This subchapter'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 the South Branch Kishwaukee River and the Bull Run, Kingsbury, and Owens Creeks shall be as delineated on the 100-year flood profiles in the countywide Flood Insurance Study of DeKalb County prepared by the Federal Emergency Management Agency and dated January 2, 2009.
(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 DeKalb 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 DeKalb 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) The base flood elevation for the floodplains of those parts of unincorporated DeKalb County that are within the extraterritorial jurisdiction of the Village of Kirkland, or that may be annexed into the Village of Kirkland, shall be as delineated on the 100-year flood profiles in the Flood Insurance Study of DeKalb County prepared by the Federal Emergency Management Agency and dated January 2, 2009.
