What Gallatin County's reading doesn't cover

Two lots a mile apart in Gallatin County can carry different soil, even though they share one countywide rating. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Gallatin County will actually do.
