This publication does not take into account inland ﬂooding (particularly ﬂooding from drainage and sewer
overﬂows) or the backwater eﬀect (tributaries ﬂowing backwards due to higher water levels in the main river).
Due to the fact that rainfalls are very complex, such as heavy downpours over a short period of time or large
amounts of rainfall over a period of a few days, it is possible for ﬂood depths to diﬀer from predicted depths
or for ﬂooding in areas that weren t expected to be ﬂooded.

How to Use the Hazard Map

1 Anticipating the Highest Amount of Rainfall
During the Reiwa 1 East Japan Typhoon (Typhoon Hagibis [No. 19], 2019), theShinano River reached the highest water levels in recorded history.
This hazard map was edited with the highest anticipated amount of rainfall in mind.
※There are rivers for which the highest amount of rainfall has not been calculated. (These rivers are indicated with Projected Scale on the map.)

2 Nagaoka-Style Evacuation Procedures ―To ensure that no one gets left behind―Three Procedures to Protect Your Life
If there is heavy ﬂooding, such as an overﬂow of the Shinano River, evacuation shelters set up by the city will not be able toaccommodate all of the citizens whose houses get ﬂooded. (There will not be enough space for an estimated 96,000 people.)
In order to ensure that No One Gets Left Behind, it is necessary to keep the number of people at the city s designated evacuation
shelters as low as possible. Thus, the city needs the cooperation of all of its citizens for the following evacuation procedures.

Basic Evacuation Procedures❶Evacuate by vehicle, etc. toareas that won t get ﬂooded.

❷Evacuate to the higher
ﬂoors of your house.

●Evacuating to a relative s or a trusted ●A large amount of stocked foodfriend s house will keep your stressand water are necessary.

●You might not be able to get into a facility due
to the number of evacuees.
●The space allotted for one person is very small.
●You will need to move your car to an area that
won t get ﬂooded.
●Evacuating to a facility with your own car is notallowed. This is to prevent traﬃc jams andobstacles to the passage of emergency
vehicles. (The general rule is evacuation on foot.)●The risk of contracting infectious diseases is high.

3 Information to Help You Determine What to Do
Keep the ideas of Each person should protect his own life by himself andWe should protect our own neighborhood by ourselves ﬁrmly in mind.
It is important to be conscious of protecting your own life by yourselves. Try to evacuate as quick as possible.
It is also important to say a few words to and help the elderly and any others who might have diﬃculties in evacuating on their own.

Information to Determine Whether to Evacuate and Actions You Should Take ―When Should I Evacuate?―

Conﬁrm what kind of dangers you might face and what evacuation procedures would be best for you fromyour house, oﬃce, school, and other places where you might be. ※Here, assuming that you are at home.

If there is a danger of a disaster occurring or if one has already occurred, it is important for you to gather information, determine your course of action, and start evacuation
procedures. Conﬁrm what kinds of information to gather, when to evacuate, and the actions you should take in case of a disaster, and ﬁll in these needed actions on the Check Sheet.

Step 1

Check the Danger to Your House on the Hazard Map

(Evacuating Your House)(Maintaining Your Safety Inside Your House)(Evacuating Your House)

You can maintain your safety by moving to higher ﬂoors inyour house. However, you might not be able to use electricity,gas, or water due to the ﬂood, and also there is a chance thatrainfall might exceed expectations and ﬂoodwaters mightreach the higher ﬂoors of your house. Therefore, it would be
best to evacuate to an area that won t get ﬂooded.

●Conﬁrm with your family and the community: a safe evacuation destination, yourevacuation route, and by what means you will evacuate. When deciding on an evacuationroute, it is extremely important that you avoid dangerous places such as subterraneantunnels, bridges, and landslide danger zones.
