In all special flood hazard areas, the following provisions are required:
(A) All new construction and substantial improvements must be designed (or modified) and adequately anchored to prevent flotation, collapse, and lateral movement of the structure;
(B) All new construction and substantial improvements must 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; and
(D) All new electrical, heating, ventilation, plumbing, air conditioning, and other service equipment shall be located at or above the RFPE, 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, water heaters, and electric outlets/switches.
(1) Replacements that are part of a substantial improvement, electrical, heating, ventilation, plumbing, air conditioning equipment, and other service equipment must 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 the requirements for the original structure.
(E) All new and replacement water supply systems must be designed to minimize or eliminate the infiltration of floodwaters into the system.
(F) New and replacement sanitary sewage systems must be designed to minimize or eliminate the infiltration of floodwaters into the systems, and discharges from the systems into floodwaters.
(G) On-site waste disposal systems shall be located and constructed to avoid impairment to them, or contamination from them, during flooding.
(H) Nothing in this chapter will prevent the repair, reconstruction, or replacement of a building or structure existing on the effective date of this chapter, 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, non-encroachment area, or stream setback, and provided that such repair, reconstruction or replacement meets all of the other requirements of this chapter.
(I) New solid waste disposal facilities and sites, hazardous waste management facilities, salvage yards, and chemical storage facilities will not be permitted, except by variance as specified in § 150.054(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 § 150.051(C).
(J) All subdivision proposals and other development proposals must be consistent with the need to minimize flood damage.
(K) All subdivision proposals and other development proposals must have public utilities and facilities, such as sewer, gas, electrical and water systems, located and constructed to minimize flood damage.
(L) All subdivision proposals and other development proposals will have adequate drainage provided to reduce exposure to flood hazards.
(M) All subdivision proposals and other development proposals must have received all necessary permits from those governmental agencies for which approval is required by federal or state law, including § 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1334.
(N) When a structure is partially located in a special flood hazard area, the entire structure must meet the requirements for new construction and substantial improvements.
(O) 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 risk zone and the highest BFE will apply.
