JHL Veggie-Rap

This project is to remove vegetation and rehabilitate the revetment of the Jackson Project Levees, as well as perform short notice repairs of levee sites damaged by spring river flows. The project is in Teton County, Wyoming, near the town of Jackson. The project consists of 28 levees (33 miles total), 48 levee access roads, and 5 riprap stockpile sites. The contractor selected to perform this work will be required to perform work to include: Remove and dispose of vegetation located on project levees, sized from brush to trees more than 20” in diameter, in a legal manner. Load and transport government furnished riprap and/or fill material to worksites from Project Stockpiles. Rock weighs up to 3000 pounds. Temporarily remove existing revetment to enable re-grading of slopes of levee to a specified profile. Excavate for a toe trench to replace/reconstruct the levee toe. This work will occur in-water for approximately 50% of the levee length, on average. Place levee fill material in lifts. Compact levee fill to specification standards with compaction equipment. Mix new riprap with old material, placing rock individually on levee profile and toe to ensure rock is properly keyed. Some of the work will be performed in the water by excavators. In these locations where the river is immediately adjacent to the levee, only the bucket of the excavator will enter the water. Waters of this region of the Snake River routinely exceed 10 feet/second in velocity.
