Document Description
The investigations will provide analytical data for soil that is anticipated to be excavated as part of the American River Watershed Common Features 2016 Project — American River Contract 3, which is being implemented by the U.S. Army Corps of Engineers (USACE). Borings will be conducted using hand-auger, hollow stem auger (HSA), and rotary wash drilling methods. A flat-bottomed boat would be used to access some of the boring locations. Soil cuttings from the island borings will be spread around the boring location and covered with straw. Soil cuttings from the other boring locations will be disposed of at an appropriate waste facility. Excavated soils from these locations will be stored in 55-gallon drums or in 20 cubic yard bins pending receipt of analytical results. The drums or bins will be watertight and stored at a location approved by USACE, Central Valley Flood Protection Board, and Sacramento Area Flood Control Agency. After completion, borings will be backfilled to ground surface with cement/bentonite grout according to Sacramento County Environmental Management Department permit requirements.
