Champoeg Park Dock Revetment
The project consisted of building a vegetated bank revetment consisting of 500CY of boulders, large wood with root-wads and live willow plantings. The challenging aspects of this project included working on a saturated silt riverbank with difficult ingress/egress and the fact thatmuch of the construction was under water in the actively flowing Willamette.
Construction crews removed about 24,000 cubic yards of soil to create more than 13 acre-feet of flood storage. New creek meanders provide an additional 200 feet of cold water spawning and rearing habitat for steelhead, cutthroat trout and coho salmon. Two backwater channels were added along Johnson Creek and one on the new Kelley Creek channel to provide wetland habitat, high flow refuge for fish, and floodwater storage.
Elk Creek Floodplain Restoration
The primary goal of the project was to reconnect old floodplain channels, restore tidal floodplain function, provide refugia for aquatic residence and wildlife habitat.
