Wyoming County, NY Roof Snow Load - Case Study Area

Wyoming County, NY: no map figure, on purpose

Case study area
No map value

ASCE 7's own snow load map has no single figure for Wyoming 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 36121, population 39,588. 386 US counties get this same case-study treatment; Wyoming County is one of them.

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. (How this figure is calculated.)
