Responsible Monitoring/Reporting Monitoring/ Party for Providing Timing Mitigation Measures and statements of Findings of Impacts Being Reporting Action Responsibility Significant and Unavoidable Mitigation SJMSCP. d. Propose an alternative mitigation plan,consistent with the goals of the SJMSCP and equivalent in biological value. Union Pacific San Joaquin County Prior to project construction BIO-1 b:Burrowing Owl Avoidance Measures.The project applicant shall Verification by County. Community Development activities implement the measures listed below for grassland habitats to reduce potential Department and San impacts to a less-than-significant level and to avoid incidental take of burrowing Joaquin Council of owls.Measures shall apply to all construction activities near active nests or Governments if participation within potential burrowing owl nesting habitat,to avoid,minimize,or mitigate is sought in the SJMSCP impacts on burrowing owls. 1. The applicant shall follow the current CDFG burrowing owl survey guidance, j i.e.the Burrowing Owl Consortium multi-phase approach to evaluate burrowing owl use(California Burrowing Owl Consortium,1993)and the California Department of Fish and Game's staff Report on burrowing owls j (CDFG,1995). 2.An initial breeding season survey shall be performed to determine the presence of burrowing owls for the purposes of inventory,monitoring, avoidance of take,and determining appropriate mitigation.In California,the breeding season begins as early as February 1 and continues through August 31.Under the Burrowing Owl Consortium's multi-phase survey methodology,for areas within 500 feet of construction boundaries (regardless of property boundary),the applicant shall: a. Perform a habitat assessment to identify essential components of burrowing owl habitat,including artificial nest features; b. Perform intensive burrow surveys in areas that are identified to provide suitable burrowing owl habitat;and c. Perform at least four breeding season surveys during the breeding season,from February 1 through August 31 to document habitat use. 3. Pre-construction surveys shall be used to assess owl presence before site modification is scheduled to begin.Initial pre-construction surveys should be conducted within 7 days,but no more than 30 days prior to ground- disturbin activities.Additional suryeys may be required when the initial 9 -> -e:iS;:r r•nl;,r:,:.` t _i .r .c h 2 f'�,i 19 A t 46 al Re'soUtces Biologic ....r:.u:•i_� F,. 11 disturbance is followed by periods of Inactivity or the development is phased spatially and/or temporally over the project area.Up to four or more survey visits performed on separate days may be required to confirm that site modification and grading would not take owls.A follow-up report shall be provided to the CDFG by the surveying biologist. 4. Construction exclusion areas(e.g.,with orange exclusion fence and signage)shall be established around occupied burrows,where no disturbance shall be allowed.During the nonbreeding season(September 1 through January 31),the exclusion zone shall extend at least 160 feet around occupied burrows. During the breeding season(February 1 through August 31),exclusion areas shall extend 250 feet around occupied burrows. a. If work or exclusion areas conflict with owl burrows passive relocation of
