Oxnard Plain
The Oxnard Plain is a large coastal plain in southwest Ventura County, California, United States surrounded by the mountains of the Transverse ranges. The cities of Oxnard, Camarillo, Port Hueneme and much of Ventura as well as the unincorporated communities of Channel Islands, El Rio, Saticoy and Somis lie within the over 200-square-mile alluvial plain (520 km2). The 16.5-mile-long coastline (26.6 km) is among the longest stretches of continuous, linear beaches in the state.
The high quality soils, adequate water supply, favorable climate, long growing season, and level topography are characteristic of the Oxnard Plain where the top cash crops are strawberries, raspberries, nursery stock and celery. Ventura County is one of the principal agricultural counties in the state and it is a significant component of the economy with a total annual crop value in the county of over $1.8 billion in 2014. There is strong public sentiment for retaining agricultural production, as reflected in the SOAR (Save Open Space and Agricultural Resources) initiatives that have been approved by voters.
This plain has been formed chiefly by the deposition of sediments from Santa Clara River and Calleguas Creek. This plain contained a series of marshes, salt flats, sloughs, and lagoons prior to the expansion of agriculture. The Santa Clara River is one of the largest river systems along the coast of Southern California and only one of two remaining river systems in the region that remain in their natural states. The Oxnard Plain section of the Southern California Bight extends from the abrupt transition of the steep rocky shore at Point Mugu in the Santa Monica Mountains on the south to the Ventura River on the north. It is bounded by the Santa Monica Mountains, the Santa Susana Mountains, the Topatopa Mountains to the north, the Santa Clara River Valley to the northeast and the Pacific Ocean to the south and west. Lying within the plain are which comprise a majority of the western half of the Oxnard-Thousand Oaks-Ventura Metro Area.
