Before a Flood – Be Aware

According to FEMA, to prepare for a flood, you should:

  • Avoid building in a floodprone area unless you elevate and reinforce your home.
  • Elevate the furnace, water heater, and electric panel if susceptible to flooding.
  • Install "check valves" in sewer traps to prevent floodwater from backing up into the drains of your home.
  • Contact community officials to find out if they are planning to construct barriers (levees, beams, floodwalls) to stop floodwater from entering the homes in your area.
  • Seal the walls in your basement with waterproofing compounds to avoid seepage.

During a Flood – Be Safe

According to FEMA, if a flood is likely in your area, you should:

  • Listen to the radio or television for information.
  • Be aware that flash flooding can occur. If there is any possibility of a flash flood, move immediately to higher ground. Do not wait for instructions to move.
  • Be aware of streams, drainage channels, canyons, and other areas known to flood suddenly. Flash floods can occur in these areas with or without such typical warnings as rain clouds or heavy rain.

If you must prepare to evacuate, you should do the following:

  • Secure your home. If you have time, bring in outdoor furniture. Move essential items to an upper floor.
  • Turn off utilities at the main switches or valves if instructed to do so. Disconnect electrical appliances. Do not touch electrical equipment if you are wet or standing in water.

If you have to leave your home, remember these evacuation tips:

  • Do not walk through moving water. Six inches of moving water can make you fall. If you have to walk in water, 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. You and the vehicle can be quickly swept away.

Driving Flood Facts

The following are important points to remember when driving in flood conditions:

  • Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling.
  • A foot of water will float many vehicles.
  • Two feet of rushing water can carry away most vehicles including sport utility vehicles (SUV’s) and pick-ups.

After a Flood – Be Smart

According to FEMA, the following are guidelines should be used for the period following 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.
  • Use extreme caution when entering buildings; there may be hidden damage, particularly in foundations.
  • 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.

When returning home – FEMA offers the following advice:

Don't return to your flood-damaged home before the area is declared to be safe by local officials. Returning home can be both physically and mentally challenging. Above all, use caution.

Check for injuries. Do not attempt to move seriously injured persons unless they are in immediate danger of death or further injury. If you must move an unconscious person, first stabilize the neck and back, then call for help immediately.

  • Keep a battery-powered radio with you so you can listen for emergency updates and news reports.
  • Use a battery-powered flash light to inspect a damaged home.
  • Note: The flashlight should be turned on outside before entering - the battery may produce a spark that could ignite leaking gas, if present.
  • Watch out for animals, especially poisonous snakes. Use a stick to poke through debris.
  • Be wary of wildlife and other animals
  • Use the phone only to report life-threatening emergencies.
  • Stay off the streets. If you must go out, watch for fallen objects; downed electrical wires; and weakened walls, bridges, roads, and sidewalks.

Before You Enter Your Home

Walk carefully around the outside and check for loose power lines, gas leaks, and structural damage. If you have any doubts about safety, have your residence inspected by a qualified building inspector or structural engineer before entering. Do not enter if:

  • You smell gas.
  • Floodwaters remain around the building.
  • Your home was damaged by fire and the authorities have not declared it safe.

Going Inside Your Home

When you go inside your home, there are certain things you should and should not do. Enter the home carefully and check for damage. Be aware of loose boards and slippery floors. The following items are other things to check inside your home:

  • Natural gas. If you smell gas or hear a hissing or blowing sound, open a window and leave immediately. Turn off the main gas valve from the outside, if you can. Call the gas company from a neighbor’s residence. If you shut off the gas supply at the main valve, you will need a professional to turn it back on. Do not smoke or use oil, gas lanterns, candles, or torches for lighting inside a damaged home until you are sure there is no leaking gas or other flammable materials present.
  • Sparks, broken or frayed wires. Check the electrical system unless you are wet, standing in water, or unsure of your safety. If possible, turn off the electricity at the main fuse box or circuit breaker. If the situation is unsafe, leave the building and call for help. Do not turn on the lights until you are sure they’re safe to use. You may want to have an electrician inspect your wiring.
  • Roof, foundation, and chimney cracks. If it looks like the building may collapse, leave immediately.
  • Appliances. If appliances are wet, turn off the electricity at the main fuse box or circuit breaker. Then, unplug appliances and let them dry out. Have appliances checked by a professional before using them again. Also, have the electrical system checked by an electrician before turning the power back on.
  • Water and sewage systems. If pipes are damaged, turn off the main water valve. Check with local authorities before using any water; the water could be contaminated. Pump out wells and have the water tested by authorities before drinking. Do not flush toilets until you know that sewage lines are intact.
  • Food and other supplies. Throw out all food and other supplies that you suspect may have become contaminated or come in to contact with floodwater. Your basement. If your basement has flooded, pump it out gradually (about one third of the water per day) to avoid damage. The walls may collapse and the floor may buckle if the basement is pumped out while the surrounding ground is still waterlogged.
  • Open cabinets. Be alert for objects that may fall.
  • Clean up household chemical spills. Disinfect items that may have been contaminated by raw sewage, bacteria, or chemicals. Also clean salvageable items.
  • Call your insurance agent. Take pictures of damages. Keep good records of repair and cleaning costs.

Removing Mold from Your Home

FEMA advises that when dealing with mold and mildew in your flood damaged home after natural disasters such as hurricanes, tornadoes, and floods, excess moisture and standing water contribute to the growth of mold in homes and other buildings.

Be aware that mold may be present and may be a health risk for your family, if your home has water damage due to:

  • Flooding,
  • Sewage back-up,
  • Plumbing or roof leaks,
  • Damp basements or crawl space,
  • Overflows from sinks or bathtub, or
  • High humidity: steam cooking, dryer vents, humidifiers.

The U.S. Environmental Protection Agency website contains information on mold cleanup and remediation in homes, schools and other large commercial buildings.

The Centers for Disease Control and Prevention website includes general background information about mold health hazards and mold safety recommendations.
