Brentwood is a city in Contra Costa County, California, United States. It is located in the East Bay region of the San Francisco Bay Area. The population is 66,854 as of 2022, an increase of 287% from 23,302 at the 2000 census. The community is still known throughout the Bay Area for its agricultural products - primarily its cherries, corn and peaches. Due to urban sprawl many of the old farms and orchards have been replaced by suburban developments since 1990. Brentwood is increasingly residential, with the rate of population growth in the triple digits during the 1990s and 69% from 2000 through 2010. The city broke ground for a new civic center in November, 2009. The Mission-style architectural inspiration for City Hall, the main building, was the 1910 Brentwood Hotel. The $60 million project, completed in May 2012, includes the 58,000-square-foot City Hall and state-of-the-art City Council Chambers. The Streets of Brentwood, an outdoor lifestyle retail center, opened in Brentwood in 2008. It received a Leadership in Energy and Environmental Design silver certification for amenities such as green roofs, biosales, permeable paving and infiltration planters. The Brentwood water tower perhaps symbolizes the city's transition from a rural farm community to a modern bedroom community. This landmark on Walnut Boulevard, across the street from the Brentwood Park and Ride lot, is the tallest structure in the city. It no longer used for its original purpose, but now serves as a cell phone tower.


Brentwood was originally laid out on land donated from property owned by John Marsh, an East Contra Costa County pioneer who acquired Rancho Los Méganos, the land grant that Brentwood is built upon, in 1837. Brentwood was named after Marsh's ancestral home, the town of Brentwood in the County of Essex, England. The city broke ground for a new civic center in November, 2009.

City departments began moving into the new facility in October 2011, and the former city hall was demolished during November 2011. During the 1990s, many types of retail stores were built along the Brentwood/Antioch border on Lone Tree Way, on both sides of SR 4 B, about 3.5 miles (5.6 km) from downtown Brentwood. The Streets of Brent Wood, an outdoor lifestyle retail center, opened in 2008. The Brentwood water tower perhaps symbolizes the city's transition from a rural farm community to a modern bedroom community.

Indigenous History

The Julpun were Native Americans who were a part of the Bay Miwok tribes who spoke the same language. The Julpun believed that everything in the world had a life or spirit and were very in tune with the nature around them. They set things as sacred where they would pray at as part of their religious beliefs, they ended up coining Mt. Diablo, or as they call it Supremenenu, as the birthplace of the world. In present time the Julpun tribe have more or less settled around the Bay Area. They (the Julpun) are working with the National Park Service, where they united under one federally recognized tribe called the Federated Indians of Graton Rancheria. They weren't mainly concentrated but spread out from the San Joaquin River to the bottom part of Marsh Creek which is now the southern part of Brentwood. They may have went back to their territory and ended up working under John Marsh on the land where their home once was. They are now living in specific groups, while others are living in society where they are preserving their native culture even though they may be away from their tribes. Back then the Julpuns were never reached out too by ethnographers or linguists when the Jul puns still retained their language, the BayMiwok. Back in 1806-1808 few of the Jul Pun migrated over to Mission San Jose with about 100 or so went by 1813. Later on Milliken listed down that about 141 Julpun members were baptized by 1819.
