(A) Located within the special flood hazard areas established in § 153.07 of this chapter are areas designated as shallow flooding areas. These areas have special flood hazards associated with base flood depths of one to three feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate.
(1) All new construction and substantial improvements of residential and non-residential buildings shall have the lowest floor, including basement, elevated to at least one foot above as many feet as the depth number specified on the FIRMs, in feet, above the highest adjacent grade. If no flood depth number is specified on the FIRM, the lowest floor, including basement, shall be elevated to at least three feet above the highest adjacent grade. Openings sufficient to facilitate automatic equalization of hydrostatic flood forces on exterior walls shall be provided in accordance with standards of § 153.41 of this chapter.
(2) All new construction and substantial improvements of non-residential buildings may be floodproofed in lieu of elevation. The structure together with attendant utility and sanitary facilities must be floodproofed and designed water-tight to be completely floodproofed to at least one foot above the flood depth number specified on the FIRM, with walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy. If no depth number is specified on the FIRM, the structure shall be floodproofed to at least three feet above the highest adjacent grade. A state registered professional engineer or architect shall certify that the design and methods of construction are in accordance with accepted standards of practice for meeting the provisions of this chapter and shall provide such certification to the Administrator as set forth above and as required in accordance with § 153.41 of this chapter.
(3) Adequate drainage paths shall be provided around slopes to guide flood waters around and away from proposed structures.

(A) Located within the areas of special flood hazard established in § 153.07 of this chapter are areas of the 100-year floodplain protected by a flood protection system, but where base flood elevations have not been determined.
(Ord. 703, passed 5-24-2010)
(A) Located within the city are unmapped streams where areas of special flood hazard are neither indicated nor identified.
(B) Adjacent to such streams, the following provisions shall apply.
(1) No encroachments including fill material or other development including structures shall be located within an area of at least equal to twice the width of the stream, measured from the top of each stream bank, unless certification by a state registered professional engineer is provided demonstrating that the cumulative effect of the proposed development, when combined with all other existing and anticipated development, will not increase the water surface elevation of the base flood more than one foot at any point within the locality.

Violation of the provisions of this chapter or failure to comply with any of its requirements, including violation of conditions and safeguards established in connection with grants of variance shall constitute a misdemeanor punishable as other misdemeanors as provided by law.
