Floodplain creep and beyond: An assessment of next-generation floodplain problems

Leora S. Waldner, PhD

Abstract


Since the 1970s, local jurisdictions have made great strides in protecting their floodplains through land use ordinances. Jurisdictions that joined the National Flood Insurance Program have prohibited structures in the regulatory floodway, and several jurisdictions have gone a step further, prohibiting structures in the 100-year floodplain. What next? If local governments are successfully keeping structures away from floodplains, have they adequately addressed floodplain issues—or do other problems remain unaddressed? This research examines Atlanta-region counties, and uncovers four potential next-generation problems, including the following: (1) floodplain creep (expansion of the floodplain) resulting from increased impervious surfaces and development; (2) the unrestricted development of homes in the 100-year floodplain of small dams; (3) cumulative riparian effects of cut and fill practices; and (4) lack of information for prospective homeowners of floodplain-burdened property.
