In the case of Tuscon, where Brad Landcaster lives, it is the upper Sonoran desert. You go look at the wildlands, and the trees do fine. There are plenty of water to support the life that is there. There are lots of ways to work with that problem and Brad Landcaster pioneered them in Tuscon, including curb cuts. You use eddie basins (and other design patterns), along with native perennials. In the case of Tuscon, those would be the native trees of Sonoran -- palo verde, mesquite, cholla, prickly pear, etc. The curb cuts he pioneered inspired municipal laws, and Tuscon started implementing those and their own basins. The mesa that Tuson sits on top of used to have an aquifer. That's been depleted and the city has been pumping water uphill. It does not have to be this way.
