This PTNY map uses a color coded key to identify paved, non-paved and street surface areas. I might question it's timeliness for accuracy, but, worse case, any changes to the path surface would be improvements.
The KEY doesn't specify, but I believe the solid green lines on the map are paved, the dotted green lines are stone dust.
