Introduction Mill Creek Wetland Enhancement Site Purpose: develop solutions to ecosystem degradation in the Meadowlands at a watershed scale
Key Project Participants The Public Non-Federal Sponsor New Jersey Meadowlands Commission Lead Federal Agency U. S. Army Corps of Engineers Cooperating Agencies U.S. Fish and Wildlife Service N.J. Department of Environmental Protection National Oceanic and Atmospheric Administration
Study Authority Resolution of 15 April 1999: “Resolved by the Committee on Transportation and Infrastructure of the United States House of Representatives, That, the Secretary of the Army is requested to review the reports of the Chief of Engineers on the New York and New Jersey Channels…with a view to determining the feasibility of environmental restoration and protection relating to water resources and sediment quality within the New York and New Jersey Port District, including but not limited to creation, enhancement, and restoration of aquatic, wetland, and adjacent upland habitats.”
