Kittery Maine is home to the Portsmouth Naval Shipyard — one of the nation's oldest and most significant naval installations, responsible for overhauling nuclear-powered submarines. The shipyard sits on Seavey Island in the Piscataqua River between Maine and New Hampshire and has operated continuously since 1800. The facility handles nuclear submarine overhauls creating specific radiological emergency planning requirements. York County sits in a seismically active region and the Piscataqua River creates flooding risk.
