Moderate

Nemaha County, KS: USDA's soil survey rates 59.7% of the county "Moderate" for shrink-swell potential (5.65% 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 Nemaha County's reading doesn't cover
