Document Description
The proposed project includes geotechnical work for the larger bridge expansion project. The Geotechnical team will drill 10 borings a maximum depth of 100-feet below the existing grade, one at each of the abutments and one at pier location. Boring will be taken both upstream and downstream of the existing bride piers and abutments. A mud rotary with either a track or balloon-tired all terrain drill will be used to drill the bores. There are accesses on both sides of the existing low water crossing which can accommodate for the drill rig to access the river bed. Each boring hole will be backfilled with lean concrete slurry grout. Less than 3 square feet will be permanently impacted from the diameter bore holes.
Class 6 consists of basic data collection, research, experimental management, and resource evaluation activities which do not result in a serious or major disturbance to an environmental resource. These may be strictly for information gathering purposes, or as part of a study leading to an action which a public agency has not yet approved, adopted, or funded.
