About this map

Valle de San Jose and the surrounding heights of Alameda County appear here during the early 1950s, defined by the infrastructure of water and rail transport. The Hetch Hetchy Aqueduct cuts through the terrain, a critical piece of regional utility work that parallels the drainage of La Costa Creek. Near the northern border, the Arroyo Del Valle Sanatorium stands as a distinct institutional landmark near the Arroyo Valle.

The landscape is marked by steep ridges such as Wauhab Ridge and Apperson Ridge, which frame the agricultural and ranching corridors of the Sunol Valley. Evidence of historical land divisions remains visible through the marked Grant Boundary, while the Western Pacific railroad tracks and the intersection at Scotts Corner highlight the area's role as a transit waypoint between Livermore and the San Francisco Bay area.
