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 percolation test is the only way to know. Dillingham Census Area, AK covers 18,353.188 square miles and is home to 4,642 people, but the dominant soil here carries no SSURGO absorption-field interpretation to report.

This is a county figure, not a parcel figure

Nothing about Dillingham Census Area, AK's SSURGO figure applies to a specific address - it's a county-wide average. A site-specific perc test, usually $750-$1,850, is what a health department will actually require before permitting a lot in Dillingham Census Area.

System cost, conventional vs. engineered

Dillingham Census Area carries no dominant soil rating, so there's no shortcut here - it comes down entirely to the site-specific test. Nationally, conventional systems run $3,000-$8,000 and engineered alternatives run $10,000-$40,000 - which one applies to a lot in Dillingham Census Area is exactly what a perc test settles.
