About this map

The tidal landscape of Suisun Bay and its complex network of islands and sloughs dominate this 2015 study. The northern section is defined by a mosaic of low-lying terrain including Hammond Island, Simmons Island, and Van Sickle Island, separated by the winding Montezuma Slough. These marshlands sit just south of the Sacramento Valley and Central Valley entrance, reflecting the intricate geography of the Sacramento-San Joaquin River Delta.

South of the bay, the terrain transitions sharply into the residential and industrial corridors of the Diablo Range foothills. Urban development is concentrated along the southern shoreline in communities such as Bay Point, McAvoy, and Shore Acres. Critical infrastructure is clearly visible, including the Mokelumne Aqueduct and the Contra Costa Canal, which weave through the suburban landscape toward Cornwall and Diamond. The map captures the meeting of the industrial East Bay with the preserved wetlands of the San Joaquin Valley interface.
