construction phasing, construction equipment, and dust control measures, and such plan shall be approved by the Director of Community Development. Air quality construction measures shall include Basic Construction Mitigation Measures (BAAQMD, May 2011) and, where construction-related emissions would exceed the applicable thresholds, additional Construction Mitigation Measures (BAAQMD, May 2011) shall be instituted. The air quality construction plan shall be included on all grading, utility, building, landscaping, and improvement plans during all phases of construction, access roads, parking areas, and staging areas at construction sites. 39. Pre-construction Breeding Bird Surveys: Prior to development of the subject site and each phase of project activities that have the potential to result in impacts on breeding birds, the project applicant/developer shall take the following steps to avoid direct losses of nests, eggs, and nestlings and indirect impacts to avian breeding success: a) If grading or construction activities occur only during the nonbreeding season, between August 31 and February 1, no surveys shall be required. b) Pruning and removal of trees and other vegetation, including grading of grasslands, should occur whenever feasible, outside the breeding season (February 1 through August 31). c) During the breeding bird season (February 1 through August 31) a qualified biologist shall survey activity sites for nesting raptors and passerine birds not more than 14 days prior to any ground-disturbing activity or vegetation removal. Surveys shall include all line-of-sight trees within 500 feet (for raptors) and all vegetation (including bare ground) within 250 feet for all other species. d) Based on the results of the surveys, avoidance procedures shall be adopted, if necessary, on a case-by-case basis. These may include construction buffer areas (up to several hundred feet in the case of raptors) or seasonal avoidance. e) Bird nests initiated during construction are presumed to be unaffected, and no buffer is necessary except to avoid direct destruction of a nest or mortality of nestlings. f) If preconstruction surveys indicate that nests are inactive or potential habitat is unoccupied during the construction period, no further mitigation is required. Trees and shrubs that have been determined to be unoccupied by nesting or other special-status birds may be pruned or removed. 40. Pre-construction Bat Surveys: Prior to issuance of a building or grading permit, a qualified biologist shall conduct a pre-construction special status bat survey when large trees are to be removed or underutilized or vacant buildings are to be demolished. If active day or night roosts are found, the bat biologist shall take actions to make such roosts unsuitable habitat prior to tree removal or building demolition. A no-disturbance buffer of 100 feet shall be created around active bat 6 of 31
