The TriMet park and ride lot  on SW Barbur Boulevard and Capitol Highway has a large amount of impervious area. Environmental Services worked with the Oregon Department of Transportation and TriMet to construct parking lot swales to capture and filter stormwater runoff. The swales protect water quality and aquatic habitat in Tryon Creek. The project was completed in 2013.
