Very limited

Calhoun County, AL's SSURGO dominant class comes back "Very limited", covering 78.8% of the county.

What this number does and doesn't tell you

Calhoun County's rating is an average across the whole county, not a promise about any one lot inside it. Budget $750-$1,850 for a real perc test on any specific parcel - that's the only figure a permit application accepts.

Calhoun County: conventional vs. engineered cost
