Dillingham Census Area, AK Shrink-Swell Risk

Why Dillingham Census Area, AK isn't rated here

Unrated

This county has no matching soil survey data - too rare a gap to guess at. A local geotechnical report is the only way to know. Dillingham Census Area, AK covers 18,353 square miles and is home to 4,642 people, but the dominant soil here carries no SSURGO linear-extensibility data to report.

This is a county figure, not a lot figure

USDA's survey covers the whole of Dillingham Census Area, AK 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 no SSURGO reading to go on, Dillingham Census Area has no county-level steer either way on foundation risk. A geotechnical report typically runs $1,000-$5,000; a real foundation repair, if it comes to that, runs $5,000-$15,000. The report is the cheap way to find out first.
