San Francisco Bay Area
The San Francisco Bay Area, often referred to as simply the Bay Area, is a populous region surrounding the San Francisco, San Pablo, and Suisun Bay estuaries in Northern California. The Bay Area is defined by the Association of Bay Area Governments to include the nine counties that border the aforementioned estuaries: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties that do not border the bay such as Santa Cruz and San Benito (more often included in the Central Coast regions); or San Joaquin, Merced, and Stanislaus (more often included in the Central Valley). The core cities of the Bay Area are San Francisco, San Jose, and Oakland.

Las Positas College
Las Positas College (LPC) is a public community college in Livermore, California. History Las Positas College began as an extension program of Chabot College in 1963, offering 24 classes and enrolling 810 students at three sites, including Livermore High School. By 1965, the program had expanded to Granada High School in Livermore and subsequently offered classes at Amador and Dublin High Schools as well.

However, in 1970 and again in 1972, bond issues to build the rural college failed despite Tri-Valley voters' overwhelming support, ostensibly because of opposition among the District's largest voting population, who lived outside the service area for the proposed college. Lacking funds to develop a second comprehensive community college, the Board of Trustees voted to develop a small education center at the Livermore site. On ...

The longitudinal valley is bordered on the west by the Santa Cruz Mountains and on the east by the Diablo Range; the two coastal ranges meet south of Hollister.
