needs; in 1905, the Legislature established a "University Farm School" at Davis and in 1907 a "Citrus Experiment Station" at Riverside as adjuncts to the College of Agriculture at Berkeley. In 1912, UC acquired a private oceanography laboratory in San Diego, which had been founded nine years earlier by local business promoters working with a Berkeley professor. In 1944, UC acquired Santa Barbara State College from the California State Colleges, the descendants of the State Normal Schools. In 1958, the regents began promoting these locations to general campuses, thereby creating UCSB (1958), UC Davis (1959), UC Riverside (1959), UC San Diego (1960), and UCSF (1964). Each campus was also granted the right to have its own chancellor upon promotion. In response to California's continued population growth, UC opened two additional general campuses in 1965, with UC Irvine opening in Irvine and UC Santa Cruz opening in Santa Cruz. The youngest campus, UC Merced opened in fall 2005 to serve the San Joaquin Valley. After losing campuses in Los Angeles and Santa Barbara to the University of California system, supporters of the California State College system arranged for the state constitution to be amended in 1946 to prevent similar losses from happening again in the future. With decentralization complete, it was decided in 1986 that the UC president should no longer be based at the Berkeley campus, and the UC Office of the President moved to Kaiser Center in Oakland in 1988. That lakefront location was subject to widespread criticism as "too elegant and too corporate for a public university". In 1998, the Office of the President moved again, to a newly constructed but much more modest building near the former site of the College of California. Modern history The California Master Plan for Higher Education of 1960 established that UC must admit undergraduates from the top 12.5% (one-eighth) of graduating high school seniors in California. Prior to the promulgation of the Master Plan, UC was to admit undergraduates from the top 15%. UC does not currently adhere to all tenets of the original Master Plan, such as the directives that no campus was to exceed total enrollment of 27,500 students (in order to ensure quality) and that public higher education should be tuition-free for California residents. Five campuses, Berkeley, Davis, Irvine, Los Angeles, and San Diego each have current total enrollment at over 30,000. After the state electorate severely limited
