The Empire State Development Corporation took the first step in approving a $1.4 billion stadium on the West Side for the New York Jets.

The state agency unanimously approved putting its general project plan for the New York Sports and Convention Center, the stadium’s formal name, up for public comment.

The move comes a week before New York City submits its bid for the 2012 Olympic Games, in which the Jets stadium would double as the Olympic stadium. The next step in the state’s process is a public hearing and a 30-day comment period, sometime within the next month.

While much of the information in the plan released yesterday was already public, some new details of financing emerged. While the project is to be financed with $800 million from the Jets and $300 million each from the city and the state, the Empire State Development Corporation has no budget of its own and needs the Legislature to appropriate the state’s $300 million contribution. According to a footnote in the plan, if the Legislature fails to allocate the funds, the city will assume the state’s debt, with the state repaying that debt through direct payments or land transfers.

“This is an outrage,” the assemblyman who represents the area, Richard Gottfried, said. “Even if the Legislature refuses to support the plan, the governor intends to use some kind of three-card monte so the city picks up the state’s share of the plan.”

The footnote also specifies that as part of the state’s payback to the city, the state could help finance the $2 billion the city plans to make available to the Metropolitan Transportation Authority’s capital plan for the construction of the No. 7 subway line. The subway extension is part of a larger Hudson Yards plan, which includes rezoning the area for residential and office development and extending the Jacob K. Javits Convention Center.

“This is an unorthodox use of funds and should be subject to some sort of public discussion,” a senior analyst at the Fiscal Policy Institute, James Parrott, said yesterday.

In addition, the new plan discloses that of the $800 million the Jets are responsible for investing in the project, $400 million is to be raised through tax-exempt bonds in the form of payments in lieu of taxes.

Mr. Parrott, who met with the Jets yesterday, said the payment would break down to $32 million a year for 30 years.

“I thought the city was supposed to be earning tax revenue from this project, so why are we issuing the Jets tax-exempt bonds?” Mr. Gottfried queried.

Of the remaining money, $150 million will come from an investment from the National Football League, with equity and other private financing generating the remaining $250 million.

“The city and state want public amenities, which are not the obligation of the Jets, and if we allow them to use tax-free bonds, what the Jets will be saving will go toward funding these amenities,” the chairman of the Empire State Development Corporation, Charles Gargano, told The New York Sun.

Those public amenities include helping to pay for a two-level structure above 33rd Street between Eleventh and Twelfth avenues to provide access to sports and exhibition events; a pedestrian bridge at 33rd Street to open access to the Hudson River Park and the ferry terminal at 39th Street, and a rebuilt portion along 30th Street of the High Line, the elevated railway tracks in Chelsea. The Jets also agreed to defray half of the cost of a proposed pedestrian bridge over West 39th Street.

The plan also outlines the physical project, including how the 2.2-millionsquare-foot glass-and-steel stadium, with its retractable roof, would be built on a steel and concrete platform above the Hudson Yards rail facility. In an area bounded by West 30th Street and West 33rd Street between Eleventh and Twelfth avenues, the 75,000-seat stadium could also be converted into a year-round, 180,000-square-foot convention center with 18,000 square feet of meeting rooms.

Below the stadium, which would have more than 200 luxury suites and 7,000 club suites, the Long Island Rail Road and MTA facilities would continue to operate.

The Jets would use the stadium for 17 days a year for football games, with 38 days for conventions, three days for plenary sessions, and two for national events, according to the plan. Taking into consideration the duration of events and other circumstances, the project would be used for 130 “event days” and 161 “transition days” a year, according to state calculations.
