What Is Clause 52.37 and How Does It Affect Development on the Mornington Peninsula?
Clause 52.37 is part of the Victorian Planning Scheme and applies where development affects canopy trees or requires canopy outcomes to be assessed as part of a Planning Permit application.
On the Mornington Peninsula, this clause plays an important role in how Council considers tree retention, tree removal, replacement canopy and long-term landscape outcomes. It is not just about whether a tree is present on site. It is about whether the proposed development can respond properly to canopy, soil conditions and planning controls.
In many cases, Clause 52.37 sits alongside other planning considerations such as overlays, site constraints, design layout and arboricultural reporting.
Our AQF Level 5 Arborists help property owners, builders, designers and developers understand how Clause 52.37 applies to their site, and what documentation is needed to support approval.
When Does Clause 52.37 Usually Apply?
Clause 52.37 commonly becomes relevant where:
- Development affects existing canopy trees
- Tree removal is proposed as part of a Planning Permit application
- New building works or subdivision impact tree retention
- Excavation approaches a Tree Protection Zone (TPZ)
- Trees must be assessed for long-term canopy performance
- Replacement canopy planting is required
- Site design must respond to deep soil and tree viability
- Other planning overlays apply to the land
Where these issues are triggered, Council will usually expect arboricultural assessment and clear supporting documentation.
What Is a Canopy Tree Under Clause 52.37?
A canopy tree is generally assessed by measurable physical thresholds and by its realistic long-term growth potential on the site.
This often includes consideration of:
- Tree height
- Trunk size
- Canopy spread
- Capacity to achieve a recognised canopy class
- Ability to perform under available soil and site conditions
On the Mornington Peninsula, canopy assessment is not based on how the tree looks at planting. It is based on whether the species and site conditions can support a realistic mature canopy outcome over time.
Canopy Classes and Long-Term Tree Performance
Clause 52.37 commonly works around canopy class expectations such as:
- 6 metre canopy
- 8 metre canopy
- 12 metre canopy
These categories help Council assess whether tree planting or retention will contribute meaningfully to canopy cover.
Smaller sites may only support modest canopy outcomes, while larger or better-designed sites may be expected to support larger trees. The important point is that canopy size must match available soil, site conditions, setbacks and overall viability.
Council is not simply looking for a tree on paper. It is assessing whether the proposed canopy outcome is realistic and sustainable.
Why Deep Soil Matters Under Clause 52.37
Deep soil is one of the main factors in whether canopy outcomes can actually be achieved.
For a tree to perform properly over time, soil conditions must allow for:
- Root plate development
- Structural stability
- Water infiltration and drainage
- Adequate soil volume
- Long-term canopy growth
Where deep soil is fragmented, too shallow, located above structures, or interrupted by services and foundations, canopy outcomes are often unrealistic.
This is why deep soil is often a key reason for Requests for Further Information, redesign, or refusal during Planning Permit assessment.
Tree Retention and Tree Removal Under Clause 52.37
Clause 52.37 generally supports a retention-first approach.
This means Council will usually consider:
- Whether the tree can be retained through better design
- Whether the layout can be adjusted to reduce impacts
- Whether driveways, services or excavation can be repositioned
- Whether the tree is healthy, structurally sound and worth retaining
- Whether removal has been clearly justified by arboricultural evidence
Tree removal is not assessed in isolation. It is assessed as part of the overall development response, including site layout, canopy impact and long-term landscape outcomes.
Where removal is supported, Council may still require replacement planting and functional soil conditions to maintain canopy performance over time.
What Supporting Documentation Is Usually Required?
The required documentation will vary from site to site, but all of it must show that the development has properly addressed canopy retention, tree protection and planning compliance.
Why Clause 52.37 Matters
Clause 52.37 is intended to improve long-term canopy outcomes across developed areas. On the Mornington Peninsula, this also connects with broader planning concerns such as coastal character, vegetation protection and neighbourhood landscape identity.
It matters because it influences:
- Whether trees can be removed
- Whether replacement planting is acceptable
- Whether retained trees can survive construction
- Whether deep soil is functional
- Whether the development is likely to gain approval without delays
If Clause 52.37 is not addressed properly, projects commonly face Requests for Further Information, redesign, delayed decisions or refusal.
Local Planning Context – Mornington Peninsula
Across Mornington, Mount Eliza, Mount Martha, Dromana and Somerville, redevelopment often occurs on sites with retained trees, constrained access and existing vegetation that must be considered early in design.
In coastal areas such as Rosebud, Rye, Blairgowrie and Sorrento, canopy performance is also influenced by sandy soils, wind exposure and coastal conditions, making realistic tree selection and deep soil planning even more important.
Understanding Clause 52.37 early helps avoid unnecessary redesign and strengthens Planning Permit outcomes across the Mornington Peninsula.
Frequently Asked Questions
No. It generally applies where canopy trees are affected, tree removal is proposed, or canopy outcomes must be addressed as part of a Planning Permit application.
In many cases, yes. A Level 5 arborist report is often required where development affects trees, root zones, canopy retention or removal justification.
Not necessarily. Council assesses more than appearance. It considers canopy contribution, tree condition, planning controls, site context and whether removal has been properly justified.
Deep soil is critical. Without adequate soil conditions, retained or replacement trees are unlikely to achieve realistic mature canopy outcomes, which can affect approval.
