(2) All new buildings must be constructed on foundations that are approved by a licensed professional engineer.
(D) All new electrical, heating, ventilation, plumbing, air conditioning equipment and other service facilities 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.
