MainPlace Mall Transformation Project 12126.001 <br />3 SEISMIC HAZARD ASSESSMENTS <br />We discussed the geologic and seismic hazards in our geologic and seismic hazard <br />review report (Leighton 2019). A summary of our seismic hazard assessment for the <br />site is presented as follows: <br />3.1 Surface Fault -Rupture <br />Our review of available in-house literature indicates that no known active faults <br />have been mapped across the site, and the site is not located within a designated <br />Alquist-Priolo Earthquake Fault Zone (CGS, 1986; Bryant and Hart, 2007). <br />3.2 Seismicity and Ground Shaking <br />The site is expected to experience moderate to strong ground shaking form <br />earthquakes occurring along the major active and potentially active faults in the <br />region (see Figure 4, Regional Fault and Historic Seismicity Map). Provided <br />below are the code -based design and risk -targeted Maximum Considered <br />Earthquake (MCE) spectral acceleration parameters at 5 percent structural <br />damping for structural design. These parameters were calculated based on the <br />general procedures of the 2016 CBC using the USGS U.S. Seismic Design Map <br />tool (Version 3.1.0). Site -specific spectral acceleration parameters can be <br />developed upon request by the structural engineer. <br />7 �/ <br />Ito <br />Leighton <br />
