7.A. - Page 25 e. The proposed amendments and project will not cause a potentially significant impact to arry known cemeteries or human remains in the project area (EIR p. 7-7). However, should arry human remains be found during on- or off- site improvements associated with the proposed project, the City of Redwood City Cultural Resources Management Plan guidelines and EIR Mitigation 7-1 require that construction activities be halted immediately and the County coroner and a professional archaeologist be consulted to evaluate the significance of the find. If the remains are Native American, the Native American Heritage Commission is required to be notified. These measures, which shall be required as conditions of approval for the project, will reduce the potential impacts of the project on human remains to a less-than-significant level.

GEOLOGY AND SOILS — Would the project: a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: The project would not create new geologic hazards that could damage project or nearby facilities. Therefore, this section focuses on the effect of local geologic conditions and activity on the proposed project. i) Rupture of a known earthquake fault, as delineated on the most recent X Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault (Division of Mines and Geology Special Publication 42)? ii) Strong seismic ground shaking? X iii) Seismic-related ground failure, including liquefaction? X iv) Landslides? X b) Result in substantial soil erosion or the loss of topsoil? X c) Be located on a geologic unit or soil that is unstable, or that would become X unstable as a result of the proj ect, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction, or collapse? d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform X Building Code, creating substantial risks to life or property? e) Have soils incapable of adequately supporting the use of septic tanks or X alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? Documentation a. i) The Downtown Precise Plan area is located within the seismically active San Francisco Bay Area. The significant earthquakes that occur in the Bay Area are generally associated with crustal movement along well- defined, active fault zones of the San Andreas Fault system, which trends in a northwesterly direction. The proposed amendments and the project site are located approximately five miles northeast of the San Andreas Fault. Two other major active faults in the area are the Hayward Fault, located about 14 miles northeast of the project site, and the San Gregorio-Seal Cove Fault, located about 13 miles to the west. (DTPP EIR p. 16-1) The plan area and the project site are not within an Alquist-Priolo Earthquake Fault Zone (DTPP EIR p. 16-1); therefore, there is no known potential for fault rupture. ii) The plan area and project site lies in a seismically active region and is subject to ground shaking from an earthquake along major active regional faults. This is common to virtually all development in the San Francisco Bay Area. Development in the plan area and on the site will be subject to review and approval by the City and shall be designed and constructed in accordance with all applicable seismic standards adopted by the City of Redwood City, including the California Building Code (CBC), which requires that a site-specific geotechnical investigation be conducted and report prepared by a licensed professional. The site-specific geotechnical report must provide measures to reduce potentially significant geologic hazards (e.g., expansive and corrosive soils, differential 16
