been made. The project developer shall conduct a Callippe Silverspot Butterfly survey and shall submit the survey to the USFWS to render a decision regarding the presence/absence of Speyeria callippe callippe and, if present, shall prepare a Callippe Silverspot Butterfly Mitigation and Monitoring Plan. (Mitigation Measure D-3 of the FEIR.) d. To protect Alameda whipsnake populations from possible impacts during construction through direct mortality, a silt-control fence plan shall be prepared in consultation with the USFWS and, if required, shall be installed to the satisfaction of he Planning Director and City Engineer 10 days before grading begins and shall be maintained in place until grading is completed. (Mitigation Measure D-6 of the FEIR.) e. To mitigate the potential significant impact on United States wetlands and waters from the proposed filling of 0.03 acres of Section 404 and isolated wetlands and 145 linear feet - 0.003 acres - of United States waters in drainages, the project developer shall mitigate the wetland impacts in the form of creating on-site wetlands at a 2:1 ratio, and shall mitigate the stream impacts by creating new drainages on-site at a 1:1 ratio, or preserve off-site drainages at a 10:1 ratio. (Mitigation Measure D-8 of the FEIR.) f. To mitigate the potential significant impact on California tiger salamander and California red-legged frog movements to off-site breeding habitats from direct mortality, the project developer shall implement the Hearst Drive wildlife crossing features described in Mitigate Measures D-1 and D-2 of the FEIR. At the discretion of the Planning Director, the above-described information may be combined on a single drawing or combination of drawings or by other means, provided that the information is clear, legible, and able to be used by the reviewing authority in course of rendering its decision. T0~:11. To meet the Mitigation Monitoring and Implementation Measures D-4 and D-5 of the FEIR, the project developer shall perform the following: If grading is scheduled to begin during raptor breeding season as defined by the California Department of Fish and Game, a qualified biologist shall conduct apre-construction survey 30 days prior to the beginning of grading to verify the presence/absence of active raptor nests. The project developer shall implement the discussion points stated in the Oak Grove Draft Environmental Impact Report. The project developer shall retain a qualified biologist to conduct apre- construction survey 30 days prior to the beginning of site grading to verify the presence or absence of burrowing owl nesting sites. The project developer shall implement the discussion points stated in the Oak Grove Draft Environmental Impact Report. Construction shall not take place if it is determined by the biologists that such construction would disturb an identified active raptor nest and/or burrowing owl CitX Council October 2. 2007 Page 4 of 41
