In these areas, no placement of above grade structures, dams or other obstructions to flow are permitted without the approval of the Municipality of Groveport;
      (3)   Existing or Man-made Surface Drainage Courses: Drainage easements shall be provided over and along any important existing or man-made surface drainage courses, adequate in dimension for the purpose of protecting, maintaining, widening, deepening, enclosing or otherwise improving such drainage courses for drainage purposes:
         A.   In these areas, no alteration of terrain or placement of above grade structures, dams or other obstructions to flow are permitted without the approval of the Municipality of Groveport.

         C.   On large or lengthy drainage courses, a maintenance strip within the easement on both sides of the watercourse may be required by the Municipality Engineer. A fifteen (15) foot minimum access easement to these areas shall be dedicated to the Municipality to the nearest public right-of-way.
      (4)   Special Flood Hazard Areas: Existing streams, ditches, creeks, and/or rivers with special flood hazard areas as designated by the Municipality or as depicted on the Federal Emergency Management Agency's (FEMA) most recent published Flood Insurance Rate Map for Groveport:
         A.   A drainage easement shall be provided over, along and on both sides of all stream channels under this designation, to include the limits of the floodplain associated with the one-percent annual chance flood.
         B.   In lieu of an easement, a landowner may elect to place the one-percent annual chance floodplain limits within a dedicated reserve to be recorded with the Final Plat or by separate instrument. The stated purpose of the drainage easement and/or reserve shall be for preservation and maintenance of floodplain conveyance and storage.
         C.   Fill within limits of the floodplain associated with the one-percent annual chance flood: fill shall not diminish the volume of natural storage or conveyance capacity of the floodplain areas, without compliance with the Municipality's Flood Plain Regulation.
      (5)   Access and Maintenance of Stormwater Management Facilities: Unless otherwise approved by the Municipality Engineer, specific dedicated drainage easement rights shall be required in order to provide for necessary maintenance of all stormwater facilities:
         A.   Generally, a drainage easement of twenty (20) feet minimum width, in addition to the size of the stormwater facility when flooded at capacity, is required. The twenty (20) foot minimum distance around the perimeter of the stormwater facility must be on a maximum slope of 10:1.
         B.   A twenty (20) foot minimum access easement shall also be required from the drainage easement to the nearest public right-of-way. The access easement must be graded in such a manner to allow the ingress and egress of maintenance vehicles.
         C.   The maintenance and responsibility of the stormwater management facility will be so stated in the easement and/or plat.
   (e)   Certificate of Drainage: Certificate of Drainage compliance shall be submitted at time of final inspection. (Ord. 19-011. Passed 4-22-19.)
