What Fannin County, GA's soil rates for a septic system

Very limited

In Fannin County, GA, 86.1% of the surveyed land carries a "Very limited" rating for a standard septic drain field.

Fannin County, GA is 387.106 square miles with a population of 25,854.

What Fannin County's reading doesn't cover

USDA's survey covers the whole of Fannin 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 Fannin County will actually do.

What a system would cost here

With 86.1% of Fannin County rating "Very 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.
