Charlevoix County, MI Roof Snow Load - Case Study Area
Charlevoix County, MI: missing from the map query
The ASCE 7 map service returned no feature at Charlevoix County's survey point - this happens for a small number of shoreline counties (386 nationally are unrated for one reason or another) whose reference point falls just outside every mapped polygon. Not the same thing as a Case Study area - the map likely has a real value a few hundred feet away.

The figure above assumes the case ASCE 7-22 treats as typical: a heated, ordinary-occupancy home on a partially exposed site. Change any of those - exposure, heating, roof pitch, occupancy category - and the real design number moves.
