The arena will also host college basketball and hockey, boxing, a Brooklyn Nets preseason game and open practices.

Bowl seating would be reduced to 13,000, but could expand to 14,500 with floor seating and shrink to 4,000 for smaller events.

Outside the arena, Ratner’s development team plans a movie theater, several restaurants, an amphitheater — which would host free entertainment as well as ice skating in the winter — a 2,000-seat Filmore Club run by Live Nation Entertainment, and a monument dedicated to Nassau County veterans.

Monday’s legislative session will begin at 1 p.m. in the Peter J. Schmitt Memorial Legislative Chamber, inside the Theodore Roosevelt Executive and Legislative Building, at 1550 Franklin Ave. in Mineola.
