Portsmouth Maine is a tiny community adjacent to the Portsmouth Naval Shipyard on the Piscataqua River border with New Hampshire. The naval shipyard is one of the primary US facilities for nuclear submarine maintenance and overhaul. The tidal Piscataqua River creates flooding risk and the extreme tidal range of the Maine coast creates maritime safety considerations.
