Very limited
Wichita County, KS's SSURGO dominant class comes back "Very limited", covering 79.2% 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 719 square miles, home to 2,072 people.
What this number does and doesn't tell you
Two lots a mile apart in Wichita County can carry different soil, even though they share one countywide rating. Budget $750-$1,850 for a real perc test on any specific parcel - that's the only figure a permit application accepts.
Wichita County: conventional vs. engineered cost
