Why You Might Need a Root Investigation
Our Northern Beaches tree root investigation service helps identify and prevent costly issues such as:

- Foundation Problems – Subsidence or shifting caused by root systems
- Developers and architects
- Homeowners with suspected root damage
- Engineers & certifiers needing compliance reports
What We Assess
Our root mapping process includes:
- Mapping root location and spread using non-invasive tools (e.g. AirSpade)
- Assessing root impact on driveways, slabs, retaining walls, and underground services
- Determining tree compatibility with proposed construction
- Providing clear recommendations: retain, prune, or remove
- Supplying council-ready documentation for development approvals
Council-Compliant Reports
Northern Beaches Council may require a Level 5 arborist report when:
- Trees are inside a Tree Protection Zone (TPZ) for a proposed development
- Roots are causing property or infrastructure damage
- Root intrusion justifies tree removal or pruning
- Reference AS4970:2009 Protection of Trees on Development Sites
- Include root mapping images and data
- Are formatted for quick council acceptance
Root Investigations for Development Applications
We help builders and planners by:
- Mapping roots before excavation or slab pours
- Advising on tree retention vs removal decisions
- Preventing costly project delays caused by incomplete council submissions
- Ensuring compliance with DA and CDC conditions
Frequently Asked Questions
Q1: How close can I build to an existing tree on my site?
Council rules protect trees within a Tree Protection Zone, our arborist can help calculate safe building distances for your project.
We measure TPZ and SRZ in line with AS 4970, providing clear CAD overlays and site maps for inclusion in your DA or CDC plans.
Q2: Do I need a root investigation before starting development or excavation?
Yes, if works are within a tree’s protection zone, our arborist can help confirm impacts before excavation begins.
We use AirSpade and subsurface mapping to expose and record roots, ensuring compliant design adjustments or barrier installation.
Q3: How can a root investigation help my DA or CDC get approved faster?
A Council-compliant root report reduces delays, our arborist can help deliver fast, accurate documentation for your submission.
We identify root constraints early, provide mitigation strategies, and prepare AS 4970-based reports that support faster council approval.
Q4: What if roots are found near proposed foundations or services?
Our arborist can help determine if they’re structural and recommend solutions that meet council and engineering standards.
We provide measured drawings, barrier options and retention advice so development proceeds safely without breaching protection zones.
Q5: Do I need Council approval to cut or install a root barrier near a tree?
Yes, if roots belong to a protected or retained tree, our arborist can help manage the full approval process.
We prepare detailed root impact assessments and barrier specifications for Northern Beaches Council compliance under AS 4970.
