Flooding in Seabrook Island, SC

Flooding in Seabrook Island

Seabrook Island exists in a flood plain, and that’s not about to change. Due to its low lying coastal location, the town is susceptible to flooding from hurricanes and tropical storms. Here’s what you need to know about flooding in Seabrook Island, South Carolina, and what plans you can make to prepare for it in the event it does occur.


Flood planning involves preparing for the potential loss of power and the disruption of travel. You can first check to see if your property is located in a flood prone area by contacting the Town of Seabrook Island Zoning Department at (803)-768-9121 or you can search flood hazard zones online at the townofseabrookisland.org. Flood maps and flood protection materials are also available at Charleston County Public Libraries. As with any natural disaster event, creating a kit of emergency supplies that can tide you over until normal conditions are restored is an effective means of planning ahead. The Red Cross has developed a Flood Safety Checklist of items that it recommends including:

  • Water-At least a three-day supply; one gallon per person per day
  • Food-At least a three-day supply of non-perishable, easy-to-prepare food
  • Flashlight
  • Battery-powered or hand-crank radio
  • Extra batteries
  • First aid kit
  • Medication-a seven-day supply and medical items
  • Sanitation and personal hygiene items
  • Copies of personal documents (i.e. medication list, deed to home, birth certificates, insurance policies)
  • Cell phone with chargers
  • Multipurpose tool
  • Family and emergency contact info
  • Extra cash
  • Emergency blanket
  • Maps of the area
  • Baby supplies
  • Pet supplies
  • Extra set of house and car keys
  • Extra clothing, hat and sturdy shoes
  • Rain gear
  • Insect repellent and sunscreen

What to do during a Flood

If you live in an area where your home and property are being threatened by flooding, it is recommended that you turn off the electricity at the main disconnect. Additionally, if you use gas appliances it is suggested that you switch them off at the main disconnect as well. Home owners can also use sandbags to prevent water from entering vulnerable areas where it might seep in and inundate living spaces. Another option is to move furniture and other valuables to higher areas of the home.

Groups like the National Weather Service monitor severe storms and hurricanes and issue advisories, while the Charleston County Emergency Preparedness Division in turn notifies the Town of Seabrook Island so they can alert residents and visitors to potentially hazardous flooding conditions. If flooding conditions do occur, you are reminded of these important warnings:

  • Do not attempt to drive your vehicle or walk through floodwaters of an unknown depth. It only takes six inches of rushing water to sweep a person off their feet and most cars can be swept away by less than two feet of moving water.
  • Avoid standing water around utility boxes
  • If a flood or flash flood warning is issued for your area, head for higher ground and stay there


If severe flooding from a hurricane or other major storm appears imminent, evacuation orders may be given to residents and visitors. The Emergency Broadcast System will announce evacuations over TV, radio and cell phones. When evacuation orders are issued, people are advised to follow their instructions and leave within the specified time frame. The Town of Seabrook will issue any evacuation orders/permitted resident returns on its website as well as through the CODE RED warning system, the local media and the Town telephone service (888-314-3177).

The timing of returns to Seabrook Island following an evacuation will vary depending on whether there are still conditions impacting health and public safety.
