Oxnard

History

Before the arrival of Europeans, the area was inhabited by Chumash Native Americans. The first European to encounter the area was explorer João Rodrigues Cabrilho, who claimed it for Spain in 1542. During the mission period, Mission San Buenaventura, established in 1782, used the area for raising cattle. Ranching began to take hold among Californio settlers, who lost their regional influence when California became a US state in 1850. At about the same time, the area was settled by American farmers, who cultivated barley and lima beans. Henry T. Oxnard, founder of Moorhead, Minnesota-based American Crystal Sugar Company who operated a successful sugar beet factory with his three brothers (Benjamin, James, and Robert) in Chino, California, was enticed to build a $2 million factory on the plain inland from Port Hueneme. Shortly after the 1897 beet campaign, a new town emerged. Oxnard intended to name the settlement after the Greek word for "sugar", zachari, but frustrated by bureaucracy, named it after himself. Given the potential growth of Oxnard, in the spring of 1898, a railroad station was built to service the plant, attracting a population of Chinese, Japanese, and Mexican laborers. The Oxnard brothers, who never lived in their namesake city, sold the Chino and the giant red-brick Oxnard factory in 1899 for nearly $4 million. The Oxnard factory, with its landmark twin smokestacks, operated from August 19, 1899, until October 26, 1959. Factory operations were interrupted in the 1903 Oxnard strike. Oxnard was incorporated as a California city on June 30, 1903, and the public library was opened in 1907. A neighborhood of distinctive homes, established in 1909, has been placed on the National Register of Historic Places as the Henry T. Oxnard Historic District. Before…

Geography

Oxnard is located on the Oxnard Plain, an area with fertile soil. With its beaches, dunes, wetlands, creeks, and the Santa Clara River, the area contains several critical biological communities. Native plant communities include: coastal sage scrub, California Annual Grassland, and Coastal Dune Scrub species; however, most native plants have been eliminated from within the city limits to make way for agriculture and urban and industrial development. Also native to the region is the endangered Ventura Marsh Milkvetch, and the last self-sustaining population is in Oxnard in the center of an approved housing development. The Santa Clara River separates Oxnard and Ventura. Tributaries to this river include Sespe Creek, Piru Creek, and Castaic Creek. Oxnard is on a tectonically active plate since most of Coastal California is near the boundaries between the Pacific and North American Plates. The San Andreas Fault, which demarcates this boundary, is about 40 miles away. One active fault that transverses Oxnard is the Oak Ridge Fault, which straddles the Santa Clara River Valley westward from the Santa Susana Mountains, crosses the Oxnard Plain through Oxnard, and extends into the Santa Barbara Channel. The coastline is subject to inundation by a tsunami up to 23 feet in height. The fault has significantly contributed to seismic activity in the Oxnard region and beyond. The January 17, 1994, 6.7 Northridge earthquake is believed to have occurred in the Santa Clarita extension of the Oak Ridge Fault. Landslides and ridge-top shattering resulting from the Northridge earthquake were observed above Moorpark, a city east of Oxnard. Oxnard is the location of the National Weather Service forecast office that serves the Los Angeles area. The city is situated in a Mediterranean…
