Do you need an AIA in Shropshire?
If your proposal cannot avoid tree influence, Shropshire 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.
Within Shropshire, Arboricultural Impact Assessments are frequently required where:
Residential development in Shrewsbury, Oswestry and Bridgnorth encroaches on mature garden or boundary trees
Edge-of-village schemes require new access tracks or services to cross retained tree groups
Brownfield regeneration sites include long-established tree belts shaping site constraints
Rural plots near market towns introduce foundations or drainage within root protection zones
Planning decisions focus on the compatibility between proposed layouts and the long-term health of retained trees.
Our Arboricultural Impact Assessments support projects in Telford, Shrewsbury and the wider Shropshire area, where layouts, access and retained trees interact.
Why Planning Authorities Require an AIA in Shropshire
Shropshire 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 Shropshire
Why are Arboricultural Impact Assessments important for developments in Shropshire?
Arboricultural Impact Assessments (AIAs) are important in Shropshire due to the county’s extensive rural landscape, mature tree cover, and frequent presence of hedgerows and woodland edges. An AIA ensures that development proposals properly account for these features, helping to balance site viability with the protection of valuable trees and landscape character.
When will a Local Planning Authority in Shropshire request an AIA?
An AIA is typically requested when trees are present within or adjacent to a development site and could be affected by construction. In Shropshire, this often applies to both rural and edge of settlement developments where trees form part of the wider landscape or ecological network.
What types of trees are considered within an Arboricultural Impact Assessment?
An AIA considers all trees that could be influenced by development, including individual trees, groups, hedgerows, and woodland areas. In Shropshire, hedgerows can be particularly important as they often contribute to biodiversity, boundary definition, and planning considerations.
How does an AIA deal with development near woodland or large tree groups?
Where development is proposed near woodland or established tree groups, the AIA will assess potential impacts such as shading, root disturbance, and construction pressure. In Shropshire, this is especially relevant on sites bordering agricultural land or rural estates, where tree belts are common.
Can an Arboricultural Impact Assessment help reduce planning objections?
Yes. A well prepared AIA provides clear evidence that tree related constraints have been identified and addressed. In Shropshire, this can reduce objections from planning officers, consultees, or local stakeholders by demonstrating a considered and responsible approach to tree retention and protection.
What role does BS5837 play in an AIA?
BS5837 is the British Standard that guides how trees should be assessed in relation to construction. In Shropshire, AIAs are expected to follow this standard, ensuring consistency in how trees are categorised, how Root Protection Areas are calculated, and how impacts are assessed within planning submissions.
How are access routes and site layouts influenced by an AIA?
An AIA will assess how access points, driveways, and building footprints interact with existing trees. In Shropshire developments, this often results in design adjustments such as repositioning access routes or reducing hardstanding within sensitive root zones to allow for tree retention.
What mitigation measures are typically recommended in an AIA?
Mitigation measures may include protective fencing, changes to construction methods, or design alterations to avoid tree damage. In Shropshire, recommendations may also consider long term landscape integration, ensuring retained trees continue to contribute to the character of the site.
Which Local Planning Authorities in Shropshire may require an AIA?
Local Planning Authorities across Shropshire will require an AIA where trees are a planning consideration. This includes Shropshire Council and Telford and Wrekin Council. Each authority sets its own validation requirements, so early engagement is recommended.
How early should an Arboricultural Impact Assessment be considered in Shropshire projects?
An AIA should be considered at the early design stage, once initial layout options are being explored. In Shropshire, early input helps ensure trees are integrated into the design rather than becoming a constraint later, reducing the risk of planning delays or costly redesign.
