ground snow loads

ground snow loads
the ibc has regions in the ground snow load tables that are labeled cs (case specific).  these areas are tricky, because not all municipalities are savy enough to provide the structural eor with the required info.
nj utilizes the us army corps of engineers cold regions research and engineering laboratory to develop there isolines for ground snow loads when determining local requirements.  
i was hoping to find that other state maps would have been developed by the army corp.  although i visited the site, no such luck.
does anyone have any leads for me?  especially, for the state of pa?
thanks
