I am watching this topic to see what staff says. I also had that thought that it may have been removed as being part of the bigger playground. But I also would have submitted this separately signed area separately per this clarification:
I can’t think of any other reason for it to be removed except property owner request, or a mistake that it belongs to the school across the street, but if that were the case, why would they leave the playground?
Watching with interest. Staff does always respond to appeals, fyi.
