Editing Brentwood, California (section)

==Geography==
[[File:Northpeak.jpg|thumb|Photo of Mount Diablo, showing Brentwood behind the mountain and to the right.]]

As is common with many [[East Bay (San Francisco Bay Area)|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 {{convert|14.81|sqmi|km2|1|abbr=on}}, of which {{convert|14.79|sqmi|km2|1|abbr=on}} is land and {{convert|0.02|sqmi|km2|2|abbr=on}} 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 climate]]s (''Bsh''). Like most of East Contra Costa County, Brentwood lies in the rain shadow of [[Mt. Diablo]]<ref>{{cite web |url=http://www.co.contra-costa.ca.us/depart/cd/water/hcp/archive/downloads/wetland_report/Ch03_Hydrogeomorphic_Setting_10_14_04.pdf |archive-url=https://web.archive.org/web/20081114124040/http://www.co.contra-costa.ca.us/depart/cd/water/hcp/archive/downloads/wetland_report/Ch03_Hydrogeomorphic_Setting_10_14_04.pdf |archive-date=Nov 14, 2008 |title=Draft Aquatic Resources Inventory, Classification, and Function for East Contra Costa County HCP/NCCP Inventory Area (Partial) |id=J&S 01-478 |date=Oct 2004}}</ref> 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.<ref>{{cite book|url=https://books.google.com/books?id=USbNknthNW0C&pg=PA32|title=Walking the Flatlands: The Rural Landscape of the Lower Sacramento Valley|first=Mike|last=Madison|date=January 17, 2017|publisher=Heyday|access-date=January 17, 2017|via=Google Books|isbn=9781890771843}}</ref>
