Being a low-lying, barrier Island, Sullivan's Island vulnerable to flooding. Whether it is heavy rains or storm surge, the Town is here to assist you with your planning and mitigation.
Flood hazard areas are areas located within the 100-year floodplain, which are defined as any area that has a one (1%) percent chance of flooding in any given year. Smaller scale floods (50-year and 10-year) have a greater chance of occurring in any year and can pose a significant flood hazard to people and property close to the ocean, sound, drainage channels and streams. Floods larger than the 100-year event can also occur.
The first thing you should do is check your flood hazard designation. The entirety of Sullivan's Island is considered to be located within a Special Flood Hazard Area (SFHA), also known as a Flood Zone. Maps and flood protection references are available for review at the Edgar Allan Poe Library. You may also visit the Building Department, located within Town Hall, to see where your property is located in the mapped floodplain. The Town maintains elevation certificates for new and substantially improved structures in the flood zone since 1977.
If you need assistance in determining your home's flood risk or need help with finding an elevation certificate, flood zone or other flood related information contact Floodplain Manager, Max Wurthmann at 843-883-5732 or firstname.lastname@example.org.
The Building Official is available for free site visits to your property to help you identify problem areas and give you tips on preventing flood damage. To request a site visit please call the Building Official directly at 843-883-5732.
