This design seeks to actively restore properly functioning floodplain and channel conditions within the lower one mile of Big Beef Creek, while maintaining the waterline and the UW capital facilities. The design proposes a large scale restoration project, in two phases. Phase I will minimize the road prism and remove two shop buildings and fill material. Additionally it will involve modifying the well access road to allow several side channels and wetlands to reconnect with Big Beef Creek and allow the stream to utilize more of its floodplain. Phase II will involve instream habitat improvements by installing and/or reinforcing about 20 new or existing log jam structures, adding complexity to the system. Big Beef Creek is one of three watersheds which had subpopulations of summer chum salmon extirpated but recently reintroduced as a cornerstone strategy to recovering this federally-listed ESA species in Hood Canal and the Eastern Strait of Juan de Fuca. Habitat capacity in lower Big Beef Creek where summer chum salmon spawn, incubate, and rear is relatively poor given the stream straightening and simplification that occurred in 1969 and the removal of persistent woody debris. In addition, an access road on a raised foundation to a series of wells providing water for the University of Washington's Fish Research Facility has not allowed the stream to passively recover from channel simplification, except when extreme flood events allow overtopping into a significant floodplain complex and 10+ acre wetland. Additionally, this project implements a corrective action in a treatment watershed of the Hood Canal IMW program, partnering with WA Ecology and Fish & Wildlife to implement validation monitoring. HCSEG hired a team of consultants led by ESA (Engineering Services and Associates) who conducted field surveys and modeling which included a geomorphic assessment by Cardno ENTRIX and a hydrologic assessment by Doug Johnson, P.E. This consultant team proposed several alternative designs, upon which a team of stakeholders selected an option with the most certainty and benefit to the system. The proposed design is explained within the Preliminary Engineering Design Report (a 30% design) which can be found as an attachement in PRISM.
