BACKGROUND During 2002, the Governor signed into law Senate Bill (SB) 610 designed to achieve greater coordination during the land use planning process between local water supply agencies and local land use agencies when considering certain large-scale development projects. SB 610 added new provisions to the California Environmental Quality Act (CEQA) and the State Water Code and requires a Water Supply Assessment (WSA) to be prepared for certain large scale development projects. The total, cumulative water demands for the Stoneridge Drive Specific Plan Amendment and related proposed PUD development plan proposals (collectively, "the Project"), trigger the provisions of SB 610. The WSA must be approved by the City Council as the governing body of the City's Public Works Department, which is the public water supplier that would serve the Project. Approval of a WSA is not approval of the Project itself for which the WSA is prepared. Rather, a WSA is an informational document required to be prepared for use in the City's environmental review of a project under CEQA. It assesses the adequacy of water supplies to serve the proposed project and cumulative demand. The content of a WSA is specified by the Water Code and includes identification of any existing water supply entitlements or contracts, and detailed information about groundwater supplies. If the project was included as part of the projected water demand accounted for in the most recently adopted Urban Water Management Plan (UWMP), the water supplier may incorporate information from the UWMP in preparing the WSA. In this instance, the City's existing UWMP did account for water uses within the Project area, but with different water use factors. An updated UWMP, which does account for the proposed water demands of the various uses within the Project, is currently in preparation, but has not yet been approved. Nonetheless, this WSA incorporates the updated water use demands for the Project's various land uses and concludes that: • The City has adequate water supplies through agreements with the Zone 7 Water Agency (Zone 7) and using the City's own groundwater well supplies to meet the Project's near-term and cumulative, long-term water demands through 2030. • Zone 7 has adequate treatment, conveyance and groundwater pumping facilities to serve the Project's water demands. In addition, additional treatment, conveyance and groundwater pumping projects to further enhance Zone 7's local water treatment, pumping and conveyance system are either in final design (with funds to construct these facilities already budgeted) or are currently being constructed. Based upon these conclusions, staff recommends that Council approve the attached resolution adopting the subject WSA. A copy of the WSA for the proposed Project is attached to the resolution.
