Jefferson County steep-slope & wetlands.
Jefferson County pairs the flat Lake Ontario plain and Thousand Islands granite shore with the western rise of the Tug Hill Plateau. Slope concentrates along the Tug Hill scarp and Black River gorges, while the lakeshore's Golden Crescent holds some of the largest protected wetland marshes in the state.
DRAW OR UPLOADJeffersonCounty doesn't publish public parcel boundaries yet, but elevation and wetlands still cover it completely — draw your site on the map or upload a georeferenced survey (DXF/DWG) and the analysis is identical.
