[OSM-newbies] What's the easiest method to "snap" an area boundary to adjacent ways?

Hi Russell

These wiki pages may help clarify:

http://wiki.openstreetmap.org/wiki/Tag:waterway%3Driverbank

If the river is just a centre line i would attach the boundary to it. 
Some renderers (such as mapnik) make use of the width=* tag to give 
width to a line.

If the riverbank is drawn, there should still be a centre line to 
indicate the flow direction, so you can still attach the boundary to it.

Hope that helps
