1953 Map of La Costa Valley

About this map

The Valle de San Jose and La Costa Valley are defined by an intricate network of ridgelines and water infrastructure in the early 1950s. Infrastructure developments like the Hetch Hetchy Aqueduct and the Vallecitos Pipe Line cut across the landscape, illustrating the region's vital role in California's water management during this era of post-war expansion. While the high ground is dominated by Maguire Peaks and the steep terrain of Wauhab Ridge and Apperso n Ridge, the lowlands contain pockets of institutional activity including the US Veterans Administration facility and the Arroyo Del Valle Sanatorium.
