HARRISBURG - The Pennsylvania Gaming Control Board today voted unanimously to extend Foxwoods Casino's license only if it sticks to its original plans to build a substantial slots parlor on the Delaware River in South Philadelphia.

The vote by the seven-member board came after Chairman Gregory Fajt recommended just that action at the end of an hour of testimony from Foxwoods officials.

The extension lasts until May 2011.

The board's staff recommended that the Foxwoods developers deliver a design in three months and financing details in six months.

"We do not want to hear that there are other sites that you want to look at," Fajt said before the voice vote. "We expect that facility to be a substantially similar facility to what we granted the license on [in 2006]. I cannot be any more emphatic on making those comments."

Fajt said any discussion to relocating would be "a fool's errand."

"We expect you to move and move quickly or we'll yank the license," Fajt said.

Opponents of the casino who lined the back of the hearing room erupted into chants of, "Pull the plug! Pull the plug!"

F. Warren Jacoby, a lawyer for the Foxwoods partnership, said investors already have spent $160 million on buying the land on Columbus Avenue, acquiring a license and development fees.

The casino developers had wanted to open in the old Strawbridge & Clothier department store at 801 Market Street, but have not been able to get a lease because of a dispute between the building's owners.

If the project has to stay on the waterfront in South Philadelphia, the investors behind the casino will have to come up with new financing and a new design, testified Brian Ford, an executive for a partnership representing some of the partners.

What was envisioned in 2006, when Foxwoods won one of two slots licenses for Philadelphia, would not work in recession-battered 2009, industry observers say.

The original plan was to build a $670-million, mega-casino with more than 700,000 square feet of gaming space, plus an adjacent hotel and other amenities.

But such a plan would be difficult to finance given the recession, drying up of credit and drop in gaming revenue, industry experts say.
