What Greene County, GA's soil rates for a septic system
Somewhat limited
56.9% of Greene County, GA's surveyed soil comes back "Somewhat limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field. It's a soil condition contractors work around routinely, with a bigger field or added fill, rather than one that forces an engineered system outright. Greene County, GA is 387.517 square miles with a population of 21,091.
What Greene County's reading doesn't cover
USDA's survey covers the whole of Greene County, GA at once, not any single address. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Greene County will actually do.
What a system would cost here
With 56.9% of Greene County rating "Somewhat limited", a standard gravity system is not a safe assumption here. The engineered-system range, $10,000-$40,000 (mound or aerobic treatment), is the more realistic number to plan around, against $3,000-$8,000 for a conventional system on the rare lot that passes.
