Southeastern code is a minimum of 12'' deep, I'm not sure there in Buffalo.

The trencher made short work of it and having heat in the garage in the winter is well worth the hassle! Don't forget the copper tracer wire if you choose to use plastic. When filling in the trench I threw in phone & cable...
