Have your grass and water it too

So this is what happens when you try to grow grass in the desert. Neveda is the site of the largest growing city in the US - Las Vegas! So the water authority now needs to cope with unsuitable landscaping to keep up with the boom, and has developed an incentive program, Water Smart Landscaping, to motivate homeowners to cooperate. A couple of standouts:

I turned off the water on my grass already and it has started to die. Can I still qualify for the program?
Or how about this:
Won't Water Smart Landscaping make my house hotter and run-up my power bills?
No. Shade is the key to keeping you cool in the desert.
