(A) This chapter's protection standard is the base flood.
(B) The best available base flood data are listed below.
(C) Whenever a party disagrees with the best available data, the party may finance the detailed engineering study needed to replace the existing data with better data and submit it to the Federal Emergency Management Agency for approval.
(1) The base flood elevation for the floodplains of the village in the flood insurance study of the village prepared by the Federal Emergency Management Agency and dated November, 1979.
(2) The base flood elevation for each floodplain delineated as an "AH Zone" or "AO Zone" shall be that elevation (or depth) delineated on the flood insurance rate map of the village.
(3) The base flood elevation for each of the remaining floodplains delineated as an "A Zone" on the flood insurance rate map of the village shall be according to the best data available from federal, state or other sources. Should no other data exist, an engineering study must be financed to determine base flood elevations.
(4) The base flood elevation for the floodplains of those parts of unincorporated Madison County that are within the extraterritorial jurisdiction of the village, or that may be annexed into the village, shall be as delineated on the 100-year flood profiles of the flood insurance study of Madison County prepared by the Federal Emergency Management Agency and dated October 15, 1981.
