I am looking for some suggestions on how to rebuild an eroded slope. The soil is mostly fat clay. When built, the slope had a 2h:1v slope to it, but over the years the top has gotten steeper while the bottom has gotten shallower due to sediment washing downhill. The toe has also begun eroding pretty severly. There are gullies 2' deep in some spots.
We need to get the bare soil covered with grass to keep more soil from washing away, but I need to get it back into the right slope first. I am thinking we excavate starting at the toe and work our way up. We can excavate, and put back a layer of compacted backfill. We can keep doing this until we repair the erosion, and cut it back to the proper slope. Then sod it all.
What is the general consensus about cutting into the toe of such a slope?
