El Rio ( ; Spanish: El Río, meaning "The River") is a small, rural unincorporated town in Ventura County, California, United States, on the northeast side of the 101 Freeway and Oxnard, and south of the Santa Clara River. The town was founded in 1875 and named New Jerusalem by the owner of general store who became the first postmaster in 1882. In 1885, a school and Santa Clara Catholic Church were built. Located near where the coastal railroad line crosses the Santa Clara River, the town's name was changed to El Rio around 1900. The former wagon river crossing route became the Ventura Freeway which separates the community from the commercial developments that grew up on the southwest side of the freeway. That portion of the historic community and sections closer to the river have been annexed to the city of Oxnard. Vineyard Avenue (State Route 232) is the central business district for the largely residential community. The population was 7,198 at the 2010 census, up from 6,193 at the time the 2000 census was enumerated. For statistical purposes, the United States Census Bureau has defined a portion of the unincorporated area as El Rio census-designated place (CDP) which does not precisely correspond to the historical community that is much larger with significant portions having been annexed to the city of Oxnard.

Saticoy ( ; Chumash: Sa'aqtik'oy) is an unincorporated community in Ventura County, California, United States. The settlement was laid out in 1887 along the railroad line that was being built from Los Angeles through the Santa Clara River Valley to the town of San Buenaventura. Although the town was 10 miles (16 km) distant at that time, the City of Ventura grew to a point where the community is now just outside the city limits. For statistical purposes, the United States Census Bureau has defined Saticoy as a census-designated place (CDP).The commercial district known as Old Town Saticoy is surrounded by a residential neighborhood with a population of just over one thousand. Two historic buildings attest to the important role Saticoy once held in the local agricultural economy: Walnut Growers Association Warehouse, and Saticoy (Lima) Bean Warehouse. The historic setting, stable residential population, railroad, and access to major highways make this community unique in Ventura County.South towards the Santa Clara River is a sizable industrial area located on both sides of Los Angeles Avenue. The historic building that formerly housed the Farmers & Merchants Bank of Santa Paula, Saticoy Branch, stands at a quiet intersection that used to be at the center of a vibrant community.
