About this map

Industrial developments and tidal marshlands dominate this mid-century coastal landscape where Suisun Bay meets the Carquinez Strait. The era's logistical footprint is evident in the expansive Naval Reservation at Port Chicago and the significant Oil Refinery infrastructure near Avon (Associated PO). These facilities are linked by a dense rail network, including the Southern Pacific and Atchison Topeka and Santa Fe lines, which navigate the low-lying terrain alongside Pacheco Creek.

On the southern edge of the bay, the planned community of Clyde sits near the Contra Costa Canal, while Vine Hill and the edge of Martinez showcase the region's residential growth. Significant water management features, such as the Mokelumne Aqueduct and Mallard Reservoir, highlight the vital role of utility corridors in supporting the Bay Area's post-war expansion. Local history landmarks like the Avon Sch and the IOOF Cemetery provide granular detail for genealogical research.
