What this number does and doesn't tell you
This is a countywide, area-weighted figure across every soil survey map unit in Lincoln County, MO - 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.
Lincoln County: conventional vs. engineered cost
