Under UC President William Wallace Campbell, enrollment at the Southern Branch expanded so rapidly that by the mid-1920s the institution was outgrowing the 25 acre Vermont Avenue location. The Regents searched for a new location and announced their selection of the so-called "Beverly Site"—just west of Beverly Hills—on March 21, 1925, edging out the panoramic hills of the still-empty Palos Verdes Peninsula. After the athletic teams entered the Pacific Coast conference in 1926, the Southern Branch student council adopted the nickname "Bruins", a name offered by the student council at UC Berkeley. In 1927, the Regents renamed the Southern Branch the University of California at Los Angeles (the word "at" was officially replaced by a comma in 1958, in line with other UC campuses). In the same year, the state broke ground in Westwood on land sold for $1 million, less than one-third its value, by real estate developers Edwin and Harold Janss, for whom the Janss Steps are named. The campus in Westwood opened to students in 1929.
