About this map

The dramatic rise of the Diablo Range dominates this landscape, culminating at the iconic peak of Mt Diablo. From this high point, the terrain drops through complex ridges and canyons such as Mitchell Canyon and Donner Canyon, where numerous springs like Peach-Tree Springs and Moses Rock Spring feed the local watershed. The transition from these high wilderness areas to the valley floor is marked by a network of recreational paths, including the Black Diamond Trl and the Mt Diablo-to-Black Diamond Trail.

Suburban expansion from Concord, Clayton, and Walnut Creek pushes toward the foothills, evidenced by the California State Univ East Bay - Concord Campus and the residential clusters at Cowell. Historical land use is visible in the footprint of Nortonville and the engineered route of the Clayton Canal. This survey provides a precise record of the wildland-urban interface in the late 2010s, showing how modern development navigates the steep geography of Bald Ridge and Meridian Ridge.
