Development of South Hillsboro, a 1,400-acre mixed-use community, requires coordination between multiple agencies and infrastructure projects. The Willamette Water Supply Program (WWSP) is coordinating with the City of Hillsboro, Washington County, and private developers to install the portion of the Willamette Water Supply pipeline that will serve the City of Hillsboro. To date, approximately 15,000 linear feet of the Willamette Water Supply pipeline has been installed in coordination with South Hillsboro projects.
Construction of the final section of the South Hillsboro pipeline project is underway as part of Washington County’s Cornelius Pass Road widening project. This section, approximately 3,800 linear foot between the Cornelius Pass Road and TV Highway intersection and Frances Street, is expected to be complete in December 2023.
The coordinated construction of the pipeline and the Cornelius Pass Road improvements and extension saves money, reduces community and neighborhood impacts, and minimizes the need for multiple construction projects.
