New floodplain maps for Kent, Sussex
State officials are developing new maps to identify areas at risk for flooding with help from the Federal Emergency Management Agency (FEMA).
About 70 miles of stream in Sussex County and seven miles in Kent County are being reexamined. DNREC Environmental Scientist Mike Powell says, “The most significant benefit of these new maps will be more accurate floodplain delineation. Based on new hydrologic analyses, the maps identify specific flood levels, providing detailed views of the 1 percent annual chance flood elevation – more commonly known as the 100-year flood level. This is the flood level a waterway can reach under extreme flooding conditions.” You can find draft copies of the maps online at rampp-team.com/de.
