CITY OF SANTA ANA <br />Planning and Building Agency <br />Seismicity <br />Approved <br />FOR PERMIT ISSUANCE <br />lf <br />as er ID: <br />The subject site is located in Southern California, which is a major eauMprone <br />ae:. <br />zone. Therefore, the owner(s) of this property should be aware of the-,ismic risks-_. <br />associated with being located in this zone. <br />The Soil Site Class D Default can be used for the soils underlying the subject site. <br />The Seismic Design Category D can be used for the site. <br />The following seismic parameters obtained from the computer program https:// <br />seismicmaps.org prepared by SEAOC [Structural Engineers Association Of <br />California] in conjunction with California's Office of Statewide Health Planning and <br />Development [OSHPD] ) in accordance with ASCE7-16 can be used for the site. <br />• Fa = 1.2 <br />• Fv = null* <br />• Mapped Spectral Accelerations Values: <br />SS = 1.321 (for the short period of 0.2 second) <br />S1= 0.471 (for the 1-second period) <br />• Maximum Considered Earthquake Spectral Response Accelerations: <br />SMS = FaS, = 1.585 (for the short period of 0.2 second) <br />SM1= FvSI = null* (for the 1-second period) <br />• Design Spectral Response Accelerations: <br />SD, = 2/3 SMS = 1.057 (for the short period of 0.2 second) <br />SD1 = 2/3 SMl = null* (for the 1-second period) <br />• PGA = 0.553 <br />* Please see ASCE 7-16, Section 11.4.8. <br />Please see APPENDIX C for additional seismic parameters, as needed. <br />Note: In general, the structural consultant of record for this project should review the <br />seismic parameters provided in this report and the 2022 CBC to evaluate the seismic <br />design. Final selection of design coefficients should be made by the structural consultant <br />based on the local laws and ordinances, expected structure response, and the desired level <br />of conservatism. <br />Page 3 <br />
