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 -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, bioswales, 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. 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 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 , of which is land and 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. 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. The City of Brentwood operates under the City Manager form of government. Effective January 17, 2015, this position will be held by Gustavo "Gus" Vina. Vina was formerly city manager of Encinitas, California. Under policy direction of the City Council, the City Manager serves as the Chief Administrative Officer of the City; assumes full responsibility for planning, administering, directing, overseeing, and evaluating the activities and operations of all City departments.
