Setbacks from wetlands?

[codeman671]

I am looking at a waterfront lot on the lake and have a question regarding setbacks. The lot is fairly narrow and down one side is an area of poorly draining soils, not swamp. How close can you build to this? The building envelope shown on the plan goes basically right up to it but no actual town or state approvals are in place, just the survey.

Also, how close can a driveway be to a lot side line in say Alton or gilford?
