Summary
Melbourne requires new and substantially improved buildings in flood hazard areas to elevate their lowest floor to the base flood elevation plus 1.33 feet, a local amendment stricter than the unmodified state floor. Coastal high-hazard V-Zone structures must clear that same 1.33-foot margin at their lowest horizontal structural member.
R322.2.1. Elevation requirements. 1.Buildings and structures in flood hazard areas, including flood hazard areas designated as Coastal A Zones, shall have the lowest floors elevated to or above the base flood elevation plus 1.33 feet or the design flood elevation, whichever is higher.2.In areas of shallow flooding (AO Zones), buildings and structures shall have the lowest floor (including basement) elevated to a height above the highest adjacent grade of not less than the depth number specified in feet on the FIRM plus 1.33 feet, or not less than three feet if a depth number is not specified.3.Basement floors that are below grade on all sides shall be elevated to or above the base flood elevation plus 1.33 feet or the design flood elevation, whichever is higher.

Full Breakdown
Sec. 80(e) of the Melbourne City Code amends the Florida Residential Code's elevation standards. 33 feet or the design flood elevation, whichever is higher. 33-foot standard. 33-foot margin to coastal high-hazard areas and Coastal A Zones, but measures it to the bottom of the lowest horizontal structural member supporting the lowest floor, excludes pilings, pile caps, columns, grade beams and bracing from that measurement, and bans below-grade basements and the use of fill for structural support outright. The same subsection sets the city's wind speed design zones (140 mph Vult for Risk Category I, 150 mph for Risk Category II, and 160 mph for Risk Category III and IV) and places all of Melbourne in the wind-borne debris region.
The building official, acting as floodplain administrator under Sec. 153, reviews permit applications and can require a Florida-licensed surveyor's certification of the lowest floor's elevation at placement and again at final inspection under Sec. 175 and Sec. 176. Variance requests go to the planning and zoning board under Sec. 178 through Sec. 185, which cannot grant relief that would raise flood heights and must warn applicants in writing that federal flood insurance costs run as high as $25 per $100 of coverage when a structure sits below base flood elevation.
Violations & Fines
A building lacking the documentation proving it meets the 1.33-foot freeboard standard is presumed to be in violation until that proof is supplied, under Sec. 13.186. The floodplain administrator can serve a notice of violation or a stop-work order on the owner, agent, or contractor under Sec. 13.187, and anyone who keeps working after being served is subject to penalties under Sec. 1-14 of the City Code per Sec. 13.188.
