I mentioned this in the note, but to get ahead of any confusion: the City of Arnold is coterminous with the civil township of Arnold. Both share the same land area which is an enclave of the unincorporated Windsor Township.

This means Arnold (both city and township) does not border Saint Louis County. Unfortunately, this was the case on OSM for a long time which was a major factor in my edit.

I quadruple checked this one. I know that the statistics metadata should probably be updated, I just wanted to get the geometry in place for now.

Please let me know if there is any problem, and I will be happy to help. Also reactivate #3625698 note if it's relevant to the problem/concern.

No it isn't. I corrected this in a subsequent changeset.

I treated the signposts as canonical and put any other names (such as those with unnecessary spaces in them from county GIS data) in alt_name tags.

Note to self: JOSM search type:way & highway=* & name~".*Pl$" with case sensitive

All of these came from GNIS. The first three I listed went untouched as hamlets for 15 years, but Lakeside was just imported from GNIS. I set them to suburbs earlier, but now I think neighbourhood is a better fit.

On second thought, should these be neighborhoods since Arnold itself can be considered a suburb of St. Louis? Either way, hamlet didn't seem right to me.

I don't remember the exact time, but a new one was opened at Ozark

And I am aware the park boundary is glued to the roadway. It was like this before, and I will fix it if it's not fixed next time I can look at it.

Specifically I meant the convenience store. The pumps are still Phillips 66.

Also Bing StreetSide shows the sign at the entrance reads "Meramec Energy Center".

Got it, thanks.

For context, I added those originally, but then I second-guessed myself after reading the Armchair Mapping wiki page. It says "backyard [...] swimming pools are probably best left unmapped." But now I know about the access tag.

Cheers!
