Good answers in this thread. As a consultant I agree with Krijack, you should make certain that you keep your building site options as open as you possibly can, before you start applying for permits. Don't do something that could possibly move a buffer, or setback without ensuring you absolutely do not need that space.

Andy, we need to go fishing again some time, I have a bunch of questions for you regarding this kind of stuff, both for business and some general advice type of things for this next house I am renovating.
