F - Longley Drill Project

The Longley Drill project will involve drilling 10,000 holes within the Longley Restoration project area.  These holes will be used for planting 1 gallon potted plants. Location  The project is located on 1.5 miles of the Grande Ronde River approximately 3 miles from Hilgard (T 3S, R 36E, S 11 & 14).Drill 10,000 holes for planting.  Holes need to be 10” to 12” in diameter and 2’ deep. Work Period:  10/03/2022 – 10/14/2022.A total of 10,000:  10”- 12” diameter by 2’ deep holes will be drilled within the Longley Restoration Project.  Hole spacing will be approximately 8’ apart.  All areas will be accessible for equipment and are located a maximum of .5 miles from existing roads.  The work period is 10/03/2022 – 10/14/2022. Approximately 25% of the holes will need to be drilled over the streambank, within/adjacent to woody debris.  In addition, if wet conditions occur, wheeled machines used for drilling will have traction issues.  Therefore, the type of equipment used to drill the holes needs to be able to accomplish the task of drilling over streambanks, within woody debris and have appropriate traction for onsite conditions. Approximately, 33% of the holes will need to be drilled on the opposite side of the Grande Ronde River and/or side channels of the Grande Ronde
