HOUSTON – The final price tag for a state-of-the-art stadium in Inglewood proposed by Rams owner Stan Kroenke could reach $2.66 billion, team officials have told NFL senior staff and league owners.

The stadium cost after financing is $800 million more than the previously reported cost for the stadium, and would make it the most expensive stadium ever built by more than $1 billion.

Kroenke has also told NFL officials and owners that he has spent $5 million on negotiations and arbitration with St. Louis officials and that Rams officials have met regularly with officials from a stadium task force appointed by Missouri Gov. Jay Nixon but those discussions have not produced a viable local stadium option.

Commissioner Roger Goodell told the league’s 32 owners over the weekend that the current stadiums for the Rams, Chargers and Raiders are no longer adequate and that local officials in St. Louis, San Diego and Oakland have either failed to provide a formal plan for a local stadium option or submitted to the league plans containing political and fiscal uncertainties.

The 8.5 million square foot stadium on the former site of the Hollywood Park race track is one of at least three relocation options for the Los Angeles market the league’s 32 owners will consider during a special NFL meeting Tuesday and Wednesday in Houston.

The Chargers and Raiders are asking the league to approve their relocation to a $1.75 billion stadium in Carson next to the 405 freeway. Cowboys owner Jerry Jones, a Kroenke supporter, has also submitted a proposal calling for the league to approve the Rams and Chargers playing in the Inglewood stadium. Chargers owner Dean Spanos is vehemently opposed to moving to Inglewood.

The NFL’s six-owner Committee on Los Angeles Opportunities is expected to request a vote on the relocation options following a discussion of the various proposals in Houston. If none of the proposals receive the required votes from 24 of the 32 owners for relocation approval the owners will have further discussion and potentially additional votes.

To be considered for relocation, the three franchises had to sign off on 18 requirements set last week by the Los Angeles, finance and stadium committees. The requirements range from agreeing to a $550 million per team relocation fee, to not sue either the league or its owners regardless of the Houston vote, securing temporary facility arrangement in their new market, relinquishing rights to their previous market, using only the name Los Angeles in branding and marketing the team, and paying a 20 percent tax on any revenues generated by the sale of shares of the team after moving to Los Angeles.

The latter requirement will impact a Carson relocation. Disney chairman and chief executive Robert Iger can purchase a minority share of either the Chargers or Raiders as part of a deal in which he agrees to become chairman of Carson Holdings, LLC, the company that will oversee the design, construction and marketing of the stadium. Barry Sternlicht, chairman and CEO of Starwood Capital Group, also has an option to purchase a small share of the Chargers. The option is part of the deal in which the Chargers and Raiders purchased the Carson parcel from Starwood.

The $2.66 billion price tag for the Inglewood stadium includes financing costs. The 70,000-seat venue will be privately funded with personal seat licenses and a $200 million loan from the league’s G-4 stadium program.

New Jersey’s MetLife Stadium, home of the NFL’s Giants and Jets, opened in 2010 with a $1.6 billion price tag making it the world’s most expensive stadium built to date. The Cowboy’s AT&T Stadium in Arlington, Texas, the so-called “Jerry’s World,” and the 49ers new Levi’s Stadium in Santa Clara each came with $1.3 billion tabs. The new Yankee Stadium came at a cost of $1.5 billion.

Spanos has repeatedly told NFL officials he isn’t interested in the Inglewood site and remains committed to Carson and the Raiders as partners.

“I have reviewed the letter you received dated December 1, 2015 from Stan Kroenke,” Spanos wrote in a Dec. 7 letter to the Los Angeles committee, referring to a Kroenke proposal that a second team partner with the Rams on football-related activities at the Inglewood stadium. “Nothing in Stan’s letter gives me any reason to reconsider my partnership with Mark Davis and our stadium site. I firmly believe that the proposal we have jointly made is in the best interests of the entire League and is in complete compliance with the League’s relocation policies.”
