The San Leandro Hills descend into a rapidly densifying East Bay corridor, where post-war suburban growth meets the established industrial and transport infrastructure of Hayward. This 1959 survey, updated with 1968 aerial data, shows the expansion of residential tracts across San Lorenzo and Castro Valley, reaching toward the foothills and Cull Canyon. The footprint of major institutions like California State College Hayward and the Alameda Co Juvenile Hall signal the area's increasing importance as an administrative and educational hub for Alameda County.
