Do you need an AIA in Cornwall?
If your proposal cannot avoid tree influence, Cornwall 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.
In Cornwall, Arboricultural Impact Assessments are often required where:
Residential schemes place development close to established trees
Edge-of-settlement growth intersects with hedgerows and tree belts
Regeneration land includes historic trees shaping site layout
Semi-rural plots introduce works within root protection areas
Tree retention is assessed alongside landscape character considerations.
Our Arboricultural Impact Assessments support projects in the wider Cornwall area, where layouts, access and retained trees interact.
Why Planning Authorities Require an AIA in Cornwall
Cornwall 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.

Cornwall planning officers typically require an AIA where construction may impact root protection areas.
Most Local Planning Authorities in Staffordshire require HMMPs to cover a minimum 30-year period, in line with statutory Biodiversity Net Gain obligations.
Rural housing, residential schemes, and redevelopment of larger plots frequently require AIAs in Cornwall.
