The Camden County Commission has adopted a flood plain management ordinance that will show waterfront property as part of the flood area in Camden County. The commissioners agree the map is flawed and places a financial burden on property owners. The only other option would be to opt out of FEMA’s flood plain maps. That would make Camden County property owners ineligible for the national food insurance program, which would effectively halt real estate transactions and development unless the buyer or developer paid with cash. County commissions across Missouri have until June 15 to accept the new maps that FEMA drafted through an engineering analysis and a study by the U.S. Geological Survey and Army Corps of Engineers.
