Oak Park was formed from ranchland owned by Jim and Marian Jordan, stars of the radio show "Fibber McGee and Molly". The land was purchased by Metropolitan Development Corporation in the 1960s. Homes were developed starting in the late 1960s. Kanan-Dume Road (named after a local family) was the only access road to the community, from Agoura Hills, California, in neighboring Los Angeles County. As such, the community was served by police and firefighters based in the nearest Ventura County city, Thousand Oaks, away, with L.A. County services responding when able.
