About this map

The San Pablo Bay National Wildlife Refuge dominates this mid-century survey of the northern shoreline where the Petaluma River meets the bay. The landscape is defined by vast expanses of mud flats and tidal marshes protected by an extensive system of levees. Transportation through this wetland environment is anchored by the Northwestern Pacific railroad corridor, which skirts the western edge near Black Point.

To the south, the terrain rises at the historic China Camp area along North San Pedro Road, providing a contrast to the northern island geography of Tubbs Island and Day Island. Notable infrastructure including a Rescue Tower and a wide pipeline area cut across the tidal zones. The map also delineates several municipal and county boundaries, including the Vallejo City Bdy and the Richmond City Boundary, meeting in the open water of San Pablo Bay.
