1996 Map of La Costa Valley

USGS Topo · Published 1999

About this map

Vallecitos Nuclear Center stands as a prominent technological landmark within the Valle de San Jose, situated among the ridgelines of southeastern Alameda County in the late 1990s. The landscape is defined by the critical water infrastructure of the Hetch Hetchy Aqueduct, which traverses the terrain near Scotts Corner. The map captures a sophisticated network of drainage systems, including Arroyo de la Laguna and San Antonio Creek, which flow through the protected lands of the Sunol-Bernal Regional Park District and the Sunol Regional Wilderness. Elevated features like Maguire Peaks and the Sunol Ridge provide a topographical framework for the area, where historical land use is marked by a prominent Grant Boundary and resource extraction sites such as the Gravel Pits along the western edge.
