Pla►rtings sh- ll have a minimum 80%survival after the first year, arid 100 910 survival thereafter; or shall have attained a 75% cover after three "ears and a 90% cover after five years. Plantings shall he monitored each year and maintained as necessary until success criteria have been met. In order to assure implementation, the Wetlands Mitigation Monitoring Plan shall be modfi ed to include these criteria. 65 Austin 2000 (Fix) A 4.3 -acre detention basin will be constructed in the southwest corner of the project site, as depicted on the project plans (Beck 1993). 66 Austin 1994 (F2. a) (similar), Austin 2 00 0 (F2. a) Under current project plans, 31 ofthe 32 valley oaks are along the perimeter of the site or are in the designated wildlife preserve adjacent to the creek and ~Mould not be removed. 67 Austin 1994 (F2. b) (similar), Austin 2000 (F2. b) Prior to initiation of any actin ti- - sithin a 100 foot radius of a valle}• oak proposed for retention, theproject proponent shall install clearly visible temporary fencing around the dripline ofthe Valley oak to prevent inadvertent damage during on-site activities. Fencing shall be removed upon completion of activity within the oak's vicinity. Site workers shall be advised ofthe sensitivity of on -sate oaks to disturbance. 68 Austin 1994 (F2 c) (similar), Austin 2000 (F2. c) Kere avoidance of a valley oak(s) as specified above is detennined infeasible, the project Proponent shall replace each oak as required by the County's Natural Reses ourc Regulalians: three oaks shall beplanted in appropriate locations for each oak removed Replacement trees shall be the saute species as the removed trees. Replacement trees shall be planted on the site in association with the Wetland Mitigation and Monitoring Plan described above. 69 Austin 1994 (F2. d) (similar), Austin 2000 (F2. d) To ensure the success of mitigation, planted and retained trees shall be monitored for a period offive years following inrrial disturbance within the vicinity of a retained tree or following planting of a replacement tree. If, during the course of monitoring, a significant decline in the health of planted or retained trees is identified by a qualified arborist, the tree shall be replaced as described ahove. 70 Austin 1994 (F3, a) (similar), Austin 2000 (similar) (F3. a) Of the 219 acres disturbed, a 10.5 --acre wildlife preserve and flood foraging habitat. plain will be retained as
