Minor Alteration No. WA2026120 – Sacramento River Erosion Repair Project

To repair an approximately 3,200-square-foot waterside slope slip encompassing approximately 63 linear feet of bank along the Sacramento River, consistent with the Operation and Maintenance Manual, “West Levee of Sacramento River from Sacramento Weir to River Mile 51.2 and South Levee of Sacramento Bypass and East Levee of Yolo Bypass from Sacramento Bypass to South Boundary of Reclamation District No. 900.” The proposed work includes removal of approximately five cubic yards of sloughed material and reconstruction of the levee slope to its existing profile, elevation, and cross-section. Approximately 80 cubic yards of rock slope protection and filter gravel will be placed to stabilize the repaired slope, including a keyed rock toe at the bottom of the slope. The site will be cleared and grubbed as necessary, including removal of trees and vegetation within the construction limits. Construction will include an initial stabilization phase involving placement of rock to establish a working platform, followed by final stabilization of the bank. Willow bundles will be installed at the top of the working platform as part of the final stabilization.
