Chris definitely check out Brad Lancaster's work. Also Gary Paul Nabhan has some great stuff for your region.
Art LUdwig has some great stuff on greywater use that will probably be helpful in your region too--you'll want to use water extremely well, both coming and going.
Generally, though, if forest is not the natural vegetation of your region, then forests are not what you should mimic. Not that it's impossible: Irrigation can make the difference, as can careful microclimate design, but I'd be cautious--don't want to make your soils salty, or become dependent on unsustainable resources! Mimic the natural vegetation of the region, mostly, and modify a small area if you can. Or move! Hate to say that . . . but my sense is that Phoenix is living on ancient and/or very distant water, and ancient sunlight (oil) is all that makes it possible for the tens of thousands there to survive. But I don't know the whole scene, so don't take my word for it--others know the situation better than I. I'm sure there are
local examples you can bounce off of.
Best wishes!
