Within coastal high hazard areas established in section 15A-7, the following standards shall apply:
(a)
All new construction, substantial improvement and other proposed new development shall
be elevated on adequately anchored pilings or columns and securely anchored to such
pilings or columns so that the lowest horizontal portion of the structural members
of the lowest floor (excluding the pilings or columns) is elevated to or above the
base flood level. The pile or column foundation and structure attached thereto is
anchored to resist flotation, collapse and lateral movement due to the effects of
wind and water loads acting simultaneously on all building components. 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 standards.
(b)
All new construction, shall be located landward of the reach of mean high tide.
(c)
All new construction, substantial improvement and other proposed new development shall
have the space below the lowest floor free of obstructions or constructed with breakaway
walls as defined in section 15A-5 of this chapter. Such enclosed space shall not be used for human habitation and will
be useable solely for parking of vehicles or building-access.
(d)
Fill shall not be used for structural support of buildings.
(e)
Man-made alteration of sand dunes which would increase potential flood damage is prohibited.
(f)
The floodplain administrator shall obtain and maintain the following records:
(1)
Certification by a registered engineer or architect that a proposed structure complies
with subsection (a) of this section.
(2)
The elevation (in relation to mean sea level) of the bottom of the lowest structural
member of the lowest floor (excluding pilings or columns) of all new and substantially
improved structures, and whether such structures contain a basement.
