Little River County, AR Shrink-Swell Risk

What Little River County, AR's soil means for a foundation

Moderate

USDA's SSURGO data puts Little River County, AR's soil at "Moderate" shrink-swell potential, an area-weighted linear extensibility of 5.73% across 40.5% of the county's surveyed land. A real but modest amount of movement - standard foundations usually hold up, but drainage and moisture control around the foundation still matter more than on low-risk soil.

This is a county figure, not a lot figure
