Beaver County, UT: no USDA soil-survey match
Unrated
The dominant soil here (often already-developed urban land) carries no septic-suitability interpretation from USDA - too rare a gap to guess at. A local percolation test is the only way to know. Beaver County, UT covers 2,582.912 square miles and is home to 7,424 people, but the dominant soil here carries no SSURGO absorption-field interpretation to report.
This is a county figure, not a parcel figure
USDA's survey covers the whole of Beaver County, UT at once, not any single address. A site-specific perc test, usually $750-$1,850, is what a health department will actually require before permitting a lot in Beaver County.
System cost, conventional vs. engineered
With no SSURGO rating to go on, Beaver County has no county-level steer either way on system cost. Nationally, conventional systems run $3,000-$8,000 and engineered alternatives run $10,000-$40,000 - which one applies to a lot in Beaver County is exactly what a perc test settles.
