They feared that the public services in the city — the subways, the schools and the neighborhoods — would be overtaken by Amazon.

Amazon, whose founder Jeff Bezos owns The Washington Post, had yet to lease or purchase office space for the New York City project, the paper reported Friday.

What may have been the final straw for Amazon was a recent decision by the state Senate to add one of the most vocal opponents of the project to a little-known state board — the Public Authorities Control Board.

The Senate appointed Sen. Mike Gianaris, D-Queens, to the board, which would have to have approved at least some of the public aid for the project.

Critics said the deal was brokered without public knowledge.

“Today’s behavior by Amazon shows why they would have been a bad partner for New York in any event,” Gianaris said in a statement.

“Rather than seriously engage with the community they proposed to profoundly change, Amazon continued its effort to shakedown governments to get its way.”

 Cuomo put the blame squarely on the Senate for scuttling the deal.

“A small group of politicians put their own narrow political interests above their community — which poll after poll showed overwhelmingly supported bringing Amazon to Long Island City — the state’s economic future and the best interests of the people of this state,” he said in a statement.

“The New York State Senate has done tremendous damage. They should be held accountable for this lost economic opportunity.”

But Cuomo said the reasons Amazon wanted to come to New York — its talent pool, education system and diversity — will sustain even without the company.

 “We won’t be deterred as we continue to attract world class business to communities across New York state.”

Cuomo and New York City Mayor Bill de Blasio helped broker the deal and warned for weeks that local opposition could jeopardize it.

Cuomo’s office said the $3 billion in public subsidies would be small compared to the estimated $27 billion in economic activity and jobs the company would bring to the city and metropolitan area, an estimate culled from a state-financed report.

De Blasio on Thursday knocked Amazon for the decision.

“You have to be tough to make it in New York City,” he said in a statement. “We gave Amazon the opportunity to be a good neighbor and do business in the greatest city in the world. Instead of working with the community, Amazon threw away that opportunity.”

Republicans in New York blamed Democrats for Amazon’s decision. They had hoped Amazon would led to job opportunities for the whole region, including the Hudson Valley and Long Island.

“From the start, the Senate Democrats have politicized and poisoned this process just so they could avoid the wrath of the extreme left wing of their party,” said Senate Republican Leader John Flanagan, R-Suffolk County.
