Very limited
In LaGrange County, IN, 96.8% of the surveyed land carries a "Very limited" rating for a standard septic drain field.

What LaGrange County's reading doesn't cover
This is a countywide, area-weighted figure across every soil survey map unit in LaGrange County, IN - never a reading for one specific parcel. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in LaGrange County will actually do.
What a system would cost here
With 96.8% of LaGrange 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.
