The U.S. Army Corps of Engineers, Omaha District, and the City of Hamburg, Iowa, signed the Section 1176 project agreement Tuesday that will allow for raising the Hamburg Ditch 6 levee eight feet, significantly increasing the flood risk management benefits the levee provides to the city. This significant achievement comes after the Omaha District, city of Hamburg, and other stakeholders have worked diligently with Headquarters USACE and Northwestern Division to implement the Section 1176 Authority from the 2020 Water Resources Development Act. This is the first project across the nation to utilize the Section 1176 authority to raise the height of a federal levee system. ā€œIā€™m excited to join Mayor Cathy Crain and the city of Hamburg on this important project agreement to raise flood protection around the city of Hamburg,ā€ said Col. Mark Himes, commander, USACE-Omaha. ā€œI look forward to working with the city in the upcoming construction this spring. The Hamburg Ditch 6 levee was overtopped and sustained severe damage during the 2019 floods, leading to significant flooding within the city of Hamburg. Under the PL 84-99 program, the U.S. Army Corps of Engineers can restore levees active in the program to their pre-flood congressionally authorized elevation Section 1176 allows a levee sponsor, at their cost, an avenue to raise the elevation of a levee above its current congressionally authorized elevation after developing engineering drawings and completing studies demonstrating that the modified levee will not produce adverse impacts as a result of the raise. In total the city of Hamburg, with support from other stakeholders, will contribute $7-8 million to raise the Ditch 6 levee to its new elevation and provide additional flood risk management benefits to the city. Following the historical signing of this agreement, the construction contract for this project will be advertised later this month, and the project construction will start shortly thereafter.

Although significant strides have been made in repairing the more than 350 miles of levees across the Lower Missouri River Basin that were damaged following the historic floods of 2019, a heightened level of flood risk remains for the communities and landowners behind these damaged levee systems as repair efforts remain ongoing. This risk is higher than it was prior to the flood event because the levees are comprised of a series of components that all function together to create a complete levee system, and until all of these components, (such as seepage berms and relief wells) are repaired, the system does not fully provide the same level of flood risk reduction as it did in its pre-flood condition.

The Omaha District remains focused on ensuring the safety of citizens and remain positioned to provide flood fight assistance to state, local and tribal government agencies, as appropriate. We will also continue working with our other federal partners to communicate the conditions on the river systems as we look towards the 2021 run-off season. When severe weather and/or heavy precipitation is forecasted, the public is encouraged to keep in contact with their local emergency managers for the latest conditions in their area.
