Low

Edgecombe County, NC: USDA's soil survey rates 94.8% of the county "Low" for shrink-swell potential (1.43% linear extensibility). That's as favorable a county-level reading as this dataset produces - standard foundation practice, pending one lot's own geotechnical report.

What Edgecombe County's reading doesn't cover

Two lots a mile apart in Edgecombe County can carry different soil, even though they share one countywide reading. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).

What it costs to find out, versus to ignore it

With Edgecombe County, NC 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.
