There’s a couple of Notes questioning the name that OSM has mapped here:
https://www.openstreetmap.org/note/2498777
https://www.openstreetmap.org/note/2499002
As best as I can see from web searches (but anybody who knows better is welcome to correct me):
- the name currently mapped seems to be only a proposed name. It has local support but Ealing Council (which owns the site) has not yet used that name as far as I can see
- the name registered with Royal Mail is Warren Farm Sports Centre, but is not in active use as a sports centre
OSM has it mapped with operator=https://www.warrenfarmnaturereserve.co.uk but a web search does not find any recent indication that Ealing Council has formally appointed a third party to operate the site. But perhaps most significant is that their History page ends with this note:
I am not local to the area, but if I was, and on the basis of what is presented there, I would certainly be adding my support.
But my feeling is that it is premature and incorrect for OSM to map a “proposed name” when it seems that “constructive discussion” has not yet begun with the landowner. It is not OSM’s job to prejudge a proposal, no matter how much local support it might have.
Equally though, it shouldn’t be mapped as a sports centre if there is no longer a sports centre there – even if there is still signage that says that.
Accordingly, my suggestion would be that it should at present be mapped just as Warren Farm with possibly Warren Farm Nature Reserve as an alt_name to help those searching under that name.
Likewise, the operator tag should probably be changed to a different keyword unless/until there is evidence that https://www.warrenfarmnaturereserve.co.uk is in some way “operating” the area. Meanwhile, that web site is certainly providing useful information about the site, so perhaps information= or website= would be appropriate for it.
Editors Milhouse and Hanwellweather have previously been involved in mapping the site, so I’ll invite them to comment. But it would also help to have a balanced view from other editors who are either in the area or have time to check out the history in detail.
