| Abstract: | Frequent dredging has been required in the area of the proposed Regulating Works, Dogtooth Bend Phase 5 Construction work area (Dogtooth Bend Phase 5 work area; see a detailed discussion of this in Section 3, Affected Environment.) Therefore, after analysis of this area, the District concluded that construction of the Dogtooth Bend Phase 5 work area is reasonable and necessary to address the repetitive channel maintenance dredging in order to provide a sustainable, less costly navigation channel in this area. The District has concluded through analysis and modeling that construction of river training structures would provide a sustainable alternative to repetitive maintenance dredging. Construction of the Dogtooth Bend Phase 5 work area is proposed to begin in 2014. The planning of specific construction areas, including the Dogtooth Bend Phase 5 work area, requires extensive coordination with resource agency partners and the navigation industry. The U.S. Fish and Wildlife Service (USFWS), Missouri Department of Conservation (MDC), Illinois Department of Natural Resources (IDNR), and multiple navigation industry groups were involved in the planning of the Dogtooth Bend Phase 5 work area to avoid and minimize any impacts on the navigation industry and environmental resources. |
