About development impact reports
A development impact report, also called an arboricultural impact assessment, identifies the protected trees on a development site and assesses how the proposed works will affect them. It follows Australian Standard AS 4970-2009, Protection of Trees on Development Sites.
Our qualified consulting arborist reports on the trees identified in the preliminary tree assessment and assesses the impact of the design, in line with council regulations and AS 4970-2009. This level of reporting needs a good understanding of both construction techniques and tree biology.
It also needs good communication between the consulting arborist, designers and builders, which is where our experience on working sites helps.
What the report includes
Tree protection zones
TPZ and structural root zone calculated for each retained tree.
Impact assessment
How excavation, services and structures will affect each tree.
Remove, retain, transplant
Clear recommendations for every affected tree.
Design advice
Changes that could reduce the impact, such as alternative footings.
Protection measures
Feeding into the tree protection plan.
Council-ready format
Written to support your development application.
Guiding sustainable development
Development impact reports show how construction will affect existing trees and the wider landscape. We help developers put strategies in place that protect trees and keep the project compliant.
By setting out tree health and risk clearly, our reports guide sustainable development, reduce environmental impact and support long-term landscape stability.
- Compliant with AS 4970-2009
- Fewer delays at assessment
- Lower environmental impact
Simple, start to finish
One team handles the quote, the paperwork and the work itself, so nothing falls between the gaps.

Development Impact Reports questions
What is AS 4970-2009?
It’s the Australian Standard for protecting trees on development sites. It sets out how to calculate tree protection zones and what measures are needed during construction.
Is a development impact report the same as an arboricultural impact assessment?
Yes. The two names are used for the same type of report.
Do I need a preliminary tree assessment first?
Usually, yes. The preliminary assessment records the trees; the impact report assesses how your design affects them.
Can you work with my architect or engineer?
Yes. We liaise with designers and builders to find solutions that protect trees without derailing the project.
