Athens County septic services.

No county body in Athens County sets lot size or setbacks: the county has adopted no zoning regulations. What it does hold at county level is subdivision and floodplain regulations, which apply to property splits and to any development in the flood hazard area, and dividing land into parcels of less than five acres is what triggers subdivision review. Anything more restrictive than that comes from a township or a municipality.

Big run (Superior High Quality Water, entire listed length); Federal creek (Superior High Quality Water, Hyde fork (RM 16.21) to the mouth); Joes run (Superior High Quality Water, entire listed length). Ohio EPA's general permit for discharging household systems (OHK000004, Part II.C.2(e)) bars a new discharge to any of these, or to a tributary within one mile upstream. On those parcels the off-lot discharging route is closed and the system has to be a soil-absorption design, whatever the lot looks like.

The dominant constraint here is slope (80.2% of rated soils), followed by bedrock close to the surface (54.3%).
