Relocation of the United Nations to an Outer Borough
Moving the United Nations to an outer borough should be considered. This proposal could combat Manhattan traffic congestion, increase tax revenue, and generate tourism.
Every time there is a UN meeting, midtown gets locked down and there are terrible traffic jams. By moving an important center of power to an outer borough, the new location could benefit from additional tourism (the Community Boards must have power to decide if they want this and what they would trade for it).
What to do with an empty 42nd street? (Yes, the UN would be dismantled.) The area would be opened up for taxable development, increasing revenue for the city.
One specific option to consider is to replace the Casino with the UN, which would bring better jobs in that area. The proximity to the airport would allow dignitaries to get there without closing traffic.
Under any of these proposals New York City would still have the UN, it would just be in another borough.
I hope this idea sparks discussion.
