LAW AND GOVERNMENT

San Francisco—officially known as the City and County of San Francisco—is a consolidated city-county, a status it has held since the 1856 secession of what is now San Mateo County. It is the only such consolidation in California. The mayor is also the county executive, and the county Board of Supervisors acts as the city council. Under the city charter, the government of San Francisco is constituted of two co-equal branches. The executive branch is headed by the mayor and includes other citywide elected and appointed officials as well as the civil service. The 11-member Board of Supervisors, the legislative branch, is headed by a president and is responsible for passing laws and budgets, though San Franciscans also make use of direct ballot initiatives to pass legislation.
The members of the Board of Supervisors are elected as representatives of specific districts within the city. Upon the death or resignation of mayor, the President of the Board of Supervisors becomes acting mayor until the full Board elects an interim replacement for the remainder of the term. In 1978, Dianne Feinstein assumed the office following the assassination of George Moscone and was later selected by the Board to finish the term. In 2011, Edwin M. Lee was selected by the Board to finish the term of Gavin Newsom, who resigned to take office as Lieutenant Governor of California.
Because of its unique city-county status, local government exercises jurisdiction over property that would otherwise be located outside of its corporation limit. San Francisco International Airport, though located in San Mateo County, is owned and operated by the City and County of San Francisco. San Francisco also has a county jail complex located in San Mateo County, in an unincorporated area adjacent to San Bruno. San Francisco was also granted a perpetual leasehold over theHetch Hetchy Valley and watershed in Yosemite National Park by the Raker Act in 1913.
San Francisco serves as the regional hub for many arms of the federal bureaucracy, including the U.S. Court of Appeals, the Federal Reserve Bank, and the U.S. Mint. Until decommissioning in the early 1990s, the city had major military installations at the Presidio,Treasure Island, and Hunters Point—a legacy still reflected in the annual celebration of Fleet Week. The State of California uses San Francisco as the home of the state supreme court and other state agencies. Foreign governments maintain more than seventy consulates in San Francisco.
The municipal budget for fiscal year 2011–12 was $6.83 billion. The city employs around 27,000 workers.
