Thames Ditton BS5837 survey

Tree survey information your project can actually use

Trees can influence more than the location of a new building. Driveways, parking, drainage, services, changes in level, demolition and working space can all affect the arboricultural position.

Send the current site plan and any Elmbridge wording. The survey should capture the trees that can influence the proposal, including relevant neighbouring trees, so the design team can work with a realistic constraint base.

A well-scoped Thames Ditton survey creates the base information needed to consider those relationships properly rather than discovering them one at a time later in the design.

What should you send before the survey is booked?

Start with the Thames Ditton site address, the latest architectural or site plan and the exact wording from Elmbridge, your architect or planning consultant. If a topographical survey exists, include it. If somebody has already prepared a tree report, send that too.

Those documents let us understand the stage of the project before we quote. A client who is still testing feasibility may only need the baseline survey and constraints information. A client with a completed planning layout may need the survey data to move directly into an AIA. A post-permission project may not need a fresh survey at all if the approved information remains suitable.

The aim is to commission the next useful piece of work, not the longest possible package.

From site visit to planning evidence

See how the survey feeds the design.

Survey work is only useful when the information carries cleanly into the drawings, assessment and protection strategy. These are the stages your project team may move through after the site visit.

01 · Site surveyMeasure the trees and understand the site.

02 · Design coordinationPut crowns, RPAs and tree quality in front of the designer.

03 · Planning & buildCarry the same evidence into AIA, AMS, TPP or supervision.

What happens on the survey

The site visit builds the evidence base for planning.

The exact extent depends on the site, but a planning survey normally records the tree information needed to understand quality, spatial constraints and the relationship with the proposed development.

Species & dimensions

Relevant trees and groups are identified and measured so the schedule has a reliable factual base.

Condition & category

Observations and BS5837 categories help the design team understand relative quality and retention value.

Crowns

Crown spread and clearance help test the proposed building, access and future relationship.

Root Protection Areas

Stem diameters provide the basis for RPAs that can then be mapped and considered against the design.

Before the site visit

A little preparation makes the survey more useful.

For a Thames Ditton site, it helps to have the current base plan ready before the visit. The surveyor can then relate tree references to the drawing the architect is actually using, flag obvious base-plan omissions and avoid creating a second naming system that the project team later has to reconcile.

Access is worth mentioning at quote stage too. Locked gates, dogs, tenants, adjoining land or trees that can only be viewed from one side may affect how the visit is arranged. None of that is unusual; it is simply easier to plan before the appointment than discover it after arrival.

When in doubt, send the information rather than trying to decide whether it matters. We can ignore an irrelevant drawing; we cannot take account of a planning condition, revised layout or access issue that we have never been shown.

Why people in Thames Ditton contact us

Four common points where a tree survey becomes necessary.

The page does not assume your project is one particular type. These examples are selected from the situations we regularly need to scope on development projects.

Planning validation

The council or planning agent has asked for a BS5837 tree survey before the application can progress.

Neighbouring trees

Trees outside the ownership boundary may still constrain the building, access or construction.

Drainage and services

Routes need to be coordinated before trenching or level changes are committed.

Early design

The architect wants tree positions, crowns and Root Protection Areas before fixing the layout.

Elmbridge planning context

The survey is the start of the evidence, not the end of it.

For Thames Ditton and Elmbridge, the key survey question is often how the building, access, surfacing and surrounding trees fit together.

Once the tree data is established, the next step depends on the design stage. A Tree Constraints Plan helps the architect before the proposal is settled. An Arboricultural Impact Assessment explains how the live layout affects trees. If permission is granted with tree conditions, an Arboricultural Method Statement, Tree Protection Plan and supervision can carry the approved strategy into construction.

Keeping those stages connected is useful for everybody: the client does not pay for repeated data collection, the architect has one consistent survey base, and the Local Planning Authority can follow the same tree references through the project.

01SurveyRecord the trees that can influence the site.
02ConstraintsPut crowns and RPAs onto the design base.
03ImpactAssess the actual planning layout.
04Protect & buildUse AMS, TPP and supervision where needed.

What can change the survey/report scope?

The site boundary is only one part of the picture.

These are the issues worth flagging when you first enquire because they can affect what information the project team will need next.

Neighbouring trees

Relevant trees beyond the ownership boundary may still influence foundations, crowns, access and design.

Driveways & hard surfacing

Parking and access can interact with RPAs even where the building itself is comfortably separated.

Drainage & services

Trenches and level changes need to be considered before routes are fixed close to retained trees.

Construction space

Scaffolding, plant, compounds, demolition and material storage can create impacts that are not obvious on the final layout.

Need more than the baseline survey?

These pages explain each later stage separately. You can also send the council wording and let the consultant identify the correct one for you.

Thames Ditton survey questions

BS5837 tree survey FAQs

General answers for planning projects in Thames Ditton. Send the exact authority wording where your application is already live.

Do I need a BS5837 tree survey for planning in Thames Ditton?

You may if trees on or close to the site can influence the proposed development or if Elmbridge has requested arboricultural information. Send the current plan and the exact wording and we can confirm the appropriate scope before you instruct.

Which planning authority covers Thames Ditton?

For this page the Local Planning Authority is Elmbridge Borough Council. Always use the wording from your own application, validation request or condition because that is the project-specific requirement that needs to be answered.

Does a TPO replace the need for a BS5837 survey?

No. TPO and conservation-area controls are separate legal matters. A development survey assesses the relationship between the project and the trees.

Can I get a fixed-fee proposal first?

Yes. The project information is reviewed before instruction so the proposal can define the work and fee clearly.

When would I need an AIA after the survey?

Usually once there is a sufficiently developed proposal to assess against the survey and constraints information.

What happens if the design changes after the survey?

The survey data may still be usable, but the impact of the revised footprint, access, drainage or surfacing should be checked before submission.

What does a BS5837 survey record?

The scope can include species, dimensions, life stage, condition observations, crown spread, stem diameter, category and the information needed to calculate Root Protection Areas.

Can you work directly with my architect?

Yes. Coordination is useful because tree references, survey data and the architectural drawing need to stay aligned as the design develops.
