Hello All. We have major drainage issues in our back yard caused by erosion and neglect by previous owners. We hired a civil engineer to help set new grade elevation marks with added fill to make the drainage work.
My question is what needs to be removed from the yard before new fill dirt is laid down. We were told to remove “all organic matter”. We have muck caused by standing water as well as patches of remaining grass. The elevation needs to be raised over a foot in some areas. The property is in Dayton Beach FL. Do we need to “skin” the entire yard prior to adding fill dirt or can we simply cover the existing grass up?
Thanks for any advice/input
