Beaverton-Hillsdale Highway Water Quality Improvement Project

Updated January 12, 2018

Environmental Services is tentatively scheduled to begin construction in late spring or summer 2018 along Beaverton-Hillsdale Highway to improve water quality and stream health in Fanno Creek. Work will take place between SW 50th and SW 56th. When it rains, stormwater runs off Beaverton-Hillsdale Highway and flows to storm drains and pipes into Fanno Creek. Untreated stormwater runoff carries oil, dirt and other pollutants directly into the creek. This project will improve local and downstream water quality in Fanno Creek.

BHH Project MapProject Information

Environmental Services will install underground vaults and above ground green street planters (removing the right turn lanes heading westbound on Beaverton-Hillsdale Highway) to collect and filter stormwater before it flows into Fanno Creek. This pilot project will test the effectiveness and long-term maintenance needs of the filter vaults. Future construction phases will include installing additional filters and green street planters at other points along Beaverton-Hillsdale Highway.
