I thought that was one of the more interesting holes on the course. Its meant to be a short par three as few people will likely venture back to the 7300 yard tees (and if they do they better hit it long anyway). The fill from the deep waste area was used to build up the surrounds and other areas of the course. It works pretty well I think probably in part because of the sandy nature of the soil. Some parts look more natural than others, but all things considered I liked what they did with moving dirt to create at least a little elevation change.
The green is fairly large as well, you'd have to hit a pretty poor shot to end up in the waste area. The course in general is pretty wide to accommodate some Texas winds.
