Full Development Lifecycle Tree Compliance – Concept to Occupation Certificate, Newcastle
One arborist. Consistent advice from site acquisition to occupation certificate.
We manage tree compliance for development projects across Newcastle City Council, from pre-design tree surveys and Arboricultural Impact Assessment (AIA) preparation through construction supervision and final Council certification.
Because our Project Arborist is an AQF Level 5 consulting arborist, they write the AIA and supervise the construction. The same person. No handoff. No knowledge gap between the report and the site.

What Is a Project Arborist and What Do They Do?
A Project Arborist is a consulting arborist responsible for tree compliance across the full development lifecycle, from the first site survey through to the occupation certificate. The role is distinct from a one-off AIA report. The Project Arborist stays with the project.
At Planning Stage
- Pre-design tree survey and TPZ constraint mapping, before plans are finalised
- Arboricultural Impact Assessment (AIA) for DA and CDC applications, written by the same arborist who will supervise construction
- TPZ and SRZ calculations mapped directly against architectural drawings, AS4970-2009 compliant
- DCP 2023 and Urban Forest Technical Manual Part A compliance, all removal tests documented
- Heritage Conservation Area flags, Heritage Minor Works requirements identified early
- Biodiversity Conservation SEPP 2021 wetland triggers, Native Vegetation Removal Permit requirements identified
- Council RFI responses, arboricultural sections handled directly
- Tree retention and removal justification
At Construction Stage
- Tree Protection Plan (TPP), AS4970-2009 compliant
- TPZ fencing, ground protection and exclusion zone specification
- Pre-construction site establishment, protection measures installed and verified
- On-site supervision at key construction stages including footing excavation, services and concrete pours
- Encroachment management, minor, moderate and major classifications under AS4970-2009
- Root investigation, AirSpade excavation to expose and map roots within TPZ and SRZ
- Structural condition assessment where required
- Final arborist certification, written sign-off for Council occupation certificate conditions
One arborist. Consistent professional judgement from first site visit to OC sign-off.
The Arboricultural Impact Assessment – Written by Your Project Arborist, Not Handed Off
On most development projects the AIA and the Project Arborist role are inseparable. The arborist who assessed the trees and wrote the report is the same person on site during construction, so the TPZ constraints, retention decisions and removal justifications in the AIA are understood and applied correctly throughout the build.
This matters because:
- No knowledge gap – the arborist who mapped the TPZs is the person verifying they are respected on site
- Consistent Council documentation – the AIA, TPP and final certification all carry the same arborist's name and professional judgement
- RFI response – if Council queries the AIA, the author responds directly, not a colleague reading someone else's report
- One point of contact, from pre-design survey through to occupation certificate
AIA reports not aligned to plans or missing DCP 2023 requirements are a common cause of RFIs from Newcastle City Council. Because our Project Arborist writes the AIA against your architectural drawings from the start, this risk is managed before lodgement, not after.

When Should a Project Arborist Be Engaged?
At concept stage, before plans are finalised.
Early engagement is the single most effective way to reduce RFIs, prevent redesign and avoid programme delays. In Newcastle, where DCP 2023, Heritage Conservation Areas and Biodiversity Conservation SEPP 2021 wetland buffers apply across a wide range of development sites, tree constraints identified late in the design process are expensive to resolve.
Engage a Project Arborist:
- Before finalising the building footprint, driveway layout or service runs
- During DA preparation, prior to AIA lodgement
- When Council requires supervision as a condition of DA approval
- Where trees are retained within or near proposed works
- On sites with TPZ or SRZ encroachment
- For multi-dwelling, dual occupancy or subdivision projects
- On sites near Heritage Conservation Areas or Biodiversity Conservation SEPP 2021 wetland buffers
- Where the previous arborist's report drew an RFI - we review and respond
Adjusting at concept costs nothing. Redesigning after DA lodgement costs time and money, and in Newcastle's active development market, programme delays are expensive.
Construction-Stage Arborist Services – AS4970-2009 Supervision and Certification
Once DA approval is issued, the Project Arborist oversees tree protection throughout construction, verifying compliance at each stage and certifying completion for Council conditions.
Our construction-stage arborist services cover all AS4970-2009 required stages:
- Tree Protection Plan (TPP), protection zones, fencing specification and ground protection
- Pre-construction site establishment, TPZ fencing and protection measures installed and verified
- Encroachment management, minor, moderate and major under AS4970-2009
- Root investigation, AirSpade excavation within TPZ and SRZ
- Construction supervision at key stages including footing excavation, services installation and concrete pours
- Structural assessment where required
- Final arborist certification, written sign-off for Council occupation certificate conditions
Missing a required supervision inspection or failing to certify compliance can delay your occupation certificate. We programme site visits around your construction schedule to prevent this.
Newcastle Development Context – What to Expect by Area
Inner City – Cooks Hill, The Hill, Newcastle East, Bar Beach, Merewether, The Junction
Heritage Conservation Areas apply across much of inner Newcastle. Heritage Minor Works Permit required alongside DCP 2023 compliance. Large garden specimens with significant TPZ extents. High Council scrutiny on removal justification. Build heritage assessment lead time into your programme from the start. Late identification causes the most expensive delays on inner city projects.
Inner West – Hamilton, Mayfield, Islington, Wickham, Broadmeadow, Carrington
Highest DA volume in the LGA. Mature street trees frequently sit within the TPZ of proposed footprints, driveways and setbacks, constraints invisible until concept-stage mapping is done. Hamilton and Mayfield are the two suburbs where late Project Arborist engagement most consistently causes redesign delays and RFIs.
Western Suburbs – Adamstown, New Lambton, Kotara, Lambton, Waratah, Georgetown, Elermore Vale
Established family blocks with large Brushbox and eucalypts. Many trees have not been correctly maintained and show the effects of historical topping, a common trigger for a full structural assessment before further pruning proceeds. The 10% live canopy rule catches many owners by surprise in this belt.
Northern Growth Corridor – Fletcher, Maryland, Minmi, Wallsend, Beresfield, Tarro, Hexham
Active DA pipeline, subdivision, multi-dwelling housing and new estate development across the LGA's fastest-growing corridor. Project Arborist services may be required from concept through to occupation certificate, depending on DA conditions and retained trees. Shortland Wetlands proximity triggers Biodiversity Conservation SEPP 2021 assessment on some sites. Identify early in your programme.
Coastal and Wetland Sites – Stockton, Hexham, Warabrook, Tarro
Biodiversity Conservation SEPP 2021 wetland buffers apply across parts of these suburbs. Trees within 100m of a Biodiversity Conservation SEPP 2021 wetland require a Native Vegetation Removal Permit, a separate process from the standard DCP 2023 path. Miss this trigger at DA lodgement and you are looking at a resubmission. We identify it at concept stage.
