Overview: Tract Development, Sun City and Salton City, p. 506

Sun City

Sun City: This suburb of Phoenix claims to be the first and largest planned retirement community in America . It has seven recreation centers, eight golf courses, three country clubs, two bowling centers, and an artificial lake. All this greenery takes a lot of water in the hot, dry Arizona climate. Note the abrupt boundary between the verdant neighborhoods of Sun City and the surrounding desert. As you can see from this aerial view, housing units are built in concentric circles and long, undulating streets that make an interesting pattern from above but preclude much pedestrian traffic.
