About the Tri-Valley Region
Nestled in a triangle shaped area just east of the San Francisco Bay Area and west of the California Central Valley is the Tri Valley Region. It is primarily comprised of the cities of San Ramon, Pleasanton and Livermore.
Although a major bedroom community for San Francisco and the Silicon Valley, this region hosts many large employers such as Chevron, AT&T, Bank of the West, Safeway, Ross Stores and Lawrence Livermore Laboratory.
It is a fast growing and sought after area, as people move to escape the high cost of living and congestion of the San Francisco Bay Area.
Originally inhabited by the Ohlone American Indian peoples, the region fell under Spanish rule from the Mission San Jose located in nearby Fremont. After a brief Mexican administration the area became part of the United States in 1848 following the Mexican-American War.
