FLOODPLAIN MAPPING SUBMISSION, NEWPORT COUNTY, RHODE ISLAND

The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). Coastal redelineation was completed for the coastline of Middletown within Newport County, Rhode Island. The 1 and .2 percent annual chance floodplain boundaries were delineated using 2' digital topographic contour data. Field verification was performed to validate primary frontal dune conclusions reached during the delineation. The redelineation of coastal floodplains is being incorporated into the countywide digital flood insurance rate maps.The file is georeferenced to earth's surface using the State Plane projection and coordinate system.The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.
