1947 Map of Walnut Creek

About this map

Concord and Walnut Creek appear as emerging hubs in this late-1940s landscape, where orchards and open valleys are beginning to meet postwar suburban development. The transportation network is anchored by the Sacramento Northern and Southern Pacific railroads, alongside the heavy industrial corridor of the Arnold Industrial Highway. Local history is visible in the distribution of family-named landmarks and institutions, such as the Fernando Adobe and the Japanese Institute (Aban'd), reflecting the area's diverse heritage before mid-century expansion. Significant water infrastructure like the Contra Costa Canal and Mokelumne Aqueduct cuts through the terrain, supporting the transition from agricultural tracts near Pacheco to the growing residential footprints of Saranap and Lafayette. The presence of Buchanan Field and the Naval Reservation highlights the strategic and logistical importance of this Contra Costa region during the era.
