Summary
Before building anything in a Columbia County flood hazard area, owners must first get a floodplain development permit under LDR Sec. 8.4.1, then certify the lowest floor's elevation to the floodplain administrator once it's placed, under Sec. 8.6.4, before construction can go any higher.
8.4.1Permits required. Any owner or owner's authorized agent (hereinafter "applicant") who intends to undertake any development activity within the scope of this ordinance ... which is wholly within or partially within any flood hazard area shall first make application to the floodplain administrator, and the building official if applicable, and shall obtain the required permit(s) and approval(s). No such permit or approval shall be issued until compliance with the requirements of this ordinance and all other applicable codes and regulations has been satisfied. ... 8.6.4Buildings, structures and facilities exempt from the Florida Building Code, lowest floor inspection. Upon placement of the lowest floor, including basement, and prior to further vertical construction, the owner of a building, structure or facility exempt from the Florida Building Code, or the owner's authorized agent, shall submit to the floodplain administrator:1.If a design flood elevation was used to determine the required elevation of the lowest floor, the certification of elevation of the lowest floor prepared and sealed by a Florida licensed professional surveyor.
Full Breakdown
Section 8.4.1 requires any owner or authorized agent undertaking development, including buildings and facilities exempt from the Florida Building Code, wholly or partly within a flood hazard area to first apply to the floodplain administrator and the building official and obtain the required permits and approvals; no permit issues until the applicant demonstrates compliance with the ordinance and all other applicable codes. That upfront review matters for hurricane readiness because Section 8.5.1 requires site plans to delineate flood hazard areas, floodway boundaries, flood zones, and base flood elevations before a permit is granted.
Once construction reaches the lowest floor, Section 8.6.4 requires the owner or agent to stop and submit certification to the floodplain administrator before any further vertical construction: if a design flood elevation set the required height, a Florida-licensed professional surveyor must certify the lowest floor's elevation. A final certification of that elevation is required again at final inspection under Section 8.6.5. Permits expire if work does not start within 180 days of issuance, or is suspended for 180 days, per Section 8.4.6, and the floodplain administrator can suspend or revoke a permit issued in error or based on incomplete information under Section 8.4.7.
This staged elevation-verification process is how the county keeps homes above flood levels before hurricane season exposes uncertified construction to storm surge and rainfall flooding.
Violations & Fines
Building without the required floodplain development permit, proceeding past the lowest-floor stage without submitting the elevation certification, or continuing after a stop-work order is a violation under Section 8.8; a structure lacking the required elevation documentation is presumed in violation until the documentation is produced, and unlawful continuance after notice carries a fine of not more than $500.00 per day plus costs.
