This $260,000 project created about 120 acres of tidal salt marsh utilizing dredged material removed from along
the west side of the Calcasieu River and Pass Ship Channel in Calcasieu and Cameron Parishes, Louisiana. The marsh
creation site was a high quality area that, as a result of salinity intrusion caused by channelization and
subsidence, had severely eroded . About 20 percent of the area was deteriorated marsh and the rest was open water,
one-third of which was less than one foot deep.
Planning, design and construction activities for this project utilized the Corps authority under Section 1135,
WRDA'86, which provides for the modification of existing water resource structures and/or operations for the benefit
of the environment in the public interest. The USFWS provided the necessary lands, easements, and rights-of -way by
virtue of the marsh creation site being on a Federal refuge. The Louisiana Department of Natural Resources was the
non-federal sponsor providing 25% of the costs. Project costs represented the difference in costs of creating the
marsh with dredged material from a maintenance dredging operation from the cost of disposing the material in a
confined disposal site.
