North Clackamas Revitalization Area – Phase I/II/III

Clackamas County, Oregon

Century West was hired to complete a multi-year project to provide sanitary sewer service to approximately 1,000 homes within an area west of I-205 bisected by Johnson Creek Boulevard for a total estimated project cost of $12,500,000. This project was funded by a combination of sources including the Clean Water State Revolving Loan Fund for the State of Oregon and a $4,000,000 grant/loan as part of the American Recovery and Reinvestment Act of 2009. The first phase included approximately 250 services and construction of 14,000 lineal feet of 8″, 10″ and 12″ sanitary sewer pipe across public right-of-way and nearly 20 private easements. Other facets in this first phase included trenchless construction techniques such as horizontal direction drilling and pipe ramming a steel casing to install the new sanitary sewer pipe beneath Johnson Creek. The project involved conceptual design followed by preliminary design and final design. Construction of Phase I was completed in 2010 when Phase II design efforts for an additional 20,000 lineal feet of 8″ sanitary sewer pipe were also completed. Phase III design efforts for the remaining 15,000 lineal feet of 8″ sanitary sewer pipe were completed in 2011.
