Do you need an AIA in Wales?

If your proposal cannot avoid tree influence, Wales 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 Wales, Arboricultural Impact Assessments are typically needed where:

  • Residential growth in towns and suburbs brings buildings and parking areas close to existing trees

  • Infrastructure works at settlement edges intersect with established woodland or shelterbelts

  • Redevelopment of former industrial land incorporates mature trees that now define site structure

  • Semi-rural housing places services or soakaways within root protection areas

Welsh planning authorities assess whether tree retention is achievable alongside proposed development pressures.

Our Arboricultural Impact Assessments support projects in Wrexham, Swansea and the wider Wales area, where layouts, access and retained trees interact.

Why Planning Authorities Require an AIA in Wales

Wales 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.

Local Case Insight

A residential scheme in Wales proposed building extensions close to a retained tree group along the plot boundary. The original layout encroached into multiple root protection areas and conflicted with access arrangements. A targeted AIA reviewed constraints, refined layout positioning and adjusted construction methodology. The revised proposals were accepted without tree-related planning conditions.

FAQ - AIA in Wales

When is an Arboricultural Impact Assessment required for developments in Wales?

An Arboricultural Impact Assessment (AIA) is required where trees may be affected by a proposed development. In Wales, this typically applies where trees are located within or near the development footprint, particularly where planning applications must demonstrate consideration of environmental and landscape impacts in line with national and local policy.

Speak to Our Team

In Wales, planning decisions are guided by national policy such as Planning Policy Wales, alongside local development plans. An AIA supports these requirements by ensuring that trees, woodland, and green infrastructure are properly considered within development proposals, helping to demonstrate sustainable design.

Check My Site

AIAs are commonly required on a wide range of sites, including residential developments, rural conversions, and schemes affecting woodland or hedgerows. In Wales, developments in sensitive landscapes or near protected environments are more likely to require detailed arboricultural input.

Secure Survey

An AIA evaluates individual trees, groups, and hedgerows that may be impacted by development. In Wales, hedgerows are often an important feature of the landscape and biodiversity network, so their retention and protection are carefully considered within the assessment.

Yes. An AIA contributes to sustainable development by identifying opportunities to retain and integrate trees within a site layout. In Wales, this aligns with planning priorities that emphasise green infrastructure, biodiversity, and long term environmental resilience.

What happens if development proposals conflict with important trees?

Where conflicts arise, the AIA will assess the level of impact and explore mitigation options. In Wales, this may involve adjusting the layout, using alternative construction methods, or justifying any necessary tree removal in line with planning policy and environmental considerations.

Secure Survey

Yes. Trees protected by Tree Preservation Orders or located within Conservation Areas require additional assessment. In Wales, any proposed works affecting protected trees must be clearly justified within the AIA and approved by the relevant Local Planning Authority.

Request Survey Quote

Root Protection Areas (RPAs) define the area around a tree that should remain undisturbed. In Wales, RPAs are a key consideration within an AIA, influencing building positions, access routes, and construction methods to ensure that retained trees remain viable.

Check My Site

Local Planning Authorities across Wales may require an Arboricultural Impact Assessment where trees are a material consideration. This includes authorities such as Cardiff Council, Swansea Council, and Gwynedd Council. Validation requirements vary, so early engagement with the relevant authority is recommended.

An AIA should be carried out once a development layout has been prepared but before submitting a planning application. In Wales, early assessment helps ensure that tree constraints are addressed within the design, supporting a smoother planning process and reducing the risk of delays.

FAQ - AIA in Sussex

Why are Arboricultural Impact Assessments particularly important in Sussex developments?

Arboricultural Impact Assessments are especially important in Sussex due to the mix of coastal environments, historic towns, and heavily constrained urban areas. Trees often form part of established landscapes or conservation settings, meaning development proposals must carefully consider their retention and long term protection.

Speak to Our Team

Yes, where trees are present. In coastal parts of Sussex, trees may be subject to additional environmental pressures such as wind exposure and soil conditions. An AIA ensures these factors are considered alongside development impacts, helping to maintain tree health and site stability.

Check My Site

Within Conservation Areas, trees contribute significantly to local character. An AIA helps demonstrate how development proposals will preserve or enhance this character by assessing tree retention, potential impacts, and appropriate mitigation measures in line with planning expectations.

Common challenges include limited space, proximity to existing structures, and interactions with underground services. In Sussex, these constraints are often intensified in urban or suburban locations, requiring careful assessment within an AIA to avoid damage to retained trees.

Yes. By identifying tree constraints early, an AIA can help inform more efficient site layouts. In Sussex, this often allows developers to balance tree retention with practical design, ensuring the site is used effectively while remaining compliant with planning requirements.

How are trees prioritised for retention in an AIA?

Trees are assessed based on their condition, value, and contribution to the site and surrounding area. In Sussex, particular emphasis may be placed on mature or visually prominent trees, especially those that contribute to streetscapes or local character.

Secure Survey

Where risks are identified, the AIA will recommend mitigation measures such as protective fencing, revised layouts, or alternative construction methods. In Sussex, planning authorities expect clear justification where impacts cannot be avoided.

Request Survey Quote

Changes in ground levels can significantly affect tree roots. An AIA will assess these impacts and recommend suitable design or construction solutions. In Sussex, this is particularly relevant on sloping sites or developments involving terracing or regrading.

Local Planning Authorities across Sussex regularly require Arboricultural Impact Assessments where trees are present. This includes West Sussex County Council, East Sussex County Council, and Brighton and Hove City Council. Each authority has specific validation requirements that should be reviewed early in the process.

Early arboricultural input allows tree related constraints to be identified before designs are finalised. In Sussex, this helps avoid conflicts later in the planning process, reduces the need for redesign, and supports smoother progression through planning validation and approval stages.

FAQ - AIA in Bristol

Why are Arboricultural Impact Assessments critical for developments in Bristol?

Arboricultural Impact Assessments are particularly important in Bristol due to the city’s dense urban environment and strong planning emphasis on green infrastructure. Trees often form part of streetscapes, public spaces, and redevelopment sites, meaning their retention and protection are a key consideration in planning decisions.

Speak to Our Team

An AIA is typically required where trees are located within or adjacent to a development site and could be affected by construction. In Bristol, this is common for infill developments, redevelopment schemes, and projects involving changes to access, levels, or building footprints.

Check My Site

An AIA helps ensure that trees are integrated into regeneration schemes rather than removed unnecessarily. In Bristol, this supports planning objectives around urban greening, climate resilience, and improving the quality of the built environment.

Secure Survey

On constrained sites, trees may limit available space for development, affect foundation design, or conflict with underground services. In Bristol, these challenges are often addressed through careful design and technical solutions identified within the AIA.

Yes. An AIA provides clear, evidence based information that can support discussions with planning officers. In Bristol, this can help justify design decisions, tree removals where necessary, and proposed mitigation strategies.

How are street trees considered within an AIA in Bristol?

Street trees are an important part of Bristol’s urban environment and are often protected or highly valued. An AIA will assess potential impacts on these trees, including those located within highways or adjacent land, and recommend measures to protect them where possible.

Secure Survey

Where trees within public spaces are affected, the AIA will assess the level of impact and propose appropriate mitigation. In Bristol, this may include redesign, replacement planting, or coordination with the Local Planning Authority and other stakeholders.

Request Survey Quote

An AIA considers the interaction between tree roots and underground services. In Bristol, where infrastructure is often complex, this can influence layout design, foundation solutions, and construction methods to reduce conflicts and protect retained trees.

Speak to Our Team

In Bristol, Arboricultural Impact Assessments are typically required by Bristol City Council where trees are affected by development proposals. The council’s validation requirements and planning policies place strong emphasis on tree retention and urban greening.

Early assessment allows tree related constraints to be identified before designs are finalised. In Bristol, this helps developers avoid planning delays, reduce the need for redesign, and ensure proposals align with local policy expectations from the outset.

FAQ - AIA in Cheshire

Why are Arboricultural Impact Assessments important for developments in Cheshire?

Arboricultural Impact Assessments are particularly important in Cheshire due to the presence of mature trees, historic parkland, and high value residential settings. Development proposals often need to demonstrate that tree cover and landscape character are being carefully considered and protected.

Speak to Our Team

An AIA is typically required where trees are located within or close to a development site and may be affected by construction. In Cheshire, this commonly applies to residential developments, rural conversions, and sites where trees contribute to setting or screening.

Check My Site

On rural and semi rural sites, trees often form part of field boundaries, access routes, or wider landscapes. An AIA ensures these features are properly assessed, helping to integrate development into its surroundings while minimising impact on existing tree cover.

Trees are often a key factor in planning decisions, particularly where they contribute to local character or visual amenity. In Cheshire, retaining established trees can enhance the overall quality of a development and support approval by demonstrating a sensitive design approach.

An AIA identifies tree related constraints and provides guidance on how they can be managed. In Cheshire, this often involves adjusting layouts, retaining key trees, and ensuring development proposals make efficient use of available space without compromising important landscape features.

What happens if trees are located along site boundaries or access points?

Trees along boundaries or near access points can influence site layout and design. An AIA will assess potential impacts and recommend solutions, such as adjusting access positions or implementing protective measures, to allow development while safeguarding retained trees.

Secure Survey

New access routes can affect tree roots and soil conditions. An AIA evaluates these impacts and may recommend alternative designs or construction methods. In Cheshire, this is particularly relevant for developments involving long driveways or rural access tracks.

Request Survey Quote

Yes. Hedgerows are often assessed alongside trees, particularly where they form part of boundaries or contribute to the landscape. In Cheshire, hedgerows can be an important planning consideration and may influence development design and mitigation strategies.

Local Planning Authorities across Cheshire regularly require Arboricultural Impact Assessments where trees are present. This includes Cheshire East Council and Cheshire West and Chester Council. Each authority has its own validation requirements, so these should be reviewed early in the planning process.

Carrying out an AIA early allows tree related constraints to be identified before designs are finalised. In Cheshire, this supports better site planning, reduces the risk of planning delays, and helps ensure development proposals align with local expectations and landscape character.

FAQ - AIA in the West Midlands

Why are Arboricultural Impact Assessments essential for developments in the West Midlands?

Arboricultural Impact Assessments are essential in the West Midlands due to the region’s high level of urban development and infrastructure projects. Trees are often located within constrained sites, making it critical to assess how construction will affect their health, stability, and long term retention.

Speak to Our Team

An AIA is required where trees are present on or near a development site and could be impacted by proposed works. In the West Midlands, this frequently applies to residential developments, commercial schemes, and projects involving site clearance or redevelopment.

Check My Site

For larger developments, an AIA provides a structured assessment of tree constraints across the site. In the West Midlands, this helps guide masterplanning, ensuring that tree retention and green infrastructure are integrated into the overall development strategy.

Common constraints include limited space, proximity to existing buildings, and interactions with utilities or transport infrastructure. An AIA identifies these issues early, helping to inform practical design solutions that reduce conflict between development and existing trees.

An AIA supports sustainable development by promoting the retention of trees and integration of green infrastructure. In the West Midlands, this aligns with planning priorities focused on improving air quality, biodiversity, and the overall quality of urban environments.

Can an Arboricultural Impact Assessment influence planning outcomes?

Yes. A well prepared AIA provides clear evidence that trees have been properly considered, which can support planning approval. In the West Midlands, failure to address tree impacts can lead to planning delays, additional information requests, or refusal.

Secure Survey

An AIA identifies potential construction impacts such as root disturbance, soil compaction, and changes in ground levels. It then outlines mitigation measures, which may be developed further within an Arboricultural Method Statement to ensure trees are protected during construction.

Request Survey Quote

Trees contribute to the visual quality and environmental performance of redevelopment sites. In the West Midlands, retaining trees within regeneration projects can enhance site value, improve amenity, and support planning objectives related to green infrastructure.

Local Planning Authorities across the West Midlands commonly require Arboricultural Impact Assessments where trees are present. This includes Birmingham City Council, Coventry City Council, and Wolverhampton City Council. Each authority has specific validation requirements that should be reviewed before submission.

An AIA should be carried out once a development layout has been prepared but before a planning application is submitted. In the West Midlands, early assessment helps identify constraints, inform design decisions, and reduce the risk of delays during the planning process.

FAQ - AIA in Derbyshire

Why are Arboricultural Impact Assessments particularly relevant in Derbyshire?

Arboricultural Impact Assessments are highly relevant in Derbyshire due to the county’s varied landscape, including upland areas, valleys, and established tree cover around settlements. Development proposals must carefully consider how trees contribute to landscape character and how they may be affected by changes in land use.

Speak to Our Team

An AIA is typically required where trees are present within or near a development site and could be impacted by construction. In Derbyshire, this often applies to developments on sloping sites, edge of settlement locations, or areas where trees form part of the surrounding landscape.

Check My Site

Topography plays a key role in Derbyshire developments. Changes in levels, cut and fill operations, and drainage design can all affect tree roots and stability. An AIA assesses these factors to ensure that development proposals do not compromise retained trees.

Yes. Sites located near or within the setting of the Peak District may require more detailed assessment due to the sensitivity of the landscape. In Derbyshire, an AIA helps demonstrate that trees and landscape features are being protected in line with planning expectations.

Trees on sloping sites can be more sensitive to ground disturbance and changes in drainage. An AIA evaluates these risks and recommends appropriate design and construction measures to maintain tree stability and health.

What impact do access routes have on trees in Derbyshire developments?

Access routes, particularly on rural or constrained sites, can have a significant impact on tree roots. An AIA will assess the proposed access design and recommend adjustments or construction methods to minimise damage to retained trees.

Secure Survey

In smaller settlements, trees often contribute to local character and visual amenity. An AIA ensures that these trees are considered within the design process, helping to retain key features that define the setting of villages and market towns in Derbyshire.

Request Survey Quote

Mitigation measures may include protective fencing, revised layouts, or specific construction techniques to reduce root disturbance. In Derbyshire, recommendations often reflect site specific challenges such as slope, access, and proximity to existing vegetation.

Local Planning Authorities across Derbyshire frequently require Arboricultural Impact Assessments where trees are present. This includes Derbyshire County Council, Derby City Council, and High Peak Borough Council. Validation requirements vary, so these should be confirmed early in the planning process.

Carrying out an AIA early helps identify tree related constraints before designs are finalised. In Derbyshire, this allows for better integration of development within the landscape, reduces planning risk, and supports a smoother application process.

Do you need an AIA in Warwickshire?

If your proposal cannot avoid tree influence, Warwickshire 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 Warwickshire, Arboricultural Impact Assessments are commonly needed where:

  • Residential infill places development close to established trees

  • Edge-of-settlement growth requires access roads through tree-lined boundaries

  • Regeneration sites include historic tree groups shaping layout

  • Semi-rural housing introduces works within root protection areas

Planners assess whether proposed layouts respect arboricultural constraints.

Our Arboricultural Impact Assessments support projects in Nuneaton, Rugby, Royal Leamington Spa, Warwick, Stratford-upon-Avon, Bedworth and the wider Warwickshire area, where layouts, access and retained trees interact.

Why Planning Authorities Require an AIA in Warwickshire

Warwickshire 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.

Local Case Insight

A residential scheme in Warwickshire proposed rear extensions close to retained boundary trees. The original layout conflicted with root protection areas and proposed access routes. A proportionate AIA refined layout design and construction sequencing. The amended scheme validated without tree-related conditions.

FAQ - AIA in Warwickshire

Why are Arboricultural Impact Assessments important for developments in Warwickshire?

Arboricultural Impact Assessments are important in Warwickshire because many development sites sit within established landscapes shaped by mature trees, hedgerows, and historic settlement patterns. An AIA helps show that proposed works have properly considered these features and their role in local character.

Speak to Our Team

An AIA is usually required where trees are present on or close to a development site and may be affected by construction. In Warwickshire, this often includes housing schemes, rural conversions, edge of village sites, and developments where existing trees contribute to screening or visual amenity.

Check My Site

On sites near historic settlements, trees often play an important role in setting, approach views, and boundary structure. An AIA assesses how development may affect those trees and helps ensure the design responds appropriately to the existing landscape framework.

Yes. In Warwickshire, boundary trees and hedgerow trees are often a key part of the site’s visual and ecological structure. An AIA considers their condition, value, and likely sensitivity to development so they can be properly factored into the planning and design process.

An AIA can influence the layout by identifying where buildings, access routes, parking areas, and service runs may conflict with retained trees. In Warwickshire, this often helps shape more responsive designs that work with the site rather than forcing development into sensitive areas.

What happens if a proposed driveway or access point affects existing trees?

If an access point affects existing trees, the AIA will assess the likely impact on roots, canopy, and long term retention. In Warwickshire, this is particularly relevant on residential and rural sites where mature frontage trees or roadside boundaries are common.

Secure Survey

Yes. An AIA is a useful way to identify trees that make an important contribution to the wider setting of a site. In Warwickshire, this can include trees that frame rural views, define field boundaries, or soften the edge between settlement and open countryside.

Request Survey Quote

Mitigation measures may include protective fencing, revised layouts, special construction methods, or changes to groundworks near retained trees. In Warwickshire, the recommendations often focus on preserving established landscape features while allowing practical development to proceed.

Local Planning Authorities across Warwickshire may require an Arboricultural Impact Assessment where trees are a material planning consideration. This includes Warwick District Council, Stratford on Avon District Council, and Nuneaton and Bedworth Borough Council. Validation requirements can vary, so they should be checked at an early stage.

An AIA should be prepared once an initial development layout has been drawn up but before the planning application is submitted. In Warwickshire, carrying it out early helps identify tree related constraints in time to avoid redesign, reduce planning risk, and support a smoother application process.

FAQ - AIA in Manchester

Why are Arboricultural Impact Assessments important for developments in Manchester?

Arboricultural Impact Assessments are important in Manchester due to the city’s high density development and ongoing regeneration. Trees are often located within constrained urban sites, making it essential to assess how construction will affect their condition, stability, and long term retention.

Speak to Our Team

An AIA is typically required where trees are present on or adjacent to a development site and may be impacted by proposed works. In Manchester, this commonly applies to redevelopment projects, infill schemes, and sites where changes to access or ground conditions are proposed.

Check My Site

On brownfield sites, trees may be present alongside existing structures, hardstanding, or previous development. An AIA assesses how these trees interact with redevelopment proposals, helping to balance site clearance with opportunities for retention and urban greening.

Trees on inner city sites often face space constraints, soil compaction, and conflicts with underground services. In Manchester, an AIA identifies these challenges early, allowing for design solutions that reduce impact while retaining viable trees where possible.

Trees located within highways or neighbouring land can still be affected by development. An AIA will assess potential impacts on these trees, including changes to access, excavation works, and construction activity, ensuring they are properly considered within the planning process.

Can an Arboricultural Impact Assessment help improve urban design outcomes?

Yes. An AIA can inform better integration of trees into development layouts. In Manchester, this supports planning objectives around urban greening, improved public spaces, and enhancing the overall quality of the built environment.

Secure Survey

Trees are an important component of Manchester’s approach to sustainable development. Retaining and integrating trees can contribute to biodiversity, climate resilience, and improved living environments, all of which are considered within planning decisions.

Request Survey Quote

In Manchester, underground utilities are a common constraint. An AIA assesses how tree roots may interact with these services and recommends design or construction approaches that minimise damage to both trees and infrastructure.

In Manchester, Arboricultural Impact Assessments are typically required by Manchester City Council where trees are affected by development proposals. The council places strong emphasis on tree retention and urban greening within planning applications.

Carrying out an AIA early allows tree related constraints to be identified before designs are finalised. In Manchester, this helps reduce planning delays, minimise redesign, and ensure development proposals align with local policy and site constraints from the outset.

FAQ - AIA in Yorkshire

Why are Arboricultural Impact Assessments important for developments in Yorkshire?

Arboricultural Impact Assessments are important in Yorkshire due to the region’s wide ranging landscapes, from urban centres to extensive agricultural land. Trees often play a key role in defining site boundaries, shelter belts, and visual character, making their assessment essential within development proposals.

Speak to Our Team

An AIA is required where trees are present on or near a development site and may be affected by construction. In Yorkshire, this frequently applies to residential developments, farm diversification projects, and sites where tree belts or boundary planting are present.

Check My Site

On agricultural land, trees often exist as shelter belts, hedgerows, or field boundaries. An AIA ensures these features are properly assessed, helping to integrate development into the landscape while maintaining important structural and visual elements.

Large sites can include a wide range of tree types and conditions, from individual specimens to extensive woodland edges. In Yorkshire, an AIA provides a structured approach to assessing these features, ensuring that tree constraints are considered across the entire site.

Tree belts and boundary planting are assessed for their condition, extent, and contribution to the site. In Yorkshire, these features often provide screening, habitat connectivity, and wind protection, making them an important consideration within development design.

Can an Arboricultural Impact Assessment influence masterplanning?

Yes. On larger Yorkshire sites, an AIA can play a key role in shaping masterplans by identifying areas suitable for development and areas where tree retention should be prioritised. This helps create a balanced and practical site layout.

Secure Survey

Where removal is proposed, the AIA will assess the impact and provide justification. In Yorkshire, this may involve demonstrating that removal is necessary and proposing mitigation measures such as replacement planting or enhanced landscaping.

Request Survey Quote

Access routes and infrastructure can have widespread impacts on trees across large sites. An AIA evaluates these impacts and may recommend route adjustments or construction methods to reduce disturbance to retained trees.

Local Planning Authorities across Yorkshire commonly require Arboricultural Impact Assessments where trees are present. This includes Leeds City Council, Sheffield City Council, and York City Council. Each authority has its own validation requirements, which should be reviewed early.

Carrying out an AIA early helps identify tree related constraints before designs are finalised. In Yorkshire, this supports better site planning, reduces planning risk, and ensures development proposals align with both local policy and landscape considerations.

FAQ - AIA in Surrey

Why are Arboricultural Impact Assessments particularly important in Surrey?

Arboricultural Impact Assessments are particularly important in Surrey due to the county’s extensive tree cover, high value residential areas, and significant areas of Green Belt. Development proposals must demonstrate that trees are carefully considered and retained where possible to maintain landscape quality and planning compliance.

Speak to Our Team

An AIA is required where trees are present on or near a development site and could be affected by construction. In Surrey, this commonly applies to residential developments, extensions on large plots, and schemes within or adjacent to wooded or landscaped areas.

Check My Site

Within the Green Belt, protecting landscape character is a key planning priority. An AIA helps demonstrate that development proposals respect existing tree cover and integrate with the surrounding environment, which is critical when justifying proposals in sensitive locations.

Mature trees can influence building positions, foundation design, and access arrangements. In Surrey, where larger residential plots are common, an AIA helps identify these constraints and ensures development proposals work around important trees rather than compromising them.

Wooded sites require careful evaluation of tree groups, canopy cover, and root systems. An AIA assesses how development will affect these areas and identifies opportunities to retain key trees while accommodating practical site layouts.

Can an Arboricultural Impact Assessment help retain high value trees?

Yes. An AIA identifies trees of high quality or significance and provides recommendations to support their retention. In Surrey, this is particularly important where trees contribute to property value, visual amenity, or local character.

Secure Survey

Tree lined boundaries are common in Surrey and often form an important part of site screening and privacy. An AIA assesses how development may affect these features and recommends appropriate setbacks or protection measures to retain them.

Request Survey Quote

Where protected trees are affected, the AIA will clearly assess impacts and provide justification for any proposed works. In Surrey, formal consent is required from the Local Planning Authority, and strong emphasis is placed on retaining protected trees wherever possible.

Local Planning Authorities across Surrey frequently require Arboricultural Impact Assessments where trees are present. This includes Guildford Borough Council, Woking Borough Council, and Elmbridge Borough Council. Each authority has specific validation requirements that should be reviewed early.

Carrying out an AIA early helps identify tree related constraints before designs are finalised. In Surrey, this supports better site planning, reduces the risk of planning delays, and ensures development proposals align with local planning expectations and landscape sensitivities.
