Wayne County, PA Roof Snow Load - Case Study Area
Wayne County, PA: no map figure, on purpose
ASCE 7's own snow load map has no single figure for Wayne 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 42127, population 51,419. 386 US counties get this same case-study treatment; Wayne 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. See the methodology guide.
