A new casino could be coming to Long Island, with the Shinnecock Indian Nation set to announce plans for one on its Southampton land.

Details of the plan are set to be unveiled Wednesday, with the tribe partnering with Hard Rock Entertainment and a development company to build the casino.

Local officials, along with civic leaders, have voiced their concerns over the yet-to-be-seen plan, especially since they have no say on what the Shinnecock Nation can build.

Southampton Town Supervisor Jay Schneiderman says a full-scale casino would create a traffic nightmare along an already jammed up Montauk Highway and have a negative impact on the Shinnecock estuary.

"It's hard to imagine a worse location from a traffic standpoint and an environmental standpoint, and I think they know that too," says Schneiderman.

Schneiderman believes the Shinnecocks may be angling for a better location for the casino, an operation its press release says will be much like Jake's 58 in Islandia with video lottery terminals and high-stakes bingo gaming.

The Shinnecock Nation was federally recognized as a tribe in 2010 and has made several attempts to open a casino.
