That is because, apart from the entrance to this neighbourhood, Carousel Parkway, this is too new to appear on our legally available sources (TIGER 2017 data).
Therefore, the only way for the names to appear on OpenStreetMap, is for a local mapper (you?) who knows what the names are, or who can travel to and through the area to note them, to edit the map and add their names.
If you are in the area but you do not feel confident enough to risk editing yourself, you can leave more notes like this on each street to give their names.
Then an armchair mapper somewhere else in the world can add these names.
Note that there are many sources from which we may not copy, such as Google Maps, so on-the-ground local knowledge is what is required.
Thanks!
