Concord is located at 37°58′41″N 122°01′52″W / 37.97806°N 122.03111°W / 37.97806; -122.03111.[3] In terms of travelling distance on the ground, 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.[5]

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 close proximity to public transportation and the vibrant area surrounding the park. Despite this, some crime and homelessness remain issues in the downtown area.[6][7]

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. Though it shares no border with Concord, Martinez (the county seat) is located almost immediately adjacent to Concord on the northwest.


Official data from the National Weather Service cooperative station in Concord shows average January temperatures are a maximum of 57.2°F and a minimum of 41.6°F. Average July temperatures are a maximum of 87.8°F and a minimum of 58.2°F. There are an average of 45.0 days with highs of 90°F (32°C) or higher and 3.8 days with lows of 32°F (0°C) or lower. The highest recorded temperature was 110°F on July 23, 2006. The lowest record temperature was 24°F on December 23, 1998.

Average annual precipitation is 18.31 inches, falling on an average of 57 days annually. The wettest year was 1995 with 26.62 inches and driest year was 2007 with 10.57 inches. The most rainfall in one month was 11.79 inches in December 2005, which included the 24-hour maximum rainfall of 3.95 inches on December 31.[8]


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. In 1772 Spanish explorers began to cross the area, but did not settle here. 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 as a result of most residents of Pacheco relocating to Concord to avoid the devastation of fire and flood which crippled Pacheco's formerly booming economy. Concord was incorporated on February 5, 1905.

The area around Concord in the surrounding Ygnacio and Clayton Valleys was a large agricultural area. Crops that were grown included grapes, walnuts, wheat, hay, and even tomatoes. The area to the east (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.[9]

Port Chicago disaster

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 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.[10]

Sunvalley Mall plane crash

On the evening of December 23, 1985, two days before Christmas, a twin-engine Beechcraft Baron, executed a missed instrument approach procedure from an approach to runway 19R of Buchanan Airport. The airport had been closed a few hours earlier due to thick fog. F.A.A. regulations require a "missed approach" be declared if the pilot cannot visually see the runway from .25 miles (about .40 kilometers) from the end of the runway in instrument conditions (when the pilot cannot see the ground). The pilot, a student flying with an instructor, continued the approach a few hundred feet over the runway in the hope of finding a hole in the fog (It is common to find the fog a little thinner farther from the water). After failing to see the runway he began the missed approach, which included a left turn over what would have been empty ground had it been done at the proper place. However he was about a mile farther down the runway and the turn now carried him into the Sunvalley Mall. The plane struck the roof of the building killing the pilot and two passengers and seriously injuring 84 Christmas shoppers in the crowded mall below, mainly by spraying them with burning fuel. Four of the victims on the ground later died from their injuries. The accident brought increased local opposition to the airport, and caused Pacific Southwest Airlines to delay scheduled passenger service that had been planned for the new year.

Naval Weapons Station

Aerial view of the Naval Weapons Station

To the north of the city of Concord is the Concord Naval Weapons Station, which was established in 1942. The station functioned as a World War II armament storage depot, supplying ships at Port Chicago. The Concord NWS supported war efforts during the Vietnam War and through the end of the Gulf War, processing and shipping out thousands of tons of materiel to Southeast Asia and the Middle East.[19]

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)).[20] Because of changes in military operations, parts of the Inland Area began to be mothballed and by 1999, the station had only a minimal contingent of military personnel. In 2007 the U.S. Federal Government announced that the inland portion of the Naval station will be closed. The Tidal area of the base is not scheduled for closure.[19] 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 will continue to do so. Any plan for reuse is subject to approval by the Navy.[20][21]


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. 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.
