The evaluation shall be prepared by a qualified North Carolina licensed engineer using standard engineering methods and models. F LOOR A REA The sum of the gross horizontal areas of each floor of the principal building and any accessory buildings or structures, measured from the exterior walls or from the centerline of party walls.

F REEBOARD The height added to the Base Flood Elevation (BFE) or the Future Conditions Flood Elevation to account for the many unknown factors that could contribute to flood heights greater that the height calculated for a selected size flood and floodway conditions, such as wave action, bridge openings, and the hydrological effect of urbanization on the watershed. The Base Flood Elevation plus the freeboard establishes the “Regulatory Flood Protection Elevation.”
