Consolidated Forward :. Landfill Page 18 <br /> Rodenticides and methods of application used at the landfill shall be reviewed by a qualified <br /> biologist to determine if they reflect the most effective and safe ruethods for controlling <br /> rodents. That biologist shall make recommendations for improvement if needed. { <br /> 63 Austin 1994(FIx,Fl.b,and Fl.e) (similar but updated),Austin 2000(Fl.a) <br /> (Creek realignment)Monitoring and maintenance for five years follo►ving construction. <br /> 64 Austin 2000(F].c) <br /> Restoration of the riparian area shall include revegetation with trees,shrubs, and grasses <br /> native to the area. Plantings shall have a minimum 80%survival after the first year, and 100 <br /> %survival thereafter;or shall have attained a 75%cover after three nears and a 90%cover <br /> afterfiveyears. Plantings shall be monitored each year and maintained as necessary until <br /> success criteria have been met_ In order to assure implementation, the TI'etlands Mitigation <br /> and Monitoring Plan shall be modified to include these criteria. <br /> 65 Austin 2000(Fl.a) <br /> A 4.3-acre detention basin will be constructed in the southwest corner of the project site, as <br /> depicted on the project plans(Beck 1993). <br /> 66 Austin 1994(F2.a)(similar),Austin 2000(F2.a) <br /> Under current project plans, 31 of the 32 valley oaks are along the perimeter of the site or <br /> are in the designated wildlife preserve adjacent to the creek and would not be removed <br /> 67 Austin 1994(F2.b)(similar),Austin 2000(F2.b) <br /> Prior to initiation of any actiiih•i,,ithin a 100 foot radios of a valley oak proposed for <br /> retention,the project proponent shall install clearly visible temporary fencing around the <br /> dripline of the Valley oak to preiwnt inadvertent damage during on-site activities. Fencing <br /> r <br /> shall be removed upon completion of activity within the oak's vicinity. Site workers shall be t <br /> advised of the sensitivity of on-site oaks to disturbance. <br /> 68A ustin 1994(FZc)(similar),Austin 2000(F2.c) <br /> Where avoidance of a valley oaks)as specified above is determined infeasible, the project <br /> proponent shall replace each oak as required by the County's Natural Resources <br /> Regulations.three oaks shall beplanted in appropriate locations for each oak removed. <br /> Replacement trees shall be the smae species as the removed trees. Replacement trees shall <br /> be planted on the site in assochmaon with the Wetland Mitigation and Monitoring Plan <br /> described above. <br /> 69 Austin 1994(F2.d)(similar),Austin 2000(F2.d) <br /> To ensure the success of mitigation,planted and retained trees shall be monitored for a <br /> period offive years following initial disturbance within the vicinity of a retained tree or <br /> following planting of a replacement tree. If, during the course of monitoring,a significant <br /> decline in the health ofplanted or retained trees is identified by a quaked arborist,the tree <br /> shall be replaced as described above. <br /> 70Austin 1994(F3.a)(similar),Austin 2000(similar) (F3.a) <br /> Of the 219 acres disturbed, a 10.5—acre wildlifepreserve and floodplain will be retained as <br /> foraging habitat. <br /> f <br />
