Discharge of urban poEtutants(petroleum hydrocarbons and heavy metals associated with automobile use) from parkin�;areas at the site may he considered a significant impact. C;ompliance�vith existing stormwater quality regulations ��ould be outlined as the minimum requirement for project mitigation of potential stormwater qtia.lity im�acts. . Describe K�etlantl restoration acti��ities. It is passible that the wetland restoration activities proposecl by f1ZC project could result in hydrnlogic and/or temporary water quality impacts.The E:IEZ at;atys�s and diSCliSSiGi1 Wil� C��y(3I'1 COTYI��I�FlC�W3i�1 8j7(�i1C3UIe 1'eS011TCE 3�TCriCy requirements ta mitigate thesc potcntial impacts. Practical miti�ation measures that would reduce or eliminaie ary identified potential impacts related to hydrology; storm drainage, and wa.ter c�uality woi�l�1 be identified.Additiona?mitiga±ion may focus on incorporating source control(designed to eliminate exposure of runoff to pollutants)and treatment controt (designed to treat runoff that may contain pol.iutants)BMPs in the project design to minimize impacts to water quality, and manitoring and maintenance provisions for the proposed levee improvements. 5. Hazards and Hazardous Materials a. Issues.The project includes new residences and a new 450-student public eIementary schoot. School sites are subject to an increased level of scrutiny due to the sensitive nature of their use by children and the potential for even low levels of exposure to pollutants to have long term effects. Baseiine understands that a Phase I Environmental Assessment,an Air Flight Risk Study and a Geohazards Study have been prepared and wi11 be available for review.In addition,Base3ine will aiso analyze other potential hazards, such as highway proximity,power line proximity,and gas lines locations. b. A�proach.Baseline wt�uld prepare fhe Nazards stitbsection of the EIR,which�v��a1.d eval��ate potentia]threats to public health and safety from hazardous materials and other hazards that could result from development of the proposed project. Practical mitigation measures would be drafted to mitigate identified significant impacts, where appropriate. To describe the existing conditions at the project site,Baseline would perform the following tasks: • Review available environmental investigation reports. Review availabie environmental investigation reports for the project site and immediate vicinity. Based on this information, Baseline would describe known and potential harardous tnaterials issues at and near the project Sit�. • Describe the existi�zg regulatory firameworl� Desci-ibe the existing regulatory framework for public health and hazardous materials,highlighting those re�;ulations and programs that may apply to development of the project. • Describe emerger:cy response and evacuation plans. Describe emergency response and evacuation plans in the project vicinity, as well as summarize existing prograrns and requirements for eniergency response.
