Moderate

This is a county figure, not a lot figure

USDA's survey covers the whole of Staunton city, VA at once, not any single address. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Staunton city will actually do.

Report cost vs. repair cost

With Staunton city, VA rating "Moderate", a geotechnical report is still worthwhile before a build, just less urgent than in a high-risk county. A geotechnical report runs $1,000-$5,000, typically around $2,700. Foundation repair, if a specific lot turns out to differ from the county average, runs $5,000-$15,000.
