The Wilsonville Area Pipeline Project is a 3.3-mile section of the overall 30-mile Willamette Water Supply System pipeline that is being built in close coordination with the City of Wilsonville. The pipeline is comprised of three segments.
Construction is planned to occur in stages, with traffic control changing as work moves through the area. This approach will enhance safety by having smaller work areas to manage and minimizing traffic and community disruptions.
Aside from the pipeline work, crews will also install community improvements in some areas by upgrading some crosswalks, installing a turn lane for Northbound Kinsman Road at Wilsonville Road to alleviate traffic congestion and improve public safety, and install other improvements.
- Phase 1, Wilsonville Road (PLM_1.1), is planned to begin in fall 2019, with completion anticipated in 2020. This portion of the project begins at Arrowhead Creek near the entry to the Willamette River Water Treatment Plant and ends near Wilsonville Road.
- Phase 2, Garden Acres to 124th (PLM_1.2), is planned to begin in summer 2019, with completion anticipated in 2021. This portion of the project begins just south of Garden Acres and Ridder roads and ends near Day Road. This phase of the pipeline is an opportunity project with the City of Wilsonville.Staff from the City of Wilsonville and Willamette Water Supply Program have been coordinating closely to design and build the Willamette Water Supply pipeline with the City of Wilsonville’s Garden Acres Road half street improvements. The street improvements will support Wilsonville’s economic development efforts of the Coffee Creek Industrial Area. Combining the pipeline and street improvements into one well-coordinated effort will reduce the number of construction project impacts and save money through sharing costs.

- Phase 3, Wilsonville Road to Garden Acres (PLM_1.3), is planned to begin in 2020, with completion anticipated in 2022. This project will tie together the remaining portion of pipeline through Wilsonville, utilizing an alignment along Kinsman Road, Boeckman Road, 95th Avenue, and Ridder Road.
