This chapter's protection standard is the base flood. The best available base flood data are listed below. Whenever a party disagrees with the best available data, the party shall finance the detailed engineering study needed to replace the existing data with better data and submit it to the FEMA and IDNR/OWR for approval prior to any development of the site.
(A) The base flood elevation for the floodplains of Hayes Branch and Scattering Forks shall be as delineated on the 100-year flood profiles in the countywide Flood Insurance Study of Douglas County prepared by the Federal Emergency Management Agency and dated May 24, 2011.
(B) The base flood elevation for each floodplain delineated as an AH Zone or AO Zone shall be that elevation (or depth) delineated on the county wide Flood Insurance Rate Map of Douglas County.
(C) The base flood elevation for each of the remaining floodplains delineated as an "A Zone" on the countywide Flood Insurance Rate Map of Douglas County shall be according to the best data available from federal, state or sources. Should no other data exist, an engineering study must be financed by the applicant to determine base flood elevations.
(D) D. The base flood elevation for the floodplains of those parts of unincorporated Douglas County that are within the extraterritorial jurisdiction of the City of Tuscola, or that may be annexed into the City of Tuscola, shall be as delineated on the 100-year flood profiles in the Flood Insurance Study of Douglas County prepared by the Federal Emergency Management Agency and dated May 24, 2011.
