Concord is the largest city in Contra Costa County , California. At the 2010 census, the town had a population of 122,067, making it the 8th largest city in the San Francisco Bay Area. Founded in 1869 by Salvio Pacheco as the community of Todos Santos, Concord changed its name within months. The city is a major regional suburb of East Bay in the San Francisco Bay Area, 29 miles east of San Francisco.
It’s 29 miles northeast of San Francisco, 22 miles northeast of Oakland, 65 miles southwest of Sacramento, and 51 miles north of San Jose. According to the United States Census Bureau, the city has a total area of 30.5 square miles of land.
The focal point of downtown Concord is Todo Santos Plaza, which encompasses the entire city block and is known for its farmers ‘ market, free summer concerts and a large number of restaurants in the area. To the north and east of downtown is the old residential area of Concord, with many homes dating back to the pre-World War II period. In the far north of the town there is a predominantly industrial area dominated by the Tesoro Golden Eagle Refinery.
The valleys north of Mount Diablo were inhabited by the people of Miwok, who hunted elk and fished in the numerous streams flowing from the mountain to the Bay of San Francisco. Spanish explorers began to cross the area in 1772, but did not settle there. In 1834, the Mexican land grant to Rancho Monte del Diablo at the base of Mount Diablo was granted to Salvio Pacheco (who is named after the nearby town of Pacheco).
Concord was founded under the name Todos Santos (‘all saints’) on the initiative of Pacheco in 1869. The name still bears the central city square and the park between Willow Pass Road and Salvio Street. It gained prominence in the 19th century, when most of Pacheco ‘s residents moved to Concord to avoid the devastation of fire and floods that crippled Pacheco’s formerly booming economy. Concord was incorporated on 5 February 1905.
The area around Concord in the surrounding valleys of Ygnacio and Clayton was a large agricultural area. Crops that were grown included grapes, nuts, almonds, wheat, hay and even tomatoes. The area to the east (now the site of the Concord Naval Weapons Station) was home to a few huge wheat ranches over 5,000 acres (20 km2) and was almost a sea of wheat all the way to the marshes bordering the Suisun Bay. During the Prohibition, many vineyards were removed and replaced by walnut orchards. The town of Cowell, now incorporated into Concord, has produced cement.
