SACRAMENTO, Calif. – The U.S. Army Corps of Engineers Sacramento District will resume construction on the Marysville Ring Levee June 11 after pausing last November for the state of California’s mandated flood season.
Upgrades on the remaining 2,600 linear feet of levee will begin this week between Jack Slough Road and Marysville High School and will continue until scheduled completion in November.
“Completing this section is just the first step,” said project manager Mark Ellis. “But it marks significant progress in reducing the flood risk for Marysville.”
After completing more than 2,000 linear feet of seepage cutoff wall in 2011, preliminary test samples showed irregular results, creating questions about its ability to meet required specifications. Additional testing will be performed on the previously constructed wall while construction resumes.
“Last year’s segment was a difficult stretch to work on, so we need to make sure it will function as intended,” Ellis said.
The Corps is working in partnership with California’s Central Valley Flood Protection Board and the Marysville Levee District to complete nearly 4,600 linear feet of seepage cutoff walls, buried vertically in the levee’s center, to reduce the flood risk associated with the ring levee’s fragile northeast reach.
The Corps awarded a $10.8 million contract to Raito Inc. of San Leandro in August 2010, using American Recovery and Reinvestment Act funding, to complete the first of four phases on the Marysville Ring Levee Project.
Nearly $100 million in upgrades are scheduled to be constructed on the 7.6-mile levee that surrounds the city of Marysville by 2015.
The U.S. Army Corps of Engineers Sacramento District provides planning, engineering, project management, environmental restoration and construction services to military and civilian customers in parts of eight western states, including California, Nevada, Utah, Arizona, Colorado, Idaho, Oregon and Wyoming.
