To require the Corps of Engineers to update Upper Mississippi River levee and floodwall design standards, and for other purposes.

HR 5722 requires the U.S. Army Corps of Engineers to update flood protection design standards for Upper Mississippi River levees and floodwalls every 20 years using the latest flood risk data, safety factors, and FEMA guidelines. It mandates public input during each update stage, including for base elevation and hydrological assumptions. The bill allows local sponsors (like cities or counties managing levees) to maintain existing flood protection levels without changing risk transfer to the federal government, and specifies that repairs must align with updated standards. This applies to federally authorized projects between Hamburg, Illinois, and Guttenberg, Iowa, covering rural, urban, and industrial areas protected to specific flood risk levels (2%, 1%, or 0.2% probability).
