Protecting At-Risk Cities From Rising Seas

Hugh Pickens writes "BBC reports that with about 10 million people in England and Wales living in flood risk areas, rising sea levels and more storms could mean that parts of at-risk cities will need to be surrendered to protect homes and businesses, and that 'radical thinking' is needed to develop sea defenses that can cope with the future threats. 'If we act now, we can adapt in such a way that will prevent mass disruption and allow coastal communities to continue to prosper,' says Ruth Reed, President of the Royal Institute of British Architects. 'But the key word is "now."' Changing sea levels is not a new phenomenon. In the Netherlands, for example, with 40% of its surface under sea level, water management and water defense have been practiced since time immemorial; creating mounds and dykes, windmills, canals with locks and sluices, the Delta Works and the Afsluitdijk, all to keep the water out. Similar solutions to protect British cities are based on three themes (PDF): moving 'critical infrastructure' and housing to safer ground, allowing the water into parts of the city; building city-wide sea defenses to ensure water does not enter the existing urban area; and extending the existing coastline and building out onto the water (using stilts, floating structures and/or land reclamation)."

Live in a house boat. They float. An chicks dig house boats.

Well, telling them doesn't work

A lot of houses in Britain have been built on flood plains.

Even though they are clearly marked on the maps, and (presumably) are discovered in property searches, people still buy these places. Yet when the inevitable happens - for rain is a fact of life in England, they whine and moan about "our house has flooded ... you gotta HELP us!" Better still, a lot of river-side properties are very desirable and attract huge premiums. The buyers seem not to associate having a large body of moving water, passing by the bottom of the gardens to their million-pound houses, with any sort of risk, at all.

All I would suggest is huge .... massive .... crippling ... increases in home insurance premiums to both alert buyers to the dangers and also to make them pay the going rate for repairs and renovations - rather than being subsidised by all the sensible people. Just like happens with car insurance.
