Livermore (formerly Livermores, Livermore Ranch, and Nottingham) is a city in Alameda County. The estimated population as of 2011 was 82,039. Livermore is located on the eastern edge of California’s San Francisco Bay Area.
Livermore was founded by William Mendenhall and named after Robert Livermore, his friend and a local rancher who settled in the area in the 1840s. Livermore is the home of the Lawrence Livermore National Laboratory, for which the chemical element livermorium is named (and thus, placing the city’s name in the periodic table). Its south side is home to local vineyards. The city has also redeveloped its downtown district. The city is considered part of the Tri-Valley area, including Amador, Livermore and San Ramon Valleys.
The Livermore Valley is located about 30 miles (48 km) east of and behind the first coastal range of mountains that surround the San Francisco Bay Area. The Livermore Valley has an east-west orientation with mountain passes on the west and east connecting the San Francisco Bay Area and the Central Valley. The passes are used by railroads and highways to connect the San Francisco Bay Area and the Central Valley. Livermore Valley is about 15 miles (24 km) long (east to west), 10 miles (16 km) wide (north to south), and surrounded by California coastal range mountains and foothills.
