Kensington (formerly, Kensington Park) is an unincorporated community and census-designated place located in the East Bay, part of the San Francisco Bay Area, in Contra Costa County, California, United States. The population was 5,077 at the 2010 census.
Kensington is an unincorporated area of Contra Costa County that borders Alameda County. Unlike many unincorporated communities, Kensington has local jurisdiction over its police department, park services, refuse collection and fire department. These are governed by two elected boards: the five-member Kensington Police Protection and Community Services District (KPPCSD) Board which oversee the police department, park services and refuse collection and the five-member Kensington Fire District Board which oversee the fire department and emergency medical services, of which the day-to-day function is outsourced to the fire department of El Cerrito, a neighboring community. A citizen commission, the Kensington Municipal Advisory Board (KMAC), reviews development plans and makes recommendations to the county Public Works department.
The area that is now Kensington was originally the territory of the Huichin band of the Ohlone indigenous people who occupied much of the East Bay of the San Francisco Bay Area.
