Oh, oh. Wegman Companies. Rochester, NY. You eat well? Related? I see now what you do. Why do you suspect that bad fill will impact you? 14' is not too bad if you are digging a basement for a single. If you are doing townhomes, that would be different.
One other concern you should have. You say 14 or so acres is back fill. That's a lot of back fill and in an area like Rochester, I would definitely want to know what else is in there? You don't want to find the next superfund site 2 blocks away from Kodak, do you?
