1951 Map of Cordelia

About this map

Jameson Canyon and American Canyon serve as the primary conduits through the rising topography of the Sulphur Springs Mountains in this mid-century survey. The landscape reflects a period of significant post-war development in Solano County, particularly around the southern residential clusters of Chabot Terrace, Flosden Acres, and Harry Floyd Terrace. These housing areas were closely linked to the industrial and naval activity near Vallejo, anchored by facilities like the Permanente Foundation Hospital and the nearby County Fairgrounds. To the east, the junction at Cordelia remains a vital transportation hub where the Southern Pacific railroad meets the canyon passes. Evidence of the area's extraction history is visible at the St John Mine and a Quarry, while the presence of the Olympic School and Green Valley Sch documents the community infrastructure supporting these growing neighborhoods.
