Florida boats and bridges

It never occurred to me that if the sea level in Florida is rising, that means that the bridge clearances will be diminishing.

"Relative sea levels in South Florida are roughly four inches higher now than in 1992."

The idea of the prisoner's dilemma is an interesting point.

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Re: Florida boats and bridges

its been so dry here - water levels in most rivers are down, so the short term , higher bridge clearances.

Re: Florida boats and bridges

I had no idea that there was so much action around this problem in FL. We toured all the normal retirement spots last year.

One realtor said that right now the pessimists are selling to the optimists and that the majority of people are optimists.

Builders are building their buildings higher but the towns have no money to work on the infrastructure. So your million dollar condo will be fine but the road to get to it will be under a foot of water for a month.

Right now it seems to be holding steady but since people are herd animals I wonder what it will take for the tide to turn so to speak.

Maybe one insurance company pulling out of the market, then boom.

It's like a game of musical chairs. Some day the water level will be 3 feet higher and billions of dollars of land will be lost. In the meantime, their is a lot of money to be made on prime waterfront property. The only question is who gets stuck holding the bag and when.

For us sailors, it is an issue as FL is such a great place to sail.

Re: Florida boats and bridges

I guess then one should keep their boat at marina with floating docks in the future. There are problems with king tides in South Florida - times of the year when the tides are higher than usual - is you get heavy rain and/or a strong easterly wind - water gets pushed up inland - floods streets in Ft Lauderdale and Miami, I assume this will only get worse in the future, its not that the water is going to remain high all the time its just that when there is a storm or high tides - the damage is going to be worse.

I am in Orlando - if the high tide gets here , we all will be up sh*t creek without a paddle.

Rubbish... The recently released Florida Sea Grant update study to their 2009 report shows an average sea-level increase of just over 5 cm from 1990 to the present. They are projecting an increase of 50 cm by 2100 if the current rate of increase were to remain unchanged. Most, if not all, bridges in Florida will need replacement before then.

The Sky "ain't" quite falling yet...

"It is not so much for its beauty that the sea makes a claim upon men's hearts, as for that subtle something, that quality of air, that emanation from the waves, that so wonderfully renews a weary spirit."

I will finish the report but this is a quote:

Studies conducted since 2007 indicate that
such contributions are already becoming significant
and will most likely increase, causing
sea-level rise by 2100 to range between 0.5
meter (about 20 inches) to more than a meter
(more than 3 feet). Much has yet to be learned
before sea level can be projected with greater
precision and certainty, but the differences are
largely a matter of when, not whether, economically
and ecologically critical levels will be
reached.

Since mortgages are typically 30 years and only a foot would be a disaster and insurance and banking people are very conservative my only question is when the pessimists will outnumber the optimists.

Not today of course but when it happens I suspect it will be fast. It will be like a run on a bank. The bank is good until everybody knows someone who has taken their money out.

Re: Florida boats and bridges

David-
"Florida" can be a very different place, depending on whether you have Jax or Tampa or the panhandle or Miami in mind. It really is many very different places. Thw worst of global warming may be the impact on Miami/Ft/Laud, where the coastal road (A1A) already floods out regularly. Where the ground water, rising with the rising sea level and saltwater incursions, prevents rain from draining, and the flood control canals have to be pumped uphill to function. Assuming the seawalls, gates, and power hold up during storms. Where real estate has been vastly oversold to shortsighted retirees, who didn't notice the roads are well over capacity and there's no real public transportation, for when they really do need to stop driving.
The wheel turns...and cheap land and no taxes (or services) could make other places better considerations. SE Florida has had more people move OUT in recent years, than retirees moving IN. The growth numbers are only supported by "aliens" moving into Florida from outside the US, it turns out.
And while there are a solid number of people looking to do something, it is not going to be pretty trying to build an infrastructure, modify the one that hardly exists, and still maintain no income tax--which is what attracted so many Yankees in the first place.
Besides, you get better bridge clearance with the Sunshine, in Tampa/St. Pete. Still has the roads over capacity, but at least they're a little further above sea level. And closer to the continental United States.(G)
