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). 26. Pre - construction Bat Survey: The following mitigation measures shall be implemented in order to avoid "take" of special- status bats prior to the removal of any existing trees 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. 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. Or, prior to issuance of a building or grading permit, a qualified wildlife biologist experienced in surveying for and identifying bat species shall survey the portion of the oak /bay woodland habitat if tree removal is proposed to determine if any special— status bats reside in the trees. Any special— status bats identified shall be removed without harm. Bat houses sufficient to shelter the number of bats removed shall be erected in open space areas that would not be disturbed by project development. A written report prepared by a qualified biologist documenting survey results shall be submitted to the Director of Community Development for review and approval. 27. Pre - Construction Dusky- footed Woodrat Survey: Prior to commencing any construction - related activities, as determined by the biologist, that may result in the destruction of dusky- footed woodrat nests, surveys shall be conducted by a qualified biologist to determine the occurrence of the nests. If found, construction fencing shall be installed around the nest at a distance specified by the biologist to avoid impacts, and a wildlife biologist shall be present during a timeframe specified by the biologist upon the initiation of construction to monitor construction activities until such time that the biologist determines that it is not needed. 28. The wood fence on Lots 1 and 3 shall meet the recommendations as stated in the Noise Assessment Study prepared by Edward L. Pack Associates. The construction detail of the fence shall be included in the building permit plan check plans and is subject to the review and approval of the Director of Community Development prior to issuance of a building or grading permit.
