Arboricultural Impact Assessments and Tree Management Plans
- Address council requirements by evaluating tree health, lifespan, and retention values.
An Arboricultural Impact Assessment (AIA) evaluates the potential effects of a development project on existing trees and their surroundings. It helps clients understand:
- Tree Health: The condition and value of existing trees.
- Impact Analysis: How the development will affect trees, including removal or preservation.
- Mitigation Strategies: Recommendations for tree protection and Management Plan during and after construction.
- Compliance: Ensures adherence to local regulations regarding tree preservation. Overall, the AIA provides essential information for sustainable development planning while maintaining tree health and safety.
Our AQF Level 5 arborists specialise in navigating council regulations, meeting tight deadlines, and delivering timely, accurate reports to keep projects moving forward smoothly.
Frequently Asked Questions
When Arbor Express is preparing an Arboricultural Impact Assessment (AIA) Report for a development in NSW, the following key points are commonly considered:
What is the purpose of a Arboricultural Impact Assessment?
- Assess the impact of the proposed development on trees located on or near the site.
- Determine which trees can be retained and which may need removal.
- Ensure compliance with local council and state regulations, such as AS-4970-2009 (Protection of Trees on Development Sites).
What are the key components of a Arboricultural Impact Assessment?
- Tree Survey: Includes species, size, health, age, and significance of trees.
- Tree Protection Zones (TPZ): Establishes the area around retained trees that must be protected.
- Structural Root Zone (SRZ): Defines the minimum root area needed for the tree’s stability.
- Tree Condition Assessment: Evaluates the health, structural integrity, and lifespan of each tree.
- Impact Analysis: Assesses how construction activities (excavation, machinery, drainage changes) may affect trees.
- Retention and Removal Plan: Identifies trees to retain or remove based on their condition and development feasibility.
What is a Tree Protection Plan? (if required)
- Specifies methods to protect retained trees during construction, such as fencing, signage, and exclusion zones.
- Details measures to mitigate potential impacts, including root zone protection, pruning, and soil aeration.
- Arbor Express has over 30 years experience understanding Councils guidelines to address specific requirements outlined by the local council, as part of the Development Application (DA).
- Provide documentation to satisfy tree preservation orders (TPOs) or significant tree registers, if applicable.
Timeline and Deadlines (Fast track available for tight deadlines)
- Ensure the AIA report aligns with DA submission timelines to avoid project delays.
Professional Expertise / our team of consulting Arborists has Level 5 to a Level 9, the highest in Australia
- The report should be prepared by a minimum Level 5 Arborist to ensure accuracy and credibility.
Additional considerations for Arboricultural Impact Assessment
- Tree root investigations with mapping to allow developments to be located closer to trees
- Project Arborist will be required if trees are retained. We guarantee a Project Arborist for all AIA reports we do.
- Impact of Retained Trees that assess whether retained trees will pose long-term risks to structures or people.
- Replacement Planting. If tree removal is approved, provide recommendations for compensatory planting as required by council.
- An AIA report is essential for balancing development needs with environmental conservation and regulatory compliance.
