§ 58-513. Specific standards for lots recorded on or after January 10, 2000.

In all special flood hazard areas where base flood elevation (BFE) data has been provided, as set forth in section 58-452, or section 58-514, the following provisions, in addition to the provisions of section 58-511, are required:

(1)

Residential construction. New construction and substantial improvement of any residential structure (including manufactured homes) shall have the reference level, including basement, elevated no lower than the regulatory flood protection elevation and shall be located outside the limits of the SFHA, as defined in section 58-431 of this article.

(2)

Nonresidential construction. New construction and substantial improvement of any commercial, industrial, or other nonresidential structure shall have the reference level, including basement, elevated no lower than the regulatory flood protection elevation and shall be located outside the limits of the SFHA, as defined in section 58-431 of this article.

(3)

Manufactured homes. New and replacement manufactured homes shall be elevated so that the reference level of the manufactured home is no lower than the regulatory flood protection elevation and shall be located outside the limits of the SFHA, as defined in section 58-431 of this article.

(4)

Recreational vehicles. Recreational vehicles shall either:

a.

Be on-site for fewer than 180 consecutive days and be fully licensed and ready for highway use (a recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities, and has no permanently attached additions); or

b.

Meet all the requirements for new construction.

(5)

Temporary nonresidential structures. Prior to the issuance of a floodplain development permit for a temporary structure, the applicant must submit to the floodplain administrator a plan for the removal of such structure(s) in the event of a hurricane, flash flood or other type of flood warning notification. The following information shall be submitted in writing to the floodplain administrator for review and written approval:

a.

A specified time period for which the temporary use will be permitted. Time specified may not exceed three months, renewable up to one year;

b.

The name, address, and phone number of the individual responsible for the removal of the temporary structure;

c.

The time frame prior to the event at which a structure will be removed (i.e., minimum of 72 hours before landfall of a hurricane or immediately upon flood warning notification);

d.

A copy of the contract or other suitable instrument with the entity responsible for physical removal of the structure; and

e.

Designation, accompanied by documentation, of a location outside the special flood hazard area, to which the temporary structure will be moved.

(6)

Accessory structures. When accessory structures (sheds, detached garages, etc.) are to be placed within a special flood hazard area, the following criteria shall be met:

a.

Accessory structures shall not be used for human habitation (including working, sleeping, living, cooking or restroom areas);

b.

Accessory structures shall not be temperature-controlled;

c.

Accessory structures shall be designed to have low flood damage potential;

d.

Accessory structures shall be constructed and placed on the building site so as to offer the minimum resistance to the flow of floodwaters;

e.

Accessory structures shall be firmly anchored in accordance with the provisions of subsection 58-511(1); "Anchoring of any accessory buildings may be done by bolting the building to a concrete slab or by over-the-top ties. When bolting to a concrete slab, one-half inch bolts six feet on center with a minimum of two per side, shall be required. If over-the-top ties are used, a minimum of two ties with a force adequate to secure the building is required."

f.

All service facilities such as electrical shall be installed in accordance with the provisions of subsection 58-511(4); and

g.

Flood openings to facilitate automatic equalization of hydrostatic flood forces shall be provided below regulatory flood protection elevation in conformance with the provisions of subsection 58-512(4)c.

An accessory structure with a footprint less than 150 square feet that satisfies the criteria outlined above does not require an elevation or floodproofing certificate. Elevation or floodproofing certifications are required for all other accessory structures in accordance with subsection 58-482(c).

(7)

Recordation of lots within SFHA. Prior to recordation of lots within the SFHA, as defined in section 58-431 of this article, the following provisions shall be met:

a.

Lots wholly located within the SFHA: No proposed residential building lot that is wholly located within the SFHA shall be approved.

b.

Lots partially located within the SFHA:

1.

No proposed residential building lot that is partially located within the SFHA shall be approved unless there is established on the lot plan a contour line representing the regulatory flood protection elevation, as defined in section 58-431 of this article. All buildings or structures designed or intended for use for residential purposes shall be located on such a lot so that the lowest floor, as defined in section 58-431 of this article, shall not be below the regulatory flood protection elevation.

2.

Where only a portion of a proposed lot is located within the SFHA, such lot may be approved only if there will be available for building a usable lot area of not less than 5,000 square feet. The usable lot area shall be determined by deducting from the total lot area, the area of all yard setbacks required by the applicable zoning regulations and any remaining area of the lot lying within the area of the SFHA as shown on the flood insurance rate map (FIRM).
