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 all studied rivers, creeks and streams shall be as delineated on the 100-year flood profiles in the countywide Flood Insurance Study of Franklin County prepared by the Federal Emergency Management Agency.
(b) The base flood elevation for each of the remaining floodplains delineated as a “A Zone” on the countywide Flood Insurance Rate Map of Franklin County shall be according to the best data available from Federal, State or local sources. Should no other data exist, an engineering study must be financed by the applicant to determine base flood elevations.
(c) The base flood elevation for the floodplains of those parts of unincorporated Franklin County that are within the extraterritorial jurisdiction of the City of Christopher, or that may be annexed into the City of Christopher shall be as delineated on the 100-year flood profiles in the Flood Insurance Study of Franklin County prepared by the Federal Emergency Management Agency in current use at the time.
