This project consists of structural excavation to remove existing cross culverts, installation of replacement cross culverts, cut-off walls, and rock slope protection, as needed. Trenches will be backfilled, hot mix asphalt placed, and striping painted. If water is present at the worksite or has the potential to come into contact with curing concrete, a water diversion plan will be implemented. Erosion and sediment control BMPs will be used and installed at each worksite. No trees will be removed during
construction; however, some pruning and ground vegetation may be required to access the work sites.
