If your home was not built to withstand rising water, some flood-proofing work may be required in order to minimize flood damage. Here are some methods of flood control that will protect your home from rising water.
Raise your electrical outlets and switches. All outlets, switches, sockets, and circuit breakers should be at least one foot above flood level in order to prevent significant electrical damage in the case of a flood.
Point your downspouts away from your home. If your gutter runoff is not pointed away from your house, and in an appropriate direction, it will pool at the corners of your house and may eventually create leaks in your basement.
Raise your home on stilts or piers. While expensive to conduct retroactively, raising your house on stilts will raise your house's flood level. Since even an inch of flood water can lead to significant damage, raising your home above the flood level will substantially protect your home.
How To Limit Damage After Flooding Has Begun
-Turn off the water line, if that is the source of the flooding.
-Clear out your gutters and drains so that water can flow freely through them.
-Use sandbags to block any gaps that will lead to flooding.
-Shut off your electricity at the breaker panel, should flood water be close to reaching your electrical system.If it's not raining, open multiple windows to allow air to flow through your home.
-Photograph or videotape any flooding in order to document and defend your claim with your flood insurance provider.
