Document Description
This project will repair levee erosion on the left bank of the Sacramento River at RM 46.7, adjacent to the town of Freeport. The site is 490 linear feet, including a 2 foot high scarp as well as two adjacent 3 foot high scarps near the crown of the levee with dimensions of 20 to 40 feet long respectively with a 20 foot wide transition between the two scarps. The repair consists of restoring the levee to its previous slope of 3:1 by replacing approximately 1,500 cubic yards of soil filled angular rock (rip rap) on the eroded site. The repair will occur above the mean summer wate level. Work will occur between August 16 and October 30 and will take approximately 10 working days to complete. The work will either be done from a barge on the river or by a dragline or long-arm backhoe and ground crews from the levee crown and road above. Native willow live pole cuttings and other native plants, such as buttonbush, will be driven/planted into the soil between the rocks along the water's edge. No work will occur and no plantings will be installed in the 88 linear feet that has been delineated as potential Delta Smelt spawning habitat. No more than 10 feet upstream and downstream of each erosion site will be disturbed.
