Tree Risk in Commercial Sites Is a Safety and Liability Issue

For commercial and industrial property managers, trees are rarely the focus of day-to-day operations — until something goes wrong.

Car parks, loading zones, pedestrian walkways, and building access points place vehicles, staff, tenants, and visitors beneath trees every day. When failures occur, the consequences are not just physical damage, but operational disruption and liability exposure.

This checklist is designed to help property managers identify when professional arborist assessment is required.

Why These Areas Require Priority Attention

Car parks and walkways combine:

• high foot and vehicle traffic
• fixed infrastructure
• predictable occupancy patterns
• elevated liability exposure

Even minor branch failures in these zones can result in:

• vehicle damage
• personal injury claims
• site access restrictions
• reputational impact

Car Park and Walkway Risk Checklist

Professional arborist review is recommended if any of the following are present.

Structural Indicators

• Leaning trees near parking bays
• Large horizontal limbs over vehicles
• Weak branch unions
• Past storm damage or corrective pruning

Canopy and Branch Condition

• Deadwood above traffic areas
• Hanging or fractured limbs
• Dense, overextended canopies
• Uneven growth following past pruning

Root Zone and Ground Conditions

• Cracked or heaving asphalt or concrete
• Exposed roots in traffic zones
• Drainage changes or water pooling
• Evidence of root damage from construction

Proximity Risks

• Trees overhanging buildings or awnings
• Branches near lighting, signage, or power
• Limited clearance for emergency access

Common Commercial Property Assumptions That Increase Risk

• “The tree has never caused a problem”
• “Storms are the only real risk”
• “Pruning will fix it”
• “Tree issues are low priority compared to building assets”

In practice, unmanaged tree risk often intersects directly with WHS and insurance obligations.

Why Reactive Management Costs More

Emergency responses typically involve:

• higher contractor costs
• limited scheduling options
• tenant disruption
• rushed decision-making

Proactive assessment allows work to be planned around:

• tenancy schedules
• access requirements
• budget cycles

Sensible Next Step

If trees are located near car parks, walkways, or access points, a professional arborist assessment can clarify risk and support informed management decisions.
