Here's the quick read on why the Pennsylvania Gaming Control Board chose Live! Hotel & Casino in South Philadelphia for Philadelphia's second casino, based on a document just posted on the board's website.

The pitch by Live's backers - Cordish Cos. and Greenwood Gaming & Entertainment Inc. - that they could tap into the millions of annual visitors to sporting events and concerts at the stadium complex was convincing.

"The board finds the synergy between gambling and entertainment at a casino with the sports and concert enthusiast visiting the more than 400 stadium area events per year presents an opportunity for marketing the stadium/casino area into a 365-day-per-year attraction with minimal negative impact on the surrounding areas," the document, known as an adjudication, said.

By contrast, the board was not convinced that the proposed Casino Revolution, at Front Street and Packer Avenue, would generate the same level of crossover traffic.

Furthermore, board members feared that presence of truck traffic in the area around the proposed Casino Revolution would "pose a substantial obstacle for patron visitation."

As to the Center City sites, the board agreed that Market8 and The Provence had the potential to spur other development in their immediate areas, but the board also noticed that a resurgence in Center City is already happening.

"In other words, the board does not believe that the transformation of Center City is dependent on the board awarding a license there," the filing said.

The biggest reason to reject the Center City sites might have been this: the Board has heard repeatedly during testimony that casino patrons typically arrive by personal auto, a means of transportation not always conducive to center city locations."
