Recent Projects

Errol Creek ConfluenceColumbia Slough Confluence Restoration

The confluence of the Columbia Slough and the Willamette River is a high priority habitat area for juvenile salmon, as well as other native fish, birds and turtles. This project, completed in early 2010, improves in-stream, riparian and floodplain habitat area.

Stephens Creek Confluence Habitat Enhancement

The Stephens Creek confluence provides critical rearing and refuge habitat for native, endangered salmon and steelhead trout, as well as rainbow and cutthroat trout, and Pacific and brook lamprey. This project, completed in 2008, improves in-stream, stream bank, and floodplain wetland habitat.

Errol Creek Confluence Restoration

Inverness beforeThe Errol Creek Confluence Project, completed in October 2009, removed fish barriers and day-lighted the section of Errol Creek that once flowed underneath SE 44th Avenue. The project improved fish passage between Johnson Creek and Errol Creek, created a longer, more sinuous channel and a backwater channel to provide refuge for fish and flood water storage from Johnson Creek.

SW Marigold Green Street 

Environmental Services completed construction in fall 2008 on this vegetated swale on SW Marigold Street between SW 30th and SW 35th. The curb extension manages over 460,000 gallons of stormwater annually from nearly four acres of impervious surface. This project is just uphill of the Tryon Creek headwaters, and helps slow and filter runoff to prevent pollutants from washing into the creek.

Inverness after

Inverness Wetland Enhancement

This project removed an obsolete culvert and causeway in the southern arm of the Columbia Slough near NE 112th Avenue. The city completed construction in fall 2009, creating revegetated banks and enhanced turtle habitat.
