snow loads in mercer county nd
i am working on a building that is located in the portion of mercer county, nd that lies in the area designated as "cs" on the ground snow loads map in asce 7-05. the foot note to this map (pg 84, asce 7-05) indicates that a "site specific case study is required to establish ground snow loads". has anybody done such a study before? or are results of such a site specific study for this area available at any source that you can refer me to?
thanks for your help!
have you tried the obvious; the mercer county nd building officials ?
i'm actually trying to get as much info. as possible on cs ground snow so if you don't mind posting what you find out much appreciated.
regards

call the locals
i've found calling the military to be helpful.  if there's a base anywhere around there, the military will have a design snow load that they use for their building design.
the army corps of engineers sent me a useful document and i've attached it here.  north dakota is on page c-9.
