Westlake Village is a planned community that straddles the Los Angeles and Ventura county line. The eastern portion is the incorporated city of Westlake Village, located on the western edge of Los Angeles County, California. The city, located in the region known as the Conejo Valley, encompasses half of the area surrounding Westlake Lake, and small neighborhoods primarily south of U.S. Route 101 and east of La Venta Drive. The population was 8,270 at the 2010 census, down from 8,368 at the 2000 census. It is also the headquarters of the Dole Food Company. Westlake Village is known for its affluence and secluded character, and is considered one of the wealthiest communities in the Greater Los Angeles Area.
The western portion of Westlake Village is a community, within the city limits of Thousand Oaks, in Ventura County. The properties and businesses in this portion can be addressed as “Westlake Village”, as the United States Post Office maps both 91361 and 91362 ZIP codes to this area. Built across the county line as a planned development, residents recognize that the community of Westlake Village is not limited to the incorporated city in Los Angeles County, but encompassing the entire area surrounding the lake. The original community was known simply as “Westlake”. 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 eventually incorporated as the City of Westlake Village.
Dole Food Company is headquartered in Westlake Village. In 1994 Dole announced that it would finalize its plans to build its world headquarters on a 30-acre (120,000 m2) site owned by the company, located north of the Ventura Freeway in Westlake Village. The decision had been delayed by groundwater contamination tests and reviewing of possible site plan revisions. Dole was expected to submit its plans for final approval by the Westlake Village City Council on February 9, 1994. K-Swiss, Guitar Center, ValueClick, and Ryland Homes also have their headquarters in Westlake Village. American Luxury Limousine also has their headquarters here.
