Reports for a plot with a protected tree on the frontage

A Tree Preservation Order on the frontage does not stop you developing the plot, but it does add two things to the job: an arboricultural evidence base that the planning application cannot be validated without, and a separate consent regime for anything you want to do to the tree itself. Getting the tree preservation order plot reports right at the start is what keeps the driveway, the drainage and the foundations from being redesigned twice.

What the Order changes about your application

A Tree Preservation Order made under section 198 of the Town and Country Planning Act 1990, and administered through the Town and Country Planning (Tree Preservation) (England) Regulations 2012, makes it an offence to cut down, top, lop, uproot, wilfully damage or wilfully destroy a protected tree without consent.

Two consequences follow. First, the tree is a fixed constraint on the layout, and the council will expect the design to have responded to it rather than worked around it afterwards. Second, any pruning or felling needs a separate application for consent to works to a protected tree, which is decided in its own right.

Where the tree sits in a conservation area but is not covered by an Order, the regime is different. You give the council six weeks notice under section 211 of the 1990 Act, during which it can make an Order. Check which applies before you assume.

The 2012 Regulations do provide exemptions, including for dead trees, subject to giving the council five working days notice, and for urgent works to remove an immediate risk of serious harm. Those exemptions are narrow and the burden of proving them sits with you.

The arboricultural documents the council will ask for

Three documents do the work, and most validation lists name them.

A tree survey to BS 5837:2012 records every tree on and adjacent to the site, with its species, dimensions, condition, estimated remaining contribution and a retention category. Categories run from A, the highest value, through B and C to U for trees that should be removed regardless of development.

An Arboricultural Impact Assessment then tests the proposal against that survey and identifies losses, incursions into root protection areas and the effects of level changes. The Arboricultural Impact Assessment is where the argument about the protected tree is actually made.

A tree protection plan and an arboricultural method statement follow, showing the protective fencing, the construction exclusion zone and the method for any work inside it. Those are usually conditioned rather than required at validation, but preparing them early changes the design for the better.

Root protection areas and why the layout moves

BS 5837 sets out a method for calculating a root protection area from the stem diameter. For a single-stemmed tree it is a radius of twelve times the stem diameter, expressed as an area and subject to a cap, and the shape can be adjusted where soil conditions or existing structures justify it.

That circle is what collides with your scheme. On a frontage tree it typically takes in part of the driveway, part of the front garden and sometimes the corner of the proposed dwelling.

The usual answers are to move the building footprint back, to reduce the driveway width, or to use a no-dig construction over the root area with a cellular confinement system and a permeable surface above it. No-dig works, but it costs more than a normal driveway build-up and it needs designing rather than specifying in a sentence.

Level changes are the underrated risk. Raising ground level over roots by even a modest amount suffocates them, and lowering it severs them. Show existing and proposed levels across the root protection area on the drawings.

Shading is the argument that comes from the other direction. Where the tree overhangs the proposed dwelling, a neighbour or the applicant may later seek consent to reduce it because rooms are dark. Councils are alert to that, and a layout that creates the pressure for future pruning is a layout the tree officer will resist. Design the window positions and garden space so the tree can stay the size it is.

Services, drainage and the driveway

Trenching through a root protection area is where most tree damage on small sites happens, usually after permission has been granted.

Plan the service routes at design stage and put them outside the root protection area if there is any way to do it. Where a route has to cross, the options are a shared trench outside the area, thrust boring beneath the rooting zone, or hand digging under arboricultural supervision. All three need to be in the method statement.

Soakaways are a particular problem. A soakaway within the root protection area is usually unacceptable, and moving it can change the whole drainage design, so coordinate the tree constraint with the Drainage Strategy rather than resolving them separately.

Consent for works to the tree itself

If the scheme needs the tree pruned to give clearance, or a limb removed for access, that is a separate application to the council for consent under the Order. It has its own eight-week determination period in most cases and its own appeal route to the Planning Inspectorate.

Do not assume planning permission carries tree consent with it. It does not, unless the permission itself authorises the works and the Order's exemption for development authorised by planning permission applies, which is narrower than people expect.

Specify the pruning properly and in arboricultural terms. A request to reduce a crown by a stated percentage with no arboricultural justification invites refusal. A request framed around clearance over a highway or removal of deadwood, supported by the arboriculturist, usually does not.

Replacement planting and the conditions that follow

Where a protected tree is removed with consent, there is generally a duty to replace it, and the council can enforce that duty. Section 206 of the 1990 Act deals with replacement after removal in contravention, and consents routinely carry a replanting condition.

Councils also condition a landscape scheme, and on larger plots a Landscape Strategy covering species, sizes, positions and a five-year maintenance period is what gets the condition discharged. Match the replacement to the loss in canopy terms rather than tree for tree, because a semi-mature replacement does not replace a veteran.

Sequence the work as well. Protective fencing goes up before any machine arrives on site, not after the foundations are dug, and the arboriculturist's site monitoring visits should be named in the method statement with their timing.

The reports for a nine-unit scheme on a brownfield site show how the tree documents sit alongside the rest of the pack on a larger plot.
