I would like to find a way to convert an Edge of Pavement layer into polygons that would represent the total paved area. It's a large shapefile, covering some 100 sq miles or so, so doing anything manually is out of the question. I've tried the Feature to Polygon tool but got the result below...

I know this is a pretty basic question but I couldn't find the answer myself, so here I go: I need variable buffer widths depending on the surface area of the polygon (city) size. For example: A polygon sized 100 km2 should have twice the buffer than a polygon sized 50 km2 (which would be...
