This document summarizes the impacts of Superstorm Sandy on Long Island, including multibillion dollar costs and damage from storm surge flooding. It outlines some of Long Island's responses to Sandy over the past 5 years, including various resiliency projects through state and federal agencies to improve infrastructure, protect homes and critical facilities, and restore natural barriers. However, it notes that the work has been piecemeal rather than regional, and that less than half of planned coastal protection projects and under 10% of homes in flood zones have been protected. It concludes that while progress has been made, Long Island is not yet ready to withstand another major storm like Sandy due to unfinished projects and the need for more comprehensive planning and protection efforts.
