Council-accepted arboricultural evidence for Surrey architects and developers. Secure your planning approval with our fixed-fee report suite.

Every tree is then assigned a BS5837 category (A, B, C, or U), which determines its retention value. This data is converted into a precise digital tree schedule, providing the council with the empirical foundation required to validate your application.
Before design finalisation, we map the Root Protection Areas (RPA) and crown spreads onto your topographical survey. This plan is crucial for avoiding costly design-based refusals; it visually dictates the "buildable" space, allowing architects to orient layouts around existing trees rather than over them, which is a major factor in securing early planning support.
The AIA is the primary evidence document scrutinized by the planning officer. It evaluates how your proposed development layout interacts with retained trees. We identify potential conflicts—such as hard surfacing in RPAs or required canopy pruning—and provide robust, policy-aligned mitigation strategies. This document is written as a direct "Planning Justification," explaining to the council why your scheme is compatible with arboricultural retention.
When development is permitted, councils often impose a "pre-commencement condition" requiring an AMS. This is a highly technical, operational document that specifies exactly how construction should be executed. It covers sensitive techniques like manual excavation, the installation of specialist cellular confinement systems (like Cellweb), and concrete pouring, proving to the council that retained trees will be protected throughout the entire build.
The final layer of compliance. We provide a scaled technical drawing that specifies the exact layout of protective fencing, signage, and construction exclusion zones. This plan acts as the visual guide for site managers and council tree officers during compliance inspections, ensuring that your site remains protected and that your development remains free from enforcement action or planning delays.
The Root Protection Area (RPA) is a mathematically calculated zone that must remain undisturbed to ensure tree survival. Traditionally, developers have been forced to abandon layouts that encroach on these zones. However, modern British Standards do allow for encroachment under highly specific, technically engineered conditions.
If your design necessitates a driveway or hard landscaping within an RPA, traditional excavation will be rejected. We engineer compliant solutions by specifying specialist "No-Dig" cellular confinement systems (such as Cellweb). Our Method Statements detail the exact installation tolerances of these 3D geo-synthetics, proving to the planning officer that structural roots will remain aerated, thereby securing your consent.
Surrey boasts an exceptionally high density of legally protected vegetation. A Tree Preservation Order (TPO) makes it a criminal offence to prune, fell, or wilfully damage a tree without explicit written consent from the council, carrying the risk of unlimited fines upon prosecution.
As part of our standard workflow, we conduct rigorous statutory checks with the local planning authority prior to visiting your site. If your proposal conflicts with a TPO or Conservation Area tree, our Impact Assessment is specifically engineered to demonstrate how your architectural design successfully mitigates harm, ensuring that statutory protection does not become an insurmountable blockade to your project.
Significant portions of Surrey are situated upon highly shrinkable clay subsoils. Clay is volumetric; it expands when saturated and shrinks dramatically when desiccated by the water demand of mature trees. This geological reality makes foundation design notoriously complex.
If your architect proposes foundations within the "zone of influence" of a tree, our BS5837 data is vital for your structural engineer. We provide the precise species identification and physiological profiles required to calculate foundation depths in strict accordance with NHBC Chapter 4.2 guidelines, preventing future tree-related subsidence and ensuring long-term structural stability.
