What this document is for

Tree Constraints Plan for Surrey projects

The Tree Constraints Plan is where survey data becomes a design tool. It places tree positions, crowns, categories and Root Protection Areas onto a plan so the architect can see the space the existing trees are asking the project to respect.

Using that information before the main footprint, driveway, parking or drainage is fixed can save a great deal of redesign. The TCP does not dictate the final layout, but it makes the trade-offs visible early enough for the design team to respond intelligently.

If you are still at feasibility or concept stage, send the topographical survey and whatever design information exists. The constraints plan can then become the common base for the architect, client and later AIA.

What you receive

The exact output is matched to the project, but the core deliverables normally include the items below. If the council has supplied its own wording, that request is reviewed first so the proposal is built around the live requirement.

Tree positions and references
Crown spreads
Root Protection Areas
BS5837 category information
Design-relevant annotations
Base plan for later impact assessment

Technical detail

What makes the work useful to planning and design teams.

The aim is not to produce a long report for its own sake. The information should answer the project question clearly and remain consistent with the drawings being used.

See the buildable space early

The TCP helps the designer understand where tree conflicts are unlikely and where a more deliberate design response may be necessary.

Tree value and spatial constraint together

Category information helps distinguish the relative significance of different constraints rather than treating every tree as identical.

Crown space matters too

A layout can sit outside an RPA and still create an uncomfortable future relationship with a large crown. Both above- and below-ground constraints matter.

One base for the whole process

Keeping tree references and survey data consistent from TCP through AIA and TPP makes the planning package easier to coordinate.

Before the document is issued

Quality control that keeps the information usable.

A Tree Constraints Plan is most valuable when it arrives while design choices are still open. Before issue, we check that the plotted crowns, RPAs and tree references can be understood alongside the site base. The purpose is to help the architect see opportunity and constraint at the same time.

It is not an impact assessment and it should not pretend the final design already exists. The TCP is an early design tool. Its job is to put the important tree relationships in front of the team before the footprint, access and hard landscape become unnecessarily difficult to change.

Finally, the document should make the next decision obvious. If another BS5837 stage is needed, it should be clear why and when. If the current document completes the immediate requirement, the client should not be pushed into commissioning extra work simply because it exists on a service list.

Where it fits in the BS5837 sequence

Survey first. Then use the next document only when the project is ready for it.

Most development projects near trees follow a recognisable sequence: establish the tree resource, map the constraints, assess the actual proposal, then set out the protection and construction methods needed to deliver it. Not every small project needs every document, and not every document should be commissioned at the same time.

If you are still designing, early survey and constraints information may be the most valuable spend. If you already have a stable layout, the impact assessment becomes more relevant. If planning permission is in place, the focus often moves to AMS, TPP and supervision. The quote should reflect the stage you are actually at.

Common project situations

When clients normally ask for Tree Constraints Plan.

If your situation is not listed, send the actual request. The site and planning stage are more important than matching a generic example.

Architect is testing early layouts

Infill site has mature boundary trees

Driveway options compete with tree constraints

Feasibility depends on understanding the real developable area

Information that speeds up the quote

Show us the project as it exists today.

Send the site address, current architectural drawing, topographical survey if available, and the exact wording from the council, tree officer, Building Control or project consultant. Include any earlier tree survey or report too. Existing information may still be useful and should be checked before repeat work is recommended.

If there is a submission date, condition-discharge deadline or construction start date, include that at the beginning. Programme can affect what needs to happen first.

Questions

Tree Constraints Plan FAQs

These are general planning answers. Your council condition or validation request may be more specific.

Is the TCP a planning submission document?

It can form part of the planning package, but its strongest value is often at design stage before the proposal is fixed.

Is it the same as a Tree Protection Plan?

No. A TCP shows design constraints; a TPP shows construction-stage protection measures.

Can my architect use it with the design drawings?

Yes. The purpose is to coordinate tree constraints with the evolving layout.

Does it show RPAs?

Yes, together with other survey information such as crowns and categories.

Should I get the TCP before an AIA?

Often yes, because it helps the design team respond to constraints before the finished proposal is assessed.
