Crittenden County, AR Roof Snow Load - 10 psf
Crittenden County, AR: your roof's ASCE 7 snow number, in plain English
Crittenden County's roofs are built to hold 10 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. Flat and low-pitch roofs in Crittenden County are actually governed by ASCE 7's §7.3.4 minimum of 10 psf, not the 7 psf the ground-load formula alone would produce.
In depth, not weight: that's roughly 22 inches of fresh, light snow, 8 inches of old, settled snow, or as little as 2 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. A modest addition to standard roof loading. Ordinary residential construction handles this without extra bracing.

Before you rely on Crittenden County's number
Treat the Crittenden County figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.
For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. (How this figure is calculated.)
