Yavapai County, AZ's soil, for shrink-swell risk

Moderate

Yavapai County, AZ: USDA's soil survey rates 58.9% of the county "Moderate" for shrink-swell potential (3.03% linear extensibility). A real but modest amount of movement - standard foundations usually hold up, but drainage and moisture control around the foundation still matter more than on low-risk soil.

What Yavapai County's reading doesn't cover

Two lots a mile apart in Yavapai County can carry different soil, even though they share one countywide reading. The real answer for one lot is still a site-specific geotechnical report, running about $1,000-$5,000 (typically near $2,700).

What it costs to find out, versus to ignore it

With Yavapai County, AZ 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.
