Thanks for making these improvements. A couple comments:
- is the surface of the bridge you added actually "ground" or is it wood?
- the name you added for the portage node is better suited for the description tag
Happy mapping

No problem. Happy mapping!

I like the idea. If I'm understanding correctly, I think 10 could be too many separate levels of prominence and it'd be hard to establish a guideline for what separates a landmark=9 from a landmark=10

What does landmark=3/10 mean? I don't see anything about that convention on the wiki

Fulton Market is the name on street signs for this section, which you can see in Streetside imagery. It's also used on the official Chicago GIS maps: https://gisapps.chicago.gov/mapchicago

For routing purposes, it's better to leave the sidewalk as connecting and ending at the road

The crossing on Kinzie is definitely concrete. Please double check your changes

Both sidewalk-alley crossings are clearly concrete in Aerial and streetside imagery

Instead of mulch, I think surface=woodchips is the standard tag, see surface=*. Looks good otherwise

Does this laundromat have a name?

No problem!

The field name is probably a reference to Babe Ruth League baseball (https://en.wikipedia.org/wiki/Babe_Ruth_League#Babe_Ruth_Baseball) rather than named after Babe Ruth directly

"bicycle=Not Specified" is not a standard tag. For informal paths, it's probably best to leave the bicycle key unspecified

Hey, Green roofs are usually mapped as a tag on the building rather than a separate area. You can read about this more here green_roof=*

Thanks for adding back. I mistakenly thought the building already had the same address

Did you mean to name the cycle paths and the route "Lincoln Park Fitness Course"? It seems like way/1016303660 should be the only thing with this name

From the project website it looks to still be in progress, although the last update is from February. The pedestrian detour also appears to have changed

Got it. Thanks for clarifying

What do the done=yes tags on the nodes on S Halsted indicate?

The Wiki says "The main difference from areas tagged as tourism=hotel is that resorts sell their recreation services, with housing as an additional service, but a hotels sells its housing services and recreation is just an additional service." Poplar Haus is primarily a lodging provider, so I think tourism=hotel is correct. leisure=resort is also not rendered
