Before a Flood
• Avoid building in a floodplain.
• Construct barriers (levees, beams, floodwalls) to stop floodwater from entering your home.
• Seal walls in basements with waterproofing compounds to avoid seepage.
• If a flood is likely in your area, listen to the radio or television for information.
• Know the difference between a flood watch and a flood warning. A watch means flooding is possible. A warning means flooding is occurring or will occur soon.
When a Flood Is Imminent
• Be prepared! Pack a bag with important items in case you need to evacuate. Don't forget to include needed medications.
• If advised to evacuate your home, do so immediately.
• If there is any possibility of a flash flood, move immediately to higher ground.
• If possible, bring in outdoor furniture and move essential items to an upper floor.
• Turn off utilities at the main switches or valves if instructed to do so. Disconnect electrical appliances.
During a Flood
• Do not walk through moving water. As little as 6 inches (15 centimeters) of moving water can make you fall.
• If you have to walk in water, wherever possible, walk where the water is not moving. Use a stick to check the firmness of the ground in front of you.
• Do not drive into flooded areas. If floodwaters rise around your car, abandon the car and move to higher ground if you can do so safely.
• Do not touch electrical equipment if you are wet or standing in water.
After a Flood
• Listen for news reports to learn whether the community's water supply is safe to drink.
• Avoid floodwaters; water may be contaminated by oil, gasoline, or raw sewage. Water may also be electrically charged from underground or downed power lines.
• Avoid moving water.
• Be aware of areas where floodwaters have receded. Roads may have weakened and could collapse under the weight of a car.
• Stay away from downed power lines, and report them to the power company.
• Return home only when authorities indicate it is safe.
• Stay out of any building if it is surrounded by floodwaters.
• Service damaged septic tanks, cesspools, pits, and leaching systems as soon as possible. Damaged sewage systems are serious health hazards.
• Clean and disinfect everything that got wet. Mud left from floodwater can contain sewage and chemicals.
