Arborist Reports for Builders and Architects
Our local AQF Level 5 Arborists prepare DA and CDC arborist reports for builders and architects across the Sutherland Shire Council area, supporting residential, mixed-use and infill developments where trees may be retained, impacted or removed.
We collaborate with builders, architects and designers to identify and resolve tree-related constraints early in the process, providing clear and defensible documentation aligned with Council expectations when assessing proposals involving Tree Protection Zones (TPZs) and Structural Root Zones (SRZs).
Engaging an arborist early in the design phase helps reduce the need for redesign, limits approval delays, and supports a smoother transition from planning through to construction.

If Trees Are Retained During Construction
Where trees are approved for retention, Sutherland Shire Council may require a Tree Protection Plan and ongoing Project Arborist involvement during construction.
In these cases, Level 5 Project Arborist services may be required to supervise works, monitor compliance within TPZs and SRZs, and provide during the construction phase.
This typically applies where building works occur near retained trees, services pass through root zones, or arborist supervision is included as a condition of consent.
How Tree Protection and Project Arborist Services Work Together
- TPZ and SRZ controls
- Tree protection fencing
- No-go zones and site restrictions
Project Arborist services ensure these controls are properly implemented, monitored and certified throughout the construction process.
Frequently Asked Questions
At what design stage do TPZ and SRZ constraints need to be resolved?
Before plans are finalised to avoid redesign and DA approval delays.
TPZ and SRZ constraints should be addressed during concept and schematic design to minimise redesign costs and reduce Council RFIs.
What tree documentation do Councils expect for a DA or CDC?
A Level 5 Arborist Report with TPZ and SRZ mapping and impact assessment.
Councils expect reports prepared in accordance with AS 4970, including tree condition, impact assessment and clear recommendations.
When is a Project Arborist required?
When trees are retained near construction or supervision is a condition of consent.
Project Arborists are typically required where works occur within TPZs or SRZs or where supervision is mandated by Council.
What happens if TPZ rules are not followed on site?
Non-compliance can lead to stop-work orders, fines or approval delays.
Failure to comply may result in enforcement action, required redesign or delays at the occupation certificate stage.
Local Development Context – Sutherland Shire
Infill and redevelopment areas such as Caringbah, Miranda, Kirrawee and Sutherland commonly involve constrained sites and retained trees requiring detailed arborist input.
Bushland-interface and constrained locations including Engadine, Heathcote, Menai and Illawong often involve retained native vegetation, slope conditions and environmental constraints that require careful TPZ and SRZ management.
Foreshore and coastal suburbs such as Cronulla, Burraneer, Dolans Bay and Port Hacking frequently require additional arborist coordination due to wind exposure, salt influence and strict vegetation controls.
