Document Description
The PG&E Gas Lines 400/401 Mile Point 201.93 project consists of the installation of an approximately 1740 square foot grout mattress along the bed of an unnamed irrigation ditch, and a 10 foot high flexible concrete revetment (FRC) along either bank of the ditch for 90 feet. In order to install the mattress and FCR, approximately 75 cubic yards will be cut from the banks and the ditch will be contoured. The mattress and FCR are being installed over a high pressure gas pipeline that crosses the ditch and was recently exposed. The new features will recovefr the exposed pipe, help stabilize the banks of the ditch, and prevent future exposure of the pipe.
