What Page County, VA's soil rates for a septic system
Very limited
Soil across 86.3% of Page County, VA rates "Very limited" in USDA's septic-absorption-field interpretation.

Page County, VA is 310.017 square miles with a population of 23,686.
What Page County's reading doesn't cover
Page 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 Page County will actually do.
What a system would cost here
With 86.3% of Page 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.
