Culvert_Plan_Sheets.pdf

The document is a set of engineering plan sheets for the Washington County Department of Land Use and Transportation's NW West Union Road Culvert #1601 & #1765 Replacement Project in Oregon, scheduled for Summer 2023. The project involves grading, drainage, structure, and paving work, specifically focusing on replacing two culverts along NW West Union Road. The plan sheets detail the project location, site map, road profiles, construction notes, and technical specifications for culvert replacement, including removing existing culverts, installing new culvert sections, and performing associated roadway modifications.

The project includes multiple technical components such as constructing 10' x 5' reinforced concrete box culverts, installing structural backfill, regrading existing channels, and implementing geotextile and granular materials. The engineering drawings provide detailed station profiles from 99+25 to 101+50 for the West Union Road section and additional profiles for the South Connector. Construction notes specify precise requirements for culvert installation, including removal of existing infrastructure, installation of new culvert sections, and detailed backfill and grading specifications. The project appears to be funded through Washington County's transportation infrastructure budget, with precise engineering and construction details meticulously mapped out across multiple technical plan sheets.
