Lamoille County, VT Roof Snow Load - Case Study Area
Why doesn't Lamoille County have a snow load number?
ASCE 7's own snow load map has no single figure for Lamoille 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 50015, population 26,248. 386 US counties get this same case-study treatment; Lamoille 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.)
