ok guys I need some opinions on this one. this wall is not my design and I am kind of skeptical about building it this way. it is using 6x6 timbers most are 4' sections. the wall stair-steps at both ends. the max height is 8 timbers. the first course is buried along with part of the second. It is built on a base of 57's with no other drainage. it has a slight outside curve. there is a 1/2" batter and every 2' a 5/8 rebar is driven through and 2' into the ground. this wall is retaining a decent size hill primarily clay. what do you think?
