Docusign Envelope ID: 3D940908-FK64E95-8861-1 EA134A568D0 disturbance during construction; (2) effective avoidance and minimization measures to protect special -status bats; (3) and compensatory mitigation for permanent impacts to special -status bats or their nesting/roosting habitat. If structures, trees, or other refugia equivalents are slated for limbing, removal, or modification, the Bat Mitigation and Monitoring Plan shall include the following measures: To ensure that special -status bats have left potential roosting refugia, work shall occur over the course of two days. On the first day, smaller limbs or items from the identified trees or structures shall be brushed back or modified in the late afternoon. This disturbance should cause any potential roosting bats to seek other roosts during their nighttime foraging. The remainder of the refugia item can then be further limbed or removed as needed on the second day as late in the afternoon as feasible. If bats are found injured, or if bat mortality occurs during the course of tree work, a qualified biologist shall record the species impacted, and the number of individuals documented. • Tree limbing, modification, removal, or work on structural refugia shall not be performed under any of the following conditions: during any precipitation events, when ambient temperatures are below 4.5 degrees Celsius, when windspeeds exceed 11 miles per hour, and/or any other condition which may lead to bats seeking refuge. If special -status bats are found utilizing a tree, structure, or equivalent for roosting, the Bat Mitigation and Monitoring Plan shall include permanent artificial roosting habitat installations that shall be adjacent to, and sufficient for, the species observed and associated ecology thereof. Effective buffer zones for the installation and monitoring of the artificial roosts shall be determined and established by a qualified biologist. Erosion Control — Grading and excavation activities could expose soil to increased rates of erosion during construction periods. During construction, runoff from the Property could adversely affect aquatic life within the adjacent water features. Surface water runoff could remove particles of fill or excavated soil from the site, or could erode soil down -gradient, if the flow were not controlled. Deposition of eroded material in adjacent water features could increase turbidity, thereby endangering aquatic life, and reducing wildlife habitat. Implementation of appropriate mitigation measures would ensure that impacts to aquatic organisms would be avoided or minimized. Mitigation measures may include best management practices (BMP's) such as hay bales, silt fencing, placement of straw mulch and hydro seeding of exposed soils after construction as identified in the Storm Water Pollution Prevention Plan (SWPPP).
