Document Description
Caltrans is proposing a geotechnical investigate drilling operation in and adjacent to the Smith River at State Route 101 in order to obtain subsurface information that would inform design for replacement of the Dr. Fine Bridge. Drilling would be conducted at three (3) locations in the vicinity of the future bridge abutments and one (1) location within a jurisdictional wetland. The proposed soil borings would be approximately 4.5-inches in diameter and would be drilled to a maximum depth of 180 feet. A 5.5-inch diameter steel casing may be used at the top of the boring hole to secure drilling fluid circulation. The drilling fluids shall be contained and recirculated through a closed system-drilling fluids and products shall be fully recovered in a mud tank before being transferred to 55-gallon steel drums for disposal. The boreholes would be backfilled with cement slurry or a mixture of cement and bentonite slurry.
