Soil survey area

Twiggs County, Georgia

Survey Area GA289• Georgia
The short version

The most common soil here is Orangeburg, on about 27% of the land: a loamy sand, gritty and loose. Bibb and Bonifay come next.

About 72% of the land drains well, and 24% stays wet for long stretches; groundwater comes within two feet of the surface under 20% of it.

USDA rates 64% of the land very limited for a standard septic drain field, and 42% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 22% of the land floods occasionally or more.

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.
Alfisols
Moderately weathered forest soils with clay-enriched subsoil. Productive for agriculture, generally good for building and septic.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.

What This Means

Building & Foundations

About 42% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 64% 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.
