Otoe County, NE Roof Snow Load - 20 psf
How much snow is too much for a roof in Otoe County, NE?
20 psf: that's what ASCE 7-22 requires a typical heated home's roof in Otoe County to carry. Flat and low-pitch roofs in Otoe County are actually governed by ASCE 7's §7.3.4 minimum of 20 psf, not the 17.5 psf the ground-load formula alone would produce.
Picture it, not just weigh it: 44 in. if it's fresh powder, 16 in. once it settles, or a mere 4 in. if it's ice. This is a meaningful design load - most modern-code homes handle it fine, though an addition, a carport or a flat-roofed section can be a weak spot.

How Otoe County compares
20 psf ranks #999 of 2,758 US counties with a mapped snow load (top 36%) - and #31 of 93 in Nebraska. That's 0.2 psf below Nebraska's own county-average design load of 20.2 psf.
Population 16,591 (FIPS 31131), roughly 40.638°N 96.131°W. The 25 psf ground snow load ASCE 7-22 maps here becomes 20 psf once the code's own design factors are applied.

What this Otoe County figure assumes
This is a county-level reference figure for a typical heated home built to Risk Category II (ordinary residential), on a partially exposed lot - the assumptions ASCE 7-22 itself treats as the default case. A steeper roof, a fully exposed hilltop lot, an unheated structure, or a higher risk category all change the actual number.
Otoe County's permit office wants an address-specific figure, not this county average - the ASCE 7 Hazard Tool is free, takes under a minute, and outputs a PDF most reviewers accept. Details: the calculation guide.
