Low

Keya Paha County, NE: USDA's soil survey rates 90.8% of the county "Low" for shrink-swell potential (1.81% linear extensibility). That's as favorable a county-level reading as this dataset produces - standard foundation practice, pending one lot's own geotechnical report.

What Keya Paha County's reading doesn't cover

Two lots a mile apart in Keya Paha 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 Keya Paha County will actually do.

What it costs to find out, versus to ignore it

With Keya Paha County, NE rating "Low", a geotechnical report is still worthwhile before a build, just less urgent than in a high-risk county. 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.
