The objective of the Crooked River Valley Rehabilitation Project is to address the impacts of historical dredge mining on aquatic habitat conditions. The Crooked River Valley Rehabilitation project was designed to be constructed in 4 - 6 Phases. The Phases include building a bypass channel, rebuilding floodplain and river channel, and adding large wood structures. Phase 1 Bypass work was completed in 2016, Phase 2 Bypass work was completed in 2017, Option 2 was completed in 2017, and Phase 1 was completed in 2018. The project is being performed on the Red River Ranger District of the Nez Perce Clearwater National Forests in collaboration with the Nez Perce Tribe Watershed Program and funded by Bonneville Power Administration. The project area is located approximately 45 mi east of Grangeville, Idaho. At the junction of Highway 14 and the Crooked River Road (FR 233), travel south for approximately 0.25 mile to the project area.


This contract requires completion of Phase 2 of the Crooked River Valley Rehabilitation Project. Contractor shall construct 50' of temporary haul road which will serve as a plug between the bypass channel and Crooked River. 18 acres of tailings piles shall be regraded and fill material shall be imported from an existing staging area. The contractor shall construct 3,100 feet of new river channel with pools, riffles and channel features. Stockpiled slash shall be spread on along 10 acres of floodplain to provide roughness. The contractor shall perform survey and construction staking and shall survey floodplain and river grades periodically throughout construction to verify elevations. During channel construction, riverbed fill and streambank material shall be sorted or screened to meet gradation specifications if suitable material is not found. The contractor shall furnish all labor, equipment, structures, supervision, transportation, operating supplies (except those designated at Government-furnished), and incidentals necessary to complete the project as required by the contract, plans, and specifications.

Approximately 61,900 cubic yards of tailings piles will be graded and an additional 8,100 cubic yards of tailings shall be imported from the existing stockpile to meet grading requirements and final floodplain elevations. The contractor shall complete maintenance of the haul route internal to the project. Depressions, swales, side channel and wetland features shall also be constructed. Vegetation and trees (including rootwads) shall be salvaged from the work area and stockpiled. Brush and small wood shall be placed on approximately 10 acres of the floodplain upon completion of the regrading to protect the floodplain during high flows.

Government lead fish salvage operations will occur in over one mile of river channel. The government estimates that this operation will take approximately 5 days. The Contractor shall assist the government in its fish salvage efforts by reducing flows in the main stem channel, pumping large pools, and maintaining low turbidity levels. In addition, the Contractor shall excavate the existing plug between the upper and lower bypass channels and plug the gap in the haul road where the upper bypass channel currently empties into Crooked River.

Prices for two additive bid items shall be solicited for the following work items: 1) the construction of up to 18 large woody debris structures and 2) haul of up to 3,000 CY of material to or from the stockpile site. Award of this work will be made concurrent with award of the base items of work. The amount of additive work awarded will be dependent upon funding availability.

The Government's construction estimate is between $500,000 and $1,000,000. A formal pre-bid tour will be held on 4/30/2019; details have been provided in the solicitation.  Construction work shall commence approximately July 1, 2019; all work shall be completed by October 31, 2019. All in-stream work to dewater the main channel and activate the bypass channel shall be performed after July 15, 2019.

Original bid bonds are required.  The solicitation was issued 4/17/2019 with offers due on 5/16/19.  Amendment was done 4/18/2019 to correct organized site visit meeting time.  A second amendment was done 5/7/2019 to address a few issues brought up at the site tour held 4/30/2019.  Site Tour Notes and Responses to Questions were also posted at this time.  The response deadline for offers was not extended.
