Parks Air Force Base and the Naval Auxiliary Air Field anchor the northern landscape of this mid-century survey, reflecting the area's significant military presence. The valley floors are a hub of infrastructure and transit, where the Southern Pacific Railroad and Western Pacific Railroad intersect near Pleasanton and Livermore. This period shows the transition from agrarian roots to suburban development, with the U S Govt Nursery and County Fairgrounds situated alongside emerging residential grids.
