So I had a plumbing line in my lawn replaced last December after it started leaking. Now I have a hump in my yard that is dirt. Does anyone have any experience with this and know how long it will take to settle and should I plant grass seed on it now or wait until it settles down? I really don't know if the amount of dirt that is currently on it is too much or too little. The plumbing people that replaced the pipe just backfill and do not do any landscaping. Its only from my sidewalk to the street, so about 10 feet or so. Thank you!
