7.B. - Page 118 <br /> Mitigation Monitoring and Reporting Plan <br /> cofferdam design should be performed by a registered civil engineer and submitted to <br /> the City for review prior to construction. <br /> • The site is considered potentially corrosive to reinforcing steel embedded in concrete <br /> structures. A corrosion engineer should be consulted to adjust the concrete mix <br /> accordingly. <br /> Responsible Party: City of Redwood City oversight <br /> GREENHOUSE GAS EMISSIONS <br /> Mitigation Measure GHG 1: Best Management Practices (BMPs) for Reducing GHG <br /> Emissions from Construction <br /> The City shall encourage the Contractor to implement the following BMPs during construction of <br /> the proposed project,where appropriate: <br /> • At least 15 percent of the construction vehicle fleet shall use alternative fuel. <br /> • At least 10 percent of the materials used for project construction shall be sourced locally <br /> (within 50 miles of the project site). <br /> • At least 50 percent of the waste generated by project construction shall be recycled or <br /> reused. <br /> • Use low sulfur fuel for stationary construction equipment, to the extent feasible. <br /> • Use existing power sources (e.g.,power poles) or clean fuel generators rather than <br /> temporary power generators, to the extent feasible. <br /> • Use low emission on-site stationary equipment,to the extent feasible. <br /> Responsible Party: City of Redwood City oversight <br /> HYDROLOGY AND WATER QUALITY <br /> Mitigation Measure HYD 1: Implementation of BMPs <br /> The Contractor shall prepare a Storm Water Pollution Prevention Plan (SWPPP) and implement the <br /> BMPs contained in the SWPPP and the NPDES Permit Compliance Checklist (see Appendix I) to <br /> control and prevent the potential discharge of non-stormwater discharges and pollutants to <br /> Redwood Creek during construction. The Contractor shall utilize measures such as sediment <br /> barriers, silt fences, straw wattles,biodegradable fiber rolls, or hydraulic mulches to trap sediment in <br /> stormwater runoff during construction to prevent the discharge of pollutants to Redwood Creek. <br /> The Contractor shall revegetate the disturbed areas of landscaped vegetation along the creek banks <br /> with a hydroseed native plant mix for slope stabilization. The Contractor shall implement rock <br /> slope protection (RSP) on the creek bank below the proposed 18-inch drainage pipes' discharge <br /> points to prevent erosion along the creek bank. <br /> July 15,2013 A-7 US 101 Pedestrian Undercrossing and <br /> Bair Island Storm Water Pump Station Project <br />
