So i have reason to believe that the snow loading around King County area may have - or - may be changing...
I was speaking to an engineer for a roofing system that we have designesd in the Bellevue area, and she was suggesting that the 25psf snow white paper did not apply to our project or jurisdiction.
I went online, and was able to download a snow load map that has the Isolines on it ( King County Ground Snow Load Analysis - updated Feb 2005)... ground snow load is determined by multiplying the elevation of the site by the (interpolated) isoline. In my particular case, a quick spot check revealed that my ground snow loads were heading up close to 45psf! that starts getting up past the 25psf roof loads in a hurry.
The King County maps can be found here...(G:\Codes\Snow Loads)
If anyone has any additional knowledge or experience with snow loads around the Puget Sound Area - please reply to this post...
