Executive Summary <br /> Level of <br /> Potential Impacts Significance Mitigation Measures <br /> activities(e.g.,vegetation clearing or grading)and again within 24 hours prior to <br /> these activities.A qualified biologist shall conduct preconstruction surveys on the <br /> Project site and 150 meters around the Project site(access permitting)in areas with <br /> suitable burrowing habitat to locate any active breeding or wintering BUOW <br /> burrows.The survey methodology shall be consistent with the Take Avoidance <br /> Survey methods outlined in the CDFW(2012)Staff Report on Burrowing Owl <br /> Mitigation and shall consist of walking parallel transects 7 to 20 meters apart, noting <br /> any potential burrows with fresh BUOW sign or presence of BUOWs, and visiting <br /> potential burrows during the time of day described in the protocol. If the work activity <br /> halts for a period of 7 days or more,the survey would need to be conducted again <br /> prior to the continuation of site activities.Copies of the survey results shall be <br /> submitted to the CDFW. If BUOWs are found during the preconstruction surveys, <br /> the following measures shall be implemented. Buffer distances may be modified <br /> based on the judgement of a qualified biologist, in coordination with CDFW, <br /> USFWS, and SJCOG. <br /> 00 If BUOWs are detected on the Project site or within 150 meters during the <br /> breeding season(February 1 to August 31)or non-breeding(winter) <br /> season, no ground disturbing activities,such as vegetation clearance, <br /> grading, or equipment staging,shall be permitted within 75 meters of the <br /> occupied burrow until and unless the TAC,with the concurrence of the <br /> Permitting Agencies' representatives on the TAC, or unless a qualified <br /> biologist approved by the Permitting Agencies verifies through non- <br /> invasive means that either 1)the birds have not begun egg laying, or 2) <br /> juveniles from the occupied burrows are foraging independently and <br /> capable of independent survival.Once the fledglings are capable of <br /> independent survival,the burrow can be destroyed per Section 5.2.4.15 of <br /> the SJMSCP. <br /> 00 If avoidance of occupied burrows is infeasible during the non-breeding <br /> season(September 1 to January 31)or during the breeding season <br /> (February 1 to August 31)where resident BUOWs have not yet begun egg <br /> laying or incubation or where the juveniles are foraging independently and <br /> capable of independent survival,a qualified biologist shall implement a <br /> passive relocation program in accordance with the CDFW(2012)Staff <br /> Report on Burrowing Owl Mitigation. If passive relocation is anticipated <br /> due to on-site BUOW populations, a Burrowing Owl Exclusion Plan in <br /> accordance with CDFW Staff Report on Burrowing Owl Mitigation would <br /> be prepared by a qualified biologist prior to passive relocation activities. <br /> Swainson's Hawk <br /> This species is covered under the SJMSCP but is not a focal species in the EACCS <br /> (see Section 5.2.4.11).
