Brawley serves as the focal point of this Imperial Valley landscape, where an intricate web of irrigation infrastructure dictates the pattern of human settlement and agriculture. The city's northern edge is defined by the New River and Riverview Cem, while the industrial and transportation needs of the early 21st century are visible at the Brawley Municipal Airport and Grape Siding. The map reveals the critical importance of water management in this desert environment, with major arteries like the Central Main Canal, West Main Canal, and Rockwood Canal feeding a dense grid of smaller laterals and drains.
