Near here, there's one office building built lake-side, that has a car park
as the ground level of the building. The car park has a line painted round
it, about half way up the wall (1.2 - 1.5 m's) labelled as the 1-100 year
flood level.

Another river side shopping centre has signs down the river end of the car
park, warning that that part of the park floods during heavy rain.

The first one is only a potential, so you wouldn't map that as flood prone,
but you would the second, but how?

You could add flood_prone=yes to the car park tag but that will show the
whole car park as affected, whereas it's only the bit down this end that
has a problem. Would drawing a separate area & marking that as
flood_prone=yes work?

Thanks
