Soil survey area

Forsyth County, Georgia

Survey Area GA117• Georgia
The short version

The most common soil here is Madison, on about 49% of the land: a gravelly sandy loam, gritty and crumbly. Cecil and Rion come next.

About 83% of the land drains well, and 3% stays wet for long stretches; groundwater comes within two feet of the surface under 6% of it.

USDA rates 44% of the land very limited for a standard septic drain field, and 41% very limited for homes with basements. That means extra cost or special design, not that it can't be done.

Worth knowing: 7% of the land floods occasionally or more, and bedrock lies within 40 inches under 2% 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.
Entisols
Young soils with little development — found on floodplains, dunes, and steep slopes. Properties vary widely by setting.

What This Means

Building & Foundations

About 41% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.

Septic Systems

About 44% of soils have significant septic limitations, while others are more suitable. A perc test is essential — conditions vary across the area.

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.
