1941 Map of Pleasanton

About this map

The Livermore Valley and surrounding ridges appear here just before the massive post-war suburban shift, defined by a landscape of sprawling ranchos and agricultural settlements. Historical boundaries such as Rancho San Ramon (Norris) and Rancho Santa Rita dominate the northern half, while the Hetch Hetchy Aqueduct cuts through the southern hills, marking a critical piece of California's water infrastructure. The map details the early transit and social hubs of the region, from the Livermore Airport and Rodeo Grounds to the Hacienda Dude Ranch near Pleasanton. At the foot of Mission Peak, the complex at Mission San Jose de Guadalupe serves as a reminder of the area's deep colonial roots. The rail corridors of the Southern Pacific and Western Pacific connect these towns, including Sunol, Irvington, and Livermore, before the modern freeway system reshaped the valley's character.
