Expert Arborist Reports Across Hornsby, Waitara & Pennant Hills
Covering all suburbs across Hornsby Shire Council Ward B, including Hornsby, Waitara, Normanhurst, Pennant Hills, Thornleigh, Wahroonga and Westleigh. Wahroonga is shared with Ku-ring-gai Council, so check the correct council for your property.
This ward covers Hornsby Shire's town centre and established middle-ring suburbs, combining the ongoing redevelopment of the Hornsby CBD with leafy, established residential streets in Normanhurst, Thornleigh and Westleigh. Waitara sits close to the town centre and has seen its own share of redevelopment, while Wahroonga and Pennant Hills retain substantial mature canopy across larger residential blocks.
As a result, arborist reports here regularly need to address town centre and station-precinct redevelopment near retained street trees, alongside renovation and rebuild proposals on established residential blocks.
Which Arborist Report Do You Need?
Apartment and mixed-use Development Applications around the Hornsby and Waitara town centres, and renovations or rebuilds on established properties in Normanhurst, Thornleigh and Pennant Hills, are among the most common reasons property owners across this ward require an Arborist Report.
Town Centre Redevelopment & Established Streets
Hornsby and Waitara have seen significant apartment and mixed-use redevelopment around the town centre and station precinct, with projects regularly built around existing street trees and boundary vegetation shared between adjoining sites. This creates two planning challenges that arise less often in the Shire's lower-density suburbs:
Across Normanhurst, Thornleigh, Pennant Hills and Westleigh, established homes with mature gardens are regularly assessed for retention as part of renovation and second-storey addition proposals, where Council considers both the property's existing streetscape contribution and the tree's structural condition.
- staged construction sequencing around retained trees during longer construction programs typical of apartment developments; and
- Tree Protection Zone overlap where trees are located on or near shared boundaries between adjoining development sites.

Hornsby Shire Council Tree Guidelines in This Ward
The same Hornsby Shire Council tree and vegetation controls apply across the entire local government area under Council's Development Control Plan and, for native vegetation, the State Environmental Planning Policy (Biodiversity and Conservation) 2021. Within this ward, the most common planning trigger is town centre and station-precinct redevelopment. Apartment and mixed-use Development Applications around Hornsby and Waitara frequently require Arboricultural Impact Assessments addressing boundary trees and staged Tree Protection Plans due to the concentration of larger development projects in the ward. Check current thresholds and exemptions on the Hornsby Council tree requirements page.
Replacement planting: Hornsby Shire Council states that any tree approved for removal must be replaced with a tree of like habit that is indigenous to Hornsby Shire, planted as near as practicable to the removed tree. The replacement is to be grown to maturity and replaced if it fails to survive and thrive, in accordance with Council’s Green Offsets Code.
- Apartment and mixed-use developments commonly require Arboricultural Impact Assessments at Development Application stage.
- Boundary trees often require careful assessment where Tree Protection Zones extend onto neighbouring properties.
- Renovation and rebuild proposals in Normanhurst, Thornleigh and Pennant Hills commonly require Tree Protection Zone assessment alongside standard reports.
- All trees are protected unless an exemption applies: a tree is a long-lived woody perennial with the potential to grow taller than 3 metres. Trees under 3 metres outside native vegetation, exempt species, and trees within 3 metres of an approved building's foundation (excluding garages, carports and ancillary buildings) are among the exemptions, which do not apply on Biodiversity-mapped land, in Heritage Conservation Areas or on heritage items.
- We assess your site, explain the relevant approval pathway and prepare the appropriate Arborist Report before work begins.

Frequently Asked Questions
Boundary trees on town centre sites often require assessment as part of your own Development Application, particularly where your Tree Protection Zone extends onto or from a neighbouring lot. We assess the tree and your proposed works together and advise on the appropriate approach.
Larger apartment developments commonly require a staged Tree Protection Plan rather than a single set of measures for the whole project, with Project Arborist inspections at each construction phase to confirm retained trees remain protected.
An Arborist Report typically assesses tree health, structural condition, retention value and, where relevant to a Development Application, Tree Protection Zones (TPZs) and Structural Root Zones (SRZs), along with recommendations for protecting retained trees during construction.
In most cases, yes. Under Hornsby Development Control Plan 2024 (section 1.2.6), a tree is a long-lived woody perennial plant with the potential to grow taller than 3 metres, and all trees are protected unless an exemption applies. Exemptions include trees under 3 metres in height that are not in native vegetation, trees on Council's exempt species list, trees whose trunk base is within 3 metres of the foundation of an approved building (excluding detached garages, carports and ancillary buildings), and dead or imminent-risk trees where Council or an AQF Level 5 arborist has confirmed the evidence. The exemptions do not apply on land mapped as Biodiversity, in Heritage Conservation Areas or on heritage items. For standalone private-tree removal, pruning or Tree Permit questions unrelated to development, Hornsby Tree Permit Services can check the Council pathway first.
