San Joaquin County ( Spanish: San Joaquín, meaning "St. Joachim"), officially the County of San Joaquin is a county in the U.S. state of California. As of the 2010 census, the population was 685,306. The county seat is Stockton.
San Joaquin County comprises the Stockton–Lodi–Tracy metropolitan statistical area within the regional San Jose–San Francisco–Oakland combined statistical area. The county is located in Northern California's Central Valley just east of the very highly populated nine-county San Francisco Bay Area region and is separated from the Bay Area by the Diablo Range of low mountains with its Altamont Pass. One of the smaller counties in area in California, it has a high population density and is growing rapidly due to overflow from the Bay area's need for housing.
- Metropolitan Statistical Area
San Joaquin County was one of the original United States counties of California, created in 1850 at the time of statehood.
The county was named for the San Joaquin River which runs through it. In the early 19th century Lieutenant Gabriel Moraga, commanding an expedition in the lower great California Central Valley, gave the name of San Joaquin (meaning Joachim) to the San Joaquin River, which springs from the southern Sierra Nevada. San Joaquin County is the site of the San Joaquin Valley's first permanent residence.
Between 1843 and 1846, during the era when California was a province of independent Mexico, five Mexican land grants were made in what became San Joaquin County: Campo de los Franceses, Pescadero (Grimes), Pescadero (Pico), Sanjon de los Moquelumnes and Thompson.
It was developed for ranching and agriculture. It attracted more miners and settlers at the time of the California Gold Rush.
Tracy tire fire
On August 7, 1998, a tire fire ignited at S.F. Royster's Tire Disposal just south of Tracy on South MacArthur Drive, near Linne Rd. The tire dump held over 7 million illegally stored tires and was allowed to burn for more than two years before it was extinguished. Allowing the fire to burn was considered to be a better way to avoid groundwater contamination than putting it out. The cleanup cost $16.2 million and wound up contaminating local groundwater anyway.
According to the U.S. Census Bureau, the county has a total area of 1,426 square miles (3,690 km2), of which 1,391 square miles (3,600 km2) is land and 35 square miles (91 km2) (2.5%) is water.
The center of San Joaquin County is near Stockton at about 37°54'N 121°12'W (37.9,-121.2).
