Moderate

Jackson County, WV: USDA's soil survey rates 55.2% of the county "Moderate" for shrink-swell potential (3.68% linear extensibility).

What Jackson County's reading doesn't cover

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