A registered professional engineer or architect shall develop and review structural design, specifications and plans for the construction and shall certify that the design and methods of construction are in accordance with accepted standards of practice as outlined in this subsection. A record of the certification, which includes the specific elevation in relation to mean sea level to which the structures are floodproofed, shall be maintained by the Floodplain Administrator.
