Overview of Boundary Survey

Boundary survey is to clarify the boundary between roads, rivers, waterways, etc. managed by Yokohama City and the land in contact with them.
When the person who owns the land in contact with the road or waterway needs a boundary survey, the relevant landowner and Yokohama City will have a witness consultation by application from that person.
When this witness consultation is established, the boundary is determined, and a boundary mark is set up to create a boundary survey map. The boundary survey map can be used for buying and selling land, land area correction, writing brushes, etc.
(In the boundary survey, when the boundary is undetermined, the relevant landowner and the city will be present to determine the boundary, and when the boundary has already been determined but becomes unclear, There is a "boundary restoration" to check again. Before applying, please check if there are any documents related to the boundary, such as the boundary survey map of the Public Works Office Roadway and the road ledger of the Road Investigation Division. )
