II. CONFIRMATION OF THE AGENDA - Confirmed III. PUBLIC COMMENT: None IV. CONSENT CALENDAR A. Chairman Abels asked if there were any changes to the Minutes of January 14, 1997. Commissioner Tyler asked that the minutes be amended on Page 4, Item 9 to state "...asked why there wasn't a warrant number that....."; Item 10 add the word "...not conditioning..."; Page 5, Item 15 be changed to state that Lot 105 was an example; Page 13, Item 18 was to be reworded. There being no further changes to the minutes, it was moved and seconded by Commissioners Gardner/Tyler to approve the minutes as amended. B. Department Report: None V. PUBLIC HEARINGS A. California Environmental Quality Act Guidelines; a request of the City for consideration of an Amendment to the CEQA Guidelines for the City of La Quinta in compliance with State requirements concerning environmental procedures. PC 1-28-97 Planning Commission Meeting January 28, 1997 1. Chairman Abels stated that a request had been received by staff to table this issue until further notice. The item was tabled until further notice and would be re -advertised for a new hearing date. B. Zoning Ordinance Amendment 96-054; a request of the City for consideration of Amendments to the La Quinta Municipal Code, by revising Title 9 (Zoning, Regulations) relating to various chapters dealing with such items as height limitations, setbacks, Hillside Conservation, Bed and Breakfast regulations, and Cove Residential Development Standards. 1. Chairman Abels opened the public hearing and asked for the staff report. Community Development Director Jerry Herman presented the information contained within the staff report, a copy of which is on file in the Community Development Department. 2. Mr. Chris Canaday, stated he was an architect who was developing homes for property owners within the Lake La Quinta project. They were looking to develop the remaining 150 lots and he was anticipating submitting plans for plan check for the waterfront homes. Their concern was with the proposed rearyard setbacks. There were certain lots that had disadvantages and he was working on a courtyard design to minimize those disadvantages. Based on the Compatibility Standards, the footprints for the remaining lots on the southeasterly corner of the property along the easterly boundary, would not work and allow room for pools. Along the easterly boundary there are high tension power lines along the property line and the property owners are wanting pools and spas. With the power lines in the rear, 20-foot setbacks, and the constraints of the minimum house size, it is difficult to make the footprint work and have room for a pool. In addition, there are lots that have upsloping rear yards (Lots 103-110) with five foot rear fences making a total height of ten feet from the street elevation. This would block the homeowners' view. They are proposing to design a courtyard with front yard pools and requesting a ten foot setback instead. 2. Commissioner Woodard asked where the view was for Lots 103-111 as it appears the houses across the street would block their view. Mr. Canaday stated the problem with Lots 103-113 was not the front view, but rather the rear yard with the 5-foot upslope and additional 5-feet of fence, there was no view. They are trying to design a courtyard home that has a frontyard orientation. PC 1-28-97 2 Planning Commission Meeting January 28, 1997 3. Mr. Billy Watson, Watson Company, stated he was designing and hoping to build a home in Lake La Quinta for one of his clients. He had received approval from the Design Review Board of the Homeowners' Association. He submitted the plans to staff and was informed that the ordinance had changed. Even though this plan conforms to the style and colors of the existing homes, it would have to be submitted to the Planning Commission for compatibility review during a public hearing. The proposed home is to be constructed on Lot 273 and will be approximately 3,200-3,300 square feet. His client has sold his home in anticipation of being able to move into this one by the end of June. If he has to go through the public hearing process, he will not be able to meet their deadline. Community Development Director Jerry Herman stated this house is caught in the regulations of the revised Zoning Ordinance- compatibility review. As the old ordinance allowed for staff approval, the revised Ordinance requires a public hearing before the Planning Commission. In this case, Mr. Watson owns a lot that is part of an existing development and the only way to obtain the approval he needs to construct the house is with a public hearing before the Planning Commission. Staff went on to explain how the Ordinance had changed. 4. There being no further public comment, Chairman Abels closed the Public Hearing and opened the item for discussion. 5. Commissioner Gardner asked what kind of advance notice is given to builders when staff is proposing changes to the Zoning Code. Could this contractor have submitted his application before the change occurred. Community Development Director Jerry Herman stated staff has no way of knowing when a contractor is going to submit their plans for plan check. Therefore, staff has no way of informing them. When changes are proposed to the Planning Commission and City Council, there is no way of knowing what changes will be approved by the Commission and Council until they are approved. However, we do advise people who come to the counter about potential changes. 6. Commissioner Gardner asked if in Mr. Watson's case, the Planning Commission could grant a deviation. Community Development Director Jerry Herman stated they could do so through a public hearing. However, Mr. Watson does not need a deviation, his project is caught in the changes that were made to the compatibility review process. If Mr. Watson were to submit his plans for Commission review, staff would have to advertise and this would require 20-25 days prior to the date of the hearing. If the Commission determines to change the ordinance to alleviate this problem, the change in the ordinance would not take affect until approximately April. PC 1-28-97 3 Planning Commission Meeting January 28, 1997 7. Commissioner Woodard stated that it should be the responsibility of the architects to monitor the cities they do business with for any proposed changes to their zoning ordinances. This would enable them to be prepared. Commissioners discussed alternatives to the processing procedures. 8. Following the discussion, staff went on to review all the proposed changes to the Zoning Code that were being submitted to the Commission for their review. 9. Page 30-3. Commissioner Butler stated his concern about lot coverage and rear yard setbacks. Staff explained that due to the problems they were experiencing, staff was requesting to make the rear yard setback 10-feet. Staff went on to cite examples of how the 20-foot setback was causing problems. Commissioner Butler stated he did not want this to change the lot coverage; he did not want large houses on small lots. The 40% lot coverage could be retained to address this. 10. Commissioner Tyler suggested that instead of making it a blanket 10-foot setback for all lots, that the 10-foot setback be retained for existing recorded lots and 20-feet for those recorded after the effective date of the Ordinance. Staff stated that the 10-foot rear yard for existing recorded lots at the time of the effective date of the Ordinance and all new lots created after the effective date would be required to have the 20-foot setback with a 40% lot coverage. 11. Page 30-4 - Commissioner Tyler questioned the wording in Section F.2. Staff would reword the section to clarify the minimum bathroom requirements. 12. Page 30-8 - Commissioner Tyler asked why staff was deleting D.2. Staff explained that it was changed due to the General Plan Amendment to eliminate the RL District as the City does not have a Rural Residential Overlay District in the RL District. 13. Page 60-41.1 - Commissioner Woodard asked if you have a meandering sidewalk, how would you determine the dimension, from the sidewalk or back of curb. Staff agreed that the dimension could not be determined when a meandering sidewalk was used, therefore sidewalk would be eliminated and the applicant would be responsible for the dimension at.the back of the curb only. 14. Page 60-3 - Commissioner Tyler questioned why staff changed the sideyard setback from 12 to 8-feet for Section D.2. Staff stated this change will need to be determined after the RV issue is resolved and will be kept as it is for now. PC I -28-97 4 Planning Commission Meeting January 28, 1997 15. Page 60-5.13.3 - Commissioner Tyler asked that the words "or flag lot" be added to the end of the sentence. 16. Page 60-8.4 - Commissioner Tyler asked how staff determined that 24-feet was an appropriate size for a satellite dish. Staff stated it was determined by the size of the antennas that are currently in existence. 17. Page 60-9.D.4. - Commissioner Woodard asked why staff determined to draw the line at 10 acres. Staff stated that it was an arbitrary number determined by staff. Commissioner Woodard stated that ten acres could hurt the development of a compound and five acres would be better. It was determined to change the acreage to five. 18. Page 60-11.B.3. - Commissioner Tyler asked that the last sentence be deleted as this was a matter of law, and how would staff police this. Isn't this governed by Section 7. Staff agreed and the last sentence would be deleted. 19. Page 60-15.13.5 - Commissioner Woodard asked for clarification as to why this was subject to the Community Development Director instead of the Commission. Staff stated it was for minor changes only. 20. Page 60-35 - Community Development Director Jerry Herman stated this was the section that was brought up at the beginning of the meeting regarding compatibility review. He then read the current code requirements and explained that Lake La Quinta is not a custom lot subdivision but a tract subdivision with different phases. He cited examples of custom lot subdivisions. Staff distributed copies of the original Ordinance and the revised Ordinance. What staff was proposing was to add to Section F, "A public hearing shall be noticed and held for Section 9.200.110 prior to Planning Commission approval or denial of any Site Development Permit consisting of four units or less under the Compatibility Review provision of this section. Therefore.... four units or less would be reviewed by the Planning Commission as a Business Item." He went on to explain that under the original Ordinance, staff was allowed to make a decision on any minor design deviation that was under 5% change in square footage and staff felt the construction of the product was similar to the original design. If staff did not want to make the determination, it was referred to the Planning Commission. With the revisions to the Zoning Ordinance, staff is no longer able to make these determinations. Commissioner Gardner asked if this authority was given back to staff how many lots are involved. Mr. Watson stated approximately 25 lots could be custom homes. Staff stated this change will not affect Mr. Watson as his house is more than a 5% change. The intent of the ordinance is not to go around the public hearing process for four units or less. Commissioner Gardner asked if there are 25 lots that could be approved PC I -28-97 5 Planning Commission Meeting January 28, 1997 as custom lots and a total of 300 lots that were previously approved, how could the 25 homes be separated out as custom homes. At PGA West there are a number of lots on the Stadium Course that were designated as custom home lots by the Specific Plan. A developer does a tract development or he does a lot for sale development and creates custom lots. City Attorney Dawn Honeywell stated the purpose of the Compatibility Ordinance was to keep consistency throughout the entire development of the tract. Discussion followed regarding how the Compatibility Ordinance was created and how Mr. Watson's problem could be resolved. It was determined that Mr. Watson's project would be scheduled for review before the Planning Commission at their meeting of February 25th. This would solve his immediate problem and staff was to revise the Zoning Ordinance to add the minor deviation approval by the Community Development Director for four units or less. Over four units would require a public hearing before the Planning Commission. 21. Page 60.37. Section 9.60.300 - Commissioner Tyler explained that the Starlight Dunes project wanted to build along the northern boundary of the project which also was a City boundary, but on the other side of the boundary there were single residential lots that back up to it but the houses were 300- feet away. This was not a privacy invasion, but as the Ordinance was written, the Starlight Dunes project would not be able to build any two story units along these lots. This was a way to allow relief to the developer. 22. Page 60-29-29.C.2 - Commissioner Seaton questioned 8 guests in four rooms plus the owner, it appeared to be a lot of guests and parking concerns. Commissioner Woodard stated this would be at least a five bedroom home and probably a newly constructed facility. Staff explained that anything up to four -five bedrooms could be converted provided the residents lived there. It is a conditional use permit process that would be brought to the Planning Commission for a public hearing. At that time the Commission could review the site plan and if they cannot meet the parking requirements, or if it does not meet the character of the existing neighborhood, it can be denied. Anything above four rooms is a motel and has to be included in a Commercial Zone. Commissioner Tyler asked that E.1 also be changed to read, "A minimum of 100 square feet is required for each of the sleeping rooms and not more than 25% of the structure can be used for rentals." 23. Page 100-9 - Commissioner Tyler asked how staff would enforce this. Staff stated it was an attempt to control the selling of outside produce. PC I -28-97 6 Planning Commission Meeting January 28, 1997 24. Page 140-4 - Commissioner Seaton pointed out grammatical mistakes and Commissioner Tyler asked what prompted staff to make this change. Senior Engineer Steve Speer explained that the Tradition development had a couple of areas that were steeper than the 20% slope that are scarred and the desire is to put golf facilities on these locations. 25. Page 150-8 - Commissioner Tyler asked that under Bed and Breakfast Inns it should read, "One space per guest room plus parking for residence as required by this section. 26. Page 200-7 - Commissioner Tyler asked staff to explain the change. Staff explained that the 20-day noticing requirement is a CEQA requirement. When a project is subject to the California Environmental Quality Act you must provide a 20-day noticing period for environmental determination. Some items are exempt from CEQA and staff is trying to reduce their noticing requirement down to ten days to expedite the processing. 27. There being no further discussion, it was moved and seconded by Commissioners Tyler/Gardner to adopt Planning Commission Resolution 97- 006 recommending approval of Zoning Ordinance Amendment 96-054, with the amendments as discussed. ROLL CALL: AYES: Commissioners Butler, Gardner, Newkirk, Seaton, Tyler, Woodard, and Chairman Abels. NOES: None. ABSENT: None. ABSTAIN: None. VI. BUSINESS ITEMS - None VII. COMMISSIONERS ITEMS. A. Commissioner Seaton informed the Commission that she had attended the Planning Commission Forum in Riverside and found it very informative and stated the issues that were discussed. She thanked the Commission for the opportunity to attend. B. Commission Tyler stated his concern about a newspaper article concerning the lack of school facilities in the northern portion of the City. Although there is nothing the Commission, Council, or staff can do regarding it, it is unfortunate that the situation exists. C. Commissioner Gardner stated he had an occasion to be in Florida the previous week. While looking at an area that had been developed, he traveled numerous times down a street called International Drive. It was his determination that it was most singularly unattractive location he has ever seen. It brought to mind that as Commissioners they each have own idea of what is beautiful. He asked if funds PC 1-28-97 7 Planning Commission Meeting January 28, 1997 could be made available to the Commissioners for transportation to allow the Commission to travel to other cities to see what is being developed in order to avoid this type of thing happening to La Quinta. Chairman Abels stated that this had been discussed at previous meetings and he felt that both the Commission and Council should visit cities that the City could pattern itself after, such as Rancho Cucamonga and Alta Loma. Commissioner Woodard suggested that in order to save on costs, he would suggest inviting the top five residential architects listed in Orange County to make a presentation to the Commission/Council. Orange County has a world of resources for new concepts and information. Chairman Abels stated that from the visual standpoint of actually seeing the areas as to how they have developed would be more beneficial. Commissioner Tyler stated that at last years' League of California Cities Conference a presentation was made regarding this. D. Commissioner Butler stated that he too had read the article regarding the schools in northern La Quinta, and it was his opinion that if there was an impact on a school the Planning Commission should be informed of the potential risk during their review of a project. City Attorney Dawn Honeywell stated the difficulty is with the exception of reviewing General Plan Amendments or legislative decisions, the City is not allowed to take the impact on the school into consideration. Schools have their sole remedy in their mitigation fees and this was put into place by the State. E. Chairman Abels stated he was trying to schedule a joint meeting with City Council. F. Commissioner Tyler gave a report on the Council meeting of January 21, 1997. ADJOURNMENT: There being no further business, it was moved and seconded by Commissioners Gardner/Butler to adjourn this regular meeting of the Planning Commission to a meeting of February 11, 1997. This meeting of the Planning Commission was adjourned at 9:44 P.M. on January 28, 1997.

Although it is the intent of Canaday Construction to build these homes on the balance of the lots at Lake La Quinta, Canaday will be buying and building only eleven homes initially. The balance of the lots cannot be preplotted as Canaday does not own them and accurate plottings will not be available until sale of the first phase. However, we as the Declarant, have required Canaday to comply with our request in providing a minimum of two elevations for each plan and six, previously approved, colors. This, along with the option of guest suites and compatible courtyard walls with landscape packages on all plans, should insure the the street scene will be compatible and ascetically pleasing. Since it is in Wilma's, and, the existing homeowners best interest, Wilma as the Declarant, will make every effort to enforce a continuity of design and plan.

Desert Development_ ENGINEER: Advanced Engineering Group, Inc. REQUES'"r: Approval to subdivide 98 residential lots into 96 residential lots 'with private streets and access into Rancho La Quinta Country Club LOCATION- North and East of the intersection of Sagebrush Avenue and Date Palm Drive (attachment 1) ENVIRONMENTAL CONSIDE'.RATION: The La Quinta Community Development Department has completed Environmental Assessment 97-336. Based upon this assessment, the Community Development Department has determined the Tentative Tract will not have an adverse impact on the environment. Therefore, a mitigated, Negative Declaration has been prepared and is recommended for certification. GENERAL PLAN LANE) USE DESIGNATION: Low Density Residential (2­4 dwellings per acre) ZONING: RL Low Density Residential SURROUNDING ZONING AND LAND USE The site is surrounded by the following zoning and land uses: North-. RL vacant Rancho La Quinta South- FP Evacuation Channel East- RL / vacant Rancho 'La Quinta West: RL / residential Units TRACT HISTORY AND IMPROVEMENTS PCRES-TT28498 The subject property is improved with all utilities and street improvements pursuant to Tentative Tract 25154. The Tract was originally approved in 1989 with development occur�ng several years ago. The 98 lot tract was intended to be a custom lot project, but no homes have constructed to date. PROJECT REQUEST The applicants have purchased the tract from the original developers and intend to construct units for sale. They need to therefore, provide a card gated entry at the traffic entrance at the intersection of Sagebrush Avenue and Date Palm Drive and access into the country club. The gate requires the streets be changed from public to private. This Tentative 'Tract map provides the vehicle to make this change. The map also eliminates one lot in the center of the north boundary for access into the country club. A lot has been combined with the adjacent lot at the Sagebrush Avenue: and Date Palm Drive intersection so that all lots will be within the confines of the gated country club. Therefore, this map creates 96 single family lots rather than the original 98 lots. There are minor lot dimension changes, but the layout Is essentially the same as the existing. Lot depths are approximately ten feet longer due to the street rights -of -way being decreased for the private streets. The Ventanas units, which were approved June, 1996, under Plot Plan 96-584 by the Planning Commission, are proposed to be constructed in this tract. These units consist of three floor plans between 1850 to 2300 square feet of floor area. ENVIRONMENTAL ASSESSMENT The Community Development Department has prepared Environmental Assessment 97-336 and determined that the project will riot have a adverse impact on the environment, and therefore, recommends adoption of a Negative Declaration (attachment 2). This Tentative Tract Majo request was, advertised in the Desert Sun on February 4, 1997, and mailed to all property owners within 500 feet of the tract boundaries. Staff has received a letter from Mr. Charles Lester, a representative of the owner of the properties at the southeast corner of Sagebrush Avenue and Date Palm Drive, adjacent to the subject site. Mr. Lester indicates the proposed entry gate will adversely affect one of his parcels which fronts on Rio Seco (Sagebrush Avenue). He would like to see modification to proposed lot 45, his lot, and the entry gate, which he feels will benefit the applicant and his property (attachment 3). STATEMENT OF ISSUES AND FINDINGS: #1 - Consisteric- ith General Flan and Zoning Code. PCRH-TT28498 The project site is designated on the General Plan Land Use Map as Low Density Residential, allowing 2 to 4 dwelling units per acre. The density of the proposal is approximately 3.5 Dwelling units per acre, within the allowable range of 2 to 4 dwelling units per acre. The zoning of the site is RL (Low Density Residential), which requires a minimum 7,200 square foot lot. The proposed lots exceed this requirement. Issue #2 -- Tract desic gn.) Improvement / Gradinq As noted, the streets and utilities have been installed in the subdivision, with the pads rough graded in conformance with the original Tract 25154. With this proposal, some minor regrading may occur on several of the lots to accommodate the revised lots. Issue #3 - Health and Safety Concerns All infrastructure improvements including water, sewer, streets, and other necessary improvements have been installed. New services have been installed underground and meet the requirements of the utility companies. Any fees due at the time of building permit, will be, paid by the developer. L!gEw—e �� - Environmental Assessment The Community Development Department has prepared Environmental Assessment 97-336 for this prcject. Based on the assessment, staff has concluded the project will not have an adverse impact on -the environment, based on the recommended conditions of approval. STAFF COMMENTS The tract improvements have been Installed with the exception of the entry gate near Sagebrush Avenue and Date Palm Drive, and the entry street at the north property line into Rancho La Quinta. Therefore, there should be no constraints to prevent development of the site as planned. The residences previousIly approved for the applicant and planned to be constructed in this are acceptable and will be compatible with the surrounding neighborhood. CONCLUSION: Findings for a recommendation of approval of this Tentative Tract Map can be made are contained in the attached Resolution. REC, IMMENDATION: Adopt Resolution 97- , recommending to the City Council approval of Environmental Assessment 97-336, for Tentative Tract 28498, and PCRES-T-128498 2.

PREPARED FOR TENTATIVE TRACT 28498 ENVIRONMENTAL ASSESSMENT 97-336 T,D. DESERT DEVELOPMENT WHEREAS, the Planning Commission of the City of La Quinta, California, did on the 25th day of February, 1997, hold a duly noticed Public Hearing to consider Tentative Tract Map 28489; and, WHEREAS, said application has complied with the requirements of "The Rules to Implement the California Environmental Quality Act of 1970" (as amended; Resolution 83-68 adopted by the La Quinta City Council) in that the Community Development Department has prepared an Initial Study (EA 97-336); and WHEREAS, the Community Development Director has determined that said Tentative Tract will not have a significant adverse effect on the environment and that a Negative Declaration of Environmental Impact should be filed; and WHEREAS, upon hearing and considering all testimony and arguments, if any, of all interested persons desiring to be heard, said Planning Commission did find the following facts, findings, and reasons to justify recommending certification of said Environmental Assessment: 1. The proposed Tentative Tract will not be detrimental to the health, safety, or general welfare of the community, either directly or indirectly, in that no significant impacts have been identified, and less than significant impacts can be addressed by adherence to standard City development requirements. 2. The proposed Tentative Tract will not have the potential to degrade the quality of the environment, as the project in question will not be developed in any manner inconsistent with the General Plan, Zoning and other current City standards. The project does not have any potential to eliminate any important example of California prehistory, as the site was previously disturbed several years ago in conjunction with mass grading and improvement installations under the previous approval for Tract 25154. earesopc.336 Planning Commission Resolution 97- 3. The proposed Tentative Tract does not have the potential to achieve short-term environmental goals, to the disadvantage of long-term environmental goals, as the proposed project will not significantly alter the type or intensity of the residential use already approved and contemplated in the General Plan for the site, and for which infrastructure improvements have already been completed. 4. The proposed Tentative Tract will not have impacts which are individually limited but cumulatively considerable when considering planned or proposed development in the immediate vicinity, in that the proposed project, whether approved or not, is a consistent representation of the project type already approved and physically implemented for the site as long as the current General Plan land use and zoning designations are applicable. 5. The proposed Tentative Tract will not have environmental effects that will adversely affect the human population, either directly or indirectly, as the project contemplates residential use identical in spirit to that already assessed under ultimate development of the La Quinta General Plan, and incorporated with the EIR previously certified in 1992 for the General Plan. NOW, THEREFORE, BE IT RESOLVED by the Planning Commission of the City of La Quinta, California as follows: 1. That the recitations are true and correct and constitute the findings of the Planning Commission for this Environmental Assessment. 2. That it does hereby recommend certification of Environmental Assessment 97- 336 for the reasons set forth in this Resolution and as stated in the Environmental Assessment Checklist and Addendum, attached hereto, and on file in the Community Development Department.

A Lead Agency is the public agency which has the principal responsibility for carrying out or approving a project which may have a significant effect upon the environment. The City of La Quetta, as the Lead Agency, has the authority to oversee the environmental review and to make a decision on the proposal. 1.2 PURPOSE OF THE INITIAL STUDY As part of the environmental review for the proposed tract map, the City of La Quinta Community Development Department has prepared this Initial Study. This document provides a basis for determining the nature and scope of any subsequent environmental review for this proposal. The purposes of the Initial Study, as stated in Section 15063 of the CEQA Guidelines, include the following: To provide the City with information to use as the basis for deciding whether to prepare an environmental impact report (EIR) or a negative declaration for a project; To enable the applicant or the City of La Quinta to modify the project, mitigating adverse impacts before an EIR is prepared, thereby enabling the project to qualify for a mitigated negative declaration of environmental impact; To assist in the preparation of an EIR, should one be required, by focusing the analysis on those issues that will be adversely impacted by the proposed project, To facilitate environmental review early in the design of the project, To provide documentation for the findings in a negative declaration that the project will not have a significant effect on the environment. To eliminate unnecessary EIR's; and To determine whether a previously prepared EIR could be used with the project. 1.3 BACKGROUND OF ENVIRONMENTAL REVIEW The proposed subdivision was deemed subject to the environmental review requirements of CEQA in light of the potential project impacts associated with the project scope. The Environmental Officer for the Community Development Department prepared this Initial Study and addendum for review and certification by the Planning Commission and City Council for the City of La Quinta. EA97336.wpd rd 1.4 SUMMARY OF PRELIMINARY ENVIRONMENTAL ASSESSMENT This Initial Study checklist indicates no potential for significant environmental impacts. As a result, no specific mitigation measures have been incorporated, and a Negative Declaration of Environmental Impact can be recommended for this project. Any changes made by the applicant to the project as a result of this assessment, design review or other reason, which would necessitate changes to this addendum, are shown in italics as part of the issue area which any such changes may affect. SECTION 2° PROJECT DESCRIPTION 2.1 PROJECT LOCATION AND ENVIRONMENTAL SETTING The City of La Quinta is a 31.18 square mile municipality located in the southwestern portion of the Coachella Valley. The City is bounded on the west by the City of Indian Wells, on the east by the City of Indio and Riverside County, on the north by Riverside County, and federal and county lands to the south. The City of La Quinta was incorporated in May, 1982. The proposed project consists of approximately 27.2 acres, immediately east of tract 21555 (Parc La Quinta), between the La Quinta Evacuation Channel and the southwesterly boundaries of the Rancho La Quinta Specific Plan. The applicants have submitted a tentative tract application (TT 28498). The site was previously graded in conjunction with approval of TT 21545 several years ago, and is flat with minimal vegetation. Most improvements, including curb and gutter, have been constructed on the site. The site drains into the La Quinta Evacuation Channel on its southeasterly boundary. 2.2 PHYSICAL CHARACTERISTICS The subdivision proposes to reduce the existing tract's current lot count to 96 and create a private street system, with a gated access at the current Sagebrush Avenue access and an internal project access at the north tract boundary. The current lot and street patterns and dimensions would essentially remain as configured, since road and utility improvements exist on the site. 2.3 OPERATIONAL CHARACTERISTICS The property is designated LDR (Low Density Residential, 2-4 units/acre), and zoned RL (Low Density Residential). These designations are nearly identical to those in effect when the original tract 25154 was approved in 1989; the Zoning Code was updated and revised in 1996. There is no proposed change to density or unit type proposed for this subdivision. 2.4 OBJECTIVES To create a community with private streets and access to the Rancho La Quinta Country Club. 2.5 DISCRETIONARY ACTIONS A discretionary action is an action taken by a government agency (for this project, the government agency is KA97336.wpd the City of La Quinta) that calls for the exercise of judgment in deciding whether to approve a project. The proposed subdivision will require discretionary approval from the Planning Commission and City Council for the following: • Certification of the Environmental Assessment for the project; • Approval of a Tentative Tract Map. 2.6 RELATED PROJECTS There are no related projects to this proposal under review at present. SECTION 3• ENVIRONMENTAL ANALYSIS This section analyzes potential environmental impacts associated with the proposed project. CEQA issue areas are evaluated in this addendum as explained in the Initial Study Checklist. Under each checklist item, the environmental setting is discussed, including a description of conditions as the presently exist within the City and the areas affected by the proposed project. Thresholds for significance are defined either by standards adopted by responsible or trustee agencies or by referring to criteria in CEQA, Appendix G. 3.1 LAND USE AND PLANNING Regional Environmental Setting The City of La Quinta is located in the Coachella Valley, in the eastern portion of Riverside County. Topographic relief ranges from 237 feet below mean sea level (msl) to about 2,000 feet above msl. The Valley is surrounded by the San Jacinto Mountains, the Santa Rosa Mountains, the Orocopia Mountains, and the San Bernardino Mountain Range. The San Andreas fault transects the northeastern edge of the Valley. Local Environmental Setting The subject site is vacant. The project use as proposed is consistent with the General Plan and zoning currently in effect, as well as with the current recorded subdivision. A through D - No Impact. The project does not propose uses inconsistent with the current or future land uses contemplated for the project area. All properties bordering the site are designated for residential use. The proposal will have no conflicts with any environmental policies or plans in effect which would apply to the project. There are no agriculture resources or operations, or established residential communities which could be adversely affected by the project. 3.2 POPULATION AND HOUSING Regional Environmental Setting The City's population as of January, 1996 is estimated by the State Department of Finance to be 18,046 persons. In addition to permanent residents, the City has approximately 9,300 seasonal residents who spend three to six months in the City (WDL Economic Overview, 1996 Ed.). It is estimated that 30% of all housing units in the City are used by seasonal residents. The average occupancy is 2.85 persons per occupied unit (1990 Census). EA97336.wpd 701 Local Environmental Setting The site is designated Low Density Residential (LDR, 2-4 units/acre) on the City's General Plan Land Use Policy Diagram. The areas surrounding the project are similarly designated; an existing subdivided area to the southwest of the site is designated Medium Density Residential (MDR, 4-8 units/acre). A through C - No Impact. Development of the project site as proposed is consistent with the land use designation set forth in the La Quinta General Plan. The proposal itself will not exceed any current growth forecasts currently available to or used by the City, as the previously approved tract was considered in those forecasts, nor will it cause any change in anticipated growth patterns or numbers, based on the build out scenarios in the General Plan. No effects on affordable housing are anticipated due to development of this project. 3.3 EARTH RESOURCES Regional Environmental Setting The City of La Quinta has a varied topography, from gently sloping alluvial fans, steep hillside, to relatively flat desert floor. The alluvial soils that make up most of the City's soil types are underlain by igneous - metamorphic rock, as seen in outcrops in the Santa Rosa Mountains and the Coral Reef Mountains. Soils on the Valley floor are made up of very fine grain unconsolidated silty sands. Local Environmental.S'etting The site consists of Myoma Series soils, which are characterized by rapid permeability and commonly used for home sites and other urban uses. While it can be used in development of croplands, it is not considered as prime agricultural soil as classified by the State. The soil on this site is influenced by it's proximity to the La Quinta Evacuation Channel. The site is located within a Ground shaking Zone 3. referenced as a minimal level of shaking activity. There are no active faults in the area (LQMEA). A through I - No Impact. The project should not present significant exposure to geologic hazards associated with fault rupture, as no inferred fault traces are identified proximate to the site. The existing physical conditions in the area will not be changed in a manner which would create any impacts beyond those associated with development of the site in accordance with the General Plan. The project is located in a Ground shaking Zone 3, associated with minimal impacts from seismic activity. Impacts involving potential seismic activity also relate to possible risk associated with building failure and collapse, though by definition this would not be experienced in Zone 3. The project will adhere to seismic reinforcement and other requirements as called for in the UBC. The site is identified as susceptible to minimal ground shaking impact, and soil characteristics indicate that ground failure due to such activity is negligible, based on its use in urbanized development. The site is not identified as subject to liquefaction potential, and there is no potential for seiche, tsunami or volcanic activity. The site is level and not subject to slide or mudflow impacts. The Whitewater Channel does not affect the property during drainage flows (LQMEA: site history). There will be little to no change in surface features due to project grading. The site has been graded and improved with localized infrastructure improvements, only minor finis grading for individual house pad requirements remains to be done. Soil erosion potential will be affected due to loosening and movement of soil material during such grading, the site is also subject to wind erosion. Standard erosion control and soil EA97336.wpd management methods as identified in soil reports and addressed in grading plans required for the site will ensure that such impacts will not be significant. Submittal of a dust control plan as required (see Air Quality) to address wind erosion reduction in the interim period prior to actual development will be required. The site is not identified as being subject to subsidence or having soils which are expansive. There are no unique geologic or physical features on the site with respect to Earth issues (LQMEA. site survey). 3.4 WATER Regional Environmental Setting Groundwater resources in the La Quinta area consist of a system of large aquifers (porous layer of rock material) and groundwater basins separated by bedrock or layers of soil that trap or retain groundwater. Water supplies are also augmented with surface water from the Colorado River transported via the Coachella Canal and stored at Lake Cahuilla. Percolation from the tributaries of the Whitewater River flowing into La Quinta from the Santa Rosa Mountains provide a natural source of groundwater replenishment. Artificial recharging of groundwater will be a requirement in the near future. Local Environmental Setting The vicinity of the proposed project is protected from design storms by the Whitewater Channel flood control facility and other improvements. The site is mostly level and incorporates well drained soils. The site is designated Zone X on the federal Flood Insurance Rate Maps in effect for the area, outside of the 500 year flood limits, and is generally surrounded by lands outside of the 500 year flood limits on all sides (FIRM dated 8/19/91: CPN 060709-0005A). A through H - No Impact. Current runoff rates will be increased due to building and hardscape area development. The runoff produced by development of this site is required to be retained on -site. The project will be required to prepare a final drainage plan and comply with NPDES permit requirements as enforced by the Public Works Department. The area is currently protected from flood impacts by existing flood control facilities, specifically the Whitewater and La Quinta Evacuation Channels. No surface wagers or other streams exist which could be affected, and ground water resource quantity and quality will not be directly impacted. Compliance with NPDES requirements attached to the project permitting will ensure that storm water runoff associated with the remaining project development will not create any measurable impact to water quality, quantity or hazards. 3.5 AIR QUALITY Regional Environmental Setting The Coachella Valley is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD), and is located in the Southeast Desert Air Basin (SEDAB). SEDAB has a distinctly different air pollution problem than the South Coast Air Basin (SOCAB). Currently, the SEDAB does not meet federal standards for ozone, carbon monoxide, or particulate matter. Local Environmental Setting The City is located in the Coachella Valley, which has an and climate, characterized by hot summers, mild EA97336.wpd winters, infrequent and low annual rainfall, and low humidity. Variations in rainfall, temperatures, and localized winds occur throughout the Valley due to the presence of the surrounding mountains. Air quality conditions are closely tied to the prevailing winds of the region. In the Coachella Valley, the standards for PM 10 are frequently exceeded. PM 10 is particulate matter 10 microns or less in diameter that become suspended in the air primarily due to winds, grading activity, and by vehicles on unpaved roads. The Valley is currently designated by the EPA as a serious non -attainment area for PM 10, however SCAQMD anticipates that recent data will show that the Valley has been in attainment over the last three years. Based on this. SCAQMD is in the process of preparing a PM 10 Maintenance Plan in order to have the area redesignated to attainment status. A - Less Than Significant Impact. Based on the SCAQMD CEQA Air Quality Handbook, the project is not anticipated to create any significant air quality impact. The ITE Trip Generation Manual, 4th Edition , indicates that ADT for the project is estimated at 960, based on the project lot count of 96. This indicates a negligible impact to air quality from ultimate operation of the project. However, short term (construction - related) impacts will result primarily from grading activities, which will generate fugitive dust. Prior to any soil disturbance or grading activity(ics) the devcloper shall secure approval of a Fugitive Dust Control Plan (FDCP) The plan shall address interim measures for all proposed development areas as well as those areas which may be disturbed by activity but scheduled for later development The FDCP shall be submitted within 30 days of City Council approval of Tentative '][Tact 28498 Interim measures to address existing wind erosion conditions on the site shall be implemented within 10 days of plan approval by the City. This plan shall also address and clearing, grading, or other site activit)� request which will disturb or is otherwise related to development of the site. B through D - No Impact. The proposed project will not expose sensitive receptors to pollutants. The La Quinta Middle School site is the nearest non-residential sensitive receptor, and is located across the La Quinta Evacuation Channel from the site. Residential receptor areas surround the site, which itself will be a sensitive receptor upon development of the single family lots. Construction -related air quality impacts will occur primarily from grading activities and other soil disturbances. The required FDCP will address these short-term construction impacts. Long term impacts from roadway emissions due to cumulative impacts of growth in accordance with the La Quinta General Plan were considered in the EIR document. The project has no potential to effect any climatological change, and negligible potential to create objectionable odors. 3.6 TRANSPORTATION/CIRCULATION Regional Environmental. Vetting The existing circulation system is a combination of early roadwork constructed by Riverside County and new or resurfaced roads since incorporation of the City in 1982. Key roadways in the City network include State Highway 111, Washington Street, Jefferson Street, Fred Waring Drive, and 50th Avenue. Traffic volumes in La Quinta experience seasonal variation. late winter/early spring months represent the peak tourist season. Local Environmental.Setting The site is directly behind the existing Parc La Quinta subdivision (Tract 21555), to the east, and incorporates an improved local street network serving all 98 existing lots. The site is accessed via Sagebrush Drive from the west, which terminates as it enters the site and becomes the collector loop in the project's street network. A through G - No Impact. The project will unquestionably create increased trips and congestion; however. the minimal, street traffic anticipated on the local area network will not be significant. In addition, the gating of the current access and provision of the main access into the Rancho La Quinta project area will further EA97336.wpd DE reduce the number of project -related trips. The applicant will be requi red to dedicate and install any additional improvements deemed necessary by the Public Works Department in accordance with the conditions of approval for the project and any development agreement(s). The project is not anticipated to create design -related hazards or any type of inadequate access situation. Traffic safety improvements as typically required of new development will also provide reductions in traffic hazard impacts, commensurate with development of the site, and should improve the overall safety level of the roadways in general. Parking for the individual units will be required to be provided on each individual lot. additional on -street parking will also be available. There will no potential for insufficient parking to be available. The project is not required to provide for alternative transportation infrastructure, and is not proximate to, nor is it affected by, water, air or rail traffic. 3.7 BIOLOGICAL RESOURCES Regional Environmental.Setting The City of La Quinta lies within the Colorado Desert. Two ecosystems are found within the City, the Sonoran Desert Scrub and the Desert Transition. The disturbed environments within the City are classified as urban or agricultural. A discussion of these ecosystems is found in the LQMEA. Local Environmental Setting The subject area is considered as vacant infill residential with developed infrastructure, with level terrain and minimavegetation due to previous mass grading associated with the infrastructure development for the site. There are no riparian/wetland habitats or streambeds on the site. The LQMEA identifies the entire site as within the Coachella Valley Fringe -Toed Lizard habitat area, for which a federal l0A permit was obtained pursuant to adoption of the CVFTL Habitat Conservation Plan (HCP). The required fee was paid for the entire site as part of the mass grading permit on June 18, 1990 (Grading permit G702). A through E - No Impact. There is negligible potential for wildlife habitat to exist on the site due to the previous disturbances and existing conditions. Mitigation fees -For the CVFTL were previously paid in conjunction with grading permits issued for the site. There are no tree stands or other significant vegetation on the site. No wetland areas traverse the site, and the location of the site adjacent to the La Quinta Evacuation Channel and two residential projects precludes any potential migration of wildlife. 3.8 ENERGY AND MINERAL RESOURCES Regional Environmental Setting La Quinta contains both areas of insignificant and significant Mineral Aggregate Resources Areas (SMARA). as designated by the State Department of Conservation. There are no known oil resources in the City. Energy resources used in the City come from the Imperial Irrigation District and Southern California Gas Company. Local Environmental.Setting The site does not lie within an identified area sensitive to mineral resources. Soils within the site consist of Myoma fine sand, these soils are well -drained and permeable, and are suitable for residential and agricultural uses. The site has been previously prepared for residential development. P' A97336.wpd A, B - No Impact. The proposed project has no potential to impact energy or mineral resources in any manner which could be considered wasteful. Construction of the project's residential units will be required to meet State energy standards as typically enforced by the Building and Safety Department, and to comply with energy conservation policies as established in the La Quinta General Plan. 3.9 RISK OF UPSET/HUMAN HEALTH Regional Environmental Setting Although large scale, hazardous waste generating employment is not yet located within La Quinta, the existence of chemicals utilized in dry cleaning operations, agricultural operations, restaurant kitchen cleaning, landscape irrigation and exposure to large scale electrical facilities may post significant threats to various sectors of the population. Currently, there are no hazardous disposal waste sites located in Riverside County: transportation of such materials out of and through La Quinta takes place. Local Environmental.4etting The project site is vacant residential and has not been used for any type of manufacturing in the past. A through E - No Impact. There is practically no potential risk of explosion and/or release of hazardous substances due to the project. The on -site storage of certain amounts of chemical compounds in various packaging, and other potentially hazardous materials could occur as would commonly be found in individual homes, and in conjunction with a home occupation (fertilizers, home pesticides, pool chemicals, etc.). Storage of potentially hazardous products are regulated by State and Federal legislation, and will also be subject to Fire and Health Department standards as in effect and applicable at the time. The project does not have any potential to interfere with emergency response or create any health hazards. The site is not in an area susceptible to increased fire hazards relative to brush, grass or trees, as minimal or no susceptible vegetation exists in the immediate area. 3.10 NOISE Regional Environmental Setting Noise levels in the City are created by a variety of sources in and near the City. The major sources include vehicular noise on City streets and Highway 111, and temporary construction noises. The ambient noise levels arc dominated by vehicular noise along the Highway and major arterials, but can be impacted by aircraft noise from Bermuda Dunes, usually of a short duration. Local Environmental Setting Primary noise sources in the subject area are associated with vehicle traffic and the adjacent middle school site. The property is vacant and therefore not a current source of noise, although the developed street system on -site does accommodate some vehicle traffic. The site is currently impacted by construction activities at the Rancho La Quinta Country Club, associated with continuing residential development. The project is intended to facilitate incorporation of the existing site area and improvements into the existing Rancho La Quinta development. A, B - No Impact. Increases in noise levels are anticipated due to the proposal, though not expected to be significant. Roadway noise will increase as traffic volumes increase. The majority of the traffic volume in this area is expected to relate directly to this project. It is not anticipated that the additional volumes (i.e., 960 ADT estimated) attributable to this site's development will create any significant increases in noise levels in the area, EA97336.wpd and are not expected to impact existing land uses in the immediate area. The proposed residential use is not considered as typically being a source of extreme or severe noise levels to surrounding uses. 3.11 PUBLIC SERVICES Regional Environmental Setting Law enforcement services are provided to the City through a contract with the Riverside County Sheriff's Department. Fire protection service is provided to the City by Riverside County Fire Department. The Fire Department administers two stations in the City, Station #32 on Frances Hack Lane, and Station #70. at the intersection of Madison Street and Avenue 54. Paramedic services are provided by Springs Ambulance Service. Health care services are provided in the City through JFK Memorial Hospital in Indio, and the Eisenhower Immediate Care Clinic located in the One -Eleven La Quinta Shopping Center. Local Environmental Setting Riverside County Fire Station #32 and Station 470 are located approximately 1 '/2 miles south and 4 miles souteast, respectively, of the project site, Station #31 is located in Bermuda Dunes on 42nd Avenue and Adams Street, approximately 3 1/2 miles north of the project site. The Sheriff's office maintains a check -in facility in the City's EOC. Other governmental services in La Quinta are provided by City staff at the Civic Center. A through E - No Impact. The project will not impact public services, based upon the comments received. All necessary public services can be provided to the project without compromising any existing levels of public service. The proponents will have to pay school fees as established by Desert Sands Unified School District upon application for residential building permits. 3.12 UTILITIES Regional Environmental Setting The City of La Quinta is served by the Imperial Irrigation District (IID) for electrical power supply and the Southern California Gas Company (SCG) for natural gas service. General Telephone Exchange (GTE) provides telephone services for the City. Continental Cablevision services the area for cable television service The Coachella Vallev Water District (CVWD) provides water and sewer service to the City. CVWD obtains its water from underground aquifers and from the Colorado River. The City's stormwater drainage system is administered by CVWD, which maintains and operates a comprehensive system to collect and transport flows through the City. The City is served by Waste Management of the Desert for so'.id waste disposal. Nonhazardous, mixed municipal solid waste is taken to three landfills within the Coachella Valley. Local Environmental. Setting The subject site has been developed with the necessary infrastructure at present. Street and flood control improvements have been completed. along with sewer and water line extensions being in place, however, some utility trunk extensions and connections will be necessary to develop the property. A through F - No Impact. The proposed project will require some degree of alteration to existing facilities. however, the responses received from the responsible purveyors do not present any significant concerns to indicate that major new systems or retrofitting will be necessary to serve the project. EA973 36.wpd 12 3.13 AESTHETICS Local Environmental .Setting The City of La Quinta is partially located within a desert valley cove. There are hillsides to the west and south of the City. Views of the desert and surrounding mountains are visible on clear days throughout most of the City. Views of the Santa Rosa and Coral Reef Mountains exist to the south, east and west of the site. A through C - No Impact. The project will have limited impact on scenic vistas, as there are no applicable scenic viewsheds identified in the LQMEA. The height of any proposed structures may block some view lines, but the impact will be minimized through design review of the proposed residential units via the compatibility process. As with any project, the proposal will create additional light and glare. The City has an adopted "Dark Sky" ordinance which regulates lighting types and shielding characteristics. However, the types of lighting commonly associated with individual residences is generally exempt from those requirements. Street lighting, if proposed, would be required to comply with the ordinance. Overall, the design of the project should not have any demonstrable negative aesthetic effects, provided that the above identified issues are addressed. 3.14 CULTURAL RESOURCES Regional Environmental. Vetting The most likely locations of prehistoric cultural resources in the La Quinta area are along the foothills. The settling of the La Quinta area has been chronicled by the La Quinta Historical Society in several publications and museum exhibits. There are 13 designated historical structures and sites recorded on the California Historic Resources Inventory. These resources are listed in the La Quinta General Plan. Local Environmental.Velting No historic structures exist in the immediate area. The site is generally barren of any significant vegetation. A cultural resource assessment ( CRA) was required prior to grading of the site in 1990. As the project grading and improvements have already been completed, any potential archaeological resources would have been determined previously and could not be affected by build out of the residential lots A Through E - No historic resources exist on the site. Remaining development of the project has no potential to affect any cultural values, and no existing religious uses are associated with the site. 3.15 RECREATION Local Environmental &tting The City of La Quinta has an adopted Parks and Recreation Master Plan that assesses existing resources and facilities for future needs of the City. The City has approximately 28.7 acres of developed parkland for Quimby Act purposes. There are also designated bike paths, equestrian and pedestrian trails within the City. A, B - No Impact. The proposed project will not significantly affect demand for recreational facilities or existing recreation. While the project will attract additional customer base from within La Quinta and other communities, it is not likely that the project will attract a significant number of new residents. Quimby Act fees were previously paid for this site with recording of Tract 25154. I;A97336.wpd 13 SECTION 4: MANDATORY FINDINGS OF SIGNIFICANCE The Initial Study for this project did not identify any potentially significant impacts. The following findings can be made regarding the mandatory findings of significance set forth in Section 15065 of the CEQA Guidelines and based on the results of this environmental assessment: a) The proposed Tentative Tract Map will not have the potential to degrade the quality of the environment, as the project in question will not be developed in any manner inconsistent with the General Plan and other current City standards. The project has already been developed with infrastructure improvements required by the General Plan and implementation standards at time of their development. b) The proposed Tentative Tract Map will not have the potential to achieve short term goals, to the disadvantage of long-term environmental goals, as the proposed project will not significantly alter the type or intensity of the residential use already contemplated in the General Plan and currently approved for this site. c) The proposed Tentative Tract Map will not have impacts which are individually limited but cumulatively considerable when considering planned or proposed development in the immediate vicinity, in that the proposed project is a consistent representation of the project type envisioned and currently approved for the site, under the current General Plan land use and zoning designations. d) The proposed Tentative Tract Map will not have environmental effects that will adversely affect humans, either directly or indirectly, as the project contemplates uses identical in type and intensity to those already assessed under ultimate development of the La Quinta General Plan, and which were addressed in the EIR previously certified for the General Plan and in Environmental Assessment 89-144 prepared for Tentative Tract 25154. SECTION 5: EARLIER ANALYSES A. Earlier Analyses Used. The following documents were used and/or referred to in the preparation of this assessment: • La Quinta General Plan Update: October 1992 • La Quinta Master Environmental Assessment; October 1992 • SCAQMD CEQA Air Quality Handbook, April 1993 • Environmental Assessment 89-144, Tract 25154, prepared October, 1989 • ITE Trip Generation Handbook, 4th Edition, 1987 These and various other documents on file with the Community Development Department were used in the preparation of this Initial Study. B. Impacts Adequately Addressed. No potentially significant impacts were identified in the checklist, therefore no impacts have been determined to exist which require mitigation. C. Mitigation Measures. Mitigation measures were not deemed necessary for this proposal beyond EA97336.wpd standard requirements incorporated into all permit approvals, both discretionary and ministerial.

RE: TENTATIVE TRACT 28498 Ladies and Gentlemen: (619) 360-1399 Fax: same - r �7 �)EPARTMEN.1 , I am the representative of the owner of properties at the South -East corner of Sagebrush Ave. and Date Palm Dr. We are strongly opposed to the plan for privatising these streets. We are not opposed to the streets becoming private, but we do object to the planned card gates which will adve-sely impact one of our parcels. A copy of the present plan is enclosed. Also en- closed is our suggested solution to the gate question. As now proposed, your applicant is changing the sub- division of 98 lots into 96 lots. I can see where one lot was lost through merger of two former lots at the north of the proposed gates (used to be lots 1 and 2 as shown on my map), but I don't know where the other lot was lost. At any rate, what I would propose is that applicants lot 45 be squared off by me giving applicant a trian- gular piece of land in exchange for applicant giving me an approximate like amount of land. In doing this, aoplicant gains a lot because what is shown as lot 1, where the proposed gate is to be, will be divided into two lots - just as originally subdivided (see my map). Our remainder lot would now be divided into two lots shown as lots 1 and 2 on the south side of Sage- brush (see my map). The gates would now be located at the lot line be- tween lots 3 & 2, extending north, across Sagebrush, to the lot at the north of Sagebrush. Or, alternately, at the line between lots 2 & 1, extending north, accross Sagebrush, to the lot at the north of Sagebrush. Should we end up with one or two lots within the gated community we have already agreed with applicant gnat our lot/s shall be subject to all C.C.&R's of applicant and that any building constructed on our lot/s shall conform to whatever architectural rules that govern applicant. By revising the plan, as I have suggested, every- one wins. Applicant gains a lot, we gain a lot, the resulting lots are of a shape allowing normal con- struction and the gates do not unreasonably interfere with access to any property. Please notify me should you require additional in- formation or explaination. Sincerely, Charles E.

The Coachella Valley Mountains Conservancy was created by the state legislature, effective January 1, 1991, and became a state agency effective January 1, 1997, for the purpose of acquiring and holding, in perpetual open space, mountainous lands surrounding the Coachella Valley, and to provide for the public's enjoyment of, and the enhancement of their recreational and educational experiences on, those lands in a manner consistent Nvith the protection of these lands and their open space, environmental, anthropological, cultural, scientific, educational, recreational, scenic, and N%ildlife resource values, The Consenaney is directed by a 20-member Governing Board, including representatives of seven Coachella Valley cities, two County Supervisors, the Resources Agency, the Wildlife Conservation Board, the Califomia Department of Fish and Game, the California Department of Parks and Recreation, the University of California, the Bureau of Land Management, the U.S. Forest Service, the Tribal Chairman of the Agua Caliente Band of Cahuilla Indians, and three citizen appointees. Issues which the Conservancy believes should be addressed in preparing the Environmental Assessment are: P.O• BOX 2855 • Palm Desert.

If it is deterramed that there is a potential for impacts, an EIR or Focused EIR should be prepared pursuantto CEQA Guidelines Section 15065 which requires mandatory findings of significance if a project has the potential to "reduce the number or restrict the range of a rare or. endangered plant or animal." The peninsular bighorn sheep is a state Threatened species. If required, mitigation measures which should be considered in the EIR include compensation for habitat loss through acquisition of replacement habitat, and control measures to prevent indirect impacts to the sheep. Measures could include avoiding the use of non-native landscape plants, fencing, and avoidance of the use of pesticides and herbicides. An EIR should include consultation with state and federal resource agencies regarding appropriate measures to avoid or minimize impacts to the sheep and regarding appropriate mitigation measures. 2_ Potential impacts to other biota and to scenic resources from the potential introduction of exotic or non-native species. Measures could include prohibiting the use of non -naive landscape plants, and avoidance of the use of pesticides and herbicides, and dedication of the undisturbed mountainous portions of the site to an appropriate conservation agency, or granting a cQnsrvation easement on those lands to such an agency. The Conservancy also encourages the City to use the interim project review process set up under the Memorandum of Understanding for the preparation of the Coachella Valley Multiple Species Habitat Conservation flan (CV1vISHCP). The interim project review process entails consultation with the California Department of Fish and Game and the U.S. Fish and Wildlife Service at the earliest possible stage of project. Consultation beforc the preparation of a Negative Declaration or an EIR would be especially useful to ensure that all biological resource issues and potential mitigation measures, including project redesign, are addressed.

LOCATION: SOUTHERN TERMINUS OF WASHINGTON STREET, EAST OF AVE. BERMUDAS (ATTACHMENT 1) 1 APPLICANT: TRADITION CLUB ASSOCIATES, LLC REPRESENT- ATIVE: MIKE ROWE, WINCHESTER DEVELOPMENT PROPERTY OWNER: BRUCE NIMMER ENVIRONMENTAL CONSIDERATION: THE COMMUNITY DEVELOPMENT DEPARTMENT HAS COMPLETED ENVIRONMENTAL ASSESSMENT 96-333 FOR THE PROPOSED PROJECT. BASED UPON THIS ASSESSMENT, THE PROJECT COULD HAVE AN EFFECT UPON THE ENVIRONMENT, UNLESS MITIGATION MEASURES ARE CARRIED OUT WHICH LESSEN THE IMPACTS TO AN INSIGNIFICNT LEVEL. THEREFORE, A MITIGATED NEGATIVE DECLARATION OF ENVIRONMENTAL IMPACT HAS BEEN PREPARED FOR CERTIFICATION. ZONING DESIGNATION: RL (LOW DENSITY RESIDENTIAL), FP (FLOOD PLAIN), OS (OPEN SPACE) GENERALPLAN DESIGNATION: LDR (LOW DENSITY RESIDENTIAL), W (WATERCOURSE/ FLOOD CONTROL), OS (OPEN SPACE) BACKGROUND: Site Background The proposed project site is a 746.6 acre estate property that has been in private ownership since 1902. It is located at the southern terminus of Washington Street, east of Avenida Bermudas. The property is partially in the Coral Reef Mountains and partially on a sloping alluvial fan on the east side of the Cove. Historically, the property has been a date and citrus ranch, with other crops also grown in the early years after 1902. John Marshall originally purchased the property from the Southern Pacific Railroad and began a farming and ranching operation. A small adobe structure and out buildings were the first buildings constructed on the property. In the 1930's a large house was built that came to be known as the Hacienda Del Gato. Accessory structures (caretakers unit, equipment sheds) were also built. After a succession of owners, the property eventually was purchased for development into a resort country club. Currently, the property is partially developed and partially vacant (Attachment 2). The first of four development applications for the project site was in 1984, when the Crystal Canyon Country Club was proposed. This project consisted of 672 condominium units, 52 single family lots, an 18-hole golf course, and tennis club on 360 acres under Tentative Tract 20328. The project was amended in 1985 to include 843 condominium units and 47 single family lots on 417 acres. In 1986, the Heritage Club was approved for 330 single family lots and an 18 hole golf course on 731 acres. This project expired in 1991. The third project was approved in 1993, and known as the Traditions at La Quinta. This project was to include 399 single family homes, an 18 hole golf course, and tennis complex. The property was placed in the control of the Resolution Trust Corporation and subsequently sold. The fourth, and current, proposed project consists of a lower density private country club around an 18-hole golf course designed by Arnold Palmer. All residential development will be single family homesites for custom home construction. No multiple family units are proposed for this project. Project Request The Tradition Club Associates, LLC, made application to the City on October 15, 1996, for approval of a 241 single family lot country club development to be called the Tradition Club. The residential lots will provide custom homesites around an 18-hole golf course. The Hacienda del Gato will be rehabilitated to serve as administrative and sales offices for the country club. A new clubhouse, cart barn, maintenance building, half -way house, and main entry gatehouse are proposed to serve the club residents. The development will be gated and have a main entry off of Washington Street. The golf course will feature five lakes interspersed throughout the golf course. The internal streets will be private. Perimeter landscaping and a masonry wall will enclose the project along Avenida Bermudas and Avenue 52. The applicant is proposing a high -end project with many design amenities. The golf course has been designed by Arnold Palmer. Change of Zone In order to permit the approval of the proposed project, a change of zoning designation for a portion of the proposed golf course is necessary. Golf courses are permitted in the GC (Golf Course) Zoning District. They are also a permitted use within the FP (Flood Plain) Zoning District. The proposed golf course will utilize a portion of the existing flood control retention basin on the property. However, those proposed golf course areas that are not within the FP Zoning District must have a designation change to the GC Zoning District. Thus, the applicant has submitted a request for a zone change from the existing RL to GC as per the exhibit in Attachment 3. Chapter 9.220 of the Zoning Ordinance requires that certain findings be made by the City Council prior to approval of any zone change. These findings are: 0 0 ? 3 1. Consistency with General Pan - that the zone change is consistent with the goals, objectives, and policies of the General Plan. Staff has determined that the change of zone is consistent with the goals and policies of the General Plan in that golf courses are compatible uses within single family country club developments as demonstrated by existing developments of this type. 2. Public Welfare - that the zone change will not create conditions materially detrimental to the public health, safety, and general welfare. Staff has determined that there are no identifiable adverse impacts from the change of zone for a portion of the proposed golf course on the public health, safety, or welfare, as golf courses are generally considered a safe recreational facility. 3. Land Use Compatibility - that the new zoning is compatible with the zoning on adjacent properties. Staff has determined that the proposed zone change is compatible with the surrounding zoning, which is residential, Mood plain, and open space (within the proposed development), and residential, parks and recreation, and village commercial for those adjacent properties. 4. Property suitability - that the new zoning i-s suitable and appropriate for the subject property. Staff has determined that the proposed zoning is suitable and appropriate for the project site as the property is a large estate that has been "ear -marked" for private country club development for over 13 years. The Coral Reef Mountains provide an appropriate backdrop for a country club. The low density residential project with the 18 hole golf course will result in a lower urban impact at the point of contact with the mountainous open space environment. 5. Change in circumstances - that the zone change is warranted because the situation and the general conditions of the property have substantially changed since the existing zoning was imposed. The GC (Golf Course Zoning District was created for the purpose of permitting golf courses. Because the project site does not have the GC Zoning District, it is necessary to change some of the RL (Low Density Residential) Zoning District to GC to accommodate the proposed golf course. 4 ()t1'I Tentative Tract Map The proposed tentative tract map wraps around the edge of the Coral Reef Mountains with either residential lots or golf course abutting the mountains. The tentative tract map (Attachment 4) consists of 241 single family lots, private street lots, open space lots, golf course lots, and miscellaneous lots within the gated country club project. The main entry will be on Avenue 52, with secondary/emergency access off of Avenida Bermudas and Avenue 52. Residential lots are irregular in shape and range in size from approximately 10,000 square feet to 1 acre. These lots are dispersed around the golf course. The circulation system within the tract consists of private streets with 36 feet and 32 feet widths. Parking on the residential streets will be permitted. Emergency access roads will be 20 feet wide, of 6 inch thick concrete and meander throughout the project where ever there is a 600 foot long, or longer, cul de sac street. The emergency access roads satisfy the Fire Department requirement for emergency access as they connect to nearby streets. Secondary/emergency gates accessing the project will be located near the northeast corner of the project in conjunction with the maintenance yard access road that enters onto 52"d Avenue. Another emergency access gate will also be located at the eastern terminus of Francis Hack Lane, across from the Fire Station. And a third emergency access gate will be located along Avenida Bermudas, across from Calle Nogales where there is an existing stop sign for traffic control. These three secondary/emergency access gates will be controlled electronically and have Knox boxes for emergency vehicle control. These same gates can service the residents of the proposed project when special events might necessitate the closing off of the Avenue 52 entry gate, as well as during times of emergencies. A perimeter wall is proposed along Avenida Bermudas, Avenue 52, and the northern property line. The wall will be kept at a six-foot height on top of a two foot berm. Lot pad heights will be required to be adjusted in order to maintain this wall height. The wall along Avenida Bermudas will have meandering landscaping and wall within a 10 to 32 foot wide parkway beyond the existing concrete sidewalk. The perimeter wall will be constructed along the south side of Avenue 52, southward along the eastern property line until the mountains are reached, and across the northern property line for the Tradition Club property. The northern property line is located north of Avenue 52. The wall along this area will involve the continuation of existing wall designs and the construction of new wall designs. The applicant will be required to continue around the northwest and northeast corners at the southern terminus of Washington Street with the wall that exists along Washington Street for a short distance and then transition to existing wall design, especially along the north side of Avenue 52, east of Washington Street, and with the proposed project wall design along the north property line, west of Washington Street. All wall designs along the northern property line will be the same color (white) on both sides to provide some uniformity, and are to be stuccoed. The applicant will be required to submit a wall plan for the northern property line for review and approval by the City. 5 (1i�t�1 The existing flood control easements will be retained by the Coachella Valley Water District (CVWD) as they are a part of the community wide flood and storm water control system. These facilities were constructed in 1988 by CVWD. The project has been designed around these facilities which include retention basins and channels. A portion of the golf course will utilize the large retention basin located near the northwest corner of the project site. All proposed tentative tract maps that are approved by the City require that particular findings be made as indicated by Section 13.12.120 of the Subdivision Ordinance. The following findings must be made: 1. The proposed map must be consistent with the City General Plan and any applicable specific plan. Staff has determined that the proposed subdivision is consistent with the City's General Plan in that the proposed residential lots exceed the minimum requirements for size, access, and open space requirements. There is no specific plan for this project site. The perimeter wall will be six feet in height and constructed on a two foot berm. All homes constructed within 150 feet of Avenida Bermudas will be restricted to 17 in height in order to comply with the recommendations of the noise study and sound attenuation. Beyond the 150 foot area, the RL Zoning District permits single family homes up to a height of 28 feet. A seventeen -foot height restriction will also be placed on the six lots within the alluvial fan that are subject to approval of Conditional Use Permit 96-031., as the viewshed study and environmental assessment is based upon that height maximum. If the applicant or any future lot owner wants to exceed the 17-foot height restriction, than a revision to the CUP will have to be submitted for approval, with a new viewshed study, and revised environmental assessment conducted. 2. The design of the subdivision or the proposed improvements are not likely to cause substantial environmental damage or substantially and avoidable injure fish or wildlife or their habitat. Staff has determined that the proposed subdivision will have some impacts to the environment, but that with the implementation of certain mitigation measures, as discussed in Environmental Assessment 96-333, the level of impacts will not be significant. Open space easements for portions of lot 27, 28, 29, 30, 233, 234, and 235 will also be required due to the steep slopes that extend onto these proposed lots. Hillside Conservation easements dedicated to the City in perpetuity will be required for those portions of the lots that extend into the 20% or greater slope gradients. The alluvial fan has existing scar damage for which staff has taken into consideration in the determination of the recommendation for approval of the proposed development under Conditional Use Permit 96-031. C 3. The design of the subdivision or type of improvements are not likely to cause serious public health problems. Staff has determined that there are no identifiable significant adverse impacts to the general public's heath, safety, or welfare that would result from the approval of the subdivision, in that the project will have residential and recreational uses that are not typically associated with safety hazards or health problems. In concern for mitigating noise impacts to the residents on the west side of Avenida Bermudas as well as the proposed project, and to mitigate any impacts to the viewshed and aesthetic concerns, staff has determined that the residential lot pad elevations are to be lowered so that there is no need for the perimeter wall to be any higher than six feet on top of a two foot berm along any portion of Avenida Bermudas. 4. The design of the subdivision or type of improvements will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision. Staff has determined that the existing easements for the existing flood and storm water facilities will remain in place, unmodified as these facilities are part of a community -wide system of flood and storm water protection facilities and must not be altered. The proposed project has been designed around these facilities so that the easements and the facilities will not be impacted. Conditional Use Permit The applicant has applied for approval to subdivide and develop six residential lots and golf tee boxes that are located within areas of 20% or greater slopes. Because these areas are within the Hillside Conservation District they will be subject to specific development criteria. Therefore, a special review of these areas has been conducted by staff. There are a total of five specific areas that are subject to the Conditional Use Permit (Attachment 5). The Hillside Conservation Ordinance is an overlay district that applies to all land within the City designated in the General Plan as "Open Space" and shown on the Official Zoning Map as "HC" (Hillside Conservation). More specifically. The HC district and the provisions of Section 9.140.040 of the Zoning Ordinance apply to land meeting the criteria for being above "the toe of the slope," as defined by this Section, within certain sections of land within the City. A portion of the applicant's project site lies within the specified Sections, namely Township 6 South, Range 7 East, Sections 6 and 7, San Bernardino Base & Meridian. In the City General Plan, all hillsides and some alluvial fans are designated Open Space. In general, the dividing line between open space and other land uses is meant to follow and be bounded by "the toe of the slope." The area above the toe of the slope includes not only hillsides, but also alluvial fans which are not protected by flood control structures, and drainage ways and stream courses which have some potential for flooding. 7 11 7 The applicant has submitted a viewshed study for the six lots that indicates that from the vantage point of Calle Colima and the west side of Avenida Bermudas, the highest of the lots with a future 17 foot high house built upon it, the top of the house would only be slightly visible. The house would not visible at all with ten year old landscaping near the perimeter wall along Ave. Bermudas blocking all view of the alluvial fan area. The other vantage point used in the viewshed study is that of Calle Nogales and west side of Ave. Bermudas. Again, this study indicates that with a 17 foot high house built upon the highest lot, the top of the house would only be slightly visible, and with ten year old landscaping, would not be visible at all. Based on this study, staff has determined that the future homes on lots 233, 234, and 235 will be only minimally visible, if at all. The applicant's engineer submitted a slope study to determine land suitability that depicts the existing slope gradients within the area of the proposed six residential lots. This exhibit will be presented for the Planning Commissions consideration at the meeting. The exhibit breaks up the slope gradient into six percentage categories: 0% to 10%, 10.00% to 12.4%, 12.5% to 14.9%, 15.0% to 17.4%, 17.5% to 19.9%, and 20% or more slope. The slope study shows that there is an intermingling of these categories throughout the proposed development area for these six lots. The City Engineering Department has reviewed the slope study and accepts it as accurately depicting the slope gradient for the alluvial fan area and the toe of slope. The exhibit also shows the limits of grading for this area. A condition has been placed on the project to revise the slope study to add a dashed line to indicate the limits of the existing scarred area within the alluvial fan. Those lots with slopes up to 20% that are unscarred and natural will be permitted to be graded for development. Those lots with slopes 20% or greater and unscarred will be required to have conservation easements recorded on them that prohibit any kind of grading or development. In addition, the grading of the six lots will be required to avoid angular flat planes. Contouring shall be smooth, following and/or restoring the natural contours according to the criteria in the Zoning Ordinance. Within the alluvial fan, a road is proposed to access the six lots. The slope study indicates that a portion of the road will be constructed in an area of 20% or greater slope gradient The road, as it is proposed, would result in at least a ten foot scar wall. If the road were realigned, there would be no scar wall. There is an opportunity to realign the road to lower sloped area adjacent to its proposed location that would bring the road in to compliance with the Hillside Conservation District requirements. Staff has included a condition to require the redesign of the road to the lower slopes to ensure compliance with the Hillside Conservation Ordinance. This ordinance requires that maximum retention of vistas, and natural topographic features including mountainsides, ridgelines, hilltops, slopes, rock outcroppings, arroyos, ravines, and canyons. The realignment of the road would allow for the preservation of this ridgeline, which is in keeping with Goal 4-2 of the La Quinta General Plan. This goal states that the City shall maintain alluvial fan and hillside areas as Open Space. All areas with the open space designation shall be subject to all provisions of General Plan Policy 4-1.2.1. regarding development and preservation. 8 009 Site Development Permit The applicant has submitted architectural plans for the proposed clubhouse, cart -barn maintenance building, half -way house, and parking lot (Attachments 6,7 & 8). The proposed clubhouse will be located adjacent to the Hacienda, on the south side. A large entry drive circle will be located in front of the northeast elevation, and will feature decorative pavers. The two story structure will have a total of 16,905 square feet. The architecture of the building is reminiscent of the Mediterranean Period. The design of the building incorporates character defining features found in the architecture of the Hacienda del Gato, such as wood doors and steel framed multi paned windows with wood lintels, recessed windows, whitewashed rock treatments, tile roof, and wooden balcony guardrails. Exterior wall finish will be stucco. The tallest point on the clubhouse (top of chimney) is approximately 33 feet high. Roofline heights vary but do not exceed 28 feet maximum. The floor plan of the clubhouse follows several axial alignments. The exterior colors will consist of white painted stucco finish, black window frame color, natural granitic stone walls, red clay roof tiles, and brick red painted door and trim color. Red brick pavers will be used for exterior walkways. These colors and materials closely match those used at the Hacienda del Gato. A color and materials exhibit has been submitted for review. The proposed cart barn will be connected to the clubhouse by a living arbor structure. The cart barn will feature the same architectural elements found in the clubhouse. The cart barn will provide storage and maintenance for the club's golf carts. Inside the building there will be golf cart storage area for 63 carts, a caddie master office, club repair and cleaning room, golf bag storage room, a restroom, parts room, and golf cart repair area. Outside there will be a wash area and a caddie yard. The proposed cart barn is 4.025 square feet in size. The arbor that connects the cart barn to the clubhouse covers an area of 1,488 square feet. The cart barn features a gabled roof line with the red clay roof tile. The exterior colors and materials will be the same as those proposed for the clubhouse. The floor plan follows one axis line. Staff has required that an additional restroom for employee use be added to the Half -way house. The proposed half -way house will be located near the 9`" green. It will contain a set of restrooms, grill, kitchen, storage room, dining terrace, and cart parking. The same architectural elements found in the clubhouse and cart barn will be used for the half -way house. The proposed maintenance building features the same architecture as the other proposed structures. There will be three sectional overhead roll -up doors on the south elevation. This building will be located near the northeast corner of the project within the proposed maintenance yard accessed from Avenue 52. The maintenance building will contain a chemical storage room, equipment storage room, shop area, restrooms, and offices inside, 9 nOI Outside there will be a fuel island, wash rack, storage areas, soil stockpile bins, and 27 parking spaces. A parking area is proposed with 139 spaces, four of which will be designated for handicapped parking. Twenty-one spaces will be reserved for staff parking. The parking area will be locted across from the Hacienda, on the east side of the driveway road. At the northwest corner of the parking lot will be a tennis court screened with a perimeter hedge. The perimeter of the parking area will be screened by large trees and berms with grass cover. The interior parking lot planters will have shade trees, evergreen shrubs and ground cover. Annuals will be planted at the northwest and northeast corners of the parking area for color. At the southwestern corner of the parking lot is an existing water well that the applicant proposes to lower the concrete casing into the ground and screen with planting I order to make it less visible. The parking area landscaping will soften the paved area. A proposed realignment of the original driveway is proposed to access the proposed clubhouse and cart barn. This includes the new entry circle in front of the proposed clubhouse. Exhibits show that the south part of the Hacienda driveway center median will be removed and widened in order to accommodate existing water well. The parking area will be located directly east of the Hacienda, and across from the driveway. The plan as proposed would also require partial, if not complete, removal of an existing planter adjacent to the Hacienda. The plan also shows that the existing rock curb lining the original driveway will be removed, and the entry gate and pilasters will be removed to another location near the Hacienda. The majority of the eucalyptus trees lining the driveway will be preserved in a center median planter, the existing trees will be relocated elsewhere on the project site. Landscape plans are included as attachments 9, 10, & 11. The proposed landscaping includes the golf course, landscape lots within the project, the main entry landscaping, and perimeter landscaping outside of the project. The plans have been reviewed by the Coachella Valley Water District for appropriateness of plant species for the desert environment and for efficient irrigation concerns. Certificate of Appropriateness On January 16, 1997, the Historic Preservation Commission reviewed and recommended to the Planning Commission and City Council approval for several modifications to the historic Hacienda del Gato and the immediate grounds as they relate to the Site Development Permit for the Tradition Club project. The Draft Minutes of this meeting are attached (Attachment 12). The historicity of the Hacienda del Gato was documented in the "Marshall Ranch/Hacienda del Gato Historic Resources Evaluation," a report prepared by Mellon & Associates, in accordance with the requirements of the California Environmental Quality Act. The report described the Hacienda as nestled below the Santa Rosa Mountains with 10 1 ` 1 D the main entrance off of Avenue 52, near Washington Street. The estate consists of a gated entry and long driveway lined with mature plantings. The driveway leads to the Hacienda and auxiliary buildings on the grounds. Mature eucalyptus trees and palms frame the rough hewn rock wall which holds the iron entry gates. Past the gate, a driveway with stone curb walls meanders to the entry circle of the Hacienda. The driveway is lined with mature trees. The driveway functions as an access road for the estate and continues past the hacienda, south to other structures on the estate. While the exact dates of the various components of the estate (entry gates/walls, curbed roads, gardens and walkways) is not known, it is reasonable to assume that these features were established between the late 1920's and 40's. The Mellon report states that "the Hacienda del Gato Main House and garage, the sunken courtyard, and entry drive gardens are over fifty years old and are significant elements characterizing a desert ranch/estate. These elements possess a high level of architectural integrity in terms of location, design, setting, materials, workmanship, and feeling." The report concludes that the Hacienda, garage and entry circle, sunken courtyard, gardens, and entry gate appear to be eligible for listing on the National Register of Historic Places under two criteria of local significance. These components of the estate appear to also be eligible for designation as a City of La Quinta Landmark. Staff has reviewed the proposed modifications and requests for their compatibility with the Secretary of the Interior's Standards for the Treatment of Historic Properties. The fundamental goal of the rehabilitation of the Hacienda and grounds is to protect the historical significance by making a visual distinction between old and new, and to protect those elements that are character -defining features of the historic estate. This goal applies not only to structures but to the grounds surrounding the structures. The grounds, including the planter, rock curb, and landscaping, are key components of the historical setting or context, as identified in the Mellon report. The Secretary of the Interior's Standards states that new work to a historic property be "compatible with the size, scale, color, material, and character of the property, neighborhood, or environment. New additions, exterior alterations, or related new construction shall not destroy historic materials that characterize the property." And that "new additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the yIture, the essential form and integrity of the historic property and its environment would be unimpaired." There are recommendations contained in the Secretary of the Interior's Standards that address several of the applicant's specific requests. The specific requests and staff comments are as follows: 1. The original driveway into the estate is lined with a rock curb -like wall. The proposed project would realign the driveway in certain places to accommodate the applicant's grading needs, and to create another drive aisle to facilitate two-way traffic around a center median planter. The rock curb would be entirely removed and is proposed to be replaced with a new rock wall. The request to remove the rock curb lining is not recommended as masonry features such as this are important in defining the overall historic character of the property. If the rock curb is removed, the character is diminished. An effort should always be made to repair and stabilize the historic wall rather than replace with a new one. Staff consulted with the Fire Department to ensure adequate access for emergency vehicles so that portions of the rock curb can remain in place for the proposed realignment of the driveway. Staff recognizes that portions of the wall are deteriorates and should be removed and that these wall portions will no longer accommodate the current proposal. However, staff has identified portions of the driveway nearest the Hacienda entry circle, the largest planter median with the mature eucalyptus trees, and the planters adjacent to the garage as significant character defining features. These planters with rock curbs are recommended to be in to the proposed driveway plans. 2. The applicant proposes to relocate the original entry gate and pilasters at the Old Avenue 52 to the immediate entrance of the Hacienda. Although the relocation of historic features is not recommended in the Standards for Rehabilitation, it is necessary to move the gate due to it's narrow width and the need for adequate access for emergency vehicles, and due to the proposed alignments of the driveway. The gate and pilasters are to relocated just before the existing entry circle in front of the Hacienda. The gate will be relocated within the historic landscape of the estate, thus preserving this character defining feature and maintaining the historic context. The original planters outside the gate will be removed. Staff supports the relocation of the gate and pilasters to the proposed new site as relocation is a good alternative to removal as the gate will still be in general historic context with the Hacienda. Staff recommends that the gate and pilasters be sensitively moved, and that they be installed to their original width, height, and finish. 3. The retention of the existing trees along the driveway is in keeping with the Secretary of the Interior's Standards for Rehabilitation, in that retaining the historic relationship between buildings, landscape features, and open space is recommended. Staff supports the applicant's proposal to retain the eucalyptus trees along the driveway in a median - style planter. The retention of these trees will help maintain the character defining feel of the long, tree -lined original driveway. 4. The applicant proposes to remove and relocate the existing palm trees within the proposed realignment of the driveway. The removal and relocation of these palm trees is supported by staff in that the palms will be relocated to other areas of the project site. The removal of these trees allows for the realignment of the driveway to accommodate the applicant's grading design and access for emergency and other vehicles to the proposed clubhouse and cart barn. 12 i ) 1 `' 5. The applicant proposes to construct a clubhouse and cart barn in close vicinity to the Hacienda. This involves the consideration of the compatibility between new construction and the existing historic structure and grounds. The Secretary of the Interior's Standards for Rehabilitation and Guidelines for Rehabilitating Historic Buildings states that new additions, exterior alterations, or related new construction is not to destroy historic materials, features, and spatial relationships that characterize the property. The standards also state that new work shall be differentiated from the old and will be compatible with the historic materials, features, size, scale, and proportion, and massing to protect the integrity of the property and its environment. The architectural plans and exhibits have been reviewed by staff and the Historic Preservation Commission for compatibility with the Hacienda. The architectural details of the clubhouse and cart barn proposes wood lintels over windows and some doors, arched entries, gabled roof lines with mud set red clay tile roofing, wood balcony guardrails, and other features are in keeping with the materials and design of the Hacienda. Architectural forms found in the Hacienda are repeated in the design of the clubhouse and cart barn. The proposed exterior colors and materials for the clubhouse and cart barn include granitic stone wall treatments painted white, red clay brick pavers, red clay roof tile, steel window frames painted black white stucco walls, and door and trim color to be a brick red. Staff and the Historic Preservation Commission found that the proposed clubhouse and cart barn architectural design is compatible with that of the Hacienda. The incorporation of particular features found at the Hacienda into the architecture of the clubhouse and cart barn provide for a continuation of the historic design, while also providing enough differences to meet the recommended distinction between "old" and "new". The proposed heights of the new buildings, their size and massing, and exterior colors and materials are also compatible with the Hacienda. 6. The applicant proposed to remove the planter adjacent to the Hacienda's garage, however, the Historic Preservation Commission did not recommend approval of this removal, but rather that the proposed driveway and entry circle in front of the clubhouse be redesigned so that the elevation is lower in order to prevent potential drainage damage to the planter or any modification to the planter, and designed to be smaller so that there is a physical separation between the proposed new construction and the historic planter in order to protect the historic character of the original grounds 7. The Historic Preservation Commission recommended that the proposed location , design, and screening of the parking lot was acceptable with regard for the Hacienda del Gato. It was understood that the proposed parking lot is necessary to service the proposed clubhouse, cart barn, and Hacienda. The proposed location is physically separated from the Hacienda and its grounds by the proposed realigned driveway. It will be screened and softened by the proposed landscaping. 13 '7 Environmental Issues Environmental Assessment 96-333 was prepared by staff for the proposed project, including the tentative tract map, change of zone, conditional use permit, site development permit, and certificate of appropriateness. An Initial Study Checklist was prepared in which 15 environmental issue areas were examined for possible significant adverse impacts resulting from the proposed project. Of the 15 issue areas, 12 of the areas had answers to questions for which the responses were "Potentially Significant Unless Mitigated." Each question on the checklist is discussed in the Addendum accompanying the checklist. Mitigation measures were identified for each of the 12 issue areas identified with potential significant impacts. In order to assess the environmental impacts for the project, staff reviewed soils reports, grading plan reports, a hydrology study, geotechnical reports, archaeological reports, an acoustical study, historic resource studies, and environmentally assessments prepared for previously proposed projects on this project site. These reports, together with the previous environmental assessments, staff was able to make the determination that with appropriate and feasible mitigtion measures, this project would qualify for a Mitigated Negative Declaration of Environmental Impact. The Checklist and Addendum are attached to this report (Attachment 13). Public Notice The Community Development Department advertised the project in the Desert Sun newspaper on February 5, 1997. All property owners within 500-feet of the affected area were mailed a copy of the public hearing notice as required. Public Agency Review Staff mailed a copy of the applicant's requests to all public agencies on October 17, 1996, and subsequent dates as revised materials and information were submitted. Public Comments Attached are the letters from the public regarding this project (Attachment 14). Concerns are with potential traffic along Ave. Bermudas, the proposed perimeter wall, and residential development in the alluvial fans and hillsides. RECOMMENDATIONS: 1. Adopt Planning Commission. Resolution 97-1 recommending to the City Council that Environmental Assessment 96-333 be certified with a Mitigated Negative Declaration of Environmental Assessment according to the findings set forth in the attached resolution. 14 r 1 rT 2.

WHEREAS. said Environmental Assessment has complied with the requirements of "The Rules to Implement the California Environmental Quality Act of 1970" as amended, Resolution No. 83-63, in that the Community Development Director has conducted an initial study (Environmental Assessment 96-333) and has determined that although the proposed project could have a significant adverse impact on the environment, there would not be a significant effect in this case because appropriate mitigation measures were made conditions of approval, and a Mitigated Negative Declaration of Environmental Impact should be filed; and, WHEREAS, at the Public Hearing held on February 25, 1997, upon hearing and considering all testimony and arguments of all interested persons desiring to be heard, said Planning Commission did make findings to justify the recommendation for certification of said Environmental Assessment, and, WHEREAS, at said Public Hearing, said Environmental Assessment was recommended for certification based on said findings and subject to certain mitigation measures; and, i-i 1 r; WHEREAS, the La Quinta Planning Commission on February 25, 1997, did find the following facts to justify recommending certification of said environmental assessment: l . The design and improvement of proposed Tentative Tract 28470, Change of Zone 96-081, Conditional Use Permit 96-031, Site Development Permit 96-599, and Certificate of Appropriateness 96-001 are consistent with the Low Density Residential land use goals and objectives of the La Quinta General Plan, in that the proposed project is in keeping with Goal 2-1 to develop low density residential areas with generous areas of open space. 2. The subject site is physically suitable for a 241 lot subdivision, 18-hole golf course, clubhouse, maintenance building, cart barn, and half -way house for the golf course, as development is only proposed for the residentially -zoned, and proposed golf course zoned areas, except for those areas included in Conditional Use Permit 96- 031 which are above the toe of the slope. 3. Tentative Tract 28470 is consistent with the development standards of the Municipal Zoning and Land Division Ordinance, as the project site is zoned R-L (Low Density Residential), FP (Flood Plain), and OS (Open Space). The proposed Change of Zone from R-L to GC (Golf Course) for a portion of the proposed golf course is consistent with the requirements of the Zoning Ordinance, in that the proposed project exceeds requirements for usable open space for a low density planned residential developments. 4. The design of Tentative Tract 28470, Change of Zone 96-081, Conditional Use Permit 96-031, Site Development Permit 96-599, and Certificate of Appropriateness 96-001 are not likely to cause adverse environmental impacts to cultural resources provided that conditions of approval related to mitigation measures for the archaeological and historical resources are complied with prior to and during project development. The Coral Reef Mountains will remain natural open space. 5. Proposed Tentative Tract 28470, Change of Zone 96-081, Conditional Use Permit 96-031, Site Development Permit 96-599, Certificate of Appropriateness 96-001 is not likely to cause public health problems as the project has been reviewed by the Fire Department and the Building & Safety Department for those specific issues. 6. The design of Tentative Tract 28470 will not conflict with existing public easements, as the project has been designed around, and with consideration for, these easements. r NOW, THEREFORE, BE IT RESOLVED by the Planning Commission of the City of La Quinta, California, as follows: That the above recitations are true and correct and constitute the findings of the Planning Commission in this case; 2. That it does hereby concur with the environmental determination and recommend certification of Environmental Assessment 96-333 for the proposed Tentative Tract 28470, Change of Zone 96-081, Conditional Use Permit 96-031, Site Development Permit 96-599, and Certificate of Appropriateness 96-001. PASSED, APPROVED and ADOPTED at a regular meeting of the La Quinta Planning Commission, held on this 25th day of February, 1997, by the following vote, to wit: AYES: NOES: ABSENT: ABSTAIN: JACQUES ABELS, Chairman City of La Quinta, California ATTEST: JERRY I ERMAN, Community Development Director City of La Quinta, California PLANNING COMMSSSION RESOLUTION 97- A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF LA QUINTA, CALIFORNIA. RECOMMENDING APPROVAL OF A CHANGE OF ZONE FROM RL (LOW DENSITY RESIDENTIAL) TO GC (GOLF COURSE) ON A PORTION OF TENTATIVE TRACT 28470 GENERALLY LOCATED SOUTH OF 52ND AVENUE AND EAST OF AVENIDA BERMUDAS CASE NO. CHANGE OF ZONE 96-081 - TRADITION CLUB ASSOCIATES, LLC WHEREAS. the Planning Commission of the City of La Quinta, California, did on the 25 h day of February, 1997, hold a duly -noticed Public Hearing as requested by Tradition Club Associates, LLC, on the request to rezone a portion of the proposed golf course contained within Tentative Tract 28470, generally located southeast of the corner of 52"d Avenue and Avenida Bermudas, more particularly described as follows: A PORTION OF SECTIONS 6 AND 7, T6S, R7E, SBB&M WHEREAS, at said Public Hearing held on February 25, 1997, upon hearing and considering all testimony and arguments of all interested persons desiring to be heard, said Planning Commission did make the following findings to justify the recommendation for approval of said Change of Zone: 1. The proposed change of zone will result in consistency with the goals, objectives, and policies of the La Quinta General Plan for portions of the proposed golf course. 2. Approval of the change of zone will not create conditions materially detrimental to the public health, safety and general welfare. 3. The proposed zone change is compatible with the zoning on adjacent properties in that golf course land uses are generally found within residential developments, both private and public. 4. The proposed zone change is suitable and appropriate for the subject property in that the area of the proposed golf course follows an existing design created by the construction of flood control facilities in 1988 by the Coachella valley Water District. 5. Approval of the zone change is warranted because the situation and the general conditions of the property have substantially changed since the existing zoning was imposed by way of an amendment to the Zoning Ordinance effective September 1996 in which golf courses were no longer a permitted use in residential zoning districts, and that they are now required to be within the GC (Golf Course) Zoning District. 0I II Now, therefore, be it resolved BY THE Planning Commission of the city of La Quinta, California, as follows: 1. That the above recitations are true and correct and constitute the findings of the Planning Commission in this case. 2.

The proposed Conditional Use Permit has been included in the environmental assessment as required by the California Environmental Quality Act, performed under Environmental Assessment 96-333, and has been determined not to result. in substantial environmental damage or substantially and avoidable injure fish or wildlife or their habitat. 5. The proposed Conditional Use Permit is not likely to cause serious public health problems or adversely impact the general public welfare or safety in that geotechnical studies of the subject areas and conditions of approval will reduce the hazards from slope failure, rockfall hazard, and erosion from drainage.

Chairman Millis asked if there were any plans showing the entry gate. Mr. Eric Carlson, AIA, architect for the project, presented and explained the drawings. Discussion followed regarding the architecture detailing to be used. 3. Mr. Carlson, AIA Architects, addressed the issues that were raised in the staff report and showed photographs of the existing wall. As a solution to the auto -court impacting the existing low rock wall. They decided to drop the elevation of building(s) and auto -court to allow a grade change that would retain the existing wall. The existing wall would have the last two feet removed to allow a natural tie in with the new auto -court. 4. Chairman Millis asked what the perimeter wall material treatment would consist of. Mr. Carlson stated it was to be stone similar to the existing to carry the same theme throughout the auto -court. Chairman Millis asked if they would be able to locate the same stone. Mr. Carlson stated they intended to use what was not going to be used f_-rom other areas on the property. Staff stated they would require that the applicant make a definite distinction between the old and new sections. Mr. Mike Rowe, Winchester Development stated it was the applicants desire to retain the theme and look of an old hacienda. He went on to explain that the existing walls were two feet high and they intended to construct the wall on the east side 6-inches high and detail/color it to denote the difference between the two walls. Staff explained that they were concerned about the transition between the two elements and the proposed changes would satisfy staffs concerns. 6. Chairman Millis asked if there was to be any difference in the materials to be used for the driveway. Mr. Rowe stated there would be none, it was to be asphalt and dirt. 7. Planning Manager Christine di Iorio stated staff had spoken with the Fire Department and they were comfortable with the designation of the east entry lane for Fire Department emergency use. Discussions followed regarding the driveway dimensions and signs to notify vehicular traffic of the Fire Department access. HPC1-16 2 Historical Preservation Commission January 16, 1997 8. Mr. Mike Rowe asked about the planters in front of the entry gate being moved. Planning Manager Christine di Iorio explained that staff originally wanted to retain the planter and not compromise the existing structure. As a result of discussions with the applicant, they had no objections to their recommendation. Staff will document the planters with photographs before they are removed. Chairman Millis asked if staff was comfortable with the changes as submitted by the applicant. Staff stated they were in agreement. 7.

Chairman asked what the differences were between what our Historic Survey consultants had found and this list. Staff stated the consultants had not done any field work to date. 2. Commissioner DeMersman asked why The Keith Companies would take the time to do this. Chairman Millis stated it was probable because they obtained the software that allowed them to do this. Chairman Millis suggested the Commission wait to see what the Survey produced and see if the difference warranted looking into the offer. As most computer programs will rank the historic buildings, the only ones that may be missing from the Survey results, may not be of any significance. 3. The Commission determined to take no action at this time, but wait to see what the Survey produces. B. Certified Local Government (CLG) Professional Qualifications update. 1. Associate Planner ]Leslie Mouriquand explained that the CLG report was due and each Commissioner needed to update their resume for preparation to SHPO. 2.

In addition, there is a request for a change of zone from the existing RL (Low Density Residential) to GC (Golf Course) for a portion of the proposed golf course, and a request for approval of a Conditional Use Permit to allow the creation of six residential lots and golf tee boxes in the Hillside Conservation Zoning District. Finally, there is a request for approval of the architectural designs for a clubhouse, maintenance building, cart barn, and half -way house to service the golf course. The existing historic hacienda will be rehabilitated for use as administrative and sales offices for the project. The project site is located on Avenue 52, at the southern terminus of Washington Street, in La Quinta, California. The property is the historic estate known as the Marshall Ranch. The historic property is known as the Hacienda del Gato, which is listed on the State Historic Resources Inventory. Formerly the property had been ranched with dates and citrus. Several out -buildings and a workers house are also located on the property The Applicant proposes to -develop the estate into a private country club with golf course and custom home sites, and an administrative/sales center. The City of La Quinta is the Lead Agency for the project review, as defined by Section 21067 of the California Environmental Quality Act (CEQA). The Lead Agency is the public agency which has the principal responsibility for carrying out or approving a project which may have a significant effect upon the environment. The City of La Quinta, as the Lead Agency, has the authority to oversee the environmental review and to approve the land use designations. 1.2 PURPOSE OF INITIAL STUDY As part of the environmental review for the proposed Tentative Tract Map, Change of Zone, Conditional Use Permit and Site Development Permit, the City of La Quinta Community Development Department staff has prepared this Initial Study. This document provides a basis for determining the nature and scope of the subsequent environmental review for the proposed subdivision and future development of the land. The purposes of the Initial Study, as stated in Section 15063 of the State CEQA Guidelines, include the following: To provide the Agency with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR) or a Negative Declaration of Environmental Impact for the tentative tract map, zone change, and development applications; 059 3 To enable the applicant, or the City of La Quinta, to modify the project, mitigating adverse acts before an EIR is prepared, thereby enabling the project to qualify for a :Mitigated Negative Declaration of Environmental Impact; To assist the preparation of an EIR, should one be required, by focusing the analysis on those issues that will be adversely impacted by the proposed project; To facilitate environmental review early in the design of the project, To provide documentation for the findings in a Negative Declaration that the project will not have a significant effect on the environment; To eliminate unnecessary EIR's; and, To determine whether a previously prepared EIR could be used with the project. 1.3 BACKGROUND OF ENVIRONMENTAL REVIEW The proposed project applications were deemed subject to the environmental review requirements of CEQA in light of the intended development and potential impacts upon the property and surrounding area. This Initial Study Checklist and Addendum was prepared for review by the City of La Quinta Historic Preservation Commission, Planning Commission and certification by the City Council. 1.4 SUMMARY OF PRELIMINARY ENVIRONMENTAL ASSESSMENT This Initial Study indicates that there is a potential for adverse environmental impacts for some of the issue areas contained in the Environmental Checklist (Earth Resources, Water, Noise, Public Services, Utilities, Aesthetics, Cultural Resources). Mitigation measures have been recommended for the proposed subdivision and related development applications which will reduce potential impacts to insignificant levels. As a result, A Mitigated Negative Declaration of Environmental Impact will be recommended for this project. An EIR will not be necessary. SECTION 2: PROJECT DESCRIPTION 2.1 PROJECT LOCATION AND ENVIRONMENTAL SETTING The City of La Quinta is a 31.18 square mile municipality located in the southwestern portion of the Coachella Valley, in Riverside County, California. The City is bounded on the west by the City of Indian Wells, on the east by the City of Indio and Riverside County, on the north by Riverside County, and federal lands to the south. The City of La Quinta was incorporated in 1982. n66 4 2,2 PHYSICAL CHARACTERISTICS The proposed project site is a portion of a 746.6 acre parcel of land. The land involved in this project has been farmed in the historic and recent past, and developed in the 1930's with a large home, workers house, and several out -buildings to service the former ranch operation. The property is located adjacent to and within the Coral Reef Mountains, located at the mouth of the La Quinta Cove area. The proposed development will be largely contained on the flatter alluvial fan area. Six residential lots are proposed at the mouth of an alluvial fan that will require approval of a Conditional Use Permit due to the slope considerations and development restrictions contained in the City's Hillside Development Ordinance. A large area of the property was subjected to mass grading in 1988, by the Coachella Valley Water District, in conjunction with the East La Quinta Flood Control Master Planned facilities and a previous development project that was not constructed. Thus, a large portion of the project area has been highly disturbed. The agricultural activities on the ranch ceased several years ago in anticipation of proposed development. There are only a few date and citrus trees left, except for those around the cluster of houses and out- buildings. Several eucalyptus trees line the south side of Old Avenue 52 which is located within the project site, and the original driveway leading into the hacienda. 2.3 OPERATIONAL CHARACTERISTICS The proposed tract will create 241 single family custom residential lots for house construction, and for an 18-hole golf course, clubhouse, maintenance building, and cart barn. A circulation system of private streets is proposed to provide access throughout the tract. The development will be a private gated community. Five retention basin are proposed for the project, which will supplement the existing stormwater retention system. The historic mansion will be rehabilitated and used as an administrative/sales center for the country club. 2.4 OBJECTIVES The objective of the proposed subdivision is to create 241 new single family custom residential lots within a planned private development for profit. These lots will be offered for sale by the applicant. The Applicant proposes to develop an upscale private country club development with an 18-hole golf course. 2.5 DISCRETIONARY ACTIONS A discretionary action is an action taken by a government agency that calls for the exercise of judgment in deciding whether to approve a project. For this project, the government agency is the City of La Quinta. The proposed tentative tract map and future development will require discretionary approval by the Historic Preservation Commission and Planning 5061 Commission, and approval by the City Council. The following discretionary approvals will be required for this project: Certification of the Environmental Assessment 96-333, Certificate of Appropriateness 96-001, Approval of Tentative Tract Map 28470; Approval of the Final Tract Map 28470; Approval of Conditional Use Permit 96-031; Approval of Change of Zone 96-081, Approval of Site Development Permit 96-599 2.6 RELATED PROJECTS The project consists of a proposed tentative tract map, grading plan, various approvals under a Certificate of Appropriateness for the historic structures, a proposed Change of Zone, Conditional Use Permit, and a Site Development Permit. Four previous projects (San Pebbles Country Club, Heritage Club, Crystal Canyon Country Club, and The Tradition at La Quinta) proposed for the project site have been reviewed by the City in the past dozen years. All of the previous proposed projects were resort oriented developments which included a range of 330 to 890 homesites and a golf course. Most of these prior approvals and plans have expired. Environmental studies were prepared for these previous projects. The Coachella Valley Water District graded the project site for construction of retention basin facilities in 1988. In 1985 and 1987, the City approved the vacation of portions of Avenue 52 (now referred to as Old Avenue 52) in order to facilitate future development of the immediate area. A new alignment for Avenue 52 was designed, approved, and constructed by the City that is located adjacent to the northern property line of the project site. SECTION 3: ENVIRONMENTAL ASSESSMENT This section analyzes the potential environmental impacts associated with the land use, subdivision design, architectural design, and historic architectural approval of the proposed development. The CEQA Checklist issue areas are evaluated in this addendum. For each checklist item, the environmental setting is discussed, including a description of the existing conditions within the City and the areas affected by the proposed project. Thresholds of significance are defined either by standards adopted by responsible or trustee agencies, or by referring to criteria in CEQA (Appendix G). 3.1 LAND USE AND PLANNING Regional Environmental .Setting The City of La Quinta is located in the Coachella Valley, in the eastern portion of Riverside County. The valley is abundant with both desert plant and animal life. The 6 062 topographical relief ranges from -237 feet below mean sea level (msl) to about 2,000 feet above msl. The valley is a part of the Colorado Desert region. Surrounding the valley are the San Jacinto Mountains, the Santa Rosa Mountains, the Orocopia Mountains, and the San Bernardino Mountains. The San Andreas fault transects the northeastern edge of the valley. Local Environmental Setting The proposed project is located at the southern terminus of Washington Street, at Avenue 52, east of Avenida Bermudas. The land is partially vacant cove property that has been farmed in the past, and partially developed with a clustering of two houses and two out- buildings. The southern end of the property is dry and sparsely vegetated with some natural desert vegetation. Relic trees from the past agricultural use are located near the existing structures at the north -central portion of the property. Previous grading activity has disturbed a large portion of the property. A. Would the project conflict with the general plan designation or zoning? Potential Impact Unless Mitigated. In 1992, a portion of the property was rezoned from R-1-10,000 and R-2-20,000 to R-2, and from Hillside Conservation (HQ to R-2 through realignment of the R-2 to the toe of the slope. Those areas above the toe of the slope remain HC zone. The toe of slope is determined according to the criteria in the Zoning Ordinance. In 1996, through a city-wide Zoning Ordinance Update, the R-2 designation was reclassified as RL (Low Density Residential District), and the HC to Open Space (OS). That area included in the flood and drainage facilities on -site is designated as FP (Flood Plain District) on the City's Zoning Map, and W (Watercourse) on the General Plan. The La Quinta General Plan requires that golf courses be designated with the special golf course (GC) zoning district. The applicant has submitted a request for a Change of Zone from RL to GC Golf Course District for that portion of the proposed golf course not in the FP designated area. This application will be processed concurrently with the tentative map application. The change of zone will serve as mitigation for land use designation compliance. Adjacent land uses and their designations consist of new Avenue 52 along the northern boundary, with scattered residential north of that, cove residential to the west, vacant natural areas and flood control facilities to the south, and ranch properties and steep hillsides to the east. At the northwest corner is a City park and a fire station. The adjacent land use designations and zoning districts consist of RC (Cove Residential) to the west, OS (Open Space) to the south and southeast, RL (Low Density Residential) to the east and north, MC (Major Community Facilities) and PR (Parks and Recreation) to the northwest. These adjacent land uses and designations are compatible with the proposed land use of this project. The proposed development in the hillside alluvial fan areas is demonstrated that those areas meet certain criteria contained in the Zoning Ordinance 063 7 pertaining to development on slopes. Those residential lots that encroach into slopes .20& or greater will be required to have conservation easements dedicated to the City in )erpetuity to ensure that those areas remain in open space. 3. Would the project conflict with applicable environmental plans or policies adopted by agencies with jurisdiction over the project? 'otentially Significant Unless Mitigated. The City of La Quinta has jurisdiction over his project. The primary environmental plans and policies pertinent to this project are dentified in La Quinta's General Plan, the General Plan E1R, the La Quinta Master Environmental Assessment, and the City's CEQA Guidelines. The proposed project includes development of a golf course tee box (#17), holes #2 and 18, and six residential lot sites (Lots 230 through 236) located apparently above the toe of slope. These areas are within the Hillside Conservation Zoning District. The exact line of demarcation between the RL and H-C Zoning Districts according to the criteria in the Zoning Ordinance through the preparation of a detailed slope analysis. A slope analysis for the six residential lot area that depicts the toe of the slope, and the various slope gradients within the limits of proposed grading. The slope gradient was differentiated into 0% - 10% slope, 10.0% - 12.4% slope, 12.5% - 14.9% slope, 15.0% - 17.4% slope, 17.5% - 19.9% slope, and 20% or more slope (Source: Keith International Inc.). Those areas within the 20% or greater slopes will not be permitted to be developed and will require conservation easements dedicated to the City in order to preserve open space. C. Would the project affect agricultural resources or operations (e.g. impact to soils or farmlands, or impacts from incompatible land uses)? No Impact. The La Quinta General Plan does not contain an agricultural land use designation although there are agricultural land uses extant in the south and southeastern portions of the City. Historically, there has been farming activity in several sections of the City, however, that has largely been replaced by resort and residential development over the past 15 years. The property involved in this project has been disturbed by farming activities since 1902, and periodic flood events. Active farming of the property ceased several years ago in anticipation of development. There are only relic farming activities adjacent to the east of the project site. The historic ranch located adjacent to the east is not currently under cultivation. Thus, no impact on any agricultural resources or operations in the immediate area is likely to result from the proposed subdivision (La Quinta General Plan, Site Survey). 8064 D. Would the project disrupt or divide the physical arrangement of an established community (including a low-income minority community)? No Impact. The project site will be developed with single family lots for general market sale. A private clubhouse and 271 acre l8-hole golf course will be developed, along with a clubhouse, maintenance building, cart barn, and a half -way house. The half -way house is a structure mid -way in the golf course that will have a snack bar and restrooms. Residential land uses are located in all directions of the project site, except for the mountains adjacent to the east and southeast, and the south where there are flood control dams, retention basins, etc.. The future development of these lots will not disrupt or divide the community. The proposed development will not affect the physical arrangement of the existing neighborhoods (Sources: Site Survey; Proposed Site Plan). The project is proposed to be developed in four phases, with Phase I consisting of the golf course. 3.2 POPULATION AND HOUSING Regional Environmental Vetting Between 1980 and 1990, the population of La Quinta expanded 125%, as reported by the U.S. Census, making the City the second fastest growing city in the Coachella Valley. During that time period, the number of residents in La Quinta blossomed from 4,992 to 11,215. From 1990 to January of 1996, the population grew from 13,070 to 18,050. These figures are based upon information provided by the U.S. Census Bureau, the State Department of Finance, and the Coachella Valley Association of Governments (CVAG). La Quinta's population ranks sixth largest of the nine cities in the Coachella Valley. Annual average growth rate has been approximately 10% in recent years. The projected population of La Quinta by the year 2000 is anticipated to be 23,000 (Source: Community Development Department). The average age of a City resident is 32 years. Persons over the age of 45 make up 27% of the City's population (Source: 1990 Census). In addition to permanent residents, La Quinta has approximately 9,300 seasonal residents who spend three to six months in the City. It is estimated that 30% of all housing units in the City are used by seasonal residents (Source: Community Development Department). The total housing stock as of 1996, is listed at 9,352 units. Single family units make up 68 percent of the available .housing stock. The housing unit breakdown is as follows: 8,624 detached single family, 481 multi -family units, and 247 mobile homes. The average number of persons per household is 3.15 (Source: Department of Finance 1996). Median home prices in La Quinta are approximately $112,000 which is lower than the average for Riverside County ($120,950), but less than other Southern California counties (Source: La Quinta Economic Overview 1996 Edition). 065 9 Ethnicity information from the 1990 Census revealed that the composition of La Quanta's population is 70% Caucasian, 26% Hispanic, 2% Afro-American, 1.5% Asian, and 1.0% Native American. The 1990 Census indicates that 8 1 % of the La Quinta residents are high school graduates and 2 1 % are college graduates (Source: Census/Estimates). Local Environmental.Setting The project site consists of a 746.6 acre parcel of largely vacant cove and hillside land. There are two existing housing units on the property. One unit is a caretakers unit scheduled for demolition, and the other is a large hacienda that will be incorporated into the project as a sales and administrative office. A. Would the project cumulatively exceed official regional or local population projections? Less Than Significant Impact. The development planned for this project will ultimately result in the construction of 241 new custom built detached single family units. While the City's average population is 2.85 per dwelling unit, the proposed project is projected to have a lower per unit population given the fact that it will be a private country club with high -end custom home lots. Typically, people buying into this type of project are among the high income individuals, usually older, with grown children no longer living with them. Often they will be seasonal residents, as opposed to permanent residents. Using the factor of 1.94 people per unit, the potential build -out population for the project could be 467.54 new residents in the City. Temporary construction -related jobs will be created as the new units, clubhouse and other buildings are built. New permanent or temporary jobs will be created as a result of the project. There may be new jobs created for administration and maintenance of the country club and golf course, managers and servers for the half -way house and clubhouse, and security personnel for the country club. The number of new jobs generated by the project is estimated by the applicant to be 80 to 90. No jobs will be lost as a result of the project as no one is currently living on the property. New jobs will benefit the community, and result in a positive impact. B. Would the project induce substantial growth in an area either directly or indirectly (e.g. through projects in an undeveloped area or extension of major infrastructure)? Less Than Significant Impact. The proposed subdivision and related development will make an impact in the surrounding area as major infrastructure could be altered or required to be extended to the project site (Source: Site Survey). This impact is not anticipated to be significant, as there is existing development to the west, north, and east of the project site with infrastructure already in place. Some of this development first appeared in the mid-1930's (Source: Draft Historic Context Statement for City of La Quinta). The immediate area around the project site has been developed to the point that 10 o6fn there are few vacant parcels remaining. An existing telephone company fiber optic cable line will need to be relocated from its present location along Old Ave. 52 to a location approved by the telephone company. The applicant is responsible for coordinating and paying for the relocation. C. Would the project displace existing housing, especially affordable housing? Less Than Significant Impact. Two existing residential units are located on the project site the hacienda and a caretakers house. The future development plan is to create 241 custom single family homesites utilizing private funds. The proposed project will result in the removal of one existing housing unit that has been used historically as housing for the ranch caretaker. The house is not currently occupied. The applicant has requested permission to demolish the structure. Demolition will be subject to approval by the City Council (Source: Site Survey; Application Materials, Historic Preservation Ordinance). 3.3 EARTH RESOURCES Regional Environmental Setting The City of La Quinta has a relatively flat, but gently sloping topography, except for the hillside area on the southern and western portions of the City. Elevations in the southeastern portion of the City reach 1,400 feet above msl. Slopes on the valley floor area of the City are gentle, except in the rolling sand dune areas. The alluvial soils that make up most of the City are underlain by igneous -metamorphic rock, as seen in outcrops in the Santa Rosa Mountains and the Coral Reef Mountains. Soils on the valley floor are made up of very fine grain unconsolidated silty sands. The Coachella Valley is underlain by hundreds of feet to several thousand feet of Quaternary fluvial, lacustrine, and aeolian soil deposits (Southland Geotechnical 1996:6). Local Environmental .Setting The area where the parcel is located is in a historical part of the City. A review of historical aerial photographs indicates that the site has been farmed. The elevation of the property ranges from approximately 42 to 1,482 feet above mean sea level (Source: VTTM 28470, USGS La Quinta Quad Map). A large portion of the project site will not be developed, as it is located in the steep, rocky Coral Reef Mountains. There is an inferred earthquake fault line located approximately 1/2 mile to the south of the southern boundary of the parcel, and one 3/4 mile to the east. There has been no recorded activity along these fault lines, thus there is a low probability for such activity to occur. The City of La Quinta lies in a seismically active region of Southern California. Faults in the region include the San Andreas and Mission Creek faults located several miles to the north and west. The project lies within Groundshaking Zone III with Zone 12 being the most hazardous (Sources: Riverside County Comprehensive General Plan, La Quinta General Plan; La Quinta MEA). 06 11 A Preliminary Soil Investigation was conducted on the project site, in November 1984, by Buena Engineers, Inc. The report was prepared for Tract 20328, the Sand Pebble Country Club. This report identifies three soil types on the property, light brown slightly silty fine to course sand and gravel, light brown silt and very fine sand, and brown silty fine to medium sand with some gravel. The investigation included ten borings drilled in various portions of the project site. The report states that the bearing soils showed expansion indices of zero when tested. All indications are that the soils on the site will allow for the proposed development. According to the Soil Survey of Riverside County, California, Coachella Valley Area, prepared by the U.S.D.A. Soil Conservation Service in 1979, indicates that there are seven different types of soils present on the project site. These include: CdC - Carsitas gravely sand, RO - Rock outcrop, RU - Rubble land, MaB - Myoma fine sand, GbA - Gilman, fine sandy loam, Ip - Indio fine sandy loam, and CcC - Carrizo stony sand. Each of these: soil types has distinctive features and characteristics. The CdC soil is found on alluvial fans within slopes of 0 to 9 %. Runoff is slow, erosion hazard is moderate. The best uses of this soil are for watershed, wildlife habitat, recreation, and homesites. The shrink -swell potential is low. Corrosion to uncoated steel is high, but low to concrete. This soil tends to cave at cutbanks. The higher taxonomic classification for this soil is mixed, hyperthermic Typic Torripsamment. The RO soil type does not include any real soil, but rather rock outcrop consisting of granite, gneiss, mica, schist, and sandstone. These rocks are typically covered with Desert Varnish. The RU is found on very old alluvial fans. Riverwash is found alongside the main drainageways among the steep slopes. Desert Varnish is commonly found on rocks in the Rubble land. The best uses consist of watershed, wildlife habitat, and recreation. Vegetation in Rubble land commonly consists of brush, creosote bush, barrel cactus, bush sunflower, ocotillo, and some clumps of annual grass. MaB soil is found on level to gently sloping alluvial fans where it is merged with finer textured flood plain and basin soils. Runoff is very slow, and erosion hazard is slight. The best uses are for truck crops, citrus, grapes, alfalfa hay, homesites, and recreation. The shrink -swell potential is low. Corrosion of concrete is low. Uncoated steel will corrode easily in this soil. Cutbanks will cave in shallow excavations. The higher taxonomic classification of this soil is mixed, hyperthermic Typic Torripsamment. GbA soil is found in nearly level areas. Runoff is very slow. Erosion hazard is slight. Blowing soil potential is moderate. Best uses are for truck crops, alfalfa hav, citrus.. and grapes. The shrink -swell potential is low. Uncoated steel will easily corrode in this soil, however, concrete will not easily corrode. This soil type is subject to flooding. It is classified as coarse -loamy, mixed (calcareous) hyperthermic Typic Torrifluvent. 12 068 Ip soil is found on nearly level areas. Runoff is slow, erosion hazard is slight. Blowing soil potential is moderate. This soil is best used for farming. The shrink -swell potential is low. Uncoated steel will easily corrode, but concrete will not. It is classified as coarse -silty, mixed (calcareous) hyperthermic Typic Torrifluvent. CcC soil is found on alluvial fan slopes between 2 and 9 %. Runoff is slow, erosion hazard is slight. The best uses of this soil are for watershed and wildlife habitat. The shrink -swell potential is low. Cutbanks are subject to caving. There tend to be large stones in this soil. This soil tend to flood. The classification of this soil is sandy -skeletal, mixed, hyperthermic Typic Torriorthent (Source: Soil Conservation Service 1979). In 1986, a grading plan review of Tract 20328 was performed by Leighton and Associates. The report reviewed the geotechnical aspects of proposed grading at that time. In addition, a review of the Buena Engineers soil study was also conducted, as well as additional exploratory work to further evaluate the project soils. Conclusions of the study included that the types of classifications of soils exposed at the surface had not been fully mapped in order to better correlate grading recommendations; that the depth to ground water had not been determined; that the potential seismic hazards and effects had not been discussed in the earlier report; that lots proposed along the foot of the boulder strewn mountains could be subject to rock fall in the event of severe ground shaking by an earthquake; that depending on the degree of weathering, excavation of rock could become difficult, possibly requiring blasting in some areas; that premoistening should be anticipated to require a week or more prior to grading; and that certain overexcavation requirements for two- and three-story structures were not discussed in the earlier soils report (Source: Leighton and Associates 1986: 4-5). A letter update of the geotechnical investigation was conducted for the project site by Earth Systems Consultants, dated October 10, 1996. The letter addresses the areas previously graded by CVWD and the special attention needed to verify adequate compaction for density and moisture conditions. Proposed building pads located at the toe of the slope are discussed, including the recommended mitigation against rockfall hazard. This mitigation consists of constructing a swale near the toe of the slope and a fence on the house side of the swale. Site drainage is addressed in the letter with six recommendations offered: 1. Control of surface drainage is important to the successful development of the property. Surface drainage control should be provided throughout the completed project to protect the future stability of foundations and other site improvements. A positive gradient should be provided away from structures and should be directed towards an approved drainage discharge area in a nonerosive manner. 2. Down spouts from the roof of the houses should discharge collected rainwater onto splash blocks, adjacent paved areas, or be tied into a water -tight drainage 069 13 pipe, which would carry the collected water away from the houses to approved point(s) of discharge. 3. Rear and side yard surface drainage should not be allowed to be blocked From flowing to approved points of discharge by future sidewalks, patios, or landscaping. 4. Landscaping should be such that excess irrigation water is not allowed to pond on or near the structure or areas to be paved. Additionally, care should be taken so as not to over water landscaped area. Irrigation should be only sufficient to sustain plant life. 5. Failure to control excess moisture could result in settlement and soil erosion, which could compound the problem by rupturing water lines or other services and/or utilities, thus introducing additional moisture into the underlying soil. 6. No grading or excavating should be undertaken within the subject site without review by the geotechnical engineer (Source: Earth Systems Consultants 1996). The report concluded with the request that the project plans, be submitted to Earth Systems office for review of the geotechnical aspects to verify the recommendations contained in the Buena Engineers (1984) soils study and to provide supplemental recommendations as necessary. Another Geotechnical Update was prepared by Sladden Engineering, dated December 12, 1996. The report reviewed the rough grading plans for the proposed golf course. This review stated that the previous geotechnical reports contained useful information concerning site soil conditions and that the recommendations remain valid for the design and construction of the project. Clarification of previous recommendations was offered. A. Would the project result in or expose people to potential impacts involving seismicity: fault rupture? Less Than Significant Impact. There is an inferred fault line located as close as 1/2 mile south of the project site. This fault is considered potentially active, although no activity has been recorded for the last 10,000 years. A major earthquake along the fault would be capable of generating seismic hazards and strong groundshaking effects in the area. None of the inferred faults in La Quinta have been placed in an Alquist-Priolo Special Studies Zone. All homes developed on the proposed lots would be required to be constructed to current Uniform Building Code (UBC) seismic standards in order to mitigate risk of collapse to the extent feasible (Sources: Riverside County Comprehensive General Plan; City of La Quinta General Plan, La Quinta MEA, UBC). While accurate earthquake predictions are not possible, significant geologic. information and statistical analysis have been complied, analyzed, and published intensely by various agencies over the past 25 years. It has been reported that a 22% conditional probability occurrence for the 30-year period from 1994 to 2024 that a magnitude 7.5 event or 14070 greater would occur along the Coachella Valley segment of the San Andreas Fault. The primary risk to the project is the San Andreas Fault. The Coachella Valley Segment of the fault comprises the southern 115 km of.the fault zone. This segment has the longest elapsed time of any portion of the San Andreas Fault, last experiencing an event about 1690 AD based on USGS dating of trench surveys near Indio. The San Andreas Fault zone is considered to have characteristic earthquakes that ruptures each fault segment. The San Andreas Fault may rupture in multiple segments producing a higher magnitude earthquake (Source: Southland Geotechnical 1996). Fault rupture is not anticipated to occur at the project site because of the well -delineated fault lines through this region as shown on United States Geological Survey and California Division of Mines and Geology maps are not near the project site location. However, because the site is located in an area of high tectonic activity, the potential for surface rupture on undiscovered or new faults that may underlie the site can not be discounted (Source: Southland Geotechnical 1996:8). B. Would the project results in or expose people to potential impacts involving seismic ground shaking? Less Than Significant Impact. The future residential development will be subject to groundshaking hazards from regional and local events. The proposed project will bring people to the site who could be subject to these hazards. The Riverside County Comprehensive General Plan indicates that the lots are within Groundshaking Zone III. A Zone III is an area with moderate shaking qualities but less severe than a Zone 12 which is the highest level. Any homes constructed will be required to meet current seismic standards of construction to reduce, or mitigate to the extent feasible, the risk of structural collapse. The recommendations of the geotechnical report prepared for this project shall become conditions of approval. The land is generally suitable for the proposed project (Sources: La Quinta MEA). The primary seismic hazard at the project site is strong groundshaking from earthquakes along the San Andreas and San Jacinto (Source: La Quinta MEA; Riverside County Comprehensive General Plan). C. Would the project result in or expose people to potential impacts involving seismicity: ground failure or liquefaction? Less than Significant Impact. The proposed project is not in an area that is anticipated to be subject to ground failure hazards from earthquake or other events due to the distance from regional fault lines. The La Quinta General Plan indicates that the project site is not within a recognized liquefaction hazard area. The majority of the City has a very low liquefaction susceptibility due to the fact that ground water levels are generally at least 100 feet below the ground surface (Source: La Quinta MEA; Riverside County Comprehensive General Plan). 15 071 Liquefaction is not considered a potential hazard since the groundwater is believed to be deeper than 50 feet (the maximum depth that liquefaction is known to occur) (Source: Southland Geotechnical 1996:8). D. Would the project result in or expose people to potential impacts involving seismicity: seiche, tsunami or volcanic hazard? No Impact. The City is located in an inland valley, separated from the Pacific Ocean by mountain ranges, and would not be subjected to a tsunami. Lake Cahuilla, a man-made reservoir located in the southeast portion of the City, might experience some moderate wave activity as a result of an earthquake and groundshaking. However, the lake is not anticipated to affect this project in the event of a levee failure or seiche because the lake is on the other side of the Coral Reef Mountains (Source: La Quinta MEA; La Quinta USGS 7.5' Quad Map). E. Would the project result in or expose people to potential impacts involving landslides or mudflows? Potential Impact Unless Mitigated. The terrain within and surrounding the project site is that gently sloping alluvial plain abutting steep rocky hillsides. The parcel is adjacent to the Coral Reef Mountains, thus, there is a potential danger from landslides and rockfall at those areas adjacent to the toe of the slope. No mudflows are anticipated for this project, as the adjacent hills and mountains are formed of rocky granitic material. The general area of the project site is protected from flood waters by earthen training dikes and retention basins that are located at the southern boundary of the project, and existing retention basins and drainage channels within the project site. Additional on -site retention basins are proposdd for the project site that will be incorporated into the 18-hole gold course features (Source: La Quinta MEA; La Quinta USGS 7.5' Quad Map; TT 28470). The Earth System Consultants (1996) geotechnical report update prepared for the project states that there is a potential for rockfall hazard at the toe of the existing rock slopes. The Sladden Geotechnical Update report also stated that the potential for rockfall affecting the building pads along the toe of steep natural rock slopes should be acknowledged. The potential rockfall hazard appears to be limited to several building pads along the south and east edge of the site. The drainage swales indicated along the toe of the native rock slopes as indicated on the rough grading plans appears to approximately address rockfall hazards at this time. The rockfall hazard potential should be evaluated after rough grading and lot specific mitigation measures should be incorporated into individual fine grading plans and building layout determination. F. Would the project result in or expose people to potential impacts involving erosion, changes in topography or unstable soil conditions from excavation, grading, or fill? 16 072 Less Than significant Impact. The soils on the project site and geotechnical studies done in the vicinity of the project site show that the area is underlain by alluvial deposits of Pleistocene age. The soils on the site consists of Carrizo Carsitas sand in the alluvial fan, Myoma Fine Sand and Gilman Loam abutting Avenue 52, and Granite and Metamorphic Rock in the Coral Reef Mountains. Carsitas soils are generally used for citrus and grape growing, agricultural uses, wildlife habitat, recreational uses, and watershed areas. Carsitas and Gilman soils are permeable. Myoma soils are generally used for crops and homesites, and are excessively drained and include rapidly permeable soil. The MaD soil type is found on 5 to 15% slopes in alluvial fans. Runoff is slow and the erosion hazard is slight. The hazard of blow sand is high. This soil type is acceptable for home sites, recreation, and agriculture. The taxonomic class for this soil is mixed hyperthermic Typic Torrispaments. The MaD type is calcareous (Source: U.S.D.A. Soil Conservation Soil Survey of Riverside County, California - Coachella Valley Area; EA 92-240). Approximately 1,888,730 cubic yards of mass grading involving balanced cut and fill is projected for the project (Sources: TTM 28470 Grading Plan). Compliance with the recommendations of the grading plans and geotechnical studies for the project will ensure structural integrity of development on the site. Such compliance will be a condition of approval for the project. Monitoring of compliance will be provided by the City's Public Works Department staff. On December 17, 1996, the La Quinta City Council approved the issuance of an at -risk grading permit for the proposed golf course with the condition that the applicant post a bond equal to one-half the total cost of the grading in case the project is not approved or is modified at the public hearing so that restoration of the property can be performed. G. Would the project result in or expose people to potential impacts involving subsidence of the land? Less Than Significant Impact. The project site is not located in an area designated for subsidence hazards. Dynamic settlement results in geologically seismic areas where poorly consolidated soils mix with perched groundwater causing dramatic decreases in the elevation of the ground (Source: La Quinta MEA). H. Would the project result in or expose people to potential impacts involving expansive soils? Less Than Significant Impact. The underlying soils on the parcels have a low potential for expansion, thus future construction is not expected to be subject to problems from soil expansion. The City requires compliance with the Uniform Building Code and the recommendations of a soils investigation report prior to issuance of building and grading permits (Sources: U.S.D.A. Soil Conservation Service Soil Survey of Riverside County, California - Coachella Valley Area). 17 073 I. Would the project result in or expose people to potential impacts involving unique geologic or physical features? Potentially Significant Unless Mitigated. The Coral Reef Mountains represent a unique geologic feature in the La Quinta area. This unique feature is located within the project site boundaries and could be affected by the proposed project. The proposed golf tee area that is elevated into the mountain and the six proposed homesites that at the southern high cove area of the project may require grading measures that will cut into the mountain. A geotechnical report prepared for a previous project on this project site stated that .."Depending on the degree of weathering, excavation of rock could become difficult, possibly requiring blasting in some areas (Sources: Leighton and Associates 1986:5, La Quinta MEA; USGS La Quinta 7.5' Quad Map; Site Survey; TT 28470). The applicant has stated that no blasting will be utilized. No blasting would be permitted by the City for this project due to the impacts to the wildlife and associated habitat within the Coral Reef Mountains, as well as potential geologic hazards. 3.4 WATER Regional Environmental Setting Groundwater resources in the La Quinta area consist of a system of large aquifers (porous layers of rock material containing water) and groundwater basins separated by bedrock or layers of soil that trap or retain groundwater. La Quinta is located above the Coachella Valley Groundwater Basin which is the major water supply for the potable water needs of the City as well as a significant supply for the City's nonpotable irrigation needs. Water is pumped from the underground aquifer via domestic water wells in the City operated and administered by the Coachella Valley Water District (CVWD). La Quinta is located primarily in the lower Thermal Subarea of the groundwater basin. The Thermal Subarea is separated into the upper and lower valley sub -basins near Point Happy, located southwest of the intersection of Washington Street and State Highway 111. CVWD estimates that approximately 19.4 million acre feet of water is stored within the Thermal Subarea which is available for use. Water pumped from the aquifer is treated and distributed to users through the existing (potable) water distribution system. Wager is also pumped for irrigation purposes to water golf courses and the remaining agricultural uses in the City. Water supplies are augmented with surface water from the Colorado River transported via the Coachella Canal. The quality of water in the La Quinta area is highly suitable for domestic purposes. However, chemicals associated with agricultural production in nearby areas and the use of septic tanks in the Cove area affect groundwater quality. Groundwater is of marginal to poor quality at depths of less than 200 feet. Below 200 feet, water quality is generally good and water depths of 400 to 600 feet are considered excellent. 18 074 Percolation from the tributaries of the Whitewater River flowing into La Quinta from the Santa Rosa Mountains provide a natural source of groundwater replenishment. Artificial recharging of groundwater will be a necessary in the near future. Surface water in La Quinta is comprised of Colorado River water supplied via the Coachella Canal and stored in the Lake Cahuilla reservoir; lakes in private developments which are comprised of canal water and/or untreated groundwater; and the Whitewater River and its tributaries. The watersheds in La Quinta are subject to intense storms of short duration which result in substantial runoff. The steep gradient of the Santa Rosa Mountains accelerates the runoff' flowing in the intermittent streams that drain the mountain watersheds. La Quinta is protected from this runoff by the existing flood control facilities located throughout the City. One of the primary sources of surface water pollution is erosion and sedimentation from development construction and operation activities. Without controls, total dissolved solids (TDS) can increase significantly from the development activities. The Clean Water Act requires all communities to conform to standards regulating the quality of water discharged into streams, including stormwater runoff. The National Pollutant Discharge Elimination System (NPDES) has been implemented as a two-part permitting process., for which the City of La Quinta participates. La Quinta is protected from storm water runoff by a stormwater system designed by Bechtel for the Coachella Valley Water District to protect currently developed and potentially developable areas of the City from damage during a major rainflood event. The system project was based on a flood control plan for the general area developed . by Bechtel for the District in 1970. Construction was completed in November 1986 (Source: Bechtel Civil, Inc. 1989:1). Local Environmental Setting The project site does not have any natural standing water. Lake Cahuilla, a man-made reservoir is located approximately two miles to the southeast, on the other side of the Coral Reef Mountain. The Whitewater River channel is located slightly over 3 miles to the north of the project site, but is dry except during seasonal storms. The La Quinta Stormwater Channel is located approximately 1 mile to the north is a part of the community -wide network of flood control facilities. The City currently has only limited areas which are still subject to storm water flow or flooding. Flood prone areas are designated with a specific zoning district (Watercourse, Watershed and Conservation Areas: W-1). The intent of this zoning district is to allow development in flood prone areas based upon the submittal of a drainage and storm'A'ater control plan. The City also implements flood hazard regulations for development within flood prone areas. 075 19 Existing flood control facilities on the proposed project site are a part of the City-wide Stormwater Project - East La Quinta System. The facilities were designed by a previous developer's engineer, with the design reviewed by Bechtel. Construction of these facilities was completed in mid-1988, by E. L. Yeager Construction Company. The East La Quinta System intercepts and controls runoff originating in the drainage area in the foothills east and southeast of Avenida Bermudas, and from the presently developed area of the City of La Quinta south of Calle Durango. The system consists of the Upper Training Dike, Calle Tecate Detention Basin, East La Quinta Channel, Avenida Bermudas Detention Basin, the proposed Tradition project site facilities, and a 60-inch diameter buried stormwater conduit. The detention basin on the project site has a storage volume of about 520 A.F. below El. 59, while maintaining a minimum one foot freeboard (Source: Bechtel Civil, Inc. 1989), A Hydrology/Hydraulic Report was prepared for the project site, in October 1996, by Keith International, Inc.. The project proposes areas north of the detention basin to provide for on site retention. Runoff from the residential, clubhouse, and golf course areas will be conveyed to depressions located within the golf course. The retention areas have been integrated into the golf course grading plan as golfing amenities. The basin sizing is based on the total run off from a 24 hour - 100 year event. Five basins are proposed with the following locations and capacities: Basin Hole # Basin Capacity 1 16 7.90 acre feet 2 Driving Range 83.50 acre feet 3 4 14.50 4 2 & 3 31.30 5 1 41.80 (lake) The hydrology study modeled the 100-year and 10 year storm events to determine which storm will generate the greatest storm volume. The results will be utilized to determine the size of the retention basins. It was determined that historic flows are retained onsite, thus the proposed development must retain all of the flows onsite (Source: Keith International. Inc. 1996). A. Would the project result in changes in absorption rates, drainage patterns, or the rate and amount of surface runoff'.' Less Than Significant Impact. An approved drainage plan will be required prior to issuance of a grading permit, based upon the recommendations and results of the Drainage study prepared by Keith International, Inc., October 1996. There will be changes in absorption rates, but not drainage patterns or surface runoff as a result of the proposed project. The absorption rate will be altered by the paving of streets, building of homes., and landscaping of yards, landscape lots, and the golf course. The traditional historical 20076 drainage pattern will be maintained as is required by the City. Retention basins and other facilities will catch and hold the surface runoff storm water on -site. The proposed Tradition project (241 lots) is significantly less dense than the former "Heritage" project (330 homes), and the even earlier project "Crystal Canyon" with 890 units, reducing the runoff rate and flood volumes to these existing structures. Since the on site development has a reduced density (compared with the original design assumptions used for the Heritage Country Club) with fewer homes and increased landscaping, peak runoff flows and flood volumes will also be reduced (Keith International, Inc. 1996). B. Would the project result in exposure of people or property to water -related hazards such as flooding? Less Than Significant Impact. The project site is partially within the AO designated flood hazard area in the northeastern portion of the project site. The AO designation is the 100 year flood plain FIRM zone in which the hazard factors have been determined. There are existing on -site flood control or drainage facilities on the property, that were constructed by the Coachella Valley Water District as part of the East La Quinta Storm Drain system. These improvements were coordinated with an earlier planned golf course development, formally known as the "Heritage Country Club". The proposed project intends to fully utilize these existing improvements and integrate them into the overall development and drainage system. The existing structures and basins will remain in palace. The new design will maintain all structure capacities and volumes. The proposed Tradition project is significantly less dense than the earlier "Heritage Country Club", reducing the runoff rate and flood volumes to these existing structures. The proposed development has submitted a drainage plan which will include 5 additional retention basins and drainage improvements onsite (Source: Keith International, Inc. 1996). C. Would the project result in discharge into surface waters or other alteration of surface water quality (e.g. temperature, dissolved oxygen or turbidity)? Less Than Significant Impact. Runoff from the project site will be required to be directed into the five proposed retention basins and be controlled by both existing and proposed drainage facilities. There are no existing bodies of surface water on or adjacent to the project site. Five lakes are proposed for the golf course which will also function as retention areas (Source: Site Survey; Coachella Valley Water District; TT 28470). D. Would the project result in changes in the amount of surface water in any water body? Less Than Significant Impact. There are no bodies of surface water on the subject parcel. Five man-made lakes within the golf course are proposed. Runoff water is designed to flow into these lakes. Although a substantial amount of runoff volume will come from the Coral Reef Mountains, it is not expected to significantly impact surface water. The size 07 c 21 of the project represents a sizable percentage of the drainage tributary area for the City (Source: Site Survey; Keith International, Inc. 1996). E. Would the project realest in changes in currents, or the course or direction of water movements? Less Than significant Impact. The City of La Quinta does not have any substantial natural bodies of water or rivers. There are many small man-made lakes and ponds on golf courses within the City. A few agricultural reservoirs are still in use, as well. The La Quinta Evacuation Channel is a man-made stormwater channel that is usually dry except for runoff from seasonal storms. The future development of the project site with the proposed land use designations will not affect, to a significant degree, any existing drainage corridor (Source: Site Survey; TTM 28470; La Quinta MEA). F. Would the project result in changes in quantity of ground waters, either through direct additions or withdrawl, or through interception of an aquifer by cuts or by excavations? Less Than Significant Impact. Water supply in the City is derived from groundwater and supplementary water brought in from the Colorado River. The proposed development of the project site will consist of single family units and the golf course. Potable water to service this development will most likely come from existing groundwater wells in the near vicinity and a new well to be located by the third green. The proposed golf course will be irrigated from existing wells on the project site. These wells were formerly used for agricultural irrigation and are in working order. The Planning Standard for residential water consumption is 315 Gal/DU/Day. The day water consumption would be 241 units x 315 Gal/DU/Day = 75,915 Gallons for the single family residential use. Other uses proposed for the project include the rehabilitation of the historic mansion for use as administrative offices, the future construction of a clubhouse, maintenance building, half- way house, and cart barn. The Coachella Valley Water District has stated that it will furnish domestic water and sanitation service to the project, but will need additional facilities to provide for expansion of its domestic water system. These new facilities may include wells, reservoirs, and booster pumping stations. Water from the Coachella Canal is also available for irrigation of the golf course and green belt areas that are within Improvement District No. 1 (Sources: La Quinta MEA; Application Materials, Coachella Valley Water District). G. Would the project result in altered direction or rate of flow of groundwater? Potentially Significant Unless Mitigated. The proposed subdivision might have a significant effect on groundwater wells. It is not anticipated that there will be any significant alteration to the direction of flow of the groundwater supply, however, the rate of flow may be impacted due to high demand for water. No deep cuts are proposed with this project that would reach the depth of the groundwater, other that the drilling of a new water well. The proposed well would reach a depth of potable water which would impact 078 22 the local groundwater rate of flow and possibly direction (Source: Tentative Tract 28470). The Coachella Valley Water District stated that local groundwater supplies may not be adequate to supply long-term domestic or irrigation demands. Groundwater pumping will be subject to a replenishment assessment to provide a funding mechanism for importation of additional water supplies (Source: CVWD letter of Nov. 14, 1996). H. Would the project result in impacts to groundwater quality? Less Than Significant Impact. Future development of the project site will include concrete and asphalt pavement of portions of the site, and golf course pathways. This pavement will reduce the absorption ability of the ground. Storm water runoff will be discharged into on -site basins channels, lakes, and pipes. Following a heavy rain, contaminates could be transported into the basins or into the nearby storm drains that could contribute to groundwater and/or surface water pollution. However, this potential impact is anticipated to be less than significant. Golf course lake best management practices will be required to be implemented in order to minimize surface water pollution. The applicant will be required to line the golf course lakes with an impermeable product with a hard edge grouted in. 3.5 AIR QUALITY Regional Environmental Setting The Coachella Valley is under the jurisdiction of the South Coast Air Quality Management District (SCAQMD), and in particular, the Southeast Desert Air Basin (SEDAB) division. SEDAB has a distinctly different air pollution problem than the South Coast Air Basin (SCAB). A discussion of the jurisdictional organization of SCAQMD and requirements is found in the La Quinta MEA. The air quality in Southern California region has historically been poor due to the topography, climatological influences, and urbanization. State and federal clean air standards established by the California Air Resources Board and the U. S. Environmental Protection Agency (EPA) are often exceeded. The SCAQMD is a regional agency charged with the regulation of pollutant emissions and the maintenance of local air quality standards. The SCAQMD samples air at over 32 monitoring station in and around. the Basin. According to the 1989 South Coast Air Quality Management Plan, SEDAB experiences poor air quality, but of a lesser extent than the SCAB. Currently, the SEDAB does not meet federal standards for ozone, carbon monoxide, or particulate matter (PM- 10). In the Coachella Valley, the standard for PM-10 is frequently exceeded. PM-10 is a particulate matter 10 microns or less in diameter that becomes suspended in the air due to winds, grading activity, and by vehicles traveling on unpaved roads, among other causes. 23 079 Local Environmental.Setting The City of La Quinta is located in the Coachella Valley, which has an and climate, characterized by hot summers, mild winters, infrequent and low annual rainfall, and low humidity. Variations in rainfall, temperatures, and localized winds occur throughout, the valley due to the presence of the surrounding mountains. Air quality conditions are closely tied to the prevailing winds of the region. The City of La Quinta is subject to the SCAQMD AQMD, a plan which describes measures to bring the SCAB into compliance with federal and state air quality standards and to meet California Clean Air Act requirements. The General Plan for the City contains an Air Quality Element outlining mitigation measures as required by the Regional AQMP. The City is located within Source Receptor Area (SRA) 30, which includes two air quality monitoring stations, one located in the City of Palm Springs, and the other in the City of Indio. The Indio station monitors conditions which are most representative of the La Quinta area. The station has been collecting data for ozone and particulates since 1983. The Palm Springs station monitors carbon monoxide in addition to ozone and particulate and has been in operation since 1985. A. Would the project violate any air standard or contribute to an existing or projected air quality violation? Potentially Significant Unless Mitigated. The South Coast Air Quality Management District CEQA Air Quality Handbook indicates that the threshold for significance in single family development is at 170 units. Above 170 units may result in a significant impact to the air quality, unless mitigation is implemented. To assess the potential impacts of this project, a computerized air quality analysis was conducted by Community Development staff. The assessment indicated that the proposed project would produce temporary construction emissions during the construction of the 241 single family home sites. Emissions produced during construction would vary daily depending on the type of activity. Emissions would be generated during grading, framebuilding and other construction activities. Grading and construction would result in a less than significant air quality impact (Source: Screen.xls). The table below quantifies the emissions: Construction Emissions: Project Emissions (lbs/day) ROG NOX CO PM10 40.1 64.5 253.2 146.7 SEDAB Thresholds (lbs/day) ROG NOX CO PMIO 75 100 550 150 (Source: SCREEN.XLS) ZM 24 Implementation of the proposed project would result in long-term direct and indirect: air pollutant emissions. Direct emissions would be generated by the use of motor vehicles and natural gas appliances. Indirect emissions would be generated during the use of electricity. No wood burning emissions would be generated by the proposed project except for residential fireplaces. Emissions from motor vehicle operation are anticipated to resu;.t in the greatest long-term air quality impact associated with development of the proposed project. The report concludes that the significance thresholds would not be exceeded for ROG, CO, PM-10, and Nox. This impact is considered to be less than significant. The proposed project would not contribute significantly to regional or local air quality impacts. The following construction emission mitigation measures will reduce Nox emissions: 1. Configure construction parking to minimize traffic interference. 2. Provide temporary traffic control during busy construction periods to improve traffic flow. 3. Schedule construction activities that affect traffic flow to off-peak hours. 4. Suspend use of all construction equipment operations during second stage smog alerts. 5. Prevent construction trucks from idling longer than two minutes. 6. All construction equipment shall be maintained to prevent visible soot from reducing light transmission through the exhaust stack exit by more than 20 percent for more than 3 minutes per hour and use low -sulfur fuel as required by SCAQMD regulation. However, even with the implementation of the above measures, the construction -related Nox emissions would continue to exceed SCAQMD thresholds. Therefore, construction emissions of Nox would be considered significant and unavoidable. To mitigate for the over-all air quality impact that may result for the project, the following SCAQMD mitigation measures will be required: Best available mitigtion measures for construction: 1. Low emission on -site mobile equipment (tractor, scraper, dozer, etc.) will result in an approximate 60% emission reduction efficiency. 2. Energy use - use electricity from power plants or clean fuel generators rather than temporary diesel powered generators. This will reduce emissions by 50 to 98%. 3. Fugitive dust from roads - Pave construction roads that have a traffic volume of less than 50 daily vehicle trips to reduce fugitive dust by 90 to 99%. 25 Best available mitigation measures for operation activities: Residential energy use: 1. Use solar or low emission water heaters for a 40% emission reduction. 2. Use central water heating systems (emission reduction not quantified) 3. Use built-in energy efficient appliances for a 10 to 20% emission reduction. 4. Building orientation should be to the north for natural cooling (efficiency not quantified) 5. Provide shade trees to reduce heat for a 55% energy reduction. 6. Use energy efficient and automated controls for air conditioners for a 30% energy reduction. 7. use double -glass paned windows for a 20% energy reduction. Clubhouse: Construction phases: 1. Implement on -site circulation plan in parking lots to reduce vehicle queuing (emission reduction not quantified) Energy use: 1. use energy efficient low sodium parking lot lights for a 55% energy reduction. 2. Use lighting controls and energy efficient lighting for a 60 to 75 % energy reduction. 3. Require recycling bins in addition to trash bins and contract for recycling services. 4. Increase walls and attic insulation beyond Title 24 requirements for a 5 to 9 % energy reduction. 5. use light colored roof materials to reflect heat. 6. use building materials that do not require use of paints and solvents for an 80 to 100% emission reduction. 7. Provide dedicated parking spaces with electrical outlets for electrical vehicles. With the implementation of the above recommended mitigation measures, the potentially significant air quality impacts will be reduced to a level of insignificance (Source: SCAQMD CEQA Air Quality Handbook). B. Would the project expose sensitive receptors to pollutants? Less Than Significant Impact. Sensitive receptors include schools, day care centers, parks and recreation centers, medical facilities, rest homes, and other land uses that include concentration of individuals recognized as exhibiting particular sensitivity to air pollution. The adjacent land uses consist of residential to the west and north, residential development to the northeast, and open space to the south and east. The closest schools located to the proposed project are the new Adams Elementary School located north of 26 Calle Tampico and west of Washington Street, and the La Quinta Middle School and Truman Elementary School located east of Washington Street and north of Avenue 50. The closest existing public park is the Fritz B. Burns Park located near the northwest corner of the project. The Ambient Air Quality Standards (AAQS) are designed to protect that segment of the public most susceptible to respiratory distress or infection, referred to as "sensitive receptors." (Sources: La Quinta General Plan; Site Survey). C. Would the project alter air movements, moisture, temperature, or cause any change in climate? Less Than Significant Impact. The proposed subdivision is not anticipated to result in any significant impact upon this issue area. All proposed 241 home sites will be required to meet height and setback requirements, maintaining a low profile. Two-story units may be approved for construction. '_Moisture content may increase as the golf course and individual yards are planted and irrigated. Swimming pools would add to the moisture index of the area. There are no significant climatic changes anticipated with the filture development of the parcels. There is no feasible mitigation for this issue other than to not construct the golf course or to reduce the golf course to 9-holes. The applicant is not proposing any alternative designs for this project. D. Would the project create objectionable odors? Less Than Significant Impact. The proposed project will not result in development which may create objectionable odors, such as waste hauling or chemical products. Vehicles traveling on nearby and internal project streets generate gaseous and particular emissions that may be noticeable on the project site. However, these would be short-term odors that should dissipate quickly (Source: Site Survey). 3.6 'TRANSPORTATION/CIRCULATION Regional Environmental Setting La Quinta is a desert community of over 18,600 permanent residents. The City is 31.18 square miles in size, with substantial room for development. The existing circulation system is a combination of early roadwork constructed in the 1930's by Riverside County and new roadways since incorporation of the City in 1982. Key roadways include State Highway 111, Washington Street, Jefferson Street, Fred Waring Drive, and Eisenhower Drive. Traffic volumes in La Quinta experience considerable seasonal variation, with the late - winter, early spring months representing the peak tourist season and highest traffic volumes. There is a relatively low incidence of automobile accidents at the intersection of Washington Street and Avenue 52. According to the City Engineering Department, there were 15 vehicular accidents at this intersection between 1988 and 1989 (Source: Traffic Collision Data, City of La Quinta; La Quinta General Plan). Between January 1993 and 27 093 December 1994, there were six accidents. In 1995, there were two accidents. And, in 1996, there was one accident between January and March (Source: SWITRS, Public Works Department). Existing transit service in La Quinta is limited to three regional fixed -route bus routes operated by Sunline Transit Agency. One bus route along Washington Street connects the Cove and Village areas with the community of Palm Desert to the west. Two lines operate along Highway 111 serving trips between La Quinta and other communities in the desert. There are only a few existing pedestrian, bicycle and equestrian facilities in La Quinta, however, these systems will be expanded as the City grows. These facilities, both existing and future, are designated in the La Quinta General Plan. Local Environmental Setting The subject project site is located south of the southern terminus of Washington Street, east of Avenida Bermudas. Washington Street is classified as a major arterial with a 120 foot right-of-way. The intersection of Washington Street and Avenue 52 is currently controlled by 4-way stop signs. Avenida Bermudas is classified as a secondary arterial with an 80-foot right-of-way. Avenida Bermudas is located along the western boundary of the project site. It is designated as a bikeway corridor. The La Quinta General Plan gives design standards for the various street classifications. According to the standards for major arterials, the projected buildout traffic volume for Washington Street, north of the subject property will exceed the volume range. It is projected that Washington Street will experience a daily traffic volume of 52,600 south of Avenue 50, at buildout, providing a Level Of Service D (LOS-D). LOS-D has unstable flow with poor progression and frequent cycle failures. This is considered the limit of acceptable delay. LOS F has oversaturation with arrival flow rates exceeding the capacity of the intersection and is considered unacceptable to most drivers. A more detailed explanation of buildout traffic conditions and levels of service is found in the La Quinta General Plan. The current average daily traffic flows for Washington Street, south of Avenue 50 are 13,697 vehicles per day and 16,354 vehicles per day south of Eisenhower Drive. The existing traffic volume at the intersection of Avenue 52 and Washington Street is 7,982 vpd with 4,271 vpd entering or leaving Washington Street. This intersection has met warrants for a signal (Source: Public Works Department). A. Would the project result in increased vehicle trips or traffic congestion? Potentially Significant Unless Mitigated. Housing units for this project site are less than what was used in the "build -out" traffic model for the 1991 La Quinta General Plan. Potential development The project is incorporating mitigation improvements as identified and required by the General Plan of the project site is forecasted to generate 28 084 approximately 4,588 daily vehicle trips from the 241 single family lots, the 271 acre golf course, and approximately 1,000 square feet of administrative office space within the historic hacienda (Source: Trips.xls; Keith International, Inc.). Additional daily vehicle trips may be generated by the proposed buildings. B. Would the project result in hazards to safety from design features (e.g. sharp curves or dangerous intersections) or incompatible uses (e.g. farm equipment)? Less Than Significant Impact. There are no identified hazards from design features in the existing roadways or the proposed circulation system. Automobile, motorcycle, and golf cart traffic are the only types of vehicles that typically use private residential streets, with the exception of delivery trucks. A golf cart path system will be constructed within the country club (Source: TTM 28470). C. Would the project result in inadequate emergency access to nearby uses? Less Than Significant Impact. Future development of the project site would not be permitted to obstruct emergency access to surrounding land uses. This requirement would be made a part of project conditions of approval. Review of development plans by the Fire Department did identify that a secondary access is required along Avenida Bermudas. Additional emergency accesses will also be required by the City for the project. D. Would the project result in insufficient parking capacity on -site or off -site? Less Than Significant Impact. Parking will be required for each custom-built housing unit as it is constructed, which will consist of a two to three car garage, and tandem parking in the driveway. On -street parking will not be available (Source: La Quinta Zoning Ordinance; La Quinta Subdivision Ordinance; Application Materials). Parking for the clubhouse, maintenance yard, and administrative offices will be required to meet the parking standards of the Zoning Ordinance. The applicant proposes a total of 158 parking spaces, four of which are designated for handicapped vehicles. The Zoning Ordinance requires a total of 129 spaces for the proposed uses. E. Would the project result in hazards or barriers for pedestrian or bicyclists? Less Than Significant Impact. The east side of Avenida Bermudas and the east side of Washington Street are designated bikeway corridors. It is anticipated that hazards to bicyclists and pedestrians will not be increased significantly as a result of the proposed development (Source: La Quinta General Plan). The bicycle and pedestrian corridors will be outside of the project perimeter wall, along the east side of Avenue Bermudas. There will not be any identifiable increase in hazards than currently exist. 29 `, 8 F. Would the project result in conflicts with adopted policies supporting alternative transportation (e.g. bus turnouts, bicycle racks)? No Impact. Bicycle racks are only required for commercial land uses. The Zoning Ordinance does not require bicycle racks for residential projects. The proposed project will be reviewed by the Sunline Transit Agency for needed bus turnouts (Source: La Quinta Zoning Ordinance). Bicycle racks should be provided for the Clubhouse. G. Would the project result in rail, waterborne or air traffic impacts? No Impacts. There is no rail service in the City of La Quinta. The closest rail lime is approximately six miles to the north of the project site. There are no navigable rivers or waterways, or air travel lanes or airports within the City. Thus, there will be no impacts upon these issues. The closest airports are the Bermuda Dunes Airport, a small private facility located just south of Interstate 10, approximately six miles north of the project site and the Thermal Airport, located approximately six miles southeast of the project:, on Airport Boulevard in the Thermal area (Sources: La Quinta MEA; USGS La Quinta 7.5' Quad Map, Site Survey). 3.7 BIOLOGICAL RESOURCES Regional Environmental Setting The City of La Quinta lies within the Colorado Desert regional environment. Two ecosystems are found within the City, the Sonoran Desert Scrub and the Desert Transition. The disturbed environments within the City are classified as either urban or agricultural. A detailed discussion of these ecosystems is found in the La Quinta Master Environmental Assessment (1992). Local Environmental .Setting The project site is located in the Sonoran Desert Scrub ecosystem. Typically, undeveloped land within this ecosystem is rich in biological resources and habitat. However, the project site has been disturbed by agriculture and mass grading in the distant and recent past. The Sonoran Desert Scrub is the most typical environment found in the Coachella Valley. It is generally categorized as containing plants which have the ability to economize water uses, go dormant during periods of drought, or both. Cacti are very common in these areas due to their ability to store water. Other plants root deeply and draw upon water from considerable depths. The variations of desert vegetation result from differences in the availability of water. The most dense and lush vegetation in the desert is found where groundwater is most plentiful. The Sonoran Scrub areas are considered habitat for a number of small mammals. These animals escape the summer heat through their nocturnal and /or burrowing tendencies. 30 686 Squirreis, mice and rats are all common rodent species in this environment. The black - tailed hare is a typical mammal. Predator species include kit fox, coyote, and mountain lion in the higher elevations. The largest mammal species found in this area is the Peninsular Bighorn sheep which is found at the higher elevations of the Santa Rosa and San Jacinto Mountain ranges. Birds and amphibians/reptiles can also be found in the Sonoran Scrub area. The Desert Transition areas are found in the alluvial fan areas and slopes of the surrounding mountains. The transition is gradual and involves an intermingling of vegetation types typically found in the Desert Scrub ecosystem and the Pinon-Juniper Woodland near the top of the Santa Rosa Mountains. The plant species in the desert transition zone benefit from slightly higher rainfall. Where creosote bush and bur. -sage dominated in the desert scrub areas, cacti become more abundant and ocotillo dominate on the upper portions of alluvial fans, bajadas, and rocky mountain slopes. The La Quinta General Plan identifies the property as being within the habitat of the Fringe -toed Lizard. In addition, there have been sightings of the endangered plant, California ditaxis, in the general area of the project (Sources: Site Survey; La Quinta MEA). A. Would the project result in impacts to endangered, threatened or rare species or their habitats (including but not limited to plants, fish, insects, animals, and birds)`?' Potentially Significant Unless Mitigated. The La Quinta Master Environmental Assessment identifies the project site as within the habitat of the Coachella Valley Fringe Toed Lizard, and the California ditaxis. The project site is not within the mitigation fee area for the Coachella Valley Fringe -toed Lizard Habitat Conservation Plan, even though a portion of the project area is within the lizard's traditional habitat. There is no required mitigation for this species for this project. The California ditaxis is considered a "Species of Special Concern" and the State of California has ranked the plant "Endangered." The property has been highly disturbed since 1902 when date trees, and later citrus trees, were planted on the property. Over the years, the agricultural use of the property expanded. In 1988, the Coachella Valley Water District constructed Mood control facilities on the project site which involved mass grading. Due to the extensive and lengthy disturbance of the property, no natural undisturbed plant communities remain on the property. The Prairie Falcon has been observed in the Santa Rosa Mountains to the south of this project site. The falcon is listed as a Species of Special Concern. The California desert is thought to support the largest remaining falcon population although new sightings have not been noted in the La Quinta area in recent years (Source: EA 92-240). The Bighorn Sheep have also been sighted in the Santa Rosa Mountain Range, of which the Coral Reef Mountains are a part of. The Bureau of Land Management Santa Rosa 31 08 7 Mountains Wildlife Habitat Management Plan states that the largest population of Peninsular Bighorn Sheep is found in the Santa Rosa Mountains. The plan requires. that the public use must be adjusted to minimize impacts on the wildlife habitat area. Summer bighorn use areas, particularly those around water sources, are the most sensitive to human impacts. This project is north of the BLM habitat area, thus there are no anticipated impacts to the bighorn sheep from the proposed project. So as not to create barriers across habitat corridors for migrating species, development of this property should be limited to areas within the residentially -zoned district with no development in the Hillside Conservation designated areas. The mountainous areas should be retained as open space and either managed by the City or a non-profit organization. The hillside areas should not be fenced in order to permit access across the open space areas by native and migrating wildlife (Source: EA 92-240). B. Would the project result in impacts to locally designated species (e.g. heritage trees)? Less Than Significant Impact. There are no locally designated biological resources within the City of La Quinta. All significant biological resources are designated by the California Department of Fish and Game or the U.S. Fish and Wildlife Service (Source: La Quinta MEA). There is a wind row of several large eucalyptus trees along Old Avenue 52 that are of historic significance. Staff has required that a qualified arborist evaluate the trees for preservation and incorporation into the project. The project proposes to remove the dead trees and retain about 14 trees. C. Would the project result in impacts to locally designated natural communities (e.g. oak forest, coastal habitat, etc.)? No Impact. There are no locally designated natural communities found in or near the project site. Some of the surrounding parcels are developed with homes, a golf course, or roadways. The parcels have been disturbed by off -road vehicles and farming activities to the extent that there are no existing or relic plant communities left (Source: La Quinta MEA; Site Survey). D. Would the project result in impacts to wetland habitat (e.g. marsh, riparian, and vernal pool)? No Impact. There are no natural wetlands, marshes, riparian communities, or vernal pools on the project site or nearby. It is possible that during the last stand of the ancient Lake CahuilIa, the project site might have been within a marsh community along; the lakeshore or may have been partially inundated by the lake. However, the lake dried approximately 500 years ago and the land has been dry since. The project site has become covered by sedentary deposits since the prehistoric lake dried (Sources: Site Surveil; La Quinta MEA; Draft Historic Context Statement for City of La Quinta). E. Would the project result in impacts to wildlife dispersal or migration corridors? oss 32 Less Than Significant Impact. The project site is surrounded by developed parcels on these sides which have effectively cut off migration corridors to and from the project site except to and from the Coral Reef Mountains. Wildlife corridors are still open in the Coral Reef :Mountains which provide access to the higher mountains to the south. (Source: La Quinta MEA; Site Survey). 3.8 ENERGY AND MINERAL RESOURCES Regional Environmental Setting The City of La Quinta contains both areas of insignificant and significant Mineral Aggregate Resource Areas (SMARA), as designated by the State Department of Conservation. There are no known oil resources in the City. Major energy resources used in La Quinta come from the Imperial Irrigation District (IID), Southern California Gas Company, and various gasoline companies. Local Environmental Setting There are no oil wells or other fuel or energy producing facilities or resources on or near the project site. While the project site is undeveloped, there is no significant resource to be mined, such as rock or gravel. The project site is located within MRZ-1 and MRZ-3. The MRZ-1 designation is applied to those areas where adequate information indicates that no significant mineral despots are present or where it is judged that little likelihood exists for their presence. The MRZ-3 designation is for those areas containing mineral deposits the significance of which cannot be evaluated from available data. The northern portion of the project is within an area of Prime Agricultural Soils (Source: La Quinta MEA; Site Survey). A. Would the project conflict with adopted energy conservation plans? No Impact. The City of La Quinta does not have an adopted energy plan. However, the City does have a Transportation Demand Management ordinance in place that focuses on the conservation of fuel and travel to large commercial centers. The Housing Element contains requirements for efficiency in housing construction and materials, thus reducing energy consumption. Future development will be required to meet Title 24 energy requirements. B. Would the project use non-renewable resources in a wasteful and inefficient manner? Less Than Significant Impact. Natural resources that may be used by this proposed project include air, mineral, water, sand and gravel, timber, energy, and other resources needed for construction and operation. Title 24 requirements shall be complied with for energy conservation. Any landscaping will also be required to comply with the City's 089 33 landscape water conservation ordinance as well as the requirements of the Coachella Valley Water District (Source: La Quinta MEA; Water Conservation Ordinance; Coachella Valley Water District). 3.9 RISK OF UPSET/HUMAN HEATH Regional Environmental Setting Recent growth pressure has dramatically increased the City's exposure to hazardous materials. Such exposure to toxic materials can occur through the air, in drinking water, in food, in drugs and cosmetics, and in the work place. Although large scale, hazardous waste generating employment is not yet present in the City of La Quinta, the existence of chemicals utilized in dry cleaning operations, agricultural operations, restaurant kitchen cleaning, landscape irrigation and exposure to large scale electrical facilities may pose significant threats to various sectors of the population. Currently, there are no hazardous disposal waste sites located in Riverside County, although transportation of such material out of, and around, La Quinta takes place. Local Environmental .Setting In order to comply with AB 2948-Hazardous Waste Management Plans and Facility Siting Procedures, the City of La Quinta adopted Ordinance 184 consisting of a Hazardous Waste Management Plan. The project site has not been used for any type of manufacturing or industry, and there has not been any known dumping of hazardous substances on the property (Sources: Site Survey; Aerial Photos). A. Would the project involve a risk of accidental explosion or release of hazardous substances (including not limited to oil, pesticides, chemical, or radiation)? Less Than Significant Impact. There is a minimal risk of exposure from swimming pool chemicals and pesticides that may be used by residents of the future homes within the project. No other risks are anticipated by the land division, future custom homes, clubhouse. or other proposed structures. B. Would the project involve possible interference with an emergency response plan or emergency evacuation plan? Less Than Significant Impact. Construction activities will be confined to the project site, except for minimal off -site work -as is necessary for project roadways, curbs, and gutters. These activities will not be permitted to interfere with emergency responses to the site or surrounding areas nor will it obstruct emergency evacuation of the area. Needed measures to divert and control traffic shall be implemented whenever required (Source: Site Plan). Emergency accesses will be required for the project to meet the requirements of the Fire Department. 34090 C. Would the project involve the creation of any health hazard or potential health hazards? No Impact. There are no anticipated health hazards associated with the proposed project beyon -'-.(ise normally associated with a construction project (Source: Site Plan). D. Would the project involve exposure of people to existing sources of potential health hazards? No Impact. There are no identifiable health hazards on the project site. The proposed development is not expected to create any health hazards. Future development will be required to conform to zoning standards and all applicable health and safety codes. E. Would the proposal involve increased fire hazard in areas with flammable brush, grass, or trees? Less Than Significant Impact. The proposed project site is on an alluvial fan with sparse natural vegetation due to disturbance from previous mass grading for the flood control facilities on the project site. The adjacent mountains have only very sparse vegetation. The dead eucalyptus trees along Old Avenue 52 will be removed. Thus, there is a very low fire potential from brush, grass, or trees. 3.10 '% )ISE Regional Environmental Setting Noise levels in the City are created by a variety of sources within and outside the City boundaries. The major sources of noise include vehicles on City streets and Highway 111, and temporary construction noise. The ambient noise levels are dominated by vehicular noise along the highway and major arterial roadways. Local Environmental .Setting The ambient noise level at the project site is dominated by vehicle traffic noise from Washington Street and Avenue 52. Residential areas are considered noise -sensitive land uses, especially during the nighttime hours. The nearest residential use is located adjacent to the east and north of the project site. The State Building Code requires that interior noise level in buildings do not exceed CNEL 45. The General Plan of the City of La Quinta requires that exterior noise levels do not exceed CNEL 60 (Sources: Site Survey). A noise study has been prepared for this project. 09'1 MI A. Would the project result in increases in existing noise levels? Potentially Significant Unless Mitigated. An acoustical study of the project site were conducted in December, 1996, by Gordon Bricken & Associates. The reports state that noise levels are dominated by vehicular traffic on Avenue 52 to the north, and Avenida Bermudas to the west. No other significant sources of noise were noted during the site visit. The report discusses the design of the proposed project and recommends mitigation measures to protect the proposed homes from street noise. Mitigation includes the construction of at least a 6 foot solid wall along the perimeter of the project, and constructing to meet certain criteria to ensure an outdoor -to -indoor noise intrusion of no greater than 45 dBA. These criteria are contained in the acoustical study and shall be made part of the Conditions of Approval and the Mitigation Monitoring Plan for the project (Source: Gordon Bricken & Associates 1996). The height of residential lot pads is subject to sound attenuation along Avenida Bermudas. In order to ensure compliance with the recommendation of the acoustical study, the pad elevations on several lots have been reduced. There is an existing single family house located at 51-485 Calle Guatemala that abuts the project site along the northern property line. This house is constructed either on the lot line or possibly over the lot line. In order to mitigate this issue, the applicant will be required to process a lot line adjustment to provide a five-foot setback for the Calle Guatemala property. The perimeter wall which will be constructed along the entire length of the project's northern boundary would then have a five-foot "jog" in the wall at the Calle Guatemala property. The wall will not only define the project's boundaries, but: will serve to mitigate sound attenuation impacts. B. Would the project result in exposure of people to severe noise levels? Less Than Significant Impact. The La Quinta General Plan regulates excessive noise and vibration in the City by establishing allowable noise levels for various land uses. Residential land uses should have a maximum exterior noise level of up to 60 CNEL. If the ambient noise level is higher than this standard, then it will serve as the standard. The existing CNEL along Washington Street, Avenue 52, and Avenida Bermudas corridors adjacent to the project site is 60+ dBA. The interior of the project site, next to Ave. Bermudas, is between 50 and 60 dBA for that area close to the Coral Reef Mountains is less than 50 dBA (Source: La Quinta MEA). The proposed development will result in short-term impacts associated with construction activities. During construction, heavy machinery will be capable of generating periodic peak noise levels ranging from 70 to 95 dBA at a distance of 50 feet from the source. These high noise levels are short in duration and temporary with the construction phases of the project. Such high noise levels are not anticipated nor permitted after construction, or during the "operation" of the development (Source: La Quinta General Plan). It is possible that blasting may be necessary to grade those areas in the higher fan and slopes to create pads sites and golf tee boxes (Leighton and Associates 1986). However, the 092 36 developer has stated in a letter to the City that blasting will not be used during grading. Blasting will be prohibited for this project. 3.11 PUBLIC SERVICES Regional Environrnental.Setting La w enforcement services are provided to the City through a contract with the Riverside County Sheriff's Department. The Sheriff's Department extends service to the City from existing facilities located in the City of Indio. There is a small substation located within City Hall. The Department utilizes a planning standard of 1.5 deputies per 1,000 population to forecast additional public safety personnel requirements in La Quinta at buildout. Based on this standard, the City should have a police force of 25.5 officers, but is currently underserved. Currently, there are three officers per shift with three staggered shifts per day to serve La Quinta. In addition to patrol, there is also a target team, Community Services Officer, and School Resources Officer assigned to the City (Source: 101-301 Police Services Supporting Information). Fire protection service is provided to the City by Riverside County Fire Department through a contractual arrangement. The Fire Department administers two stations in the City; Station #32 on Frances Hack Lane, west of Washington Street, and Station 470, at the intersection of Madison Street and Avenue 54. The Fire Department is also responsible for building and business inspections, plan review, and construction inspections. Based upon a planning standard of one paid firefighter per 1,000 population, the City is currently underserved (Source: La Quinta MEA). Currently, there are two paid firefighters per shift at each of the two fire stations in La Quinta. Volunteers supplement the paid staff (Source: La Quinta Building & Safety Department). Structural fires and fires from other man-made features are the most significant fire th-eats to the City. Hillside and brush fires are minimal as the hillside areas are virtually barren, and the scattered brush on the valley floor is too sparse to pose a serious fire threat. Both the Desert Sands Unified School District and the Coachella Valley Unified School District serve the City. There is one elementary school, one middle school, and one high school within the City. Another elementary school is under construction within the City. The City is also within the College of the Desert Community College District. Library services are provided by the Riverside County Library System with a branch library located in the Village area of the City. The existing facility opened in 1988 and unadopted planning standards of 0.5 square feet per capita and 1.2 volumes per capita to forecast future facility requirements to serve the City. Utilizing this 1992 standard, the City was underserved in space but overserved in terms of volumes (Source: La Quinta MEA). 37 093 Health care services are provided in the City through JFK Memorial Hospital in Indio, and the Eisenhower Immediate Care Facility in the 111 Center. The Eisenhower Medical Center is located in Rancho Mirage. The Riverside County Health Department administers a variety of health programs for area residents and is located in Indio. Paramedic service is provided to the City by Springs Ambulance Service. Local Environmental Setting The nearest City fire station to the project site is Station #32 located at the northwest corner of the project site. Governmental services in La Quinta are provided by City staff at the Civic Center, and by other County, state, and federal agency offices located in the desert area or region. The project site will be serviced by the local schools. A. Would the project have an effect upon, or result in the need for new or altered governmental services in relation to fire protection? Less Than Significant Impact. The proposed project will increase the need for fire protection due to the construction of residential units, a clubhouse, and other facilities. Development of the project shall comply with the fire flow and fire safety building standards of the Riverside County Fire Code to prevent fire hazard on -site and to minimize the need for fire protection services. Unobstructed fire access will be required through the design of the project streets and setbacks between structures. Other code requirements (such as sprinkler systems, construction materials, etc.) shall be complied with (Source: Fire Department). B. Would the project have an effect upon, or result in the need for new or altered government services in relation to police protection? Potentially Significant Unless Mitigated. Comments have been received by the Sheriff's Department for this project. There will be a cumulative impact upon police protection services by the construction of new residential units that will generate calls for various types of police services and protection. Traffic collisions, patrol requests, and calls for service will impact the Sheriff's Department. This will generate a need for additional staff in the future. C. Would the project have an effect upon, or result in a need for new or altered government services in relation to school services? Potentially Significant Unless Mitigated. A response was received from the Desert Sands Unified School District, dated October 24, 1996. The letter states that the proposed project will potentially result in an impact on their school system. School overcrowding is a District -wide concern for Desert Sands. The District's ability to meet the educational needs of the public with new schools has been seriously impaired in recent years by local, 094 38 state, and federal budget cuts that have had a devastating impact on the financing of new schools. The school mitigation fee that is currently collected on all new development at the time building permits are issued will be required of this project (Source: DSUSD letter of October 24, 1996). D. Would the project have an effect upon, or result in a need for new or altered government services in relation to the maintenance of public facilities, including roads? Potentially Significant Unless Mitigated. The project site is not served by existing, but limited infrastructure connected with the past ranching operation. The proposed project will not require new and altered services for the maintenance of roadways or other facilities, as internal streets will be private. Additional public roads at the entrances to the projects will require maintenance by the City, which may impact current staff and budget concerns. E. Would the project have an effect upon, or result in a need for new or altered government services in relation to other governmental services? Less Than Significant Impact. Building, engineering, inspection, and planning review needed for the proposed project will be partially offset by application, permit and inspection fees charged to the applicant and contractors. 3.12 UTILITIES Regional Environmental .Services The City of La Quinta is served by the Imperial Irrigation District (IID) for electrical power supply and The Gas Company (TGC) for natural gas service. Existing power and gas lines and substations are found throughout the City. IID has four substations in La Quinta, with electricity generated by a steam plant in El Centro and hydroelectric power generated by the All American Canal. General Telephone Exchange (GTE) provides telephone services for the City. Colony Cablevision serves the area for cable television service. The Coachella Valley Water District (CVWD) provides water and sewer service to the City. CVWD obtains its water from underground aquifers and from the Colorado River. CVWD operates a water system with potable water pumped from domestic water wells in the City. The wells range in depth from 500 to 900 feet. Potable water is stored in five reservoirs located in the City. The City's stormwater drainage system is administered by the CVWD, which maintains and operates a comprehensive system to collect and transport flows through the City. The City is served by Waste Management of the Desert for solid waste disposal. 095 9 Nonhazardous, mixed municipal solid waste is taken to three landfills within the Coachella Valley. Local Environrnental.Setting The project is adjacent to developed areas on the west, north, and east. The site is former farm land that has been under cultivation until recent years. A. Would the project result in a need for new systems, or substantial alterations to power and gas service? Potentially Significant Unless Mitigated. Power, sewer, and natural gas lines have been brought in to the community and are available to the project site. It is not anticipated) that the project will require a significant level of electricity or natural gas to result in the need for new systems or alterations to existing systems. The project developer will have to coordinate with IID, CVWD, cable company, and TGC for the timely provision of utilities. A response letter from IID, dated October 28, 1996, was received by the City. The letter states that the proposed project will impact electric service to the area. The cumulative impact of projects of this size do increase the electrical demand on the IID's existing facilities at peak leading periods, and result in the need for additional generation, transmission, substation, and distribution facilities. When additional facilities are needed, projects of this magnitude directly impact power rates in the IID's service area and may result in higher electric rates in the future years (Source: IID letter dated October 28, 1996). B. Would the project result in a need for new systems, or substantial alteration to communication systems? Less Than Significant Impact. The proposed development will require service from General Telephone Exchange (GTE) for telephone communication. The developer will be required to coordinate the installation of telephone service infrastructure with GTE. A fiber optic cable is located along Old Avenue 52. This cable will need to be relocated prior to grading in that area. Relocation is the responsibility of the applicant (Source: Richard Tyree, GTE: Jan. 2, 1997). C. Would the project result in a need for new systems, or substantial alterations to local or regional water treatment or distribution facilities? Less Than Significant Impact. The proposed project will require water service. It i.s not anticipated that the project will result in a significant adverse impact upon the water resources of CVWD, with the construction of new facilities, including wells, reservoirs, and booster pumping stations. The developer will be required to provide land on which some of these facilities will be located. Potable water consumption has been discussed in 096 section 3.4 of this document. A response letter from CVWD has been received that states that the district will furnish domestic water and sanitation service to the project. The project will be required to be annexed into Improvement District No. 55 to obtain sanitation service (Source: CVWD letter dated November 14, 1996). D. Would the project result in a need for new systems, or substantial alterations to sewer services or septic tanks? Less Than Significant Impact. The proposed project will generate sewage which will have to be transported and treated by CVWD. The developer will be responsible for the cost of connection and installation of an on -site sewer system. A response from CVWD has been received. See discussion above in subsection D (Source: CVWD letter dated November 14, 1996). E. Would the project result in a need for new systems, or substantial alteration to storm water drainage? Less Than Significant Impact. The project site is vacant farm land. The project will result in substantial construction of buildings, pavement and landscaping. Additional on - site retention facilities will be required for the development of the project. The Whitewater River Storm channel is located approximately 3 miles south of the project site. There will be no significant impacts to the channel (Source: Site Survey; La Quinta General Plan). F. Would the project result in a need for new systems, or substantial alteration to solid waste disposal? Less Than Significant Impact. The proposed project will require solid waste disposal services from Waste Management of the Desert, the current purveyor of solid waste collection. Solid waste may be transported to the three existing landfills in the Coachella Valley. These landfills are reaching capacity and may be closed in the near future. Development must comply with the City's Source Reduction and Recycling policies. However, other sites or alternative types of waste disposal projects are being considered. Any on -site programs will be coordinated with Waste Management. Solid waste generation is calculated at 4.00 lbs. per person per day (La Quinta General Plan). 3.13 AESTHETICS Regional Environmental Vetting The City of La Quinta is partially located within a desert valley cove. There are hillsides to the west and south of the City. Views of the desert and surrounding mountains are visible on clear days throughout most of the City. 09-7 41 Local Environmental.Vetting The project site is located in a predominately residential zoned area in the southern portion of the City. The Cove residential area immediately to the west, allows a maximum of 17 feet for a single family residence. The proposed project site is in the RL district that allows up to 28 feet in height with the exception for houses along Ave. Bermudas which will be restricted to 17 feet height limitation. Views from the project site consists of the Santa Rosa and Coral Reef Mountains to the south and southeast, the alluvial fan area to the southwest, and the open valley floor to the north and northeast (Source: Site Survey; La Quinta MEA). A. Would the project affect a scenic vista or scenic highway? Less Than Significant Impact. The project site is located within designated viewshed No. 1, which includes both distinctive and attractive types of viewsheds. The vistas from the project site include the Coral Reef Mountains adjacent to the east and south, the Santa Rosa Mountains to the south and west, and the valley floor to the northeast. Less than significant impacts are anticipated by this project as the majority of proposed development will be located on the gently sloping alluvial fan area (Source: La Quinta MEA; Site Survey). The applicant has submitted a viewshed study of the six residential lot area and tee boxes 417, 2, and 18, as required for the Conditional Use Permit. The six lots, are proposed for an alluvial fan within the Coral Reef Mountains. Slopes vary widely within this alluvial fan. The fan was scarred by construction activities by the CVWD, in 1988, when nearby flood control facilities were constructed. There is a distinct color difference created by the scarring. The proposed six lots on this fan will in effect eliminate the scarring through proposed development and restoration of any remaining scarring. B. Would the project have a demonstrable negative aesthetic effect? Less Than Significant Impact. The proposed project will be required to comply with architectural and landscaping policies and ordinances of the City in effect at the time of development. It is possible that the alluvial fan where six residential lots are proposed for approval under Conditional Use Permit 96-031 would have a negative impact upon the local environment as the proposed street to access these lots would result in a 10-foot scar wall in one area where the road is proposed to be constructed over an elevated ridge line. Staff has determined that there is an opportunity to realign the road off the ridge line to a lower area to prevent the scar wall and keep development out of the 20% slope areas. The realignment of this road will be a condition of approval for the Conditional Use Permit:. The six proposed lots under the Conditional Use Permit also have small portions of the lots within the 20% or greater slope areas. Development is not permitted above 20% slope. However, those lots that have small areas at the rear within 20% or greater slopes will be required to have conservation easements recorded on them, with no grading permitted in these areas. The applicant will have to redesign the grading plan for this area to eliminate all grading in areas above 20% slope gradient. The grading on the six lots will be required to avoid flat planes in order to soften the impact of grading. Grading will only be permitted within that area that was previously scarred by CVWD flood control construction activities on the alluvial fan. All areas graded on the alluvial fan are subject to restoration of existing or project -related scarring. The applicant will be conditioned to revise the slope study to include a dashed line indicating the limits of the existing scarred area. Any modifications to the alluvial fan area subject to Conditional Use Permit 96-031 will require a revision to the CUP, subject to the environmental and public hearing process. The 15 foot slope between lots 230, 231, 232, and the lower road will be required to be landscaped to soften the visual impact of the grading. C. Would the project create light or glare? Potentially Significant Unless Mitigated. The proposed project will include exterior security and low level landscaping lighting which will cumulatively contribute to the existing light and glare in the City. All such lighting fixtures shall be required to comply with the Dark Sky Ordinance and other policies of the City, in order to reduce the impact. A lighting plan will be required to be submitted for review and approval for the proposed development. 3.14 CULTURAL RESOURCES Regional Environmental Setting A portion of the prehistory of the La Quinta area is known through the archaeological record gained from various archaeological investigations over the past twenty years and from extensive ethnographic information. A discussion of the prehistory and history of La Quinta is provided in the Draft Mstoric Context Statement of the City of La Quinta. Other discussions are found in the La Quinta General Plan and the Master Environmental Assessment. Local Environmental Setting The project site is located in the southern portion of the City. There are recorded archaeological sites within a one mile radius of the project site as well as sites on the project site. The project site was previously surveyed for archaeological or historical resources, with both archaeological or historical sites recorded on the property. In 1984, the first archaeological investigation took place on the project site in conjunction with a similar proposed golf course/country club project. This Phase I investigation was conducted by UCR ARU. Six archaeological sites were recorded at that time. Local Native American consultation for these sites was included in the analysis and determination of mitigation measures to be required for the sites. 0'T91 43 As mitigation for the archaeological sites for the project under review at that time, an extensive Phase II investigation was conducted in 1989, by UCR ARU, to test several of the sites and determine their perimeters and significance. Eleven human cremations were recovered from site Riv-1179, as well as numerous artifacts. The additional mitigation for this site was determined to be capping in order to preserve the remaining subsurface deposits and to memorialize the burial ground. The six sites found on the project site; are connected with a prehistoric village area, located partially on the property. Over the past years there has been frequent looting of the sites and casual pothunting by people trespassing onto the property. In 1988, the Coachella Valley Water District undertook construction of a large detention basin, drainage channels, and related flood control facilities on the project site. In the Environmental Assessment prepared by CVWD., the archaeological resources were not given consideration (CVWD File No. 0121.3198). At least two of the archaeological sites were destroyed at that time by the water district's actions. There is no record of archaeological monitoring or other mitigation by CVWD at that time. Thus, two of the sites are lost. The remaining sites consist of bedrock milling stations located at the toe of the slope. These site can easily be preserved and incorporated into the project as cultural features, and thus preserved. Riv-1179 was capped by Keith Companies archaeologists Paul G. Chace, Ph.D., and Charles Reeves, J.D., in December 1996. The capping consisted of carefully placing at least three feet of clean, fine sand over the top of the designated site area. The heavy equipment did not touch the site area. The capping was photodocumented. Annual inspections of the capped site will be required by the City staff to ensure the stability and proper maintenance of the capping. The capped site will be required to have a conservation easement placed on it with the deed going to the City in perpetuity. The site will be preserved for the sensitive memorial of the human remains and for future scientific study. A. Would the project disturb paleontological resources? Less Than Significant Impact. It is known that marine -associated paleontological resources are found at elevations below 42 feet above mean sea level. The proposed project site is located at elevations ranging between 42 and 1600 feet above MSL. Thus, it was determined that the project site was just outside of the area designated by the Lakebed Paleontological Determination Study. The project site will have archaeological monitoring of the earth -moving activities, which will provide for a contingency in the event that paleontological resources are uncovered as well (Source: Lakebed Paleontological Determination Study; Wilke 1984; UCR ARU 1986). B. Would the project affect archaeological resources? Less Than Significant Impact. There are numerous archaeological sites within close proximity of the proposed project. The archaeological survey conducted on the project site did locate and record six prehistoric archaeological sites. A discussion of these sites and their current status is provided above. Because of the potential for subsurface cultural 100 44 deposits, it is recommended that archaeological monitoring during the clearing and grubbing, grading and trenching of the project should be done for all on -site and project - related off -site work (Source: Wilke 1984; UCR ARU 1986). C. Would the project affect- historical resources? Potential Impact Unless Mitigated. There are historical resources located and documented on the project site. The resources consist of the Hacienda Del Gato and related buildings. In addition there are fixtures related to the ranching operation of the property that are of historic age and significance. The property was purchased frorn the state by John and Belle Marshal in 1902. They established a date and citrus ranch and constructed a large hacienda -style home in the 1930's. The first structure on the ranch were a small adobe house, equipment barn, and later a caretakers house. The ranch is discussed in the City's Draft Historic Context Statement and documented in a focused historic investigation by Mellon and Associates, in November 1996. It has 'been determined that the hacienda and adjacent grounds are significant historic resources to the community and that every effort to preserve, rehabilitate and adapt the property is to be made. A Certificate of Appropriateness was applied for by the applicant to seek approval of various treatments to the hacienda, and the surrounding grounds, from the City. The proposed treatments are independent from the project in that they can stand alone even if the project is never constructed, and that they further the goal of preservation of an important historic resource. Certificate of Appropriateness 96-001 was recommended for City Council approval by the Historic Preservation Commission on January 16, 1997. (Sources: La Quinta Historical Society; La Quinta General Plan; La Quinta MEA, Mellon and Associates 1996). In December 1996, The Keith Companies documented Old Avenue 52,which had been identified by staff as a potential historic road. The Historic Preservation Commission concluded that the road was significant as a historic resource, however, due to the loss of the road's integrity. this resource does not warrant preservation or additional mitigation beyond the documentation prepared by the consultant. D. Would the project have the potential to cause a physical change which would affect unique ethnic values? No Impact. There is no identifiable unique ethnic value to the proposed project site. The project site has been a ranch that was first established in 1902. However, development of the property has been anticipated and promoted since the early 1980's. The historic house and grounds will be preserved and incorporated into the proposed development. There are no unique ethnic values identified with the property, other than local historic and prehistoric significance. E. Would the project restrict existing religious or sacred uses within the potential impact area? No Impact. There are no known current religious uses or sacred uses on the proposed project site. The archaeological investigation for the project transmitted letters of inquiry 45 to the local tribal councils requesting their comment of this and other issues. No responses were received. 3.15 RECREATION Regional Environmental.Setting The City of La Quinta has an adopted Parks and Recreation Master Plan that assesses the existing resources and facilities and the future needs of the City. The City has approximately 28.7 acres of developed parkland for Quimby Act purposes. The 845 acre regional ]Lake Cahuilla Park is not included in this count. There are also unimproved bike and equestrian corridors within the City and designated pedestrian hiking trails. Local Environmental &tting The project site is former farm land with an historic house and out -buildings. There is no evidence that there have been any organized or approved recreational uses on the property. The proposed project includes an 18-hole golf course that will provide recreation to the country club members. A. Would the project increase the demand for neighborhood or regional parks or other recreational facilities? Potentially Significant Unless Mitigated. The proposed project will impact the existing park and recreation facilities by the construction of 241 new residential lots. Park fees in lieu of parkland dedication will be required for this project in order to mitigate this impact upon local parks. The Parks and Recreation Master Plan states that Planning Area C, within which the project site is located, is significantly deficient in park and recreation facilities. The paying of the parkland fee will assist in acquiring the necessary funds to develop future parks and other recreation facilities in Planning Area C (Sources: Parks and Recreation Master Plan). B. Would the project affect existing recreational opportunities? Potentially Significant Unless Mitigated. The proposed project of 241 residential lots will affect existing parks and recreation facilities through added users. There is a significant deficit in existing parks in the northern area of the City. However, the Fritz B. Burns Park is located at the northwest corner of the project site. Added users would result in an increased demand upon the existing park facilities and recreational programs. Payment of the parkland fee will mitigate this impact by contributing funds toward the construction of new park facilities and added recreational programs. SECTION 4: MANDATORY FINDINGS OF SIGNIFICANCE The proposed project will not have unmitigable significant adverse impacts on the environmental issues addressed in the checklist and addendum. Some of the issue areas could have a potential significant impact if appropriate mitigation measures are not implemented. The following findings can be made regarding the mandatory findings of significance set forth in Section 15065 of the CEQA Guidelines and based on the results of this environmental assessment: * The proposed project will not have the potential to degrade the quality of the environment, with the implementation of mitigation measures. * The proposed project will not have the potential to achieve short term goals to the disadvantage of long-term goals, with the successful implementation of mitigation. * The proposed project will not have impacts which are individually limited but cumulatively considerable when considering planned for proposed development in the immediate vicinity. * The proposed project will not have environmental effects that will adversely affect human, either directly or indirectly, with the implementation of mitigation. SECTION 5: EARLIER ANALYSES A. Earlier Analyses Used. In 1992, EA 92-240 was prepared for Tentative Tract Map 27613. The current proposed project site is the same location encompassed by Tentative Tract 27613. EA 92-240 assessed the potential impacts to the environment from the project proposed at that time. That project consisted of 399 residential units and an 18-hole golf course, and was known as The Traditions. Much of the general environmental information on resources and hazards assessed in 1992 is still valid for the current proposed project. A Mitigated Negative Declaration of Environmental Impact was certified for that assessment. Also utilized in the current analysis was the La Quinta Master Environmental Assessment (MEA), prepared in 1991, in conjunction with the 1992 General Plan Update and related EIR.

Speed 45 MPH - too fast ( only 50% of traffic obey this �� 1 �� 2 9 7 limit) 2.Very hard to get out of driveway ., 3.If anyone comes over to visit -its very dangerous to get in and out of car when they have to park in street in front of homes 4.Many new homes in cove -more traffic S.Children in cove walk on west side of Bermudas -there are no homes on the east side where there is a side walk,and no cross walks to cross the freeway like Bermudas to get over to sidewalk. 6.No frontage to homes on Bermudas -for a four lane street 7.The TRADITION will bring much more traffic to Bermudas and if they build on the top of the cove what then? EISENHOWER- old main flow for traffic in and out of cove 1.Has sidewalks on both sides of street 2.Has crosswalks 3.Has center divider -with landscaping and lighting and turn outs 4.Homes have larger frontage set back to allow for larger street and sidewalks and heavy traffic 5.Eisenhower will not come close to the traffic Bermudas gets with TRADITION and the maybe project on the top of the cove, along with all the new homes in the cove. NOW IS THE TIME TO MAKE AVE BERMUDAS A SAFE STREET, AND TO GIVE IT A LITTLE BEAUTIFICATION BEFORE IT IS IMPOSSIBLE. THE WALL TO BE INSTALLED BETWEEN BERMUDAS AND TRADITION. PLEASE DONT LET THEM BUILD IT SO IT LOOKS LIKE THE COVE IS IN A PRISON- TAKE A LOOK AT BIG HORN -THERE WALL IS BUILT SO ITS PRIVATE BUT STILL KEEPS THE BEAUTY OF THE AREA,WE WOULD LIKE TO BE ABLE TO STILL LOOK OUT AND SEE THE DESERT BEAUTY OF THE HILLS.
