I noticed some reference material on Seismic Safety Commission using the Seismic Zones for areas of California. I thought seismic zones are from the UBC days? The latest code references ASCE 7 which requires design considerations be made for the following parameters:
Spectral response
Occupancy category
Site category
These considerations lead to a Seismic Design Categories SDC which should replace the old UBC "seismic zones."

Do we still need to go by the older seismic zones that Seismic Safety Commission is referencing in its outdated property guides?
