Protecting Your Home > Elevation

 

Elevation means raising the structure above the flood level.

  • This method is generally viewed as the best way to mitigate, short of removing the structure.
  • Elevation is easiest and less costly for houses on posts/piles or crawlspaces. It is possible to elevate a slab house, but it is more difficult and costs more.
  • Elevated buildings get lower flood insurance rates.

Posts/Piles:

  • Most of the cost is in the setup and foundation construction, rather than in materials
  • Funding options are available through FEMA programs and the U. S. Army Corps of Engineers
  • Less disruptive because lifting equipment can be placed under the house

Crawlspace:

  • Most of the cost is in the setup and foundation construction, rather than in materials
  • Appropriately sized vents are necessary - one square inch for each square foot of the building's footprint
  • Less disruptive because lifting equipment can be placed under the house

Slab:

  • Most costly and disruptive
  • Can cost up to $100,000
