Floods
Emergency Information
- Flood waters can be extremely dangerous. The force of six inches of swiftly
moving water can knock people off their feet. The best protection during a
flood is to leave the area and go to shelter on higher ground.
- Flash flood waters move at very fast speeds and can roll boulders, tear
out trees, destroy buildings, and obliterate bridges. Walls of water can reach
heights of 10 to 20 feet and generally are accompanied by a deadly cargo of
debris. The best response to any signs of flash flooding is to move immediately
and quickly to higher ground.
- Cars can be easily be swept away in just 2 feet of moving water. If flood
waters rise around a car, it should be abandoned. Passengers should climb
to higher ground.
Danger Zones
Floods and flash floods occur within all 50 states. Communities particularly
at risk are those located in low-lying areas, near water, or downstream from
a dam.
What is a Flood?
Floods are the most common and widespread of all natural disasters--except
fire. Most communities in the United States can experience some kind of flooding
after spring rains, heavy thunderstorms, or winter snow thaws. Floods can be
slow, or fast rising but generally develop over a period of days.
Dam failures are potentially the worst flood events. A dam failure is usually
the result of neglect, poor design, or structural damage caused by a major event
such as an earthquake. When a dam fails, a gigantic quantity of water is suddenly
let loose downstream, destroying anything in its path.
What is a Flash Flood?
Flash floods usually result from intense storms dropping large amounts of rain
within a brief period. Flash floods occur with little or no warning and can
reach full peak in only a few minutes.
Help Your Community Get Ready
The media can raise awareness about floods and flash floods by providing important
information to the community. Here are some suggestions:
- Publish a special section in your local newspaper with emergency information
on floods and flash floods. Localize the information by printing the phone
numbers of local emergency services offices, the American Red Cross, and hospitals.
- Interview local officials about land use management and building codes in
floodplains.
- Work with local emergency services and American Red Cross officials to prepare
special reports for people with mobility impairments on what to do if an evacuation
is ordered.
- Periodically inform your community of local public warning systems.
Did You Know...
- Individuals and business owners can protect themselves from flood losses
by purchasing flood insurance through National Flood Insurance Program. Homeowner's
policies do not cover flood damage. Information is available through local
insurance agents and emergency management offices.
- Flooding has caused the deaths of more than 10,000 people since 1900. Property
damage from flooding now totals over $1 billion each year in the United States.
- More than 2,200 lives were lost as a result of the Johnstown, Pennsylvannia
flood of 1889. This flood was caused by an upstream dam failure.
- On July 31, 1976, the Big Thompson River near Denver overflowed after an
extremely heavy storm. A wall of water 19 feet high roared down the Big Thompson
Canyon where many people were camping. 140 people perished and millions of
dollars of property were lost.
Nobody can stop a flood. But if you are faced with one, there are actions you
can take to protect your family and keep your property losses to a minimum.
Mitigation helps! It lessens the damaging effects from flooding. Participating
in the National Flood Insurance Program (NFIP) and enforcing sound floodplain
management techniques are steps your community can undertake. Constructing barriers
such as levees will also help reduce the amount of damage to your home and crops,
while purchasing flood insurance reduces the financial burden should a flood
or flash flood occur.
The most important thing is to make sure your family is safe.
Before a Flood
What is your flood risk? Your community officials or local emergency management
office are your best resources to learn about the history of flooding for your
region. Ask whether your property is in the floodplain and if it is above or
below the flood stage water level. Flood Insurance Rate Maps (FIRMs) are used
to determine your flood risk. FIRMs are found in several places for your convenience:
- Your local community map repository, usually, the building and planning
departments.
- The FEMA Map Store for maps, flood studies, and other products on-line or
paper copies.
- Call a Map Specialist for specific questions about your flood zone at 1.877.336.2627
Have disaster supplies on hand:
- Flashlights and extra batteries
- Portable, battery-operated radio and extra batteries tuned to a local station,
and follow emergency instructions.
- First aid kit and manual
- Emergency food and bottled water
- Non-electric can opener
- Essential medicines
- Cash and credit cards
- Sturdy shoes
If you live in a frequently flooded area, take preventative measures and stockpile
emergency building materials:
- Plywood, plastic sheeting, lumber, nails, hammer and saw, pry bar, shovels,
and sandbags.
- Have check valves installed in building sewer traps to prevent flood waters
from backing up in sewer drains.
- As a last resort, use large corks or stoppers to plug showers, tubs, or
basins.
Plan and practice an evacuation route.
- Learn flood-warning signs and your community's alert signals
- Contact your local emergency management office or local American Red Cross
chapter for a copy of the community flood evacuation plan.
- This plan should include information on the safest routes to shelters. Individuals
living in flash flood areas should have several alternative routes.
- Request information on preparing for floods and flash floods.
- Develop an emergency communication plan.
- In case family members are separated from one another during floods or flashfloods
(a real possibility during the day when adults are at work and children are
at school), have a plan for getting back together.
- Ask an out-of-state relative or friend to serve as the "family contact."
After a disaster, it's often easier to call long distance. Make sure everyone
in the family knows the name, address, and phone number of the contact person.
- Make sure that all family members know how to respond after a flood or flash
flood.
- Teach all family members how and when to turn off gas, electricity, and
water.
- Teach children how and when to call 911, police, fire department, and
which radio station to tune to for emergency information.
- Be prepared to evacuate.
If Time Permits, Here are Other Steps That You Can Take Before The
Flood Waters Come
- Turn off all utilities at the main power switch and close the main gas valve
if evacuation appears necessary.
- Move valuables, such as papers, furs, jewelry, and clothing to upper floors
or higher elevations.
- Fill bathtubs, sinks and plastic soda bottles with clean water. Sanitize
the sinks and tubs first by using bleach. Rinse, then fill with clean water.
- Bring outdoor possessions, such as lawn furniture, grills and trash cans
inside, or tie them down securely.
Once The Flood Arrives
- Don't drive through a flooded area. If you come upon a flooded road, turn
around and go another way. More people drown in their cars than anywhere else.
- If your car stalls, abandon it immediately and climb to higher ground. Many
deaths have resulted from attempts to move stalled vehicles.
- Don't walk through flooded areas. As little as six inches of moving water
can knock you off your feet.
- Stay away from downed power fines and electrical wires. Electrocution is
another major source of deaths in floods. Electric current passes easily through
water.
- Look out for animals - especially snakes. Animals lose their homes in floods,
too. They may seek shelter in yours.
- If the waters start to rise inside your house before you have evacuated,
retreat to the second floor, the attic, and if necessary, the roof.
- Take dry clothing, a flashlight and a portable radio with you. Then, wait
for help.
- Don't try to swim to safety; wait for rescuers to come to you.
- If Outdoors, climb to high ground and stay there.
After The Flood
Flood dangers do not end when the water begins to recede. Listen to a radio
or television and don't return home until authorities indicate it is safe to
do so.
Remember to help your neighbors who may require special assistance - infants,
elderly people, and people with disabilities.
- If your home, apartment or business has suffered damage, call the insurance
company or agent who handles your flood insurance policy right away to file
a claim.
- Before entering a building, inspect foundations for cracks or other damage.
Don't go in if there is any chance of the building collapsing.
- Upon entering the building, Don't use matches, cigarette lighters or any
other open flames, since gas may be trapped inside. Instead, use a flashlight
to light your way.
- Keep power off until an electrician has inspected your system for safety.
- Floodwaters pick up sewage and chemicals from roads, farms and factories.
If your home has been flooded, protect your family's health by cleaning up
your house right away. Throw out foods and medicines that may have met floodwater.
- Until local authorities proclaim your water supply to be safe, boil water
for drinking and food preparation vigorously for five minutes before using.
- Be careful walking around. After a flood, steps and floors are often slippery
with mud and covered with debris, including nails and broken glass.
- Take steps to reduce your risk of future floods. Make sure to follow local
building codes and ordinances when rebuilding, and use flood-resistant materials
and techniques to protect yourself and your property from future flood damage.
One of the most important things that you can do to protect your home and family
before a flood is to purchase a flood insurance policy. You can obtain one through
your insurance company or agent. Flood insurance is guaranteed through the National
Flood Insurance Program (NFIP),
Your homeowners insurance does not cover flood damage. Don't wait
until a flood is coming to purchase your policy. It normally takes 30 days after
purchase for a flood insurance policy to go into effect.
Inspecting Utilities In A Damaged Home
Check for gas leaks: If you smell gas or hear blowing or hissing noise, open
a window and quickly leave the building. Turn off the gas at the outside main
valve if you can and call the gas company from a neighbor's home. If you turn
off the gas for any reason, it must be turned back on by a professional.
Look for electrical system damage: If you see sparks or broken or frayed wires,
or if you smell hot insulation, turn off the electricity at the main fuse box
or circuit breaker. If you have to step in water to get to the fuse box or circuit
breaker, call an electrician for advice.
Check for sewage and water line damage: If you suspect sewage lines are damaged
avoid using the toilets and call a plumber. If water pipes are damaged, contact
the water company and avoid the water from the tap. You can obtain safe water
by melting ice cubes.
