(a) Estimate the peak discharge of the regional flood; (b) Calculate the water surface profile of the regional flood based upon a hydraulic analysis of the stream channel and overbank areas; and - (c) Compute the floodway necessary to conveyor store the regional flood - without increasing flood stages more than 1/2 foot. A lesser stage increase than 1/2 foot shall be required if, as a resolution of the additional stage increase, increased flood dam:tges would result. An equal degree of encroachment on both sides. of the stream within the reach shall be assumed in computing floodway boundaries. (3) The Zoning Administrator shall present the technical evaluation and findings of the designated engineer or expert to the City Council. The City Council must formally accept the technical evaluation and the recommended Floodway or Flood Fringe District boundary or deny the permit application. The City Council; prior to official action, may submit the application and all supporting data and analyses to the Federal Emergency Management Agency, the Department of Natural Resources or the Planning and Zoning Commission for review and comment. Once the Floodway and Flood Fringe Boundaries have been determined, the City Council shall refer the matter back to the Zoning Administrator who shall process the permit application consistent with the applicable provisions of this. chapter.

No land shall be subdivided which is unsuitable for the reason of flooding, inadequate drainage, water supply or sewage treatment facilities. Alllots within the floodplain districts shall contain a building site at or above the regulatory flood protection elevation. All subdivisions shall have water and sewage treatment facilities that comply with the provisions of this chapter and have road access both to the subdivision and to the individual building sites no lower than 2 feet below the regulatory flood protection elevation. For all subdivisions in the floodplain, the floodway and flood fringe boundaries, the regulatory flood protection elevation and the required elevation of all access roads shall be clearly labeled on all required subdivision drawings and platting documents. (B) Removal of special flood hazard area designation. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 1 DO-year flood elevation. FEMA' s requirements incorporate specific fill compaction and side slope protection standards for multi-structure or multi-lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested. .- .- (C) Scope of section. This section is not intended as a substitute for a comprehensive city or county subdivision ordinance. It can, however, be used as an inte~ control until the comprel1ensive subdivision ordinance can be amended to iIJ.clude necessary floodplain mam~gement provisions. (Old. 33-A, passed 4-12-1989; Am.
