Tentative Tract Map 38083 is consistent with the La Quinta General Plan, and Specific Plan 2004-074, as amended. The Tract Map is consistent with the Low Density land use designation as set forth in the General Plan, and as set forth in Specific Plan 2004-074. 2. The design and improvement of Tentative Tract Map 38083 is consistent with the La Quinta General Plan, and Specific Plan 2004- 074 with the implementation of recommended conditions of approval to ensure consistency for the homes proposed on the lots created herein. The project density is consistent with the La Quinta General Plan and Specific Plan 2004-074 and is comparable to surrounding residential development. The project is consistent with Government Code section 65863, commonly referred to as the “no Net Loss” requirement and with the Housing Criss Act of 2019, Government Code Section 66300. The additional lots meet density requirements and the policies of these sections. 3. The design of Tentative Tract Map 38083 and proposed improvements are not likely to cause substantial environmental damage, nor substantially injure fish or wildlife or their habitat. The City Council, on April 17, 2007, adopted a Mitigated Negative Declaration (MND), Environmental Assessment 2006-577, for the Griffin Ranch Specific Plan and Tentative Tract 32879 project via Resolution 2007-035, in compliance with the requirements of the California Environmental Quality Act (CEQA). The Design and Development Department prepared an addendum to the adopted MND as EA2021-0002, pursuant to Section 15164 of CEQA, in that the project is substantially the same as the previously approved project, that conditions have not substantially changed, and that the findings and mitigation measures contained in EA 2006-577 shall apply to this project. 4. The design of Tentative Tract Map 38083 and type of improvements are not likely to cause serious public health problems, insofar as the project will be required to comply with all laws, standards and requirements associated with sanitary sewer collection, water quality and other public health issues. Planning Commission Resolution 2022-014 Tentative Tract Map 2021-0001 (TTM 38083) Project: Griffin Ranch Adopted: May 24, 2022 Page 3 of 4 5. The design and improvements required for Tentative Tract Map 38083 will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision. All roadway improvements, easements, if any and surrounding improvements will be completed to City standards. 6. The proposed project is consistent with the landscaping standards and plant palette and implements the standards for landscaping and aesthetics established in the General Plan and Specific Plan.
