[edit] History

The county was formed on March 25, 1853 from a large portion of Contra Costa County and a smaller portion of Santa Clara County.

The Spanish word alameda means "a place where poplar trees grow", a name which originally was given to the Arroyo de la Alameda (Poplar Grove Creek). The willow and sycamore trees along the banks of the river reminded the early explorers of a road lined with trees, also known as an alameda.^{[citation needed]}

The county seat at the time it was formed was located at Alvarado; it was moved to San Leandro in 1856 where the county courthouse was destroyed by the devastating 1868 quake on the Hayward Fault. The county seat was then re-established in the town of Brooklyn from 1872-1875. Brooklyn is now part of Oakland, which has been the county seat since 1873.

Much of what is now considered an intensively urban region, with major cities, was developed as a trolley car suburb of San Francisco in the late 19th and early 20th centuries. The historical progression from native American tribal lands to Spanish, then Mexican ranches, thence to farms, ranches, and orchards, suburbs and eventually cities, is shared with the adjacent Contra Costa County (see that article for an extensive history applicable to this county).

[edit] Government

The county is divided into five different districts. A Supervisor is elected in each district, with an election held every four years. This elected group is known as the Board of Supervisors. Currently, District 1 is represented by Supervisor Scott Haggerty; District 2, Supervisor Gail Steele; District 3, Supervisor Alice Lai-Bitker; District 4, Supervisor Nate Miley; District 5, Supervisor Keith Carson. The Board elects a president who presides at all meetings of the Board and appoints committees to handle work involving the major programs of the county. If the president is absent for a meeting, the vice president shall be responsible. A Board election occurs every two years for these positions. Supervisor Lai-Bitker is serving currently as president; Supervisor Miley is vice president.

Board meetings are open to the public, and occur every Tuesday (with the exception of holidays and board retreats) at 9:00 AM in the County Administration Building in Oakland. Day-to-day administrative operations are handled by the County Administrator. This position is appointed by the Board of Supervisors, currently held by Susan Muranishi.

The county's law enforcement is overseen by an elected Sheriff/Coroner and an elected District Attorney. The Sheriff supervises the deputies of the Alameda County Sheriff's Office, whose primary responsibilities include policing unincorporated areas of the county and cities within the county which contract with the Sheriff's Office for police services; providing security and law enforcement for county buildings including courthouses, the county jail and other county properties; providing support resources, such as a criminalistics laboratory and search and rescue capabilities, to other law enforcement agencies throughout the county; and serving the process of the county's Superior Court system. The District Attorney's office is responsible for prosecuting all criminal violations of the laws of the state of California, the county, or its constituent municipalities, in Superior Court. As of late 2009, the Sheriff is Gregory J. Ahern, who was elected in 2006 to replace Charles C. Plummer, who had served in the post for 20 years. The Interim District Attorney is Nancy E. O'Malley, who was appointed to fill the position of retiring District Attorney Tom Orloff in September 2009. The Sheriff's Office operates two jails, one being Santa Rita Jail located in Dublin.

The Alameda County Fire Department (ACFD) was formed on July 1, 1993 as a dependent special district with the Alameda County Board of Supervisors as its governing body. This consolidation brought together into a single jurisdiction the Castro Valley Fire Department, Eden Fire Department and County Fire Patrol (each a dependent special district under the Board of Supervisors).

The county's Superior Court operates in twelve separate locations throughout the county, with its central Rene C. Davidson Courthouse located in Oakland near Lake Merritt. Most major criminal trials and complex civil cases are heard at this location or in courtrooms within the County Administration Building across the street.

[edit] Events

The annual county fair is held at the Alameda County Fairgrounds in Pleasanton. The fair runs for 3 weekends from June to July. Attractions include horse racing, carnival rides, 4-H exhibits, and live bands.

[edit] Geography

According to the U.S. Census Bureau, the county has a total area of 821 square miles (2,127 km²), of which 738 square miles (1,910 km²) is land and 84 square miles (216 km²) (10.18%) is water.

The San Francisco Bay borders the county on the west, and the City and County of San Francisco, California has a small land border with the city of Alameda due to land filling [1]. The crest of the Berkeley Hills form part of the northeastern boundary, and reach into the center of the county. A coastal plain several miles wide lines the bay; it is home to Oakland and the most populous regions. Livermore Valley lies in the eastern part of the county.

The Hayward Fault, a major branch of the San Andreas Fault to the west, runs through the most populated parts of Alameda County, while the Calaveras Fault runs through the southeastern part of the county.

[edit] Politics

Alameda County is a stronghold of the Democratic Party. It has not voted for a Republican presidential candidate since 1956, when Dwight Eisenhower carried the county. Historically, the county was Republican until the 1958 defeat of William F. Knowland. Even when Ronald Reagan won the national popular vote by an 18.3% margin in 1984, Walter Mondale won Alameda County by a slightly larger margin. In 2004 it voted for John Kerry by a margin of over 50%. Every city and town voted Democratic.^[4] In the House of Representatives, all of the 9th district, parts of the 10th and 11th districts, and most of the 13th district are in the county. All four districts are held by Democrats: Barbara Lee, John Garamendi, Jerry McNerney, and Pete Stark, respectively.

In the State Assembly, parts of the 14th and 15th districts, all of the 16th and 18th districts, and most of the 20th district are in the county. All of its five legislators are Democrats: Nancy Skinner of the 14th district, Sandré Swanson of the 16th district, Mary Hayashi of the 18th district, and Alberto Torrico of the 20th district, and Joan Buchanan of the 15th district. In the State Senate, most of the 9th and 10th districts are in the county and are both represented by Democrats: Loni Hancock and Ellen Corbett, respectively.

According to the California Secretary of State, there are 709,414 registered voters in Alameda County. 401,847 (56.6%) are registered Democrats, 116,864 (16.5%) are registered Republicans, 33,689 (4.8%) are registered to minor political parties, and 157,014 (22.1%) declined to answer. This means Democrats have a 40.1% registration advantage over Republicans. Every city, town, and unincorporated area in Alameda County has more registered Democrats than Republicans.
