Frequently Asked Questions
When do I need a permit to remove a tree in Ku-ring-gai?
Most trees over 5 metres in height or 150 mm trunk diameter require Council approval. We assess the tree and prepare the Level 5 arborist report required for approval.
Can I prune my tree without approval?
Minor pruning may be permitted; however, structural pruning generally requires approval. Deadwood removal, small branches or exempt species may be pruned without a permit. We confirm what is allowed.
What standard governs tree pruning?
All pruning must comply with AS 4373 – Pruning of Amenity Trees. This standard ensures correct pruning techniques that protect tree health and safety. Our reports specify compliant methods.
Does Council require an arborist report for construction?
Yes. DA and CDC developments must comply with AS 4970. We prepare full AS 4970 documentation including TPZ/SRZ mapping, impact assessments and tree protection plans.
What if a tree is dangerous or dying?
Dangerous or dead trees may be eligible for removal but still require Level 5 arborist confirmation. We inspect, document risk and provide reports accepted by Council and insurers.
