This feature class resides within the SOCECON Feature Data Set of the Long Island Sound 2016 ESI geodatabase. It contains vector polygons representing Natural Hazard human-use resource data for Long Island Sound and adjacent lands and waters. The study area includes Long Island Sound, Peconic Bay, tributary watersheds, tidal tributaries, and freshwater streams and lakes, in New York and Connecticut. The vector polygons represent predicted flood inundation in the event of a Category 1, 2, 3, or 4 storm. For each storm category, the level of flooding is binned into anticipated depth of flood waters: <= 3 feet, > 3 feet, > 6, and > 9 feet. These are modeled data, based on the National Hurricane Center’s Sea, Lake and Overland Surges from Hurricanes (SLOSH) model (https://www.nhc.noaa.gov/surge/slosh.php). Raster model data, prepared in 2015, was converted to vector polygons for the purpose of the ESI. These data should be used for planning purposes only. The ArcGIS feature class (NATURAL HAZARD POLYS) has 2 associated attribute tables, considered as Entities or "Child Items" in this metadata record. Location-specific Type and Source information are stored in these related data tables, SOC_DAT and SOURCES (described below), which are stand-alone tables within the Geodatabase. This data set is a portion of the ESI data for Long Island Sound - 2016. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. Additional human-use information is provided in other feature class themes within the SOCECON Feature Data Set, including NAVIGATION/MARINE (POINTS, LINES, and POLYGONS), PARKS/MANAGED AREA (POINTS and POLYGONS), POLITICAL/JURISDICTIONAL (POINTS and POLYGONS), RESOURCE MANAGEMENT (POINTS and POLYGONS), and SOCECON (POINTS AND POLYGONS).
