If I'm correct, it looks like the Briggs Stage renovations will include an area for tables, and an upper deck that resides above a vending area. There will be two permanent beer "tent" structures behind the bleachers, and tables as well. Thankfully, some of the surrounding structures will have shaded areas as well.
The Briggs Stage is just south of the Marcus Amphitheater. It certainly sees its share of walking traffic. As Briggs signed on for the next decade, it makes sense that they would build something that is going to last at least that long.
