San Miguel Mtn and Mother Miguel Mtn dominate the central topography of this San Diego County region, where urban expansion meets preserved open space. To the northwest, the residential communities of Spring Valley, Casa de Oro, and La Presa represent the edge of the metropolitan sprawl, while the San Diego Nat Wildlife Refuge protects the heights of the Jamul Mountains. Significant water management features are evident throughout the landscape, from the Sweetwater Reservoir in the west to Upper Otay Lake and Lower Otay Lake in the south. The development of master-planned communities is clearly visible at Eastlake and Eastlake Greens, situated near the institutional campus of Southwestern College. The infrastructure connecting these valleys is defined by the Second San Diego Aqueduct and major corridors like Otay Lakes Rd and Telegraph Canyon Rd, which navigate the complex terrain of Telegraph Canyon and Proctor Valley.
