Tree mitigation advice that ensures a smooth progression through the planning and development process

An arboricultural impact assessment (AIA) is a written assessment that determines the site-specific effect of planned development on the existing tree stock. It is a recommendation of the British Standard (BS) 5837: 2012.

“Trees in relation to design, demolition and construction – Recommendations, that an Arboricultural Impact Assessment is produced in order to inform the development process.”

The AIA identifies trees to be removed and those to be retained. 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.

Additionally, an AIA also considers the impact of statutory designations such as tree preservation orders and identifies the long-term value and benefits of trees in the urban and built environment.
