About this map

The United States Mexico international boundary defines the southern edge of this 1941 survey, where the Tia Juana River and Otay River cross the coastal plains of southern San Diego County. The landscape is a mix of early residential developments and agricultural infrastructure, with clusters of growth in Imperial Beach and San Ysidro. Transportation is dominated by the San Diego and Arizona Eastern River railroad and the Southern Pacific line, which connect the border region to San Diego Bay.

Salt production is a visible industry at the Salt Works near the mouth of the Otay River, while the eastern terrain transitions into the rugged drainage of Smuggler Gulch and Goat Canyon. Local education and community life are marked by the presence of Southwest Jr High Sch, Emory Sch, and the San Diego Country Club near Castle Park. These labels document the region's mid-century character before the rapid post-war expansion reshaped the South Bay.
