Arborist Reports for Builders and Architects
Our local AQF Level 5 Arborists prepare DA and CDC Arborist Reports for builders and architects across the Lake Macquarie City Council area, supporting residential, mixed-use and infill developments where trees may be retained, impacted or removed.
We work closely with builders, architects and designers to resolve tree-related constraints early, providing clear, defensible documentation Council expects when assessing proposals involving Tree Protection Zones and Structural Root Zones.
Early arborist involvement helps design teams avoid redesign, minimise approval delays and move efficiently from planning to construction.

If Trees Are Retained During Construction
Where trees are approved for retention, Lake Macquarie City Council may require a Tree Protection Plan and ongoing 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 certification throughout the build phase.
This commonly applies where construction occurs close to retained trees, services pass through root zones, or arborist supervision is imposed as a condition of consent.
How Tree Protection and Project Arborist Services Fit Together
Tree Protection Plans define how retained trees must be protected during construction, including:
- TPZ and SRZ controls
- Tree protection fencing
- No-go zones and site restrictions
Project Arborist services ensure those controls are correctly implemented, monitored and certified during the build.
Together, these services help builders and architects avoid compliance breaches, prevent damage to retained trees and reduce delays at final approval or occupation certificate stages.
Frequently Asked Questions – Builders and Architects
At what design stage do TPZ and SRZ constraints need to be resolved?
TPZ and SRZ constraints should be resolved before plans are finalised to avoid redesign and DA approval delays.
These constraints should be addressed during concept and schematic design. Early arborist input allows layouts, footings and services to be adjusted before lodgement, reducing redesign costs and Council RFIs.
What tree documentation do Councils expect for a DA or CDC?
Councils expect a Level 5 Arborist Report with TPZ and SRZ mapping and impact assessment.
This report must be prepared in accordance with AS 4970 and include tree condition assessment, impact analysis, TPZ and SRZ calculations, and clear recommendations addressing development impacts.
When is a Project Arborist required?
A Project Arborist is typically required when trees are retained near construction or supervision is imposed as a DA condition.
This commonly occurs where works take place within TPZs or SRZs, or where Council conditions mandate inspections and certification during construction.
What happens if TPZ rules are not followed on site?
Failure to comply with TPZ or SRZ controls can trigger stop-work orders, fines or approval delays.
Non-compliance may result in enforcement action, damage to retained trees, redesign requirements or delays at occupation certificate stage.
