§ 30-279. Development within areas of special flood hazard.

(a)

All development within areas of special flood hazard as delineated on the official flood insurance rate maps (FIRM) or as determined by the county engineer shall comply with the following requirements:

(1)

Establish, to the satisfaction of the county engineer, the elevation of the base flood (one-hundred-year flood).

(2)

Set the minimum finished floor elevation at least one (1) foot above the elevation of the base flood.

(3)

For commercial or industrial developments, floodproofing may be substituted in lieu of elevating the finished floor.

(4)

Provide compensating storage for all floodwater displaced by development below the elevation of the base one-hundred-year flood.

(b)

Compensating storage is to be accomplished between the normal high water of the special flood hazard area and the estimated one-hundred-year flood elevation.

(c)

All developments within riverine flood hazard areas shall be designed to maintain the flood-carrying capacity of the floodway such that the base flood elevations are not increased, either upstream or downstream.
