buffer zone shall be established by a qualified biologist to protect the nesting site. This buffer shall be a minimum of 75 feet from the project activities for passerine birds, and a minimum of 200 feet for raptors. The distance shall be determined by a qualified biologist based on the site conditions (topography, if the nest is in a line of sight of the construction and the sensitivity of the birds nesting). The nest site(s) shall be monitored by a qualified biologist periodically to see if the birds are stressed by the construction activities and if the protective buffer needs to be increased. Once the young have fledged and are flying well enough to avoid project construction zones (typically by August), the project can proceed without further regard to the nest site(s). (Project Specific Condition) 10. PRE-CONSTRUCTION BURROWING OWL SURVEYS: No more than 30 days prior to any ground disturbing activities, a qualified biologist shall conduct a preconstruction/take avoidance survey for burrowing owls using methods described in Appendix D of the California Department of Fish and Wildlife (CDFW) Staff Report on Burrowing Owl Mitigation (Staff Report) (CDFW 2012). If no owls are detected during the initial take avoidance survey, a final survey shall be conducted within 24 hours prior to ground disturbance to confirm that owls are still absent. If present and no nesting has begun, nest exclusion doors or avoidance buffers may be used as negotiated with CDFW. No disturbance should occur within 50 meters (approximately 160 feet) of occupied burrows during the nonbreeding season of September 1 through January 31 or within 75 meters (approximately 250 feet) during the breeding season of February 1 through August 31. Avoidance also requires that a minimum of 6.5 acres of foraging habitat be preserved contiguous with occupied burrow sites for each pair of breeding burrowing owls (with or without dependent young) or single unpaired resident bird. It is recommended that an initial burrowing owl survey be performed during December and early January. If owls are discovered, passive relocation of the owls can take place. If owls are discovered after February 1, the owls must be left on site and a 250-foot buffer established until September 1. (Project Specific Condition) 11. PRE-CONSTRUCTION BAT SURVEY: The following measures shall be implemented in order to avoid "take" of special-status bats prior to the removal of any existing trees or structures on the project site: a) A bat habitat assessment shall be conducted by a qualified bat biologist during seasonal periods of bat activity (i.e., February 15 - April 15 and August 15 — October 30) to determine suitability of each existing trees as bat roost habitat. b) Structures found to have no suitable openings, therefore considered to contain no bats, can be considered clear for project activities as long as they are maintained so that new openings do not occur. c) Structures found to provide suitable roosting habitat, but without evidence of use by bats, may be sealed until project activities occur, as recommended by the bat biologist. Structures with openings and exhibiting evidence of use by bats shall be scheduled for humane bat exclusion and eviction, conducted during appropriate seasons, and under supervision of a qualified bat biologist. d) Bat exclusion and eviction shall only occur between February 15 and April 15, and from August 15 through October 30, in order to avoid take of non-volant (non—flying or inactive, either young, or seasonally torpid) individuals.
