A washed-out slope does not fix itself. We build retaining walls with proper drainage behind them, so the hill stays put and the water goes where it should.
Heavy spring rains on clay soil are a recipe for erosion. Most failed walls we see did not have drainage behind them; the water builds pressure until the wall gives.
A retaining wall holds back soil and the water in it. Without gravel backfill and a drain pipe behind it, water pressure builds after every rain until the wall leans or fails. That drainage layer is the part you never see and the part that matters most.
Usually water pressure behind it with no drainage. A new wall needs a drain path to last.
It depends on the material and site. Taller walls need engineering; we will tell you where that line is.
