Tree Maintenance
Proper care and maintenance is essential for trees in urban areas. Well maintained
trees become established more quickly after planting; are less likely to
conflict with buildings, infrastructure, and visual clearance; are healthier
and more aesthetically pleasing; and will be less hazardous as they age.
The Tigard Municipal Code addresses proper care and maintenance of trees
in a variety of sections that are described in more detail below. In
addition, there are many educational and professional resources
available to assist people in the proper care and maintenance of trees.
View the tree maintenance resources below for more information on topics such as how to
properly care for trees and how to hire certified arborists.

Tigard's Tree Maintenance Regulations:
The Tigard Municipal Code contains a variety of sections that address tree maintenance.
Section 7.40.060 requires property
owners to maintain tree branches at a height of no less than 8' over sidewalks
and no less than 10' over streets. It also requires property owners to
maintain their trees so that they do not pose safety hazards to the public.
These requirements apply to both street trees (in the public right of way)
and landscape trees on private property. Section 060.2.d of the
Tigard Tree Manual has further branch clearance requirements based on street type.
Sections 9.06.030 and 9.06.040 require
newly planted and established trees on City property to be maintained per the requirements
of Sections 030 and 060
respectively of the Tigard Tree Manual. These requirements apply to the maintenance
of street trees by private property owners as well.
Section 18.745.030 requires
that trees planted per a development code requirement be properly maintained. This
requirement applies to street trees, parking lot trees, buffer trees and any other
tree required as part of development approval. Section 18.745.030.F and 18.745.040.D
have further specifications regarding property owners' maintenance responsibilities
for street trees.
