Coweta, Heard, and Troup Counties, Georgia
The most common soil here is Cecil, on about 34% of the land: a sandy loam, gritty and crumbly. Madison and Pacolet come next.
About 95% of the land drains well; groundwater comes within two feet of the surface under 9% of it.
USDA rates 30% of the land very limited for a standard septic drain field, and 29% very limited for homes with basements. That means extra cost or special design, not that it can't be done.
Worth knowing: 11% of the land floods occasionally or more, and bedrock lies within 40 inches under 3% 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.
What This Means
Building & Foundations
About 29% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.
Septic Systems
About 30% 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.
