HighlightsWashington Rock provided streambed cobbles and streambed boulders used for constructing the meandering streambed. In addition to producing our standard cobble mix, we created a custom cobble mix that matches the local stream environment. Our streambed products will provide habitat for fish and other aquatic species.
According to the Port of Tacoma website, the streambed restoration will help to expand and improve “rearing and foraging opportunities for juvenile salmonids.” It will also expand and improve “habitat for shorebirds, waterfowl, and groundfish.”
