Upper Brushy Creek (UBC) Dam 16 Auxiliary Spillway Cutoff Wall

Project includes the excavation of a 36-inch, 15 feet deep trench that spans the length of the auxiliary spillway control section centerline (approximately 240 LF) and keys into the auxiliary spillway berms. The unreinforced concrete cutoff wall will be installed in a trenched excavation. The concrete will be of sufficient unconfined strength (4,000psi) and chemical admixtures will be required to be added to the concrete to reduce shrinkage. The top of the wall will be flush with the ground at elevation 730.3 feet. Topsoil placement on all areas affected by construction is required.
