Richland County, OH Shrink-Swell Risk

What Richland County, OH's soil means for a foundation

Low

USDA's SSURGO data puts Richland County, OH's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 2.67% across 60.2% 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 Richland County, OH at once, not any single address. A site-specific soil report, usually $1,000-$5,000, is what an engineer would actually pull before designing a foundation on a lot in Richland County.

Report cost vs. repair cost

With Richland County, OH 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.
