In all special flood hazard areas the following provisions are required:
(A) All new construction and substantial improvements shall be designed (or modified) and adequately anchored to prevent flotation, collapse, and lateral movement of the structure.
(B) All new construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage in accordance with the FEMA Technical Bulletin 2, Flood Damage Resistant Materials Requirements.
(C) All new construction and substantial improvements shall be constructed by methods and practices that minimize flood damages.
(D) All new electrical, heating, ventilation, plumbing, air conditioning equipment, and other service facilities equipment shall be located at or above regulatory flood protection elevation or designed and installed to prevent water from entering or accumulating within the components during the occurrence of the base flood These include, but are not limited to, HVAC equipment, water softener units, bath/kitchen fixtures, ductwork, electric/gas meter panels/boxes, utility/cable boxes, appliances (washers, dryers, refrigerators, freezers, etc.), hot water heaters, and electric outlets/switches.
(1) Replacements part of a substantial improvement, electrical, heating, ventilation, plumbing, air conditioning equipment, and other service equipment shall also meet the above provisions.
(2) Replacements that are for maintenance and not part of a substantial improvement, may be installed at the original location provided the addition and/or improvements only comply with the standards for new construction consistent with the code and requirements for the original structure.
(E) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system.
(F) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into flood waters.
(G) On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding.
(H) Any alteration, repair, reconstruction, or improvements to a structure, which is in compliance with the provisions of this chapter, shall meet the requirements of new construction as contained in this chapter.
(I) Nothing in this ordinance shall prevent the repair, reconstruction, or replacement of a building or structure existing on the effective date of this ordinance and located totally or partially within the floodway, non-encroachment area, or stream setback, provided there is no additional encroachment below the Regulatory Flood Protection Elevation in the floodway, nonencroachment area, or stream setback, and provided that such repair, reconstruction, or replacement meets all of the other requirements of this ordinance; and provided that if possible, the building or structure be re-located outside the floodway or non-encroachment area.
(J) New solid waste disposal facilities and sites, hazardous waste management facilities, salvage yards, and chemical storage facilities shall not be permitted, except by variance as specified in § 151.29 (J). A structure or tank for chemical or fuel storage incidental to an allowed use or to the operation of a water treatment plant or wastewater treatment facility may be located in a Special Flood Hazard Area only if the structure or tank is either elevated or floodproofed to at least the Regulatory Flood Protection Elevation and certified in accordance with the provisions of § 151.26 (C).
(K) All subdivision proposals and other development proposals shall be consistent with the need to minimize flood damage.
(L) All subdivision proposals and other development proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage.
(M) All subdivision proposals and other development proposals shall have adequate drainage provided to reduce exposure to flood hazards.
(N) All subdivision proposals and other development proposals shall have received all necessary permits from those governmental agencies for which approval is required by federal or state law, including Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1334.
(O) Base flood elevation data shall be provided for each lot in all subdivision proposals and delineated accurately on preliminary and final plats. Recorded plats should contain a disclaimer statement stipulating that if base flood elevation data is revised in the future, the revisions, if more stringent, may take precedence over those displayed on the plat. Flood hazard boundary map numbers and dates shall be displayed on the plat.
(P) All new subdivisions shall, if possible, have access roads located outside the 100-year floodplain. All roads within the 100-year floodplain shall be pre-approved by the NC Emergency Management Floodplain Mapping Division and engineered and constructed to minimize flood damage.
(Q) No fill material will be placed in the SFHA expect for limited construction purposes (e.g. to backfill a structure or cover a septic system placement), or for engineered roads and bridges.
(R) When a structure is partially located in a special flood hazard area, the entire structure shall meet the requirements for new construction and substantial improvements.
(S) When a structure is located in multiple flood hazard zones or in a flood hazard risk zone with multiple base flood elevations, the provisions for the more restrictive flood hazard zone and the highest base flood elevation shall apply.
