Rancho Dominguez, California
Rancho Dominguez is a former settlement, now an unincorporated community, in Los Angeles County, California. It was located near East Rancho Dominguez. Rancho Dominguez is located between Long Beach, California and Carson, California.
The Communities of Unincorporated Rancho Dominguez are East Rancho Dominguez, West Rancho Dominguez and Rancho Dominguez. Originally Rancho Dominguez contained the cities of Compton, California, Carson, California & a portion of North Long Beach, California.
The entire Rancho Dominguez area has a rich history. Originally Rancho Dominguez was a small part of the Spanish land grant Rancho San Pedro from the King of Spain in 1784. The Dominguez Rancho Adobe Museum on South Alameda Avenue is the historic ranch home of land grantee Juan Dominguez and Manuel Dominguez, the men for whom the area is named. The Dominguez family lived in the home until the 1920s and it is now a retirement home for Claretin Catholic priests.
In the late 1800s most of the southern part of Rancho Dominguez and the land leading down to the Los Angeles Harbor was acquired by the railroad industry. Today these railroad tracks are used for the same purpose, and is a valuable tie between the Port of Los Angeles and Downtown Los Angeles.
Rancho Dominguez was home to California State University, Dominguez Hills but when the City of Carson gained cityhood in 1967, it incorporated the Dominguez Hills section of Rancho Dominguez.
Present day 
The Los Angeles County Sheriffs from the Carson's Sheriff Station patrol West Rancho Dominguez & Rancho Dominguez. East Rancho Dominguez is patrolled by the Lynwood Sheriff Station.
Annexation efforts 
The city of Compton has tried multiple times to annex East Rancho Dominguez known as East Compton and shares Compton's zip code of 90221. West Rancho Dominguez shares that same zip code but Compton has no interest in annexing that part of unincorporated Los Angeles County due to a lot of Environment Waste type of Industry/business in that region. The Community of Rancho Dominguez south of Compton is a Warehousing and Transportation Industry area that collects great tax revenue for the County of Los Angeles.
