Before a Flood

We can't always prevent localized flooding. But we can prepare for it. 

What you should know
  • Know if your property is in a flood zone. Check the 3D Interactive ​Floodzone Map.
  • Identify where you could go if told to evacuate. Consider the requirements of young children, the elderly, those with special needs, and all pets.
What you should do
  • Buy flood insurance. Standard insurance does not cover flood damage. Learn more. ​​
  • Create an inventory of your property and its approximate value. Keep the list, insurance policy, photos of valuables and receipts from valuables in a waterproof safe or safety deposit box.
  • Avoid building in the regulated floodplain. If you must build or renovate in a mapped floodplain, be aware that you must comply with additional regulations.
  • Elevate the furnace, water heater and electric panel if susceptible to flooding.
  • Install "check valves" in sewer traps to prevent floodwater from backing up into your home.
  • Listen to local TV or radio stations or check the Internet to stay aware of flood watches and warnings.​​ ​
  • Clean off storm drains near your home or business, removing any debris, leaves, and litter.
  • Report major stream blockages to 311.
  • Have a battery-operated flashlight. Have a battery-operated radio, TV, or Internet access that does not rely on electricity.
  • Create an emergency supply kit.  
  • Download FEMA's smartphone app​

In the Carolinas, heavy rain is often the result of fierce summer thunderstorms or slow moving tropical fronts. In the winter, flooding can result from Nor'easters.  Intense rain in the mountains can cause the Catawba River to overflow, flooding western Mecklenburg County.

Our community's rapid growth means there is less open space to absorb heavy rain. More structures are in the potential path of floodwater. Learn more about why it floods.
