With this interactive decision support tool, users can visualize future flood scenarios from sea level rise and storm surge, identify areas and populations at risk, and gain a better understanding of ecological, social, and economic impacts from coastal hazards. This information is particularly helpful for officials taking rising sea levels and increased storm intensity and frequency into consideration when making coastal management decisions such as coastal planning, zoning, and land acquisition. While the flooding scenarios and analyses in this tool were developed for the south shore of Long Island, the methods and models used are applicable for other geographies.
