<br />Project construction and operation will need to address potential impacts to local water <br /> <br />resources, increases in storm water runoff, needs for erosion control, and potential impacts to <br /> <br />surface and groundwater quality. EIP will consider the following elements in developing site- <br /> <br />specific mitigation measures: <br /> <br />. Contain stormwater on-site to reduce flood hazards or drainage problems and to maintain <br />existing water quality within local surface waters; <br /> <br />· Prevent increases in off-site flood hazards; <br /> <br />· Prevent on-site damage from soil erosion; <br /> <br />. Prevent increases in off-site sediment transport that could cause storm drain blockage or <br />channel aggradation; and <br /> <br />. Eliminate hazards caused by local flooding through expansIon and improved <br />management of the site drainage infrastructure. <br /> <br />EIP's assessment of the existing local and regional hydrologic conditions will focus on site <br />drainage, flood hazards, water quality, and groundwater contamination (if any) issues. The <br />analysis will consider existing drainage patterns, alternative project area drainage designs, the <br />potential for on-site erosion, and impacts on the local storm drain system. The overall analysis <br />will address San Leandro requirements and recommendations of the Regional Water Quality <br />Control Board (RWQCB), and will evaluate the impact of the proposed project on local and <br />regional hydrologic resources. The development of mitigation measures, which would include <br />recommendations for the preparation of a Storm Water Pollution Prevention Plan (SWPPP) <br />and/or an erosion control plan, an area drainage plan, and additional construction specifications, <br />will encourage storage and infiltration of runoff to keep peak flows at the property line at pre- <br />development levels. <br /> <br />Task 4.6 Soils, Geology, and Seismicity. The proposed Kaiser project is driven to a large <br />extent by Senate Bill 1953, to improve the seismic safety of hospital structures. The project <br />would be designed to meet current seismic standards. Therefore, seismic concerns would are not <br />anticipated to be an impact of the project. <br /> <br />With respect to soil conditions that may pose impacts for construction and long-term foundation <br />stability and integrity (e.g., expansive soils or soils subject to settlement), the City complies with <br />the California Building Code which requires the preparation of geotechnical reports by certified <br />professionals. Accordingly, it is not expected that soil conditions would lead to potentially <br />significant impacts. The Geotech Report prepared by Kaiser will be peer reviewed by EIP staff <br />member George Burwasser, Professional Geologist, as part of this task. <br /> <br />Given the above, the EIR section on soils, geology, and seismicity will document the existing <br />regulatory framework and how the standards and investigations required by these regulations <br />serve to mitigate potential impacts. <br /> <br />Task 4.7 Hazardous Materials. Data regarding existing use, handling, storage, and disposal of <br />hazardous materials and the subsequent generation of hazardous waste, including radioactive <br /> <br />Consulting Services Agreement between <br />City of San Leandro and EIP Associates <br /> <br />Page 32 of 44 <br />
