Flood Protection Information
Flooding is a major hazard in the City of Folly Beach. The greatest threat for flooding in Folly Beach is from storm surges associated with a hurricane from the Atlantic Ocean. Folly Beach has experienced many hurricanes and other severe storms throughout our history, the most recent of which were Hurricanes Hugo in 1989 and Hurricane Floyd in 1999. In 2011 Tropical Storm Irene resulted in heavy flooding in parts of the island. Remember though, flooding doesn’t have to come from hurricanes. Heavy rain and even extremely high tides can cause floods. Because of the flat topography, flooding can occur almost anywhere in the city. Being prepared is your best defense against a flood.
The information on this page can help you prepare for flooding, protect your property, and keep your family safe.
Know Your Flood Hazard
- The entire City of Folly Beach is in a flood hazard area. Maps of your specific location can be found at the Federal Emergency Management Agency (FEMA) Map Service Center. You can see that the city has identified problem areas here.
- It is important that you have a plan to protect yourself and your family in the event of a flood. Your plan should include at a minimum, an evacuation route, arrangements for shelter, contact information, and a supply kit.

If flooding threatens your home, turn off the electricity at the main breaker. If you lose power, turn off all major appliances.
- Turn off the gas and be aware of gas leaks. Use flashlights to inspect for damage. Do not smoke or use candles, lanterns or open flames unless you know the gas has been turned off and the area has been ventilated.
- Discuss your family emergency plan. Your family may not be together when disaster strikes, so it is important to know how you will contact one another, how you will get back together, and what you will do in case of an emergency.
- Various methods may be used to minimize flooding such as elevating your structure (see the links below). If a flood is imminent, protect your property by sandbagging areas subject to the entry of water. Valuables and furniture can be moved to higher areas of the dwelling to minimize damage.
- The Folly Beach staff can make site visits to provide one-on-one advice to property owners regarding flooding and drainage issues on private property. For additional information, please contact the city Building Department at flood@follybeach.gov.
- The Federal Emergency Management Agency maintains an electronic library of reference materials on topics such as retrofitting structures for enhanced flood and hurricane resistance and protecting building utilities from flood damage. The Charleston County libraries also have multiple publications available in their reference sections on protecting property from flood damage. Since Charleston County is subject to hurricanes, measures such as protecting glazed openings in your building against high wind damage should also be taken for property protection.
- Note that information on flooding can also be found at the Folly Beach Public Library: Elevating Your Floodprone Home, Coastal Construction Manual, Elevated Residential Structures, Protecting Manufactured Homes From Flood Damage, Mitigation of Flood and Erosion Damage to Residential Buildings in Coastal Areas, Protecting Building Utilities From Flood Damage.
- The best place to start your research on Flood Insurance is the homepage of the National Flood Insurance Program. You can find out who needs flood insurance, what it covers, the current coverage limits (1-4 Family Residential $250,000 structure and $100,00 for contents and Business Structure $500,000 and Business contents $500,000), rates, and lots of other useful information. There is a 30-day waiting period before your insurance goes into effect.
- Folly Beach participates in the National Flood Insurance Program. This means that any home or business in the city can be covered by a flood insurance policy.
- Flood Insurance covers a building’s structure and contents. The structure generally includes everything that stays with a house when it is sold, including the furnace, cabinets, built-in appliances, and wall-to-wall carpeting. There is no coverage for things outside the house, like the driveway and landscaping. Detached garages and accessory buildings are covered under the policy for the lot’s main building. Renters can buy contents coverage, even if the owner does not buy structural coverage on the building.
- Federally subsidized flood insurance is available through the National Flood Insurance Program for most properties located in Folly Beach. Damage caused by flooding is not covered by a standard homeowner’s insurance policy. A separate flood insurance policy is required for flood peril coverage. Flood insurance is available for buildings only, contents only, or both buildings and contents. Insurance agents or the National Flood Insurance Program should be contacted for flood policy information.
Repetitive Loss Properties
The City of Folly Beach participates in both the National Flood Insurance Program (NFIP) and the Community Rating System (CRS). As a result of participation in the CRS program, property owners in the City receive a discount on their yearly flood insurance premiums. One of the requirements of the CRS is the identification and monitoring of repetitive loss areas. The city is required to provide information on flood protection measures and flood insurance to owners of properties in these areas.
If your property has been identified by City of Folly Beach as being in an area that is subject to repetitive losses from flooding, you receive an annual notice from the city. Any properties in your area that have experienced two or more flood events in a ten-year period (this may not have been in the last ten years) are considered to be repetitive loss properties. Even if your property has not experienced flooding in the last few years, it could be susceptible to flooding during any flood event. There are many ways to reduce the flooding hazard on your property, such as:
- Elevation: This method consists of raising a house on an elevated support structure to place it above future flood waters. The exact method can include a number of possibilities that depend on local conditions, including flood and wind forces, building type and size, and soil bearing capacity. On Folly Beach, elevation is the most effective means of protecting your property.
- Relocation: This is the most drastic of all flood protection measures; it is also the most effective. Moving a home from a flood-prone area to a location outside of the floodplain is the only way to guarantee that you will escape future flooding. Unfortunately, the entire City of Folly Beach is in the floodplain.
- Berms and Levees: In areas of shallow and moderate flooding, it may be possible to create a barrier of compacted soil to keep the water away from your house. This is one of the most inexpensive means of flood protection and can be attractively landscaped. This method requires continued monitoring and maintenance.
- Floodwalls: This method is also appropriate for areas with low to moderate flood depths and velocities. Floodwalls are constructed of masonry or concrete block and keep water away from the house much like levees and berms. Floodwalls are more expensive, but require less monitoring and maintenance.
- Closures: Closures are often used with other techniques such as flood walls and levees. Closures protect gaps from windows, doors, walkways, and driveways.
- If you have any questions about the NFIP, CRS, repetitive loss, or possible improvements to your property please feel free to email the Building Department at flood@follybeach.gov.
Building in the Floodplain
Managing the Natural Functions of Floodplains
- First and foremost, make certain the building is structurally sound and is not going to collapse or cause other physical harm prior to entering a damaged structure. Shut off the electrical and/or gas service to the structure if there is any possibility that the service is damaged. Notify all applicable insurance carriers of the damage immediately to begin the claims process.
- If your property is one of many damaged by an event, make sure the address of your property is clearly indicated for inspectors and insurance adjusters.
- Take photographs of any damaged areas. Secure the property from any additional damages if possible. Wait for your insurance company to give you clearance to begin cleaning up damaged areas.
- The Federal Emergency Management Agency also has information available online regarding the first steps to take after a flood and about repairing your flooded home. Be careful to avoid injury during post-event clean-up and salvage operations. Make sure any contractors you hire to repair your property are licensed or registered for the type of work they are performing and obtain applicable permits prior to starting work on your property.
- The Building Department maintains copies of flood elevation certificates for all new construction and substantially improved structures. If your structure was after 1990, we may have an elevation certificate on file for your structure. For structures where an elevation certificate is not available on file, a S.C. Registered Land Surveyor will need to survey the elevation of the structure and complete the flood elevation certificate form. The City of Folly Beach does not survey structures for the purpose of completing flood elevation certificates. Please email the Building Department at flood@follybeach.gov for questions related to elevation certificates.
