# Brentwood, California

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.
Brentwood was settled by Euro-Americans in the late 19th century. 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 Due to urban sprawl, many of the old farms and orchards have been replaced by suburban properties and developments since 1990.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. As of currently, estimates put the population at around 65,350; a 26.5% increase from 2010.

## History

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. His letters extolling the potential for agriculture in California were published in newspapers throughout the East. They resulted in the first wagon trains to California. Marsh encouraged this, and allowed new arrivals to stay on his ranch until they could get settled. Rancho Los Méganos became the terminus of the California Trail. Brentwood was named after Marsh's ancestral home, the town of Brentwood in the County of Essex, England.
Brentwood's first post office was established in 1878. The city incorporated in 1948.
Balfour, Guthrie & Co., a British investment company, purchased the John Marsh ranch in 1910. The company invested heavily in other California agricultural properties as well. In 1910, it built the Brentwood Hotel at Oak Street and Brentwood Boulevard, across from the railroad station. This replaced an earlier hotel on the same site that had burned down in 1903. The hotel was razed in 1967, and replaced by a service station.
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 is no longer used for its original purpose, but now serves as a cell phone tower. City water is stored in large tanks atop hills outside 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 Streets of Brentwood, an outdoor lifestyle retail center, along Sand Creek Rd opened in 2008.
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, a 32,000-square-foot community center, 280-space parking garage and redevelopment of the 1⁄2-acre City Park. The community center also includes arts and crafts rooms as well as studios for dance classes and community exercise programs. The center received a Leadership in Energy and Environmental Design silver certification for amenities such as green roofs, biosales, permeable paving and infiltration planters. City departments began moving into the new facility in October 2011, and the former city hall was demolished during November 2011.

## Indigenous history

Brentwood was home to the Julpuns who settled mainly in the upper corner of the East Bay. The Julpun were Native Americans who were a part of the Bay Miwok tribes who spoke the same language in an area, which is a branch of the Eastern Miwok Language. The Bay Miwok tribes would generally include 50-200 people in each village, where they would build their villages along the creeks since they were filled with fish. 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. Due to this, they would hold the top points of Mt. Diablo to be used for sacred gatherings or religious purposes.
Back then the Julpun were never reached out to by ethnographers or linguists when the Julpun still retained their language, the Bay Miwok. 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. Between 1806 and 1808 few of the Julpun 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 from Mission San Jose. 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. John Marsh ended up acquiring Rancho Los Meganos from Jose Noriega in 1837 which would cover modern Brentwood and back then cover the Julpuns 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.
In present time the Julpun tribe have more or less settled around the Bay Area. Some are 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. 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.

## Geography

As is common with many East Bay towns in Contra Costa County, Mount Diablo is clearly seen from Brentwood. Brentwood is located on the alluvial plain of the Sacramento-San Joaquin Delta. In the picture shown at right, Brentwood lies center right and the city of Antioch, California lies center left. North Peak appears in the foreground between the two cities and largely hides the city of Oakley.
The East Bay Regional Park District is a special San Francisco Bay Area district operating in the East Bay counties of Alameda County and Contra Costa County. East Bay Regional Park District trails and parks are found in Brentwood.
Brentwood has a total area of 14.81 sq mi (38.4 km$^2$), of which 14.79 sq mi (38.3 km$^2$) is land and 0.02 sq mi (0.05 km$^2$) or 0.13% is water. 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.

### Climate

Brentwood borders on the Mediterranean (Csa) and Semi-arid climates (Bsh). Like most of East Contra Costa County, Brentwood lies in the rain shadow of Mt. Diablo and receives less rainfall than many of its neighbors. 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.

### Fire Protection

Fire protection is provided by the East Contra Costa Fire Protection District (ECCFPD), which reports to the Contra Costa County Board of Supervisors. Resources are shared with the communities of Oakley, Bethel Island, Knightsen, Byron and Discovery Bay. It also covers certain unincorporated areas of the county. The fire district is headquartered in the Brentwood City Hall building.

### Public library

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. The Brentwood City Council approved the design for the new 20,000 square feet (1,900 m$^2$) facility in September 2016. The facility was completed in 2018, and serves a population of more than 50,000. The library collection includes materials in both Spanish and English.

## Economy

Agriculture remains important to the local economy, but has declined in relative importance as the city has become more suburban. 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. There is no heavy industry and only a small light industrial area in the northeastern part of the city. Brentwood underwent a strong economic boom from 2000 through 2008. Population expanded from 23,302 in 2000 to about 48,000 in 2006, a higher growth rate than other communities in the Bay Area. Some of the new neighborhoods were centered around two new golf courses, the Shadow Lakes Golf Club and the Deer Valley Golf Club, that were constructed to take advantage of the views of Mt. Diablo. 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. Within an active adult community (Trilogy at the Vineyards), Club Los Meganos opened in 2010 with 34,000 square feet (3,200 m$^2$) of athletic club, pool and cabanas, gourmet studio, spa, tennis courts, and events center. In 2013, Brentwood's economy displayed renewed economic vigor with substantial new activity in residential and commercial/retail construction. Sales offices of new home subdivisions commonly advertise new houses beginning in the $500Ks with the largest homes with many upgrades nearing $1M. The overall improvement in the Bay Area economy and anticipation for the 2015 completion of eBart and highway improvements in East Contra Costa County are playing a part in the revival of strong economic growth in Brentwood. One of the most exciting development opportunities in Brentwood is linked to the two Federal research facilities – Lawrence Livermore National Laboratory and Sandia National Laboratories – that are located 25 minutes south of Brentwood. Brentwood has established close relations with the national labs and is a member of i-GATE, which is a regional partnership designed to promote tech-oriented business growth connected with the labs.

## Transportation
### Highway

Public transportation is very limited, so the principal roads leading into the city are very congested with commuter traffic. 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. State Route 4 passes by the western edge of Brentwood. The freeway portion of SR 4 ends just south of the Balfour Road exit. SR 4 continues as a two-lane highway to its intersection with Marsh Creek Road and the end of Vasco Road, an unnumbered highway that is the principal route to Livermore, Interstate 580, and the Silicon Valley. To the southeast of Brentwood, County Route J4, known as the Byron Highway, connects to Tracy and the San Joaquin Valley.
