What is an Arboricultural Impact Assessment (AIA)?
An Arboricultural Impact Assessment (AIA) is a crucial component of the planning and development process, designed to evaluate the potential effects of proposed construction on existing trees within or near a development site. This assessment is often required by local planning authorities as part of a Tree Protection Plan (TPP) and helps developers understand how to integrate trees into their designs responsibly.

Conducting an Arboricultural Impact Assessment provides multiple benefits for developers, landowners, and the environment. Some key reasons why an AIA is essential include:
1. Planning Approval Compliance – Many local authorities require an AIA to ensure that proposed developments consider tree conservation.
2. Environmental Protection – Trees play a crucial role in carbon sequestration, biodiversity, and climate regulation. An AIA helps protect these vital ecological assets.
3. Legal Requirements – Certain trees may be protected under Tree Preservation Orders (TPOs) or be located in Conservation Areas, necessitating careful planning before any development.
4. Sustainable Development – An AIA helps balance urban expansion with environmental sustainability, promoting green infrastructure within developments.
5. Avoiding Costly Delays – Identifying tree-related constraints early in the planning process can prevent unexpected project delays and additional costs.
Our Arboricultural Impact Assessment Process
At Gradwell Ecology, our Arboricultural Impact Assessment (AIA) process is designed to provide a thorough evaluation of how proposed developments interact with existing trees, ensuring compliance with regulatory standards while promoting sustainable land use.
Our approach begins with an initial consultation and site survey, where we assess tree health, species, and potential risks. We then conduct a detailed analysis of potential impacts, considering factors such as root protection, canopy interference, and soil conditions. Based on our findings, we develop tailored mitigation strategies, including protective measures, alternative construction techniques, and tree retention plans. Our final AIA report provides comprehensive recommendations and a Tree Protection Plan (TPP) to help developers navigate planning requirements efficiently. Throughout the project, we offer ongoing support to ensure that tree conservation remains a key priority in your development.
