Tucson has a shocking amount of renewable water. Shocking because we waste virtually all of it — if we care what we use it for, rather than who “owns” it.
To see what we could do with our rain — if we choose to — check out this Prezi presentation. It is a toolbox for a dozen or more tools that we can use throughout Tucson to transform Tucson into a rain watered, edible forest, that shades our streets and brings us together. Or view the transformation of an existing neighborhood intersection into a micro-Food Park, thanks to the magic of Photoshop.
This is not a unique idea. For instance, the American Society of Landscape Architecture just put out this animation of how to transform a city so it produces lots of food.
Neighborhood micro-Food Park
Almost any street in any neighborhood could become a center for establishing community, harvesting water, and Feeding Tucson. Check out this example of the conversion of a conventional neighborhood intersection into a µ-Food Park.
Pay special attention to the Drywell. Phoenix has over 50,000 of them. Pima County has a couple of dozen. They can be used to recharge filtered rainwater into the aquifer – 100s of thousands of gallons each.
