On June 3, 1998, the District and City of Laguna Beach filed an application with the Local Agency Formation Commission (LAFCO) of Orange County California for the District to operate as a subsidiary district of the city while continuing to exist as a special district with all the powers, rights, duties, obligations, and functions provided for by the Water Code. The reorganization of the District became effective November 1, 2000 with the Laguna Beach City Council members sworn into office as the Ex-Officio Board of Directors (Board). The Board meets quarterly. A five-member Commission is appointed by the Board to serve in an advisory capacity. The Commission meets once per month. The District serves potable water to a population of approximately 19,225 people within a portion of the City of Laguna Beach, including small areas of unincorporated lands, through 8,636 service connections. Since the 1940’s, the District has relied 100 percent on imported water from the Metropolitan Water District of Southern California (MWD) through the Municipal Water District of Orange County (MWDOC). The District’s service area, shown on Figure 1, is largely built out with primarily single-family homes and some commercial uses.
