Flood

Massive flooding continues to hit Colorado Floods typically occur between April in October in Boulder County and impact areas along streams and rivers, canyons, ditches, and low-lying areas.

Before a flood:

  • Know your neighborhood flood history and low-lying areas.
  • Consider purchasing flood insurance; most homeowner’s policies do not cover damage from rising water. Your insurance agent will have more information about the National Flood Insurance Program (NFIP).
  • Determine if your home and workplace are in a flood plain.
  • Stay alert for changing weather conditions.
  • When conditions indicate the potential for flooding, get out of low-lying areas, canyons and areas downstream from dams.
  • If flooding becomes very likely, consider filling up sinks, bathtubs and other containers with clean water.

During a flood:

  • If you receive a flash flood warning, move to higher ground immediately. If you can evacuate safely and have been instructed to do so, move quickly.
  • If you cannot evacuate safely, go to the highest floor in your house. Take your emergency supplies with you.
  • Do not attempt to cross water that is above your knees.
  • Do not drive over a flooded area or around barricades. Abandon a stalled vehicle and immediately move to higher ground.
  • Avoid moving water – six inches can knock you off your feet, and 18-24 inches can float a car.
  • Avoid standing water – it will likely be contaminated and contain large amounts of debris.

After a flood:

  • Follow the instructions of authorities and obey posted warnings.
  • Wait for officials to determine if the water is safe to drink.
  • Throw away water and food that has come into contact with floodwater.
  • Check for utility outages. Utilities will have to be turned back on by a professional.
  • Continue monitoring radio and television for information on weather and recovery efforts.
  • Consider asking a professional to evaluate your home for mold.
  • Use bleach to clean up – it is effective in killing germs, and can also be used to purify water to drink (10-20 drops of plain bleach per gallon of water).
