (a secondary thoroughfare on the City General Plan Circulation Map). The two existing neighborhoods share no interconnecting local streets and have been physically separated by the heretofore vacant lands within the project site. Construction of the project would infill between these established neighborhoods with a new neighborhood. iFurther, the project proposes a compatible residential land use among surrounding residential land uses of a similar intensity (i.e. 2 units per acre) and lot size (surrounding lot sizes range from about 10,000 to 20,000 square feet). The proposed project does not alter the physical arrangement bf either neighborhood or the circulation system serving them. The visual character of the proposed project and its relationship to the surrounding area is discussed under Topic 1.c. For these reasons, impacts associated with physical division of an existing community are considered to be less than significant and no mitigation is required. 9.b Land Use Regulation Conflicts LESS THAN SIGNIFICANT IMPACT. The proposed Project proposes,to subdivide 42.2 acres of vacant land into 79 single family residential lots with a minimum size of 15,000 square feet (averaging 21,250 square feet) and a minimum lot width of 100 feet. This would result in an overall density of approximately 1.9 units per gross acre. The project density is consistent with the City General Plan Land Use Element, which designates the site as L2 (Very Low Density Residential - one to two units per gross acre). The proposed minimum lot size and width, however, are not consistent with the current R-1-A zoning, which requires a minimum lot size of 20,000 square feet and lot width of 120 feet. In addition, the project also proposes various reduced setbacks (10' front yard, 12' corner side yard and 10' rear yard ). Approval of the proposed zone change to Planned Development (PD), however, would allow these modified standards and bring the project into conformity with the City's Zoning Ordinance, allowing similar lot sizes on the project site as those that exist in adjacent residential neighborhoods. In exchange for these modified standards, the Planned Development (PD) zone the provides the City with extensive controls over the project design, including architecture, as well as the ability to require the provision of amenities, such as the project's public walkway system, not otherwise included. i PLANNED DEVELOPMENT GUIDELINES It should be noted that various design guidelines are applicable to projects proposed under the PD zone (Municipal Code Section 94.03.00). These include: 1) that density does not exceed the General Plan maximum; 2) that the project is compatible with surrounding land use; 3) that the proposed use is permitted by the underlying zone; 4) that building heights comply with the underlying zone; 5) that parking requirements of the Zoning Ordinance are met; 6) that lot frontage and setbacks are consistent with surrounding development; 7) and that open space (including drainage facilities and other manmade structures) equal to that required in the underlying zone be integrated into the project and, where i integrated, that it seek to protect natural landscape features (watercourses, September 27, 2004 Page 81 City of Palm Springs -Crescendo"(7TM 31766), Case No. 5-0996-PO-294 Initial Study hillsides, sensitive land area, existing vegetation, wildlife, unique topographic features, views). The project complies with these guidelines as follows: 1) the project density of 2 units per acre is allowed by the General Plan; 2) surrounding residential lot sizes under R-1-A zoning, R-1-B zoning (south) and R-1-C zoning (east) range from about 10,000 and 20,000 square feet, which are consistent with those proposed by the project that range from 15,000 to 54.500 square feet; 3) residential uses are allowed in the R-1-A zone and such are proposed by the project; 4) the j underlying R-1-A zone allows building heights of one story with a maximum height of 18 feet or up to 30 feet in hillside areas if approved by the Planning Commission while the project proposes a combination of one and two story homes with a maximum height of 24 feet, requiring Planning Commission approval; 5) two spaces per single family residential unit are required by the Municipal Code (93.06.00.D.29.a) and the project provides two covered garage spaces per unit; 6) lot frontage and front setbacks on surrounding lots are approximately 100 feet and 25 feet respectively, which are comparable to those proposed by the project; and 7) the R-1-A zone has no specific open space requirement and therefore, it is assumed that compliance with the required yard area and building coverage requirements constitutes the necessary provision of open space (see calculation under General Plan Land Use Policy 3.4.6 below). In J addition, the project incorporates walkway and trail connections and passive recreation areas for public use. It also situates open space at the project perimeter to provide mountain view corridors for adjacent residences and incorporates native boulders and landscape to renaturalize man-made slopes and recreate native landscape scenes along perimeter roads where exposed to public View. CITYWIDE GENERAL PLAN GOALS Et POLICIES Overall goals in the Palm Springs General Plan Land Use Element focus on creating a physical environment which provides for the housing, employment, business, service, recreational, social, cultural, educational and entertainment needs of the City's residents and visitors while preserving the City's unique �. assets and status as a major tourist destination and business, economic and cultural center in the Coachella Valley. Policies developed in accordance with these goals pertaining to the proposed project include the following: I Policy 3.1.3 limits development, in terms of total numbers of dwelling units and ancillary uses, to the capacity of the infrastructure needed to support the Citys residents and visitors safely at a maximum capacity. The proposed project would not exceed the current capacity of the City's existing infrastructure. This issue is addressed in greater detail under Item 12. Utilities and Service Systems. Policy 3.1.7 directs that projects respect the integrity of the district or neighborhood in which they are planned. The proposed project, a low-density residential development, is consistent with surrounding low density residential land uses. In addition, the project would create subdivided lots that are generally larger than those adjacent to the project as well as the majority of those that are ' September 27, 2004 Page 82 CityOf Spring, Palm "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study in the immediate vicinity of the project. By way of illustration, the nine proposed lots that would be constructed along the project's south boundary (on the north side of West Racquet Club Drive) average 23,490 square feet as compared to the eight existing lots on the south side of West Racquet Club Drive that average only about 14,950 square feet. Likewise, the seven proposed lots within the project's east boundary average 40,380 square feet, as compared to the twelve existing lots along the project's east boundary that average only about 11,400 square feet. Therefore, the project has respected the lot sizes of adjacent properties by providing much larger lots along the project edges. In addition, the project proposes a linear street pattern with double loaded building pads, continuing the grading approach and street pattern present in adjacent subdivisions to the south and west. Consequently, the project is consistent with this policy. Policy 3.2.1 encourages infilling within the currently developed portions of the City. The proposed project is consistent with this policy as it is situated adjacent to existing residential development requiring minimal extension of City infrastructure and services. i Policy 3.3 3 encourages the reasonable preservation of scenic viewsheds from adjoining properties. The proposed project would construct a 16-20 foot high i renaturalized fill slope opposite existing homes across Vista Grande Avenue to the east. Distant views of the existing mountains would be replaced by near views of landscaped slopes, mid-range upward views of residential buildings and distant upward mountaintop views at gaps between and sometimes over, the proposed new homes. It should be noted that any development on the project site would obstruct mountain views to a greater or lesser degree because the site lies uphill from these homes. This effect is present within existing neighborhoods to the south and west (see Exhibits 12a and 12c). Cross section analysis presented in Section 1, Aesthetics, indicates that alternative approaches to grading design that reduce fill height would also move homes closer to existing residences on the east and potentially cause a greater degree of view restriction than the proposed project. Because the effect of the project on viewsheds is commensurate with any other residential project on this site due to its uphill nature, the project design is considered to effect a reasonable preservation of viewsheds from adjoining properties. Policy 3.3.4 allows densitytransfer in Planned Developments with P provision of amenities and permanent open space. The project provides a substantial public trail/open space/passive recreation system around and through the project and i situates larger lots at the project perimeter. At 79 lots, the project is below the General Plan density and, in this case, density transfer relates primarily to the shifting of density to the interior of the project where lot sizes are smaller and away from lots along the edges of the project where lot sizes are larger. This hierarchy of lot size benefits surrounding neighborhoods by placing the largest lots opposite them. Portions of larger lots containing slopes, retention basins and recreation areas would be retained in a permanent easement. Therefore, the project is consistent with this policy. September 27, 2004 Page 83 I City of Palm Springs Crescendo"(7TM 31766) Case No. 5-0996-PD-294 initial Study Policy 5 12 1 encourages new development to be designed to fit the natural landscape with a minimum of onsite grading. The project responds to the sloping natural terrain on site with a series of stepped building pads separated by manufactured slopes. It proposes the grading needed to create double loaded streets with building pads on each side while maintaining a grading balance on site. Other methods of building construction (i.e. double loaded streets with multi-level buildings on each side using stepped foundations or single loaded streets) could be used to possibly reduce on-site grading and cause a -better fit- between buildings and the natural landscape, however, either of these would require a major redesign of the project. Since this policy does not mandate any particular design solution and since the project does -step- with the natural terrain, it is deemed to comply with this policy. GENERAL PI.AN L-2 POLICIES Other policies relate specifically to the Very Low Density Residential (L-2) Land Use Designation. Since the project is designated L-2, these policies apply and are discussed as follows: i Policy 3.4.1 encourages single family homes as the predominant development type in the Very Low Density Residential designation. " The proposed project j consists only of single family residences on individual lots. i Policy 3.4 3 limits, new building heights to 26 feet. The policy provides performance criteria for increased heights up to 30 feet but states that uni-level pads are not eligible for the increased height. Buildings proposed by the project are 26-feet high on uni-level pads and so, are in compliance with this policy. I Policy 3.4.5 requires a minimum of 70% of the lot in Very Low Density Residential areas to be maintained as on-site open space/recreation area. For single family residences, this policy is equivalent to a 30% building coverage over the entire site. The project proposes three building products, the largest of which is 3,270 square feet. Taking a worst case analysis and assuming that the largest" footprint was placed on all lots, the coverage of all 79 buildings would be 258,330 square feet. By dividing this total coverage by the gross area of the site (42.2 acres or 1,838,232 square feet), an overall building coverage of 14.0% would result. Adding streets, which contain 3.6 acres (156,816 square feet) to the coverage calculation, coverage of buildings and streets would total about 9.5 acres (415.148 square feet) or 22.6% coverage. Thus, the project is consistent with this policy. For these reasons, the project is consistent with the City General Plan Land Use Designation and, with approval of the zone change, will be consistent with the City's Zoning Code. The project is also consistent with General Plan policy. For these reasons, the project complies with applicable land use policy and regulation. I September 27, 2004 Page 84 City of Palm Springs "Crescendo"(TTM 31766). Case NO. 5-0996-PD-294 Initial Study j NO IMPACT. No Habitat Conservation Plan (HCP) or Natural Community Conservation Plan (NCCP) covers the project site. The Coachella Valley Association of Governments (CVAG) is preparing a regional -Coachella Valley Multi-Species Habitat Conservation Plan- (CVMSHCP) that will encompass threatened, endangered, and sensitive species and their habitats. The draft CVMSHCP shows this site as lying outside of any CVMSHCP Conservation Area and therefore, the project site is not targeted for habitat' preservation. For these reasons, project j implementation will not conflict with an approved habitat conservation plan and no mitigation is required.

According to the California Department of Conservation, Division of Mines and Geology, three basic designations are used to classify mineral lands. These designations, or Mineral Resource Zones (MRZ's), are generally classified based on the suitability of hand and gravel deposits for use as Portland Cement Concrete (PCC) aggregate, and other geological. factors. •The three mineral resource classifications include: MRZ-1: areas where adequate information indicates that no significant aggregate deposits are present or where it is judged that little likelihood exists for their presence. MRZ-2: areas where adequate information exists to prove that significant mineral deposits are present or where it is judged that a high.likelihood for their presence exists. These, deposits must be marketable under present technologic and economic conditions or which can be estimated ,to exist.in.the.foreseeable-future, and that contain in excess of $6 million worth of aggregate material measured in 1978 dollars. MRZ-3: areas containing aggregate mineral deposits, the significance (i.e., quantity, quality, and marketability) of which cannot be evaluated from available data. The proposed project site is within a large area designated as MRZ-3 that includes the entire urbanized City of Palm Springs. A large MRZ-2 Zone also exists in the area north of the City that includes lands that are available for potential future mineral extraction (wind farms, wash areas.) The feasibility of commercial mining activity on the project site is minimal since: a) the value of the resources has not been demonstrated; b) mining would create long term conflicts with surrounding residential uses; and c) there are known accessible mineral resources available at more appropriate locations in the MRZ-2 zone to the north. For the reasons stated above, no significant impacts to mineral resources of regional or statewide importance will result from project implementation and no Mitigation is required. 10.b Impact a Known Mineral Resource Designated on a General or Specific Plan NO IMPACT, The site has not been designated on the City's General Plan or any Specific Plan or other Land Use Plan as a mineral resource site. Therefore, no significant impacts to mineral resources of local importance will result from project implementation and no mitigation is required.

September 27, 2004 Page 87 City of Palm Springs "Crescendo^'(TTM 31766), Case No. 5-0996-PD-294 Initial Study IMPACT ANALYSIS 11.a Noise Exceeding Established Ordinance POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. The following discussion is based on a Noise Impact Analysis prepared for the project by Giroux and Associates dated June 15, 2004. On a long term operational basis, the residential uses proposed by the project will not increase noise levels or expose people to high noise levels. The project lies outside the 60 CNEL contour for Highway 111 as shown in the General Plan EIR. Construction noise is not regulated by City policy, other than hours of operation. The City of Palm Springs has adopted numerous noise policies designed to achieve the City's noise objectives. The following noise policies set forth in the Noise Element of the General Plan could be relevant to the proposed project. Policy 6.20.1 directs that noise-sensitive land uses such as residences, hospitals and convalescent homes be protected from unacceptable noise levels from both existing and future noise sources. The proposed project does not involve any unusual noise levels and would generate long term operational noise levels that are comparable to those found in surrounding neighborhoods. i Policy 6.20.6 directs that project design include measures which assure adequate interior noise levels as required by Title 25 (California Noise Insulation Standards). The proposed project will be required to comply with these standards as part of building permit approvals. Policy 6.21.40 directs that new development minimize the noise impacts of traffic trips on residential neighborhoods by controlling the location of driveways and parking. The proposed project directs all traffic onto West Racquet Club Road, a Secondary Thoroughfare on the General Plan Circulation Exhibit. Policy 6.24.1 requires that construction activities which may impact adjacent residential units be limited to 7 a.m. to 7 p.m. during weekdays and Saturdays, =s except under special circumstances approved by the City, and prohibited on Sundays and holidays. The proposed project will comply with all City noise regulations including hours of operation for construction activities. Policy 6.24 2 requires that construction activities incorporate feasible and practical techniques which minimize the noise impacts on adjacent uses. The proposed project will locate rock crushing operations at the extreme western limits of the project, approximately 800-1,000 feet away from existing residences. The construction program for the project will also require construction of a berm adjacent to the rock crushing plant of sufficient height to maintain a maximum noise level of 53 dB (L50) at existing neighborhoods to the south and east. This is described in greater detail below. For these reasons, project implementation will not result in the generation of noise levels that exceed City standards and no mitigation is required. September 27, 2004 Page 88 City of Palm Springs 'Crescendo"fTTM 31766J, Case No, 5-0996-PD-294 Initial Study 1 1.b Ground-borne Noise or Vibration Impacts POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. Residential uses do not cause long term vibrations. Some temporary groundborne vibration is possible due to rock crushing activities during project grading operations. The project proposes to locate the rock crusher at the extreme northwest corner of the project 800-1,000 feet away from existing residences. Hours of operation for construction equipment are restricted to weekday working hours by the City's noise ordinance (Municipal Code Section 8.04.220). For these reasons, temporary increases in ambient noise during project construction are considered less than significant and no mitigation is required. 1 1.c Permanent increases in Ambient Noise Level LESS THAN SIGNIFICANT IMPACT. The project will result in permanent noise increases associated with residential development. Because the existing area is residential in character, new noise levels will not be excessive and will be consistent with ambient levels in the surrounding residential communities. The project will generate fewer than 1,000 trips per day on low-volume roadways. The noise level from 1,000 cars per day at 35 mph is less than 55 dB CNEL at 50 feet from the centerline. The City of Palm Springs standards for automobile-generated noise is 65 dB CNEL (requiring 10,000 cars per day for 35 mph traffic to have a significant impact). For these reasons, permanent project-related traffic noise and increases in ambient noise levels are considered less than significant and no mitigation is required. 1 1.d Temporary increases in Ambient Noise Level POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. Construction noise represents a short term, temporary impact on ambient noise levels. Noise generated by construction equipment, including rock crushers, graders, trucks, bulldozers, concrete mixers, and portable electrical generators can reach high levels. Grading activities typically represent one of the highest potential sources for noise impact. Delivery by truck of lumber, concrete and building materials represent another source of noise. One of the most effective and commonly used methods of controlling construction noise is through local regulation of construction to normal weekday working hours. In this regard, the project is required to comply with Section 8.04.220 of the Palm Springs Municipal Code that controls construction hours of operation. This would include both construction onsite and construction of offsite water and sewer lines in existing residential streets (West Racquet Club Drive and Milo Street). One unique aspect of site construction is the need to process or remove a large number of boulders, estimated to be 50-75% of the total soil volume. To address this, the project proposes to use one or two rock crushing plants to process boulders to a suitable size for use in on-site fills. The proposed rock crusher would operate at one location continuously for many hours per day and would be an ongoing noise source during the construction period. September 27, 2004 Page 89 City of Palm Springs -Crescendo'(TTM 31766), Case No. 5-o996-PO-294 Initial Study Although construction noise levels are not regulated by.City Ordinance, the Noise Analysis treated noise from the crushing plant as though it were regulated and arrived at a standard of 53 dB to be used as the acceptable noise level from the crushing plant at surrounding residential neighborhoods. In order to maintain this noise threshold at the adjacent residential neighborhoods, noise measurements taken at identical "hard rock' crushing plants in Southern California were evaluated to determine how quickly plant noise dissipates over distance. Based on this evaluation, it was established that the 53 dB threshold would be exceeded at the nearest residences if no mitigation were applied. In particular, noise levels at Vista Grande Avenue, some 800 feet away, were estimated between 60 dB and 66 dB while noise levels at Racquet Club Drive, some 1,000 feet away, were estimated between 57 dB and 64 dB. In order to mitigate crushing plant noise, the project proposes to construct berms of crushed rock to deflect noise originating at the crushing plant and reduce it to the 53 dB standard. The study determined that berm heights between fifteen and twenty feet on the east and between twelve and seventeen feet on the south would be necessary in order to achieve a noise level of 53 dB at the nearest residences on the south and east. The berms would be left in place for the duration of the crushing operations. This mitigation will be applied to the construction operations on site. i The alternative to crushing would be to haul the boulders away for disposal at another site and to import suitable replacement fill material. It is estimated that 28,185 truckloads of export and 17,300 truckloads of import would be required to accomplish this over a duration of about 13 months. The off-site dust, air pollution, traffic and noise generated by this type of truck hauling operation would have a greater negative impact on surrounding neighborhoods than the noise generated by the crushing plant, which is at a fixed location and can be effectively screened from the nearest residences. For these reasons, with application of Standard Conditions & Regulations and mitigation measures, temporary increases in ambient noise levels during project construction are considered mitigated to a level of less than significant. 11.e Noise Impacts from Public Use Airport NO IMPACT As noted in Topic 7e, the nearest public use airport is Palm Springs International, located approximately two and one half miles to the southeast. The project is not within an airport land use plan and is located more than two miles from the nearest public use airport. Therefore, the project will not be affected by significant noise from any public use airport and no mitigation is required. September 27,2004 Page 90 City of Palm Springs "Crescendo-(TTM 31766), Case No. 5-0996-PD-294 Initial Study -1 11.f Noise Impacts from private Use Airport NO IMPACT As noted in Topic 7f, no private use airports are within two miles of the project site nor is the project within an airport land use plan. Therefore, the project will not be affected by significant noise from any private use airport and no mitigation j is required. MITIGATION PROGRAM - NOISE IMPACTS Project Design Features There are no special project design features related to noise. Standard Conditions & Regulations SC 11-1 The project shall comply with the Construction Site Regulations (Municipal Code, Chapter 8.04.220) which restrict the operation for construction equipment between the hours of 5 p.m. and 8 a.m. if the noise produced is of such intensit y or quality that it disturbs the peace and quiet of any other person of normal sensitivity. These requirements shall be included on the contractor specifications and shall be verified by the Building Official for both on site and offsite construction. SC 11-2 Future on-site development shall comply with all relevant noise policies set forth in the Palm Springs Noise Ordinance (Municipal Code Chapter 11,74) to ensure that site operations do not create adverse noise impacts beyond the site boundaries. Mitigation Measures MM 11-1 All construction vehicles and equipment, fixed or mobile, operated within 1,000 feet of a dwelling shall be equipped with properly operating and maintained mufflers. This requirement shall be included on the contractor specifications and shall be verified by the Building Official. MM 11-2 Stockpiling and/or vehicle staging areas shall be located onsite and as far as practical from sensitive noise receptors (i.e. residential homes located south and east of the project). This requirement shall be included on the contractor specifications and shall be verified by the Building Official. MM 11-3 Rock crushing equipment shall be located at the extreme northwest corner of the property. MM 11-4 A berm of processed rock shall be constructed and maintained of sufficient height to screen the rock crushing operation and maintain off-site noise levels of 53 dB (Lso) or less at existing residences to the September 27, 2004 Page 91 City of Palm Springs -Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study i - east and south. If one crusher is used, the berm height shall be fifteen feet on the east and twelve feet on the south. If two crushers are used, the berm height shall be twenty feet on the east and seventeen feet on the south. MM 11-5 The developer shall contact the owner of Tram Way to obtain a temporary right-of-access for construction and delivery truck traffic to use Tram Way. If the owner of Tram Way is unwilling to grant such a truck access route, a construction access plan shall be developed and implemented if Racquet Club Drive is used by vehicles of three or more axles. The access plan would limit the number of vehicles per hour and the time of day that access is allowed. The construction access plan shall include the following measures: • Truck access shall not occur before 7:00 a.m. (8:00 a.m. on j Saturday). • No construction trucks shall operate on Racquet Club Drive after 3:00 p.m. when children may be playing, riding bikes, etc. • Truck traffic shall be limited to no more than three (3) trucks in j and three (3) trucks out each hour by vehicles with three or more axles. • Truckers shall be warned to not use engine decompression ('fake brakes") when traveling downhill for any access alternative. Violators will be banned from site access after failing to heed a first warning. MM 11-6 Surficial material and boulders shall be stockpiled to create a temporary noise berm prior to crusher operation. The crusher shall operate behind this temporary berm until such time as the permanent berm described in MM 11-4 has been created. After application of Project Design Features, Standard Conditions 8 Regulations, and Mitigation Measures outlined above, noise impacts were determined to be mitigated to a level of less than significant.

POPULATION AND HOUSING Would the proposal: a) Induce substantial population growth in an ❑ ❑ ❑ ■ area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other September 27, 2004 Page 92 City of Palm Springs 'Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study infrastructure)? b) Displace substantial numbers of existing ❑ ❑ ❑ ■ housing, necessitating the construction of replacement housing elsewhere? c) Displace substantial numbers of people, ❑ ❑ ❑ ■ necessitating the construction of replacement housing elsewhere? IMPACT ANALYSIS -i 12.a Induce Substantial Population Growth NO IMPACT. I The proposed project is located at the fringe of urban development. All major utilities needed to serve the site are readily available and no major utility or road extensions are necessary. Although new housing is proposed, site development at residential densities of two units per acre and resident population of 213 persons (based on 2.52 persons per household for L2 designation per General Plan Land Use Density/Intensity Table, GP page 1-26) was anticipated by the City's General Plan and does not constitute population growth beyond what has been planned. For the reasons stated above, the project does not serve to induce either direct or indirect population growth and no mitigation is required. 12.b Substantial Displacement of Housing NO IMPACT. The project site is currently vacant, containing no existing housing population. Consequently, displacement of housing would not occur as a result of the project and no mitigation is required. For these reasons, the project does not serve to displace existing housing and no mitigation is required. 12.c Substantial Displacement of People NO IMPACT, The project site is currently vacant, containing no existing resident population. Consequently, displacement of people would not occur as a result of the project and no mitigation is required. For these reasons, the project does not serve to j displace people and no mitigation is required.

(Source 12) ❑ ❑ 0 ❑ e) Other public facilities? ❑ ❑ ❑ IMPACT ANALYSIS The proposed project will not increase demand for public services beyond those anticipated by the City's General Plan, which currently designates the site for residential development at a density of 2 units per acre. Development of the site is an incremental and logical extension of public services to an infill area on the fringe of existing urban development. 13.a Adverse Effects on Fire Protection Facilities or Services POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED The project proposes to construct new residential structures, which would increase the demand for fire protection services in the area. Fire protection would be provided by the Palm Springs Fire Department (PSFD) from station #443 (one September 27, 2004 Page 94 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study Of five City fire stations) located at 590 West Racquet Club Road, a Pproximately one mile east of the project site. The PSFD has set a maximum acceptable fire response time of five minutes and all structures beyond this primary response area are required by City ordinance to install automatic fire sprinklers and other built-in fire protection equipment, as deemed appropriate by the Fire Department. As discussed in Section 7.h and shown in Exhibit 17, the five-minute response boundary for station #443 falls within the project site and any dwellings which are constructed outside this response area are required to comply with City Municipal Code Section 11.02.020. Also discussed in Section 7.h is the project location at an urban/wildland fire interface, as are other neighborhoods in the Little Tuscany area. This, along with other projects presently being built in Palm Springs, will bring added residents to the community resulting in an increased demand for fire protection services. In order to address this increased demand, the City intends to form an Assessment District to provide additional funding to the fire department. The project will be required to support the formation of such a district to mitigate impacts on fire protection services. Since the project will participate in the assessment district, impacts of the project on fire protection services are considered mitigated to a level of less than significant. Prior to ap proval of tentative tract map entitlements, the project will be reviewed by the PSFD and conditioned for necessary fire protection requirements (hydrant locations, fire flow volume, fire resistant construction, primary and secondary access, fire sprinklers, vegetation management, etc.) Therefore, standard City protocols for tentative map review and the imposition of reasonable conditions of approval would ensure that project implementation would result in a less than significant impact on fire protection services. 13.b Adverse Effects on Po/ice Protection Facilities or Services POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED The project proposes to construct new residential structures, which would increase the demand for law enforcement services in the area. Law enforcement services would be provided by the Palm Springs Police Department (PSPD). The PSPD is headquartered at 200 South Civic Drive, approximately 3 miles southeast of the subject property. According to the Police Department's web site, current police staffing consists of 92 sworn personnel and 56 classified personnel. This results in a staffing/population ratio of 1:500. According the General Plan EIR, 1.5 officers per 1000 population (1.5:1000) is a sufficient ratio. The Palm Springs Police Department also has a mutual aid agreement with the Riverside County Sheriff's Department. Funding for the Police Department comes from the City s General Fund. This, along with other projects presently being built in Palm Springs, will bring added residents to the community resulting in an increased demand for police protection. In order to address this increased demand, the City intends to form an Assessment District to provide additional funding to the police department. The project will be required to support the formation of such a district to mitigate impacts on law enforcement services. Since the project will participate in the assessment district, impacts of the project on police protection services are considered mitigated to a level of less than significant. The project would be developed in accordance with Section II (Building Security Regulations) of Chapter 8.04 of the Palm Springs Municipal Code. Prior to approval of tentative tract map entitlements, the project will be reviewed by the September27, 2004 Page 95 City of Palm Springs "Crescendo"(TTM 31766), Case No. 5-0996-PD-294 Initial Study PSPD and conditioned for necessary law enforcement requirements. Therefore, standard City protocols for tentative map review and the imposition of reasonable conditions of approval would ensure that project implementation would result in no significant impact on law enforcement services. i . 13.c Adverse Effects on School Facilities or Services POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED The project proposes to construct new residential structures, which would increase the demand for educational services in the area. The project is within the Palm Springs Unified School District (PSUSD) attendance area. Based on generation factors provided by the PSUSD', the proposed project would generate approximately thirty six students (eighteen in kindergarten through 5'grade, nine in 6"' through 8" grade, and nine in 9`^ through 1211' grade). Students generated by the proposed project would attend Katherine Finchy Elementary, Raymond Cree Middle School, and Palm Springs High School. Raymond Cree Middle School -;� and Palm Springs High School are below capacity and would be able to accommodate students generated by the project. Attendance at Katherine Finchy Elementary is below, but approaching capacity. School boundaries are adjusted periodically to redistribute student attendance more equitably throughout the district. Under state law, the proposed project will be required to pay the required school impact fee (currently $2.14 per square foot) to reduce the potential impact of additional students. 13.d Adverse Effects on Park Facilities or Services LESS THAN SIGNIFICANT IMPACT Development of the project would result in an increased demand for park and recreation facilities. The City of Palm Springs Parks and Recreation Department is responsible for park facilities within the City and indicates that the City maintains a 5:1 standard ratio of park area acreage to one thousand population. The project will be required to dedicate land or contribute in-lieu fees for the provision of park facilities at the required ratio. For these reasons, project implementation will result in no significant impacts to park facilities and no additional mitigation is required. 13.e Adverse Effects on Other Public Facilities or Services LESS THAN SIGNIFICANT Development of the project will result in an increased use of public facilities including roads, utilities, schools, parks, libraries, police and fire protection services. However, the ongoing maintenance of these facilities is funded through �I the collection of taxes and other funding sources to maintain City facilities in acceptable condition. The project applicant shall be required to pay for the construction of internal roadways proposed at the site. The maintenance of these roadways will be the responsibility of the project Homeowners Association once the build out is completed. Therefore, the project will not result in an unusually heavy burden on the maintenance of public facilities. For the reasons stated 1 Student Generation Factors(Students per household) =0.2125 for elementary,0.1084 for middle school,0.1091 for I high school September 27, 2004 Page 96 City of Palm Springs "Crescendo"(T7-M 31766), Case No. 5-0996-PD-294 Initial Study i above, project implementation would result in no significant impacts to public services and no additional mitigation is required.

Mitigation Measures MM 13-1 The project will bring a significant number of additional residents to the community. The City's existing public safety and recreation services, including police protection, criminal justice, fire protection and suppression, ambulance, paramedic and other safety services. Accordingly, the City may determine to form a Community Services District under authority of Ordinance C.

(Source 1, 12) IMPACT ANALYSIS 14.a Cause Substantial Deterioration of Existing Parks through Increased Use LESS THAN SIGNIFICANT IMPACT. I The construction of this project would increase the potential demand for park and recreational facilities. As a standard condition of approval, the project would be required to dedicate land or pay in-lieu fees at the City's standard ratio of 5 acres of park land to 1,000 population as required by the City Ordinance 1632, establishing park fees. Therefore, new parks or park improvements would be funded by the project and project implementation would result in less than significant impacts to recreational facilities. ci 14.b Cause Adverse Effects by Constructing New or Expanded Recreational Facilities NO IMPACT. The project proposes to construct pedestrian walkways and passive recreational features as amenities to serve the project and immediate neighborhood. However these are small and serve to augment the g project and enhance public pedestrian connectivity and passive recreation opportunities rather than acting as a discrete September 27, 2004 Page 98 City of Palm Springs 'Crescendo"(TTM 31766), Case No. 5-o996-PD-294 Initial Study land use that would generate any significant environmental impacts.

IMPACT ANALYSIS 15.a Traffic volume and Street Capacity Impacts LESS THAN SIGNIFICANT. This discussion is based on a Traffic Study prepared for the project by George Dunn Engineering dated January 12, 2004. i Existing roadway and intersection conditions in the immediate vicinity of the project include the following: North Palm Canyon Drive (Highway 111)- North Palm Canyon Drive is a four lane paved public roadway oriented general) north-south ap proximately one-quarter mile east of the project. Tram Way-Tram Way is an east-west oriented two lane paved private roadway that borders the southern project boundary. Tram Way intersects North Palm Canyon Drive approximately one quarter mile east of the project. This intersection is presently signalized with north-south protected left turn phasing. West Racquet Club Drive - West Racquet Club Drive is an east-west oriented public roadway that borders the southern project boundary. West Racquet Club Drive intersects North Palm Canyon Drive approximately one quarter mile east of the project. This intersection is presently signalized with a two-phase traffic signal. In order to evaluate the project traffic impacts, background traffic information was obtained for relevant intersections. The intersection of West Racquet Club Drive and North Palm Canyon Drive was determined by the City to be the one key intersection requiring analysis. AM (7:00-9:00 AM) and PM (4:00-6:00 PM) peak Septernber27, 2004 Page 100 City of Palm Springs "Crescendo-(T7-M 31766), Case No. 5-0996-PD-294 Initial Study turning movement traffic counts were collected at the Palm Canyon Drive intersection with Racquet Club Drive in January 2002. These counts represent a worst case analysis since they reflect traffic generated during the peak tourist season when traffic counts are highest. Since the project proposes no access onto Tram Way and no project traffic would be generated at the intersection of Tram Way and Palm Canyon Drive, this intersection was not analyzed and no traffic counts were collected. The report also obtained existing Year 2000 average annual traffic counts from the California Department of Transportation (CALTRANS) and forecast year 2020 Average Daily Traffic (ADT) volumes from the Coachella Valley Association of Governments (CVAG) for use in the analysis. A twenty-year average annual growth rate of 4.0% was assumed to incorporate forecast growth due to background traffic. I The analysis of peak hour intersection Level of Service (LOS) is the primary 1 indicator of circulation system performance. The project traffic study used the 2000 Highway Capacity Manual Operations methodology to conduct the LOS analysis. Levels of Service for peak hour intersection analysis are summarized below: LOS A- Optimal conditions, insignificant delays (< 10 seconds) LOS B - Stable operation, minimal delays (10.1 - 20 seconds) LOS C-Stable operation, acceptable delays (20.1-35 seconds) LOS D -Approaching Unstable, tolerable delays (35.1-55 seconds) LOS E- Unstable operation, significant delays (56.1-80 seconds) LOS F-Forced Flow, excessive delays (> 80 seconds) The project trip generation as determined by the traffic study is summarized in Table 8 below.

The effect of September 27, 2004 Page 101 City of Palm Springs "Crescendo"(7TM 31766), Case No. 5-0996-PD-294 Initial Study t this additional traffic on key intersections was analyzed to compare the existing and future traffic conditions without the project to the future traffic conditions with the project. The intersection of West Racquet Club Drive and North Palm Canyon Drive was determined to be the one key intersection requiring analysis. This intersection currently operates at a Level of Service (LOS) B in both the a.m. and p.m. peak hours. According to the traffic analysis, the addition of future traffic from the proposed project will not change the LOS for this intersection and it will continue operating at LOS B. Levels of service categories are similar to report card ratings for traffic performance. LOS B reflects an average delay of 10- 15 seconds per vehicle and is considered a very good functional level with only short delays during the periods of peak travel demand. Level of Service D is considered the minimum LOS acceptable to the City(General Plan policy 7.1.7). i J For these reasons, project implementation will not result in increased traffic volumes that cause congestion on existing adjacent streets or at key intersections and no mitigation is required. 15.b Exceed Level of Service Standard on a Designated Road or Highway NO IMPACT The design of the surrounding street system reflects the Circulation Element of the City's General Plan and is based upon the estimated vehicular trips generated by the designated land uses and densities contained in the Land Use Element of the General Plan. Since the project maintains the overall General Plan density, project related traffic impacts are consistent with those that have already been considered in the General Plan EIR. The only General Plan streets adjacent to the project are Tram Way (designated as a Major Thoroughfare) and West Racquet Club Drive (designated as a Secondary Thoroughfare). Tram Way is a semi-gated private roadway with controlled public access to the Palm Springs Aerial Tramway. West Racquet Club Road acts as a local collector for the project site and surrounding neighborhoods, conducting traffic to and from North Palm Canyon Drive (Highway 111). To maintain level of service standards, the project will be required to pay the Transportation Uniform Mitigation Fee (TUMF), a fee designed to off-set the traffic impacts of new construction on the regional roadway network. In addition, new rom development projects are P P 1 typically required to improve adjacent streets to their full half width improvement standard in order to construct the City's General Plan circulation system. West Racquet Club Drive would fall within this category and would be constructed by the project in accordance with City requirements. As noted in the discussion under Item 15a above, the project traffic report determined that the intersection of West Racquet Club Drive and North Palm Canyon Drive will operate at LOS B in 2005 with and without the project and in 2020 with the project. It concludes that,"The area roadways will continue to operate at acceptable levels of service in the Year 2005, the project opening year date, and the Year 2020." Level of Service D is considered the minimum LOS acceptable to the City (General Plan policy 7.1.7). For these reasons, the level of vehicle trips will not exceed a level of service standard for a local or regional roadway and no mitigation is required. 1 ' September 27, 2004 Page 102 City of Palm Springs "Crescendo-(7TM 31766), Case No. 5-0996-PD-294 Initial Study 1 15.c Adverse Impacts on Air Traffic Patterns NO IMPACT As noted in Section 7, the project is more than two miles from the Palm Springs International Airport. It is located near the San Jacinto Mountains and is not in i the path of direct over-flights. The 79 proposed residential units would not cause a substantial increase in air passengers or flight volume. For these reasons, the project will have no impact on air traffic patterns, levels or safety risks and no mitigation is required. 15.d Adverse Impacts on Traffic Safety due to Dangerous Design or Incompatible Use NO IMPACT The project is located at the upper end of West Racquet Club Drive, where existing traffic volumes are low. All streets proposed by the project are linear and there are no curves to cause sight distance or other safety concerns. Project entries intersect at 90 degrees with existing roads. In addition, standard City protocol requires all engineered street plans to be reviewed and approved by the City's Public Works Department before any construction can occur. Project land uses are compatible with those around it so no vehicular incompatibilities are evident. For these reasons, project implementation would not create unsafe design features or incompatible uses that would substantially increase traffic safety hazards and no mitigation is required. 15.e Inadequate Emergency Access NO IMPACT Standard City protocol requires all projects to undergo review by the Palm Springs Fire Department (PSFD). The project provides two points of vehicular access to each lot consistent with PSFD guidelines. For these reasons, project implementation would not result in inadequate emergency access and no mitigation is required. 15.f Inadequate Parking Capacity NO IMPACT The project would be required to comply with the City of Palm Springs Municipal Code parking requirements for single family residences within a Planned Development District. The parking requirements are based on the number of single family residential units along with a factor for guest parking and will be evaluated by the City during its development review process. A typical single family residence with a two-car garage will accommodate four on-site spaces (two inside the garage and two on the driveway apron), which satisfies the parking needs of a typical single family residence. 28' wide streets will alsso provide on-street parking on one side. Additional garage space or a wider driveway apron could be provided to provide additional parking if required. For these reasons, project implementation would not exceed parking capacity requirements and no mitigation is required.

Transit service is available at North Palm Canyon Drive. For these reasons, project implementation would not conflict with adopted alternative transportation policies, plans or programs and no mitigation is required.

The City of Palm Springs operates the Wastewater Treatment Plant serving this project. Project wastewater entering the City sewer system would be generated by single family residences that would cause concern upon their discharge from the treatment plant. In addition, operation of the wastewater treatment plant is regulated by the Regional Water Quality Control Board and standard permitting and monitoring protocols ensure that treatment requirements for waste discharges are not exceeded. For these reasons, project implementation would not exceed RWQCB wastewater treatment requirements and no mitigation is required. _ 16.b Adverse Effects from Construction of Water or Wastewater Treatment Facilities NO IMPACT. Wastewater collection service to the project would be provided by the City of Palm Springs. The project would be designed to gravity flow to an existing sewer main in Racquet Club Drive at Girasol Avenue, requiring installation of about 300 feet of offsite sewer line to reach the project site. The project is consistent with the density provisions of the City's Wastewater Master Plan, which is designed to a accommodate General Plan build out projections. The General Plan EIR states that implementation of the General Plan, including land uses proposed on this September 27, 2004 Page 105 i I City of Palm Springs -Crescendo'(TTM 37766), Case No. 5-0996-PD-294/nitia/Study site, will not have a significant effect upon the City's sewer system. For these reasons, project implementation would not require the expansion or new construction of wastewater treatment facilities nor would it result in a determination of inadequate capacity to serve the project or the community and no mitigation beyond Standard Conditions Er Regulations is required. Domestic water service to the project would be provided by the Desert Water Agency (DWA). The project is served by DWA Reservoir No. 20 (3.5 million ;•� gallons), which has adequate water storage capacity to meet present and future domestic and fire flow requirements for the area, including the project. From the reservoir, water would be pumped to the upper portion of the project to achieve fire flow volumes, while water to the lower portion of the project would operate under a gravity pressure system. DWA indicates that the lower area (the Palm Springs North Base System) currently has no system deficiencies while the upper area (the Chino West Zone) has deficient pumping capacity and provides only marginal fire flow to existing residences. The minimum required fire flow without automatic sprinklers is 1,500 gallons per minute for a two hour duration while the fire flow with automatic sprinklers is 1,000 gallons per minute foe a two hour duration. Pumping equipment serving the upper zone currently achieves between 750 and 1.000 gallons per minute flow and would require upgrade of the pumping facilities and installation of approximately 1,200 linear feet of new pressure line in Milo Drive to adequately serve the upper portion of the project. The requirement for upgrade of pumping facilities and extension of offsite water pressure lines would be included as part of the City Standard Conditions & C Regulations for the project. For these reasons, although project implementation would require the expansion and upgrade of water delivery infrastructure, no new or expanded water treatment facilities would be needed that would result in a determination of inadequate capacity to serve the project or the community and no mitigation beyond Standard Conditions & Regulations is required. 16.c Adverse Effects from Construction of Storm Water Drainage Facilities i NO IMPACT. The City of Palm Springs has responsibility for storm drain lines that would serve the project, however, none exist in the site vicinity. As discussed in Section 8, the project will provide on-site detention facilities and storm drain lines to address the drainage collection and discharge requirements of the project and, although not required to serve this project, will construct the segment of Master Storm Drain Line 2 that crosses the project site. These facilities are contained within the development footprint and their environmental impacts are evaluated herein. For these reasons, project implementation will have no impact on new or expanded offsite drainage facilities and no mitigation is required. 16.d Availability of Sufficient Water Supply POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED Desert Water .(DW) has responsibility for water service to the project site. DW water supply is obtained from groundwater wells, with supplemental water from the Metropolitan Water District's Colorado River Aqueduct. The proposed project would generate a demand of approximately 7.6 million gallons of water annually September27 2004 Page 106 I City of Palm Springs "Crescendo-(7TM 31766). Case No. 5-0996-PD-294 lnitia/Study I (assuming 260 gallons/unit/day). The DW has indicated that it has sufficient water supply to serve the project, therefore, the project would not significantly affect the provision of water service by DW within its jurisdiction. DW has noted that the Whitewater River groundwater sub-basin is currently in an overdraft condition. By supplying water to the proposed project, DW would be contributing cumulatively to this overdraft. Due to its large size, basin management is possible with replenishment using surplus water during wet years and draw down during dry ones. Long-term ground water levels are being stabilized by actions including the practice of artificial recharge of State Water Project supplies and other surplus water, orderly expansion of the recycled water system and aggressive investment in and promotion of conservation programs. Based on its on-going management plans, the DW has determined that there is sufficient water supply for the project. To minimize water consumption, the project will follow water conservation guidelines included within the Palm Springs General Plan Update EIR (Page 5- 100), the Palm Springs General Plan (Pages II-63 and II-64). and the City's Water Efficient Landscape Ordinance to mitigate the impacts to public water supplies. These would include the use of drought tolerant plants in landscaping. j For these reasons, the project has sufficient water supply from existing entitlements and resources Procured by the DW such that impacts to water supply would be less than significant and no additional mitigation is required. 16.e Sufficiency of Wastewater Treatment Capacity NO IMPACT. Wastewater treatment service to the project would be provided by the City of Palm Springs. The project is consistent with the density provisions of the City's Wastewater Master Plan, which is designed to a accommodate General Plan build out projections. The General Plan EIR states that implementation of the General Plan, including land uses and density proposed on this site, will not have a significant effect upon the City's sewer system. For these reasons, wastewater treatment capacity is adequate to serve the project and the existing community and no mitigation is required. 16.f Sufficiency of Lancifiii Capacity NO IMPACT. Solid Waste collection services would be provided to the project by the Palm Springs Disposal Service (PSDS). Solid waste generated by the project would be sent to the Edom Hill transfer station located in the City of Cathedral City. The Edom Hill transfer station is an 8-acre facility operated by Waste Management Inc. with a permitted throughput of 2,600 tons per day. The transfer station is operating on the premises of the Edom Hill Landfill, which is scheduled to close in the Fall of 2004. Solid waste sent to the transfer station will be transported to various landfills, all of which have capacity to accommodate waste from the project. September 27, 2004 Page 107 i City of Palm Springs 9 "Crescendo"(17-M 31766), Case No. 5-0996-PD 294 Initial Study The Lamb Canyon Landfill is located at 16411 State Highway 79 in Beaumont. The landfill is sited on 353 acres, of which 145 acres_ are currently being used for disposal. The landfill was permitted for expansion on December 16, 2003 and currently has a remaining capacity of 25,967,000 cubic yards, which is projected to accommodate solid waste demand until the projected closure date of January 1, 2023 based on a permitted throughput of 3,000 tons per day. The Badlands Landfill is located at 31125 Ironwood Avenue in Moreno Valley. The landfill is sited on 1,093 acres, of which 150 acres are currently being used 1 for disposal. The landfill was permitted for expansion on July 30, 2001 and currently has a remaining capacity of 15,036,809 cubic yards, which is projected to accommodate solid waste demand until the projected closure date of January 1, 2018 based on'a permitted throughput of 4,000 tons per day. f The El Sobrante Landfill is located at 10910 Dawson Canyon Road in Corona. { The landfill is sited on 1,322 acres, of which 495 acres are currently being used ;± for disposal. The landfill was permitted for expansion on June 6, 2001 and currently has a remaining capacity of 184,930,000 cubic yards, which is projected to accommodate solid waste demand until the projected closure date of January 1, 2020 based on a permitted throughput of 10.000 tons per day. The project would generate approximately 360 pounds per day of solid waste (assumes ten pounds/unit/day), which is negligible compared to the combined capacity of the various landfills serving the site via the Edom Hill Transfer Station. For these reasons, the project will be served by landfills with sufficient permitted capacity to accommodate the project's solid waste disposal needs and no additional mitigation is required. 16.g Compliance with Solid Waste Regulations I NO IMPACT. Solid waste from the project would be generated by single family residences for curbside pickup and be subject to the collection requirements of the solid waste provider, that precludes the disposal of hazardous substances to the landfill. For these reasons, project implementation will comply with federal, state and local solid waste regulations and no additional mitigation is required. MITIGATION PROGRAM - UTILITIES Project Design Features There are no special project design features related to utilities. Standard Conditions & Regulations SC 16-1 The developer shall be responsible for system improvements to pumping facilities and pressure lines as required by the Desert Water Agency to achieve a minimum of 1,000 gallons per minute fire flow to all buildings provided with sprinklers and a minimum 1,500 gallons per minute fire flow to all buildings without sprinklers.

MANDATORY FINDINGS OF SIGNIFICANCE a) Does the project have the potential to degrade ❑ ❑ ❑ 0 the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of California history or prehistory? b) Does the project have impacts that are individ- ❑ 0 ❑ ❑ ually limited, but cumulatively considerable? ("Cumulatively considerable' means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? c) Does the project have environmental effects ❑ ❑ ❑ which will cause substantial adverse effects on human beings, either directly or indirectly? The information provided in this section summarizes the results of analyses contained in the preceding Sections 1 through 16 of this document. September 27, 2004 Page 109 j ! City of Palm Springs "Crescendo" (TTM 37766), Case No. 5-0996-PD-294 Initia/Study 17.a Does the Project have Potential impacts that will Degrade the Environment NO IMPACT. As discussed in preceding sections, the proposed project will not cause impacts to the environment that cannot be mitigated to less than significant levels. In Particular, the discussion of biological and cultural resources in Sections 4 and 5 identified no impacts to these resources and no mitigation was required. °j 17.b Does the Project have Impacts that are Cumulatively Considerable POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. As discussed in preceding sections, the development of single family housing will contribute an incremental increase in the cumulative demand for City services, use of public roads, demand for additional supplies of domestic water, and `i generation of additional wastewater and solid waste. However, the proposed Project is consistent with the City's General Plan density and was accounted for in local and regional infrastructure planning efforts and growth projections. The level of increase caused by the proposed project is minimal due principally to the small size Of the Project (79 units) and its location as an infill site adjacent to existing residential development. Cumulative impacts to City services were iidentified and will be mitigated through participation in an Assessment District to provide adequate funding levels. Cumulative impacts to water supply are being addressed through the ongoing basin management efforts of Desert Water, who has indicated that they have adequate water supply to serve this project. 17.c Does the Project have Impacts with Adverse Effects on Human Beings POTENTIALLY SIGNIFICANT UNLESS MITIGATION INCORPORATED. As discussed in preceding sections, the proposed project is not anticipated to result in any environmental effects upon human beings either directly or indirectly that cannot be mitigated to less than significant levels. From the environmental analysis contained in this Initial Study, the following issues were determined to have no potential for significant environmental impact if the project is implemented as proposed: agricultural resources; biological resources, cultural resources; geology Et soils; hazards Er hazardous materials; mineral resources; noise (long term operational impacts); hydrology/water quality; population/housing; public services; recreation; and transportation/traffic. The proposed project has the potential to have significant impacts related to aesthetics; air quality; land use/planning; noise (short-term construction-related impacts) and utility/service systems unless the recommended mitigation measures are incorporated into the project. Based on the overall findings in this Initial Study, the City will prepare a Negative Declaration for Change of Zone No. 5.0996, Tentative Tract Map No. 31766, and Preliminary Planned Development District No. 294 and vacation of the westerly 25 feet of right-of-way for Vista Grande Avenue.
