1947 Map of San Jose

About this map

The Santa Clara Valley serves as a major hub of settlement and transit in this post-war survey, centered on the growing footprints of San Jose and Santa Clara. To the east, the Diablo Range rises steeply, marked by landmarks like Mount Hamilton and Mount Isabel, creating a natural barrier between the coastal valley and the vast interior agricultural lands of the San Joaquin. The landscape is defined by its water infrastructure, notably the Hetch Hetchy Aqueduct and numerous reservoirs like Don Pedro Reservoir and Melones Reservoir that feed the valley's development.
