§ 18.28.110. Shallow flooding (AO Zones).

A.

Shallow flooding areas as delineated as AH and AO Zone floodplains on the Flood Insurance Rate Maps. The provisions of Chapter 18.24 and Section 18.28.100 of these regulations shall apply to any AH and AO Zone floodplains. The depth of the one-hundred-year flood is indicated as the depth of the Flood Insurance Rate Maps. The one-hundred-year flood depth shall be referenced to the highest adjacent grade or stream flow line in determining which fill or floodproofing heights to use in applying the provisions of Section 18.28.100C. and D. of these regulations. In the absence of depth or elevation information, a minimum two-foot flood depth shall be used.

B.

Floodplain Boundary Interpretation. The floodplain administrator shall make interpretations where needed as to the exact location of an AH and AO Zone floodplain boundary when there is a conflict between a mapped boundary and actual field conditions.
