What Cheboygan County, MI's soil rates for a septic system

Very limited

88.4% of Cheboygan County, MI's surveyed soil comes back "Very limited" in USDA's own SSURGO data, the county's dominant condition for a septic absorption field.

Cheboygan County, MI is 715.284 square miles with a population of 25,964.

What Cheboygan County's reading doesn't cover

Nothing about Cheboygan County, MI's SSURGO figure applies to a specific address - it's a county-wide average. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Cheboygan County will actually do.

What a system would cost here

With 88.4% of Cheboygan 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.
