Sonoma Creek Bank Repair
Document Type
NOE - Notice of Exemption
Document Description
The applicant proposes to stabilize a stream bank along Sonoma Creek in Glen Ellen. During the storm event of New Year's 2005-06, some of the bank eroded way and has been unstable ever since. The applicant proposes to stabilize approximately 60 feet of stream bank using bio-technical approaches. The applicant proposes to construct a post and wire revetment fence that will run parallel and adjacent to the bank, with approximately two feet of separation between the fence and the bank. The applicant will use a hydraulic hammer to drive in steel galvanized steel posts (2 inches in diameter by 8 feet lone). These posts will be spaced approximately every four to five feet, and will provide a frame for a galvanized mesh wire fence (2-inch X 4-inch). Collectively the fence and galvanized posts shall be properly anchored to a location higher up on the bank. Native soil and gravels will be backfilled between stream bank and the galvanized fence. A coir blanket (e.g. North American Green CB125) will be properly placed between the galvanized fence and the native fill material. This blanket will be properly anchored such that the blanket will not fail during high flow events. Native plants such as willow, red alder, box elder, snowberry, dogwood, and Santa Barbara sedge will be planted throughout the galvanized fence and the top of the native fill material. Issuance of Streambed Alteration Agreement Number 1600-2008-0355-03 is pursuant to Fish and Game Code Section 1602.
