8-3-3: DISTRICT BOUNDARIES:
   A.   Adoption Of Maps; Attached Materials: The location and boundaries of the zoning districts are set forth on the Official Zoning Map which, together with all materials attached thereto, are hereby adopted by reference and declared to be part of this Title. The attached material includes the Type 19 Flood Insurance Study for Clay County prepared by McCombs-Knutson Associates, Inc., for the Federal Emergency Management Agency (FEMA) dated April 16, 1984, as amended, and the Flood Boundary and Floodway Maps, and Flood Insurance Rate Maps (FIRM) therein.
   B.   Boundary Lines: Unless otherwise specified, zoning district boundaries shall follow the center lines of streets, highways, railroad rights of way or waterways; section lines, subdivision lines, lot lines, city limits, or such lines extended.
   C.   Shoreline Boundaries: Boundaries indicated as following shorelines of bodies of water shall be construed to follow such shorelands, and in the event of change in the shoreline, shall be construed as moving with the actual shoreline.
   D.   Distances not specifically indicated on the Official Zoning Map shall be determined by the scale on the Map.
   E.   Division Of Parcel Under Single Ownership: Where a district boundary line divides a parcel which is in a single ownership at the time of passage hereof, the Board of Adjustment may permit the extension of the regulations for either portion of the parcel not to exceed fifty feet (50') beyond the district line into the remaining portion of the parcel.
   F.   Flood Plain Boundaries:
      1.   Location Of Boundary Lines: The location of boundary lines shall be determined by the Federal Emergency Management Agency (FEMA) and provided on Flood Insurance Rate Maps (FIRM) and/or Flood Boundary and Floodway Maps developed for the County. When necessary this subsection shall be amended by addition of the proper flood plain district boundaries.
      2.   Removal Of Flood Plain Designation: The flood plain designation on the FIRM or Flood Boundary and Floodway Map shall not be removed from flood plain areas unless it can be shown that the designation is in error or that the area has been filled to or above the elevation of the regional flood and is contiguous to lands outside the flood plain. Special exceptions to this rule may be permitted by the Commissioner of Natural Resources if he determines that, through other measures, lands are adequately protected for the intended use.
      3.   Determination Of Boundaries; Interpretation: Boundaries of the flood plain districts shall be determined by scaling distances on the FIRM or Flood Boundary and Floodway Maps. Where interpretation is needed as to the exact location of the boundaries of the district as shown on the FIRM or Flood Boundary and Floodway Maps, as for example where there appears to be a conflict between a mapped boundary and actual field conditions and there is a formal appeal of the decision of the Zoning Administrator, the Board of Adjustment shall make the necessary interpretation. All decisions will be based on elevations of the regional (100-year) flood profile and other available technical data. Persons contesting the location of the district boundaries shall be given reasonable opportunity to present their case to the Board of Adjustment and submit technical evidence.
      4.   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 100-year flood elevation. FEMAs 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. (Amd. Ord., 5-25-1993)
