Moderate

Deuel County, SD: USDA's soil survey rates 84% of the county "Moderate" for shrink-swell potential (3.72% linear extensibility).

What Deuel County's reading doesn't cover

Two lots a mile apart in Deuel County can carry different soil, even though they share one countywide reading. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Deuel County will actually do.

What it costs to find out, versus to ignore it
