Gov: Upper Merion Board of Supervisors

The Upper Merion Board of Supervisors has denied a proposal for a massive data center complex in King of Prussia, Montgomery County. The project, proposed by developer Brian O'Neill, called for five sites totaling 4.6 million square feet, larger than Philadelphia International Airport. Supervisors cited insufficient detailed information as the reason for denying approval.

O'Neill stated he plans to appeal the decision, alleging that the board's vote was predetermined and that workshops to discuss project details were denied. He maintains that the project would have complied with all regulations and would have generated millions of dollars and supported approximately 15,000 jobs. Community members expressed happiness with the board's decision to reject the development.
