The report in today's Washington Post suggesting that man-made interventions in the 100-year floodplain -- development, farming, wetlands disruption -- was to blame for the catastrophic flooding losses in Iowa got a few of us thinking here at the Lincoln Institute whether this matter had been examined before. Sure enough, publications director Ann Leroyer recalled a 1996 policy focus report entitled On Borrowed Land: Public Policies for Floodplains. The impetus was a review of what happened in the Great Flood of 1993 along the Upper Mississippi and its tributaries. "Although governments may not yet be able to manage the weather, they can improve the management of floodplains to reduce damages caused by flooding," the report says. "Rather than spend national tax dollars on flood control structures and post-diaster aid, the federal government should provide continuously updated information about changing flood risks and land uses across whole watersheds." If it's not one thing after another, it's the same thing over and over again.
