About San Simeon Community Services District

San Simeon, a small unincorporated community situated within San Luis Obispo County on California’s central coast, is located along State Highway 1 approximately halfway between Los Angeles and San Francisco. The San Simeon community is bordered on the east side by open space owned by the Hearst Corporation, and the north and south sides by State Parks property. As an aside, Hearst Castle is visible from portions of the District. The community is located on a coastal plain, bordered by the Pacific Ocean on the west and the Santa Lucia mountain range on the east.

Originally called San Simeon Acres, the community water and wastewater systems have been developed over many decades based on the originally purchased infrastructure. San Simeon’s development occurred primarily in the 1960s and continued in the 1970s. A moratorium on the issuance of water and sewer connections within the District's boundaries has been in place since the mid-1990s.



Our office is located at:
111 Pico Avenue
San Simeon, CA


The community is governed by a five-member elected Board of Directors. Our Board meetings are held on the 2nd Tuesday of every month at 5:00 PM. Board members can be contacted via email.
