air-conditioning utilities from the Central Plant. These tunnels have been the subject of much campus lore, the most popular story being that the tunnels were constructed to facilitate the safe evacuation of faculty in the event of a student riot. The main tunnel actually contains an above-ground section, in the form of the interior of an unusually thick pedestrian bridge near the Engineering Tower, in an area where the Ring Mall crosses between two hills. The tunnels are only accessible to maintenance staff, although there are also publicly accessible tunnels which intersect the utility tunnels, such as the one that goes between the main Information & Computer Science building and the Engineering Tower. Governance Like other University of California campuses, UC Irvine operates under a system of shared governance, or a partnership between the Chancellor and his administration and the faculty through the Academic Senate. The Chancellor is the chief campus officer and has authority over the campus budget. The Academic Senate has authority to determine the conditions for admission and supervise courses and curricula. The Chancellor is nominated by and is responsible to the Regents of the University of California and the UC President. UCI's Chancellors are listed below: 1962 Daniel G. Aldrich 1984 Jack W. Peltason 1993 Laurel L. Wilkening 1998 Ralph J. Cicerone 2005 Michael V. Drake 2014 Howard Gillman After the Chancellor, the second most senior official is the Executive Vice Chancellor and Provost, the university's chief academic and operating officer. Every school on campus reports to the Executive Vice Chancellor and Provost through a Dean, and all other academic and administrative units report to his office through a Vice Chancellor or chief administrator. A partial list of these units includes Campus Recreation, Intercollegiate Athletics, Planning and Budget, Student Affairs, UC Irvine Libraries, UC Irvine Medical Center, and University Advancement. Academics Academic units UC Irvine's academic units are referred to as Schools. As of the 2021-2022 school year, there are fourteen Schools, one Program in Public Health, and various interdisciplinary programs. The College of Health Sciences was established in 2004, but no longer exists as a separate academic unit. On November 16, 2006, the University of California Regents approved the establishment of the School of Law. The School of Education was established by the UC Regents in 2012. In 2016, the university announced that it had received a $40 million donation from Bill Gross' philanthropic foundation
