Moderate

Wilson County, KS: USDA's soil survey rates 41.4% of the county "Moderate" for shrink-swell potential (5.73% linear extensibility).

What Wilson County's reading doesn't cover

Two lots a mile apart in Wilson 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 Wilson County.

What it costs to find out, versus to ignore it
