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 state’s 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 town shall be as delineated on the 1% annual chance flood profiles in the Flood Insurance Study of Boone County and Incorporated Areas dated 1-18-2012 and the corresponding Flood Insurance Rate Map prepared by the Federal Emergency Management Agency and dated 1-18-2012.
(B) The regulatory flood elevation, floodway and fringe limits for each of the SFHAs within the jurisdiction of the town, delineated as an “A Zone” on the Boone County and incorporated Areas Flood Insurance Rate Map prepared by the Federal Emergency Management Agency and dated 1-18-2012, shall be according to the best data available as provided by the state’s Department of Natural Resources; provided, the upstream drainage area from the subject site is greater than one square mile.
