I think we have to have a Disaster Management Team of experts (who can understand the seriousness of such calamity but devoid of politicians)from various walks of life, which can suggest a plan to the government, get it sanctioned, have mock drills from time to time to ensure that the plan is implementable at the time of actual calamity. The Team could consist of volunteers from various strata of society, who could be trained and equipped, to meet the eventuality. There is no point looking towards the sky when we can do it ourselves. Mumbaikars, who have risen against all odds, can do it and stop depending on the bureaucracy / politicians to avoid lip sympathy and blame game.
