Harrison County, KY Shrink-Swell Risk

Harrison County, KY's soil, for shrink-swell risk

Moderate

Harrison County, KY: USDA's soil survey rates 82.8% of the county "Moderate" for shrink-swell potential (3.94% 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.

What Harrison County's reading doesn't cover

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

What it costs to find out, versus to ignore it

A geotechnical report runs $1,000-$5,000, typically around $2,700. Foundation repair, if a specific lot turns out to differ from the county average, runs $5,000-$15,000.
