I never heard floods in Vizag, except the low lying areas like gnanapuram..
Most of the areas in Vizag are above sea level and has red soil.
Inka cyclones antara..we can't stop them, may be construction can be solid so that it can be handled.
20 years ago rushikonda area used to have sarega thotalu, but not any more.
Ex: new IT tower can handle 240km/h intensity cyclone.
