3. Environmental Checklist ■ Prior to vegetation removal, upland portions of the site shall be mowed for the purpose of removing cover and encouraging salt marsh wandering shrew to seek cover in the areas outside of the construction area. After vegetation is removed, silt exclusion fencing with wire -mesh backing shall be installed by hand along all tidal channels to prevent salt marsh wandering shrew from entering the active work area, to protect adjacent habitat from construction activities or accidental spills, and to exclude workers from adjacent habitat. If a salt marsh wandering shrew is observed in or near the Project area, all construction shall cease until the salt marsh wandering shrew is captured by a CDFW-approved biologist possessing the appropriate permits and relocated to other suitable habitat on the Project site in accordance with a pre -approved Sensitive Species Relocation Plan (SSRP). A brief SSRP shall be submitted to and approved by the CDFW and USFWS prior to the re -initiation of any Project activities. The area beneath vehicles or equipment parked in the Project area shall be checked for the presence of salt marsh wandering shrew before being moved, during construction, and during movement of staging materials within the entire Project site. ■ Vehicle speed limits on the Project site shall not exceed 10 miles per hour. Mitigation Measure BIO-2: Avoid and Minimize Impacts to Roosting Bats. A qualified biologist shall conduct a pre -construction survey for roosting bats in all suitable bat roosting habitat (large trees, concrete vault box) within the Project area within 14 days prior to the beginning of Project -related activities. If active bat roosts are discovered or if evidence of recent prior occupation is established, a buffer shall be established around the roost site until the roost site is no longer active. If an active bat roost needs to be removed as part of the Proposed Project, the Project biologist would need to consult CDFW to determine appropriate methods for the removal of the roost. As part of CDFW's approval, a new roost site may need to be created on the Project site as mitigation. Mitigation Measure BIO-3: Avoid and Minimize Impacts to Nesting Birds. Project staging, Project construction, vegetation removal, or tree trimming should be performed outside of the bird nesting season (February 1st through August 31st) to avoid impacts to nesting birds; if these activities must be performed during the nesting bird season, a qualified biologist shall be retained to conduct a pre- construction survey in the Project construction and staging areas for nesting birds and verify the presence or absence of nesting birds no more than 14 days prior to construction activities or after any construction breaks of 14 days or more. Surveys shall be performed for the Project construction and staging areas and suitable habitat within 500 feet of the Project construction and staging areas, where accessible, to locate the presence of nesting birds and raptors. If nesting birds and raptors do not occur within 250 and 500 feet of the Project site, respectively, then no further action is required if construction begins within two weeks. If active nests are located during the pre -construction bird nesting surveys, no -disturbance buffer zones shall be established around nests, with a buffer size established by the qualified biologist. If the survey indicates the presence of active nests, no -disturbance buffer zones shall be established around the nests by the qualified biologist, as follows: San Leandro Treatment Wetlana IS/MND
