East Carroll Parish, LA Shrink-Swell Risk
East Carroll Parish's SSURGO shrink-swell reading
Very High
In East Carroll Parish, LA, 47.7% of the surveyed soil carries a "Very High" shrink-swell rating, 9.96% linear extensibility on average. That's the range most associated with real foundation cracking - stair-step cracks in mortar joints, sticking doors, gaps around window frames - and it typically needs an engineered foundation (post-tension slab, drilled piers), not a standard footing.
Before you rely on this for one address
East Carroll Parish's reading is an average across the whole county, not a promise about any one lot inside it. 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 East Carroll Parish.
Budgeting for East Carroll Parish, LA
East Carroll Parish's soil reading is exactly the case where a report before construction, or before cracks widen, pays for itself.
