OF THE CITY OF LA QUINTA, CALIFORNIA,
RECOMMENDING TO THE CITY COUNCIL
APPROVAL OF A TIME EXTENSION AND TRACT
AMENDMENT FOR TT 29323, TO DIVIDE 117
ACRES INTO 349 SINGLE FAMILY LOTS
CASE NO.: TENTATIVE TRACT MAP 29323
APPLICANT: CORNERSTONE DEVELOPMENT
WHEREAS, the Planning Commission of the City of La Quinta, California,
did on the 11 th day of June, 2002, hold a duly noticed Public Hearing at the request
of Cornerstone Development to subdivide 117 acres into 349 single family residential
lots and several lettered lots, generally located on the northwest corner of Fred Waring
Drive and Jefferson Street, more particularly described as:
Portion of the SE 1/4 of Section 17, T5S, R7E, S.B.B.M.
WHEREAS, at said public hearing, upon hearing and considering all
testimony and arguments, if any, of all interested persons wanting to be heard, said
Planning Commission did make the following mandatory findings to approve said time
extension and tract amendment for Tentative Tract Map 29323:
Finding Number 1 - Consistency with CEQA
The La Quinta Community Development Department has prepared
Environmental Assessment 2002-446, an addendum to Environmental
Assessment 99-389 for TT 29323, which was certified on February 15, 2000.
Based on this addendum, the Community Development Department has
determined that none of the circumstances or conditions which would trigger
the preparation of a subsequent Environmental Impact Report pursuant to Public
Resources Code Section 21166, have been shown to exist.
Finding Number 2 - Consistency with the General Plan
The proposed Tentative Tract Map amendment is consistent with the City's
General Plan with the implementation of Conditions of Approval to provide for
adequate stormwater drainage, and other infrastructure improvements. The
project is consistent with the Low Density Residential land use designation of
Up to 4 dwelling units per acre, as set forth in the General Plan.

Tentative Tract 29323, Extension Al Amendment #1
Cornerstone Development
June 11, 2002
Finding Number -a - Consistency of Design and Improvements
The design and improvements of the proposed subdivision 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.
Finding Number 4 - Consistency of Public Easements
As conditioned, the design of the subdivision and type of improvements,
acquired for access through, or use of, property within the proposed subdivision
will not conflict with such easements.
Finding Number 5 - Public Health and Safety
The design of the subdivision and type of improvements are not likely to cause
serious public health problems, in that this issue was considered in
Environmental Assessment 99-389 and Subsequent Environmental Assessment
2002-446, in which no significant health or safety impacts were identified for
the proposed Revised Project.
Finding Number 6 - Suitability of Site
The site of the proposed subdivision 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.
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 constitute the findings of the Planning
Commission in this case;
2. That it does hereby require compliance with those mitigation measures required
for Tentative Tract Map 29323;
3. That it does recommend approval of Tentative Tract Map 29323, Extension #1
Amended, to the City Council for the reasons set forth in this Resolution and
subject to the attached conditions.
