Discharging a tree replacement planting condition

To discharge a tree planting condition you have to give the council two things: a specification precise enough to be enforced, and evidence that what is in the ground matches it. Most refusals at discharge stage come from the first, and most problems two years later come from the second.

There are two routes to the same obligation and they behave differently. A landscape condition on a planning permission is discharged by an application for approval of details. A replanting duty following consent to fell a protected tree arises under section 206 of the Town and Country Planning Act 1990, applies automatically unless the authority dispenses with it, and the replacement tree becomes protected by the original order in its own right.

What the condition usually requires

Read the wording rather than assuming. Landscape conditions typically bundle several obligations that are discharged at different times.

• A planting plan and schedule to be approved before development, or before a stated stage.
• Implementation in the first planting season following occupation or completion.
• A maintenance and watering regime for a defined establishment period, normally five years.
• Replacement of any tree that dies, is removed or becomes seriously damaged within that period, in the next planting season, with a tree of the same size and species.

The replacement clause is a continuing obligation. It survives the discharge of the condition, and it binds successors in title, which is why a buyer's solicitor should be asking about it.

The specification detail officers look for

A schedule saying "6 native trees" will be refused. What a tree officer wants is enough detail to check the delivery against the approval.

Specify to the recognised standard for trees from nursery to independence, and to the nursery stock standard for the plant material itself. Naming the standards in the schedule saves an exchange of emails, because it tells the officer that quality, form and handling are covered.

Soil volume is the item most often missing and the one that decides whether the tree survives. A heavy standard tree in a 600 millimetre pit surrounded by compacted subgrade will be dead or stunted within five years, whatever the maintenance schedule says.

Planting season and the deadline trap

Bare root and rootballed stock goes in during the dormant season, roughly November to March, avoiding frozen or waterlogged ground. Containerised stock can be planted at other times with irrigation, at a higher cost and a higher failure rate.

The trap is a condition requiring planting within a fixed period that lands in June. Planting in midsummer to meet a deadline produces losses, and the losses then trigger the replacement clause.

The answer is to ask the council in writing to accept planting in the first available planting season, which most will do, and to keep the email. Where the condition wording cannot be met at all, a variation under section 73 is the formal route and it costs a fee and eight weeks.

Order stock early. Nurseries sell out of the larger girths, and substituting a smaller size without approval is a breach of the condition rather than a sensible field decision.

What to submit with the discharge application

1. The approved planting plan marked up as built, with any variations identified.
2. The planting schedule, with species, girth, root form and quantities.
3. Delivery notes or nursery invoices showing what was actually supplied.
4. Dated photographs of each tree in position, with a scale in frame.
5. The tree pit detail and soil specification used.
6. The maintenance schedule for the establishment period, including watering frequency and who carries it out.
7. Where an arboriculturist supervised, a short certificate confirming compliance.

Submit it as one document with the photographs captioned to the plan numbers. A discharge application that makes the officer cross-reference three files takes longer to determine than one that does the work for them.

A fee is payable for each discharge request, and the figures are revised periodically, so check the current schedule rather than relying on a number from a previous application. Where the planting forms part of a wider scheme, the approved Landscape Strategy is the document the details are measured against.

Establishment maintenance and the failure clause

Five years is the usual period and it is longer than most site teams remain on site. Decide at the outset who owns the obligation after handover: the developer, the management company or the plot owner.

Watering is the whole of establishment maintenance in practice. A newly planted standard tree needs a substantial volume through its first two summers, delivered slowly enough to reach the root ball rather than running off. Irrigation bags or a tube to the root zone work; a hosepipe for thirty seconds does not.

Weed and grass competition around the base is the second cause of failure, which is why the mulch ring is in the specification and why strimmer damage to the stem is worth designing out with a guard.

Keep the trees you already have as well. The protection measures that carry retained trees through the build are set out in retaining a tree through a construction programme, and a retained tree lost during the works usually triggers a replacement requirement of its own.

Monitoring visits and photographic records

Some councils inspect, most do not, and none of them remembers what the site looked like. Your photographic record is the evidence.

Photograph each tree at planting, at the end of the first growing season and at the end of the establishment period, from the same position each time, with the date recorded. Ten minutes twice a year produces a record that settles any later argument about whether the scheme was implemented.

Where the trees sit in or near the highway, the council's own procedures apply on top of the condition, and street trees, highway works and utility trenching covers what happens when a service run meets a planting position.

When planting fails after discharge

Discharge of the condition does not end the obligation. If a tree dies inside the establishment period, the replacement clause requires a like for like replacement in the next planting season, and the council can serve a breach of condition notice if it is not done. There is no appeal against such a notice, which makes it a poor thing to argue with.

Where the planting was a replacement for a tree felled under a tree preservation order, the enforcement route is different: the authority can serve a tree replacement notice requiring the tree to be replaced, within a time limit running from the failure to comply.

If a tree fails repeatedly in the same position, that is a site problem rather than a stock problem. Go back to the council with a proposal to relocate it or to change the species, supported by a short note on the reason, and get the change approved in writing. A Tree Survey to BS 5837 prepared at the outset usually shows why the position was difficult in the first place.
