2012 Map of Corona South

About this map

Corona and its southern suburbs occupy the transition between the urban sprawl of Riverside County and the steep drainage basins of the Santa Ana Mountains. This 2012 survey captures the residential expansion reaching toward the protected canyon lands, with neighborhoods like El Cerrito and the intersection at Pepper Corner serving as local hubs. The northern half of the sheet is densely packed with a modern grid, including the historic Sunny Slope Cem, while the southern half remains dominated by deep geological cuts such as Tin Mine Canyon, Hagador Canyon, and Mabey Canyon. These canyons feed a complex network of seasonal washes, including Wardlow Wash and Main Street Wash, which channel runoff from high points like Pleasants Peak and Bald Peak toward the Temescal Wash in the northeast.
