What is the proper way to deal with roads in stream delineation from a
1m DEM? Should I go in and manually edit the DEM where the streams
will cross a road to the elevation of the lowest neighbor(D8)?  Is
there and automated way to do this?  Thanks for all of your help.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
