Septic suitability in Phelps County, NE
Very limited
Phelps County, NE: USDA's soil survey calls 75.9% of the county "Very limited" for a septic leach field. That reading means a conventional system is a poor bet here - it's already USDA's strictest "very limited" bucket, not a partial constraint. The county spans 540 square miles, home to 9,042 people.
What this number does and doesn't tell you
This is a countywide, area-weighted figure across every soil survey map unit in Phelps County, NE - never a reading for one specific parcel. Budget $750-$1,850 for a real perc test on any specific parcel - that's the only figure a permit application accepts.
Phelps County: conventional vs. engineered cost
