Do you need an AIA in Nottinghamshire?
If your proposal cannot avoid tree influence, Nottinghamshire planners will expect a formal Arboricultural Impact Assessment to validate the application.
If you’re a homeowner, you may need an AIA when an extension, driveway or garage sits close to retained trees or their roots.
If you’re a developer, an AIA is typically required where layouts, access routes, drainage or foundation designs interact with existing trees shown on a BS 5837 tree survey.
Across Nottinghamshire, Arboricultural Impact Assessments are commonly triggered where:
Housing schemes in Nottingham, West Bridgford and Mansfield bring new structures or access routes close to established boundary trees
Expansion at settlement edges around Newark, Worksop and Hucknall requires infrastructure to pass through retained tree belts
Redevelopment of former colliery and industrial sites includes mature trees that now influence site layout
Semi-rural plots near Southwell and surrounding villages place foundations or services within root protection areas
In these scenarios, local authorities consider whether retained trees can realistically be protected over the lifetime of the development.
Our Arboricultural Impact Assessments support projects in Nottingham, Newark-on-Trent and the wider Nottinghamshire area, where layouts, access and retained trees interact.
Why Planning Authorities Require an AIA in Nottinghamshire
Nottinghamshire planning authorities request Arboricultural Impact Assessments where development proposals interact directly with retained trees. LPAs use AIAs to test whether layouts, access routes, drainage strategies and foundation designs respond realistically to canopy spread and root protection areas, in line with BS 5837 and the National Planning Policy Framework. Where impacts are unclear or poorly justified, applications are commonly delayed, conditioned or returned for redesign.

FAQ - AIA in Nottinghamshire
When is an Arboricultural Impact Assessment required for planning in Nottinghamshire?
An Arboricultural Impact Assessment (AIA) is required where trees could be affected by a proposed development. In Nottinghamshire, Local Planning Authorities will typically request an AIA when trees are within influencing distance of construction works, particularly where layout, access, or ground disturbance may impact root systems or canopy spread.
What does an Arboricultural Impact Assessment actually assess?
An AIA examines how a development proposal interacts with existing trees, including potential conflicts with foundations, service routes, access points, and changes in ground levels. It identifies which trees can be retained, which may require removal, and what mitigation measures are needed to protect retained trees.
Is an AIA a mandatory requirement for all developments in Nottinghamshire?
Not all developments require an AIA, but it becomes necessary where trees are present and could be impacted. In Nottinghamshire, planning validation requirements vary between authorities, but where trees are a material consideration, an AIA is often essential to support a planning application.
How does an Arboricultural Impact Assessment support planning approval?
An AIA provides clear evidence that trees have been properly considered within the design process. In Nottinghamshire, this helps planning officers assess whether the development complies with local policy, reduces risk to important trees, and demonstrates that appropriate protection measures will be implemented.
What is the difference between an Arboricultural Impact Assessment and an Arboricultural Method Statement?
An Arboricultural Impact Assessment evaluates the impact of a proposed development on trees, while an Arboricultural Method Statement (AMS) sets out how trees will be protected during construction. In Nottinghamshire projects, the AIA often informs the need for an AMS, particularly where works occur near retained trees.
Can an AIA influence the design of a development?
Yes. An AIA is often used to refine site layouts by identifying constraints early in the design process. In Nottinghamshire, this can lead to repositioning buildings, adjusting access routes, or altering foundation designs to retain valuable trees and reduce planning risk.
What happens if development encroaches into a tree’s Root Protection Area?
Where development proposals encroach into a Root Protection Area (RPA), the AIA will assess the level of impact and whether it can be mitigated. In Nottinghamshire, solutions may include specialist foundation designs or construction techniques, but unacceptable impacts may require design changes or tree removal justification.
Are protected trees treated differently within an AIA?
Yes. Trees subject to Tree Preservation Orders or located within Conservation Areas are given additional consideration. In Nottinghamshire, the AIA must clearly demonstrate how these trees will be protected, and any proposed works will require formal consent from the relevant Local Planning Authority.
Which Local Planning Authorities in Nottinghamshire may request an AIA?
Local Planning Authorities across Nottinghamshire commonly require an AIA where trees are present. This includes authorities such as Nottingham City Council, Broxtowe Borough Council, and Gedling Borough Council. Each authority has its own validation checklist, so requirements should be confirmed early in the planning process.
At what stage should an Arboricultural Impact Assessment be completed?
An AIA should be prepared once a development layout has been drafted but before submitting a planning application. In Nottinghamshire, early assessment allows tree related constraints to be addressed proactively, reducing the likelihood of planning delays or redesign requirements.
