§ 8-3-4. Standards for shallow flooding areas.

Located within the areas of special flood hazard established in section 8-1-8, are areas designated as shallow flooding areas. These areas have flood hazards associated with base flood depths of one to three feet, where a clearly defined channel does not exist and the water path of flooding is unpredictable and indeterminate; therefore, the following provisions apply:

(1)

All new construction and substantial improvements of residential structures shall: Have the lowest floor, including basement, elevated in zone AH to or above either the base flood elevation (plus one foot of freeboard) or in zone AO the flood depth specified on the flood insurance rate map (plus one foot of freeboard), above the highest adjacent grade.

(2)

All new construction and substantial improvements of non-residential structures shall:

a.

Have the lowest floor, including basement elevated in zone AH to or above either the base flood elevation plus one foot of freeboard or in zone AO the flood depth specified on the flood insurance rate map plus one foot of freeboard, above the highest adjacent grade. In zone AO, if no flood depth is specified, the lowest floor, including basement, shall be elevated no less than three feet above the highest adjacent grade.

b.

Together with attendant utility and sanitary facilities be completely floodproofed in zone AH to the base flood elevation plus one foot of freeboard or above or, in zone AO, to or above the specified flood depth plus a minimum of one foot so that any space below that level 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. Certification is required as stated in subsection 8-3-2(2).
