Flood

According to the Colorado Water Conservation Board, floods are the most common and widespread of all natural hazards. Some floods develop more slowly, but flash floods can happen in just minutes. Flood-prone areas have been identified in 267 cities and towns and in all of Colorado’s 64 counties.

Familiarize yourself with these terms to help identify a flood hazard: 

Flood Watch – Flooding is possible. Tune in to NOAA Weather Radio, commercial radio, or television for information.

Flash Flood Watch – Flash flooding is possible. Be prepared to move to higher ground; listen to NOAA Weather Radio, commercial radio, or television for information.

Flood Warning – Flooding is occurring or will occur soon; if advised to evacuate, do so immediately.

Flash Flood Warning – A flash flood is occurring; seek higher ground on foot immediately.

Tips to Minimize Loss of Life and Property in the Event of a Flood
The following tips are from the Federal Emergency Management Agency’s National Flood Insurance Program and should be used as suggested guidelines for action before, during, and after a flood.

Steps to Take Today

    • Make an itemized list of personal property, including furnishings, clothing, and valuables.
    • Take photographs of your home – inside and out are helpful. These will assist and adjuster in settling claims and will help prove uninsured losses, which are tax deductible.
  • Learn the safest route from your home or place of business to high, safe ground if you should have to evacuate in a hurry.
  • Keep a portable radio, emergency cooking equipment, and flashlights in working order.
  • Persons who live in frequently flooded areas should keep on hand materials such as sandbags, plywood, plastic sheeting, and lumber which can be used to protect private property. (Remember, sandbags should not be stacked directly against the outer walls of a building since, when wet, the bags may create added pressure on the foundation.)
  • Buy flood insurance. You should contact your property/casualty agent or broker about eligibility for flood insurance, which is offered through the National Flood Insurance Program. Generally, there is a thirty-day waiting period for this policy to become effective, so don’t wait until the last minute to apply.
  • Keep your insurance policies and a list of personal property in a safe place, such as a safe-deposit box. Know the name and location of the agent(s) who issued the policies.

When the Flood Comes
The safety of your family is the most important consideration. Since flood waters can rise very rapidly, you should be prepared to evacuate before the water level reaches your property.

  • Keep a battery-powered radio tuned to a local station, and follow all emergency instructions.
  • If you’re caught in the house by sudden rising water, move to the second floor and, if necessary, to the roof. Take warm clothing, a flashlight, and a portable radio with you. Then wait for help; don’t try to swim to safety. Rescue teams will be looking for you.
  • When outside the house, remember – floods are deceptive. Try to avoid flooded areas and don’t attempt to walk through floodwaters that are more than knee deep.
  • If and only if, time permits there are several precautionary steps that can be taken.
    • Turn off all utilities at the main power switch and close the main gas valve if evacuation appears necessary.
    • Do not touch any electrical equipment unless it is in a dry area and you are standing on a piece of dry wood while wearing rubber gloves and rubber soled boots or shoes.
    • Move valuable papers, furs, jewelry, clothing, and other contents to upper floors or higher elevations.
    • Fill bathtubs, sinks, and jugs with clean water in case regular supplies are contaminated. You can sanitize these items first by rinsing with bleach.
    • Board up windows or protect them with storm shutters or tape to prevent flying glass.
    • Bring outdoor possessions inside the house or tie them down securely. This includes lawn furniture, garbage cans, tools, signed, and other movable objects that might be swept away or hurled about.
    • If it is safe to evacuate by car, you should consider doing the following:
      • Stock the car with non-perishable foods (like canned goods), a plastic container of water, blankets, first aid kit, flashlights, dry clothing, and any special medication needed by your family.
      • Do not drive where water is over the roads. Parts of the roads may be already washed out.
      • If your car stalls out in a flooded area, abandon it as soon as possible. Floodwaters can rise rapidly and sweep a car (and its occupants) away. Many deaths have resulted from attempts to move stalled vehicles.

After the Flood

  • If your home, apartment, or business has suffered flood damage, immediately call the agent or broker who handles your flood insurance policy. The agent will then submit a loss form to the National Flood Insurance Program. An adjuster will be assigned to inspect your property as soon as possible.
  • Prior to entering a building, check for structural damage. Make sure it is not in danger of collapsing. Turn off any outside gas lines at the meter or tank, and let the house air for several minutes to remove foul odors or escaping gas.
  • Upon entering a building, do not use the open flame as a source of light since gas may still be trapped inside; a battery-operated flashlight is ideal.
  • Watch for electrical shorts or live wires before making certain that the main power switch is turned off. Do not turn on any lights or appliances until an electrician has checked the system for short circuits.
  • Cover broken windows and holes in the roof or walls to prevent further weather damage.
  • Proceed with immediate cleanup measures to prevent any health hazards. Perishable items which pose a health problem should be listed and photographed before discarding. Throw out fresh food and previously opened medicines that have come in contact with flood waters.
  • Water for drinking and food preparation should be boiled vigorously for ten minutes (until the public water system has been declared safe.) Another method of disinfecting is to mix 1/2 teaspoon of liquid commercial bleach with 2-1/2 gallons of water…let stand for five minutes before using. The flat taste can be removed by pouring the water from one container to another or adding a pinch of salt. In an emergency, water may be obtained by draining a hot water tank or melting cubes.
  • Refrigerators, sofas, and other hard goods should be hosed off and kept for the adjuster’s inspection. A good deodorizer when cleaning major kitchen appliances is to add one teaspoon of baking soda to a quart of water. Any partially damaged items should be dried and aired; the adjuster will make recommendations as to their repair or disposal. Take pictures of the damage done to your building and contents.
  • Take all wooden furniture outdoors, but keep it out of direct sunlight to prevent warping. A garage or carport is a good place for drying. Remove drawers and other moving parts as soon as possible, but do not pry open the swollen drawers from the front. Instead, remove the backing and push the drawers out.
  • Shovel out mud while it is still moist to give walls and floors a chance to dry. Once plastered walls have dried, brush off loose dirt. Wash with a mild soap solution and rinse with clean water; always start at the bottom and work up. Ceilings are done last. Special attention at this early stage should also be paid to cleaning out heating and plumbing systems.
  • Mildew can be removed from dry wood with a solution of 4 to 6 tablespoons of tri-sodium phosphate (TSP), 1 cup liquid chlorine bleach, and 1 gallon water.
  • Clean metal at once then wipe with a kerosene-soaked cloth. A light coat of oil will prevent iron from rusting. Scour all utensils, and, if necessary, use fine steel wool on unpolished surfaces. Aluminum may be brightened by scrubbing with a solution of vinegar, cream or tartar, and hot water.
  • Flooded basements should be drained and cleaned as soon as possible. However, structural damage can occur by pumping out the water too quickly. After the flood waters around your property have subsided, begin draining the basement in stages, about 1/3 of the water volume each day.
