The speaker of the City Council, Gifford Miller, said in his “State of the City” speech on February 24 that he would apply to change the zoning on the Manhattan site the Jets want to use for a football stadium. The change would make it easier for developers other than the Jets to build on the site by allowing higher-density apartment buildings or offices there.

Nearly a month later, Mr. Miller has yet to take any public action on the rezoning.

The 23-member Land Use Committee that must approve the application has met several times, but the item has been conspicuously absent from the agenda. Yesterday, Mr. Miller’s chief spokesman, Stephen Sigmund, said the application was still being prepared. He said the Bloomberg administration was lobbying committee members to vote down the measure, but that the speaker was confident it would pass.

Late last week, Anthony Weiner, who represents parts of Brooklyn and Queens in Congress, called on Mr. Miller to take action on the matter. Mr. Weiner, who, like Mr. Miller, is seeking the Democratic Party nomination to challenge Mayor Bloomberg, accused the council of helping accelerate the mayor’s stadium plan by agreeing to zoning changes in the area around the stadium site earlier this year.

Mr. Miller’s push for zoning changes is just one of several strategies he has for blocking a project that Mr. Bloomberg has put much of his political stock in. The council is also trying to prevent Mr. Bloomberg from paying the city’s portion of the stadium without its approval. It is holding a hearing on that issue this week.

Filing an application to rezone the site could give Mr. Miller another way to attack the mayor as the campaign season moves forward.

“Everything related to the stadium at this point is about symbolic politics,” a professor at Columbia University’s School of International & Public Affairs, Steven Cohen, said yesterday. “All of the stadium opponents are trying to paint Mayor Bloomberg as someone who cares more about the people who sit in luxury boxes at the Jets games than about the need to fill potholes in Brooklyn.”

The City Planning Commission, which handles zoning, includes several members appointed by the stadium’s biggest proponent, Mr. Bloomberg.

“It goes nowhere because it needs the support of the City Planning Commission and City Planning Commission is the mayor,” Council Member Tony Avella, a stadium supporter, said. Mr. Avella said it does not make sense to add more housing or offices to the area.

In January, the council and the mayor brokered a deal to rezone a 59-block area around the stadium site to clear the way for nearly 14,000 units of housing and 24 million square-feet of office space. The goal of that deal is to convert an area marked by parking lots and industrial warehouses into a thriving residential and commercial neighborhood. One of the caveats of the agreement, however, is that the $1.4 billion Sports & Convention Center is excluded and no city funds can go toward any of its infrastructure.

With the larger rezoning behind him, Mr. Miller is now attempting to make changes to the stadium site itself that will make it more attractive to another developer. The Bloomberg camp has repeatedly said the area cannot handle more housing and that the stadium will be a draw for the neighborhood and a boost for the economy.

A spokeswoman for the city Planning Department, Rachaele Raynoff, reiterated the mayor’s earlier statement, saying the city would review any qualified application. All applications, she said, are treated the same.
