The operator proposes to install loose rock riprap along approximately 50 feet of bank on Moss Creek in Capell Valley, Napa County, APN 032-430-015-000. The bank stabilization is to protect an existing sewer line that spans the creek. The bottom keyway will be excavated and spoils will be placed outside the riparian zone. A geotextile fabric will be laid in the keyway and up the bank. A bedding of 4-6 inch clean river gravel will be laid, upon which 12-30 inch riprap will be placed. Riprap will be keyed in at the toe and will be placed by a long arm backhoe. Issuance of a Streambed Alteration Agreement Number 1600-2005-0588-3 is pursuant to Fish and Game Code Section 1602.
