A variety of projects in other regions have used dredge materials to build or elevate marsh plain. This type of habitat enhancement work has a limited record in Puget Sound, possibly including a few small sites in urban estuaries. Jetty Island, Everett, has been built by dredged sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment., and includes a spit behind which some saltmarsh is developing. Eelgrass has been planted on fill material in limited places in Puget Sound, per Ron Thom. Are there any other examples out there?

Examples

Coos Bay, Oregon

  • South Slough Estuarine Research Reserve: http://www.oregon.gov/dsl/SSNERR/docs/WTRPkunzpart1.pdf Though they didn't use dredged sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment., at the Kunz Marsh old dike material was used as fill to experimentally manipulate marsh elevation of the subsided restoration site. The site was divided into four experimental zones receiving different levels of fill material.

San Francisco Bay

  • Hamilton Wetlands: http://hamiltonwetlands.scc.ca.gov/ Old military air base restored to marsh using dredged sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. to raise the subsided site prior to dike breaching.
  • Montezuma Wetlands Restoration Project: http://ceres.ca.gov/wetlands/projects/montezuma.html Restoring about 1,800 acres of tidal wetland by using dredged sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. to bring diked/subsided area up to natural elevation before breaching dikes.
  • Sonoma Baylands: http://www.bay.org/bay-restoration/restoration-projects/sonoma-baylands Restored ~360 acres tidal wetland by using dredged sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. to fill a diked/subsided area before breaching dikes.

The Army Corps of Engineers is the lead federal agency for sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. dredging and beneficial re-use, and they maintain a Dredge Material Management Program website. Their User Manual for Dredged Material Evaluation and Disposal Procedures has been developed for Washington state.

The Washington Department of Natural Resources is the state agency overseeing dredging, and their Dredged Material Management Program provides many resources and contacts.
