Hello.
Please note that the usual nyc sidewalks should be tagged as just "surface=concrete". "concrete:plates" value is intended for situations such as bridges or other paths were the places were pre-cast off-site and installed as a whole at a location. With the nyc sidewalks it's usually poured in-place.
