Craig County, OK Shrink-Swell Risk

What Craig County, OK's soil means for a foundation

Moderate

USDA's SSURGO data puts Craig County, OK's soil at "Moderate" shrink-swell potential, an area-weighted linear extensibility of 4.22% across 52% of the county's surveyed land. That's a middle reading: not the sharp swings that crack a foundation outright, but enough that grading and drainage are worth getting right.

This is a county figure, not a lot figure

USDA's survey covers the whole of Craig County, OK 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 Craig County will actually do.

Report cost vs. repair cost

With Craig County, OK rating "Moderate", 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.
