San Francisco General Information

San Francisco Bay DUIThe City and County of San Francisco is the 4th most populous city in California and the 14th most populous city in the United States, with a 2006 estimated population of 744,041. One of the most densely populated major cities in the U.S; San Francisco is part of the much larger San Francisco Bay Area, which is home to approximately 7.2 million people.

The city is located on the tip of the San Francisco Peninsula, with the Pacific Ocean to the west, San Francisco Bay to the east, and the Golden Gate to the north.

San Francisco DUISan Francisco is a popular international tourist destination renowned for its steep rolling hills, an eclectic mix of Victorian and modern architecture, and famous landmarks, including the Golden Gate Bridge, Alcatraz Island, the cable cars, Coit Tower, and Chinatown. The city is also known for its diverse, cosmopolitan population, including a large and long-established LGBT community. While the climate includes chilly summer fog, the winters are mild.

San Francisco's shoreline has grown beyond its natural limits. Entire neighborhoods such as the Marina and Hunters Point, as well as large sections of the Embarcadero sit on areas of landfill. Treasure Island was constructed from material dredged from the bay as well as material resulting from tunneling through Yerba Buena Island during the construction of the Bay Bridge. Such land tends to be unstable during earthquakes; the resultant liquefaction causes extensive damage to property built upon it, as was evidenced in the Marina district during the 1989 Loma Prieta Earthquake.
