2015 Map of Sears Point

About this map

San Pablo Bay tidal marshes and the southern reaches of the Sonoma Valley define this landscape where water and land continuously negotiate boundaries. This 2015 survey illustrates a complex network of sloughs, including Steamboat Slough, China Slough, and Railroad Slough, which weave between historical settlements like Wingo and Schellville. The transition from the elevations of Wildcat Mtn down to the sea-level flats of Tubbs Island and Island Number One shows the geographical constraints that shaped local transport and agriculture. Small communities such as Fairville and Embarcadero are situated along the margins of these wetlands, connected by corridors like Sears Point Rd and the proximity of the Sonoma Valley Airport. The interplay of natural drainages like Sonoma Creek and Tolay Creek with reclaimed lands and islands provides a clear view of the hydrological engineering common to the northern reaches of the bay.
