What Lawrence County, OH's soil rates for a septic system

Very limited

In Lawrence County, OH, 95.9% of the surveyed land carries a "Very limited" rating for a standard septic drain field.

Lawrence County, OH is 453.394 square miles with a population of 55,829.

What Lawrence County's reading doesn't cover

This is a countywide, area-weighted figure across every soil survey map unit in Lawrence County, OH - 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 Lawrence County will actually do.

What a system would cost here

With 95.9% of Lawrence 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.
