Project Plans and Technical Specifications - Oregon Department of Transportation, Union County Brush Creek Channel Repairs

This document comprises engineering plan sheets and construction details for the Brush Creek Channel Repairs project, a stream restoration initiative located along Old Oregon Trail Highway (I-84) in Union County, Oregon, managed by the Oregon Department of Transportation. The project involves comprehensive channel rehabilitation across 34 cells, requiring contractors to remove streambed sediment, install channel sealing materials, grade channel bases, and reconstruct streambed channels using salvaged materials. Specific work quantities detailed in the cell repair tables include sediment removal volumes ranging from 0.5 to 13.6 cubic yards per cell, streambed fill quantities from 11.1 to 44 cubic yards per cell, bentonite layer installation at 0.9 to 3 tons per cell, and Class 200 riprap installation where specified. All work must be completed "in the dry" during the July 1 through October 15 work window, with access to the work area restricted to westbound lanes of I-84 per Traffic Control Plan 56V-072. The project includes two bid alternatives—Option A1 utilizing shotcrete seal material and Option A2 utilizing 30 mil. PVC geomembrane liner—with the contract award determined by the lowest responsive bid combining either Base bid plus Add Alternate 1 or Base bid plus Add Alternate 2.

The plans establish specific environmental and operational requirements, including preservation of existing weirs, concrete liners, and plantings, installation of sediment protection and temporary water management facilities to prevent sediment-laden water from leaving the site, and placement of Type 2 fish rocks (three per cell) as directed. Equipment operating within the stream channel must utilize environmentally friendly operating fluids or approved leak protection. Temporary water management measures include provision for full channel isolation when necessary, dewatering sump pumps with geotextile fabric fish screens, and energy dissipators. The plans were last revised on November 26, 2024, with notes updated to reflect bid alternative changes and revised table units. The project drawings are scaled at 1"=60' for site plans and 1"=20' for cell repair details, with additional sections provided at 1"=5' scale for repair details.
