Water load- ing values used shall be those associat- ed with the base flood. Wind loading values used shall be those required by applicable State or local building standardso A registered professional engineer or architect shall develOP or review the structural design. specifica~ tlonS and plans for the construction, and shall certify that the design and methods of construction to be used are in accordance with accepted standards of pmctlce for meeting the provisiOns of paragraphs (e)(4)(I) and (Ill of this section.

For the purposes of this section, a breakway wall shall have a design safe loading resistance of not less than 10 and no more than 20 pounds per square foot. Use of breakway walls which exceed a design sa.fe loading resistance of 20 pounds per square foot (elt,her by design or when so required by local or State codes) may be pennltted only If a registered professional engineer or architect certifies that the designs ~60.3 proposed meet the following condi- tions: (i) BI'eakaway wall collapse shall result from a water load less than that which would occur during the blloSe flood; and. (II) The 'elevated portion of the building and supporting foundation system shall not be subject to collapse, displacement, or other structural damage due to the effects of wind and water loads acting simultaneously on all building components (~tructural and non-structural), Water loading values used shall be those associated with the blloSe flood. Wind loading values used shall be those required by applicable State or local building standards. Such enclosed space shall be useable solely for parking of vehicles. building access. or storage. (6) Prohibit the use of fll1 for struc- tural support of buildings within Zones VI-30, VE, and V on the com- munity's FIRM; (7) Prohibit man-made alteration oj sand dunes and mangrove stand:: within Zones Vl-30, VE, and V on thE commwllty's FIRM which would In, crelloSe potential flood damage.
