City of Pleasanton—Hidden Canyon Residences and Preserve Draft EIR Executive Summary FirstCarbon Solutions ES-26 https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480016/EIR/3 - Draft EIR/21480016 Sec00-03 Exec Summary.docx Impacts Level of Significance Before Mitigation Mitigation Measures Level of Significance After Mitigation To avoid potential impacts to active burrowing owl nests and adult owls, a qualified Biologist shall conduct pre- construction surveys for burrowing owls within the construction footprint and within 250 feet of the footprint no more than 7 days prior to project ground disturbance during the early part of breeding season (i.e., February 1 through April 30), and no more than 30 days prior to onset of ground disturbance during any other times of year. These surveys shall be conducted in a manner consistent with accepted burrowing owl survey protocols. Specific Avoidance and Minimization Measures for the burrowing owl are reported in Table 3-3 of the East Alameda County Conservation Strategy (EACCS). These measures are mandatory for mitigation and include: • If an active nest is identified near a proposed work area work will be conducted outside of the nesting season (March 15 to September 1). • If an active nest is identified near a proposed work area and work cannot be conducted outside of the nesting season, a no-activity zone shall be established by a qualified Biologist. The no-activity zone shall be large enough to avoid nest abandonment and will at a minimum, be 250-feet radius from the nest. • If the burrowing owls are present at the project site during the nonbreeding period, a qualified Biologist shall establish a no-activity zone of at least 150 feet.
