In December 2021, The Douglas County School System Board of Education approved an allocation for a new multipurpose arena at the site of the district's old central office building on Highway 5.

The new facility will have seating for 6,000 guests, making it large enough to host graduation ceremonies, which are currently held about 40 minutes away at the University of West Georgia coliseum in Carrollton. It will also be used for additional school system events and for rent by outside organizations, including tournaments for basketball, wrestling, volleyball, soccer, lacrosse, rugby, field hockey, gymnastics, cheer and dance and will provide a world-class stage for touring concerts and shows. Legacy Arena is expected to open in 2024.
