Pickett County, TN Shrink-Swell Risk

What Pickett County, TN's soil means for a foundation

Low

USDA's SSURGO data puts Pickett County, TN's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 1.63% across 83.6% of the county's surveyed land.

This is a county figure, not a lot figure

USDA's survey covers the whole of Pickett County, TN 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 Pickett County, TN rating "Low", a geotechnical report is still worthwhile before a build, just less urgent than in a high-risk county.
