Service Description: The graduated flood risk maps were developed for 10-, 20-, 50-, 100-, and 500-year return periods. MBI performed spatial extent extrapolation and boundary delineation for return periods higher than 1 percent of the annual exceedance probability (AEP) for the current conditions and for all return periods for two SLR scenarios. Our team estimated wave heights in the extended floodplains using the total water level and still water elevation data and developed depth grids to quantify spatial flood depths for the five return periods of interest. This work was completed in February of 2025.
