Four days after St. Louis Rams owner Stan Kroenke announced plans to build an NFL stadium in Los Angeles, St. Louis on Friday unveiled a proposal for a new $900 million stadium.

David Peacock, a former top executive at Anheuser-Busch who is leading the stadium team, told reporters at the presentation, “The Rams are our team. We believe with this kind of plan the Rams will continue to be our team.”

City officials said they had been unable to reach Kroenke to discuss the plan.

No representatives of the Rams were at the announcement Friday, but the team issued a statement: “The St. Louis Rams have worked for many years with several agencies and commissions and their senior management responsible for stadium facilities in St. Louis. This includes multiple discussions with the Governor’s recently formed NFL Task Force. We received the Task Force materials shortly before the press conference. We will review them and speak with the Task Force representatives.”

The stadium plan reportedly has been in the works since 2012, when an arbitrator ruled that the Rams would be free to leave Edward Jones Dome after the 2014 season if the now 20-year-old stadium were not among the top quarter of NFL facilities.

In November, Missouri Gov. Jay Nixon asked Peacock and attorney Bob Blitz to design a plan “to ensure St. Louis remains an NFL city for years to come.”

On Friday, Peacock presented sketches for a 64,000-seat, open-air stadium a few blocks from Edward Jones Dome.

Kroenke, who took over the Rams in 2010, announced Monday that he had partnered with Stockbridge Capital Group to finance an 80,000-seat stadium in Inglewood, Calif.

The NFL has said no team will move to Los Angeles this year, but the Rams are expected to exercise their option this month to convert their lease to a year-to-year deal.
