Hoonah-Angoon Census Area, AK Snow Load: Case Study Area
Why doesn't Hoonah-Angoon Census Area have a snow load number?
ASCE 7's own snow load map has no single figure for Hoonah-Angoon Census Area: 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 02105, population 2,312. 386 US counties get this same case-study treatment; Hoonah-Angoon Census Area is one of them.

Before you rely on Hoonah-Angoon Census Area's number
Treat the Hoonah-Angoon Census Area 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.)
