The Key System was a privately owned company that provided mass transit in the cities of Oakland, Berkeley, Alameda, Emeryville, Piedmont, San Leandro, Richmond, Albany, and El Cerrito in the eastern San Francisco Bay Area from 1903 until 1960, when it was sold to a newly formed public agency, AC Transit. The Key System consisted of local streetcar and bus lines in the East Bay, and commuter rail and bus lines connecting the East Bay to San Francisco by a ferry pier on San Francisco Bay, later via the lower deck of the Bay Bridge. At its height during the 1940s, the Key System had over 66 miles (106 km) of track. The local streetcars were discontinued in 1948 and the commuter trains to San Francisco were discontinued in 1958. The Key System's territory is today served by BART and AC Transit bus service.

Alameda Creek is a large perennial stream in the San Francisco Bay Area. The creek runs for 45 miles (72 km) from a lake northeast of Packard Ridge to the eastern shore of San Francisco Bay by way of Niles Canyon and a flood control channel. Along its course, Alameda Creek provides wildlife habitat, water supply, a conduit for flood waters, opportunities for recreation, and a host of aesthetic and environmental values. The creek and three major reservoirs in the watershed are used as water supply by the San Francisco Public Utilities Commission, Alameda County Water District and Zone 7 Water Agency. Within the watershed can be found some of the highest peaks and tallest waterfall in the East Bay, over a dozen regional parks, and notable natural landmarks such as the cascades at Little Yosemite and the wildflower-strewn grasslands and oak savannahs of the Sunol Regional Wilderness. After an absence of half a century, ocean-run steelhead trout are able to return to Alameda Creek to mingle with remnant rainbow trout populations. Completion of a series of dam removal and fish passage projects, along with improved stream flows for cold-water fish and planned habitat restoration, enable steelhead trout and Chinook salmon to access up to 20 miles (32 km) of spawning and rearing habitat in Alameda Creek and its tributaries. The first juvenile trout migrating downstream from the upper watershed through lower Alameda Creek toward San Francisco Bay was detected and documented in April 2023.

Cerrito Creek is one of the principal watercourses running out of the Berkeley Hills into San Francisco Bay in northern California. It is significant for its use as a boundary demarcation historically, as well as presently. In the early 19th century, it separated the vast Rancho San Antonio to the south from the Castro family's Rancho San Pablo to the north. Today, it marks part of the boundary between Alameda County and Contra Costa County. The main stem, running through a deep canyon that separates Berkeley from Kensington, is joined below San Pablo Avenue by a fan of tributaries, their lower reaches mostly in culverts. The largest of these is Middle or Blackberry Creek, a southern branch.
The Eastshore and Suburban Railway (E&SR) was a formerly independent unit of the historic San Francisco Bay Area Key System which ran streetcar trains in Richmond, California, San Pablo, and El Cerrito. There were several lines with terminals at Point Richmond, North Richmond, the county line with Alameda County, what is now San Pablo, and Grand Canyon/East Richmond/Alvarado Park. Service to Oakland required a transfer to Oakland Traction Company trains at the County Line station and service to San Francisco required an additional transfer in Oakland. The systems were later consolidated into the Key System. Service began to be replaced by buses beginning on August 1, 1932, with the conversion of the East Richmond/23rd Street line to buses. Lines were converted to buses one at a time with the last remaining line being in September 1933. Fares were originally 5 cents and were raised to 7 cents over time at the time of the last runs.
