Very limited

Santa Rosa County, FL: USDA's soil survey calls 57.8% of the county "Very limited" for a septic leach field.

What this number does and doesn't tell you

Santa Rosa County: conventional vs. engineered cost

57.8% of Santa Rosa 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.
