Soil Regime ProfileEPA Ecoregion 67 (Ridge and Valley)

Ridge and Valley Folded Shale & Sandstone

Dominant Soil Order: Ultisols / Inceptisols
Parent Material: Tilted and Folded Sedimentary Shale, Siltstone, Sandstone & Dolomite

The Ridge and Valley physiographic province consists of alternating parallel ridges and valleys created by intensely folded and faulted Paleozoic sedimentary rock strata. Valley floors are underlain by easily weathered shales, siltstones, and carbonate rocks that can typically be excavated with heavy single-shank rippers without blasting. However, structural bedding planes tilt at steep dip angles; cut slopes made parallel to the rock strike risk catastrophic planar sliding along lubricated shale layers. Ridge shoulders feature hard sandstone caprock that requires heavy breaker attachments. Shallow refusal depths in ridge residential developments require rock saws for utility trenching, and conventional septic drainfields frequently require engineered mounded or drip-dispersal systems due to shallow restrictive rock layers.

Area-specific FAQ

Do I need to call before digging in Loudon County?

Yes. You should contact Tennessee 811 at least 2 working days before any digging so underground lines can be marked.

How deep do footings need to be in Tennessee?

In Tennessee, footings typically need to extend below the frost line, which is around 12 inches here. A local contractor will confirm the code requirement for your site.
