Cedar Mill Creek

Cedar Mill North Johnson water way complimented with many lush green plants and a cloud filled sunny sky.

Infrastructure projects can present the opportunity to work in partnership and include additional improvements at an overall reduced cost. The need to replace an aging pipe in the Cedar Mill Creek watershed provided Clean Water Services with an opportunity to also invest in local environmental and wildlife habitat improvements richly.

The two-year project will replace an over 40-year-old sanitary sewer pipe, which runs through Tualatin Hills Nature Park and enhance the environment around Cedar Mill Creek. The project will help Cedar Mill Creek thrive and will provide cool, clean water as it flows through Tualatin Hills Nature Park to its confluence at Beaverton Creek.

During the construction process, CWS will cut trees in the construction area and will reuse most of them in the later stream enhancement work. The project is designed to protect birds and other wildlife and upgrade several boardwalks and trails to improve park users’ experience. After construction is complete, the area will be replanted with thousands of native plants, trees, and shrubs.

Construction will occur during the summers of 2021 and 2022. Please stay tuned to this site for updates, as there will be trail closures and detours required throughout the project.
