Sydney’s Tree Clearance Laws: What Are the Legal Requirements?

Navigating tree clearance laws in Sydney can be complex for property owners. From pruning to removal, ensuring compliance with local regulations is vital for the safety of your property and the surrounding community. Here’s a simplified guide to what’s required when clearing trees on your property.

Understanding Local Council Regulations

Each local government area (LGA) in Sydney has its own regulations regarding tree clearance. These regulations can differ depending on your location, so it’s important to check the specific guidelines for your area.

  • Local Regulations: Councils set rules about how, when, and if trees can be pruned or removed.
  • Council-Specific Guidelines: Always consult your local council's website or office for the most up-to-date information.
  • Potential Fines: Non-compliance can result in substantial fines, making it essential to understand and follow these rules.

Tree Preservation Orders (TPO)

In Sydney, many councils enforce Tree Preservation Orders (TPOs) to protect significant trees. TPOs prevent the removal or pruning of certain trees without council approval.

TPO Criteria: TPOs apply to trees that meet certain criteria:

  • Size: Trees with a certain height or trunk circumference.
  • Species: Indigenous species or those with cultural, historical, or ecological significance.
  • Location: Trees in conservation areas or on heritage-listed properties.

How to Check if Your Tree is Protected

  • Contact Your Council: Verify if your tree falls under a TPO and needs a permit for pruning or removal.
  • Arborist Assessment: An arborist can assess whether your tree qualifies for protection under a TPO.

Development Control Plans (DCP)

Development Control Plans (DCPs) outline the guidelines for managing trees during property development projects.

  • Tree Retention: DCPs may require trees to be retained during development.
  • Replacement Trees: You may need to plant new trees if any are removed as part of a development.
  • Impact Assessments: DCPs may require an assessment of how tree removal affects the local environment.

Obtaining the Necessary Permits

If your tree is protected under a TPO or other local regulations, you will likely need a permit for removal or substantial pruning. Here’s how the permit application process works:

  1. Assessment of the Tree: Have an arborist evaluate the tree’s health and structure. Their professional assessment can help support your application.
  2. Submit the Application: Submit the application to your local council with details of the tree, its location, and reasons for pruning or removal.
  3. Council Review: The council will review your application and may request a site inspection to evaluate the tree’s health and potential environmental impact.
  4. Approval and Conditions: If approved, the permit may include conditions such as replanting requirements or specific methods for removal to minimise environmental impact.

Exemptions and Emergency Situations

Some situations may allow tree removal without a permit, especially if there are safety concerns.

  • Dangerous Trees: If a tree poses an immediate risk, it can often be removed without a permit. Photographic evidence or an arborist's report may be required to justify emergency action.
  • Minor Pruning: Some councils may not require a permit for minor pruning if it doesn’t significantly affect the tree’s health.

Who Is Responsible for Tree Trimming Near Powerlines?

Maintaining safe distances between trees and powerlines is critical for preventing hazards. Responsibility for tree trimming is shared between utility companies, local councils, and private property owners. Here's a breakdown of each party's role:

Utility Companies (Ausgrid and Endeavour Energy)

Utility companies like Ausgrid and Endeavour Energy are responsible for vegetation management near high-voltage powerlines.

  • Vegetation Management: These companies oversee the clearance of trees near powerlines to avoid power outages, fires, and safety hazards.
  • Scheduled Inspections: Regular inspections help identify any vegetation that may interfere with powerlines.
  • Trained Arborists: Qualified arborists carry out maintenance around live electrical infrastructure.

Local Councils

Local councils play a key role in managing trees in public spaces and coordinating with utility companies to ensure powerlines remain clear.

  • Public Land Maintenance: Councils manage trees in public spaces such as parks, roadsides, and reserves.
  • Resident Reporting: If you notice a tree on public land posing a risk to powerlines, you can report it to your local council.

Private Property Owners

Private property owners are primarily responsible for ensuring their trees don’t encroach on safety clearance zones for powerlines.

  • Clearance Zones: Property owners must ensure their trees maintain the required distance from powerlines.
  • Engaging Professionals: Property owners should hire certified arborists for safe trimming or removal of trees near powerlines.

What Happens If You Trim Trees Too Close to Powerlines?

Trimming trees near powerlines without proper care can lead to serious consequences, including safety hazards, legal issues, and power supply interruptions.

Safety Hazards

  • Electrocution Risk: Even indirect contact with live powerlines can cause electrocution.
  • Electrical Arcing: Electricity can jump from powerlines to nearby objects, such as trees or tools.

Fire Hazards

  • Bushfire Risk: Trees too close to powerlines can ignite, especially in dry weather, leading to bushfires.

Legal Consequences

  • Fines and Liabilities: Failing to follow regulations can result in fines, legal action, and costly repairs.
  • Property Owner Responsibility: Property owners may be held liable for damage caused by improper trimming.

Signs a Tree Is Too Close to Powerlines (And What to Do Next)

To maintain safety and prevent damage, it's crucial to monitor trees near powerlines for potential risks.

Recognising the Warning Signs

  • Physical Proximity: If branches are touching or too close to powerlines, it’s time to take action.
  • Damage: Broken branches, scorched leaves, or unnatural leaning can indicate a risk.
  • Swaying: If branches move dangerously close to powerlines, they may need trimming.

What to Do Next

  • Contact a Certified Arborist: For professional advice and tree assessment.
  • Regular Maintenance: Regularly prune trees to prevent interference with powerlines.
  • Engage Local Authorities: Report any immediate safety risks to the appropriate authorities.

Safe Species to Plant Near Powerlines in Sydney

Choosing the right tree species near powerlines is crucial to prevent safety hazards.

Criteria for Safe Tree Selection

  • Mature Height: Choose trees that won’t exceed 3-4 metres at maturity.
  • Slow Growing: Opt for slow-growing trees that require less maintenance.
  • Non-Invasive Roots: Ensure the tree’s roots won’t damage underground utilities.

What to Do After Storm Damage Involving Powerlines

Storms can cause significant damage, and when trees or branches fall onto powerlines, the risk becomes a serious safety concern. In Sydney's North Shore, it’s essential to know the right steps to take to avoid danger and ensure quick, effective resolution. Here’s a guide to what you should do when faced with storm damage involving powerlines.

Assess the Situation Safely

The first thing you should do after a storm is assess the damage — but always from a safe distance.

  • Stay at least 8 metres away from fallen powerlines. Even if the powerlines appear to be down, they could still be live, posing an immediate risk of electric shock.
  • Avoid touching debris or branches that are near powerlines, as they may still be conducting electricity.
  • Look for hazards such as fallen trees, branches, or poles in contact with powerlines, and be mindful of debris on the ground that could pose tripping or electrical risks.

Report the Damage

Once you’ve safely assessed the situation, it’s crucial to report the damage to the appropriate authorities.

  • Contact Ausgrid: As Sydney’s primary electricity provider, they need to know about any fallen powerlines or other risks to the power grid. You can report damage directly through their emergency hotline or website.
  • Call Emergency Services (000): If the situation involves immediate risk to public safety, such as powerlines hanging low or a fire hazard, do not hesitate to contact 000 for urgent assistance.

Wait for Professional Assistance

  • Do not attempt to intervene: Only qualified technicians, such as Ausgrid emergency services or certified arborists, should handle powerline-related issues.
  • Allow time for professional assessment: Electrical technicians will inspect and clear the area safely, while arborists will address any tree damage after the powerlines are declared safe.

Engaging Professional Tree Services

  • Once the area is deemed safe, call North Shore Tree Services or another professional tree care service to assess and address any tree damage.
  • Safety and efficiency: Our arborists are fully equipped to handle the post-storm cleanup, including any tree removals or trimming necessary to restore your property while ensuring safety around powerlines.

How Often Should Trees Near Powerlines Be Inspected or Trimmed?

Proper maintenance of trees near powerlines is essential for preventing hazardous situations. Regular inspections and trimming are necessary to keep both trees and powerlines safe, particularly in a storm-prone area like Sydney.

Regular Inspections

  • Annual Arborist Inspections: Trees near powerlines should be inspected by a certified arborist at least once a year.
  • Growth assessments: The arborist will evaluate the tree’s growth and its distance from powerlines.
  • Risk identification: Inspections help detect potential hazards, such as branches growing too close to wires or structural weaknesses in trees that could lead to future issues.

Scheduled Trimming

Trimming Frequency: Generally, trees near powerlines need trimming every 1-3 years depending on:

  • Growth rate: Fast-growing species require more frequent trimming.
  • Species type: Some species may have more aggressive growth, necessitating more regular maintenance.
  • Proximity to powerlines: Trees that are closer to powerlines will need more frequent attention to maintain safe clearance.

Compliance with Regulations

  • NSW Clearance Laws: In New South Wales, strict clearance laws dictate how much space must exist between trees and powerlines.
  • Residential responsibility: Property owners are responsible for maintaining proper clearance on their land.
  • Avoid power outages: Proper clearance helps prevent outages caused by fallen branches during storms.
  • Safety regulations: Compliance with these laws ensures the safety of residents, the public, and utility workers.
