Straight Slough Channel Cleanout

About the Project

This USACE project consisted of establishing a channel bottom width of 100 feet to 110 feet, depending upon channel location, while re-establishing a work-side channel side slope of 1V:2H. The excavation, totaling 1,012,000 CY, began at the downstream project limit and proceeded upstream. Ditch excavation operations were performed by Manitowoc 4600 and 4500 draglines. Work also included placing R200 riprap and filter gravel along the channel bank, excavated material placement within the right-of-way limits, clearing, snagging, stripping of topsoil, establishment of turf, and erosion control.
