05/08/2017 The buffer shall remain in place until construction is completed. If the roost is in vegetation or a structure that is planned to be removed, the qualified biologist shall work with CDFW to devise a plan to exclude the bats if removal of the roost cannot be avoided. Impact: 13I0-3: Project construction could impact San Francisco dusky -footed woodrat, a California species of special concern. Mitigation: 113I0-3: Not more than thirty (30) days before initial ground disturbance on the project site, a qualified biologist shall conduct a survey of the project site for any existing woodrat houses. If any woodrat houses are found within the project site, they shall be identified with flags or marking tape and protected from disturbance with a minimum buffer zone of five feet around the house. If avoidance is not feasible, the qualified biologist will contact CDFW with a proposal for removing the woodrat house(s) using methods acceptable to CDFW. Currently, the method requires that a biologist with a scientific collection permit trap the woodrats, dismantle their house, relocate the house materials onto constructed artificial houses in nearby suitable habitat that will not be disturbed, and release the woodrats into the artificial house. Woodrat relocation would occur outside of the rat maternity season and when there is no rain and nighttime temperatures are greater than 40 degrees Fahrenheit. This mitigation measure shall be performed under the direct supervision of a biologist approved for this project by the CDFW. Finding: Implementation of Mitigations BI0-1, 13I0-2 and 13I0-3 would reduce the project - related impact to nesting birds, protected bat species and dusky -footed woodrat during construction to a less than significant level. Facts in Support of Finding: These mitigation measures are consistent with best management practice to survey the site prior to tree removal and ground disturbance for the presence of bird nests, dusky -footed woodrat nests, or colony bat roosts. If active bird nests, dusky -footed woodrat nests, or colony bat roosts are found, a construction -free zone shall be established. These measures shall be performed under the supervision of a qualified biologist in consultation with the California Department of Fish and Wildlife. The measures shall remain in place until young birds have fledged in the case of native birds or until construction is complete for any colony bat roosts and dusky -footed woodrat nests. Impact: 13I0-4: The proposed project would result in the removal of approximately 66 native trees and 1 non-native tree. Mitigation: 13I0-4: Prior to project grading all areas of disturbance including pipeline alignments shall be surveyed and staked and a field count performed to confirm the exact number of trees to be removed. Consistent with routine CDFW guidelines, the approximately 66 native trees to be removed by the project - shall be replaced in kind at a 3:1 ratio throughout the project site, including Parcel 1, the scenic easement parcel. In addition, the one non-native tree expected to be removed shall be replaced at a 1:1 ratio. Replacement trees shall Page 5 of 28 ATTY/ RESO.0043/CC RESO HILLSIDE ALTERNATIVE PROJECT RESO.
