§ 7-92. Coastal high hazard areas (VE and V1-30 zones).

Coastal high hazard areas are special flood hazard areas established in section 7-87 and designated as zones VE or V1-30. These areas have special flood hazards associated with high velocity waters from surges and, therefore, in addition to meeting all provisions in this chapter, the following provisions shall apply to all new construction, substantial improvements and all other development:

(1)

All development shall:

a.

Be located landward of the reach of mean high tide;

b.

Be located landward of the first line of stable natural vegetation, and

c.

Comply with all applicable CAMA setback requirements.

(2)

All development shall be elevated so that the bottom of the lowest supporting horizontal member (excluding pilings or columns) is located no lower than the regulatory flood protection elevation. Floodproofing may not be utilized on any structures in coastal high hazard areas to satisfy the regulatory flood protection elevation requirements.

(3)

All space below the regulatory flood protection elevation shall be open so as not to impede the flow of water.

(4)

Open wood lattice work or mesh insect screening may be permitted below the regulatory flood protection elevation for aesthetic purposes only and must be designed to wash away in the event of abnormal wave action and in accordance with subsection 7-87(4)(b). Design plans shall be submitted in accordance with subsection 7-67(a)(4)c.

(5)

All development shall be securely anchored on pilings or columns.

(6)

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 all building components.

(7)

A registered professional engineer or architect shall certify that the design, specifications and plans for construction are in compliance with the provisions contained in section 7-67 and subsections 7-92(4), (6) and (8) of this chapter.

(8)

There shall be no fill used as structural support. Non-compacted fill may be used around the perimeter of a building for landscaping/ aesthetic purposes provided the fill will wash out from storm surge, thereby rendering the building free of obstruction prior to generating excessive loading forces, ramping effects, or wave deflection. Design plans shall be submitted in accordance with subsection 7-67(a)(4)c. The floodplain administrator may approve design plans for landscaping/aesthetic fill only after the applicant has provided an analysis by an engineer, architect, and/or soil scientist which demonstrates that the following factors have been fully considered:

a.

Particle composition of fill material does not have a tendency for excessive natural compaction;

b.

Volume and distribution of fill will not cause wave deflection to adjacent properties; and,

c.

Slope of fill will not cause wave run-up or ramping.

(9)

There shall be no alteration of sand dunes which would increase potential flood damage.

(10)

No manufactured homes shall be permitted except in an existing manufactured home park or subdivision. A replacement manufactured home may be placed on a lot in an existing manufactured home park or subdivision provided the anchoring and elevation standards are in compliance with this section.

(11)

Recreational vehicles shall be permitted in coastal high hazard areas provided that they meet the recreational vehicle criteria of subsection 7-87(6)a. and the temporary structure provisions of subsection 7-87(7).
