2021 Map of Baldy Mesa

About this map

Victorville and Hesperia anchor the eastern side of this High Desert landscape, where suburban residential expansion meets the northern foothills of the San Bernardino National Forest. The prominent landform of Baldy Mesa dominates the central portion of the sheet, characterized by a transition from a grid-based road network to the alluvial fans of the San Gabriel Mountains. Engineering infrastructure is central to the area's development, notably marked by the Governor Edmund G Brown East Branch California Aqueduct, which cuts across the northern half of the map. The drainage patterns of the Oro Grande Wash and Manzanita Wash illustrate the natural hydrology that historical planners had to navigate. This survey also records utility corridors like the La Bureau of Power and Light Rd, reflecting the regional power and water networks essential to San Bernardino County's growth.
