Living on islands in "hurricane alley" may will become more dangerous as we progress toward the storms of our grandchildren.
Local energy farms with some interconnectability seem preferable to a centralized energy source that is reliant on vulnerable transmission lines. Transportation of energy, food, water, people, and goods, will become increasingly difficult to maintain in the face of increasing storms, so each local needs to build upon it's self sufficiency.
Communities near the shoreline need robust ports, and redundant roads, bridges and other linkages to nearby communities. Land locked communities need networks of interconnectivity so that if one pathway is destroyed, others are still available.
I'm not convinced that this would require more infrastructural expense than building large robust facilities, which will still be subject to destruction or failure when the perfect storm hits.
The growth of huge mega-cities seems to be the direction that many of the less affluent regions have evolved. Staying away from this trend would be better for everyone involved, but without the incentive of a vibrant, self sufficient, small community, with access to work and some hope of sustainability, the poor will continue to crowd into slums that are probably the least likely to stand when the SHTF.
Rather than spending on large, hopefully resilient cities, an emphasis on smaller, interconnected communities, that together can weather whatever storms are on the horizon, might be a better way forward.

Without debt forgiveness PR has little to look forward to. It's not fair to this generation to punish them for the sins of their fathers, and their fathers were probably no more than victims of our fathers greed.
