survey for burrowing owls using methods described in Appendix D of the California <br /> Department of Fish and Wildlife (CDFW) Staff Report on Burrowing Owl Mitigation (Staff <br /> Report) (CDFW 2012). If no owls are detected during the initial take avoidance survey, a <br /> final survey shall be conducted within 24 hours prior to ground disturbance to confirm that <br /> owls are still absent. If present and no nesting has begun, nest exclusion doors or <br /> avoidance buffers may be used as negotiated with CDFW. No disturbance should occur <br /> within 50 meters (approximately 160 feet) of occupied burrows during the nonbreeding <br /> season of September 1 through January 31 or within 75 meters (approximately 250 feet) <br /> during the breeding season of February 1 through August 31. Avoidance also requires <br /> that a minimum of 6.5 acres of foraging habitat be preserved contiguous with occupied <br /> burrow sites for each pair of breeding burrowing owls (with or without dependent young) <br /> or single unpaired resident bird. It is recommended that an initial burrowing owl survey be <br /> performed during December and early January. If owls are discovered, passive relocation <br /> of the owls can take place. If owls are discovered after February 1, the owls must be left <br /> on site and a 250-foot buffer established until September 1. <br /> 35. Pre-construction Bat Survey: The following measures shall be implemented in order to <br /> avoid "take" of special-status bats prior to the removal of any existing trees or structures <br /> on the project site: <br /> a) A bat habitat assessment shall be conducted by a qualified bat biologist during <br /> seasonal periods of bat activity (i.e., February 15 - April 15 and August 15 — <br /> October 30) to determine suitability of each existing trees as bat roost habitat. <br /> b) Structures found to have no suitable openings, therefore considered to contain <br /> no bats, can be considered clear for project activities as long as they are <br /> maintained so that new openings do not occur. <br /> c) Structures found to provide suitable roosting habitat, but without evidence of use <br /> by bats, may be sealed until project activities occur, as recommended by the bat <br /> biologist. Structures with openings and exhibiting evidence of use by bats shall <br /> be scheduled for humane bat exclusion and eviction, conducted during <br /> appropriate seasons, and under supervision of a qualified bat biologist. <br /> d) Bat exclusion and eviction shall only occur between February 15 and April 15, <br /> and from August 15 through October 30, in order to avoid take of non-volant <br /> (non—flying or inactive, either young, or seasonally torpid) individuals. <br /> Prior to issuance of a building or grading permit, a qualified wildlife biologist experienced <br /> in surveying for and identifying bat species shall survey the portion of the oak/bay <br /> woodland habitat if tree removal is proposed to determine if any special—status bats <br /> reside in the trees. Any special—status bats identified shall be removed without harm. Bat <br /> houses sufficient to shelter the number of bats removed shall be erected in open space <br /> areas that would not be disturbed by project development.
