Why Do I Need an Arborist Report to accompany my Development Application?

It is often a requirement from local Councils to provide an Arborist Report as part of a Development Application to account for all tree impacts and tree removals as part of proposed works.

Arborist report requirements are outlined in the Australian Standard® Protection of Trees on Development Sites –AS 4970-2009.

Healthy trees will increase the property value and provide a more enjoyable living space. Tree care should be considered an investment as the benefits of trees are numerous.

At what stage should the Arborist become involved?

The Arborist should become involved at the beginning of the design process to provide a Preliminary Tree Assessment. The purpose of this is to allow the architectural and landscape design team to plan around the most valuable trees and to know which trees should not be a constraint to the design. This will prevent problems later on by overcoming tree issues before it is too late.

When the architectural and landscape design is complete, an Arboricultural Impact Assessment is required to identify trees required for removal, transplantation and retention. The report will explain what design and construction measures are required to minimize impacts on trees to be retained.


Tree Sensitive Design

Bluegum is able to conduct exploratory excavation around significant trees in order to map the location of tree roots. This allows exact specification of recommended construction offsets.
As part of the Development Application assessment, Bluegum will specify areas where tree sensitive construction methods are required. These may include:

  • Pier and beam footings
  • Suspended/canitlevered slabs
  • Raised landscape levels
  • Uncompacted subgrade materials
  • Permeable paving
  • Bridged wall sections (using lintels)
