Sounds basically reasonable to me.  The page does not make it clear if
this is just a place you can put a hose in, or if the piping is
pre-installed.  What I'm talking about is a red 3 or 4" pipe that runs
from under the middle to the edge with "FD Water Source #6" sign or some
such.   Maybe that's what

  emergency=fire_hydrant + fire_hydrant:type=suction_point - strange alternative tagging

is all about.

But I don't see getting that straightened out as a bar to what you want
to do.

That's exactly the kind of thing I meant.  So no objections to your
plans here.

So sounds like you are not going to remove landing_site?

In addition to real helipads and merely planned places, I have also seen
a crazy-extra-wide turning circle at the end of a road to a ~mountain
hiking trail, with paint marks that are obviously about helicopters.
But I am 99% sure this is for medevac only -- I think they just expect to need
it more often given the trail steepness, and there wasn't anything
close, so they cleared and paved a 100' circle (and you can park around
the edge only, IIRC).
