Manhole Covers of San Francisco, San Francisco County, California

San Francisco is a large but compact urban city on the tip of the San Francisco Peninsula in San Francisco County, at an average elevation of around 300 feet above sea level.   San Francisco was a port city, named early on in the 1500s by Spanish explorers to the Bay Area.   San Francisco was founded in 1776 as the Spanish Presidio of San Francisco and Mission Dolores.   San Francisco currently has a population of about 799,183 people (2007).   San Francisco citizens are composed of 45.0% Caucasians, 14.0% Hispanics, 33.1% Asian, and 7.3% Black.   The median household income for San Francisco residents is $67,489 and the per capita income is $33,076.   San Francisco is home to a campus of San Francisco University, University of California, San Francisco, and California State University San Francisco.   About 42.5% of San Francisco residents have earned a bachelor's degree or higher, well over the national average.

Beacon Hill is the prominant topographic feature of the San Francisco Peninsula.   San Francisco is severed by the San Francisco Public Utilities Commission, which received most of its water from the Sierra Nevada, from the Hetch Hetchy Reservior, via a canal system that stores that water in the Crystal Springs Reservoir in San Mateo County.

San Francisco, other than the home to Native Americans prior to the arrival of the Spaniards, was first settled as a Spanish Presidio, or military installation.   It was also settled by Spaniards and Mexicans with the establishment of the Franciscan mission.   San Francisco became an important port for emigrants and trade during the California Gold Rush beginning in 1949.

Four highways pass through or terminate in San Francisco, Interstate 80, Interstate 280, U.S. Highway 101, and State Route 1.   Only about 16% of employed residents of San Francisco work there.   Additional information about San Francisco can be found at San Francisco Info and at the Official San Francisco site.
