(2) If section 94-90(1) above is satisfied, all new construction and substantial <br /> improvements shall comply with all applicable flood hazard reduction provisions of <br /> division 3. <br /> (3) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood <br /> Insurance Program Regulation, a community may permit encroachments within the <br /> adopted regulatory floodway that would result in an increase in base flood <br /> elevations, provided that the community first completes all of the provisions <br /> required by Section 65.12. <br /> Sec. 94-91. -Coastal high hazard areas. <br /> Located within the areas of special flood hazard established in section 94-38 of this <br /> chapter are areas designated as coastal high hazard areas (zones V1-30, VE, and/or V). These <br /> areas have special flood hazards associated with high velocity waters from tidal surges and <br /> hurricane wave wash; therefore, in addition to meeting all provisions outlined in this chapter, the <br /> following provisions must also apply: <br /> (1) Obtain the elevation (in relation to mean sea level) of the bottom of the lowest <br /> structural member of the lowest floor (excluding pilings and columns) of all new and <br /> substantially improved structures, and whether or not such structures contain a <br /> basement. The floodplain administrator shall maintain a record of all such <br /> information. <br /> (2) All new construction shall be located landward of the reach of mean high tide. <br /> (3) All new construction and substantial improvements shall be elevated on pilings <br /> and columns so that: <br /> (i)The bottom of the lowest horizontal structural member of the lowest floor <br /> (excluding the pilings or columns) is elevated to or above the base flood <br /> level; <br /> (ii)The pile or column foundation and structure attached thereto is anchored <br /> to resist flotation, collapse and lateral movement due to the effects of wind <br /> and water loads acting simultaneously on all building components. Water <br /> loading values used shall be those associated with the base flood. Wind <br /> loading values used shall be those required by applicable state or local <br /> building standards. A registered professional engineer or architect shall <br /> develop or review the structural design, specifications and plans for the <br /> construction, and shall certify that the design and methods of construction <br /> to be used are in accordance with accepted standards of practice for <br /> meeting the provisions of(3)(i) and (ii) of this section. <br /> (4) Provide that all new construction and substantial improvements have the space <br /> below the lowest floor either free of obstruction or constructed with non-supporting <br /> breakaway walls, open wood lattice-work, or insect screening intended to collapse <br /> under wind and water loads without causing collapse, displacement, or other <br /> 17 <br />
