Our yard is sloped only on one side. When we walk out of the basement it will be pretty flat. We were thinking of asking for a gradual slope on the backyard. Builder says they can either do a gradual sloe or a flat yard and a steep slope at the very end. I did not like the idea of steep fall at the end. The only issue that I see with gradual slope is I will not be able to put a trampoline/swing set for the kids
What can be done for the soil erosion on the left side of the house where there will be slope?
