About this map

San Diego Bay dominates this coastal landscape, serving as the focal point for a massive naval and aviation presence during the interwar years. Military facilities line the waterfront, from the U.S. Naval Training Station and US Marine Base in the north to the U.S. Naval Destroyer Base further south. Aviation history is centered on North Island, which houses Rockwell Field (Aviation) and the U.S. Naval Air Station adjacent to the newly established Lindbergh Airport.

Beyond the urban grid of San Diego and Balboa Park, the southern portion of the sheet reveals a series of land grants including La Nacion and Otay. The San Diego and Arizona Railway and Southern Pacific Lines connect coastal towns like National City, Chula Vista, and Imperial Beach with the border community of San Ysidro at the United States Mexico boundary. The map captures a moment of transition from agricultural valleys like the Sweetwater Valley to a modern maritime and military hub.
