BS5837 Arboricultural Impact Assessment (AIA)

Secure your planning permission with an expert AIA. We bridge the gap between initial design and final construction, justifying your project to Local Planning Authorities.

Where the AIA Fits In

The Arboricultural Impact Assessment is a critical stage in the planning chain. It bridges the gap between the initial survey and the final construction plan. By following this chain, we ensure your application in Surrey, Sussex, or London is robust and defensible. The planning process typically follows this professional sequence: 1. BS 5837 Tree Survey & Report; 2. Tree Constraints Plan (TCP); 3. Arboricultural Impact Assessment (AIA); 4. Tree Protection Plan (TPP) & Method Statement (AMS).

Why do you need it? The assessment identifies any potential conflict between retained trees and project plans. It ensures crucial aspects, such as Tree Preservation Orders (TPO) and Conservation Areas, are protected. We identify the long-term value of your trees, working to secure their health and safety within the built environment. A substantial body of research supports the economic, environmental, and social benefits that trees bring to urban areas and the contributions they make to people’s quality of life and sense of wellbeing.

BSI Technical Recommendations

Following the BSI guidelines, we identify obstacles to root development and account for past ground disturbances. This level of technical scrutiny ensures your planning application stands up to the most rigorous council inspections across the Southeast.
