Sunflower County, MS Shrink-Swell Risk

Sunflower County's SSURGO shrink-swell reading

Very High

In Sunflower County, MS, 51.4% of the surveyed soil carries a "Very High" shrink-swell rating, 10.01% linear extensibility on average. Ground that moves this much routinely produces the classic expansive-soil symptoms: diagonal stair-step cracking, doors that stick seasonally, uneven floors. A standard footing is a poor bet here.

Before you rely on this for one address

Sunflower 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 Sunflower County, MS

With Sunflower County, MS rating "Very High", the gap between finding out early and finding out late is the whole decision.
