Summary

This is a specifications document for the SR 509 Clear Creek Stream Restoration project in Pierce County, Washington, prepared by the Washington State Department of Transportation in coordination with local agencies. The project encompasses the removal of two WDFW-identified dams (IDs: 600317 and 600318) located on Clear Creek south of Pioneer Way East within a former trout hatchery, along with removal of additional stream obstructions and comprehensive stream restoration activities. The scope of work includes installation of a temporary stream diversion system, erosion control measures, clearing and grubbing operations, tree removal, channel excavation, stream grading, placement of large woody material for habitat restoration, and native vegetation planting to restore approximately 1.5 miles of Clear Creek to support salmonid migration and aquatic ecosystem function.

The project is state-funded with established contracting set-asides requiring a 5% condition of award for public works small business enterprises and a 2% condition of award for veteran-owned businesses. The contract specifications establish detailed technical requirements for dam removal sequencing, environmental protection protocols, restoration standards, and material specifications to ensure compliance with regulatory requirements and successful long-term ecological outcomes. Bidders must demonstrate capability in stream restoration, heavy equipment operation, environmental compliance, and restoration planting techniques, with particular emphasis on minimizing environmental impact during construction activities and achieving measurable ecological success criteria upon project completion.
