The City is seeking a qualified Consultant to prepare a Water Supply Assessment (WSA) for a proposed Industrial Facility pursuant to the standards set forth in California Water Code (CWC) Section 10910 et seq. (SB 610). The proposed project will be overseen by City staff from the Public Works & Utilities Department and will include staff from Water Resources and Utilities Operations and Maintenance.

The City of Hayward, California, is in Alameda County and is known as the “Heart of the Bay” because of its central and convenient location to San Francisco, Oakland, and San Jose. It is served by an extensive network of freeways and bus lines and has two BART stations and an Amtrak station. Currently, it is estimated that there are approximately 160,000 residents in the City.

Since 1962, the City’s sole source of potable water has been supplied from the San Francisco Public Utilities Commission’s (SFPUC) Regional Water System. The City is a member agency of the Bay Area Water Supply and Conservation Agency (BAWSCA), a special district, comprised of twenty-six member agencies that purchase wholesale water from the SFPUC. BAWSCA represents the interests of SFPUC wholesale water customers by coordinating and providing regional water supply planning, resource development, and water conservation program services to the wholesale purchasers of water from the SFPUC’s Regional Water System.

The City’s water system provides water services for residential, commercial, industrial, institutional and fire suppression purposes. The City owns and operates a municipal wastewater collection system and Water Resource Recovery Facility (WRRF) that serves most of the City, as well as a small number of properties in unincorporated areas of Alameda County. The City is a founding member of the East Bay Dischargers Authority, a Joint Powers Authority that disposes treated wastewater through a deepwater outfall to the San Francisco Bay. The City also owns and operates a recycled water treatment facility that produces disinfected tertiary recycled water for irrigation purposes.

In October 2001, Senate Bill 610 (SB 610) was signed into California state law with an effective date of January 1, 2002. SB 610 (CWC Section 10910 et seq.) amended existing law to require assessment of water supply sufficiency for certain development projects, as defined in CWC Section 10912. SB 610 requires that WSAs be prepared in accordance with the bill’s requirements to recognize that water supply and demand analysis are critical at the early stages of land use planning projects. The basic premise of SB 610 is to determine whether “total projected water supplies available during normal, single dry, and multiple dry water years during a 20-year projection will meet the projected water demand associated with the proposed project, in addition to the public water system’s existing and planned future uses, including agricultural and manufacturing uses,” as described in CWC Section 10910, Paragraph c.3. The legislation encourages agencies to build on information contained in their Urban Water Management Plans (UWMPs) regarding water demand and supply projections. The UWMP is a basic planning tool to document current and future water use, describes water supplies that will be available to meet demand, in both normal and dry years, and to verify adequate supplies will be available to meet demand over a 20-year planning period.

Generally, water supply assessments under SB 610 are triggered by a city or county determination that a particular project is subject to the California Environmental Quality Act (CEQA), Public Resources Code Section 21000, et seq., and that the project falls within the categories set forth in CWC Section 10912. The City has determined that, due to the amount and types of chemicals the project will possess in its inventory at full build-out, the project is subject to approval of an Administrative Use Permit pursuant to Hayward Municipal Code Section 10-1.3100, et seq. As an Administrative Use Permit is a discretionary approval, the City has determined that the project is subject to review under CEQA. Further, because the project will demand an amount of water equivalent to, or greater than, the amount of water required by a 500 dwelling unit project, the project requires a WSA.
