Document Description
The proposed project restoration efforts focus activities on the left bank immediately downstream of the Magnolia Avenue box culvert and the 200-foot channel reach immediately east of the Lark Creek Inn facilities. Work immediately downstream of the box culvert will consist of stabilizing the toe of the bank with vegetated riprap. This will entail removing the remnants of the existing willow wattle fence and placing approximately 40 linear feet of vegetated riprap to an elevation equivalent to the 2-year flood water level. The riprap will be keyed into the channel bed and bank below scour to form a stable foundation. Riprap will be sized for the 100-year flood flow event. Upslope of the riprap toe, artificially placed debris will be removed and the entire slope backfilled and graded to a 2:1 slope. All surfaces will be revegetated with native, shade-tolerant plants (e.g., Snowberry, Creek dogwood, etc.). In addition to stream bank stabilization and restoration actions, the exposed portion (approximately upper 2-feet) of the downstream gravel bar will be excavated and removed to reduce the size of this geomorphic feature. Issuance of a Streambed Alteration Agreement Number 1600-2006-0619-3 is pursuant to Fish and Game Code Section 1602.
