About this map

Spring Valley and the expanding eastern reaches of Chula Vista anchor this 2018 topographic survey, showing a landscape defined by residential growth pressing against the dramatic relief of the Jamul Mountains. The map documents a sophisticated network of suburban development intertwined with preserved open spaces, such as the Sweetwater Reservoir and the Upper Otay Lake. Notable educational institutions including Cuyamaca College and Southwestern College serve as major hubs for the community.

South of Jamacha Junction, the terrain rises toward peaks like San Miguel Mtn and Mother Miguel Mtn, with the Sweetwater River Trail providing a corridor through the watershed. The area’s equestrian and ranching roots are still visible in naming conventions like Ivanhoe Ranch Rd and Fair Acres Ln. Distinctive landmarks such as Gobblers Knob and the airfield at John Nichol's Field offer specific points of interest for local researchers and genealogists.
