California State University Sacramento is planning to construct the $73-million Recreation, Wellness and Events Center adjacent to its Hornet Stadium, which will also be remodeled. Funded in part by a $10-million commitment from real estate developer Alex G. Spanos, the proposed 236,000-sf multipurpose center will include an 8,000-seat arena, a new student health facility, rock-climbing wall, swimming pool, athletic courts, bowling center, fitness center, and conference center.
