The 5-foot elevation

  • Easier access, shorter staircases
  • Slightly lower cost to design and construct the new foundation and supports
  • Limited usefulness of under-slab space
  • Wheelchair access requires 60-foot ramp, chair lift or porch lift

The 8-foot elevation

  • Higher level of flood protection
  • Slightly higher cost to design and construct the new foundation and supports
  • Useful under-slab space
  • Larger reduction in flood insurance costs
  • Wheelchair access: elevator or 96-foot ramp

The final elevation of your home or business may be set by building codes, subdivision covenants or engineering limitations. If you have a range of elevation options, your decision can be based on appearance of the elevated structure, how well a certain elevation will fit into the surrounding development or one of the factors mentioned above.

Note: Floodplain regulations prohibit the full enclosure of space below the base flood elevation (BFE) and the conversion of that area to habitable space.
