Las Positas College is a community college located in Livermore, California, United States, on 147 acres (0.59 km). It 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. The Chabot-Las Positas Community College District purchased the Livermore site that same year, intending to develop a comprehensive community college. 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 March 31, 1975, "Valley Campus" opened as the Livermore Education Center of Chabot College. Las Positas College has since developed into a fully accredited comprehensive institution.
