What Washington County's reading doesn't cover

Two lots a mile apart in Washington County can carry different soil, even though they share one countywide reading. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Washington County will actually do.
