About this map

Chileno Valley defines the northern reaches of this Sonoma County landscape, where the headwaters of Chileno Cr flow toward the coastal drainage system. The area's agricultural heritage is anchored by long-standing operations like the Walker Creek Ranch and Kahn Alley Ranch, reflecting the rural character of the region. Significant water management features dominate the southern portion of the map, including the Soulajule Reservoir and the Arroyo Sausal Reservoir, which capture runoff from the surrounding hills.

The topography is marked by several prominent ridges and drainage basins, with Three Peaks standing as a key landmark in the south. The complex network of winding watercourses, such as Walker Cr and Salmon Cr, has shaped the local transit routes, including the Petaluma Marshall Rd. This 2012 survey illustrates the contemporary balance between protected water resources and the enduring ranching culture of northern California.
