Boulder County, CO Roof Snow Load - Case Study Area
Boulder County, CO: no map figure, on purpose
ASCE 7's own snow load map has no single figure for Boulder 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 08013, population 330,262. 386 US counties get this same case-study treatment; Boulder County is one of them.

Before you rely on Boulder County's number
Treat the Boulder 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. Details: the calculation guide.
