I_)escribe existing local policies from the Safety Element of the Redwood City General Plan tlzat acldress hazardous materials and other public health and safety concerns. I'otential impacts would be evaluated for future construction worl<ers, future users a.nd maintenance workers, and other workers, residents,and students in the project vicinity. This analysis would include an evaluation of the potential for contaminants to be present in soil and groundwater at the project site which could be released during construction activities, as well as the potential health effects fro�n residual contamination at the project site following constraction. Practical miti�ation m.easures w�uld be drafted, if warranted,to address any identified si�,7nificant impacts. Mitigation wauld likely include recommendations of environmental investigations compleied for the for the site, coiiection anci anaiysis of samples irom ihe site tor the contaminants described abave,implementation of construction worker health and safety and rislc management plans (for protection of warkers and the surrounding community),implenlentation of best management practices for hazardous materials storage during construction to rnin.imize the potential for releases fo occur,and compliance with Iocal, state, and Federal hazardous rnaterials reguIations during construction. 6. Biologicai Resources a. Issues.The project site has been disturbed and altered by the construction of levees and grading but is tocated in an area of resource concern because of its proximity to the Don Edwards San Francisco Bay National Wildlife Refuge and to habitat for two endangered species: the California clapper rail and the salt marsh harvest mouse.The Huffrnan-Broadway Group,Ine. has conducted biolagical evaluation of the site for the applicant and conciuded that there are no endangered species present on the site and that it is unlikely ta provide habitat for any endangered species. They have also completed the wetland delineation for the site which has been verified by the Army Corps of Engineers. The applicant estimates that the project will adversely affect less than S acres of wetlands and proposes wetlands restoration of 94 acres out of the 114.5 acre site. b. Approach.LSA propvses to use the work done by Huffrnan-Broadway Group, Inc., other technica]reports, and consultation with resource and regulatory agencies to prepare the Biological R�so�arces subsection of the EIR. No additional field or sun�ey work is proposed at this�ime. LSA does have experienced biologists and wetlands specialists on staff who can provide expertise and assistance should issues regarding biological resources require more investigation than initially scoped. In preparation of the Biological Resources subsection of the EIR,the foliowing tasks would he campleted: • Prepare binlogical resources setting section. Existing bialogical resources within the project area will be descriUed,based on a review of previaus reports, surveys,and avaiiable technical studies, and discussions with the resource and regulatory agencies,and other experts.This discussion will also include existing habitat types,potential and existing special-status plant and wild3ife species, speciat-status habitats, wetlands, f sh and wildiife values,and�nigratoiy corridors. • Impacts. LSA will evaluate potential impacts to biological resources and jurisdictional waters resulting from the proposed project.
