Floodplain Development Permits and Elevation Certificates in Florida

In a flood zone, the building permit is not the only permit. A separate floodplain development permit governs almost any change to the land, and an elevation certificate proves the finished building sits where it should. Endless Life Design carries both through the local floodplain office, from application to closeout.

Why Choose Endless Life Design
THE LOCAL FLOODPLAIN DEVELOPMENT PERMIT
Every community in the National Flood Insurance Program must adopt a floodplain management ordinance and require a floodplain development permit before any development begins in a Special Flood Hazard Area. The local floodplain administrator reviews and issues it, separately from — and often alongside — the building permit.
WHAT COUNTS AS DEVELOPMENT
Under the federal definition the program uses, development is any man-made change to the land — not only buildings, but filling, grading, paving, excavation, drilling, pile driving, dredging, land clearing, and the permanent storage of materials. Because it reaches activities the Florida Building Code does not, the floodplain permit is sometimes the primary approval for site work.
THE FLOODWAY AND THE NO-RISE RULE
The floodway is the channel that must stay clear to carry floodwater. Encroachments such as fill, structures, and substantial improvements are prohibited there unless a registered engineer's hydrologic and hydraulic analysis demonstrates that the work causes no rise in the base flood elevation.
THE ELEVATION CERTIFICATE
The elevation certificate is the FEMA form, completed by a licensed surveyor, engineer, or architect, that documents the elevation of a building's lowest floor relative to the base flood elevation. The floodplain administrator uses it to confirm that a finished building actually meets the elevation the permit required.
THE CERTIFICATE'S ROLE AFTER RISK RATING 2.0
Since Risk Rating 2.0 took full effect, the elevation certificate is no longer required to rate most flood insurance policies, because FEMA now uses modeled data. It remains required by local floodplain ordinances for permitting and compliance, and an owner may still submit one voluntarily to lower a premium when the building sits higher than the model assumes.
MAP CHANGES AND FINAL CLOSEOUT
Where a project changes the flood picture — building on fill, or revising mapped elevations — FEMA issues a Letter of Map Amendment or a Letter of Map Revision. The certificate of occupancy is commonly withheld until the as-built elevation certificate, and any required map revision, confirm that the finished work complies.
COUNTY AND MUNICIPALITY INSPECTION COMMENTS FOR PERMIT APPROVAL
Common comments include:
Site work begun in the flood zone without a floodplain development permit.
Floodway encroachment without a no-rise analysis.
No as-built elevation certificate provided at closeout.
Finished-floor elevation below the elevation the permit required.
Permanent storage or fill placed in the Special Flood Hazard Area without authorization.
