Sacramento River Erosion Contract 1

Sacramento River Erosion Contract 1 is 1,150 feet of erosion protection measures located above and below the average low flow water surface elevation. These measures include but are not limited to a 5-foot-thick lens of launchable Grade C quarry stone below the water surface, a 2.5-foot-thick lens of soil-rock mix and brush layering above the water surface to protect the bank from wave wash, and transitions to existing grade at the upstream and downstream ends of the site for both soil-rock mix and quarry stone measures. Additionally, planting benches will vary in width and allow for subsequent planting of native riparian species. Benches can either be submerged or placed above the water surface depending on the target riparian species, and desired habitat. Lastly, a series of In-Stream Woody Material will be placed below the planting bench to create in-stream cover for fisheries throughout the seasons and provide some degree of flow deflection along the bank.
