Miami's sea level rise bill is $4 billion by 2060. It won't keep every neighborhood dry.

Miami has to spend at least $3.8 billion in the next 40 years to keep the city dry from rising seas, according to a draft of the city’s long-awaited and newly released stormwater master plan.

1. Seems Too Low

This NYT link references a Swiss insurance giant estimating $23 trillion in global GDP damage by 2050.
It says most countries would experience 5% reductions in projected GDP due to shrinkage and mitigation costs.
Based on current GDP, that's already a trillion plus dollars for the US. Hard to believe Miami, given it's at sea level would be less than 0.4% of this damage, particularly since one estimate is 29 years and this estimate is 39 years.
Given time value of money, that trillion for the US is actually far too low.
I think it will be way more than $4 billion.

6. Understand that the City of Miami

Is actually fairly limited compared to what people think of as the miami area. There are dozens of cities that make up the Miami metro area

Miami Beach, for instance, has already set aside half billion dollars and already spent most of it ( I have personally been involved in about 50 million of that). And they have a long way to go.

So yeah, the number for the Miami metro area will likely be much higher. If it is even possible to save all of it. I don’t think it is. There will be parts that just become unusable

2. projections for sea level rise are rising.......

When this project started two years ago, planners wanted to know how to keep the city dry for the next 50 years. At the time, that meant building for the 18 to 30 inches of sea level rise expected by 2070.

Then the projections went up. Now, South Florida is planning to reach that level of sea rise by 2060.

4. Miami's rising seas will always percolate up through a limestone bedrock.

There's not much that we can do to stop Mother Nature. Throngs of local politicians and their families and friends will reap millions by sticking their little fingers in the dike.

7. The barrier island communities - Miami Bch, Palm Beach, FL Beach - are doomed. That's just reality.
