Dear Mr. Rodgers:
Subject: Water Supply Assessment/Water Supply Verification, Travertine Specific Plan Project
The subject Water Supply Assessment and Water Supply Verification (WSA/WSV) for the
Travertine Specific Plan Project (Project) provided an assessment of the Project's anticipated water
demand and verification of the availability of sufficient water supplies during nonnal, single -dry,
and multiple -dry years over a 20 -year projection, considering existing and planned future water
demands of the Coachella Valley Water District (CVWD). The CVWD Board of Directors
approved this WSA/WSV in its regular meeting of November 22, 2006, and an update on March
13, 2018.
TRG Land Inc. submitted a letter dated June 16, 2021, which detailed a proposed amendment to
the Project, provided water demand estimates for the Project with the proposed amendment, and
requested that the 2018 WSA/WSV remain valid given that the amended Project will reduce water
supply needed from the previously approved assessment of 2018 (2018 WSA/WSV, Table 10).
According to the June 16 letter (attached) and the associated water demand estimates provided
therein, the Project reduced the area of disturbance and the amendment will reduce the land use of
the commercial elements of the Project (indoor uses and irrigated outdoor uses) from 7,759,391
square feet to 1,087,355 square feet. The 2018 WSA/WSV estimated a total Project water demand
of 1,225.13 acre-feet per year (AFY). The June 16 letter included an updated estimate of the water
demand for the Project with the proposed amendment of 867.47 AFY. Based on the estimates
provided, the proposed amendment will reduce the Project's water demand by approximately
357.66 AFY.
CVWD staff has reviewed the 2018 WSA/WSV and the provided water demand estimates, and
determined that the Project's overall water demand is decreasing. Sufficient water supplies exist,
or will exist based on current water planning assumptions, to meet the projected demands of the
Project. Based on this review and assessment, an update of the approved WSA/WSV is not
required and the 2018 WSA/WSV is hereby extended through June 24, 2026.

The WSA/WSV will be reviewed every five years, or in the event that water planning assumptions
have changed, until the Project completes construction to ensure it remains accurate and no
significant changes to either the Project or available water supplies have occurred. The Project
applicant shall notify CVWD when construction begins. If neither the Project applicant nor the
lead agency contact CVWD within five years of this extension of the WSA/WSV, CVWD will
assume that the Project no longer exists and the WSA/WSV will become invalid.
Approval of the WSA/WSV does not constitute an approval of the Project or relieve the Project
from complying with all applicable existing and future state, county, city, and local ordinances or
regulations including, but not limited to, the City of La Quinta and CVWD landscape ordinances,
and indoor water use performance standards provided in the California Water Code.
Sincerely,
Steve Bigley

Travertine Water Supply Assessment
Dear Melanie,
This letter is to explain the changes that have been made to the Travertine project since the approval of
the Water Supply Assessment in 2018 and to request that this report will serve to retain that approval.
The project includes basically the same project components; however, the area of disturbance has been
reduced. The number of proposed residential units remains the same, 442 Medium Density Units and 758
Single Family Units with a maximum of 1,200 units.
The tourist commercial elements have been updated in the following manner:

the previously approved assessment of 2018.
