About this map

The Vallejo Home State Historical Monument and Mission San Francisco Solano Vineyard anchor this detailed study of the Sonoma Valley. The landscape reveals a transition from the historic Pueblo Lands of Sonoma to the burgeoning resort communities of Fetters Hot Springs, Boyes Hot Springs, and Agua Caliente. To the east, the topography rises sharply into the Napa County line, marked by elevations like Mt Pisgah and Bismark Knob.

Transport and industry are well-defined, from the Northwestern Pacific corridor to localized quarries and gravel pits near the Arroyo Seco. Purple overlays indicate the late-1960s expansion of urban boundaries, contrasting with the earlier 1951 survey and highlighting the growth of residential pockets like Mission Highlands and El Verano. Local education and health infrastructure are noted through the Sassarini Sch, Sonoma Valley Hospital, and the secluded Mont La Salle School in the hills.
