Flood Protection Tips for Associations

The increased severity of tropical storm events and shifting rainfall patterns pose many challenges. Whenever the volume of water on land overcomes the capacity of natural and built drainage systems to carry it away, flooding can result. But steps can be taken to mitigate some of the damage caused by flooding.

The following is not an all-inclusive list but a kick start for your community to begin planning and budgeting for future mitigation projects.

  • Drainage Systems – Aging and overloaded stormwater systems can be updated to allow water to be moved, stored, and drained more efficiently.
  • Gutters – Removing leaves and other debris from clogged gutters and downspouts can prevent water from pooling around a building’s foundation. Be sure to locate the down spout in the proper direction. A down spout should never directly discharge into a canal or other water body but instead be directed to grassed or rocked areas that will allow the stormwater to slowly seep into the ground.
  • Building Exteriors – A form of “dry flood-proofing,” the application of painted coatings and sealants that you apply to your foundation, walls, windows and doorways will help prevent flood water from leaking into your structure through cracks or penetrations where utilities may come through.
  • Re-grading Property– Adjusting the slope (grade) around a building’s foundation can help stormwater flow more easily away from the building and toward drainage systems like street drains or swale areas. Re-grading may be especially effective for older communities where the grade may have settled over time or been modified by landscaping.
  • Raising Building Systems – HVAC systems and electric panels raised or relocated to above flood levels can prevent future damage to expensive systems.
  • Permeable Pavement – Permeable pavement is a type of paving material that is highly pervious and allows rainwater to pass through it, which reduces runoff. By reducing runoff, permeable pavement manages stormwater and decreases flood risk.
  • Rain Gardens -This type of green infrastructure is designed and built to mitigate stormwater flooding. A rain garden is a garden in a depressed area of a landscape that is designed to temporarily hold and soak in rainwater while providing a pleasing look to the landscape.
