According to Bing Streetside from 2015, they're lowered without tactile marking. I've updated them as such and hopefully that's correct.

Hi poetixmind, and welcome to OpenStreetMap!
Is there actually a park here, or is it just a commons area for what looks like a private community?
Also, out of curiosity, are you editing the map to use with a game, like Pokemon Go?
Thanks for contributing!

Hi vogelfreier,
The TIGER data was imported years ago to complete the road network in the United States. The `tiger:zip_left` and `tiger:zip_right` tags provide the zip code (`addr:postcode`) for the corresponding side of the street. They're usually accurate and can be used for determining the zip code for addresses, but are 11 years old and sometimes don't correspond correctly. In Durham County and some nearby counties, we have imported all of the addresses anyway, so in this area they're essentially useless. I just remove them with the other TIGER tags when I review the roads.

Translated with Google:
Hallo vogelfreier,
Die TIGER-Daten wurden vor Jahren importiert, um das Straßennetz in den Vereinigten Staaten zu vervollständigen. Die Tags `tiger: zip_left` und` tiger: zip_right` geben die Postleitzahl (`addr: postcode`) für die entsprechende Straßenseite an. Sie sind normalerweise genau und können zur Bestimmung der Postleitzahl für Adressen verwendet werden, sind aber 11 Jahre alt und stimmen manchmal nicht richtig überein. In Durham County und einigen nahe gelegenen Landkreisen haben wir ohnehin alle Adressen importiert, sodass sie in diesem Bereich im Wesentlichen unbrauchbar sind. Ich entferne sie nur mit den anderen TIGER-Tags, wenn ich die Straßen überprüfe.

Thanks Frederick for the explanation. I'll go over all aspects of the POIs when I edit in the future.

Great, thanks! I hadn't come across these before and they looked strange. The proposal looks quite useful, actually.

Hi,
there were a few (4) nodes in this changeset on the rails tagged with `Wall=yes`. What I would read as `barrier=wall` is not valid on nodes (although there are over 2,000 used for some reason), and a wall over a rail line would be impassable anyway.
I changed them to `barrier=yes` - see changeset/72790102.
If there is a more appropriate tag please do update them.
Thanks,
Will

Hi Friedrich,
I noticed a couple buildings tagged with `addr2:` and `addr3:`.
I'm not sure if these addresses should go on separate features or just enumerated within the regular `addr:` tag, but as far as I know no consumer will recognize these as addresses.
It seems to be the buildings contained in relation/1060497 (relation/1060497) but I might have missed some.
Thanks,
Will

Hi Mark, thanks for the edit.
Do you have a source for this being a park? On satellite imagery it looks like a section of wooded area, with no infrastructure or sense of being a park area.
Thanks,
Will

Hi Ann,
Are you running the group using #JPMC-July20 ?
If so please check the quality of your mappers' work before having them submit.
Let me know if you have any questions.
Thanks,
Will

Hi bathis,
Thanks for the addition. I've changed this from a residential road to a driveway. TIGER can be wrong sometimes and often extends roads past where they end down someone's private driveway.
See changeset/72442522.

Thanks for noticing. I see there are also some incorrect instances of payment:cheques and payment:check in the database. I'll fix all of them soon.

Hi,
Is way/15571815 no longer called Emmons Road?

Is way/658361115 no longer a park? If so, what should it be tagged as?

Hi Aglis, please check the ways that you are editing. Many of the rivers are duplicates of rivers that I drew almost a year ago. Many small canals or streams are also tagged as rivers, which is incorrect.

Hi Rottrokc, and welcome to OpenStreetMap!
Please don't use the admin_level tag for parks. It is used for administrative boundaries, such as countries, states, and counties. Please don't duplicate things, ways 686193129 and 686193138 are the exact same boundary with different tags.
Also, do you have a source for these park boundaries, or are they only drawn from satellite imagery?
Let me know if you have any questions.
Happy mapping!
Will

Hi Chris, please do not use the name tag as a descriptor. It is for objects that are actually named something. Also, please refrain from using building=house unless you know that the building is actually being used by a family for living.

Hi Chomba,
Thanks for contributing to OSM and HOT!
I see that you have duplicated part of R766 with way/686319650. Please avoid tracing over existing data.
Let me know if you have any questions.
Thanks,
Will

Hi,
It seems that you duplicated your own tertiary road with way/686324267.
Please don't trace over existing data.
Thanks,
Will

I have re-added the Wikipedia tag (69647559). Let me know if you have any questions.

Hi VMRTexas, and welcome to OpenStreetMap. Thanks for contributing!
Are these numbers actual addresses for the houses or just numbers you are using to ID them? If it is the latter, please remove them as OSM is only for real-world data. If they are house numbers, please add them using the 'Adress' field in iD (the default editor that you are using), or by adding the tag `addr:housenumber=*`.
Let me know if you have any questions.
Happy mapping!
Will
