Bradley County, AR Shrink-Swell Risk
What Bradley County, AR's soil means for a foundation
Low
USDA's SSURGO data puts Bradley County, AR's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 2.02% across 85.6% of the county's surveyed land. That's as favorable a county-level reading as this dataset produces - standard foundation practice, pending one lot's own geotechnical report.
This is a county figure, not a lot figure
USDA's survey covers the whole of Bradley County, AR at once, not any single address. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).
Report cost vs. repair cost
With Bradley County, AR 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.
