Do you need an AIA in Cheshire?
If your proposal cannot avoid tree influence, Cheshire 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 Cheshire, Arboricultural Impact Assessments are typically required where:
Residential schemes bring buildings and driveways close to mature boundary trees
Edge-of-settlement growth requires access infrastructure through retained tree belts
Former industrial or estate land includes long-established trees affecting layout
Semi-rural developments introduce foundations within root protection areas
Planning officers assess the balance between development form and sustainable tree retention.
Our Arboricultural Impact Assessments support projects in Warrington, Chester, Crewe, Macclesfield and the wider Cheshire area, where layouts, access and retained trees interact.
Why Planning Authorities Require an AIA in Cheshire
Cheshire 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.
