Yep, I started the traditional gabion wall but it is tedious and I thought there must be a better idea. An engineered wall doesn't require all the bulk that a gabion has. They have a toe extending under the backfill so here's a hybrid idea.
The Kit Home came with a floor kit but the stumps were "by owner" and required an engineer to sign them off. Instead of using hurdles, I used two mixer loads per stump and placed them one at a time.
