What an AIA does

Assess the design against the trees

The exact analysis is matched to the proposed layout, tree survey information and planning requirement.

Tree Retention & Removal

The proposed layout is reviewed against the surveyed trees to identify likely retention and removal implications.

Retained-tree relationships Potential tree removals Design conflicts identified Planning implications explained clearly

Root Protection Area Impacts

Root Protection Areas and relevant below-ground constraints are considered against the proposed development.

Building footprints Access and hard-surface interactions Level / excavation considerations where relevant Areas needing design attention

Crown & Layout Relationships

The design is considered in relation to existing crowns, likely spatial relationships and the practical use of the proposed development.

Crown spread relationships Building proximity Future tree / development interaction Layout issues highlighted for the project team

Planning-Focused AIA Report

The assessment brings the relevant tree and design information together into a clear professional report for the planning process.

Quick answers

Arboricultural Impact Assessment FAQs

What is an Arboricultural Impact Assessment (AIA)?

An Arboricultural Impact Assessment reviews how a proposed development may affect existing trees. It considers the proposed layout alongside tree survey information, canopy constraints, Root Protection Areas and other relevant arboricultural factors.

When is an AIA needed for planning?

An AIA is commonly required where trees are present on or close to a development site and the planning authority needs to understand the likely arboricultural effects of the proposal. The exact requirement depends on the site, drawings and council wording.

What should I send for an AIA quote?

Send the site postcode, the latest proposed layout or planning drawings, any council or tree officer wording and any existing BS5837 tree survey or tree schedule you already have. If you are missing something, send what you have and we can define the next step.

Can you prepare an AIA if I already have a BS5837 tree survey?

Often, yes. We can review the existing survey information alongside the current design drawings and confirm whether it is suitable for the AIA scope.

What does an AIA assess?

The assessment can consider tree retention and removal implications, Root Protection Areas, crown relationships, proposed buildings, access, level changes and other design interactions relevant to the agreed planning scope.

Is an AIA the same as a tree survey?

No. The tree survey records the trees and their relevant characteristics. The AIA uses the survey information together with the proposed design to assess the likely effects of development on the trees.

Will an AIA guarantee planning approval?

No. The AIA is prepared to support the planning process and council review. The local planning authority makes the planning decision.

How quickly can an AIA be prepared?

Timing depends on the availability and suitability of the tree survey, the latest design drawings, site complexity, whether additional site work is needed and current workload. The quote response will confirm the likely programme for the agreed scope.

Have the proposed layout?

Send it over. We’ll scope the AIA.

Plans + postcode + tree survey / council wording if available. That is enough to start.
