Council-Compliant Level 5 Tree Reports for DA and CDC Approvals
Our local Level 5 Arborists prepare DA and CDC tree reports for property owners across the Sutherland Shire Council area, supporting residential developments where trees may be retained, impacted or removed.
We assist property owners planning new dwellings, extensions, dual occupancies and alterations, providing clear, evidence-based arborist documentation used by Council when assessing Development Applications involving Tree Protection Zones (TPZs) and Structural Root Zones (SRZs).

What Is a DA Tree Report?
A DA Tree Report, also known as an Arboricultural Impact Assessment, is an independent professional assessment used by Council to determine whether trees can be retained, pruned or removed, how proposed development interacts with Tree Protection Zones (TPZs) and Structural Root Zones (SRZs), whether the works comply with AS 4970 - Protection of Trees on Development Sites, and what tree protection measures are required during construction.
If Trees Are Retained During Construction
Where trees are approved for retention, Sutherland Shire Council may require a Tree Protection Plan along with ongoing arborist involvement throughout construction.
In these cases, Level 5 Project Arborist services may be required to supervise works, monitor compliance within TPZs and SRZs, and provide certification during 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
- 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 construction.

Local Development Context – Sutherland Shire Property Owners
Caringbah, Miranda, Sylvania and Oyster Bay
In established residential suburbs, DA tree reports are commonly required for extensions and alterations where mature trees and limited setbacks result in TPZ or SRZ impacts.
Menai, Illawong, Bangor and Alfords Point
In bushland-edge residential areas, reports often address retained native trees, larger TPZ requirements and additional planning controls affecting low-density sites.
Cronulla, Woolooware, Greenhills Beach and Kurnell
In coastal suburbs, arborist reports frequently consider wind exposure, sandy soils and development impacts near long-established trees.
