Imperial County Airport — Imperial, United States

IPL identifies Imperial County Airport, serving Imperial, California, in the agriculturally rich Imperial Valley near the Mexican border and the Salton Sea. The airport supports crop-dusting and agricultural aviation central to the valley's farming economy, along with general aviation, flight training, and some limited scheduled or seasonal commercial service over the years. Imperial County's desert climate and irrigation-fed farmland make it one of the most productive winter vegetable-growing regions in the United States, and IPL plays a supporting logistics role for this agricultural base. The airport's proximity to the border city of Mexicali also gives it relevance for cross-border business and general aviation traffic in the region.
