When do I need an Arboricultural Impact Assessment?

An Arboricultural Impact Assessment (AIA) is a written assessment which determines the site specific effect of a planned development on the existing tree stock.

It is a recommendation of the British Standard 5837: 2012 Trees in relation to design, demolition & construction - Recommendations, that an Arboricultural Impact Assessment is produced in order to inform the development process.

The Arboricultural Impact Assessment identifies trees to be removed and those to be retained and it highlights the potential conflicts between retained trees and the planned development. Typical conflicts between trees and developments can range from crown shading issues of a tree, to a planned development breaching a trees’ Root Protection Area (RPA).

Additionally, The Arboricultural Impact Assessment also considers the impact of statutory designations such as tree preservation orders (TPO’s), and identifies the long term value and benefits of trees in the urban and built environment.
