OK I've reviewed our great threads here and have some questions. I'm doing 2 different walls at 2 locations and in both cases I'm able to cut the existing ground exactly where I want the back of the walls to be. The are both going to be using natural stone, or what Steveair has described as PA Fieldstone. I'm in NJ also so my suppliers call it that too. Both will be no higher than 12"-14" above grade at their highest points. Being this low, is it absolutely necessary to back fill with gravel and provide the drain pipe if I'm able to build these against undisturbed & solid existing ground? The reason I'm asking is the one wall is going in a shaded yard with a beautiful lawn of moss. Yes moss. And if at all possible I'd like to not disturb it. The other one is at my house so if I can save a buck it would be cool. The one at my house is going where I had widened my driveway. My front lawn has a slight slope toward the street in front, so the wall would be running parallel to the natural drainage direction. So if I don't have to tear up any more of the turf & spend time & money with that, I'd be happy. I had cut the existing soil to widen the driveway 2 summers ago and there has been no erosion of that unretained wall of existing soil in that time. So I'm figuring it shouldn't be a problem to install the wall there with out the gravel and drain pipe. Should I reconsider for these 2 cases? Thanks for any comments & suggestions.
