Industry Leading Standard
We stay with you from first call through to submission.Â
If your proposal cannot avoid tree influence, Somerset 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 Somerset, Arboricultural Impact Assessments are commonly required where:
Housing schemes encroach on mature trees near settlement edges
Infrastructure routes pass through retained tree groups
Regeneration land includes established trees affecting layout
Semi-rural development introduces foundations within root protection zones
Authorities assess long-term tree viability alongside development proposals.
Our Arboricultural Impact Assessments support projects in the wider Somerset area, where layouts, access and retained trees interact.
Somerset 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.
Our AIAs in Somerset are commercially aware, proportionate and planning-led, designed to support real-world construction sequencing, access logistics and foundation strategy without unnecessary escalation.
We resolve tree-related planning risk across Somerset through:
Defensible impact assessment aligned to BS 5837
Proportionate mitigation and construction guidance
Clear layout compatibility testing for planners
Integrated reporting with TPPs, drainage or ecology where required
Your application is strengthened with evidence that planners trust.
Assessment of site layout alongside tree survey data.
Root protection areas, canopy spread, access routes and construction zones are fully assessed.
Protection, construction methods and layout refinements defined.
Integrated with Tree Protection Plans (TPPs), drainage design or ecological surveys.

Arboricultural Impact Assessments are important in Somerset due to the county’s varied landscape, including the Somerset Levels, rural farmland, and historic settlements. Trees often provide structure in otherwise open environments, making their assessment essential within development proposals.
An AIA is required where trees are present on or near a development site and could be affected by construction. In Somerset, this commonly applies to residential developments, farm diversification projects, and sites where trees or hedgerows form part of the landscape.
In low lying and flood prone areas, trees can play an important role in stabilising soils and supporting drainage systems. An AIA assesses how development may affect these trees and ensures proposals do not negatively impact their function or long term health.
Trees in these environments may have shallow root systems or be sensitive to changes in water levels. An AIA evaluates these conditions and ensures development proposals account for potential impacts from drainage changes or ground disturbance.
Hedgerows and boundary trees are a key feature of Somerset’s landscape. An AIA assesses their condition, structure, and contribution to the site, helping to ensure they are retained and protected wherever possible.
Yes. On rural sites, an AIA ensures that tree related constraints are properly understood and addressed. In Somerset, this helps integrate development into the surrounding landscape while maintaining important natural features.
An AIA identifies where development may conflict with existing trees and provides recommendations to adjust layouts accordingly. In Somerset, this often helps retain key landscape features while allowing practical development to proceed.
Mitigation measures may include protective fencing, revised layouts, and construction techniques designed to reduce root disturbance. In Somerset, recommendations often reflect site specific conditions such as water levels, soil type, and open landscape exposure.
Local Planning Authorities across Somerset frequently require Arboricultural Impact Assessments where trees are present. This includes Somerset Council and Bath and North East Somerset Council. Validation requirements vary and should be reviewed early.
Carrying out an AIA early helps identify tree related constraints before designs are finalised. In Somerset, this supports better site planning, reduces planning risk, and ensures development proposals align with local planning expectations and environmental conditions.
