Sod
Instant lawns are highly appropriate here in the heat. Keeping lawn seed moist during germination is often difficult. Whether you're putting a tiny pool of green into a drought tolerant oasis landscaping, or you're laying out the next megaresort golf course, sod is an easy, and pleasingly inexpensive method of creating turf areas instantly.
Most days, you can just drive by Plant World and see a big pallet of sod out in front of the nursery. If you're smart enough to plan ahead, you can probably have the sod you need delivered to the jobsite, but if you live in the real, "oops-I-forgot" world, please just come by and get the sod when you need it..
