City of Pleasanton—Merritt Property Project <br />15183 Consistency Checklist Consistency Checklist <br /> <br /> <br /> 79 <br />Plan shall include: (1) an assessment of all project impacts to <br />special-status bats, including noise disturbance during <br />construction; (2) effective AMMs to protect special-status bats; <br />(3) and compensatory mitigation for permanent impacts to <br />special-status bats or their nesting/roosting habitat. If structures, <br />trees, or other refugia equivalents are slated for limbing, removal, <br />or modification, the Bat Mitigation and Monitoring Plan shall <br />include the following measures: <br />• To ensure that special-status bats have left potential roosting <br />refugia, work shall occur over the course of 2 days. On the first <br />day, smaller limbs or items from the identified trees or structures <br />shall be brushed back or modified in the late afternoon. This <br />disturbance should cause any potential roosting bats to seek <br />other roosts during their nighttime foraging. The remainder of <br />the refugia item can then be further limbed or removed as <br />needed on the second day as late in the afternoon as <br />feasible. If bats are found injured, or if bat mortality occurs <br />during the course of tree work, a qualified Biologist shall record <br />the species impacted, and the number of individuals <br />documented. <br />• Tree limbing, modification, removal, or work on structural <br />refugia shall not be performed under any of the following <br />conditions: during any precipitation events, when ambient <br />temperatures are below 4.5 degrees Celsius, when windspeeds <br />exceed 11 mph, and/or any other condition which may lead <br />to bats seeking refuge. <br />• If special-status bats are found utilizing a tree, structure, or <br />equivalent for roosting, the Bat Mitigation and Monitoring Plan <br />shall include permanent artificial roosting habitat installations <br />that shall be adjacent to, and sufficient for, the species <br />observed and associated ecology thereof. Effective buffer <br />zones for the installation and monitoring of the artificial roosts <br />shall be determined and established by a qualified Biologist. <br /> <br />Erosion Control <br />Grading and excavation activities could expose soil to increased <br />rates of erosion during construction periods. During construction, <br />runoff from the project site could adversely affect aquatic life <br />within the adjacent water features. Surface water runoff could
