The Rochester and Buffalo metro regions plan to submit a joint bid in the highly competitive process to secure Amazon’s second headquarters. For the past month, the economic development arms of both cities had been putting together separate packages.

In a joint statement, Invest Buffalo Niagara and Greater Rochester Enterprise said it was apparent by linking efforts they could offer a proposal that is “both compelling and extremely competitive.”

Amazon said the new headquarters would bring up to 50,000 high-paying jobs over the next ten to 15 years. The Request for Proposals included a list of company preferences, including that the metropolitan area have more than 1 million people.

Both the Rochester and Buffalo regions have a little more than a million people each, which would have made them among the smallest cities applying. By combining, the agencies said the corridor will include a population of 2.2 million, a talented workforce, livable communities, and existing organizations that are excited to help entice Amazon to the area.

“This collaboration demonstrates the undeniable connectivity that already exists between our two great communities,” Erie County Executive Mark Poloncarz and Monroe County Executive Cheryl Dinolfo said in a joint statement. “In addition to several excellent site options and a low-cost operating environment, we believe that it is our people, highly-skilled workforce, world-class colleges and universities, and strong regional competency in radio-frequency identification, sustainable packaging, flight controls, drone technology, high-performace computing, software development, and data analytics that will help our proposal stand out.”

In addition to potentially eliminating concerns about lack of population, the collaboration also solves a potential dilemma for statewide and federal elected leaders. Few were choosing sides as the two cities, roughly an hour apart on the thruway planned to compete against each other.

Empire State Development has encouraged any region that qualified, including Rochester, Buffalo, Albany, and New York City to participate and has promised the state’s tax incentive package would be largely the same across the state. The two economic agencies have a week to finish the joint proposal before the October 19 response deadline.
