The project consists of excavating typically 1 to 2 feet into the inboard slopes and canal bottom, and placement of filter modified crushed surfacing base course under the liner for regrading of the slope and canal bottom and improving the drainage under the liner. A textured 30-mil LLDPE geomembrane will be installed from the crest of the right embankment to the crest of the left embankment. A cushion geotextile will be placed under the geomembrane to reduce the risk of installation damage to the geomembrane. The geomembrane and cushion geotextile will be secured in anchor trenches at the crest ends of the liner and fused/welded with existing liner at the upstream and downstream ends. It will be covered with fiber-reinforced shotcrete on the inboard slopes and canal bottom. Additional details of the proposed construction are described in the Zone 18 Shotcrete Liner Repair report. The Liner Installer's Quality Control Plan specific to the geomembrane and geotextile installation is presented in Appendix G for additional detail regarding liner installation and quality control requirements.
