Channel Islands Beach is an unincorporated community in Ventura County, California, United States consisting of two neighborhoods: Hollywood Beach and Silver Strand Beach. This densely populated narrow along the coastal edge of the Oxnard Plain was subdivided using the glamor of Hollywood to sell lots in the mid 1920s since the sand dunes had been used for movies. Adjacent development has left this neighborhood hemmed in by Channel Islands Harbor and Naval Base Ventura County. The harbor mouth separates the two neighborhoods resulting in a round-about travel route around the harbor between them although the Channel Islands Beach Community Services District provides local utilities services to both neighborhoods. The Special-purpose district has an elected Board of Directors which provides a forum for the unique concerns of the community. Lying immediately adjacent but outside the corporate boundaries of the City of Oxnard and the City of Port Hueneme, they are governed by the county Board of Supervisors.
