Hunterdon County, NJ Roof Snow Load - Case Study Area
Why doesn't Hunterdon County have a snow load number?
ASCE 7's own snow load map has no single figure for Hunterdon 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 34019, population 131,708. 386 US counties get this same case-study treatment; Hunterdon County is one of them.

Before you rely on Hunterdon County's number
Treat the Hunterdon County figure as a starting point, not a final answer: it assumes standard occupancy, a heated structure and a moderately sheltered site, per ASCE 7-22's own defaults. Exposed terrain, an unheated building or a steeper roof all shift the real number.
For a real application, skip the county number and go straight to the ASCE 7 Hazard Tool - enter your coordinates and it returns a site-specific figure a plan reviewer will recognize. See the methodology guide.
