Flume Creek Culvert Replacement and Channel Restoration at Boundary Road (County Road 2975). The City of Seattle is seeking qualifications for this project. Qualifications must be submitted via the e-procurement portal. Questions should also be submitted through the same portal. Question Deadline 01/20/2026 at 4:00 PM PT Respondents may submit their questions through the Procurement Portal or Ned Lichty, Sr. Contracts & Procurement Specialist, ned.lichty@seattle.gov, (206) 386- 1759 Seattle City Light (City Light) owns and operates the Boundary Hydroelectric Project on the Pend Oreille River in northeast Washington near the town of Metaline Falls. In March 2013, FERC issued a 42-year license to City Light. The License and associated settlement agreement requires City Light to implement stream habitat improvement measures in tributary streams that flow into Boundary Reservoir (Pend Oreille River) as described in the Fish and Aquatic Management Plan (FAMP). Protection, mitigation, and enhancement (PM&E) measures provided in this plan include replacing the culvert on Flume Creek at Boundary Road (County Road 2975) with a fish passable structure and placement of large woody debris (LWD) along Flume Creek. Implementation of these measures will also require restoration of the affected area involving sediment management, floodplain restoration including wetlands, channel realignment, installation of engineered log jams (ELJs), and revegetation with native plantings. A remnant, impounded reservoir occurs on the upstream (west) side of Boundary Road. This impoundment is a relict feature of mining interests (Josephine Mill/Mine and Pend Oreille Mines and Metals) in the area which used the water from Flume Creek to generate power and refine ore. The original operators of the mines employed various means of impounding and diverting water at the site including using Boundary Road as a dam and installing various structures including wooden weirs, pipes, and water control gates. The impoundment is approximately 5.8 acres and extends 1,500 feet upstream of Boundary Road. Since mining companies abandoned the area, the impoundment has filled in with sediment which supports extensive wetland habitat.
