Palm City is a neighborhood in the southern section of San Diego. It neighbors Otay Mesa West to the south and east, Egger Highlands and Nestor to the west, and Chula Vista to the north. It also serves as a gateway to the beach cities of Imperial Beach, and Coronado, by way of the Silver Strand isthmus, due to it being where California State Route 75 meets Interstate 5. Major thoroughfares include Coronado Avenue, Hollister Street, Beyer Boulevard, and Palm Avenue.HistoryPrior to the Mexican-American War the area that is today Palm City was part of Rancho La Punta, sometimes referred to as Rancho Melijo, granted to Santiago Emilio Arguello in 1834. The U.S. Land Commission rejected his claim, opening up the area to settlement; which in turn led to the creation of communities in the area.In the 1880s, John J. Montgomery built and designed his own ornithopters and manned glider designs at the Montgomery family Fruitland Ranch near what would become Palm City. His gliders were tested on the surrounding hillsides of Otay Mesa. These flights represented the first of their kind in the nation.
