Livermore and Pleasanton anchor this mid-century portrait of the Amador Valley, a landscape transitioning from rural ranching to suburban expansion. The valley floor is marked by extensive extractive industry, including numerous Gravel Pits concentrated near East Pleasanton and along the banks of Arroyo Valle. Vital transportation corridors defined by the Southern Pacific and Western Pacific railroads bisect the valley, supporting a local economy that includes the Santa Rita Rehabilitation Center Annex and the Livermore Municipal Airport.
