What Tom Green County, TX's soil means for a foundation

Moderate

This is a county figure, not a lot figure

USDA's survey covers the whole of Tom Green County, TX at once, not any single address. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).

Report cost vs. repair cost

With Tom Green County, TX rating "Moderate", a geotechnical report is still worthwhile before a build, just less urgent than in a high-risk county.
