About this map

The Santa Ana River carves a critical path through the northern reach of this landscape, separating the Chino Hills from the sprawling eastern edges of Anaheim and Yorba Linda. This 2018 survey reveals the sharp contrast between the densely developed suburban grids of Orange and Irvine in the west and the massive, undeveloped protected lands of the Cleveland National Forest and the Santa Ana Mountains to the east.

A network of drainage and terrain features defines the interior, including the prominent Black Star Canyon and Silverado Canyon. Notable water management and natural springs are recorded here, such as the Santa Ana Valley Canal, Horsetrough Spring, and Mustang Spring. The map documents the interface of urban expansion and wild topography, where roads like Deer Canyon Rd and Periphery Rd meet the steep slopes of Loma Ridge and the hidden floor of the Little Joaquin Valley.
