How to Protect a Home in a Flood Plain

Place copies of all important paperwork in a waterproof container in the event of a flood. Include insurance information and a room-by-room inventory of all possessions. You may also want to consider investing in a second container for irreplaceable family possessions such as photographs.

Prevent flooding at your home's foundation by keeping gutters and downspouts clear and free-flowing. Runoff from roofs can create depressions along the base of your house and increase the risk of damage from seepage.

Place all electrical appliances such as your water heater or furnace on cement blocks. Consult your insurance agent to determine what the projected flood elevation area is in the floodplain. Ideally, appliances will be located 12 inches or more above this level.

Make sure all electrical outlets are situated above the projected flood elevation area as well. Consult a professional electrician if any outlets need to be relocated.

Install a backup on your sump pump system. Surface flooding will occur around a home in a floodplain. Opt for a battery-powered unit in case of a power outage, which may accompany a severe storm.

Prevent water backup during floods by installing check valves on drains within your home. Flood waters can contain potentially hazardous bacteria and toxins, especially in cases of sewer or septic tank flooding. Check valves are available online and at home improvement centers.

Seal concrete walls and floors with seal coat or a rubber coating product available at home improvement centers. Repair any cracks or damage prior to sealing.

Reduce the amount of impervious surfaces around your home. Homes in floodplains are at risk as it is. Impervious surfaces such as sidewalks and driveways remove areas that may absorb floodwaters, increasing the potential for flood damage. Replace impervious surfaces with clump-forming grass sod to provide additional erosion protection.

Restore wetlands in the area surrounding your home. Floodplains often include areas of wetlands. Wetlands act as sponges, absorbing excess flood waters. They can also absorb impacts from storm surges. Contact your agricultural extension office or state natural resources agency for assistance.
