In all areas of special flood hazards, whether the property is located in whole or partly in a flood prone area, the following provisions are required for all new construction and substantial improvements.
(A) All new construction or substantial improvements shall be designed or modified and adequately anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy.
(B) All new construction or substantial improvements within a designated special flood hazard area as per the FEMA FIRM map, shall provide an elevation certificate showing base floor elevations. Construction will require a final elevation certificate as per § 153.26.
(B) All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage. All new construction or substantial improvements of any structure shall have the lowest floor, including basement, elevated at least 24 inches, two feet, above the base flood elevation. Failure to elevate at least 24 inches, two feet, above the highest adjacent grade in a designated flood zone, may result in higher insurance rates.
(C) All new construction or substantial improvements shall be constructed with materials resistant to flood damage.
(D) All new construction or substantial improvements shall be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
(E) All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.
(F) New and replacement sanitary sewage systems shall be designed to minimize or eliminate infiltration of flood waters into the system and discharge from the systems into flood waters.
(G) On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.
