Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2018-0220-R3, pursuant to Section 1602 of the Fish and Game Code to Marin Country Club. The project is limited to removing approximately 22.7 cubic yards of material from the failed left (north) bank of Arroyo San Jose Stream and stabilizing the undermined section. To stabilize the bank, the applicants will install vegetated soil lift (VSL) that is approximately 37-feet long with an underlying rock toe. Construction also includes excavating keyway between 2 and 3 feet deep which will be filled with 2 to 3-foot diameter boulders. The applicant will have nine VSLs installed that are 12-inches thick installed at varying slopes between ratios of 1.5:1 and 1.8:1. Additionally, construction includes installation of Geosynthetic Reinforced Slope (GRS) which incorporates 8-inch compacted soil lifts reinforced with bi-axial geogrid. lnstream pond 3 at the project site will be dewatered if water is present during time of work. Large woody debris will be added to VSL rock toe, including the Quercus agrifolia that collapsed into the stream and two 12-18-inch root wads. These elements will be secured using 5/8-inch rebar pins and counterweighted by revetment boulders. Exposed soil at this project site, including the exposed steps of the VS Ls will be seeded with native erosion control mix.
