Weston Solutions Wins L575a Deal

The U.S. Army Corps of Engineers, Omaha District, awarded a $2.7 million 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.

USACE 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, said USACE.

“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, said USACE.
