• Based on the results of the surveys, avoidance procedures will 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. • Bird nests initiated during construction are presumed to be unaffected by project activities, and no buffer would be necessary except to avoid direct destruction of a nest or mortality of nestlings. • If pre-construction surveys indicate that nests are inactive or potential habitat is unoccupied during the construction period,no further mitigation is required if work is initiated within 14 days of the survey. Trees and shrubs' that have been determined to be unoccupied by nesting or other special- status birds may be pruned or removed within 14 days of the pre- construction survey. Should activities be delayed beyond 14 days, pre- construction surveys shall be repeated prior to the start of work. Site(s) affected: All (Phase 1 and Full Buildout). Mitigation Measure 4.E-1: Pre-Construction Bat Surveys. Conditions of approval for building and grading permits issued for demolition and construction on sites within the EDZ area shall include a requirement for pre-construction special- status bat surveys when large trees constituting suitable habitat for roosting bats (e.g. trees with cavities or trees with bark that could be used for roosting such as eucalyptus and redwood) are to be removed or underutilized or vacant buildings are to be demolished. • Surveys shall be conducted by a qualified biologist prior to any tree removal or building demolition. Removal of trees and structures shall occur when bats are active, approximately between the periods of March 1 to April 15 and August 15 to October I 5; outside of bat maternity roosting season(approximately April 15 -August 31) and outside of months of winter torpor(approximately October 15 - February 28),to the extent feasible. • If removal of trees and structures during the periods when bats are active is not feasible and active bat roosts being used for maternity or hibernation purposes are found on or in the immediate vicinity of the site where tree and structure removal is planned, a no disturbance buffer of 100 feet shall be established around these roost sites until they are determined to be no longer active by the qualified biologist. A 100-foot no disturbance buffer is a typical protective buffer distance; however, buffer width may be modified by the qualified biologist depending on existing screening around the roost site(such as dense vegetation or a building) as well as the type of construction activity which would occur around the roost site. • The qualified biologist shall be present during tree and structure removal if potential bat roosting habitat or active bat roosts are present.
