About this map

The Northwestern Pacific railroad corridor anchors this survey of southern Sonoma County, showing the region during a period of significant suburban transformation. Centered on the city of Cotati, the map reveals the emergence of Rohnert Park and the campus of Sonoma State College, both shown in purple tint to indicate urban expansion through the late 1960s. This growth contrasts with the surrounding agricultural and industrial landscape, marked by several quarries and the expansive Cotati Naval Auxiliary Air Station (Inactive).

Tracing the historical topography from the Sonoma Mountains down to the Petaluma River, the map identifies long-standing rural community centers like Penngrove and Stony Point. Genealogists and local historians can locate early educational and civic landmarks, including Liberty Cemetery and schools such as Cinnabar Sch and Waugh Sch. The network of older transportation routes, including the Old Railroad Grade and the Redwood Highway, provides a clear view of the area's movement away from rail-based commerce toward highway-driven development.
