Moderate

Le Flore County, OK: USDA's soil survey rates 62.8% of the county "Moderate" for shrink-swell potential (3.57% linear extensibility).

What Le Flore County's reading doesn't cover

Two lots a mile apart in Le Flore County can carry different soil, even though they share one countywide reading. A site-specific soil report, usually $1,000-$5,000, is what an engineer would actually pull before designing a foundation on a lot in Le Flore County.

What it costs to find out, versus to ignore it
