About this file
The file is a detailed set of road reconstruction plans for the Willamette National Forest's BCLH Stewardship IRSC Phase 3 project, specifically Appendix D containing engineering drawings and technical specifications. The plans cover reconstruction of base and optional roads in the Detroit Ranger District, including comprehensive details on road structure, drainage systems, fill repair techniques, disposal areas, and soil erosion control. Technical drawings provide specific guidance on road reconstruction methods, including typical road cross-sections, culvert installation types, wire facing details, and disposal area configurations, with specific attention to managing terrain in areas affected by the 2020 Beachie Creek and Lionshead Fires.
The technical drawings outline precise engineering specifications for road restoration, featuring detailed diagrams for roadway elements such as turnout reconstruction, ditch drainage, culvert installations, and slope stabilization. Specific technical details include road prism management, slope angles (ranging from 1:1 to 2:1), drainage system configurations, and prescribed methods for soil and erosion control. The plans emphasize maintaining existing road characteristics while implementing reconstruction, with particular focus on managing water flow, preventing erosion, and ensuring structural integrity in fire-damaged terrain within the Willamette National Forest's project area near Detroit, Oregon.
