c. 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.
d. 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 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young have left the nest and are foraging independently or the nest is no longer
active.
e. 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.

any exclusion efforts to ensure individual bats have been successfully
evicted in advance of initiating tree removal or building demolition.
iii. If a maternity roost is detected, and young are found roosting in a building
identified for demolition, renovation, or re‐tenanting, work shall be
postponed until the young are flying free and are feeding on their own, as
determined by the qualified biologist.
iv. Once the qualified biologist has determined that any young bats can
successfully function without the maternity roost, then the adults and
young bats can be excluded from the structure to be demolished using the
one‐way eviction methods described above.
v. Monitoring shall be provided by the qualified biologist as necessary to
determine status of any roosting activity, success of any required bat
exclusion, and status of any maternity roosting activity by bats, in the
remote instance a maternity roost is encountered on the site.
E. Cultural Resources Permit Requirements
1. Protect Archaeological Resources and Tribal Cultural Resources: For all
