About this map

The United States of America Estados Unidos Mexicanos border defines the southern extent of this 2021 survey, where the international line cuts across the coastal landscape of Border Field State Park. The region is a complex mix of military installations, dense residential neighborhoods, and protected wetlands. The Imperial Beach Naval Outlying Field occupies a significant portion of the southwestern corner, adjacent to the tidal reaches of the Tijuana River.

Inland, the map tracks the urbanization of South San Diego and the surrounding communities of Nestor, Palm City, and San Ysidro. The landscape is bisected by the Otay River, which flows through the Otay Valley toward the Otay River Marsh and San Diego Bay. Notable local landmarks such as Mount Olivet Cem and the Pima Medical Institute appear alongside numerous canyons, including Poggi Canyon and Dennery Canyon, which pocket the rising ground of Otay Mesa to the east.
