entrance is observed within the last three years. If a burrowing owl or sign is present <br />on the Property three additional protocol level surveys will be initiated. Once these <br />surveys have been completed to identify the owl’s location, disturbance buffers should <br />be placed around each active burrow. No disturbance should occur within 250 feet of <br />occupied burrows during the breeding season (February 1 through August 31) and/or <br />within 160 feet of occupied burrows during non-breeding season (September 1 <br />through January 31). Pre-construction surveys shall be completed 14 days prior to <br />initiating activities. <br /> <br />• Special-status Bats Surveys – For all Project activities planned in or adjacent to <br />potential bat roosting habitat, such as structures and/or involving woody vegetation <br />modification or removal of any and all trees, a qualified biologist shall conduct daytime <br />and evening acoustic surveys in addition to extensive visual surveys of potential <br />habitat for special-status bats at least 7 days prior to initiation of Project activities. If <br />bats are found on-site, a qualified biologist shall identify the species, estimated <br />quantity present, roost type, and roost status, but shall avoid disturbing bats during <br />surveys. A qualified biologist shall also create a Bat Mitigation and Monitoring Plan if <br />special-status bat species are detected prior to the start of Project activities. The Bat <br />Mitigation and Monitoring Plan shall include: (1) an assessment of all Project impacts <br />to special-status bats, including noise disturbance during construction; (2) effective <br />avoidance and minimization measures to protect special-status bats; (3) and <br />compensatory mitigation for permanent impacts to special-status bats or their <br />nesting/roosting habitat. If structures, trees, or other refugia equivalents are slated for <br />limbing, removal, or modification, the Bat Mitigation and Monitoring Plan shall include <br />the following measures: <br /> <br />• To ensure that special-status bats have left potential roosting refugia, work shall occur <br />over the course of two days. On the first day, smaller limbs or items from the identified <br />trees or structures shall be brushed back or modified in the late afternoon. This <br />disturbance should cause any potential roosting bats to seek other roosts during their <br />nighttime foraging. The remainder of the refugia item can then be further limbed or <br />removed as needed on the second day as late in the afternoon as feasible. If bats are <br />found injured, or if bat mortality occurs during the course of tree work, a qualified <br />biologist shall record the species impacted, and the number of individuals <br />documented. <br /> <br />• Tree limbing, modification, removal, or work on structural refugia shall not be <br />performed under any of the following conditions: during any precipitation events, <br />when ambient temperatures are below 4.5 degrees Celsius, when windspeeds <br />exceed 11 miles per hour, and/or any other condition which may lead to bats seeking <br />refuge. <br /> <br />• If special-status bats are found utilizing a tree, structure, or equivalent for roosting, the <br />Bat Mitigation and Monitoring Plan shall include permanent artificial roosting habitat <br />installations that shall be adjacent to, and sufficient for, the species observed and <br />associated ecology thereof. Effective buffer zones for the installation and monitoring <br />of the artificial roosts shall be determined and established by a qualified biologist. <br /> <br />• Erosion Control – Grading and excavation activities could expose soil to increased <br />rates of erosion during construction periods. During construction, runoff from the <br />Property could adversely affect aquatic life within the adjacent water features. Surface <br />water runoff could remove particles of fill or excavated soil from the site, or could
