,"7 acting simultaneously on all building components. Water loading values used shall be those associated with the base [Iood. Wind loading values used shall be those required by applicable state or local building codes. A registered professional engineer or architect shall develop or review the structural design and methods of construction and shall certify that the proposed design and methods of construction are in accordance with accepted standards. (e) All new construction and substantial mprovements within V 1-30 and V Zones on the Flood Insurance Rate Map shal have the space below the lowest floor either free of obstruction or constructed with non-supporting breakaway walls, open wood lattice-work, or insect screening intended to collapse under wind and water loads without causIng collapse, displacement, or other structural damage to the elevated portion of the building or supporting foundation system. For the purpose of this section, a breakaway wall shall have a design safe loading resistance of not less than ten (10) and no more than twenty (20) pounds per square foot. Use of breakaway wails which exceed a design safeloading resistance of 20 pounds per square foot (either by design or when so required by local or state codes) may be permitted only if a registered professional engineer or architect also certifies that the proposed design also rae, ets the following conditions: (1) Breakaway wall collapse shall result from a water load less than that which would occur during the base flood; and The elevated portion ofthe 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, both structural and non-structural. Water loading values used shall be those associated with the base flood. Wind loading values used shall be those required by applicable state or local building codes. Such enclosed space shall be usable solely for parking of vehicles, building access or storage. (f) There shall be no alteration of sand dunes or mangrove stands which would increase potential flood damage. (g) All manufactured homes to be placect or substantially improved within V- Zones shall comply with the same standards as set forth for conventional housing in V- Zones. (h) All recreational vehicles placed in V-Zones shall be (i) on site for fewer than 180 consecutive days, (ii) be fully licensed and ready for highway use, or (iii) meet the same standards as for conventional housing in V-Zones.
