Quinta, California, did on the 17th day of August, 2004, hold a duly -noticed Public Hearing to consider a request of Tahiti Partners V, to subdivide t 5.0 acres into 19 single-family residential lots and several lettered lots, located on the south side of Darby Road, t 1 /4 mile east of corner of Washington Street, more particularly described as: LOT 24 AS RECORDED IN BOOK 15, PAGE 32 OF RECORDS OF SURVEYS WHEREAS, the Planning Commission of the City of La Quinta, California, did on the 27th day of July, 2004, hold a duly noticed Public Hearing to consider a recommendation on Tentative Tract 31087; and WHEREAS, the Planning Commission of the City of La Quinta, California, adopted Resolution 2004-055, recommending approval of Tentative Tract 31087; and WHEREAS, said legally described property is within an area which is part of the approved Sphere of Influence for the City of La Quinta; and, WHEREAS, California Government Code Section 66454 provides that a City may take action on a tentative subdivision map of unincorporated property adjacent to that City, provided that any approval of said map shall be conditioned upon annexation of said property to such City; and, WHEREAS, the La Quinta Community Development Department has prepared Environmental Assessment 2003-480, and determined that, although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because mitigation measures incorporated into the project approval will mitigate or reduce any potential impacts to a level of non -significance; and, Resolution No. 2004-097 Tentative Tract 31087 Tahiti Partners V Adopted: August 17, 2004 Page 2 WHEREAS, at said public hearing, upon hearing and considering all testimony and arguments, if any, of interested persons wanting to be heard, said City Council did make the following findings to justify approval of Tentative Tract 31087: 1. The proposed Tentative Tract Map 31087 is consistent with the City's General Plan with the implementation of Conditions of Approval to provide for adequate storm water drainage, and other infrastructure improvements. The project is consistent with the adopted Low Density Residential land use designation of up to four dwelling units per acre, as set forth in the General Plan. 2. The design and improvements of the proposed Tentative Tract Map 31087 are consistent with the City's General Plan, with the implementation of recommended Conditions of Approval to ensure proper street widths, perimeter walls, parking requirements, and timing of their construction. 3. As conditioned, the design of Tentative Tract 31087 and type of improvements, acquired for access through, or use of, property within the proposed subdivision will not conflict with such easements. 4. The design of Tentative Tract 31087 and type of improvements are not likely to cause serious public health problems, in that this issue was considered in Environmental Assessment 2003-480, in which no significant health or safety impacts were identified for the proposed project. 5. The site for Tentative Tract 31087 is physically suitable for the proposal as natural slopes do not exceed 20%, and there are no identified geological constraints on the property that would prevent development pursuant to the geotechnical study prepared for the subdivision. 6. The proposed site for Tentative Tract 31087 is within an approved Sphere of Influence for the City of La Quinta and is adjacent to the City corporate limits. Pursuant to California Government Code Section 66454, the City Council may act to approve a tentative map of unincorporated property which meets the aforementioned criteria, provided that such approval is conditioned upon annexation of said property within a specified time period. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of La Quinta, California, as follows: Resolution No. 2004-097 Tentative Tract 31087 Tahiti Partners V Adopted: August 17, 2004 Page 3 1.
