In all areas of special flood hazard, the following provisions are required.
(A) New construction and substantial improvements shall be anchored to prevent flotation, collapse and lateral movement of the structure.
(B) Manufactured homes shall be installed using methods and practices that minimize flood damage. They must be elevated and anchored to prevent flotation, collapse and lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state and local anchoring requirements for resisting wind forces.
(C) New construction and substantial improvements shall be constructed with materials and utility equipment resistant to flood damage.
(D) New construction and substantial improvements shall be constructed by methods and practices that minimize flood damage.
(E) All electrical, heating, ventilation, plumbing, air conditioning equipment and other service facilities shall be designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
(F) New and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.
(G) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters.
(H) On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding.
(I) Any alteration, repair, reconstruction or improvements to a building that is in compliance with the provisions of this chapter, shall meet the requirements of new construction, as contained in this chapter.
(J) Any alteration, repair, reconstruction or improvements to a building that is not in compliance with the provision of this chapter shall be undertaken only if said non-conformity is not further extended or replaced.
(K) All new construction and substantial improvement proposals shall provide copies of all necessary federal and state permits, including § 404 of the Federal Water Pollution Control Act amendments of 1972, 33 U.S.C. § 1344.
(L) All subdivision proposals and other proposed new development proposals shall meet the standards of § 153.41 of this chapter.
(M) When proposed new construction and substantial improvements are partially located in an area of special flood hazard, the entire structure shall meet the standards for new construction.
(N) When proposed new construction and substantial improvements are located in multiple flood hazard risk zones or in a flood hazard risk zone with multiple base flood elevations, the entire structure shall meet the standards for the most hazardous flood hazard risk zone and the highest base flood elevation.
