Q&A summary

Contents of question Answer
[About disaster countermeasures]
I would like to ask about the damage in the city from the previous typhoon, and future issues and countermeasures based on that.

・We were hit by a series of large typhoons this autumn.
・Typhoon No. 15 on September 9th, this typhoon was more affected by the wind than the rain, and several trees fell in the city. In Chiba Prefecture in particular, fallen trees caused extensive damage, causing a large-scale blackout that lasted for a long period of time.
・Typhoon No. 19 on October 12 caused record-breaking heavy rains in the Kanto, Koshin, and Tohoku regions.
・In the city, the Tama River exceeded the flood warning level, and landslides occurred in several places on private land, but fortunately there were no casualties. However, there was a risk of flooding of the Daimaru Yato River, a tributary of the Tama River, so we requested the Keihin River Office of the Ministry of Land, Infrastructure, Transport and Tourism to dispatch a large drainage pump truck to close the floodgates and carry out drainage work.
・A super embankment has been built in Inagi, and the embankment of the Tama River itself is difficult to collapse. However, the super embankment project fell through due to the scrutiny of the project during the Democratic Party of Japan administration. As a result, one location on the north side of Yanoguchi Station has not been developed, and the policy is to work on the development using a method that replaces the super embankment.
・We will make use of this disaster as a lesson for disaster prevention measures, but it is difficult to completely stop the damage caused by the disaster. I would like to request that the equipment be deployed in the Tama River basin.

I would like to ask about the challenges and responses to evacuation. ・During Typhoon No. 19, the city issued an evacuation advisory, and about 3,500 people were evacuated to evacuation shelters at the peak, making it the first large-scale evacuation in the city.
・In the event of storm and flood damage like this time, there is a risk of flooding along the Tama River, and it is not possible to open it as an evacuation center. I know there was some confusion in the department.
・More than 3,000 people were evacuated, and it was the first time for the city to evacuate, but we would like to make use of the lessons learned from this disaster in Inagi City's measures against storm and flood damage. A revised version of the disaster prevention map is currently being prepared, and will be distributed to all households within this fiscal year. The contents will be enhanced and will be published in a booklet version. When you receive it, please read it carefully and use it to prepare for disaster prevention.
In Hino City, many citizens moved by car during the evacuation, causing problems such as traffic jams. Does Inagi City have any plans to use private facilities, such as those of Tokyo Verdy and the Giants, as evacuation centers? ・As a general rule, when evacuating, we ask that you move on foot and do not come by car. Evacuation centers are not designated or restricted by the place where you live, and you can evacuate to any evacuation center. Please walk to the nearest evacuation shelter.
・At this time, we are not considering expanding the number of evacuation centers to include private facilities.
[Maintenance of Misawa River]
What is the maintenance plan for the Misawa River near Wakabadai? Also, is the plan for widening the Tsurukawa Highway progressing?
・For the undeveloped section in the upper reaches of the Misawa River, planning itself has not yet been made.
・We have submitted a request for early maintenance to the Tokyo Metropolitan Government, but it has not been realized.
・However, as to whether the undeveloped section is in a dangerous situation, it is not a dangerous situation, so I think that it is not a high priority for the Tokyo Metropolitan Government.
・Regarding the expansion of the Tsurukawa Highway, construction will proceed according to the plan of the metropolitan government.
[About the firefighting system]
Will the city continue to carry out its own firefighting? Why don't you entrust it to the Tokyo Fire Department?
・In the city, it is a policy to maintain independent firefighting in the future.
・One of the advantages of organizing your own firefighting is that the initial response is quick. Although they cannot carry large equipment such as helicopters, they have concluded support agreements with the Tokyo Fire Department and other related organizations in the event of a disaster, so they can receive support when necessary.
・Also, we have our own rescue team, so when the typhoon increased the danger of overtopping the Daimaru Yato River, city construction department staff and the fire department rescue team worked together to rescue the swollen Tama River. Fortunately, the area was spared flood damage by operating to close the sluice gates installed along the embankment.
・In addition, regarding the way firefighting should be, the mayor does not arbitrarily decide that it should be a single firefighting. We are making decisions based on consideration while doing so.
[About support for residents' associations]
I heard that Tama City made an ordinance to support residents' associations. Even in Inagi, I would like to see generous support for the self-reliant management of residents' associations.
・We think that existence of residents' association taking mutual assistance is very important.
・In recent years, the rate of participation in residents' associations has been declining, and this itself is seen as an issue. It is possible.
・The city is trying to spread the word about joining residents' associations, such as distributing leaflets to new residents.
・As a support measure, we spare no effort in providing support for "mutual assistance" in the voluntary activities of organizations, but I think that support that falls under "public assistance" has a different meaning.
[About road maintenance plans]
Are there plans to review the progress of the maintenance plan for the urban planning road "Sakahama Hirao Line" and the bus route after opening? Also, will express trains on the Keio Sagamihara Line stop?

・As for the Sakahama-Hirao Line, construction was delayed due to a bidding failure from the Tokyo Metropolitan Government, but the entire section from the intersection at the entrance of Wakabadai to the fire station in Hirao is scheduled to open in late November.
・About bus route, we hear that private bus company side plans to extend. As for the i-Bus, there are no plans at this time, as there is a risk that private buses will withdraw if they compete with private-sector buses.
・The suspension of express trains on the Keio Sagamihara Line has been a long-standing issue for Inagi City, but among the stations where express trains stop on the Sagamihara Line, Nagayama Station has the lowest number of passengers, with 40,000 people. On the other hand, the number of passengers at Inagi Station is 20,000. I think that realization is difficult, but I would like to continue to make requests in the future.
