Images of Bengaluru, deluged with knee-high water, people fishing on the streets, boats out to rescue stranded commuters, turned national attention late last month to India's Silicon Valley in utter shamble.

More than 100 buildings have been razed this week; another 1,100 have been identified for full or partial deletion from the city's maps in the next four months.
