Moderate

Schuyler County, IL: USDA's soil survey rates 59.8% of the county "Moderate" for shrink-swell potential (3.59% linear extensibility).

What Schuyler County's reading doesn't cover

Two lots a mile apart in Schuyler County can carry different soil, even though they share one countywide reading. 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 Schuyler 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.
