Kerb grates are installed over storm drains to cover sumps at the edge of pavements or streets to prevent debris and people from going down the drain. They are mostly horizontal, usually rectangular and positioned directly adjacent to a barrier=kerb.
Only use this tag when the grate is also connected to a section of kerb made of the same material. Often grate covered inlets are found next to kerbs, but without an attached section of kerb, these should be tagged as inlet=grate, instead.
It may be useful to use this value on intersection nodes between the drain and barrier=kerb.
How to map
Any object tagged as inlet=kerb_grate should also use the tags man_made=manhole and manhole=drain.
It may be useful to document the shape of the grate with shape=*, and additionally the dimensions with width=* or length=*. material=* and colour=* can also be used.
If the grate is not made of a single material, but instead is covered in the same way as the surrounding surface, the values from the surface=* tag can be used inside of the material=* key (e.g. material=paving_stones). The additional details that follow that tagging scheme can also be used (e.g. paving_stones:pattern=*), however colour=* should be used instead of surface:colour=* (see above).
Incorrect use on a covered gutter
Although it may seem tempting, this tag is not to be used on long covered gutters that also act as a drain. It should only be used on 
nodes where the drain has an attached section of kerb (see example below), and must be combined with the man_made=manhole and manhole=drain tags. No consensus has been made on how to tag this feature but there has been some discussion on the Key:inlet talk page.
