Do you need an AIA in Merseyside?
If your proposal cannot avoid tree influence, Merseyside 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 Merseyside, Arboricultural Impact Assessments are often required where:
Urban regeneration introduces development close to retained trees
Brownfield sites include established tree groups affecting layout
Edge-of-settlement growth intersects with tree-lined corridors
Residential schemes introduce construction within root protection zones
The emphasis is on realistic mitigation within constrained urban sites.
Our Arboricultural Impact Assessments support projects in Liverpool and the wider Merseyside area, where layouts, access and retained trees interact.
Why Planning Authorities Require an AIA in Merseyside
Merseyside 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.
