I am doing some work in my backyard as I am putting bamboo barrier between my neighbors and I property.
My Neighbor planted bamboos and all the rhyzomes have traveled across to my yard. The bamboo company came in and put a barrier in between to prevent the bamboos.
My question is, Do I need a retaining wall for the small slight difference in property height?
Also, would the bamboo barrier prevent water and cause water/soil pressure to push the side of the slope more into my yard??
I've added a before picture but it will look the same once dirt is pushed back.
Any advice, suggestion is welcomed.
