(A) This chapter’s protection standard is the base flood. The best available base flood data are listed below.
(B) 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:
(1) The base flood elevation for the floodplains of the Mississippi River, Apple River, Plum River, Carroll Creek, Rush Creek, Johnson Creek, Rock Creek and Straddle Creek shall be as delineated on the 100-year flood profiles in the countywide flood insurance study of Carroll County prepared by the Federal Emergency Management Agency during the re-evaluation done in 2009 and 2010; and
(2) The base flood elevation for each of the remaining floodplains delineated as a “A Zone” on the countywide flood insurance rate map of Carroll 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.
