Union County, OR Roof Snow Load - Case Study Area

What "Case Study" means for Union County

Case study area

No map value

Union 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.

Union County, FIPS 41061, is home to 26,058 people - one of 386 US counties ASCE 7 itself routes around a map figure for.

Read this before you rely on it

Union 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 Union County's county-wide figure. (How this figure is calculated.)
