Agricultural legacy and suburban expansion define this 2012 survey of eastern Contra Costa County. Brentwood and Oakley serve as the primary hubs, surrounded by a transition from residential developments to established ranching and farming operations. The landscape is interconnected by a complex network of waterways, including the Contra Costa Canal and the Main Canal, which support a series of named agricultural holdings such as Smith Family Farms, Knoll Organic Farms, and Terada Farms. To the north and west, the terrain rises toward Sand Hill and the Briones Valley, while the eastern portion remains low-lying near Rock Slough. Regional industry is visible through the Brentwood Gas Field and the Dutch Slough Gas Field, while local transit and recreation are represented by the Funny Farm Airport and the waters of Marsh Creek Reservoir.
