Let’s Know about “Flood in Katsushika City”

Katsushika City is the district of low-lying area surrounded by the four rivers of “Arakawa”,“Edogawa”, “Nakagawa” and “Ayase”. About half of Katsushika is located in the area below sea level.
Katsushika City is making a strong community against flood damages by various methods. On the other hand, the flood risk is increasing due to the climate change and extreme weather in recent years.
Let’s study about flood damage that might occur in Katsushika City, and we should usually provide against all conceivable emergency .


Flood Damage that Can Occur in Katsushika City
River Flood: Water of a river overflow its bank in the city.

【When to Be Careful】
Heavy Rain
 ●River bank can collapse in the upper reach, etc. of a river.
Typhoon

●River water can overflow its bank due to a heavy rain and a storm surge (a phenomenon that causes a rise in sea level and water from the sea flow into the land).

※Normally, heavy rains and typhoons do not have such a high risk of causing damage, but special attention is required when unprecedented levels of heavy rains and typhoons hit the area.

 ●We have time to evacuate because risks of disasters can be predicted in advance.
 ●Once a city is flooded, it takes several weeks until the flood water recedes.

How to evacuate

Evacuate to a Safer Place as soon as Possible

●Evacuate to an area where you can avoid flood damage (get away from a dangerous place and evacuate to a safer one) within Katsushika City or in neighboring cities (Ichikawa City and Matsudo City of Chiba Pref., Taito City, Sumida City and Arakawa City, etc.).

Evacuate to a Tall Building if Failing to Escape
