Preliminary Arboricultural Impact Assessment Reports for Developments / Tree Reports Removals

At Arbor Express, we conduct comprehensive assessments of trees to determine if they should be retained or removed for the development. If retention is needed, we ensure compliance with AS-4970-2009 (Protection of Trees on Development Sites).

At the Planning and Pre-Design stage of a project a Preliminary Arboricultural Impact Assessment is prepared by a Level 5 Arborist.

By providing a Preliminary Arborist Report, we equip developers and architects with crucial information about potential design limitations imposed by existing trees. This proactive approach helps prevent wasted time and resources on architectural designs that may be infeasible due to the need to protect specific trees.

Preliminary Arboricultural Assessment Report

A preliminary tree assessment is performed at the pre-design stage, following the accurate plotting of existing trees on a survey map.

Goals of the report:

  • Identify design opportunities and constraints
  • Evaluate tree retention values
  • Determine Tree Protection Zones (TPZ) and Structural Root Zones (SRZ)

Information to collect for each tree:

  • Tree number
  • Botanical name
  • Height and canopy spread
  • Vigour and structure
  • Age class
  • Significance and estimated lifespan
  • Heritage and cultural considerations
  • Ecological and habitat factors
  • Function (Eg: screening or feature tree)
  • Additional details such as surface roots, trunk diameter at breast height (DBH), TPZ, and SRZ.

The information in the report is utilised by planners, architects, and designers to ensure compliance with planning regulations. They leverage this data to design layouts that provide adequate space for trees selected for retention, ensuring their viability moving forward.

By choosing Arbor Express, you can trust that your projects tree management needs will be handled professionally and efficiently, protecting both the environment and your development objectives.
