The U.S. Army Corps of Engineers, Omaha District, awarded a $2,767,413 contract Wednesday to build up the elevation on previously closed breach L575a near Percival Iowa, and on breach 575b near Hamburg, Iowa expected to be closed in the next few days.

The Corps of Engineers awarded the contract to Weston Solutions, Inc. of West Chester PA. The breach closure will ensure that a minimum level of protection is provided during repairs of critical infrastructure behind the levee. The initial breach closures are scheduled for completion within 45 calendar days of the contract award.

“These repairs are the second stage of repairs at two breach locations,” said Patricia Lambert, Deputy Chief, System Restoration Team. “One of the initial breaches was closed on June 20th. The second breach is targeted to be closed by the end of this weekend. This new contract will build on those initial breach closure pads to bring the levee elevations at those breaches up another two feet to 4.5 feet.  Final designs for this levee system are in the engineering and design phase in order to eventually restore the levee to its authorized level.”

The objective of the repair work is to increase the level of flood risk management to approximately the 4% Annual Chance Exceedance (25‐yr) level for this section of the L575 Levee System until the system can be fully rehabilitated. This scope of work also includes interim repairs.

There are more than 500 miles of levees on the Missouri, Platte and Elkhorn rivers, and tributaries that have experienced significant flood damage. Due to the magnitude of damage along these levees, repair of the levee system efforts will take an extended period of time to execute. Levees must be active in the Public Law 84-99 program to be eligible for federal funding for repairs.

Omaha District’s focus remains on ensuring the safety of citizens and communicating the conditions on the river systems to all of its partners and stakeholders. The Corps continues to provide flood fight assistance to state, local and tribal government agencies.
