Beaverton Hillsdale Highway Water Quality Swale

Beaverton Hillsdale Highway has a significant impact on the flows and water quality of Fanno Creek. Stormwater retrofits like the Beaverton Hillsdale Highway swale reduce pollutants in stormwater runoff and protect Fanno Creek water quality. Environmental Services completed this project in 2009.
