MiG 7.A. - Page 201 City of Redwood City EIR Addendum October 8,2012 Page 3-38 of intertidal wetland along Redwood Creek and Smith Slough sufficient to support incidental foraging by the California clapper rail, a federal- and state-listed endangered species. Similar to the mitigation for Impact 8-1, the associated 2003 EIR mitigation required coordination with the United States Fish and Wildlife Service (USFWS) and CDFG on clapper rail issues and associated implementation of an HMMP subject to approval by these agencies. The current Pete's Harbor project would not fill any existing intertidal wetland. However, the project would include construction adjacent to the intertidal wetland along Redwood Creek and Smith Slough to accommodate public access and landscaping (see Figure 3.5-1 and figures in chapter 2 of this Addendum). The potential for impacts of construction directly adjacent to intertidal wetland (e.g., noise, contaminant release) would remain. Conclusion. Modified impact. The impact has been modified to remove the reference to "direct long-term loss of intertidal wetland" because this particular situation would not occur under the current Pete's Harbor project. The mitigation identified in the 2003 EIR for Impact 8-3 remains applicable to the current Pete's Harbor project and remains sufficient to reduce the impact to a less-than-significant level. As stated in the mitigation, if the required breeding surveys (subject to USFWS and CDFG approval) conclude to jurisdictional agency satisfaction that the distance of any identified clapper rail territory from project construction activity represents a suitable buffer, no further action regarding the clapper rail would be required. Impact 8-4 Analysis: General Construction Noise Impacts on Wildlife. The certified 2003 EIR indicated that existing foraging and reproductive activities of wildlife in the adjacent sensitive habitat areas (e.g., Bair Island Wildlife Refuge), including habitat of special-status species, could be disrupted by project construction activity and noise. Affected special-status species could include: California clapper rail, California least tern, Western snowy plover, California black rail, northern harrier, short-eared owl, saltmarsh common yellowthroat, and Alameda song sparrow. The associated 2003 EIR mitigation described mitigation similar to that for Impact 8-1, including coordination with the USFWS and CDFG on the issue, completion of jurisdictional agency- required special-status species surveys, and implementation of an associated USFWS- and CDFG-approved HMMP. Pete's Harbor project construction activities could disrupt Redwood Creek and Smith Slough estuarine habitat and other adjacent sensitive habitat areas (e.g., Bair Island Wildlife Refuge) for one or more of these species. Conclusion. No change. The mitigation identified in the 2003 EIR for Impact 8-4 remains applicable to the current Pete's Harbor project and remains sufficient to reduce this impact to a less-than-significant level. As stated in the mitigation, if the required breeding surveys (subject to USFWS and CDFG approval) conclude to jurisdictional agency satisfaction that the distance of any identified special-status species territory from project construction activity represents a suitable buffer, no further action regarding the identified species would be required. Impact 8-5 Analysis: Project-Related Loss of Estuarine Navigable Waters and Other Waters of the U.S. The certified 2003 EIR indicated that the project would fill approximately 11.54 acres of waters under the jurisdiction of the Army Corps of Engineers (Corps) (also see Impact 8-1). The associated 2003 EIR mitigation described a series of related jurisdictional T.•1106951Addenduml3(10695-01).doc
