Natural Disasters/Flash Flood


  • Follow best practices if you must build in a floodplain.[1]
  • If there is adequate time before rainfall during a flash flood warning, evacuate to a safe area.[2]


  • Flood water can be deceptive! It is difficult to determine the depth or speed of floodwater.[3]
  • Do not attempt to cross floodwater in an automobile
    • Even shallow water can disable or carry away heavy vehicles such as trucks.[3]
    • If you do find yourself in a automobile which is being carried away by floodwater, abandon it immediately - It is a lost cause.[4]
  • Do not directly touch floodwater if possible.[4] Floodwater is rarely pure and may contain contaminants such as sewage, chemicals, electical hazards, or sharp debris.[5] Because flood water is often murky, you may not be able to truly see what hazards are in the water.
