Jones County, TX Septic Rating
Jones County's SSURGO septic rating
Very limited
Jones County, TX's SSURGO dominant class comes back "Very limited", covering 89.5% of the county. 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 929 square miles, home to 20,850 people.
What this number does and doesn't tell you
This is a countywide, area-weighted figure across every soil survey map unit in Jones County, TX - 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.
Jones County: conventional vs. engineered cost
89.5% of Jones County carrying a "Very limited" reading changes the realistic budget here. Conventional systems run $3,000-$8,000 where they pass; where they don't, engineered alternatives (mound or aerobic treatment, whichever the health department requires) run $10,000-$40,000 - budget toward the higher figure until a perc test says otherwise.
