Oak Park is a census-designated place located in the Simi Hills, in Ventura County, California. As of the 2010 census, Oak Park had a population of 14,266, down from 14,625 at the 2000 census. It is located in the Conejo Valley, north from Malibu and Agoura Hills and is a part of Ventura County.
Oak Park has had human occupation from about 5500 B.C. to the present day. It lies within a zone including the early Millingstone Horizon and inland Chumash Indians. Indians camped throughout the area as they collected acorns, yucca, and other food. The sites in the area include major villages, smaller camps and several rock shelters.
The location of Oak Park was originally part of Rancho Simi, a Spanish land concession in Alta California given in 1795 to Francisco Javier Pico, a soldier of the Santa Barbara company, and his two brothers, Patricio Pico and Miguel Pico by the Spanish government. Lindero Canyon Road follows the western border (lindero in Spanish) of the land grant.
Oak Park was formed from ranchland owned by Cosmo Stevens 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 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, 10 miles (16 km) away, with L.A. County services responding when able.
In 1967 Ventura County officials who were concerned about the isolation of the community proposed a land swap with L.A. County, but they were rebuffed. The isolation—coupled with the distance to junior and senior high schools—also drove down the property values, and homeowners found it difficult to sell their properties.
The Ventura County Board of Supervisors created a Municipal Advisory Council (MAC) in 1975 to represent the community to County agencies. The MAC persuaded the Ventura County Board of Supervisors to trim Metropolitan Development Corp.'s initial development plan from a population of 26,000. Today there are about 15,000 residents. All available land within Oak Park has now been developed, with the remaining vacant land owned by the Rancho Simi Recreation and Park District.
The community was initially served by the Simi Valley Unified School District, with the nearest post-elementary schools being Sinaloa Junior High (about 20 miles (32 km) away) and Royal High (about 22 (35 km) miles away). Since the Simi Valley Unified School District had no plans to build post-elementary schools in Oak Park, the residents seceded and formed Oak Park Unified School District in June 1977. Oak Park High School opened for classes (initially grades 6-12) in the spring of 1981.
In 1999 the United States Postal Service assigned Oak Park its own ZIP code, 91377. Oak Park previously shared the ZIP code 91301 with its neighboring town of Agoura Hills.
Oak Park is located at 34°10'18" North, 118°45'28" West (34.171756, -118.757899). It is bordered by the Santa Monica Mountains National Recreational Area on the north and east and Rancho Simi Open Space on the south. It sits within valleys in the Simi Hills capped by Simi Peak which borders the community to the north. The elevation in Oak Park varies from 960 to 2,157 feet above sea level. (Does not include Simi Peak at 2,450 ft)
The CDP has a total area of 5.29 sq mi (13.7 km2). All of the area is land and none of it is covered by water. However, there are many small creeks in the area. The largest of these creeks are Medea Creek and Lindero Creek, which are tributaries of Malibu Creek, the only waterway that pierces the Santa Monica Mountains. The Malibu Creek watershed covers 105 square miles and contains 225 stream segments.

Flora and Fauna
85 species of birds have been observed with breeding activity of 32-64 probable. 12 species of raptors were observed. Nesting of 7 was confirmed including American Kestrel (Falco sparverius), Barn Owl (Tyto alba), Screech Owl (Otus asio), Red-shouldered Hawk( Buteo lineatus). The Turkey vulture (Cathartes aura) and the Prairie Falcon (Falco mexicanus) breed on adjacent slopes. Cooper’s Hawk (Accipiter cooperi) and Northern Harrier (Circus cyanus) may nest in Oak Park. Golden Eagles (Aquila chrysaetos) lack suitable nesting habitats and probably live in nearby areas. Two non-raptor birds are classified as sensitive including Coastal Black-Tailed Gnatcatcher ( Polioptila melanura californica). Possibly less than 1600 pairs of this bird remain alive. The second is Grasshopper Sparrow (Ammodramus savannarum).
Three species of amphibians were observed in Oak Park: Western toad (Bufo boreas), Pacific treefrog (Hyla regilla), and Bullfrog (Rana catesbeiana). 8 other amphibians occur in this area and may be present.
The Oak Park area and the Simi Hills are part of a wildlife corridor that link the San Gabriel Mountains (Los Padre National Forest) and Santa Susana Mountains to the Santa Monica Mountains. This is a critical path between mountain ranges where animals can find others of the same species for mating.
Oak Park ecosystems include several within the Chaparral (inland sage scrub, rocklands, northern slope chaparral scrub, southern slope chaparral scrub) and Riparian Woodland (coast live oak riparian forest, valley oak woodland, southern willow scrub, Walnut stands, and oak savanna). Southern California Grassland has largely disappeared from the site by overgrazing and housing.
The chaparral and grassland are frequently altered by fires started by natural causes and humans. Both Indians and ranchers have altered the local landscape through fire and grazing. Oak Park's last large uncontrolled fire was on October 8, 1982.
The recorded flora during the last EIR of Oak Park included 202 vascular plant species distributed among 52 families. Half are found in 5 families: sunflower(Asteraceace), grass (Poaceae), pea (Fabaceae), Mustard (Brassicaceae) and figwort (Scrophulariaceae). Non-native plants constitute 13% of the flora. There are 4 plants classified as sensitive: Catalina Mariposa Lilly (Calochortus catalinae), Wind poppy (Stylomecon heterophylla), Santa Susana Tarweed (Hemizonia minthornii ), and Nolina Parii
