"There are some very tough decisions that have to be made here, and no-one relishes making them," said Janet R Howard, chief executive of the Bureau of Governmental Research… "But to say that people should invest their money and invest their energies and put all their hope into rebuilding and then in a year we'll re-evaluate, that's no plan at all." In this sense, people's genuine fears of whether the city could cope with another flood, has combined with the general air of disquiet that New Orleans shouldn't be rebuilt at all in that location - and is impacting on the authorities' ability to impose clear guidance up on some core issues. Even though the practical discussion amongst recovery workers and political agents is slightly confused, it is still qualitively different to the line that Lord May took in his Anniversary Address to the Royal Society in 2005. 'It is conceivable,' he said, 'that the Gulf Coast of the US could be effectively uninhabitable by the end of century.' As a word of advice, he advocates that we stop building on floodplains and recognise 'that some areas should, in effect, be given up.'
