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 from Jose Noriega.

Marsh was one of the wealthiest men in California and was instrumental in its becoming independent from Mexico and part of the United States.

This landmark on Walnut Boulevard, across the street from the Brentwood Park and Ride lot, is the tallest structure in the city.

The city is bordered on three sides by the Contra Costa County Agricultural Core which consists of 11,000 acres of preserved and still actively productive farm land.

During the 1990s, many retail stores were built along the Brentwood/Antioch border on Lone Tree Way, on both sides of SR 4, about 3.5 miles (5.6 km) from downtown Brentwood.

The center received a Leadership in Energy and Environmental Design silver certification for amenities such as green roofs, biosales, permeable paving and infiltration planters.

They set things as sacred where they would pray at as part of their religious beliefs, they ended up coining Mt.

As time went on, Mission San Jose converted from religious beliefs and values to secular institutions where the Julpun members ended up leaving in 1836 back to their original territory.

However, due to Mission San Jose revoking the spiritual possession it once had, the Julpuns may have gone back to their territory and ended up working under John Marsh on the land where their home once was.

[16] As is common with many East Bay towns in Contra Costa County, Mount Diablo is clearly seen from Brentwood.

The landscape on the west is marked by rolling hills, non-native grasses, oak trees, fruit orchards, and vineyards, with a number of public golf courses.

The wet season is generally October through April, though there may be a day or two of light rainfall in June or September.

Summer heat is often moderated by the Delta breeze, especially in the late afternoon, causing temperatures to cool rapidly.

[21] Brentwood established its own City Police Department in 1948, when it was primarily a small agricultural community.

Resources are shared with the communities of Oakley, Bethel Island, Knightsen, Byron and Discovery Bay.

The Delta Patrol Station has occupied a 1920s era building for over four decades, and has been looking for a larger facility in East County to serve the growing population for faster response in unincorporated Contra Costa County areas (e.g., Byron, Discovery Bay and Knightsen).

Heritage High School includes a full range of Advanced Placement courses and the highest Academic Performance Index (California public schools)(API) score in the area, stellar performing arts programs, and championship athletic teams.

The 2.38 kW photovoltaic project installed at Heritage High School is designed to demonstrate the benefits and opportunities created by renewable energy technology and provide a powerful learning tool for both students and the community.

[29] The Brentwood Center acquired property in the southwest part of the city, where it plans built a new 18 acres (7.3 ha) campus that opened in 2021.

[30][31] The temporary Brentwood branch of the Contra Costa County Library, located at 104 Oak Street, across from the Civic Center and City Park, was razed early in 2017, along with two other city-owned buildings at 118 and 120 Oak Street to be replaced by the long-awaited new Brentwood branch library.

It also offers a wide variety of media, including DVDs, CDs, and audiobooks, as well as a large print collection.

Local wineries including Bloomfield, Tamayo, and Hannah Nicole have gained in sales and prestige after winning numerous medals in recent years at the San Francisco Chronicle Wine Competition and the California State Fair.

The boom stalled in 2009, paralleling the economic crisis that affected all of California, but successful new home subdivisions, including a gated community (Carmel Estates), appeared again in 2010.

In 2013, Brentwood's economy displayed renewed economic vigor with substantial new activity in residential and commercial/retail construction.

No freeways served Brentwood directly until February 2008, when the John Marsh Heritage Highway (also known as the California State Route 4 Bypass or Bypass Road, now California State Route 4) was built to connect the western side of Brentwood directly with Antioch.

To the southeast of Brentwood, County Route J4, known as the Byron Highway, connects to Tracy and the San Joaquin Valley.

Tri Delta Transit Route 300X operates roughly 30-minute express bus service between Brentwood Park & Ride and Antioch BART station Monday through Friday, several times per day.

[41] Tri Delta Transit Route 391 provides weekday and weekend local service between Brentwood Park & Ride and Pittsburgh Center Station, with stops at Antioch BART and Los Medanos College.

Brentwood was selected for a variety of reasons, including the fact that it offers the community its Wellness Policy, a community-wide aspirational goal which promotes physical activity and education as the benefits of living a healthy lifestyle.
