§ 151.25 GENERAL CONSTRUCTION STANDARDS.
   In all special flood hazard areas, the following provisions are required:
   (A)   All new construction and substantial improvements shall be adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;
   (B)   Manufactured homes shall be anchored to prevent flotation, collapse, or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This standard shall be in addition to and consistent with applicable commonwealth requirements for resisting wind forces;
   (C)   All 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)   Electrical, heating, ventilation, plumbing, air condition 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)   Within Zones AH or AO, so that there are adequate drainage paths around structures on slopes to guide floodwaters around and away from proposed structures;
   (G)   New and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system;
   (H)   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 floodwaters;
   (I)   On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding;
   (J)   Any alteration, repair, reconstruction, or improvements to a structure, which is not in compliance with the provisions of this chapter shall meet the requirements of new construction as contained in this chapter; and
   (K)   Any alteration, repair, reconstruction, or improvements to a structure, which is not in compliance with the provisions of this chapter, shall be undertaken only if said nonconformity is not furthered, extended, or replaced.
