About this map

The maritime and industrial character of the north bay is documented in this 1948 survey, overseen by Governor Earl Warren and state engineer Edward Hyatt. The landscape is dominated by the State Penitentiary at San Quentin and the coastal operations of the Tiburon Naval Net Depot along the Tiburon Peninsula. On the eastern shore, the infrastructure of Richmond includes the Richmond Pier and the Atchison Topeka and Santa Fe railroad, while the industrial site at Winehaven stands along the rugged coastline of Pt San Pablo.

Transportation across San Francisco Bay relied heavily on established water routes, including the Richmond-San Rafael Ferry and the Richmond-San Francisco Ferry before the era of modern bridges. Small residential pockets like Belvedere, Hilarita, and Tiburon contrast with the heavy industrial and military sites, providing a look at Marin and Contra Costa counties during a period of significant postwar development.
