Moderate

Bullitt County, KY: USDA's soil survey rates 54.1% of the county "Moderate" for shrink-swell potential (3.54% linear extensibility). That's a middle reading: not the sharp swings that crack a foundation outright, but enough that grading and drainage are worth getting right.

Two lots a mile apart in Bullitt 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 Bullitt County will actually do.
