The community of Westlake Village CA has somewhat of an identity crisis. Some of it is its own incorporated city, while other neighborhoods are stuck within the city limits of Thousand Oaks. This situation arose because Westlake Village CA suffered two annexations before finally incorporating as its own city in 1981. Today Westlake Village CA is known for the affluence of its residents and the secluded character of its neighborhoods.
