The large apartment building should have been added as a landuse, not a large building. I have corrected it. :)

"Q" can be used to square the buildings. Additionally, if you could take time to outline the buildings a little more accurately, that would be awesome.

Also added sidewalks, crossings (unmarked, marked), parking lots, water reservoirs, powerlines.

The fields should not be named using descriptive tags.

Please do not use descriptive tags to describe a feature... such as:
osm.org/way/1111879384/history

Reverted/corrected in:
osm.org/changeset/136321976

Again, do not add trees/woods as buildings. This is not correct use of OSM. Please bare in mind that OSM is used for navigation and emergency response, not just a golf game, so mapping things correctly is important. This edit has been reverted/correct in part orfull.

Addressed in changeset:

osm.org/changeset/136321853

Again, do not add trees as buildings. This is not correct. Also, please do not add cartpaths as service roads. They are cartpaths and should be tagged as paths.

Features have been reverted or correct in part or full.

What source do you have for this pipeline since it isn't visible form above? And what is it? Does it really go beneath all the buildings?

FYI, you don't need to add "Area=yes" tags to the features like parking lots or buildings as this is redundant.

FYI - individual sections of parking shouldn't be mapped as seperate parking lots since it is all one lot.

Buildings can be squared using "q"

What in the world is going on here?!? Numbers for names but different from addresses?

Plus, none of them are squared with right-angle corners?

Most of these "abandoned" railways do not have anything on the ground with no ground truth. Specifically:
osm.org/way/99652729

These "abandoned" railways should be moved to OHM and removed from OSM since only things that actually exist on the ground and can be verified should be mapped.

Furthermore, these railways definitely do not cross I-70.
