employer in Orange County, with an annual economic impact of $5 billion. Aldrich developed the campus' first academic plan around a College of Arts, Letters, and Science, a Graduate School of Administration, and a School of Engineering. The College of Arts, Letters, and Science was composed of twenty majors in five "Divisions": Biological Sciences, Fine Arts, Humanities, Physical Sciences, and Social Sciences (which transformed into the present-day "Schools"). In 1967, the California College of Medicine (originally a school of osteopathy founded in 1896 and the oldest continuously operating medical college in the Southwest) became part of UC Irvine. In 1976, plans to establish an on-campus hospital were set aside, with the university instead purchasing the Orange County Medical Center (renamed the UC Irvine Medical Center) around 12 miles from UC Irvine, in the City of Orange. In early July 2018, UC Irvine removed benefactor Francisco J. Ayala's name from its biology school and central science library after an internal investigation by the university's Office of Equal Opportunity and Diversity substantiated a number of sexual harassment claims. Chancellor Gillman also authorized the removal of the Ayala name from graduate fellowships, scholar programs, and endowed chairs. Ayala resigned July 1, 2018 and was ordered to abstain from future university activities, following the university's consultative procedures that include a faculty review committee. The results from the investigation were compiled in a 97-page report, which included testimony from victims of Ayala. Campus The layout of the core campus resembles a rough circle with its center being Aldrich Park (initially known as Central Park), lined up by the Ring Mall and buildings surrounding the road. To further emphasize the layout, academic units are positioned relative to the center, wherein undergraduate schools are closer to the center than the graduate schools. Aldrich Park is planted with over 11,120 trees (there are over 24,000 trees on the entire campus), including 33 species of eucalyptus. Two ceremonial trees were planted in 1990, one for Arbor Day and the second for former chancellor Daniel Aldrich who had died that year. On the first anniversary of the September 11th tragedies, the chancellor planted a bay laurel tree in remembrance of the heroes and victims of the events of September 11, 2001. The tree itself was a gift from the UCI Staff Assembly. Aldrich Park is the site for "Wayzgoose", a medieval student festival held each year in conjunction with the
