Have you ever heard of the 2021 flood disaster? Everything here was destroyed! We at OSM have tagged this as a construction site; it just happens to look brown, but that doesn’t mean it’s a “mudflat.” By the way, the colors have nothing to do with the actual on-site situation—they’re simply a design choice made by the map designer. There are several map styles that we as OSM members cannot influence; in other map styles, the park may appear in a different color. This says nothing about the actual data in our database! But since the flood disaster was 5 years ago and most of the damage to the park has been repaired, and large parts of the park are recognizable as such again, I’ve changed it.
