The BPOE is defined as a Life Safety performance level during a BSE-1E seismic event[the BSE-1E is defined as an earthquake hazard with a probability of exceedance of 20 percent in a 50-year exposure period—alternately defined as having an average return period of 225-years]and a a Collapse prevention performance level during a BSE-2E seismic event[the BSE-2E is defined as an earthquake hazard with a probability of exceedance of 5 percent in a 50- year exposure period—alternately defined as having an average return period of 975-years] 10/10/2018 Design Maps Summary Report / '111-t USGS Design Maps Summary Report User-Specified Input Building Code Reference Document ASCE 41 Retrofit Standard, BSE-1E (which utilizes USES hazard data available in 2008) Site Coordinates 45.40185°N-13, 122.74618°W Site Soil Classification Site Class D _Rs "Stiff Soil" Berton. , r t i 10� Tigdr( , a )- I�, Lif swegott £ 9�t, , iii r' s 4" Slr ►ct {f r/ Oregon City Neuuberc� _ . ` USGS-Provided Output Sxssse-ie Ss,201so 0<291 g 0.456 g 5i,20150 0.109 g Sxi,ose-1E 0.258 g Hortrant.tI Peet ram VerticalSpectrum 4 ,,iii ,,In .,lei tO, ±,,{„ ube 0'4, its, Lai la+, Ip, 7H21, 14, LU, 144 e.
