Garden County, NE Shrink-Swell Risk
What Garden County, NE's soil means for a foundation
Low
USDA's SSURGO data puts Garden County, NE's soil at "Low" shrink-swell potential, an area-weighted linear extensibility of 0.62% across 99.4% of the county's surveyed land. That's as favorable a county-level reading as this dataset produces - standard foundation practice, pending one lot's own geotechnical report.
This is a county figure, not a lot figure
USDA's survey covers the whole of Garden County, NE 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 Garden County, NE rating "Low", 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.
