Berkeley Hills
The Berkeley Hills are a range of the Pacific Coast Ranges, and overlook the northeast side of the valley that encompasses San Francisco Bay. They were previously called the "Contra Costa Range/Hills" (from the original Spanish Sierra de la Contra Costa), but with the establishment of Berkeley and the University of California, the name was updated by geographers and gazetteers.
The Berkeley Hills are bounded by the major Hayward Fault along their western base, and the minor Wildcat fault on their eastern side. The highest peaks are Grizzly Peak with an elevation of 1,754 feet (535 m) and Round Top, an extinct volcano with an elevation of 1,761 feet (537 m) and William Rust Summit at an elevation of 1,004 feet (306 m).
Vollmer Peak (elevation 1,905 feet/581 m), although commonly thought to be part of the Berkeley Hills, is actually located on the adjacent San Pablo Ridge[dubious – discuss] near the point where it meets the Berkeley Hills at the head of Wildcat Canyon. Vollmer Peak was named in honor of the first police chief of the City of Berkeley, August Vollmer. It was formerly known as "Bald Peak", and as "Rocky Mound" in the 19th century.
Over time, the widespread deposition of loose sediments along the hillsides, along with fracturing from the fault and other factors make these hills susceptible to landslides. These landslides are more likely to be caused by precipitation than by a seismic event.
Much of the west slope of the Berkeley Hills has residential neighborhoods of mostly single family homes, except on the land of University of California, Berkeley. Most streets are narrow and tend to follow the contours of the terrain, although three streets, Marin Avenue, Moeser Lane, and Potrero Avenue, run directly toward the ridgeline. Other roads to the ridgeline wind their way up the canyons. Grizzly Peak and Skyline Boulevards follow the top of the ridge. Many neighborhoods in the Berkeley Hills are home to the more affluent residents of Berkeley and Oakland.
Preservation
The east slope of the Berkeley Hills is mostly preserved or partially developed wildland, much of it owned by the East Bay Regional Park District and the East Bay Municipal Utility District (EBMUD). From north to south, the parks are Wildcat Canyon Regional Park, Tilden Regional Park (includes Vollmer and Grizzly Peaks), Sibley Volcanic Regional Park (includes Round Top), Huckleberry Botanic Regional Preserve, Redwood Regional Park (enfolding Roberts Regional Recreation Area), Anthony Chabot Regional Park, Lake Chabot Regional Park, and Cull Canyon Regional Recreation Area. Claremont Canyon Regional Preserve, and Temescal Regional Park are lower on the western slopes while Las Trampas Regional Wilderness is lower on the eastern slope above Danville.
