About this map

Brentwood and Oakley serve as the primary hubs in this late-1970s landscape, where a sophisticated network of water infrastructure supports the agricultural and residential development of eastern Contra Costa County. The Contra Costa Canal and Mokelumne Aqueduct cut through the terrain, highlighting the area's role in California's water management system. To the south, the Marsh Creek Reservoir and the Briones Valley provide a distinct contrast to the grid-patterned orchards and fields of the Los Meganos grant.

Local history is preserved in the detailed layout of neighborhood schools like Liberty Union High Sch and Edna Hill Sch, and the presence of the Union Cem near Kellogg. Traces of the region's ranching and rail heritage are visible in the corridors of the Southern Pacific and Atchison Topeka and Santa Fe railroads, which once defined the movement of goods between the Dutch Slough and the inland valleys.
