(B) All official boards and commissions of the town shall take into account flood and flood related erosion hazards to the extent that they are known, in all official actions relating to land management and use.
(C) The Building official shall obtain, review and reasonably utilize any base flood (100-year flood) elevation data from federal, state or other sources. Such information shall be made available to the Planning and Zoning Commission.
(D) Before issuing a permit for new construction within A Zones on the FHBM or FIRM, the Building Official shall review the permit application to determine that all new construction and substantial improvements (including the placement of prefabricated buildings and mobile homes) shall:
(1) Be designed (or modified) and adequately anchored to prevent flotation, collapse or lateral movement of the structure;
(2) Be constructed with materials and utility equipment resistant to flood damage; and
(3) Be constructed by methods and practices that minimize flood damage.
(E) Before issuing a permit for new construction or substantial improvement of residential structures within A Zones on the FHBM or FIRM, the Building Official shall require that the lowest floor (including the basement) be elevated to or above the base flood level.

(b) Together with attendant utility and sanitary facilities, be designed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy.
(2) Where such flood proofing is utilized, a registered professional engineer or architect shall certify that the flood-proofing methods are adequate to withstand loads and forces associated with the base flood and a record of such certification shall be maintained by the Building Official.
(G) The Building Official shall:
(1) Obtain the elevation of all new or substantially improved structures within A Zones on the FHBM or FIRM and whether or not such structures contain a basement;
