This corner was the site of the original sawmill that gave the community its name. It's unclear whether some archeological study needs to be done before work proceeds.

Cedar Mill Project Helps Improve Water Quality

The Cedar Mill Falls Swale project improves water quality by filtering stormwater runoff from approximately 66 acres upstream of NW 119th Avenue. The project covers 1.6 acres near the historic Cedar Mill site and Cedar Mill Creek Waterfall at the corner of NW 119th Avenue and NW Cornell Road. 

The project includes a water quality manhole, 40 feet of storm pipe, a 5,000 square foot bio-retention swale and landscape restoration.  The swale design mimics the natural setting by incorporating rock outcroppings and a meandering stream channel.  At the project site, on both sides of Cedar Mill Creek, invasive species will be removed and replaced with native plants.

Cedar Mill Creek flows out of what used to be the millpond and runs through a culvert beneath Cornell before it cascades over the falls.

The project is a partnership between the City of Beaverton, Washington County and Clean Water Services and is scheduled to be complete in November 2013. For more information, contact project manager Jadene Stensland at (503) 681-3662 or stenslandj@cleanwaterservices.org
