Yakutat City and Borough, AK Snow Load: Case Study Area
What "Case Study" means for Yakutat City and Borough
ASCE 7's own snow load map has no single figure for Yakutat City and Borough: 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 02282, population 690. 386 US counties get this same case-study treatment; Yakutat City and Borough is one of them.

Yakutat City and Borough's snowfall, most winters
147.3 in. a year: that's Yakutat City and Borough's NOAA 1991-2020 snowfall normal, measured at YAKUTAT STATE AP, AK US (43.5 mi away). That station is far enough away (43.5 mi) that local snowfall - especially at a different elevation or near a lake - can run noticeably higher or lower than this figure. See the density guide.
Before you rely on Yakutat City and Borough's number
Treat the Yakutat City and Borough 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.
