Service area confirmed on enquiry.

Sorbus approach

Understand the tree constraints early.

Development work benefits from knowing what is present, what may be affected and what decisions need to be made before plans harden.

Sorbus approach

Connect the site information to the proposal.

Tree records, mapped locations, protection considerations and proposed works can be assembled into a clearer basis for discussion with the project team.

Sorbus approach

Keep calculations and judgement distinct.

Where AIA or encroachment calculations are required, they should be explained alongside the underlying site information and the responsible practitioner’s professional judgement.

Useful answers

Questions to ask
before the site visit.

What is an AIA?

An Arboricultural Impact Assessment considers how a proposal may affect trees and what protection or mitigation may be appropriate. The exact requirements depend on the project and approving authority.

Can you assess encroachment?

Encroachment can be assessed where the required tree and proposal information is available. The method and reporting scope should be agreed for the project.

Can you work with my existing plans?

Share the available site and proposal information during the enquiry so the appropriate assessment scope can be discussed.

Before the site visit

Make the brief clear.

Send the location, the question you need answered, and any available photographs, plans or previous reports. Agree the purpose and deliverables before arranging work.
