SPRINGFIELD, Mass. (AP) -- Casino giant MGM Resorts International is unveiling its plans for an $800 million casino in downtown Springfield.

The company announced in an elaborate news conference at the MassMutual Convention Center on Wednesday that the entertainment complex would be built on 10 acres of land heavily damaged by a tornado in June 2011.

The proposal includes a 250-room hotel, 89,000 square feet of gambling space and 70,000 square feet of retail and restaurant space. Company officials said it would provide 2,000 construction jobs as well as thousands of permanent jobs and millions of dollars in tax revenue for the city.

MGM has already submitted a $400,000K non-refundable application fee to the Massachusetts Gaming Commission. MGM Chairman Jim Murren said the presentation is "a significant demonstration of our desire to partner with Springfield."

The number of people visiting the Las Vegas valley in June is up compared to the same time last year, but the amount of money casinos won from gamblers was down.

The Las Vegas Convention and Visitors Authority says about 3.4 million visitors came to Las Vegas in June. That is up 2.1 percent over the same month last year. There were more hotel rooms available for those visitors. However, occupancy rates citywide remained at about 88 percent.

The Nevada Gaming Control Board says the money Clark County casinos won from gamblers was down in June by almost 8 percent. Strip casinos saw a nearly 5 percent drop over the same time last year. The Boulder Strip saw a 23 percent drop.

Casinos in Northern Nevada had a much better month. Casinos in Reno and South Lake Tahoe saw increases in what they won from gamblers.

A judge began hearing arguments Monday on whether to repair Harmon Tower at CityCenter or to bring the building down.

The hearing focused on Perini Construction's proposed repair plans for the buildings. Lawyers for MGM Resorts questioned a representative from an engineering firm hired by Perini who inspected the tower.

Engineers with John A. Martin and Associates said they found both design and structural problems with the building. The firm’s president told the court he did not agree with reports by other inspectors that Harmon Tower is too structurally weak to stay standing.

According to MGM Resorts, a co-owner of the tower, the building needs to come down because it is not structurally sound. Perini Construction, the general contractor on the project, has insisted that the building can be repaired.
