FEMA Releases Updated Flood Maps for Hilton Head Island
Hilton Head Island, S.C. (September 29, 2020) – The Federal Emergency Management Administration (FEMA) has released updated, digital flood hazard maps that show the extent to which areas throughout Hilton Head Island are at risk for flooding.
The Flood Insurance Rate Maps (FIRMs) are based on updated coastal modeling and shows flood hazards more accurately than older maps. These maps will become effective for flood insurance rating on March 23, 2021.
FIRMs indicate whether properties are in areas of high, moderate or low flood risk. “Over time, flood risks change due to weather events, environmental changes, erosion, land use and other factors,” said Shari Mendrick, the Floodplain Administrator for the Town of Hilton Head Island.
“Maps are updated periodically to reflect these changes. However, the Town Hilton Head Island FIRMs have not been updated since 1986,” Mendrick said. “In reviewing the new FIRM, many property owners may find that their risk is higher or lower than they thought. If the risk level for a property changes, so may the requirement to carry flood insurance.”
The updated flood map allows property owners to make better financial decisions about protecting themselves and their property. The map also helps community officials, engineers, builders and others make important determinations about where and how new structures and developments should be built, making the Town of Hilton Head Island a safer place to live.
