1959 Map of Walnut Creek

About this map

Concord and Walnut Creek appear during a period of significant suburban expansion in Contra Costa County. The landscape is defined by the intersection of major transit and utility corridors, including the Southern Pacific and Sacramento Northern railroads alongside the Contra Costa Canal and Mokelumne Aqueduct. This survey captures the transition from agricultural roots—visible in the Clayton Valley and the smaller settlements of Meinert and Bancroft—to the modern residential grids of Pleasant Hill and Lafayette. Significant institutional footprints are established at Diablo Valley College and the Naval Weapons Station Concord. The terrain is shaped by Lime Ridge and Shell Ridge, while the Lafayette Reservoir stands as a prominent engineered landmark amidst the growing communities.
