Document Description
The project is limited to geotechnical borings and site preparation required to conduct the borings. The project consists of vegetation and tree removal from the site to facilitate use of a drill rig, excavation and grading to create a temporary drilling pad, and drilling of a total two approximately 6-inch diameter bore holes to a depth of
approximately 100 feet below the ground surface. Boring will occur in two locations, with one bore hole per location. The first location is on the east side of the river in an existing gravel parking lot and will not require any vegetation removal or grading and will not cause any impact to riparian habitat. The second location is on the west side of the river and will require vegetation clearing and grading, resulting in approximately 3,912 square feet of temporary impact to riparian habitat. Upon completion of the process, the bore holes will be backfilled with a concrete slurry and capped with 12-inches of native soil. The site will then be restored with native riparian vegetation. No
permanent structures or fill will remain onsite after the completion of the project. Approximately 10 trees will be removed as part of this project. As part of the project, approximately 4,911 square feet of riparian habitat will be restored or enhanced and approximately 50 native riparian trees will be replanted.
