Areas designated as floodways or flood fringe areas are located within the Special Flood Hazard Areas established in section 11-1-3-2. The floodways and flood fringe areas are extremely hazardous areas due to the velocity of floodwaters that have erosion potential and carry debris and potential projectiles. The following provisions, in addition to standards outlined in sections 11-1-5-1 and 11-1-5-2, shall apply to all development within such areas:
   A.   No encroachments, including fill, new construction, substantial improvements, and other developments shall be permitted unless:
      1.   It is demonstrated that the proposed encroachment would not result in any increase in the flood levels during the occurrence of the base flood, based on hydrologic and hydraulic analyses performed in accordance with standard engineering practice and presented to the Floodplain Administrator prior to issuance of floodplain development permit; or
      2.   A Conditional Letter of Map Revision (CLOMR) has been approved by FEMA. A Letter of Map Revision (LOMR) must also be obtained within six (6) months of completion of the proposed encroachment.
   B.   If subsection A is satisfied, all development shall comply with all applicable flood hazard reduction provisions of this chapter.
   C.   Manufactured homes may be permitted provided the following provisions are met:
      1.   The anchoring and the elevation standards of subsection 11-1-5-2C; and
      2.   The encroachment standards of subsection A. (Ord. 249, 8-17-2016)
