Warner Center is a business development in the Woodland Hills neighborhood of the San Fernando Valley in Los Angeles, California. Warner Center, which began as a master-planned area, is designated as a Regional Center within the City’s Canoga Park-West Hills-Winnetka-Woodland Hills Community Plan. Historically, Warner Center is generally bounded by Vanowen Street to the north, the Ventura Freeway to the south, De Soto Avenue to the east, and Topanga Canyon Boulevard on the west. The Warner Center 2035 Plan (adopted in December 2013) added the area between Vanowen and the LA River to the plan area, which comprises approximately 1,100 acres or 1.7 square miles.
