About this map

Avon (Associated PO) and the industrial reaches of Mococo define the mid-century landscape where Contra Costa County meets the Suisun Bay. This 1959 record, with revisions through the late 1970s, captures a pivotal era of infrastructure and industry. Heavy rail corridors of the Southern Pacific and Atchison Topeka and Santa Fe converge near massive installations like the Oil Refinery and Monsanto plant, illustrating the region's transition into a major petrochemical and logistics hub.

Residential and military life exists alongside these industrial giants, visible in the layout of Clyde and the sprawling footprint of the Naval Weapons Station Concord. Local educational and memorial sites, including Las Juntas Sch and Memory Gardens Cemetery, provide essential anchor points for genealogists. The intricate waterways of Pacheco Creek and Goodyear Slough reflect the complex environmental interface of the Sacramento-San Joaquin River Delta before later 20th-century developments further altered these shorelines.
