When do I need a wetland permit?

The need to obtain a permit from the Wetlands Bureau is dictated by the following State Law; RSA 483-A:3, “ No person shall excavate, remove, fill, dredge or construct any structures in or on any bank, flat, marsh, or swamp in and adjacent to any waters of the state without a permit from the department. Please see the Wetlands Bureau website for more information or contact the Gilmanton Conservation Commission.
