Trump Entertainment Resorts Inc. plans to close one of its two Atlantic City casinos in September, putting about 1,000 people out of work in the seaside New Jersey resort town.

Employees were notified today that the company is reviewing options for the Trump Plaza Hotel & Casino and plans to shutter it as soon as Sept. 16, according to a statement from the company. That would leave the Atlantic City-based company with one property, the Trump Taj Mahal, in the market.

The East Coast gambling hub is withering amid growing regional competition. The Atlantic Club closed in January, Caesars Entertainment Corp. plans to shut the Showboat on Aug. 31, and Revel, the $2.4 billion mirrored-glass casino that was supposed to usher in a resurgence for the city, is searching for a buyer in bankruptcy.

If all the properties close, as many as 8,000 people will be unemployed, Assemblyman Vincent Mazzeo, a Democrat who represents Atlantic City in the state legislature, said on July 12. The Trump Plaza has 1,009 employees, according to the New Jersey Division of Gaming Enforcement website.

“The big issue for this region is that you’ll have 6,000 to 8,000 people who will now be unemployed,” Mazzeo said in an interview. “That’s going to have a devastating effect on our economy and on this region.”
