In all SFHAs and known flood prone areas the following provisions are required:
(A) New construction and substantial improvements shall be anchored to prevent flotation, collapse or lateral movement of the structure;
(B) Manufactured homes shall be anchored to prevent flotation, collapse, or lateral movement.

(E) Electrical, heating, ventilation, plumbing, air conditioning equipment, utility meters, and other service facilities shall be located at/above the FPG or designed so as to prevent water from entering or accumulating within the components below the FPG. Water and sewer pipes, electrical and telephone lines, submersible pumps, and other waterproofed service facilities may be located below the FPG;
(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 system;
(H) On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding;
