About this map

Harlingen and its neighbors in the Rio Grande Valley are defined by an intricate network of irrigation and transportation corridors. This modern topographic view traces the engineered landscape of the South Texas plains, where the Arroyo Colorado winds through a dense grid of canals, including the Number Seven Canal and Harlingen Main Canal. The development pattern reflects a transition from agricultural roots, seen at Shofner Farms Airport, to regional infrastructure like the Valley International Airport and the sprawling campus of Texas State Technical Coll Harlingen.

Residential growth connects Combes and Primera in the north to the urban centers of Harlingen and San Benito in the south. The reliance on managed water is evident in the City of Harlingen Reservoir and the various numbered laterals like Lateral T Canal, which supported the valley's citrus and vegetable industries before suburban expansion. Major transit arteries like US Hwy 77 provide the primary north-south spine for this interconnected metropolitan area.
