Development Impact Assessment

Tree Dimensions provides reports at various stages of development to support the design process, accompany municipal planning applications and to guide tree protection during construction.

Tree reports for development sites comply with the guidelines of Australian Standard 4970–2009 Protection of trees on development sites.

What sort of report do I need for a proposed development?

Description of report types:

Preliminary Arboricultural Report (PAR):

For a PAR, Tree Dimensions identifies the trees present at a site; determines which trees are suitable for retention based on health, structural condition and other factors; and, explains what is required to viably retain suitable trees. A PAR is useful for guiding the site development design process.

Arboricultural Impact Assessment (AIA):

An AIA is required by planning departments of municipalities as a prerequisite of site development applications. As such, an AIA not only incorporates the content of a PAR, but also explains the impacts that a proposed development will have on trees, and stipulates the specific actions required to protect and viably maintain retained trees.

Tree Protection Specification and Plan (TPSP):

A TPSP sets out the information required to guide tree protection during all stages of development. The TPSP includes a Tree Protection Plan, showing trees to be removed, trees retained and their tree protection zones, and the location of fencing and other protection measures.

Trees that should be retained (green) or removed (red) can be identified prior to development design in a Preliminary Arboricultural Report (PAR).

Knowing the protection zones of retained trees prior to development design can save developers time and money.
