The following requirements apply to the floodplains delineated by approximated methods and identified as zone A on the official maps:
A. Uses Allowed Without Permits: All uses allowed in a floodway, according to the provisions of subsection 12-5-2A of this chapter shall also be allowed without a permit in zone A.
B. Uses Requiring Permit: The requirements of subsection 12-5-3B of this chapter shall also apply to zone A floodplains. Since there are no base flood elevations computed for a zone A, the following conditions also shall apply:
1. Base flood elevations shall be provided for subdivision proposals and other proposed developments which contain at least fifty (50) lots or five (5) acres (whichever is less) and those base flood elevations shall be used in applying these regulations;
2. The floodplain administrator may obtain, review, and reasonably use any base flood elevation or floodway data available from a federal, state, or other source, until such data has been provided by the federal emergency management agency to enforce these regulations;
3. Historical flood elevations may be used by the floodplain administrator in determining suitable fill or floodproofing elevations to be achieved, and used to enforce these regulations;
4. If historical flood evidence is not available, then the floodplain administrator shall determine, from a field review at the proposed development site, an appropriate fill or floodproofing elevation or both to be utilized in applying these regulations. In the absence of depth or elevation, a minimum two foot (2') flood depth shall be used; and
5. Proposed structures must be anchored to prevent flotation or collapse and must be located as far from stream channels as practicable.
C. Prohibited Uses: Those uses prohibited in the floodway fringe, in accordance with subsection 12-5-3C of this chapter, shall also be prohibited within the zone A boundaries.
D. Floodplain Boundary Interpretation: The floodplain administrator shall make interpretations where needed, as to the exact location of the zone A boundary when there appears to be a conflict between a mapped boundary and actual field conditions. (Ord. 2011-5, 10-17-2011)
