AVOID NESTING BIRDS DURING CONSTRUCTION Prior to issuance of the any demolition, grading and building permit, indicate the following on all construction plans: 883 September Drive Page 4 of 8 RM-2022-004 Demolition, construction, ground-disturbing, and tree removal/pruning activities shall be scheduled to be completed prior to nesting season (February 1 through August 31),if feasible. If demolition, construction, ground-disturbing, or tree removal/pruning activities occur during the nesting season(February 1 and August 31), preconstruction surveys shall be conducted as follows: No more than 7 days prior to the start of demolition,construction,ground-disturbing, or tree removal/pruning activities, in order to identify any active nests with eggs or young birds on the site and surrounding area within 100 feet of construction or tree removal activities. Preconstruction surveys shall be repeated at 14-day intervals until demolition, construction, ground-disturbing, or tree removal/pruning activities have been initiated in the area,after which surveys can be stopped.As part of the preconstruction survey(s), the surveyor shall inspect all trees and other possible nesting habitats in, and immediately adjacent to, the construction areas for active nests, while ensuring that they do not disturb the nests as follows: For projects that require the demolition or construction one single-family residence, ground disturbing activities affecting areas of up to 500 square feet, or the removal of up to three trees, the property owner or a tree removal contractor, if necessary, is permitted to conduct the preconstruction surveys to identify if there are any active nests. If any active nests with eggs or young birds are identified, the project applicant shall retain a qualified ornithologist or biologist to identify protective measures. For any other demolition, construction and ground disturbing activity or the removal of four or more trees, a qualified ornithologist or biologist shall be retained by the project applicant to conduct the preconstruction surveys. If the preconstruction survey does not identify any active nests with eggs or young birds that would be affected by demolition, construction, ground-disturbing or tree removal/pruning activities, no further mitigating action is required. If an active nest containing eggs or young birds is found sufficiently close to work areas to be disturbed by these activities,their locations shall be documented,and the qualified ornithologist or biologist shall identify protective measures to be implemented under their direction until the nests no longer contain eggs or young birds. Protective measures may include, but are not limited to, establishment of clearly delineated exclusion zones (i.e., demarcated by identifiable fencing, such as orange construction fencing or equivalent) around each nest location as determined by the qualified ornithologist or biologist, taking into account the species of birds nesting, their tolerance for disturbance and proximity to existing development. In general, exclusion zones shall be a minimum of 300 feet for raptors and 75 feet for passerines and other birds. The active nest within an exclusion zone shall be monitored on a weekly basis throughout the nesting season to identify signs of disturbance and 883 September Drive Page 5 of 8 RM-2022-004 confirm nesting status. The radius of an exclusion zone may be increased by the qualified ornithologist or biologist,if project activities are determined to be adversely affecting the nesting birds. Exclusion zones may be reduced by the qualified ornithologist or biologist only in consultation with California Department of Fish and Wildlife. The protection measures and buffers shall remain in effect until the young have left the nest and are foraging independently or the nest is no longer active. A final report on nesting birds and raptors, including survey methodology, survey date(s), map of identified active nests (if any), and protection measures (if required), shall be prepared by the qualified ornithologist or biologist and submitted to the Director of Community Development or his or her designee, through the appropriate permit review process (e.g., demolition, construction, tree removal, etc.), and be completed to the satisfaction of the Community Development Director prior to the start of demolition, construction, ground-disturbing, or tree removal/pruning activities. 13.
