Moderate
Crosby County, TX: USDA's soil survey rates 49.8% of the county "Moderate" for shrink-swell potential (4.38% 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 Crosby County's reading doesn't cover
