water and with structural components having the capability of resisting
hydrostatic and hydrodynamic loads and effects of buoyancy. Further, a
registered professional engineer or architect shall certify to the Building Official
that the flood-proofing methods for the building are adequate to withstand the
flood depths, pressures, velocities, impact and uplift forces and other factors
associated with the one hundred-year flood. The Building Official shall maintain
a file of all such certifications including the specific elevation [in relation to
mean sea level] to which such structures are flood-proofed.
(d) Utilities. New and replacement utility systems including but not limited to
water, gas, sewer, electric and telephone systems [including on-site systems] to
be placed in a floodway fringe shall be located to avoid impairment, damage,
contamination or infiltration during flooding.
(e) Anchoring. No building or other structure not anchored to a permanent
foundation shall hereafter be placed or substantially improved in a floodway
fringe.
(f) Open Storage. No open storage of materials subject to floating away during a
flood shall be permitted in a floodway fringe district unless said storage is
placed on an approved fill at least 3 inches above the elevation of the nearest
outer boundary of the floodway fringe.
(g) Hazardous Substances. Storage of hazardous substances shall be permitted in
the floodway fringe only in completely enclosed structures which comply with
the provisions of this Section. Open and below ground storage of hazardous
substances is prohibited in the floodway.
Section 14.12. Coastal High Hazard Areas [V Zones].
Located within the areas of special flood hazard are areas designated as Coastal
High Hazard areas. These areas have special flood hazards associated with wave wash;
therefore, the following provisions shall apply:
(a) All buildings or structures shall be located 25 feet landward of the reach of the
mean high tide.
(b) All buildings or structures shall be elevated so that the bottom of the lowest
supporting horizontal member, excluding pilings or columns, is located 3
inches above the base flood elevation level, with all space below the lowest
supporting member open so as not to impede the flow of water. Breakaway
walls may be permitted and must be designed to wash away in the event of
abnormal wave action.
(c) All buildings or structures shall be securely anchored in pilings or columns.
(d) All pilings and columns and the attached structures shall be anchored to resist
flotation, collapse, and lateral movement due to the effect of wind and water
loads acting simultaneously on the building components. The anchoring and
support system shall be designed with wind and water loading values which
equal or exceed the 100-year mean recurrent interval [one percent annual
chance flood].
