The prospect of a vote today by the Public Authorities Control Board to approve a Jets stadium on the West Side is bleak, officials familiar with continuing negotiations said late yesterday. According to one of those officials, who spoke on condition of anonymity, the legislative leaders who control two of the three votes on the board were considering introducing a resolution at the meeting today calling for the stadium to be built in Queens instead.

“We could put a stadium that I’m sure the Jets could go to as well as the Olympics, in a place like Willets Point in Queens. That’s a fact,” the speaker of the state Assembly, Sheldon Silver, said at a breakfast yesterday held by the Metropolitan Council on Jewish Poverty. Mr. Bloomberg also attended the breakfast, at the Roosevelt Hotel, where the two politicians held a 15-minute closed-door meeting before marching side by side in the Salute to Israel Parade on Fifth Avenue.

A stadium at Willets Point, the neighborhood on the no. 7 line where the Jets’ former home, Shea Stadium, is, “was in the mayor’s original thoughts on the Olympics, and I repeated that this morning to the mayor,” Mr. Silver said.

At a question-and-answer session with reporters later yesterday morning, Mr. Bloomberg said of a stadium in Queens: “In the Olympics, you do not have the right to change the venue. That’s one thing. Number two, there is nobody that I know of that wants to put $1.4 billion into a stadium in Queens.” The Jets are investing more than $1 billion to build the proposed stadium, officially known as the New York Sports and Convention Center, over the Metropolitan Transportation Authority’s Hudson rail yards in Manhattan. Jets executives have said they do not want to move the team, which now plays its home games at Giants Stadium in the Meadowlands in New Jersey, to Queens.

The Public Authorities Control Board, a little-known body controlled by Governor Pataki, Mr. Silver, and the majority leader of the state Senate, Joseph Bruno, must have a 3-0 vote to approve a state expenditure of $300 million for the $2.2 billion stadium project to proceed. Mr. Silver is the critical holdout, officials said.

“The mayor didn’t know what he was getting into with Silver – he is a tough negotiator,” an aide to Mr. Pataki told The New York Sun. The aide said Mr. Bruno – who, like Messrs. Bloomberg and Pataki, is a Republican – is easier to convince to approve the stadium because “he is willing to negotiate to get additional funding for his district.” Mr. Bruno represents upstate Rensselaer. Mr. Silver, a Democrat, represents Lower Manhattan.

Mr. Bloomberg had hoped the board would approve the financing for the stadium before the International Olympic Committee released its evaluation report today on the five cities that are competing to be host for the 2012 Summer Olympics.

According to officials who are familiar with the Bloomberg-Silver negotiations, among the proposals being considered to bolster development in Lower Manhattan are elimination of a commercial rent tax downtown, providing job credits, and slowing commercial development on the West Side so it would not compete with downtown.

Offering too many incentives for Lower Manhattan, however, could drive tenants from Midtown and anger landlords, many of whom are important donors. Instead, the real estate industry is in favor of slowing commercial development on the West Side, according to a real estate insider who is familiar with the negotiations.

That may not be possible, however, because the financing plan for the rezoning of the Hudson Yards is predicated on the construction of office space in 2010, at the same time the Freedom Tower, and office space at the World Trade Center site, is scheduled to be completed.

According to the financing package for the city’s redevelopment of the 59-square-block Hudson Yards area, not including the stadium expenditures, the Transitional Finance Authority is issuing $750 million in short-term bonds for the city, money that is to be paid back with revenue from commercial development. Delaying the construction of office space would postpone the city’s capacity to pay down that debt.

Yesterday afternoon, Messrs. Bloomberg and Silver met again, for less than an hour, at City Hall. Following the meeting, Mr. Silver told reporters, “Nothing’s changed. … I don’t know if there’s been any progress except for the fact that we are talking.” The two politicians are scheduled to meet again this morning.

Emerging from City Hall 10 minutes after Mr. Silver, Mr. Bloomberg responded evasively to reporters’ questions before riding off in an SUV.

“The speaker is a great guy, he’s been a friend of mine for a long time, and we had a very nice get-together,” Mr. Bloomberg said – three days after he sounded exasperated, when a judge dismissed legal challenges to plans for the Jets stadium, saying that those who still had questions about the stadium “either weren’t asking or … weren’t listening.”

The state board’s vote, nevertheless, could be postponed yet again today, as officials said July 6 – when the International Olympic Committee meets at Singapore to vote for host city – is the real deadline.

“We have until July 4, that is the point at which it is really over,” the president of the Partnership of New York City, Kathryn Wylde, said. “The mayor will continue doing everything he can to get the Olympics until then.” Ms. Wylde’s group has supported the mayor’s plans for West Side development, of which the stadium is the centerpiece.

The Olympic evaluation reports are to be made public at 8:30 this morning.

The Pataki aide said that if Mr. Silver does not approve the stadium, it is unlikely he will face a large backlash.

“There have been a number of polls done and there is no overwhelming support for the stadium,” the aide said. “The mayor stuck out his neck on this issue politically, and I almost wonder if he’s ready to pack it up and go home. If he doesn’t, it could hurt him come the fall.” Mr. Bloomberg is running for re-election.
