Considering the heavy flooding caused during the monsoon every year, the civic body has come up with a new policy to increase the size of roadside box drains. The implementation of this policy will help reduce flooding as water can travel faster through the drainage system and also because silt inside the drains will be easily removed, which currently doesn't happen.

The roadside storm water drains are constructed adjacent to the pedestrian footpaths but are two feet below in the western and eastern suburbs. The drains are generally proportionate to the road width, eg: for a road width of 60 feet, the width of the drains is 0.6metres, and for a road width of 90 feet, the width of the drains is 0.9metre. However according to the new policy, for roads of 90 feet and below the width of drains will be 0.9 metre standard and roads above 90 feet will be 1.2 metres.
