Potential impacts to San Joaquin Kit A-3 Fox The proponent shall enter into formal consultation with the USFWS prior to the beginning of construction. As part of the formal consultation process, the proponent shall be required to obtain an incidental take permit and prepare a HCP under Section 10(a)(1)(8)of the Federal Endangered Species Act. Mitigation for impacts to potential kit fox habitat presented in the NCP shall include acquiring and preserving suitable habitat off-site. The mitigation preserve acreage shall be protected in perpetuity via a conservation easement or Fee Title transfer of property ownership .r1 Impacts to San Joaquin kit fox shall be mitigated at a 1.1:1 ratio for the total area comprising a 30o- foot wide band extending inward from the outside perimeter on the east and south sides of the project site. Mitigation shall not be required for the north and west sides of the perimeter, which are adjacent to orchards and not expected to provide kit fox habitat.Based on the established mitigation ratio,it will IV be necessary to provide a mitigation parcel of 34.85 acres to mitigate impacts to kit fox. - Mitigation Measure 4.7-2b(A-1,A-2&A-3) m The proponent shall include in the HCP measures to avoid direct loss of the San Joaquin kit fox. These measures shall be consistent with the draft USFWS Standardized Recommendations For Protection of the San Joaquin Kit Fox Prior to or During Ground Disturbance(USFWS, 1997). In addition,measures to minimize the potential for secondary poisoning of kit fox by project and post- reclamation operations shall be implemented, Such measures shall include restricting the use of rodenticides and/or only using zinc phosphide, which has a lower risk of causing secondary poisoning, to control rodent populations. Impact 4.7-3 All Alts. None required. Potential Impacts to Swainson's Hawk Impact 4.7-4 A-4 A-1,A-2& Mitigation Measure 4.7-4a(A-1,A-2&A-3) All Alts. Potential Impacts to Western A-3 Burrowing Owl Within 60 days prior to the beginning of construction activities,or any project activity likely to impact the burrowing owl, the proponent shall retain a qualified biologist to conduct a pre-construction survey of the affected area. If active nesting sites are identified, the proponent shall develop and implement remedial programs in consultation with the CDFG. If no active burrows are found during pre- construction surveys,a letter report documenting survey methodology and findings shall be submitted to the County and CDFG for review and approval,and no further mitigation will be required.
