Demote most "hamlet"s in Columbia to landuse=residential, make (or add) the village nodes into "place=neighbourhood"s, and demote a few nearby "hamlet"s that I'm reasonably certain are subdividions, not hamlets.

Better alignment along part of the Little Patuxent River, and tracing the stream that feeds into Lake Elkhorn and all the streams that feed into that one.

More pathways in Columbia, in Oakland Mills, Long Reach, and Owen Brown. Some of these replace non-ODbL-clean ways.

Been meaning to do the road alignments in this little almost-cut-off neighborhood. (MD 32 and US 29 were not kind to its connectivity.)

Should be the last of the ODbL cleanup in River Hill. I'm deleting a bunch of nodes that were created or modified by an anonymous non-CT-agreeing contributor that I subsequently moved.

Investigating and clearing the obvious ODbL-problematic ways along 695 and 83.

Waterways that flow through River Hill, principally the Carroll Branch and the streams that feed into it.
