27.3 acres on Larmon Forks Road. Where could a septic field go?

How to read this
Every soil in this square is rated “Very limited” for a conventional septic absorption field. USDA uses that rating when at least one soil property works against a standard drain field. It does not say a permit is impossible. It says which problems the soil scientist and the system designer will have to work around.
The limits are not all equal, so this page groups them. The grouping is ours, built only from the USDA reasons:
Design limits: seepage or slow percolation. Usually changes the size or type of the field.
Slope: the soil is typically steeper than 15%. Fields need benching or a flatter pocket.
Hard limits: frequent flooding, a water table within about 3 ft, rock within about 3 ft, or slopes over 25%. Hard to permit at all.
What this page is not
It is not a perc test or a soil evaluation. In Georgia the county health department decides, based on a soil report from a qualified soil scientist on site.
USDA maps soils at about 1:24,000. A polygon can hide a pocket of better or worse soil a few hundred feet wide.
The parcel lines are not public in this sample. The dashed circle covers 27.3 acres around a sample point. The real lot is a different shape.
“Where to test first” marks ground outside the hard limits with a terrain slope under 15%. It is a place to start digging test pits, not an approval.
