Representatives of the Anschutz Entertainment Group and Majestic Realty revealed little this morning during a panel discussion on bringing the NFL back to Los Angeles, but moderator Frank Stoltze, a reporter with KPCC radio, let it slip that an AEG rep told him 12 of the 15 members of the Los Angeles City Council are already on board with the project.

That news was somewhat surprising, considering the fact that an environmental impact study has not been completed, the financial details of the plan have not been finalized, and the council’s ad hoc committee on the stadium has yet to meet.

According to Stoltze, the council members who have not committed to the plan are Bill Rosendahl, Paul Krekorian and Paul Koretz.

Los Angeles City Councilwoman Jan Perry joined AEG’s Dan Beckerman, Majestic Realty’s John Semcken and David Pettit with the National Resources Defense Council for the panel discussion hosted by the Pat Brown Institute at the Biltmore Hotel. The two hour-talk on the dueling NFL proposals ranged from environmental impacts, traffic concerns, parking and location.

In AEG’s favor, supporters say the greatest benefit will come from the added Convention Center space that will be built by tearing down the West Hall and replacing it with a building contiguous to the South Hall.

“The project more than anything is a partnership. It’s a partnership with the city, with the NFL, the citizens of Los Angeles, leading environmental organizations and leading business leaders,” Beckerman said. “This needs to be a public-private partnership that works for the city and us, modeled after what has been so successful at Staples Center.”

On the other end of the table, Semcken told the audience that the greatest strength of Majestic’s stadium is its location in the City of Industry, which for people living in the Southland will be more accessible than a stadium in downtown L.A. Unlike Farmers Field which would require the city to float bonds for the Convention Center, the Grand Crossing project will not require funds from the city.

Despite its location, Semcken told the audience that Los Angeles would reap the economic benefits of the stadium. He pointed to Phoenix, Dallas, New York and Miami as cities that have benefited from professional football, even though all of those stadiums are located outside city limits.

“We will have a Super Bowl in Los Angeles and when we do it’s going to create in $600, $700, $800 million in one week and all of that benefit is going to come here from people who don’t live here,” Semcken said.

AEG is owned by billionaire Phil Anschutz. Majestic Realty is owned by billionaire Ed Roski.
