Haywood County, NC's soil, for a septic absorption field
Very limited
Soil across 90% of Haywood County, NC rates "Very limited" in USDA's septic-absorption-field interpretation. This is the reading that pushes a project toward an engineered system rather than a conventional one, and it covers 90% of Haywood County's land. Haywood County, NC is 553.56 square miles with a population of 63,048.
What Haywood County's reading doesn't cover
Haywood County's rating is an average across the whole county, not a promise about any one lot inside it. A local percolation test, typically $750-$1,850 (around $1,300 typical), is the only way to know what one lot in Haywood County will actually do.
What a system would cost here
With 90% of Haywood 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.
How Haywood County, NC compares
