Summary
Cabarrus County requires new and substantially improved homes in a Special Flood Hazard Area to sit at the Regulatory Flood Protection Elevation, the Base Flood Elevation plus a two-foot freeboard, under Chapter 16 of the Development Ordinance. Where no BFE has been set, the floor must clear the highest adjacent grade by two feet.
Freeboard means the height added to the BFE to account for the many unknown factors that could contribute to flood heights greater than the height calculated for a selected size flood and floodway conditions, such as wave action, blockage of bridge or culvert openings, and the hydrological effect of urbanization of the watershed. The BFE plus the freeboard establishes the Regulatory Flood Protection Elevation. The freeboard for Cabarrus County is a minimum of 2 feet. ... Residential Construction. New construction and substantial improvement of any residential structure (including manufactured homes) shall have the reference level, including basement, elevated no lower than the Regulatory Flood Protection Elevation, as defined in Part 2 of this ordinance.
Full Breakdown
" Part 5, Section B(1) applies that standard directly: new construction and substantial improvement of any residential structure, including manufactured homes, must have its reference level, including any basement, elevated no lower than the Regulatory Flood Protection Elevation. Section B(2) extends the same elevation floor to commercial, industrial and other non-residential construction, though it allows floodproofing to that elevation in Zone AE in lieu of elevation, provided a registered professional engineer or architect certifies that the structure is watertight and can resist hydrostatic and hydrodynamic loads and buoyancy.
Where no BFE has been established for a mapped Special Flood Hazard Area, Part 2 sets the floor at least 2 feet above the highest adjacent grade. The Floodplain Administrator, who is the Zoning Administrator or a designee, verifies elevation certificates as part of Part 4 permit review before occupancy is allowed.
Violations & Fines
Building or substantially improving a structure below the Regulatory Flood Protection Elevation without an approved Floodplain Development Permit is a Class 1 misdemeanor under N.C.G.S. § 143-215.58, carrying a fine up to $100.00, up to thirty days imprisonment, or both, with each day counted as a separate offense.
