Moderate

Lafayette County, AR: USDA's soil survey rates 40.5% of the county "Moderate" for shrink-swell potential (5.73% 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 Lafayette County's reading doesn't cover
