A variety projects in the Eastern United States have used dredge materials to build or elevate marsh plain. This type of restoration work has a limited record in Puget Sound (are there any examples out there?). Eelgrass has been planted on fill material in a couple places in Puget Sound, per Ron Thom, but beneficial use appears to be rare in Puget Sound tidal habitats.
