Westlake Village California
- Category: Cities
The planned community of Westlake was built with a lake at the center straddling the line between Los Angeles and Ventura counties. Roughly two-thirds of it was annexed by the city of Thousand Oaks in two portions, in 1968 and 1972. In 1981, the remaining third incorporated into the City of Westlake Village which became the 82nd municipality of Los Angeles County.
