The partners plan to build three to five venues. Aside from the large sports stadium, which could have a retractable roof, the venues could potentially range from a 100-seat amphitheater to a 6,000- to 8,000-seat venue, said Dean Marks, principal and general counsel at Sterling Bay. That would allow Live Nation to schedule a mix of musicians, comedians and other entertainers ranging from up-and-coming acts to world-famous performers.
