Sacramento River Erosion (SRE) C5 Pioneer Bridge Levee Improvements

Active

Contract Opportunity

AMENDMENT 0001 - replaced specifications in its entirety and updated wage determination. Project is design-bid-build construction services to construct levee improvements at Sacramento River Erosion (SRE) Site 1, located under the I-80 Pioneer Bridge in Sacramento, California (CA). The project is anticipated to reduce the risk of levee failure from an erosion related levee breach for approximately 1,000 feet along the Sacramento River. The project is anticipated to include several erosion protection measures located above and below the average low flow water surface elevation (~7 feet NAVD88 as defined) using rock bank protection to include a 3.5-foot-thick lens of launchable Graded Stone C below the water surface to protect the bank from scour and erosion as well as Graded Stone C extended above the water surface to the top of the bank under the Pioneer Bridge section. The project is anticipated to include a 3.5-foot-thick lens of soil-rock mix above the water surface to protect the bank from wave wash generated by boat wakes and wind waves, demolition and removal of the existing upper bank material under the I-80 Pioneer Bridge section to provide a suitable foundation for the Graded Stone C, and In-stream Woody Material (IWM) to be placed below the water line to create in-stream cover for fisheries throughout the seasons and provide flow deflection along the bank. Work shall be completed by barge.
