the fence plan in consultation with the USFWS and shall submit the plan to the City of Pleasanton and the USFWS for review and approval prior to the City's action on the first Final Subdivision Map. The fencing shall be installed 10 days before grading begins and shall be maintained during all grading activities. (ii) Remaining Impacts. Any remaining impacts related to impacts to Alameda whipsnake and its habitat will be less than significant. Impact on Any Riparian Habitat or Other Sensitive Community 7. Impact on Wetlands and Waters of the United States and/or the State of California (DEIR, pp. 108-110, 119-120 and 359/360; Condition 9e of PUD-33; MMIP D8). a. Potentiallmpact. The Original Project's potential impacts due to proposed filling of 2,004 square feet of Section 404 and isolated wetlands and 2,708 linear feet of waters of the U.S. and California in drainages are discussed in the DEIR at page 108-110. The Environmentally Superior Project would reduce these impacts to the proposed filling of 1,171 square feet of Section 404 and isolated wetlands and 145 linear feet of waters of the U.S. and California in drainages. These impacts are discussed in the DEIR at page 359. b. Mitigation Measures. The following mitigation measure is hereby adopted and will be implemented as provided for in the Mitigation Monitoring and Implementation Program: • Implement Oak Grove Planned Unit Development (PUD-33) Mitigation Measure D8. c. Findings. Based on the EIR and the entire record before the City, the City finds that: (i) Effects of Mitigation. To mitigate the potential significant impact on United States wetlands and waters from the proposed filling of Section 404 and isolated wetlands and drainages associated with the Environmentally Superior Project, the project developer shall mitigate the impacts by creating on-site wetlands at a 2:1 ratio, and new drainages on-site at a 1:1 ratio or shall preserve off-site drainages at a 10:1 ratio.
