City reviews contractor bid documents City Prior to construction Contractor implements measures in the program. City documents that measures are being implemented City’s construction manager During construction Biological Resources Mitigation Measure BIO-1: Avoid and Minimize Impacts to Salt Marsh Wandering Shrew. The following mitigation measures are recommended to avoid potential impacts to salt marsh wandering shrew: • A CDFW-approved biologist shall conduct a preconstruction survey for the salt marsh wandering shrew at the appropriate time of day within the work area within 48 hours prior to the commencement of construction activities. The survey shall entail the biologist walking the work area limits to determine the possible presence of shrews. The biologist shall investigate all potential areas that may be utilized by this species for breeding, sheltering, movement, and other essential behaviors. • 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 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.
