What Is Clause 52.37?
Clause 52.37 – Urban Tree Canopy is part of the Victorian Planning Scheme and applies to development within the Whitehorse City Council area.
It regulates how canopy trees are retained, removed and replaced as part of Planning Permit assessment, with the aim of increasing long-term urban tree canopy cover and maintaining neighbourhood landscape character.
When Does Clause 52.37 Apply?
Clause 52.37 is typically triggered where:
- Development impacts existing canopy trees
- Tree removal is proposed as part of a Planning Permit application
- Subdivision or multi-dwelling development occurs
- Excavation encroaches into a Tree Protection Zone (TPZ)
- Retained trees require assessment under AS 4970
- Overlay controls (SLO, VPO or Heritage) are also present
Where triggered, arboricultural documentation is generally required to support Planning Permit assessment.
What Is a Canopy Tree Under Clause 52.37?
A canopy tree is typically defined by measurable size thresholds, including:
- Minimum height (commonly 5 metres or greater)
- Trunk circumference exceeding specified limits
- Canopy spread capable of achieving defined canopy classes
Whitehorse assesses trees based on realistic mature canopy performance rather than planting size.
Canopy Class Framework
Clause 52.37 commonly applies canopy class categories:
Each canopy class must be supported by appropriate deep soil allocation and long-term viability.
Deep Soil & Canopy Performance
Canopy compliance is directly linked to soil performance.
- Adequate soil width, depth and volume
- Contiguous, unfragmented planting zones
- No basement interference within root zones
- Capacity to support mature canopy growth
Tree Retention & Removal Principles
Whitehorse applies a retention-first approach:
- Design modification should be considered before removal
- Removal must be supported by arboricultural justification
- Structural condition, risk and feasibility are assessed
- Replacement planting is typically required
Planning Permit & Arborist Documentation
Development proposals affected by Clause 52.37 typically require:
Documentation must address canopy impact, TPZ and SRZ compliance, and long-term tree viability.
Why Clause 52.37 Matters
Clause 52.37 is designed to:
- Increase urban tree canopy cover
- Protect neighbourhood landscape character
- Ensure development integrates with existing vegetation
- Promote sustainable long-term canopy outcomes
Failure to address these requirements can result in Planning Permit refusal, Requests for Further Information (RFIs) or redesign.
Local Context – Whitehorse VIC
Across Box Hill, Blackburn, Mitcham, Nunawading and Vermont South, development frequently interacts with established canopy trees, requiring careful coordination between design, arborist reporting and planning compliance.
Frequently Asked Questions – Clause 52.37
No. It applies where canopy trees are impacted or where Planning Permit triggers are met.
Smaller developments may still trigger assessment where trees are present or where excavation affects root zones.
In most cases, yes.
A Level 5 arborist report is typically required where development impacts trees or where canopy compliance must be demonstrated.
Only in limited circumstances.
Exemptions may apply depending on tree size, overlays and emergency conditions, but most development-related removal requires approval.
Deep soil is critical to canopy compliance.
Without adequate soil allocation, canopy trees are unlikely to be supported, which can lead to refusal or redesign.
