I want to know the boundary between Public Works Office roads and waterways (boundary survey)

Public Works Office conducts boundary surveys to clarify the boundaries between roads and waterways. Boundary survey is to clarify the boundaries between roads, rivers, waterways, etc. managed by Yokohama City and the land in contact with them.
When person who owns land in contact with road and waterway needs boundary investigation, by application from the person concerned, related landowner and Yokohama-shi will discuss witness by application from that person.
When this witness consultation is established, the boundary is determined, and a boundary mark is set up and a boundary survey map is created. Boundary survey maps can be used for buying and selling land, land area correction, writing brushes, etc.
There are two types of boundary surveys: boundary identification that determines the boundary with the roadway and waterway, and boundary restoration that restores when the boundary of the point where the survey was conducted is lost and unknown.
＊Before applying, please check in Public Works Office for documents related to boundaries, such as boundary survey maps and road ledgers.
＊We do not conduct boundary surveys between private land and private land.

When boundary investigation is necessary, please submit the following documents to city (Public Works Office).
