Preparing for a Flood
- Create an emergency preparedness kit with a 72-hour supply of water, including three gallons per person.
- Scan and store important documents on an online, cloud-based program.
- Put important documents and valuables in a water-proof container on the top floor of your home.
- Understand how to safely turn off electricity and gas lines in your home.
- Create an inventory of your household items and take photos of the interior and exterior of your home.
- Consider installing sewer backflow valves to prevent flood water from backing up into your home through drain pipes.
- Double-check sump pumps to ensure they are working properly. If possible, have a battery backup system.
- Keep materials like sandbags, plywood, plastic sheeting and lumber handy for emergency water-proofing.
- Find out how many feet your property is above or below possible flood levels. When predicted flood levels are broadcast, you can determine if you may be flooded.
- Raise or flood-proof heating, ventilating and air conditioning equipment by elevating equipment above areas prone to flooding. Another method is to leave equipment where it is and build a concrete or masonry block flood wall around it.
- Anchor fuel tanks. Unanchored fuel tanks can be easily moved by floodwaters.
During a Flood
- Turn off utilities if instructed to do so. Disconnect all electrical equipment.
- Do not walk through moving water. Six inches is enough water to knock you down.
- Do not drive in flooded areas. Six inches of water can cause you to lose control and two feet of water can sweep away your vehicle. Remember: Turn around, don't drown.
- Listen to local media reports for information about if the water supply is safe to drink.
- Avoid contacting flood waters because they can be contaminated by hazardous liquids and may contain sharp debris.
- Report and stay 25 feet away from downed power lines.
Driving in a Flood
- Flooding is the No. 2 weather-related killer behind heat. More than half of these fatalities occur when someone drives into floodwaters.
- Do not attempt to drive through a flooded road. The depth of water is not always obvious.
- Do not drive around a barricade. Barricades are there for your protection. Turn around and go the other way.
- Do not try to take short cuts--they may be blocked. Stick to designated routes.
- Be especially cautious driving at night when it is harder to recognize flood dangers.
After a Flood
- Listen to local media reports for information about the water supply safety.
- Avoid flood waters because they can be contaminated by hazardous liquids and may contain sharp debris.
- Be aware of areas that were previously flooded. The roads may be weakened or washed out.
- Report and avoid downed power lines.
- Clean and disinfect anything that was wet from the flood. Throw away any food that was touched by flood waters.
