If vegetation removal, construction, or grading activities are planned to occur within the nesting bird season (February 1 to September 30), the City of Santa Ana (City) Public Works Director or designee shall ensure that a qualified biologist conducts a preconstruction nesting bird survey no more than three days prior to the start of such activities. The nesting bird survey shall include the Project site and areas immediately adjacent to the site that could potentially be affected by Project-related activities such as noise, vibration, increased human activity, and dust, etc. For any active nest(s) identified, the qualified biologist shall establish an appropriate buffer zone around the active nest(s). The appropriate buffer shall be determined by the qualified biologist based on the species, location, and nature of the proposed activities. Project activities shall be avoided within the buffer zone until the nest is deemed no longer active by the qualified biologist.
