We have done many retaining walls , from whatever up to 800 sq. ft. Also over 4 ft. . Here's the question. How do any of you build terraced walls that would rise 16 ft in 4 lifts over a 35 foot run? I know the construction aspect and the engineering aspects. What I'm looking for are material logistics. How do you get your rock to the middle terraces? How do you get your backfill there? Any creative ideas that have worked and any other experience would help. Actually thought about getting a small pole crane for this . What do you think?
