AGENDA 71TLE: Adopt Separate Resolutions Approving Water Supply Assessment Reports
for Reynolds Rand Project and Westside -Southwest Gateway Project
MEETING DATE: July 19, 2006
PREPARED BY: Public Works Director
RECORWENIDED ACTION: That the City Council adopt separate resolutions approving Water
Supply Assessment reports for the Reynolds Ranch project and
Westside -Southwest Gateway project.
BACKGROUND INFORMATION: The Water Supply Assessments for the Reynolds Ranch (Exhibit A)
and Westside -Southwest Gateway (Exhibit B) projects were
prepared by Public Works Department staff and Willdan
Consultants, in accordance with Senate Bill (SB) 610 and Water
Code Section 10912. The assessments are in the format designated in State guidelines and document
that sufficient water supply is available to serve the projects. (See summary table, next page.) No
entitlements are conferred upon these projects by the requested action. Approval of the assessment for
each project by the water supplier is a prerequisite to Certification of the Final Environmental Impact
Reports.
The Reynolds Ranch project site is located south of Harney Lane, west of State Highway 99, and east of
the Union Pacific Railroad, as represented in Exhibit C. The Reynolds Ranch project is 220 acres in size,
and the land uses include 20 acres of offices, 40 acres of retail commercial sites, 1,084 residential units
(mix of low, medium, and high density), parks, elementary school and other uses. The annual water
supply required to serve the demands of the project at completion is approximately 501 acre-feet per
year.
The Westside -Southwest Gateway project site is located westerly of Lower Sacramento Road extending
to the General Plan boundary, as represented in Exhibit D. The project is approximately 410 acres in
size, and the land uses include 2,090 residential units, elementary school, parks and other uses. The
annual water supply required to serve the demands of the project is approximately 887 acre-feet per
year.
The data presented in the assessments confirm that water supplies are sufficient during normal,
single -dry and multiple -dry years over a 20 -year planning horizon to serve the demands of existing
development, planned future development within the General Plan, and these proposed projects. A
summary of this data is presented below.
However, additional future development beyond the current General Plan is expected, and as presented
in the 2005 Urban Water Management Plan, demands are expected to exceed supplies by around 2025.
The City will need to secure additional water supplies to serve development beyond 2025. Potential
future water sources include WID, MORE project (Mokelumne River), recharge using captured storm
water runoff, and banked groundwater. A complete master water supply plan will be contained in the
new General Plan.

" Increase in safe yield of the groundwater resource underlying the project area, calculated as the
product of 1.7 acre-feet per year per acre times the acreage of the project.
Although an implementation plan for the use of the WID surface water has not been decided
upon, credit for the supply is permitted by the WSA Guidelines.
d Projected reduction of 15% of existing water demand through meter installation and other
conservation measures. This does not apply to new construction because the effects of metered
water and conservation measures are accounted for in the calculation of water demands.
Remaining vacant land based on current General Plan.
The following actions by the City Council are recommended:
Action A: Adopt resolution approving the Water Supply Assessment for Reynolds Ranch project.
Action B. Adopt resolution approving the Water Supply Assessment for Westside -Southwest
Gateway project.
FISCAL WPACT: None.
