Ok, This is my last Hijack, I swear. At somepoint I'll start a thread in the OT area on designing this landscape.
But thanks to your help, here is my start on it.
What we have is a big triangle in the front yard. It used to grow grass, but out here, that takes a LOT of water. So we want to xeriscape it and put in several little terraced areas that will have small plantings of drought tolerant plants, and perhaps a 'BrentHenge' solar observatory of some sort...
So this is the first step, a little terrace down at the bottom.
