Document Type
NOE - Notice of Exemption
Document Description
The project consists of drilling a 4-inch diameter, 120 feet deep vertical hole from the crest of San Vicente dam in order to install tilt measuring devices to monitor movement of the dam. After the hole is drilled, a fiberglass casing pipe will be installed to house and position the measuring devices. Grout will be placed around the casing pipe to lock it in place. A second 120 feet deep boring will be drilled nearby for future down-hole surveys of the dam using camera equipment. Both boring locations will be covered by a steel plate bolted to the crest slab. Conduit will be installed from the instrument bore hole, along the upstream parapet wall to the crest control building. Instrumentation wires will be connected to an existing process control cabinet for data monitoring and recording.
