AFTER YOUR PERMIT IS ISSUED

For new construction, prior to beginning any vertical work, you will be required to submit a completed Lowest Floor Elevation Form, signed and sealed by a Registered Land Surveyor, Professional Engineer or Registered Architect, and the issued yellow building permit card for review and approval by Floodplain Management staff. When approved, the yellow permit card will be signed and all construction work may resume.

Also, for new construction, you will be required to submit a completed Elevation Certificate or Dry Flood-proofing Certificate signed and sealed by a Registered Land Surveyor, Professional Engineer or Registered Architect and the issued yellow building permit card for review and approval by Floodplain Management Staff just prior to receiving final building inspection approval. When approved, the yellow building permit card will be signed and final building inspection may proceed. For requirements on all other construction or development types, please contact Floodplain Management Staff.

SERVICES

Floodplain Management and Disaster Mitigation Staff can review and advise property owners’ regarding floodproofing plans for their properties.  FEMA also offers a more in-depth  guide to several retrofitting techniques. This guide describes six retrofitting methods for you to consider as you think about how to protect your home from flooding:

  • Elevation – Raising your home so that the lowest floor or lowest horizontal member is at or above the regulated flood level. You can accomplish this in several ways.
  • Relocation – Moving your home to higher ground where it will reduce the exposure to flooding.
  • Demolition – Tearing down your damaged home and either rebuilding on the same property or buying or building a home elsewhere.
  • Wet Floodproofing – Making portions of your home resistant to flood damage and allowing water to enter during flooding.
  • Dry Floodproofing – Sealing your home to prevent floodwaters from entering.
  • Barrier Systems – Building a floodwall or levee around your home to restrain floodwaters.
