The areas considered to be floodplain may be revised or modified
by the Board of Commissioners where studies or information provided
by a qualified agency or person documents the need or possibility
for such revisions. However, prior to any such change, approval must
be obtained from FEMA. Additionally, as soon as practicable, but not
later than six months after the date such information becomes available,
a community shall notify FEMA of the changes by submitting technical
or scientific data. No modification or revision of any floodplain
area identified in the FIS prepared by FEMA shall be made without
prior approval from FEMA.
Should a dispute arise concerning the identification of any
floodplain area, the final determination shall be made by the Board
of Commissioners, with the prior approval of FEMA. The burden of proof
shall be on the appellant.
