01/24/2011 Exhibit B particular water distribution system pipelines, other buried metal infrastructure and building materials, and concrete reinforcement, would be subject to damage and failure, and require high levels of maintenance or early replacement, due to the presence of extremely corrosive soils within the DPP area. a) Potential Impact. The impact identified above is described and discussed on pages 16 -7 to 16 -8 of the DEIR. b) Mitigation Measures. FEIR Mitigation Measure 16 -2 (p. 16 -8 of the DEIR) is hereby adopted and will be implemented as provided in the Mitigation Monitoring and Reporting Program. c) Findings. Based on the FEIR and the entire record before the City, the City Council finds that Mitigation Measure 16 -2 would reduce corrosive soil impacts to a less than significant level because it would: 1) require water systems and other buried metal infrastructure in all future development within the DPP to have protective coating conforming to the City's water system design criteria and specifications; and 2) require concrete mix designs to conform to state Depart of Transportation standards regarding corrosion. Impact 16 -3: Soil Erosion and Sedimentation. Grading for future development in accordance with the proposed DPP would temporarily disturb the site's existing topography and vegetative cover, leaving soils exposed to wind and water erosion during the construction period. Eroded soils could be washed into on- site or off -site drainage facilities. Resulting sedimentation could affect the flows in these drainage facilities, increasing flooding potential and maintenance problems and degrading water quality. a) Potential Impact. The impact identified above is described and discussed on page to 16 -8 of the DEIR. b) Mitigation Measures. FEIR Mitigation Measure 16 -3 (p. 16 -8 of the DEIR) is hereby adopted and will be implemented as provided in the Mitigation Monitoring and Reporting Program. c) Findings. Based on the FEIR and the entire record before the City, the City Council finds that Mitigation Measure 16- would reduce soil erosion and sedimentation impacts to a less than significant level because it would require applicants for future development projects in the DPP area involving a grading area of 10,000 or more square feet to prepare erosion control plans subject to City approval and consistent with the required project Stormwater Pollution Prevention Plans (SWPPPs) as well as Best Management Practices (BMPs) specified by the Redwood City Stormwater Management and Discharge Control Program (Municipal Code Chapter 27A) to implemented during construction.
