Nez Perce County, ID Roof Snow Load - Case Study Area
What "Case Study" means for Nez Perce County
Nez Perce 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.
Nez Perce County, FIPS 16069, is home to 42,847 people - one of 386 US counties ASCE 7 itself routes around a map figure for.

Read this before you rely on it
Nez Perce 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.
