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, celery, tomatoes, lima beans, peppers, and cut flowers. 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.
