The agricultural landscape of the Rio Grande Valley is defined by a dense grid of irrigation infrastructure and rural settlements in this 2013 survey. Central to the region's connectivity are the towns of Elsa and Edcouch, where the residential street grids contrast with the surrounding rectangular farm plots. Aviation plays a visible role in the local infrastructure with Cannon Aviation Nixon Airport and Skalitsky Airport located near the town centers. Water management is the lifeblood of this terrain, anchored by the Main Supply Canal and the Donna Drain, which feed into the extensive network of miles-numbered roads.
