Venango County parcel viewer: Oil City, Franklin, vacant land, and industry

Who usually opens this map
Buyers and heirs check boundaries. Industry and timber interests look at larger polygons. Floodplain along the river is a common reason to open the map.
Vacant parcels and buildable ground
Vacant parcels show in older boroughs and as larger rural tracts. Confirm flood and municipal zoning before treating an empty polygon as a build site.
Local industry and land use
Energy heritage, manufacturing, timber, healthcare, and small-town retail still shape land use.

Not a survey. Screen maps are for reference. Legal boundaries, fencing, and title work need recorded plats, deeds, and a licensed surveyor.
