The government aims to begin construction on the channel and levee in 2027 and is currently evaluating the most effective delivery method, considering design-bid-build, design-build, or a hybrid approach. The project must comply with several environmental mandates, including the National Environmental Policy Act, the Clean Water Act, the Endangered Species Act, and the National Historic Preservation Act, and will require a Project Labor Agreement.
