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.[9]


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.[10] By 1850, this venture failed.[10] With the discovery of coal in the nearby town of Nortonville, the place became a port for coaling, and adopted the name Black Diamond, after the mining firm[10] that built the Black Diamond Coal Mining Railroad from there to Nortonville.[11] Because of the industrial potential of the site, a name change to Pittsburg was proposed in 1909.[10]

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.[12] This rechristening came at a time when the name of Pittsburgh, Pennsylvania was more commonly spelled without the "h".[13]

Columbia Steel plant on Loveridge Road in Pittsburg, was established in 1910

In 1910, Columbia Steel opened its California steel plant in Pittsburg with one foundry and a crew of 60 employees. It made steel castings for the dredging, lumber and shipping industries. In 1930, Columbia became a subsidiary of U.S. Steel Company. The plant continued to grow until the early 1950s, reaching a peak staff of 5,200 employees when the markets for its products crashed. The parent company (by 1986, renamed as USS Company) had merged with Korean Pohang Iron and Steel Company. Together they invested $450 million turning the Pittsburg plant into a modern flat-products mill, renamed as USS-Posco. As of 1999, the facility employed 970 workers and shipped over 1.6 million U.S. tons per year of steel to over 175 customers in the Western U. S., Mexico, Canada and the Pacific Rim.[14]

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. As of the 2000 census, the city had a total population of 56,769.[15]

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.[10]


The city has an extensive history of coal mining and industrial development since the late 1800s, with USS-POSCO Industries (a joint venture between US Steel and POSCO of South Korea) and Corteva (formerly, the Dow Chemical Company) maintaining substantial plants in Pittsburg.[14]

Bombardier Rail Car Facility[edit]

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.[17]

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.[17]

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.[17]

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).[17]


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.[18][19]


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.[20]

Pittsburg/Bay Point BART Station

The city has two BART stations, the Pittsburg/Bay Point Station located on Bailey Road and Highway 4 near Bay Point and the Pittsburg Center Station located on Railroad Avenue and Highway 4.[22] Tri Delta Transit provides bus service in the area. California State Route 4 bisects the city from west to east.


Pittsburg is home to Los Medanos College,[23] 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.[24][25]

Pittsburg is served by three School Districts: Pittsburg Unified School District, Mt. Diablo Unified School District, and Antioch Unified School District.

Pittsburg has two public high schools, one a continuation school:[26]

Public libraries[edit]

Redevelopment projects[edit]

  • 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.[28]
  • A new Marina Master Plan is under development along Pittsburg's waterfront which includes a pedestrian promenade with subsequent commercial construction and development planned.[29]

Sports and recreation[edit]

The Pittsburg Delta View Golf Course had a back nine originally built in 1947, and a front nine completed in 1991.[30] 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.[31]

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.[32]
