Site Class is required to determine the Seismic Design Category for a structure. <br /> The Site Class is based on the upper 100 feet of the site profile defined by a weighted average <br /> value of either shear wave velocity, standard penetration resistance, or undrained shear strength <br /> in accordance with Chapter 20 of ASCE 7. <br /> Description Value <br /> Site Class CI <br /> Site Latitude 47.97802098 <br /> Site Longitude -122.119190456 <br /> Ss -Short Period Spectral Acceleration, Site Class B 2 1.297 g <br /> S1- 1-Second Period Spectral Acceleration, Site Class B z 0.493 g <br /> Fa -Short Period Site Coefficient z 1.000 <br /> F„-1-Second Period Site Coefficient 1.507 <br /> PGA-ASCE 7, Peak Ground Acceleration 0.534 g <br /> Responsive ■ Resourceful ■ Reliable 14 <br />
