§ 7B-13. Shallow flooding.

Located within the areas of special flood hazard established in Section 7B-2 are areas designated as shallow flooding. These areas have special flood hazards associated with base flood depths of one foot (1′) to three feet (3′) where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate; therefore, the following provisions apply:

(1)

All new construction and substantial improvements shall be provided with adequate drainage paths around structures on slopes to guide flood waters around and away from the proposed structures;

(2)

All new construction and substantial improvements of residential structures have the lowest floor, including basement, elevated above the highest adjacent grade to at least twelve inches (12′) above the depth number specified on the community(s FIRM (or at least two feet if no depth number is specified);

(3)

All new construction and substantial improvements of nonresidential structures shall:

(i)

Have the lowest floor, including basement, elevated above the highest adjacent grade to at least twelve inches (12′) above the depth number specified on the FIRM (or at least two (2) feet if no depth number is specified), or

(ii)

Together with attendant utility and sanitary facilities be completely floodproofed to at least twelve inches (12′) above the depth number specified on the FIRM (or at least two (2) feet if no depth number is specified) so that any space below the depth number specified on the FIRM (or at least two (2) feet if no depth number is specified) is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and effects of buoyancy.
