Shoshone County, ID Roof Snow Load - Case Study Area
What "Case Study" means for Shoshone County
Shoshone County sits in the mountain-west terrain where ASCE 7-22 §7.2 itself declines to give a contour figure - elevation changes too fast over short distances there for one number per county to mean anything. The code requires a site-specific study for a building here, not a look-up.
Shoshone County, FIPS 16079, is home to 14,074 people - one of 386 US counties ASCE 7 itself routes around a map figure for.

How much it actually snows in Shoshone County
Most winters bring Shoshone County roughly 15.3 in. of snow - NOAA's normal at THOMPSON FALLS PH, MT US, 29.8 mi off. 29.8 mi is a real gap between Shoshone County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. (fresh vs. packed vs. ice explains why.)
Read this before you rely on it
Shoshone County's number above is ASCE 7-22's default case, not a custom calculation: ordinary residential occupancy, heated, sited on ground that's neither fully sheltered nor fully exposed. Any one of those changing - pitch, exposure, heating, occupancy - moves the real figure.
Nothing here substitutes for an address-level number. Get one free, in about a minute, from the ASCE 7 Hazard Tool using your own coordinates rather than Shoshone County's county-wide figure. See the methodology guide.
