Hurricane Inundation Maps

The U.S. Army Corps of Engineers, under the Hurricane Evacuation Study Program, develops information that assists Federal, State, and Local Emergency Management Officials in planning for and responding to a hurricane. Under this program, the Army Corps recently (summer 2009) updated the inundation maps for coastal areas in Rhode Island. The maps were developed using GIS software by overlaying the hurricane surge water surface elevations from Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model results on top of ground elevations from FEMA LiDAR data to show which areas would be inundated (flooded) by hurricane storm surge.

To learn more about the study and the production of the maps, read this document from the U.S. Army Corps.

Please keep in mind, these maps are based on the results from a worst-case scenario model and are intended to estimate areas of concern in the event of a hurricane. Do not rely on these maps in the event of a hurricane. These maps are provided as an informational tool to help consider impacted areas and even to help establish tougher land use guidelines and/or mitigation needs in areas that may be inundated.
