You know - looking at the last three posts of yours, Macdoc - you do know that Sandy and Katrina were entirely different storms, which hit the US about a thousand miles apart, don't you?
That is just about the ultimate bit of stupidity you've ever posted. It surely leaves your understanding of the change in storms and the fields of storm influence as completely missing.
FIrst a cyclonic storm is a cyclonic storm.....Katrina was a high power cyclonic storm known to be relatively common in the regions.
Sandy is also a normal cyclonic storm that was steered by a high pressure zone that was a product of the change in the jet stream and enhanced by high water termperatures further north than historically normal.
The New York regions has had storms like this before and was over due - it was a wake up call .....something that I had posted about a number of times over the last 10 years.
Is NYC Way Overdue For A Hurricane?

Sandy's impact is already being triaged as to what will be rebuilt and what will not be...I make no suggestions ....I make observations.
In the two years since Hurricane Sandy flooded the East Coast, New York City has navigated a difficult recovery process. Communities devastated by the storm, including Breezy Point and Sea Gate, have struggled to rebuild, while in Staten Island, residents of some of the most damaged areas have decided to sell their homes to the government and never return. In Ocean Breeze, Oakwood Beach, and Graham Beach, the Governor's Office For Storm Recovery is now purchasing houses, tearing them down, and returning the land to nature.
Choosing a "managed retreat" from the water has actually provided some relief for residents. "It's a bittersweet feeling, but I know that no one else will have to go through this kind of storm," said Joe Herrnkind, who lived in Ocean Breeze for 16 years. "The house wasn't a home anymore, it was a prison."

Katrina was warned about, was gamed a year ahead by the local disaster

Nov 22, 2005 - For years, Ivor van Heerden, a hurricane expert at Louisiana State University, saw a tragedy coming. Since 2001, he and colleagues had been generating computer models of how a major storm could inundate New Orleans. ... In these interviews, conducted both 10 months before and then soon ..
New Orleans remains at high risk as it is sinking and sea level is rising and the Gulf temps are rising. Fortunately the Atlantic and Gulf hurricane season have been mild ( the relationship with El Nino is not clearly unstood as to mechanism )
What I gather from your posts are ...
You know nothing of the global and changing nature of AGW influenced extreme weather ....tropical and sub tropical storm intensities are moving into mid-latitudes both coastal and inland in UK, Europe and North America due to AGW.
That's my interest and the response of the cities affected
You know nothing of the many thousands of posts I've made on RDF and here.
What I'm looking for in this thread is to move into the discussion of policy reponses to the increased risk AGW poses by way of sea level rises and storm intensity increases.
The Netherlands has a clear path ahead and has allocated the funds.
The US , as mentioned is a patchwork tho the New York response to Sandy is heartening and appropriate

Chesapeake Bay is another very vulnerable area both biome and human habitation
Sea level is rising rapidly around the Chesapeake Bay. Faster actually, than nearly any other place on the East Coast of North America, and only a few spots along the Gulf Coast are recording a faster rate. The reason has been suspected for quite a while, but now a new study published in the journal of the Geological Society of America has confirmed the cause, and the news is not good. The paper is titled Pleistocene Sea Levels in The Chesapeake Bay Region and Their Implications for the Next Century.

Plus it is also sinking.
Ongoing GIA-driven subsidence in the Chesapeake Bay region challenges a region already threatened by sea-level rise. At the Blackwater National Wildlife Refuge, we use rate consistency to predict ~0.16 m of subsidence for the region in the twenty-first century (using twentieth-century values from Boon and others [2010] that presumably include the effects of groundwater withdrawal). The likely range of average global sea-level rise for the twenty-first century is 0.33–0.82 m, based on a non-aggressive climate mitigation policy (IPCC, 2013).

The US responded rather well when poor agriculture practices created the conditions for the Dust Bowl.
The effort to armor or abandon vulnerable areas of the coast line will require a coordinated national effort as is happening in the Netherlands and as is being debated in the UK as to what is appropriate.
