This chapter’s protection standard is the regulatory flood. The best available regulatory flood data is listed below. Whenever a party disagrees with the best available data, the party submitting the detailed engineering study needs to replace existing data with better data and submit it to the Indiana Department of Natural Resources for review and approval.
(A) The regulatory flood elevation, floodway, and fringe limits for the studied SFHAs within the jurisdiction of the City of Frankfort shall be as delineated on the 1% annual chance flood profiles in the Flood Insurance Study of Clinton County and Incorporated Areas dated December 2, 2011 and the corresponding Flood Insurance Rate Map prepared by the Federal Emergency Management Agency and dated December 2, 2011.
(B) The regulatory flood elevation, floodway, and fringe limits for each of the SFHAs within the jurisdiction of the City of Frankfort, delineated as an “A Zone” on the Clinton County and Incorporated Areas Flood Insurance Rate Map prepared by the Federal Emergency Management Agency and dated December 2, 2011, shall be according to the best data available as provided by the Indiana Department of Natural Resources; provided the upstream drainage area from the subject site is greater than one square mile.
