The U.S. Army Corps of Engineers awarded a contract last week to conduct temporary emergency levee repairs on an eroded section of the Heise-Roberts Levee System, located on the Snake River near Lorenzo, Idaho, about 3.7 miles downstream from the U.S. Route 20 bridge.
High-flow conditions in the Snake River are eroding a segment of the Heise-Roberts Levee System, about 3.7 miles downstream from the U.S. Route 20 bridge.
Immediate emergency repairs are necessary to prevent further erosion which poses a threat to the structural integrity of the levee and about 65 homes located within the leveed area, said USACE.
A team of trained flood-fight specialists from the U.S. Army Corps of Engineers, Walla Walla District, arrived on site on May 16 in response to a request from Jefferson County emergency managers for help with emergency levee repairs. Since arrival, USACE team has assessed the levee damage, determined appropriate emergency protective measures, and coordinated for construction-contract work to repair the levee.
The emergency-repair contract was awarded to Sand Point Generating, LLC, an Alaska Native Corporation in Boise, Idaho. The contractor’s crews and equipment are in the process of mobilizing to the site to begin work.
