7.A. - Page 206 Pete's Harbor <br /> Gity ot Hedwood Gity EIR Addendum <br /> October 8, 2012 Page 3-43 <br /> necessary to reconfigure the marinas would disturb marina bottom sediments and result in <br /> temporary water quality impacts. The associated 2003 EIR required several associated <br /> mitigation measures, subject to approval by the Corps, Dredged Materials Management Office <br /> (DMMO--a joint federal-state program), BCDC, and RWQCB. <br /> The current Pete's Harbor project would not include any dredging or marina fill operations. <br /> Conclusion. Mitigation 9-3 is no longer required. The currently proposed Pete's Harbor project <br /> would not include any dredging or marina fill operations, and this impact would not occur. <br /> Impact 9-4 Analysis: Project Impacts on Marina and Creek Sedimentation and <br /> Associated Creek/Bay Water Quality Impacts. The certified 2003 EIR indicated that the <br /> project-related reduction in marina area would reduce the tidal prism and result in increased <br /> rates of siltation, requiring more frequent dredging in the future, and resulting in more frequent <br /> water quality disturbances. The associated 2003 EIR mitigation included a requirement for <br /> additional hydraulic analyses to determine if the marinas would sufficiently self-scour, or <br /> whether there would be any potential future increased need to dredge Redwood Creek. <br /> The current Pete's Harbor project would not fill any marina area. <br /> Conclusion. Mitigation 9-4 is no longer required. The currently proposed Pete's Harbor project <br /> would not fill any marina area, and this impact would not occur. <br /> Other Impacts. The certified 2003 EIR determined that the previous Marina Shores Village <br /> project would have less-than-significant impacts on the site peak stormwater run-off flow rate, <br /> groundwater recharge, flooding, and long-term marina tidal water circulation rates and <br /> associated long-term water quality conditions. The current Pete's Harbor project includes no <br /> changes or new conditions that would adversely affect these conclusions. <br /> T.•1106951Addenduml3(10695-01).doc <br />
