Bland County, VA Shrink-Swell Risk
What Bland County, VA's soil means for a foundation
Low
USDA's SSURGO data puts Bland County, VA's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 2.07% across 81.4% 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 Bland County, VA at once, not any single address. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Bland County will actually do.
Report cost vs. repair cost
With Bland County, VA 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.
