2018 Map of Otay Mesa

About this map

The international boundary between the United States of America and Mexico anchors the southern edge of this landscape, where the urban expansion of San Diego and Chula Vista meets the steep ascent of the San Ysidro Mountains. This modern era survey illustrates the complex infrastructure required for border-region commerce and utility, featuring the sprawling Brown Field Municipal Airport and the massive Second San Diego Aqueduct cutting through the terrain. The hydrology of the region is defined by the Otay River corridor, which feeds into the River Bottom Reservoir and is overlooked by prominent heights like Rock Mtn. Steep drainages such as Wolf Canyon and O'Neal Canyon illustrate the transition from developed mesas to the untamed highland canyons of the far southwest.
