How Tree Root Investigations Can Save Your Melbourne Property Development Project
You plan a development in Melbourne. You face a hidden risk, tree roots under the soil. We advise an early root investigation. We use the term root investigation, because it flags a precise service. We link our work to practical outcomes for your project. Visit our homepage at https://www.arborplans.com.au/ to see case studies and contact details.
Why this matters in Melbourne, Victoria
You will work with local councils, engineers, and builders. Councils in Melbourne commonly request an arborist root report as part of planning permit submissions. You must protect your investment. You must avoid delays caused by unexpected root-related issues. Melbourne properties often host mature eucalypts, elms, and exotic species. These trees can have extensive root systems that affect foundations, drains, and landscaping.
What is a root investigation?
A root investigation focuses on where roots are, how large they are, and how they interact with proposed works. We inspect the site first. We combine visual assessment with targeted excavation, root mapping, and soil probes. We record root position and size. We recommend methods to protect roots or to remove roots when removal is the only practical option. We document findings in an arborist root report you can submit to councils and project teams.
How root investigation differs from a standard tree report
A standard tree assessment examines tree health, structure, and canopy. A root investigation examines below-ground structures. We measure root diameter, depth, and direction. We assess the root system in relation to foundations, pipes, and retaining walls. We test for previous root damage to structures. We include actionable steps you can follow on site during construction.
Key reasons to commission a root investigation early
Avoid delays: You can identify root risks before you start excavation. You can plan mitigation while you obtain permits. This reduces the likelihood of redesigns.
Meet council requirements: Many Melbourne councils require an arborist root report for site works near significant trees. We prepare reports that align with local planning policies.
Reduce repair costs: You can address root issues before they cause subsidence, pipe blockages, or pavement failure. Early action reduces repair scope.
Protect tree health: You can adapt design to keep trees that add value to your property. You can specify root protection zones and construction methods that limit root loss.
Common problems caused by Melbourne property tree roots
Foundation movement: Roots can alter soil moisture around footings. That change can cause movement. You should detect root influence before you pour footings.
Blocked drains and pipes: Roots can infiltrate joints and cause repeated blockages. A root investigation reveals where roots approach services.
Cracked paving and walls: Roots push up paths and thin retaining walls. You can plan repairs or preventative measures after a targeted assessment.
Reduced tree stability: Construction can sever critical roots. You can avoid unsafe removals with careful surveying.
How we perform a tree root damage assessment
We follow a structured process that aligns with Australian standards and local planning expectations. We take these steps:
Site briefing with you and the project team, so we understand scope and staging.
Visual inspection of trees, turf, and surface signs of root activity.
Non-destructive testing, including ground-penetrating radar where relevant, to map large roots without unnecessary excavation.
Targeted hand excavation to expose root systems at key locations. We avoid heavy excavation that damages roots.
Measurement and photographic records of roots and affected structures.
Assessment of soil moisture and compaction near foundations and services.
Preparation of an arborist root report that contains maps, photos, and clear recommendations.
Each step uses clear methods. We keep records you can use for permit applications and contractor briefs.
What you will find in an arborist root report
Site description and tree inventory, including species and size.
Root maps showing location, depth, and diameter of roots near proposed works.
Evaluation of root influence on structures and services.
Tree retention advice and root protection zone specifications.
Recommended construction protocols to protect roots during works, including trenching methods, piling options, and irrigation changes.
Where removal is necessary, a staged approach to minimise impact.
How a root investigation influences design and construction
You can use an arborist root report to change design early. You can shift a footing, extend a pier, or adjust service routes to avoid major roots. You can instruct builders to use root-sensitive excavation techniques. You can choose construction methods that cause less disturbance, such as bored piling or cantilevered footings. All interventions rely on accurate root data from a root investigation.
Case example, simplified and localised
We inspected a terrace redevelopment in inner Melbourne. The site had a mature street tree with a canopy that overhung the property. Builders planned a basement. We conducted a root investigation. We found major roots near the proposed excavation trench. We produced an arborist root report that proposed a redesigned basement perimeter and a piling solution. The project team adjusted the design and completed construction while keeping the street tree. The client avoided council objections and reduced rework.
Practical advice for developers and homeowners
Commission a root investigation when trees grow within twice the canopy radius of proposed works.
Include an arborist root report in your planning permit package when local policy refers to significant trees.
Instruct contractors to follow the root protection zone specifications in the arborist root report.
Use hand excavation within root zones where planners expect minimal damage.
Maintain even soil moisture during construction to reduce root stress.
Costs and timing considerations
You should allow time for a root investigation early in the design phase. We schedule assessments to fit your planning timetable. Early investigation can reduce risks that add time and cost later. We prepare reports that councils accept and that engineers can use to finalise design.
How we balance tree retention with site use
We assess tree value in terms of landscape, amenity, and planning criteria. We propose solutions that protect high-value trees while enabling development. Where removal provides the best outcome for safety and design, we propose staged removal and replacement planting plans that align with council expectations.

Frequently asked questions
Q: When should I commission an arborist root report?
A: Commission the report during concept design, before you finalise footings or services. Early action gives you options.
Q: Will an investigation require removing trees?
A: We avoid removals when possible. We recommend protective measures first. We propose removal only when safety or design requires it.
Q: Can an arborist root report satisfy council conditions?
A: We prepare reports that align with Melbourne council planning requirements. Councils accept clear, documented findings and mitigation strategies.
