Calculating percentage of a polygon's area and using it to buffer a polyline

Hi all,

I've got a tricky one (or maybe not!). I've been asked to calculate the percentage of a series of polygons' area, and then distribute that resulting area within each polygon, but along the features of a polyline file. In this case, it would be 15% of the total area of the polygon. My first idea was to use the buffer by field option to calculate the buffer area for each polygon (which would solve the first have of the problem), but I kept getting an empty output area error (still not sure why).

The particular example I'm working with is a series of parcels (the polygons) and a roads file (the polyline), where we're hoping to be able to allocate 25% of each parcel to a specific purpose along the roads.
