Flash Flooding
Although “flash flooding” is a sudden weather-related hazard, that doesn’t mean you can’t be prepared for it, and be ready to take action. In fact, before the first raindrop falls, you should know if you neighborhood, house or general area is a flood risk. Your community officials or local emergency management office should be able to provide you with the history of flooding in your region. It’s essential to know whether your house is on a flood plain, and if it’s above or below the flood stage water level.
If it is, you have to be prepared for the eventuality of a flash flood by having disaster supplies at the ready. Stock everything from flashlights, extra batteries, first aid kits, non-perishable food, bottled water, essential medicines, sturdy shoes, a battery-powered radio, and extra cash and credit cards on hand. It’s also advisable to stock up on emergency building materials such as plywood, plaster sheeting, nails, shovels, sandbags, and other tools. Install check valves in building sewer traps to prevent flood waters from backing up in sewer drains.
Knowledge is power in such an emergency and you must teach your children how to respond after a flood or flash flood. They should know how and when to turn off the gas, electricity or water, how to call 9-1-1 or other local authorities, and where to meet if the family is separated.
You should also have a detailed evacuation route planned out in advance. What roads lead to higher ground? Avoid any streets that become flooded with the first major rainfall. Know where the nearest shelters are and have alternative routes should one road be rendered unusable.

You’ll also need to set up an emergency communication plan. What if the flood hits when the kids are at school or the parents are at work? Everyone must know in advance where to meet. Establish an out-of-area “contact” person, usually an out-of-state relative or friend. Everyone in the family should know the name, address, and phone number of the contact person, so they can call and describe where they are and how they are doing.
DOs AND DONT'S DURING A FLOOD
- Don't drive or walk through a flooded area; more people drown in their cars than anywhere else. People have been knocked off their feet by rushing water no deeper than six inches. For obvious reasons, stay away from downed power fines and electrical wires. Look out for animals - especially wild ones, such as snakes.
- If you’re in your house and the water is rushing in, go to the second floor, the attic, and if necessary, the roof. Take a flashlight, a portable radio and dry clothing with you, then wait for help. Attempting to swim to safety is far more dangerous than waiting for rescuers.
- Don't return home until authorities indicate it is safe to do so. Once you get home, survey the damage from the outside and call your insurance company to file a claim right away. Be extremely careful when entering your home or building. Look closely for cracks in the foundation or other major damage. When inside, never use matches or any open flame. The chance of a gas leak is considerable. Make sure the power is off until an electrician gives you the go-ahead. Be careful when you inspect the residence interior. The floors are often slippery and may contain pieces of broken glass or other dangerous debris.
- Do clean your house right away because floodwaters often contain sewage. All food and medicines that are wet from floodwater must be thrown away. Until local authorities proclaim your water supply to be safe, boil water for drinking and food preparation vigorously for five minutes before using.
The best defense against flooding is a good offense, and that’s flood insurance. Flood damage isn’t covered by homeowner’s insurance, so if you live in a flood plain, get flood insurance from your insurance company or agent. Don’t put this off, because it takes 30 days after purchase for the policy to go into effect.
