DESCRIPTION
The purpose of the feasibility phase of project development was to investigate formulating a solution to address ecosystem restoration. The ACOE did some analysis on flood reduction and determined this project is a ecosystem restoration project. Specific studies have been performed in certain areas of the river for other investigations. The project synthesized and compiled those studies using a gap analysis that will provide a baseline foundational structure for further feasibility implementations. Feasibility investigations included areas for habitat and floodplain enhancement, restoration and acquisition of both fee simple title and conservation easements. Channel migration zones will be identified as well as disturbed or disconnected off-channel areas that may be subjected to re-establishment with floodplain processes. Fluvial and hydrologic modeling was conducted and current channel locations, cross-sections and site specific aggradation of the streambed was analyzed. The watershed hosts three listed stocks of fish including Puget Sound chinook, Hood Canal summer chum and bull trout. This project proposal is one that brings together the Tribe, Mason County, Mason Conservation District, WSDOT, and most critically, provides a funding match for securing additional support from the Army Corps of Engineers. The GI study has completed this feasibly study and will develop a range of restoration actions throughout the Skokomish River including several actions in the confluence reach. Several concepts have been identified in this reach and are included in the excel project spread sheet. The 35% project design will be completed in late 2013 and the EIS will be completed in late 2014.
