Proper Use of Sandbags

Quick Storm Preparation Tips
  • Check roof drains and down spouts to make sure they are clear of debris.
  • Keep children away from creeks and large drains which can be deadly during storms.
  • Keep leaves and yard trimmings out of storm drains and gutters.
  • Don't forget your pets, and don’t forget to pick up pet waste to prevent water pollution.
  • Turn off automatic sprinklers.
  • Don't store hazardous materials in areas that may be subject to flooding.
  • Store emergency supplies (first aid kit, essential medicines, cash, food, non-electric can opener, portable battery-operated radio, flashlights and spare batteries) in air-tight bags and in handy locations.
  • Keep your car fueled/charged. If electric power is cut off, filling stations may not be able to operate.
  • Clean and clear creek/channel/storm drainage systems on your property.
