From a deterministic approach (which calculates the maximum site <br /> acceleration assuming that the nearest fault breaks nearest to the site), using an attenuation <br /> relationship from Boore, et. al. 1997 for a VS30 of 750 m/s (Shaw, 2011), the MCE event on <br /> these faults is expected to produce a horizontal Probable Ground Acceleration (PGA) at the site <br /> of 0.438. <br /> Using the newer attenuation relationships of the Next Generation of Attenuation (NGA) <br /> Relationship Project in 2008 (Abrahamson, et.al, 2008, Boore, et. al, 2008, Campbell, et.al, <br /> 2008, and Chiou, et. al, 2008), and considering the faults, distance to the site, and site-specific <br /> configurations; a PGA of 0.528 is calculated for the Great Valley 7 Fault. A shear wave velocity <br /> (V130) of the upper 30 meters of the site was taken to be 760 m/s for the underlying rock <br /> materials at the site (Shaw, 2011 and USGS, 2013). <br /> Review of previous data indicates that the seismic characterization of the site by Shaw (2011) <br /> • utilized a PGA of 0.568. <br /> 5 Geo-Logic <br /> ASSOCIATES <br />
