Ohio Unglaciated Appalachian Plateau Sandstone & Steep Hillsides

Dominant Soil Order: Inceptisols / Ultisols
Parent Material: Pennsylvanian-Permian Sandstone, Siltstone, Shale and Coal Measures over Dissected Plateau Bedrock

Southeastern Ohio sits outside the glacial boundary, and the landscape shows it: narrow ridge crests, steep hollows, and bedrock close to the surface almost everywhere. Slopes over 15 percent cover 45-85 percent of land in Athens, Hocking, Morgan, Vinton, Monroe and neighboring counties: among the steepest county profiles in the Midwest: so site selection, access drives, and bench cutting dominate excavation planning. Soils are thin, stony silt loam weathered from sandstone and shale, digging easily in the upper foot but hitting rock on a large share of lots (bedrock within 50 inches occurs on roughly 20-55 percent of land). Perched water above shale layers, seep lines on hillsides, and spoil that will not compact without moisture control are recurring issues. The payoff: expansive clays are almost absent, hydric soils are rare, and septic systems are typically conventional trench systems on benched sites. The trade is rock work and slope engineering instead of wet-soil problems.

Geographic Footprint:Ohio's unglaciated southeast (Athens, Hocking, Perry, Morgan, Muskingum, Guernsey, Belmont, Monroe, Washington, Gallia, Jackson, Vinton, Meigs, Lawrence, Scioto, Pike, Ross, Fairfield, Coshocton, Tuscarawas, Harrison, Jefferson, Carroll, Columbiana, Noble) is sandstone hill country: thin soils, bedrock near the surface, and steep slopes that shape every septic and foundation dig. Rock excavation and benching are the norm, shrink-swell is negligible.

Compliance & Permitting

Earthwork Regulations & Permit Thresholds

Stormwater & Erosion Control
Ohio EPA NPDES Construction Stormwater General Permit OHC000006 (effective April 23, 2023, expires April 22, 2028). Authorizes stormwater from construction disturbing one or more acres, statewide; less than one acre covered if part of a larger common plan. NOI and SWP3 required at least 21 days before construction (45 days in Big Darby Creek and parts of Olentangy watersheds).

Administers NPDES stormwater discharge coverage for land-disturbing construction activities.

State Threshold:1.00 Acre
Local Threshold:Follows state

Area-specific FAQ

Do I need to call before digging in Adams County?

Yes. You should contact Ohio Utilities Protection Service at least 2 working days before any digging so underground lines can be marked.

How deep do footings need to be in Ohio?

In Ohio, footings typically need to extend below the frost line, which is around 36 inches here. A local contractor will confirm the code requirement for your site.
