Haskell County, OK Shrink-Swell Risk

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

Moderate

USDA's SSURGO data puts Haskell County, OK's soil at "Moderate" shrink-swell potential, an area-weighted linear extensibility of 3.38% across 60.2% 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 Haskell County, OK 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 Haskell 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.
