About this map

Phoenix exhibits significant suburban expansion northward in this 2018 survey, centered on the Union Hills and the massive infrastructure of the Central Arizona Project Aqueduct. Residential development is highly organized into named communities such as Moon Valley, Little Deer Valley, and Desert Valley Estates, reflecting the rapid growth of the North Valley area. The Phoenix Deer Valley Airport serves as a major logistical anchor in the center of the map, while the Paradise Valley Community College and Buffalo Ridge park provide essential community services and recreation.

Water management is a dominant theme of the landscape, from the engineered path of the Central Arizona Project to natural drainage features like Skunk Cr, Cave Cr, and Apache Wash. The map also captures the varied topography of the Sonoran Desert, including the Dixie Mountain Loop and Adobe Mtn, where trails like the Great Horned Owl Trail and Hawk's Nest wind through the hills adjacent to modern arterial roads like the N Black Canyon Hwy.
