City of San Leandro <br />880 Doolittle Drive Industrial Project <br /> <br />ES-8 <br />Impact Mitigation Measure (s) Residual Impact <br /> nesting bird survey no more than 14 days prior to <br />initial disturbances in the work area. The survey shall <br />include the entire area of disturbance area plus a 50- <br />foot buffer (relevant to non-raptor species) and 300- <br />foot buffer (relevant to raptors) around the site. If <br />active nests are located, all construction work shall <br />be conducted outside a buffer zone from the nest to <br />be determined by the qualified biologist. The buffer <br />should be a minimum of 50 feet for non-raptor bird <br />species and at least 300 feet for raptor species. <br />Larger buffers may be required and/or smaller <br />buffers may be established depending upon the <br />species, status of the nest, and construction <br />activities occurring in the vicinity of the nest. The <br />buffer area(s) shall be closed to all construction <br />personnel and equipment until the adults and young <br />are no longer reliant on the nest site. A qualified <br />biologist shall confirm that breeding/nesting is <br />completed and young have fledged the nest prior to <br />removal of the buffer. <br /> If construction activities in a given work area cease <br />for more than 14 days, additional surveys shall be <br />conducted for the work area. If active nests are <br />located, the aforementioned buffer zone measures <br />shall be implemented. <br />Cultural Resources <br />Unanticipated archaeological <br />deposits could be encountered and <br />damaged during ground-disturbing <br />activities required for project <br />construction. Impacts to <br />archeological resources would be <br />reduced to less than significant with <br />implementation of Mitigation <br />Measure CR-1. <br />CR-1 Unanticipated Discovery of Cultural Resources. In <br />the event that archaeological resources are unexpectedly <br />encountered during ground-disturbing activities, work <br />within 50 feet of the find shall halt and an archaeologist <br />meeting the Secretary of the Interior’s Professional <br />Qualifications Standards for archaeology (National Park <br />Service 1983) shall be contacted immediately to evaluate <br />the find. If the resource is determined by the qualified <br />archaeologist to be prehistoric, then a Native American <br />representative shall also be contacted to participate in the <br />evaluation of the resource. If the qualified archaeologist <br />and/or Native American representative determines it to <br />be appropriate, archaeological testing for CRHR eligibility <br />shall be completed. If the resource proves to be eligible <br />for the CRHR and impacts to the resource cannot be <br />avoided via project redesign, a qualified archaeologist <br />shall prepare a data recovery plan tailored to the physical <br />nature and characteristics of the resource, per the <br />requirements of CCR Guidelines Section 15126.4(b)(3)(C). <br />The data recovery plan shall identify data recovery <br />excavation methods, measurable objectives, and data <br />thresholds to reduce any significant impacts to cultural <br />resources related to the resource. Pursuant to the data <br />recovery plan, the qualified archaeologist and Native <br />American representative, as appropriate, shall recover <br />and document the scientifically consequential information <br />that justifies the resource’s significance. The City shall <br />review and approve the treatment plan and <br />archaeological testing as appropriate, and the resulting <br />documentation shall be submitted to the regional <br />Less than <br />significant.
