Alone among the cities of the American Southwest, Phoenix is the oasis. It has always been so, but whether it remains an oasis city is starting to come into doubt. A common narrative is that Phoenix attracted Midwesterners who wanted to recreate the landscape from which they came.
This is untrue. In fact, the early Anglo residents were from many regions, especially the South. And the oasis predates American settlement. The archeology of the region is in flux, but it appears that "plant husbandry" was being performed by prehistoric tribes as early as 3,000 or 1,500 B.C. (or BCE if you are trapped in the politically correct precincts of academia). By the first millennium A.D., the most advanced irrigation in the New World was being perfected by the Hohokam.
The Salt River Valley was an ideal location, with rich alluvial soil that would grow anything — just add water. The altitude and weather in the modern climate era allow for two or more growing seasons depending on the crop. Maize was imported from Mesoamerica. Cottonwoods, willows and other native shade trees grew along the riverbank and its subsidiary creeks. I have no doubt that Hohokam dwellings were well-shaded. The new settlers merely took it to a higher level.
The photo above captures the oasis city at its zenith, in the 1960s. Note the inviting public space provided by shade and grass surrounding an inspiring art deco building. This was the Phoenix I grew up in. At 10,000 feet, you would have seen a green city surrounded by bands of citrus groves, farm fields and horse pastures. And then: The majestic, largely untrammeled Sonoran Desert. What a place to live. The older neighborhoods were graced by mature trees and parking lawns, a grassy area between the curb and sidewalk. Encanto Park was an oasis within an oasis. Central, as you see below, was lined with palm trees. North of Camelback were shady acreages, often along streets with an abundant shade canopy, set back behind irrigation "laterals." My great aunt lived in one: It was a wonder of shade and tranquility behind oleander hedges on Seventh Avenue. Well into her eighties, this daughter of the frontier would walk out every Sunday evening to turn the valve and "take her water," the flood irrigation from the Salt River Project.
In our neighborhood, what is now Willo, few families had pools but most put in winter lawns to give the sweet season its magical green. Even driveways had grass between two narrow concrete strips. This was not the Midwest. It wasn't LA, although the parking lawns were imported from there. Instead, Phoenix created its own unique urban aesthetic. It wasn't planned. This Eden just happened. If you missed it, you have my deepest sympathy. Many areas of oasis beauty remain. If you want a sense of the practical benefit, drive south from Osborn on Fifteenth Avenue some summer evening with the windows down. When you cross Thomas into Encanto Park, the temperature will drop by ten degrees or more.
