What's the factor of damage of heavy rain in Seocho?
In this summer in Korea, Heavy rain was very serious problem and especially in Seocho / Gangnam, this situation causes so many problems and it made to expose to weakness of this area. There was landslide and flood also this problems cause to another problems like cutting the electricity and water, road interdiction and so on. So why this kind of situation was happen only in Seocho ? (actually Gwanhwamun has similar situation but worst place was Seocho and Gwanghwamun has topographical issue so I except to write about this area.)
As you know, Seocho is most expensive area in Korea so there is many profit about property. So so many construction company try to make big buildings in this area and the gorverment accept all this proposal from construction company without consideration. How the construction company build a apartment? They cut the all forest and mountain and make thier beautiful buildings. Actually this kind of story sounds very boring but its very important to people's life. Because they destroied so many green spaces in Seocho also they digging the to many spaces, Seocho's ground is very weak which means the ground can't shore up from land disaster. And also the ground can't absorb a lots of water because there are not enough trees so landslide happend because of this factors.
So, the gorverment should make well-organized city plan for Seocho area to prevent all kind of heavy rain disaster.
