The boundary is a mess.

osm.org/way/362988271/history#map=18/39.89900/-76.85147

Please take a look: osm.org/way/86310964/history

The buildings you added have horrible GPS offsets.

I'm not sure if you are local here or not. Please consider fixing all these junks by taking a look at the background MD 6 inch imagery. Do not use Bing, it is a troublemaker.

osm.org/changeset/102144648#map=19/39.66589/-78.93138

It makes no sense, fixed:

osm.org/way/434371180#map=19/39.69497/-78.87849

Next time creating roundabouts please consider circularizing it.

osm.org/way/688256044/history#map=19/39.57194/-75.72047

Please consider using MD 6inch to redo the buildings.

T355 is not a major road, reverted.

This does not look like an airport. It does not provide service to general public.

If you do not have any opposition, I'm going to remove it.

Maryland does not favor any ESRI source, please do not add building with incorrect offset here.

osm.org/way/776307238#map=19/39.69982/-78.17642

Please do not add a building with name "unknown building". It does not make sense.

osm.org/changeset/91466375#map=19/39.69978/-78.17921

I didn't know what happened but I add a road type to this line.

osm.org/way/766581611#map=19/39.69951/-78.17776

This is not a building passage.

osm.org/way/904150622#map=19/39.70006/-78.18408

Please carefully read wiki before adding waterways.

Your previous edit damaged the map.

osm.org/relation/8257094#map=18/39.70971/-78.56730

May I ask where does the name come from?

osm.org/way/545824501#map=16/40.5560/-78.4244

I'm glad you started disconnecting them because they have caused huge troubles to others.

But your work is not done yet, I've disconnected all remaining nodes.

The driveway you added to 18014 does not reflect the reality. NAIP clearly shows the path. I've corrected it but please be careful in the future.

osm.org/way/845242498#map=19/39.61869/-76.65658

What exactly is this?

osm.org/way/38502925/history#map=15/40.0491/-77.5123&layers=N

Please do not use Bing imagery to edit Maryland, it only makes map worse. The buildings you added do not match the reality.

This area has a lot of features with questionable offsets. My advice is avoid using Bing from now.

I changed the road back to public. It is not a private access road.
