Gilpin County, CO Roof Snow Load - Case Study Area

What "Case Study" means for Gilpin County

Case study area
No map value

ASCE 7's own snow load map has no single figure for Gilpin 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 08047, population 5,963. 386 US counties get this same case-study treatment; Gilpin County is one of them.

Before you rely on Gilpin County's number

Treat the Gilpin 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. (How this figure is calculated.)
