Floodplain
- Anchoring to resist flotation
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.
- Breakaway wall design safe loading20 psf
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 shall be elevated on pilings or columns so that the bottom of the lowest horizontal structural member is elevated to or above the base flood level plus 18 inches if parallel to wave approach, or at least two feet above BFE if perpendicular.
- Enclosed space use
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.
- Engineer certification required
A registered professional engineer or architect shall develop or review the structural design and certify that the design meets accepted standards.
- 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.
- Landward of mean high tide
All new construction shall be located landward of the reach of mean high tide.
- Sand dune alteration 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.
- Space below lowest floor
The space below the lowest floor shall be either free of obstruction or constructed with non-supporting breakaway walls, open wood-lattice work, or insect screening intended to collapse under wind and water loads.
From the ordinance
All new construction and substantial improvements in Zones V and VE, including manufactured homes, shall be elevated on pilings or columns so that the bottom of the lowest horizontal structural member of the lowest floor 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 two feet above the base flood level if perpendicular.
