Flood Precautions

Post Hurricane/Tropical Storm Flood Precautions
Due to heavy rains that may be created by hurricanes and tropical storms, properties located in low-lying areas or near surface waterways may become flooded. For those properties served by private water supplies, these wells may become covered by floodwater. This condition poses a public health hazard. Wells inundated by floodwater may be contaminated and should not be used until tested. Also, floodwaters can create public health and safety hazards as well as property damage. For information regarding water disinfection and floodwater clean-up procedures and safety precautions, please access the information below:
  • Do not allow children to play in or near floodwater or storm drains.
  • Disinfect all furniture, woodwork and other household surfaces in homes that have flooded.
  • Wash hands frequently during cleanup to lessen recontamination of cleaned areas.
  • To prevent allergic reactions and other health problems caused by mold, replace porous wallboard (from at least 12 inches above the waterline) that has been flood-damaged.
  • Disinfect children's toys with a solution of one cup bleach to five gallons of water.
  • Try to rest and conserve energy. Persons with heart conditions and other illnesses should avoid strenuous exertion. 
  • Remain calm. Signs of anger and depression are normal under catastrophic conditions. Sensitivity to the stress felt by others can help restore their calm.
  • Return home in daylight for best visibility and to avoid using unsafe power sources. 
  • Standing water after floods is a breeding place for mosquitoes. Drain all standing water and empty water from outdoor items such as old tires, cans and flower pot bases. Protect yourself with an appropriate insect repellent. 
  • Let no one re-enter your home while flooded unless the main electrical switch has been turned off.
  • Wear shoes in post-flood areas to reduce the chances of punctures or cuts from nails and other sharp contaminated objects.
