About this map

Brentwood and the surrounding Contra Costa County ranch lands are depicted here in the mid-1950s, defined by an intricate network of water management and rail transportation. The landscape is a matrix of large-scale irrigation projects, including the Contra Costa Canal and the Mokelumne Aqueduct, which support the agricultural tracts of Lone Tree Valley and Los Meganos. The settlement patterns follow the established lines of the Atchison Topeka and Santa Fe Railway and the Southern Pacific, connecting hubs like Oakley, Knightsen, and Byron.

A notable local landmark is the John Marsh Historical Marker located near Marsh Creek, signifying the early ranching history of the region. Local community life is anchored by institutions such as Liberty Union HS and rural schoolhouses like Lone Tree Sch. The presence of the Point of Timber Cemetery and various pumping stations highlights the early 20th-century development of this inland delta region as it transitioned from pioneer ranching to intensive irrigated farming.
