About maintenance of street trees and self-financing construction

Regarding self-financing construction on existing street tree lines, we will continue to work on existing street tree lines.
Please refer to the guide for road self-financing construction application.

When maintaining street trees due to new construction of street trees or large-scale redevelopment, we have established general standards for street tree maintenance in order to secure a space where trees can grow healthy. For details on street tree installation standards such as the size of tree-planting basins, placement intervals of Takagi, tree species to be planted, and places that cannot be planted due to safety management, please contact the Public Works Office and Road and Highway Bureau Facility Division of each ward.

• Application for self-financing construction, etc.:Public Works Office, each district
• When constructing street trees for large-scale development of 1,000 m2 or more: Road and Highway Bureau Facility Division
