Clinton County, MO Shrink-Swell Risk

Clinton County's SSURGO shrink-swell reading

High

In Clinton County, MO, 62.1% of the surveyed soil carries a "High" shrink-swell rating, 6.03% linear extensibility on average. Soil at this level can crack a standard foundation without moisture-control measures - consistent watering near the foundation, correct grading, root barriers - or added structural design.

Before you rely on this for one address

Clinton County's reading is an average across the whole county, not a promise about any one lot inside it. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).

Budgeting for Clinton County, MO

Clinton County's soil reading is exactly the case where a report before construction, or before cracks widen, pays for itself.
