Brawley anchors this 2018 survey of the Imperial Valley, a region defined by an intricate network of engineered waterways that sustain its agricultural heart. The map reveals the sophisticated irrigation and drainage systems essential to this desert basin, including major arteries like the Sandal Canal, Main Spruce Canal, and Rockwood Canal. These channels are complemented by dozens of specialized drains, such as the Rubber Drain and Dahlia Drain, which manage water flow across the arid landscape. Within the city limits, the Brawley Municipal Airport and residential street grids contrast with the surrounding rural sections. Genealogists and local historians can locate established burial grounds like Riverview Cem and Memory Gardens Cem, while the course of the New River meanders through the western portion of the quadrangle, serving as a natural landmark amidst the geometric precision of the valley's canals.
