Nez Perce-Clearwater NFs - Newsome Creek Reach 2 Stream Habitat Restoration Design
Added: Mar 16, 2016 2:09 pm This project is being done in collaboration with the Nez Perce Tribe Watershed program. The goal of this partnership is to use restoration techniques to improve waterways. This contract requires data collection and analysis; preparation of design drawings, specifications, cost estimates and supporting documentation; and related work in compliance with its terms, specifications and provisions. This includes the furnishing of all labor, equipment, supervision, transportation, operating supplies and incidentals (except those designated as Government-furnished).The overall objective is to re-design the previously delineated Stream Reach 2 of Upper Newsome Creek to accommodate for the valley-wide restored floodplain and increased budget. New work elements for the Stream Reach 2 design shall be prioritized as follows: 1. New Channel and/or new channel meander construction. Woody debris structures and grade control structures associated with new channel meanders will also be added to the design. 2. New habitat improvement structures (design similar in nature to what was implemented in stream Reaches 5, 4, and 3).The design should achieve the following goals while balancing objectives, costs, and benefits.1) Improve channel morphology & stream function utilizing as much of the restored valley bottom and floodplain as feasible within Stream Reach 2.2) Increase fish habitat within Stream Reach 2 primarily tough the use of stream habitat features (pools, riffles, glides, ect.) and large woody debris. 3) Incorporate currently procured planting stock into the design of the new channel (bank stability and vegetative shading).4) Incorporate topsoil stockpiles into the overall design plan of Stream Reach 2.Background: Full restoration of Stream Reaches 5, 4, and 3 was implemented in 2011 - 2014. These completed reaches and floodplain restoration work are to be used as reference for the supplemental design for Stream Reach 2. The large woody debris "system" used on previous reaches should be referenced and carried tough Reach 2.In 2014 and 2015, dredge piles were removed from the Reach 2 floodplain to re-establish the floodplain elevation. The dredge material was placed in repositories at the toe of the hillslopes. In addition, topsoil was salvaged and placed in stockpiles. However, the Newsome Creek tough Reach 2 is still in its impacted, straightened channel and lacks structure for fish habitat. Location: The project is approximately 38 mi east of Grangeville, Idaho. At the junction of Highway 14 and the Newsome Cr Road (FR 1858), travel north for approximately 7.0 miles to the gate on the access route developed in 2011. The project BOP is approximately 1.8 miles on an unimproved access route beyond this gate. Access route grades range from 0% - 20%. Maximum grade of 20% is maintained for 0.25 miles descending off ridge to valley bottom. The project is located in T30N, R7E Section 19 and can be reached by automobile (Highway 14 and FR 1858) and high clearance vehicles or 4WD ATV (access route). Access on the 1.8 mile unimproved route is limited to foot travel prior to contract award and until snow free. Project area is typically snow covered from November-June.Timing: The solicitation will be issued in April 2016 with contract award anticipated to occur on or around May 15, 2016. Deadline for final designs documents: October 31, 2016. AG-0343-S-16-0030 Department of Agriculture Forest Service R1-Northern Region
