Pittsburg is a city in Contra Costa County, California, United States. It is an industrial suburb located on the southern shore of the Suisun Bay in the East Bay region of the San Francisco Bay Area, and is part of the Sacramento–San Joaquin River Delta area. The population was 76,416 at the 2020 United States Census.


In 1849, Colonel Jonathan D. Stevenson (from New York) bought the Rancho Los Medanos land grant, and laid out a town he called New York of the Pacific. By 1850, this venture failed. With the discovery of coal in the nearby town of Nortonville, California, the place became a port for coaling, and adopted the name Black Diamond, after the mining firm that built the Black Diamond Coal Mining Railroad from there to Nortonville. Because of the industrial potential of the site, a name change to Pittsburg was proposed in 1909.

Pittsburg, originally settled in 1839, was called first "New York Landing", then "Black Diamond", before citizens voted on "Pittsburg" on February 11, 1911. The name was selected to honor Pittsburgh, Pennsylvania, as the two cities' shared a common steel and mining industrial heritage. However, from 1891 to July 1911, Pittsburgh, PA was officially known as "Pittsburg", following a country-wide standardization of geographical names by the United States Board on Geographic Names. Hence, in February 1911, when Pittsburg, CA adopted it name, the 'h' was absent from its namesake city. Five months later, after an appeals process lasting almost two decades, Pittsburgh, Pennsylvania won a rare reversal and the 'h' was restored to the city's official name, which persists to this day, resulting in the spelling difference.

The original town site fronts on the Sacramento/San Joaquin River Delta, reflecting its origins as a deep water channel river port. (As of January 1, 2007, state legislation [Assembly Bill 2324] enabled the city to manage its own riverfront for commercial development and subsequent port operations). Since the early 1900s, the city has grown inland to the south, then spread east and west along State Route 4, now a freeway carrying resident commuters to jobs in the San Francisco Bay-Oakland Region. In the process, the former town of Cornwall, California was absorbed. The city has enjoyed continued residential redevelopment growth near its northern boundary, as well as ongoing construction of major subdivisions in the southwest hills, including San Marco Villas. As of the 2000 census, the city had a total population of 56,769.

Camp Stoneman, located in the area, was a major staging area for the United States Army during World War II and the Korean War.

The post office first opened in 1868 as Black Diamond, and changed its name with the town's in 1911.

During the early 1900s, many Sicilian fishermen from Isola delle Femmine near Palermo settled in what will be Pittsburg.


  • 1954 - Camp Stoneman was officially deactivated by the Army.
  • 1984 - United States Steel closes its Steel mill in the city laying off over 400.
  • 1987 - On the night of a city council meeting that approved the funds to restore the former Railroad Depot, the Pittsburg Railroad Depot burned down.
  • 2011 - Pittsburg is recognized as one of the most diverse suburban cities in the San Francisco Bay Area, the state of California and the United States.
  • 2012 - The original Brenden Theater Corporation theater closed after 22 years, only to reopen in August of that year as Maya Cinemas.
  • 2016 - The city moves to install surveillance cameras along its portion of California State Route 4, in response to a series of 20 freeway shootings in the area that had taken the lives of six people, and injured 11, in the past year


The city of Pittsburg is located 37 miles northeast from San Francisco, 29 miles northeast from Oakland, California, 60 miles north of San Jose and 65 miles south of Sacramento, California. Pittsburg shares a border with the unincorporated community of Bay Point, California to the west, the city of Concord, California to the southwest and Antioch, California to the east. The Suisun Bay is directly north of the city and connects the San Francisco Bay to the Sacramento and San Joaquin rivers.


Pittsburg experiences a hot summer Mediterranean climate (Köppen climate classification Csa) bordering on the Semi-arid climate because of the Mt. Diablo rain shadow in East Contra Costa County.

Redevelopment projects

  • The city is currently in the process of redeveloping the older downtown. In November 2010 The Railroad Book Depot opened. The bookstore is owned and operated by the non-profit Pittsburg Arts & Community Foundation.
  • A new Marina Master Plan is under development along Pittsburg's waterfront which includes a pedestrian promenade with subsequent commercial construction and development planned.
  • An extension of the existing Bay Area Rapid Transit District (BART) rapid transit system, which includes a Pittsburg BART station at Railroad Avenue.
  • A Civic Center Master Plan by the city will promote transit-oriented and mixed-use development to coincide with the construction of the new BART station adjacent to the current Civic Center.
  • The Black Diamond Project will provide services to residents on the north side.

Sports and recreation

The Pittsburg Delta View Golf Course had a back nine originally built in 1947, and a front nine completed in 1991. It closed in March 2018 due to financial difficulty and legal costs stemming from a slip and fall lawsuit. The city had considered keeping the course open, but after debate in May 2018, it was decided to use the land for other economic opportunities.

The Pittsburg Diamonds, an independent professional baseball team, began play as a member of the Pacific Association of Professional Baseball Clubs in 2014. The team played its home games in City Park Field #1 until going on hiatus for 2019 and 2020. It remains to be seen if the team will resume play in 2021.

Bombardier Rail Car Facility

On June 15, 2019, the East Bay Times reported that the Canadian company, Bombardier, Inc. is moving into a former warehouse in Pittsburg, where it will produce train cars destined for its Pacific Coast customers. Bombardier will lease 122,750 square feet (11,404 m2) of the building, while Hitachi Corp., the owner, will retain about 67,000 square feet (6,200 m2). Early in 2019, the Bay Area Rapid Transit (BART) System announced that it will replace its existing fleet of 669 cars with 775 cars of a new design, and has recently been negotiating to buy an additional 425 cars.

Bombardier plans to inaugurate the Pittsburg facility in September, 2019, with an initial workforce of 50, working on cars for the new BART contract, and growing to about 150 within five years.

Bombardier is one of the most active suppliers of train cars, and officials believe that the Pittsburg will substantially improve its competitive position. In the U.S., much of the funding for this equipment is supplied by the Federal Government, which requires that a large part of the work be performed in the U.S. Bombardier's only U.S. production facility is in Plattsburgh, N. Y.

The company also has a number of other important West Coast contracts, including:

  • Maintain the Air Train System at San Francisco International Airport (SFO);
  • supply the rail fleet for the Los Angeles Metrolink System;
  • supply Coast and Sprinter train cars for San Diego's North County Transit District;
  • initial design for automated people mover system at Los Angeles International Airport (LAX).


Pittsburg is home to Los Medanos College, a two-year community college that is part of the Contra Costa Community College District. The college's name is derived from that of Rancho Los Medanos, one of the land grants made by the Mexican Government during its sovereignty over California from 1821 to 1846; Los Medanos, loosely translated from Spanish, means The Sand Dunes. Construction on Los Medanos College was completed in 1974.
