Ramsey County, MN has no septic-suitability rating on file

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. Ramsey County, MN covers 152.259 square miles and is home to 542,015 people, but the dominant soil here carries no SSURGO absorption-field interpretation to report.

This is a county figure, not a parcel figure

Two lots a mile apart in Ramsey County can carry different soil, even though they share one countywide rating. A site-specific perc test, usually $750-$1,850, is what a health department will actually require before permitting a lot in Ramsey County.

System cost, conventional vs. engineered

With no SSURGO rating to go on, Ramsey 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 Ramsey County is exactly what a perc test settles.
