Trees on Residential Verges

Benefits of trees

Trees are an important part of any City and provide various benefits. Trees may increase property values, reduce heat in our suburbs and promote well-being. Trees clean the air, create natural screens and provide habitat. They act as wind and noise buffers and reduce the need for artificial cooling in adjacent buildings.

Verge trees for residents

The City offers trees for resident's verges, covering the cost of purchasing, planting and future pruning. While the City will water the tree for the first three years, residents are encouraged to supplement these waterings. If residents have irrigation, we ask that they let the City know. It costs the City approximately $992 per residential tree to purchase and maintain for three years.

If you would like a tree planted on your verge, please contact us. A City officer will aim to contact you within 30 business days of your request to discuss the type of tree(s) and its location.

What tree species can I choose?

The type of tree species received depends on"
  • Where the resident lives (zone), as different species are suited to different environments
  • Width of the verge
  • Overhead power lines 
  • Context of where the tree is most likely to be planted.
The City typically plants small to medium-sized tree stock, as they are easier to establish and consistently outgrow larger trees. Once mature, the trees grow approximately 4-15 metres tall.

When will my verge tree be planted?

Once the tree species has been decided, the City adds it to its seasonal tree order, which is submitted to the nursery to grow, generally 12 months before the planting season. The majority of residential trees are planted from May to October each year. Depending on when you request a tree, it can take between one to 12 months for it to be planted on your verge.

Residential verge tree pruning
The City is responsible for pruning all trees on residential verges in Cockburn. The City follows the Australian Pruning Standards, which determine whether a tree should be pruned and the type of pruning done. The Australian standard does not cover powerline clearance pruning as this is done to industry best practice as per Western Power line clearance requirements. 
 
Following Australian Standards, the City will consider pruning a tree if it:
  • Improves the safety, structure and health of the tree 
  • Provides clearance for people and vehicles moving below the tree. Generally, this is a minimum of 2m over the footpath and 3.5-4.5m over a carriageway or road 
  • Prevents branches from overhanging a property boundary
  • Maintains safe clearance zones from powerlines as per Western Power requirements
  • Maintains a clear line of sight for vehicles and cyclists.
The City will generally not prune a tree if:
  • Allergies are experienced by a resident/s
  • The tree is dropping leaves (the City undertakes scheduled and additional road sweeping in areas with heavy leaf litter)
  • The tree is shading solar panels
  • The tree is blocking views. 

How to get your verge tree pruned
