Flood Safety Tips

Be sure to follow these important flood safety rules to reduce personal risk during a flood:

  • Don’t drive through a flooded area. More people drown in cars than anywhere else. The water depth and road condition are always unknown. Vehicles can be swept away in only 12 inches of water.
  • Don’t walk through flood waters. Flood currents are also deceptive. Adults can be swept off their feet in only 6 inches of water.
  • Avoid electrical lines and equipment. Electrocution is the second leading cause of death during floods. Turn off power at your service panel. Electrical current will travel through flood water.
  • Be alert to gas leaks. Turn off gas to your house before a flood. If you smell gas, report it to your gas company and avoid open flames.
  • Don’t use gas engines or fires indoors during power outages. These pose risk of carbon monoxide poisoning and house fires.
  • Clean anything that has been wet. Flood water will be contaminated with sewage, oil, gasoline, and a variety of chemicals that pose severe health risks.
  • Always cooperate with emergency officials and rescue personnel. You can replace personal belongings, but you can't replace someone's life.

Floodplain Administration & Management

Floodplain management is the operation of a community program of preventive and corrective measures to reduce the risk of current and future flooding, resulting in a more resilient community. These measures take a variety of forms, are carried out by multiple stakeholders with a vested interest in responsible floodplain management, and generally include requirements for zoning, subdivision or building, building codes and special-purpose floodplain ordinances.

Please visit Missoula County's Floodplain Administration website for detailed floodplain information, including maps, current regulations, permit applications and more.
