Franklin Parish, LA Roof Snow Load - 5 psf
Franklin Parish, LA: your roof's ASCE 7 snow number, in plain English
Franklin Parish's roofs are built to hold 5 psf of snow, the ASCE 7-22 figure a permit reviewer checks first. §7.3.4's low-slope minimum of 5 psf is what actually governs on a flat or low-pitch roof here - higher than the 3.5 psf the base ground-load formula gives.
In depth, not weight: that's roughly 11 inches of fresh, light snow, 4 inches of old, settled snow, or as little as 1 inches of solid ice - snow that heavy is rare here but ice from a freeze-thaw cycle adds up far faster than the depth suggests. This is a modest add-on to standard roof loading - ordinary residential construction carries it without extra bracing.

Before you rely on Franklin Parish's number
Treat the Franklin Parish 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.)
