Summary
New construction and substantial improvements in Deltona flood hazard areas must set the lowest floor at least 12 inches above base flood elevation, or 12 inches above the adjacent road crown if higher, under the city's local freeboard amendment.
All new construction and all substantial improvements to any building shall have the lowest floor, including basement, elevated to no lower than one foot (12 inches) above the base flood elevation. However, if one foot above the base flood elevation height is below the crown of adjacent roads, the lowest floor elevation, including basement, shall be required to be elevated 12 inches above the crown of all adjacent roads, or an average of the finish floor elevations of surrounding homes as determined by the city engineer and building official.

Full Breakdown
Section 90-28 adds a local technical amendment to the Florida Building Code's flood provisions (Section 1612 Building, Section R322 Residential) requiring one extra foot of freeboard beyond FEMA's base flood elevation. All new buildings and substantial improvements in a Deltona flood hazard area must have their lowest floor, including any basement, elevated at least 12 inches above the base flood elevation; where that height would still sit below the crown of the adjacent road, the floor must instead be raised 12 inches above the road crown, or to the average finished floor elevation of surrounding homes as determined by the city engineer and building official. The floodplain administrator and building official jointly enforce the standard.
Violations & Fines
Building or substantially improving a structure below the required 12-inch freeboard elevation violates § 90-28; the floodplain administrator can require correction, and noncompliant construction is treated as a Florida Building Code violation subject to Chapter 105.1 penalties.
