Using more than 500 flood simulations, scientists were able to calculate roughly how much cash NYC should expect to spend on flooding every year, plus how much the city will lose over the next century if it does absolutely nothing. The results aren’t surprising but no less ugly: Another century floor would cost NYC $2.2 billion. A 1,000 year flood would cost NYC $25 billion.
A barrier stretching from Sandy Hook to the tip of the Rockaways, for example, would protect Lower Manhattan. It could also protect the Jersey Bayshore.
This is exactly why flood mitigation shouldn’t be looked at municipality by municipality – it should be looked at a region and interstate level.
It is estimated that blocking off the entire harbor would cost between $11 – $24 billion. I think splitting the cost on this makes way more sense than individually trying to fight this.
