if these two buildings way/372920331 and way/372920330 are both the courtyard marriott, suggest creating an area for the hotel instead of just tagging one of the building with the hotel tags...

are there two starbucks pois located here or only one? See: node/4259274319 and node/7776688304 . If only one, merge the two together to remove duplicate information but verification is needed.

building parts for this building are showing up as buildings but should instead be showing up as building parts... is the building=yes tag on the wrong part of the relation or something here?

There are two polygons here, one for Fort DeRussy Beach Park way/509354370 and one for Fort De Russy relation/7409047, unclear if there are actually two separate entities here or if there is instead just one entity... but if there is only one then suggest removing the beach park area and keeping the more comprehensive Fort De Russy area. In addition, even though Fort De Russy is open to the public, it is still considered a military facility technically so in addition to the park tag it could also have a military landuse tag...

all these building areas should be turned into building parts (building:part=yes) instead of building=yes and a larger area for the casino should be made so that not all these building parts have the casino tag, some clean up needed here

building should be separated into separate structures

per buffalo dept of parks and rec data on the open data portal, the land that the gallery is located on here is technically part of Delaware park, suggest updating park boundary to encompass the museum grounds here

all these landuse areas should be detached from road centerlines in order to preserve change history of roads and areas and to make the landuse areas more accurate to the non-road land area
