Missouri River Bank Stabilization and Navigation Project. Final Environmental Statement Continuing Construction and Maintenance

摘要

The remaining new construction consists of building a few more structures, mainly in the lower 250 miles of the river, which will complete development of the bank stabilization and navigation project. Maintenance work, which will continue throughout the life of the project, will consist of repair of structures and the addition of occasional new structures to replace construction materials removed by water action and other causes, and to adjust to changing river conditions, respectively. Structure maintenance will be supplemented by occasional dredging to assist in retention of the river channel's full navigational dimensions. Construction of approved river recreational access sites will continue to occur after bank stabilization and navigation development is complete. Individual sites will be built whenever non-Federal sponsors furnish necessary lands to accommodate the development and agree to execute a cost sharing contract for developement and for operation and maintenance of the development. The scope of this EIS is limited to the identification and discussion of impacts of the remaining work, including maintenance, and their effects on the environment of the project area. The statement does not address the impacts and effects of all the work of bank stabilization and navigation that has taken place over the past 60 years.
