Re: USGS Web address for determining IBC SDC and Base Shear

Thanks Dave,
I was seeking the USGS page to obtain the values needed to determine the SDC base shear values referenced in the October 2007 SEAOC document rather than the link to a site to determine the Latitude and Longitude of the building site as submitted by others. However, I thank all who sent me a response. The key was your USGS Web address listed below which I have bookmarked in my IE favorites.
 
Thanks again to all who responded.

Subject: USGS Web address for determining IBC SDC and Base Shear

I'm sure most of us in California are having nightmares trying to work out the 2006 IBC Seismic and Wind loads that we are gearing up for in January. I received a copy of the SEAOC Seismology and Structural Standards Committee Seismology Publication from October 2007. I know some of those on the committee are subscribers to the list (hint M.C.). I will be posting a few questions that I hope you can help with, but I would like to start with the reference in setion 2 "Determining Forces and Allowable Stress" for IBC 1613  Earthquake Load referenced the S(sub s and sub 1) map parameters from the USGS website. I wish they would have listed the link.
 
Can anyone provide the list with this link and do you know if you can reference by zip code rather than Longitude and Latitude?
 
Thanks
