PA Snow loading

[PCHanson]

I typically evaluate roofs in CT which uses IBC/IRC and has a Supplement listing town by town ground snow load and wind speed. Additionally, even if computed flat roof snow is less, there is a 30 psf minimum.

It appears PA does not provide such a comprehensive listing but requires individual municipalities to list. There do not appear to be building officials in the towns I'm currently interested in, bur rather inspection service firms (and hours to contact them is limited). SO - I'm hoping someone can tell me ground snow load for Gilbert (Chestnuthill Twnshp) and York PA (both appear to be in 90 mph 3-sec wind per IBC/ASCE mapping - similar snow mapping lists them as CS so that isn't helpful). Also, can I use actual PgICtCe*0.7 for roof snow load or is there a minimum?

PA snow loads drive me crazy. I ended up calling the Army (when all else fails, right?) and they sent me the attached document. See if there's a base near your town and good luck.
