Water-demand projects (as defined in Section 15155 of the State CEQA Guidelines) that require service from a public water system shall prepare a water supply assessment prior to project approval. If the projected water demand associated with the project was not accounted for in the most recently adopted urban water management plan, or the public water system has no urban water management plan, the water supply assessment must address the public water system’s total projected water supplies available during normal, single-dry, and multiple-dry water years for a 20-year projection. The assessment shall describe if the new water service will be sufficiently met under this 20- year projection. The water supply assessment shall be prepared to the satisfaction of and approved by the governing body of the affected public water system and the County. A water-demand project that includes a new water service from a public water system shall not be approved unless adequate water supplies are demonstrated.
