DESCRIPTION
Ducks Unlimited (DU) prepared a feasibility study to answer key questions and concerns about the feasibility of reconnecting Meadowbrook Creek to the Dungeness River in Sequim, WA, which would have the potential to influence over 50 acres of floodplain habitat. The river itself and associated tributaries support many species of anadromous fish including fall Chinook, coho, pink, summer chum, steelhead, bull trout, and cutthroat as well as many species of migratory birds including shorebirds and waterfowl. To develop a preferred alternative for restoration, DU contracted with Battelle Memorial Institute to conduct hydrodynamic analyses of the creek and to model three proposed restoration alternatives. The results of this comprehensive modeling are contained in the Meadowbrook Creek Feasibility Study Final Report.
The Battelle Hydrodynamic Evaluation indicated that none of the proposed alternatives would allow for a positive response to the primary project concern regarding existing flooding of adjacent landowners. The report stated that under any proposed alternative, "there are conditions under which tidal exchange would likely be reduced, including during extreme high tides and during neap tidal periods." These are the conditions that result in flooding of adjacent landowners currently. Any reconnection efforts would likely invite liability to project sponsors. DU therefore concluded that the potential flooding risks of reconnecting Meadowbrook Creek to the Dungeness River could not be fully mitigated nor addressed with what DU considers reasonable contingency planning.
