Obtaining Seismic Ss and S1 design values from USGS website during US Government Shutdown

Due to the government shutdown, the Seismic Ss and S1 design values are currently not available on the USGS website. SK Ghosh Associates (SKGA) has created a spread sheet based upon the 2009 NEHRP seismic maps (used with the 2012 IBC) providing the  Ss and S1 design values associate with various degrees of Longitudes and Latitudes: http://skghoshassociates.com/resources/miscellaneous/

This is a temporary link until the USGS website is available.
