Multipurpose Structure Rehab - Cedar Creek Watershed

Improvements and repair of the existing earthen embankment and structural spillways. Major Project work includes the raising of the dam crest by 5 to 6 feet, the filling and flattening of the downstream slope with general fill and lime-treated fill to a 3H:1V slope ratio, the replacement of the upstream stone riprap, the construction of a new principal spillway tower, conduit and impact basin, the replacement of the existing structural spillway, widening and improvements to the auxiliary spillway, construction of a new raw water pipeline, and the installation of internal drainage piping along the dam toe and structures. The work will require approximately: 56,000 cubic yards of common excavation; 105,000 cubic yards of earthfill; 57,000 cubic yards of lime treated earthfill; 194,000 square yards of topsoil, 221 feet of 60-inch principal spillway conduit, 3,110 cubic yards of concrete; 429,000 pounds of reinforcing steel; 28,000 tons of rock riprap; 2,660 cubic yards of drainfill; 1,510 square yards of block-face, MSE retaining wall; 2,600 cubic yards of gravel road base; 800 linear feet of chain-link fence; 16,000 linear feet of barbed-wire fence; and 96 acres of vegetation. Soil disturbing activities will include: constructing the access; excavating and placing earth fill on the embankment crest, downstream slope, wave berm and upstream (back) slope; placing rock riprap on the wave berm; stripping and excavating of borrow areas; disposing of waste materials; and grading, shaping, and replacing topsoil. Construction will require care-of-water and the installation and removal of a cofferdam system.
