Environmental Services is designing a project along 2.6 miles of Beaverton-Hillsdale Highway to improve water quality and stream health in Fanno Creek. Work will take place in phases at various locations between SW Sunset Boulevard and the Portland city limits at SW 65th Avenue (see map).
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.
In the first phase of construction, Environmental Services will work at one location to install underground vaults and above ground green street planters 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.
Environmental Services is working with the Portland Bureau of Transportation and neighborhood groups on project design. We will continue to provide updates and give the public opportunities to comment as project design continues.
