Victor Girard Kleinberger bought 2,886 acres in the area and founded the town of Girard in 1922. He sought to attract residents and businesses to Woodland Hills Real Estate by developing an infrastructure, advertising in newspapers, and planting 120,000 trees. Although his early efforts were criticized as providing only dubious facade of economic activity (local lore has it that in order to attract development he erected false store fronts on Ventura Boulevard, for which he spent time in jail), the Girard Golf Course completed in 1925 continues to operate today as the Woodland Hills Country Club, and his scheme was ultimately successful in attracting interest in the community.

In 1941, the community was renamed Woodland Hills, an appropriate name owing to all the trees that Girard had planted years earlier. Harry Warner bought 1,100 acres in the area in the 1940s for a horse ranch. The modern Warner Center commercial zone near Woodland Hills Homes for Sale is named for Harry and features high-rise buildings, hotels, and shopping centers. A major transit hub — the western end of the Orange Line — opened here in October 2005. The population of approximately 70,000 makes up the Woodland Hills CA homes. The area is known around "The Valley."
