Document Description
The project is along a 0.4-mile reach of Marsh Creek in Brentwood. The site includes the existing on-site inoperative dam, the proposed staging area, and proposed access road. The goal is to return the stream to a form that is protective of archaeological and biotic resources in the area. The project includes retrofit of the inoperative dam including cutting and removing four large sections of the dam and filling and reshaping the eroded plunge pool. The southern bank of the downstream site of the dam would be filled with soil and reinforced. The rebuilt and reshaped banks would be lined with rock and riparian plantings to armor the newly restored banks. Construction would occur over 18 weeks and revegetation and maintenance would occur over approximately 36 months.
