88 and 82 Creek Road Fairfax Creek Bank Repair

The proposed project includes replacement of the entire length of failed retaining wall, at 88 Creek Road, with a new taller reinforced concrete wall placed behind the existing wall. A scour pocked close to the existing wall will be cleaned of debris and filled with 12-inch to 24-inch rip-rap rock placed at a 1.5:1 slope. The proposed work at 82 Creek Road includes installation of a new reinforced concrete wall approximately 35 feet long x 6 feet high as well as removing existing wood extensions at the stream bank and replacing the structures with a reinforced concrete grade beam cap and associated horizontal tie-backs. A sloped bench will be graded above the wall at 82 Creek Road. Rip-rap rock and the upper soil areas will be planted with native species including willows, creek dogwood, white alder and other appropriate species and backfilled with local native alluvium and top soil. The applicants/Operator expects to have to de-water the stream channel at the project site and potentially relocate fish and/or aquatic species to an appropriate area downstream/upstream the project area. The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement number 1600-2007- 0289-3 pursuant to Section 1602 of the Fish and Game Code.
