McKean County, PA Roof Snow Load - Case Study Area
Why doesn't McKean County have a snow load number?
McKean 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.
McKean County, FIPS 42083, is home to 39,478 people - one of 386 US counties ASCE 7 itself routes around a map figure for.

Read this before you rely on it
McKean 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 McKean County's county-wide figure. See the methodology guide.
