Fenced playgrounds

We are working on an urban school renovation (SSc2=yes), and I am wondering if having the playgrounds and other outdoor areas behind fences affects this credit at all - are they still "pedestrian oriented" if typical pedestrians/passers-by cannot access them? We appear able to obtain the credit 2 ways: If I add up every scrap of non-paved area on site, we make it, but this includes counting things like in-ground tree planters completely surrounded by playground, which seems dicey. If I count all of our playgrounds and outdoor classroom/lunch area, we also achieve the credit under the "Pedestrian Oriented Hardscape" provision, but I'm not sure these qualify, as they certainly aren't public areas like the plaza given in the example, or an open, generally accessible playing field. Maybe I'm overthinking it, but any thoughts on which calculations would be more reasonable to submit? Thanks,
