Court finds water supply analysis to be defective
Project was at subdivision map stage, and thus was subject to
Senate Bill 221 requirements, including showing of “firm assurances of future water supplies” (see Gov. Code § 66473.7)
Project also required Water Supply Assessment (WSA) under
Senate Bill 610 (see Wat. Code § 10910 et seq.)
But “ultimate question” was whether EIR adequately addresses
the reasonably foreseeable impacts of supplying water to the project
Vineyard Area Citizens case (2007) requires analysis of
potential water supply alternatives where “the uncertainties inherent in long-term land use and water planning make it impossible to confidently identify the future water sources”

Project site was within Padre Dam Municipal Water District
(PDWD)
- PWD gets its water from San Diego County Water Authority
(SDCWA)
- SDCWA gets most of its water from Metropolitan Water District
(MWD)
- MWD gets its water primarily from State Water Project (SWP)
and Colorado River Aqueduct
WSA estimated water demand at 881 acre feet per year
(afy)
EIR estimated water demand at 1,446 afy
PRESERVE WILD SANTEE (CONT.)
EIR did not adequately explain conclusion that water supply
impacts would be less than significant
- EIR nowhere explained the discrepancy between the EIR water
demand number (1,448 afy) and the WSA number (881 afy)
‒ City argued that discrepancy resulted from EIR’s use of more general categorical
water demand numbers, while WSA used more precise project specific demand numbers
‒ This justification is offered for first time in court briefs, and cannot excuse absence
‒ Even if this is City’s justification is correct, court still has no basis for assuming the
WSA numbers are more accurate than EIR numbers
‒ Although Mayor, at public hearing on project, estimated water demand to be 900 afy,
nothing in record showed that he or other Council members knew of discrepancy between that number and EIR number
- WSA addresses only about 61 % of water demand stated in EIR
