Immediately upon the announcement of sediment-related disaster warning information in Midori Ward, evacuation warning Target Area, Flood, Inland Water and Sediment Hazard Map

Based on the lessons learned from Typhoon No. 18 in October 2014, Yokohama City decided to extract cliffs that could cause significant damage to houses in the event of a landslide, and to issue a "evacuation warning" with the announcement of "Earthquake Disaster Warning Information" to the surrounding area.
There are two target areas in Midori Ward.
It does not mean that the area where evacuation warning has not been issued is safe. In the event of a heavy rain or typhoon, pay attention to disaster prevention information and take evacuation actions as soon as possible at your own discretion.

　In order to ensure smooth and prompt evacuation during floods, information on evacuation sites and other areas is displayed in the flood inundation area map, which shows the estimated flood inundation area and assumed water depth, which is expected to be flooded when rivers are flooded due to the largest possible rainfall.
If you are difficult to see at the scale of the hazard map, please also use the "Wai Wai Disaster Prevention Map" (outside site) (outside site).

If Kanagawa Prefecture designates sediment-related disaster warning areas based on the "Law Concerning the Promotion of Sediment-related Disaster Prevention Measures in Sediment-related Disaster Warning Areas (commonly known as the Sediment-related Disaster Prevention Law), Yokohama City will create and publish hazard maps. going.
This hazard map shows areas where landslides may occur due to heavy rains associated with torrential rainfalls during the rainy season or typhoons, etc. It was created so that citizens can take appropriate actions such as evacuation.
※As we can confirm about earth and sand disaster caution area from Yokohama citizen disaster prevention information "wei Wai disaster prevention map (earth and sand disaster)" (outside site),
If you are difficult to see at the scale of the hazard map, please also use the "Wai Wai Disaster Prevention Map" (outside site).
In addition, we distribute earth and sand disaster hazard map in each ward ward office.

※About confirmation of detailed position such as earth and sand disaster caution areas
Earth and sand disaster hazard map shows general positions such as earth and sand disaster caution areas. The sediment-related disaster warning areas on the map are those at the time of creating the sediment-related disaster hazard map and may differ from the current designated situation. For legal drawings on sediment-related disaster warning areas, etc., please refer to the notification book of "areas where there is a risk of sediment-related disasters" on the Kanagawa Prefectural Sediment-related Disaster Information Portal (outside site) or contact the Yokohama Kawasaki Flood Control Office in Kanagawa Prefecture. Please contact us.

　It is a map that summarizes various information such as areas where flooding is expected during heavy rain and depth of flooding.
This map is used to facilitate smooth evacuation actions against inundation and to raise awareness of disaster prevention during normal times.
When searching from Address, etc., and detailed drawings are available.
Please utilize "Yokohama-shi administration map reporting system (waiwai disaster prevention map) (outside site)" (outside site).

※Inland water: Heavy rain fills sewer pipes and waterways, and water overflows from manholes and rainwater masu.
※Flood: Heavy rain continues to rise, the water level of the river rises, exceeding the embankment or breaking the embankment, causing river water to overflow.
Request for Use
・Residential land lower than roads, such as basements and underground parking lots, may have a risk of rainwater entering regardless of the degree of flooding.
・Depending on the strength of the rain and how it falls, the flooded area and inundation depth may differ from the assumption.
・The inundation assumption of the inland water hazard map is made reflecting the maintenance situation such as rivers and sewers at the end of 2018.
・On the information side, how to use the inundation hazard map and how to prepare on a daily basis are described. Please take a look at it.
