For the 'Roller Haven', there are trail closed signs at the northern end, and it looks like the park does not want people to use that trail, and is trying to restore that section of forest

The chance of it being re-added is very unlikely. The habitat/environment was restored.

So for Hilltop why don't you correct your mistake and do what you suggested?

Well for Hilltop the boundary is not complete. Since the road cuts through the park, I only had a chance to add the eastern half. I still had the western part and then had to tie them in with a multipolygon relation.

And you were quick to change it to "your way" before the complete boundary was even added.

Onatru Park and Preserve is one park, that is the official name of the place. There is just the road that cuts through the park. The name should be corrected and the place has sports fields so that makes it a park
