Eureka County, NV Roof Snow Load - Case Study Area

Eureka County, NV: no map figure, on purpose

Case study area
No map value

ASCE 7's own snow load map has no single figure for Eureka County: the terrain is complex enough that the code (§7.2) requires an elevation-specific study rather than a county-wide value. That is the map being accurate, not a data gap.

FIPS 32011, population 1,877. 386 US counties get this same case-study treatment; Eureka County is one of them.

Eureka County: average annual snowfall

Eureka County sees about 47.3 in. of snow most winters, per the EUREKA, NV US station's 1991-2020 NOAA normal. 35.9 mi is a real gap between Eureka County and its nearest reporting station, so local snowfall can diverge from this figure, especially near elevation changes. See the density guide.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.

A building permit needs the number at your exact address, not the county average - the free ASCE 7 Hazard Tool returns that from your coordinates in about a minute and produces a PDF a plan reviewer will accept. Details: the calculation guide.
