The city of Bengalooru had plenty of lakes earlier. Unfortunately due to lack of concern and unabashed greed, a lot of them are extinct now. Lakes are a very important aspect in the over all water management for a city like Bengalooru. (Some rivers were flowing through the city of Bangalore, I believe).

In the past I had shared images of useless pedestrian subways near Hammersmith. Instead the pedestrian refuges were so effective and popular that the subways became disused. Work is still on going, but notice how the ugly space occupying lesions have been surgically removed to make way for a more likeable streetscape.
