Urban Flooding: A Significant and Growing National Threat

Room 1629, Longworth

In much of the United States, urban rainfall and stormwater flooding is occurring and is a growing source of significant economic loss, social disruption, and housing inequality. A team from the Center for Disaster Resilience at the University of Maryland and the Center for Texas Beaches and Shores at Texas A&M University has studied the issue and will brief the results of their two-year study.

While hurricanes and extreme storm events have wreaked havoc on many urban areas, in many cases it was the intense rainfall that brought these urban areas to a standstill. Most of this flooding is taking place outside of FEMA-mapped 100-year floodplains. Extensive suburban development that creates higher flood flows into urban areas, aging and frequently undersized infrastructure in older sections of communities, an inability to maintain existing drainage systems, increases in intense rainfall events, inadequate risk communication, and uncoordinated watershed management all contribute to these increases in urban flooding. 

While primary responsibility for mitigation of urban flooding rests with local governments, the division of responsibilities among federal, state, regional, local, and tribal governments for urban flood and stormwater management are not clearly defined and create significant challenges. The growing number of extreme rainfall events that produce intense precipitation are resulting in—and will continue to result in—increased urban flooding unless steps are taken to mitigate their impacts.

The Center for Disaster Resilience at the University of Maryland and the Center for Texas Beaches and Shores at Texas A&M University will release it's two-year long study on November 28th and brief Hill staff that morning. We hope you can join.
