Soil survey area

Powell and Wolfe Counties, Kentucky

Survey Area KY634• Kentucky
The short version

The most common soil here is Shelocta, on about 17% of the land: a silt loam, smooth, like flour. Gilpin and Latham come next.

About 95% of the land drains well; groundwater comes within two feet of the surface under 5% of it.

USDA rates 87% of the land very limited for a standard septic drain field, and 87% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 8% of the land floods occasionally or more, and bedrock lies within 40 inches under 74% of it.

Soil Orders in This Area

The USDA classifies every soil into one of 12 soil orders. Here are the dominant orders found in this survey area.

Ultisols
Strongly weathered clay soils of the Southeast. Acidic and naturally low in nutrients. Clay subsoil can slow drainage.
Inceptisols
Young but developing soils found in mountains and river terraces. Variable properties — check drainage and bedrock depth.
Alfisols
Moderately weathered forest soils with clay-enriched subsoil. Productive for agriculture, generally good for building and septic.

What This Means

Building & Foundations

About 87% of soils are rated "very limited" for dwellings with basements. Specific challenges include shallow bedrock, steep slopes, poor drainage in some areas, flood-prone areas. A geotechnical assessment is recommended before building.

Septic Systems

About 87% of soils are rated "very limited" for septic absorption fields. Despite good drainage overall, limitations may stem from shallow bedrock, steep slopes, or seasonal conditions. Engineered or alternative systems are frequently required. Always get a professional perc test before purchasing land that needs septic.

Gardening & Agriculture

Well-drained soils on sloped terrain — good for most plants but watch for erosion. Terracing, contour planting, and mulching help retain moisture and topsoil. Drip irrigation is more effective than sprinklers on slopes.
