This area is mapped as part of a school multipolygon (relation/3255081), which I guess makes sense if you look at
https://josephbracops.be/plan-dacces/
But the site is also a supermarket (check mapillary) and the Erasmus school (http://courserasme.be/erasme/index.php/fr/) as well as an annex of the academie (https://www.aca-anderlecht.be/contact/) in the same way as the Athenée. How would you suggest we map this?
I must admit I'm not a fan of a single multipolygon with parts this far apart...

This road has been marked as having a cycleway nine years ago. Looking at the imagery, it's probably correct, but it's probably a track on one side of the road - not on both

Zijn deze twee reservaten (relatie 3244400 en 3251840) niet hetzelfde?
Overigens zijn de waterplassen in dit gebied wellicht wel degelijk deel van het reservaat (dus mogen die geen inner zijn van de relatie die het reservaat beschrijft)

There's a parking mapped here, but the access road has a traffic sign prohibiting all vehicles. Is it really a parking then?

there's probably more paths from here to the west and then north

looking at strava, it seems there's a path going southwest here

This segment is oneway towards N246. Is it oneway until the end? Is there an exception for cyclists, mofa, moped?

There's a path clearly visible here, heading north. On Strava, there's a vague trace towards Rue D'Odeghien 200. To be surveyed.

Doublecheck housenumber: was mapped as 30, but is 74B in ICAR
