New Jersey faces extensive flood risk from Atlantic coastal storm surge, tidal flooding in bays and rivers, and riverine flooding along the Delaware, Raritan, Passaic, and Hackensack rivers. Hurricane Sandy in 2012 was the state's worst natural disaster causing over $30 billion in damage and flooding thousands of properties along the coast and in inland communities. The Meadowlands region in Bergen and Hudson counties is one of the most flood-prone urban areas in the nation. The Passaic River regularly floods through Paterson, Little Falls, and other communities, with the 2011 Tropical Storm Lee flood causing extensive damage. The Delaware River creates significant flood risk for communities in western New Jersey including Trenton, Easton, and Phillipsburg. The Raritan River floods through Somerset and Middlesex counties affecting densely populated suburban areas. New Jersey has over 500 NFIP-participating communities and leads the nation in flood insurance policies per capita. The state's position between the Atlantic Ocean and the Delaware River creates compound flood risk. Sea level rise projections of 1-3 feet by 2060 will significantly expand coastal flood zones and increase tidal flooding frequency throughout the state.
