A controversial plan to bring a new $1.2 billion arena and entertainment venue to state-owned Belmont Park will now include a $105 million full-service stop on the Long Island Railroad, Gov. Andrew Cuomo announced Monday.

The station serving Belmont, NY, is a huge score for the New York Islanders arena project and will be situated between the Queens Village and Bellerose stations on the LIRR’s Main Line, just east of the Cross Island Parkway.

A press release put out by the governor’s office claimed it will cost the arena developers – a partnership that includes the owners of both the Islanders and New York Mets — $97 million of the estimated $105 million price tag.

However, state officials later clarified that the developers are only paying $30 million up front with the remaining $67 million to be covered by a no-interest, multidecade state loan. The state will pick up the remaining $8 million.

The news didn’t sit well with project opponents.

“Obviously the State of New York wants to play hide the puck, and pretend that arena developers are paying for a massive transportation project instead of the taxpayers and commuters, and they buried that actual fact in the fine print. That is a disrespect, and cardinal breach of public trust,” said Tammie S. Williams of the Belmont Park Community Coalition.

There’s a long history between the developers and Cuomo’s campaign war chest.

Sterling Equities, the development arm of Mets owners Fred and Jeff Wilpon, gave Cuomo $65,000 in January 2017 – less than a year before the company and the rest of the Islanders group won a state bid to develop Belmont.

Moreover, members of Islanders’ co-owner Scott Malkin’s family have given Cuomo at least $205,000 since 2017.

Cuomo’s office estimates the project will generate $725 million annually, creating 10,000 construction jobs as well as 3,200 other jobs.

The project still requires various government approvals, including the Public Authorities Control Board.

“Political donations have no influence on government actions, period,” Cuomo spokesman Jason Conwall bit back.

“Through this public-private partnership, the developer will repay New York State for 92% of the cost of a new LIRR station in Elmont that will provide 24-7 service to an area that has long-needed it, alleviating congestion and cutting commutes for thousands of New Yorkers. This ESD financing package provides a unique solution that applies private funding to create a permanent, public, MTA station, showing the creativity necessary to revitalize the system,” Empire State Development spokesman Jack Sterne told The Post.
