Thanks guys! Yep, nice and warm here, beautiful day outside my window right now.
The stage is placed on one leg of an existing intersection of two streets. Both streets were previously closed to vehicle traffic. Now they want to add a stage at one side. So yes, the street is still the public way, just with a stage located in it. Yes, in the attachment, the stage (48" high) is shown as the structure, while the roof above projects beyond. Hope this helps clarify the proposal for you.
Appreciate all the feedback!
