BI0-2b: For any dewatering that could occur during the construction period, all discharge water shall be pumped into a temporary siltation pond/desilting basin, Baker tank, or similar detention device for settling of sediments prior to their release downstream in accordance with the approved Stormwater Pollution Prevention Plan. BI0-2c: Excavated material shall not be placed on aquatic vegetation, or allowed to fall or be transported into Redwood Creek. 113I0 -2d: Silt -trapping devices shall be used to minimize downstream sedimentation. BI0-2e: Rock riprap in low -flow channels shall only be used where riprap is determined to be the only feasible stabilization approach. Individual bank stabilization activities using rock riprap shall not exceed 500 feet in length along the bank, and the amount of riprap used shall not exceed 1 cubic yard per running foot placed along the bank below the ordinary high water mark without specific authorization from the applicable resource agency. Finding: Implementation of Mitigation Measures BIO -2a through BI0-2e would reduce the project -related impact to longfin smelt and other native fish species to a less - than -significant level. Facts in Support of Findina: These mitigation measures appropriately identify the season in which longfin smelt or other native fish species are likely to be present, and address a process to avoid potential impacts if it is necessary to work below the ordinary high water mark or mean high tide line within Redwood Creek between December 1 and July 31. Impact BI0-3: Construction activities associated with the proposed project and the project variant could interfere with the movement or habitat quality of white-tailed kite and longfin smelt. Mitiaations 13I0 -3a: Prior to the initiation of construction activities (including demolition, and staging) all personnel associated with project construction shall attend an Environmental Awareness Training. The training should be conducted by a qualified biologist, to aid workers in recognizing special -status resources that may occur in the project area. The specifics of this program should include identification of the special -status species and habitats, a description of the regulatory status, and review of the measures required to reduce impacts to biological resources on the project site. Each worker shall be given a handout with key points. At the end of the training, all workers should sign to document their participation in the program and understanding of the measures. BI0-3b: No pets or firearms shall be allowed at the project site, with the exception of authorized law enforcement personnel. 13I0 -3c: All food -related trash that may attract predators and vermin shall be properly contained and removed from the work site daily. BI0-3d: All refueling, maintenance, and staging of equipment and vehicles shall occur at least 100 feet from the top of bank of Redwood Creek. Secondary containment shall be used during refueling. A spill prevention plan shall be in place prior to the initiation of demolition or construction activities. ATTY/RE50.0035/CC RESO CERTIFYING FINAL EIR-1548 MAPLE RESO.
