Engineers Corps September 24, 2010 – Federal Register Recent Federal Regulation Documents

Pursuant to Section 102(2)(C) of the National Environmental Policy Act (NEPA) of 1969, as amended, the U.S. Army Corps of Engineers (USACE) will prepare an Integrated Feasibility Report/Environmental Impact Statement (FR/EIS) for proposed ecosystem restoration and flood risk management in the Skokomish River Basin which empties into Hood Canal, near Shelton, Washington. The Skokomish Indian Tribe and Mason County are the non-Federal sponsors for the project. The Skokomish River General Investigation (GI) Feasibility Study for the Skokomish River Basin is being conducted under the authority of Section 209 of the Flood Control Act of 1962 (Pub. L. 87-874). The Skokomish River channel has been filling with sediment for several decades, resulting in frequent flooding and decreasing natural ecosystem structures, functions, and processes necessary to support critical fish and wildlife habitat throughout the Skokomish River Basin. Increased sediment load, reduced flows, and encroachment of the floodplain by man-made structures are leading to continued degradation of natural ecosystem functions and habitat. The degraded riverine and estuarine aquatic habitat has caused a decline in the population of critical fish and wildlife species, including multiple ESA listed species. Additionally, the channel capacity of the Skokomish River varies significantly. Limited channel capacity causes floodwater to leave the banks at various locations, ultimately causing frequent flooding of local roads, two state highways, agricultural fields, residences, and other structures. The Skokomish River GI is a basin-wide study; however, work by others, constrain the limit of Corps' involvement to actions primarily in the lower Skokomish River Valley. Problems, opportunities, and objectives will be examined within the context of the entire watershed. Recognizing the relationships between the upper and lower watershed will ensure a comprehensive study overview. The purpose of the FR/EIS and feasibility study is to evaluate if there is a federal interest in aquatic ecosystem restoration and flood risk management in the Skokomish River Basin.
