As you'll see, there really isn't much terracing to it. Someone posted the drawings yesterday on a thread started by David Hood at 3:35pm. I copy and pasted the link below but if it doesn't open you can search David's thread. Open the link to drawings and look at the section. As you'll see, the proposed design doesn't take much slope out of the hill. I'm betting the cheap aluminum fencing doesn't hold up for to many years.
