Concord (/ˈkɒŋkərd/ KON-kerd)[10] is the largest city in Contra Costa County, California. According to an estimate completed by the United States Census Bureau, the city had a population of 129,295 in 2019,[11] making it the eighth largest city in the San Francisco Bay Area.[12][13] Founded in 1869 as Todos Santos by Don Salvio Pacheco II, a noted Californio ranchero, the name was later changed to Concord. The city is a major regional suburban East Bay center within the San Francisco Bay Area, and is 29 miles (47 kilometers) east of San Francisco.

The United States Census Bureau defines an urban area in the East Bay which is separated from the San Francisco–Oakland urban area and with Concord as the principal city: the Concord–Walnut Creek, CA urban area had a population of 538,583 as of the 2020 census, making it the 80th largest in the United States.[8]


Concord was founded as "Todos Santos" in 1869 by Don Salvio Pacheco, a noted Californio ranchero.

The valleys north of Mount Diablo were inhabited by the Miwok people, who hunted elk and fished in the numerous streams flowing from the mountain into the San Francisco Bay. It is important to note Miwok and other indigenous people still live within city limits. In 1772, Spanish explorers began to cross the area but did not settle there. In 1834, the Mexican land grant Rancho Monte del Diablo at the base of Mount Diablo was granted to Salvio Pacheco (for whom the nearby town of Pacheco is named).

Concord was founded under the name of Todos Santos ("all saints"; a name still borne by the central city plaza and park between Willow Pass Road and Salvio Street), on the initiative of Pacheco in 1869. It achieved prominence in the 19th century, when most residents of Pacheco relocated to Concord to avoid the devastation of fire and flood which crippled Pacheco's formerly booming economy. Concord was incorporated on February 5, 1905.[14]

The area around Concord in the surrounding Ygnacio and Clayton Valleys was a large agricultural area. Crops that were grown included grapes, walnuts, almonds, wheat, hay, and even tomatoes. The area to the east (now the site of the Concord Naval Weapons Station) was the site of a few enormous wheat ranches over 5,000 acres (20 km2), and was almost a sea of wheat all the way to the marshes bordering Suisun Bay. During Prohibition, many vineyards were removed and replaced with walnut orchards. The town of Cowell, now incorporated into Concord, produced cement.

The first Concord post office opened in 1872.[15]

Port Chicago disaster[edit]

The munitions on board a Navy cargo ship exploded while being loaded during World War II, resulting in the largest number of casualties among African Americans in any one incident during that war. On the evening of July 17, 1944, a massive explosion instantly killed 320 sailors, merchant seamen, and civilians working at the pier. The blast was felt 30 miles (48 km) away. A subsequent refusal by 258 black sailors to load any more ammunition was the beginning of the Navy's largest-ever mutiny trial, in which 50 men were found guilty. Future Supreme Court Justice Thurgood Marshall sat in on most of the proceedings and declared that he saw a prejudiced court.[16]


Todos Santos Plaza is downtown.

Concord is located at 37°58′41″N 122°01′52″W / 37.97806°N 122.03111°W / 37.97806; -122.03111.[10] It is 29 miles (47 km) northeast of San Francisco, 22 miles (35 km) northeast from Oakland, 65 miles (105 km) southwest of Sacramento, and 51 miles (82 km) north of San Jose.[17]

According to the United States Census Bureau, the city has a total area of 30.5 square miles (79 km2), all of it land.

The focal point of downtown Concord is Todos Santos Plaza, which encompasses an entire city block and is known for its farmers market, free summer concerts, and large number of surrounding restaurants. Much of the area immediately around downtown has recently been redeveloped, with new high-density apartment and condominium projects to take advantage of the proximity to public transportation and to the area surrounding the park. Despite this, some crime and homelessness remain issues in the downtown area.[18][19]

To the north and east of downtown is the older residential area of Concord, with many homes dating back to before World War II. In the far northern edge of town is a primarily industrial area, dominated by the Tesoro Golden Eagle Refinery (which is actually not located within city limits). The southeastern area of the city, centered along Clayton Road, is primarily residential and was mostly developed in the 1960s and 1970s. In the southwest area of the city is the primarily Latino neighborhood known as Four Corners, centered around the intersection of Monument Boulevard and Oak Grove Road.

Concord is bordered on the west by Pleasant Hill and the unincorporated community of Pacheco, on the south by Walnut Creek, on the southeast by Clayton, on the northeast by Pittsburg and the unincorporated community of Bay Point, and on the north by the unincorporated community of Clyde. Although it shares no border with Concord, Martinez (the county seat) is located almost immediately adjacent to Concord on the northwest. The North Concord BART station is also known as Martinez BART.

Naval Weapons Station[edit]

Aerial view of the Concord Naval Weapons Station

To the north of the city of Concord is the Concord Naval Weapons Station (CNWS), which was established in 1942. The station functioned as a World War II armament storage depot, supplying ships at Port Chicago. The CNWS supported war efforts during the Vietnam War and through the end of the Gulf War, processing and shipping out thousands of tons of material to Southeast Asia and the Middle East.[32]

The station consists of two areas: the inland area (5,170 acres [21 km2]) which is within the Concord city limits, and tidal area (7,630 acres [31 km2]).[33] Because of changes in military operations, parts of the inland area began to be mothballed and by 1999, the CNWS had only a minimal contingent of military personnel. In 2007, the U.S. Federal Government announced that the inland portion of the CNWS will be closed. The tidal area of the base is not scheduled for closure.[32] The tidal area was transferred to the U.S. Army Surface Deployment and Distribution Command (SDDC) and is now known as Military Ocean Terminal Concord (MOTCO).[34][35] The city is working on a reuse plan that may include developing the land while keeping a large portion for open-space and parks projects. The city has had many meetings on this subject and any plan for reuse is subject to approval by the Navy.[33][36]


Until 1995, the city was the eastern terminus of the Concord line of Bay Area Rapid Transit (BART) commuter train system; the line has since been extended eastward to Pittsburg/Bay Point in 1996 and Antioch in 2018. The County Connection provides limited public transportation in the city and to other points in the county. Buses run from the North Concord BART station to Martinez, the county seat.

It is served by JetSuiteX, and previously served by American Eagle, WestAir Commuter Airlines, Pacific Southwest Airlines (PSA) and later by PSA successor USAir with the latter two airlines operating nonstop jet service between the airfield and Los Angeles International Airport (LAX).



The city of Concord is served by the daily newspaper the East Bay Times (formerly the Contra Costa Times) published by Bay Area News Group-East Bay (part of the Media News Group, Denver, Colorado), with offices in Walnut Creek.

Concord and the neighboring cities of Pleasant Hill and Walnut Creek are also served by KKDV FM 92.1. The commercial station brands itself "Diablo Valley's hometown station" and plays a mix of current hits and those from the last few decades.

From 1963 to 1993, Concord had a local radio station, KWUN AM 1480, also known as Contra Costa's K-15.


Concord is served by major television stations broadcasting primarily out of San Francisco, Sacramento, and San Jose. The region's Fox affiliate, KTVU, is based in (and licensed to) Oakland at Jack London Square along with co-owned independent station KICU-TV (licensed to San Jose).

Over-the-air reception is difficult in many parts of the city due to hills on either side of the valley.

The sole Concord-licensed TV station, KTNC, gave up its broadcast frequency as part of the FCC reverse spectrum auction in 2017. It had broadcast on channel 42 from the top of Mount Diablo, but is now available on virtual channel 42 via a subchannel of KCNS channel 39.


Concord is served by the Mount Diablo Unified School District (MDUSD). Among the MDUSD schools is Mt. Diablo High School, opened in 1901 and currently home to four academies, including the Digital Safari Academy, a three-year program involving the integration of multimedia with the core curriculum through integrated, project-based learning.

Beyond MDUSD schools, Clayton Valley Charter High School is also home to several acclaimed academies. Catholic schools De La Salle High School for boys and Carondelet High School for girls are also located here. De La Salle's football team holds the U.S. record winning streak of 151 games, set between 1992 and 2004. During that span, De La Salle won 12 California North Coast sectional championships and was named national champion five different times (once by ESPN, four times by USA Today). In August 2014, a Hollywood film titled When the Game Stands Tall was released with the plot line based on their 151-game winning streak.
