Low risk About 2% of Rutland County's soil area is high shrink-swell (expansive) clay — 1.4 times the Vermont average of 1%, and far below the national average of 17%. That places it #4 of 14 Vermont counties for foundation soil risk.
Share of the county's ~604,500 acres of USDA-mapped soil with linear extensibility ≥ 6% in the top meter (SSURGO).

Expansive clay swells as it takes on water and shrinks as it dries, and that repeated movement is what lifts and drops a foundation unevenly — opening stair-step cracks, racking door and window frames, and, left unmanaged, cracking slabs and footings. Rutland County's exposure is minimal. With just 2% high-expansive soil, expansive clay is unlikely to be the main driver of foundation movement in Rutland County. Settlement here more often traces to drainage, fill, tree roots, or original construction — worth a diagnosis before paying for clay fixes.
| County | High-risk soil | |
|---|---|---|
| Higher risk → | Chittenden County | 3% |
| This county | Rutland County (#4 of 14) | 2% |
| Lower risk → | Franklin County | 1% |
For context, the average Vermont county is 1% high-expansive soil and the average U.S. county is 17%.

At this risk level the clay is rarely the culprit, so a proper diagnosis is the first dollar to spend. See the full foundation repair cost guide for method-by-method pricing.
Risk metrics are computed from USDA SSURGO soil survey data (linear extensibility of soil components, area-weighted by county). Soil varies lot to lot — this is county-scale context, not a substitute for a site-specific geotechnical or structural assessment.
