For unpaved roads with a width of less than 5 meters but still allow a
vehicle crossing propose to use:
highway = service
service = alley
surface = unpaved
source = bing
For most appropriate playgrounds is
leisure = playground
The border flood is best taken in the field with GPS and yes, label it
floodprone = yes
It is possible to combine with the labels proposed by

> I spoke to one mapper on the ground in Dakar who told me the
> areas/ways that Harry mentioned in a conversation a couple days ago
> are used mostly by kids as play areas; so leisure=pitch ? or
> playground ? (although there's no equipment ?).
> Lastly, there are some areas that are more floodprone than others.
> Personally, I would hesistate for others to tag them ([based solely on
