What this means

What the soils in Hall County mean for gardens, lawns and septic systems

For your garden

Typical topsoil in Hall County is strongly acidic: pH 5.5 (most land between 5.5 and 5.8). Most vegetables and lawn grasses do best around 6.0 to 7.0, so lime is often needed; blueberries, azaleas and rhododendrons like it as it is.

Loamy topsoil (loam, silt loam and similar) covers 100% of the land: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is sandy loam (45% of the land).

97% of the land is moderately well to excessively drained, which suits most garden plants.

For your lawn and yard

Most land is in hydrologic groups B and C, where rain soaks in at a moderate pace.

For a septic system

For conventional septic absorption fields, NRCS rates 49% of the land in Hall County very limited, 51% somewhat limited and 0% not limited.

Statewide, 68% of the land is very limited, so Hall County is less restrictive than typical.

Flooding is mapped on 6% of the land (3% occasional, 3% frequent).

Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.

Septic absorption fields

NRCS rating for conventional drain fields

The rating looks at the soil from 24 to 60 inches deep: permeability, depth to a seasonal water table or bedrock, flooding and slope. “Very limited” means at least one feature is unfavorable enough that a conventional field is hard to make work.
