and the Masters in Public Health Program. USC was developed under two master plans drafted and implemented some 40 years apart. The first was prepared by the Parkinsons in 1920, which guided much of the campus's early construction and established its Romanesque style and 45-degree building orientation. The second and largest master plan was prepared in 1961 under the supervision of President Norman Topping, campus development director Anthony Lazzaro, and architect William Pereira. This plan annexed a great deal of the surrounding city, and many of the older nonuniversity structures within the new boundaries were leveled. Most of the Pereira buildings were constructed in the 1970s. Pereira maintained a predominantly red-brick architecture for the new buildings, but infused them with his trademark technomodernism stylings. More recently under President C. L. Max Nikias, the architectural orientation of the campus has moved towards a Gothic Revival style, taking cues from the scholastic styles of Oxford University and Harvard University, while underpinning USC's own historic identity that is present in the red-brick construction. USC's role in making visible and sustained improvements in the neighborhoods surrounding both the University Park and Health Sciences campuses earned it the distinction of College of the Year 2000 by the Time/Princeton Review College Guide. Roughly half of the university's students volunteer in community-service programs in neighborhoods around campus and throughout Los Angeles. These outreach programs, as well as previous administrations' commitment to remaining in South Los Angeles amid widespread calls to move the campus following the 1965 Watts Riots, are credited for the safety of the university during the 1992 Los Angeles Riots. (That the university emerged from the riots completely unscathed is all the more remarkable in light of the complete destruction of several strip malls in the area, including one just across Vermont Avenue from the campus's western security fence.) The ZIP Code for USC is 90089 and that of the surrounding University Park community is 90007. USC has an endowment of $8.1 billion and carries out nearly $1 billion per year in sponsored research. USC became the only university to receive eight separate nine-figure gifts: $120 million from Ambassador Walter Annenberg to create the Annenberg Center for Communication and a later additional gift of $100 million for the USC Annenberg School for Communication; $112.5 million from Alfred Mann to establish the Alfred E. Mann Institute for Biomedical Engineering; $110 million from the W. M. Keck
