The group’s plans include a new $300 million soccer-specific stadium on a 14-acre site downtown. The team has already secured commitments for more than 10,000 season tickets, it said. And UC Davis Health has signed a multiyear deal to become the sponsor of Sacramento’s jerseys once the team joins M.L.S.

“We always believed in the city and always really had faith in this community as one that would support our league and come out and add to all the passion and momentum that we have for our league,” Garber said.

The Republic currently plays at the 11,000-seat Papa Murphy’s Park and has regularly sold out matches since moving to the stadium in 2014.

Garber first visited Sacramento in 2016. A group led by Nagle submitted an expansion bid in 2017 that was later withdrawn. A new bid was submitted in April.

“Soccer has gotten to a point now where I think you hit the turning point, where I think it’s going to be one of the top two or three sports in America,” Burkle said. “And this was a chance for us to be part of that growth.”
