"Celebrate UCI" open house. It also hosts many extracurricular activities. Ring Mall is the main pedestrian road used by students and faculty to travel around the core campus. The road measures up to a perfect mile and completely encircles Aldrich Park. Most schools and libraries are lined up by this road with each of these schools having their own central plaza which also connects to the Aldrich Park. Other areas of the university outside of the core campus such as the School of Arts are connected by four pedestrian bridges. Beyond the core campus and the bridges, the layout of the campus is more suburban. Surroundings Irvine, California consistently ranks as the safest city in America. UCI is close to the beaches, mountains, and attractions of Southern California. Disneyland is approximately 20 minutes away by car. While the university is located in Irvine, the campus is directly bounded by the city of Newport Beach and the community of Newport Coast. The western side of the campus borders the San Diego Creek and the San Joaquin Freshwater Marsh Reserve, through which Campus Drive connects UCI to the 405 freeway. The northern and eastern sides of UCI are adjacent to Irvine proper; the eastern side of the campus is delineated by Bonita Canyon Road, which turns into Culver Drive at its northern terminus. California State Route 73 marks UCI's southern boundary and separates the campus from Newport Beach. The "North Campus" houses the Facilities Management Department, the Faculty Research Facility, Central Receiving, Fleet Services, the Air Pollution Health Effects Laboratory, and numerous other functions. It is located next to the UCI Arboretum; both the North Campus and the arboretum are located about from the main campus. William Pereira's original street layout for the region surrounding the University had a wingnut-shaped loop road as the main thoroughfare, which twice crossed the campus. However, the Irvine Company's development plans expanded before it could be completed, and portions of California, Carlson, Harvard and Turtle Rock roads today constitute segments of what would have been the Loop Road. Despite the suburban environment, a variety of wildlife inhabits the university's central park, open fields, and wetlands. The university is home to cougar, hawks, golden eagles, great blue herons, squirrels, opossums, peregrine falcons, rabbits, raccoons, owls, skunks, weasels, bats, and coyotes. The UCI Arboretum hosts a collection of plants from California and Mediterranean climates around the world. The
