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 that <br /> a minimum of 6 5 acres of foraging habitat be preserved contiguous with occupied burrow <br /> sites for each pair of breeding burrowing owls (with or without dependent young) or single <br /> unpaired resident bird It is recommended that an initial burrowing owl survey be performed <br /> during December and early January If owls are discovered, passive relocation of the owls <br /> can take place If owls are discovered after February 1, the owls must be left on site and a <br /> 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 on <br /> 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 no <br /> bats, can be considered clear for project activities as long as they are maintained <br /> 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 be <br /> scheduled for humane bat exclusion and eviction, conducted during appropriate <br /> seasons, and under supervision of a qualified bat biologist <br /> d) Bat exclusion and eviction shall only occur between February 15 and April 15, and <br /> from August 15 through October 30, in order to avoid take of non-volant (non— <br /> flying or inactive, either young, or seasonally torpid) individuals <br /> Prior to issuance of a building or grading permit, a qualified wildlife biologist experienced in <br /> surveying for and identifying bat species shall survey the portion of the oak/bay woodland <br /> habitat if tree removal is proposed to determine if any special—status bats reside in the <br /> trees Any special—status bats identified shall be removed without harm Bat houses <br /> sufficient to shelter the number of bats removed shall be erected in open space areas that <br /> would not be disturbed by project development A written report prepared by a qualified <br /> Case No PUD-114, 11300 Dublin Canyon City Council <br /> Page 8 of 26 <br />
