The area was considered territory of the Yokuts people, but Chumash Indians from the Pacific Coast are also known to have frequented the area. The imprint of an old Indian trail can still be seen leading over the hills of present-day Ventura County to the headwaters of Piru Creek. The name "Cuyama" comes from an Indian village named for the Chumash word kuyam, meaning "clam" or "freshwater mollusk".[2]
Following the 1949 discovery of oil at the South Cuyama Oil Field, in 1952 the Atlantic Richfield Company (ARCO) settled and developed the town of New Cuyama, building housing and associated commercial business – including the New Cuyama Airport (L88), reopened in May 2015,[3][4] which bears the distinction of being the only public-use paved airport within easy flying range of Los Angeles for more than 50 miles (80 km).[citation needed] Much of the infrastructure from ARCO's settling of the town still exists today and is used by town residents. The original ARCO-built gas processing plant is still in use and easily seen due south of New Cuyama, though ARCO has since sold off interest in the facility.[5]
The town of New Cuyama, at its founding, was considered the pearl of eastern Santa Barbara County, due to the flow of oil that was coming out of the region. During this time Richfield Oil Company built the town funded schools and provided all the important utilities other than electricity. Now that oil and gas production have declined, the principal industry is once again agriculture.
In 2024, Santa Barbara County approved the construction of a mixed-use development project, including 33 residential units, in New Cuyama.[6]
