2015 Map of San Dimas

About this map

San Dimas and Pomona anchor a landscape defined by the transition from the San Jose Hills to the extensive canyon systems of the south. This 2015 survey details a dense suburban corridor where major institutional grounds like Cal Poly Pomona, Mt San Antonio College, and the University of La Verne occupy significant acreage alongside the Puddingstone Reservoir. The topography is marked by notable heights such as Buzzard Peak and Elephant Hill, which overlook a network of water management features including the San Jose Creek Diversion Channel and Big Dalton Wash. For local historians, the map preserves the locations of significant community sites including Evergreen Cemetery, Spadra Cemetery, and Oakdale Memorial Park, documenting the established footprint of Diamond Bar, Walnut, and West Covina at the start of the 21st century.
