Pemiscot County, MO Shrink-Swell Risk

What Pemiscot County, MO's soil means for a foundation

High

USDA's SSURGO data puts Pemiscot County, MO's soil at "High" shrink-swell potential, an area-weighted linear extensibility of 8.31% across 43.8% of the county's surveyed land. This is enough movement to matter: a standard footing can hold up here, but usually only with real moisture management, not by default.

This is a county figure, not a lot figure

USDA's survey covers the whole of Pemiscot County, MO at once, not any single address. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).

Report cost vs. repair cost

Given Pemiscot County's rating, spending a few thousand now is the way to avoid spending tens of thousands later. The report ($1,000-$5,000) is what tells you whether Pemiscot County's county-level reading applies to your lot; the repair ($5,000-$15,000) is what it costs if you skip that and find out from the cracks instead.
