Beaverton Hillsdale Highway Water Quality Improvement Project

photo of location of a future swaleEnvironmental Services is early in the planning stages for a water quality improvement project along 2.6 miles of Beaverton-Hillsdale Highway from SW Sunset Boulevard west to the Portland city limits at SW 65th Avenue (see map). 

When it rains, stormwater runs off Beaverton-Hillsdale Highway, or flows through storm drains and pipes, directly into Fanno Creek. The creek flows next to the highway for several miles. Untreated stormwater runoff carries oil, dirt and other pollutants directly into Fanno Creek without treatment.

Environmental Services is working with the Portland Bureau of Transportation and neighborhood groups on this project to maximize opportunities on this major roadway to capture and clean stormwater runoff and improve water quality and stream health in Fanno Creek. Check back here for more information as the project moves through the design stage toward construction.
