Document Description
DFD and a Contractor will perform repairs on failed portions of the soil cement liner of Clifton Court Forebay. Two sites will have an excavator remove failed soil cement to lay back the slope, then fill the void with sandy gravel filter material followed by rip-rap on top of each location. One site will have articulated concrete mats (ACM) transported by flatbed truck where equipment will place the ACMs on top of the grouted erosion and anchor them at the top. The other erosion will be repaired using non-shrink grout mixed on site by hand and packed into gaps. After repairing the liner, DFD will apply asphalt to overlay the roadway that may be damaged by the excavator or other equipment. Paving equipment will be used to finish the asphalt. The entire project is within DFD right-of-way.
