Town development plan where evacuation lives can be carried out even when rivers are flooded. National government and capital to prepare for maintenance. September 10, 5:05
When a large-scale inundation occurs in the Arakawa and Edogawa streams in the Tokyo metropolitan area, it is feared that the areas along the river will not be flooded for a while.
The Ministry of Land, Infrastructure and Transport and the Tokyo Metropolitan Government will decide on a model district and develop it, considering a town development plan for living the minimum evacuation life, such as connecting floors that are not flooded to each other with a passageway. It was
According to the Ministry of Land, Infrastructure, Transport and Tourism, if the embankment of Tokyo's Arakawa broke, inundation would continue for two weeks or more, mainly in the zero-meter zone above the sea level in Koto's 5 wards.
Although there are concerns about the isolation of residents, the Ministry of Land, Infrastructure, Transport and Tourism and the Tokyo Metropolitan Government have come up with a new town development plan so that people can live at a minimum level of evacuation even if flooding continues.
Specifically, by connecting passages between floors that are not flooded between buildings to allow access to the outside of the flooded area without passing through the flooded land, or covering the surrounding land with the development of the embankment. We plan to raise it and extend the depth of the embankment to the city area.
Both of these plans require a lot of budget and time, but the Ministry of Land, Infrastructure, Transport and Tourism and the Tokyo Metropolitan Government have decided to develop a policy plan within the year and decide and develop a model area.
The Ministry of Land, Infrastructure, Transport and Tourism says, "In addition to "wide area evacuation", where people evacuate outside the flooded area in advance, we would like to put effort into creating a city where people can live their minimum lives within the flooded area."
