This project will restore hydrologic function and fish passage where freshwater streams enter the estuary of Andrew's Creek, within the Elk River NRCA. This estuary is a nationally recognized wetland system with large, high quality salt marshes, WA Natural Heritage Plan Priority 1 transition zone wetlands, and large freshwater streams and associated wetlands that support water quality in the estuary. The project will remove significant areas of fill from bridge approaches, old road fills and old railroad grades in the tidally influenced areas of Andrews Creek and the Elk River Estuary. Ecological restoration of marshes and wetlands will increase the wetland area of the estuary, and barrier removal will increase habitat available to anadromous fish. After these critical needs are resolved, public use planning can help develop appropriate uses and a trail plan that doesn't impact sensitive resources. The roads to be abandoned in this project dead end on the NRCA and will not affect nearby landowners. The "dike" is a railroad causeway that only affects the NRCA.
