• Anchoring to resist flotation, collapse, and lateral movement

  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.

• Breakaway walls design load 10-20 psf20 psf

  For the purpose of this section, a breakaway wall shall have a design safe loading resistance of not less than ten and no more than 20 pounds per square foot.

• Elevation on pilings or columns

  All new construction and substantial improvements in Zones V and VE (V if base flood elevation is available) shall be elevated on pilings or columns so that: 1. The bottom of the lowest horizontal structural member of the lowest floor (excluding the pilings or columns) is elevated to or above the base flood level plus 18 inches if the lowest horizontal structural member is parallel to the direction of wave approach or elevated at least one foot above the base flood level if the lowest horizontal structural member is perpendicular to the direction of wave approach;

• Enclosed space below lowest floor limited to parking, access, storage300 sqftsq ftSquare feet. An acre is 43,560 sq ft; a typical suburban lot is 7,000–10,000.

  The enclosed space below the lowest floor shall be used solely for parking of vehicles, building access, or storage. Such space shall not be partitioned into multiple rooms, temperature-controlled, or used for human habitation. The enclosed space shall be less than 300 square feet.

• FillGrading (cut & fill)Reshaping land by removing earth (cut) or adding it (fill), often capped by volume. for structural support prohibitedProhibitedNot allowed in the district at all, short of rezoning or a variance.

  The use of fill for structural support of buildings is prohibited. When nonstructural fill is proposed in a coastal high hazard area, appropriate engineering analyses shall be conducted to evaluate the impacts of the fill prior to issuance of a development permit.

• All new construction located landward of mean high tide

  All new construction shall be located landward of the reach of mean high tide.

• Man-made alteration of sand dunes prohibitedProhibitedNot allowed in the district at all, short of rezoning or a variance.

  The man-made alteration of sand dunes, which would increase potential flood damage, is prohibited.

• Registered professional engineer or architect certification

  A registered professional engineer or architect shall develop or review the structural design, specifications and plans for the construction, and shall certify that the design and methods of construction to be used are in accordance with accepted standards of practice for meeting the provisions of Article III, Section 3-1516(A)6.a.
