PCRES 1999-027PLANNING COMMISSION RESOLUTION 99-027 A RESOLUTION OF THE PLANNING COMMISSION OF THE CITY OF LA QUINTA, CALIFORNIA, CERTIFYING A MITIGATED NEGATIVE DECLARATION OF ENVIRONMENTAL IMPACT FOR ENVIRONMENTAL ASSESSMENT 99-377 PREPARED FOR CONDITIONAL USE PERMIT 99-043 TO ALLOW A CELLULAR TELEPHONE ANTENNA SITE TO BE INSTALLED ON THE ROOF OF AN EXISTING BUILDING AND SCREENED WITH A 5.5-FOOT TALL STUCCO PARAPET WALL, WITH ASSOCIATED EQUIPMENT HOUSED WITHIN THE EXISTING BUILDING LOCATED WITHIN THE VILLAGE COMMERCIAL (VC) ZONING DISTRICT AT 78-080 CALLE ESTADO. ENVIRONMENTAL ASSESSMENT 99-377 APPLICANT: AIRTOUCH CELLULAR WHEREAS, the Planning Commission of the City of La Quinta, California, did on the 13"' day of April, 1999, hold a duty noticed Public Hearing, at the request of AirTouch Cellular, to allow a cellular telephone antenna site at 78-080 Calle Estado; 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, and has determined that although there is some potential for the proposed cellular telephone antenna site to have potentially significant adverse impacts, there would not be a significant effect in this case because appropriate mitigation measures were made a part of the assessment and are included in the Conditions of Approval, and a Mitigated 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 certifying said Environmental Assessment: The proposed cellular telephone antenna site will not be detrimental to the health, safety, or general welfare of the community, either indirectly or directly, in that no significant unmitigated impacts have been identified by Environmental Assessment 99-377. 2. The proposed cellular telephone antenna site does not have the potential to degrade the quality of the environment, substantially reduce the habitat of a fish or wildlife population to result in a drop below self sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of rare or endangered plants or animals, or eliminate important examples of the major periods of California history or prehistory, due to the lack of any such resources existing on or near the existing project site. Planning Commission Resolution 99-027 Conditional Use Permit 99-043 April 13, 1999 3. The proposed cellular telephone antenna site does not have the potential to achieve short-term environmental goals, to the disadvantage of long-term environmental goals, as no significant effects on environmental factors have been identified by Environmental Assessment 99-377. 4. The proposed cellular telephone antenna site will not result in impacts which are individually limited or cumulatively considerable when considering planned or proposed development in the immediate vicinity, as the area is an established commercial district with infrastructure in place to support the requested antenna site, and the proposal is considered an ancillary part of the existing use which will not effect an increase in growth through any modification of the current conditions on the site. 5. The proposed cellular telephone antenna site will not have environmental effects that will adversely affect the human population, either directly or indirectly, as supporting documentation submitted by the applicant indicates that microwave and cellular telephone antenna emissions associated with the proposal will be substantially below nationally recognized safety thresholds. NOW, THEREFORE, BE IT RESOLVED by the Planning Commission of the City of La Quinta, California as follows: That the recitations are true and correct and constitute the findings of the Planning Commission for this Environmental Assessment. 2. That it does hereby certify Environmental Assessment 99-377 for the reasons set forth in this Resolution and as stated in the Environmental Assessment Checklist and Addendum on file in the Community Development Department. PASSED, APPROVED, AND ADOPTED at a regular meeting of the La Quinta Planning Commission held on this 130' day of April, 1999, by the following vote, to wit: AYES: Commissioners Abels, Butler, Robbins, and Chairman Tyler.

P:\EA99-377AirTouch.wpd - -1- Environmental Factors Potentially Affected: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages_ Aesthetics Hazards and Hazardous Public Services Materials Agriculture Resources Hydrology and Water Quality Recreation Air Quality Land Use Planning Transportation/Traffic Biological Resources Mineral Resources Utilities and Service Systems Cultural Resources Noise Mandatory Findings Geology and Soils Population and Housing Determination (To be completed by the Lead Agency.) On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the applicant. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a "potentially significant impact' or "potentially significant unless mitigated" on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze ortly the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EK including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. 11 ✓) ll� ✓cog L q -qG ig ature Date �, sl 1'gf,%}'1 ©"rI'ta (land GLfu ref 4_ u lr teF — Printed Name For C,000v8 -2- Evaluation of Environmental Impacts: 1) A brief explanation is required for all answers except "No Impact' answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact' answer is adequately supported if the reference information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone). A "No Impact' answer should be explained where it is based on project -specific factors as well as general standards.(e.g. the project will not expose sensitive receptors to pollutants, based on a project -specific screening analysis). 2) All answers must take account of the whole action involved, including off -site as well as on - site, cumulative as well as project -level, indirect as well as direct, and construction as well as operational impacts. 3) "Potentially Significant Impact' is appropriate if there is substantial evidence that an effect is significant. If there are one or more "Potentially Significant Impact' entries when the determination is made, an EIR is required. 4) "Negative Declaration: Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact' to a "Less Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVIII, "Earlier Analysis," may be cross-referenced). 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063(c)(3)(D). Earlier analyses are discussed in Section XVIII at the end of the checklist. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g., general plans, zoning ordinances). Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8) The analysis of each issue should identify: a) the significance criteria or threshold used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the impact to less than significance PAEA99-377AirTouchmpd -3- Sample question: Issues (and Supporting Information Sources): Would the proposal result in potential impacts involving Landslides or mudslides? (1,6) (Attached source list explains that 1 is the general plan, and 6 is a USGS topo map. This answer would probably not need further explanation.) L AESTHETICS.

This will increase the height of the existing parapet roof from 31.5 to 37 feet at the north west corner of the building. The wall will be equal in height with the tallest point on the building. The proposed wall addition will result in additional mass for the rear of the existing building, with its four -walled square shape. The rear of the building is visible to the alley -way. Future development north of the building should block the view of the rear elevation where the new parapet wall is proposed. To break-up the proposed expanse of wall area, the applicant has proposed decorative design elements (i.e. quatrefoils - coping to complement the design of the building). There are existing mature trees planted along the rear of the building. Mitigation for this issue is by the proposed decorative elements for design compatibility. VI. a-ii) The City is located in s seismically active area. The proposed Conditional Use Permit is located in a Zone III groundshaking zone. The City has implemented provisions in the Uniform Building Code for seismically active areas. The proposed project will be required to conform to these standards. This mitigation measure will ensure that impact from seismic activity will be reduced to a level of insignificance. XII. a) The addition of the proposed cellular antenna site will increase and/or improve the existing cellular telephone service to the Cove area of La Quinta. This increased service could indirectly encourage population growth by providing cellular service to areas previously without such service, or improve existing service. Potential growth is not anticipated to be substantial, thus any adverse impact resulting from the proposed project will not be significant, and not warrant mitigation.
