Leelanau County, MI Roof Snow Load - Case Study Area

Leelanau County, MI: missing from the map query

Not returned by the map
No value

The ASCE 7 map service returned no feature at Leelanau 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.

Leelanau County, FIPS 26089, population 22,871.

Before you rely on Leelanau County's number

Treat the Leelanau 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.)
