Landscape and tree conditions: wording, timing and discharge

A landscaping condition on a planning permission usually does four things at once: it requires a scheme to be approved, sets when the planting has to go in, protects retained trees during construction, and obliges you to replace anything that dies within five years. Read the wording before you price the job, because the difference between "prior to commencement" and "prior to occupation" changes your programme by a season and sometimes by a year. Most disputes over landscaping conditions are about sequencing rather than about plants.

The standard set of tree and landscape conditions

Councils rarely write one landscape condition. A typical permission on a site with existing trees carries several, and they do different work.

• Approval of a soft landscaping scheme: species, sizes, densities, a planting plan and a schedule.
• Approval of hard landscaping: surfacing, levels, edgings, boundary treatments and lighting columns.
• Tree protection: an arboricultural method statement and tree protection plan to BS 5837:2012, with protective fencing erected before any machinery arrives.
• Arboricultural supervision: a named arboriculturist to be present for works inside a root protection area, with a schedule of site visits.
• Implementation and replacement: planting in the first available season and a five year replacement obligation.
• A landscape and ecological management plan where there is communal or public open space.

Each of those has to satisfy the six tests in national policy: necessary, relevant to planning, relevant to the development permitted, enforceable, precise, and reasonable in all other respects. A condition requiring "appropriate landscaping to be agreed" is imprecise and hard to enforce, and you can ask for it to be reworded before the decision is issued rather than arguing about it later.

Approval of details before or after commencement

Pre-commencement conditions are the ones that hurt. Section 100ZA of the Town and Country Planning Act 1990 means a local planning authority in England cannot impose a pre-commencement condition without the applicant's written agreement, following the procedure in the associated regulations. That gives you a window during the application to move a condition from pre-commencement to pre-occupation, or to accept it where it must bite first.

Tree protection is one that has to bite first. Fencing put up after the ground has been tracked over is worthless, and an officer will not accept a retrospective method statement. Soft landscaping details are different. There is no practical reason a planting plan has to be approved before the foundations are dug, and moving it to a pre-occupation trigger saves eight weeks off the critical path.

Watch for the condition that ties commencement to approval of the arboricultural method statement while another condition ties the method statement to a survey that has not been done. Read the conditions as a set and map them against the programme in the week the decision arrives, not in the week you want to start.

Planting seasons and why they drive timing

The standard implementation wording is some version of "in the first planting season following occupation or completion of the development, whichever is the sooner". A planting season for bare root and rootballed stock runs from about November to March, when the plants are dormant. Container grown stock is more flexible but still struggles if it goes in during a July dry spell without irrigation.

If you complete in April, you have effectively bought yourself seven months. If you complete in October, the planting has to happen almost immediately. That is worth knowing when the sales programme is set, because a site handed over with bare soil and no planting is both a condition breach and a poor first impression.

Where planting is impossible in the window, ask the council in writing for a temporary variation rather than missing the date silently. A Landscape Strategy submitted with the original application, showing phasing against a build programme, makes that conversation much shorter.

The five year replacement obligation

Almost every soft landscaping condition includes a replacement clause running for five years from planting, requiring anything that dies, is removed, or becomes seriously damaged or diseased to be replaced in the next planting season with stock of similar size and species.

Five years is longer than most defects periods. And that gap is where the commercial risk sits. The contractor's obligation may end at twelve or twenty-four months while the planning obligation runs on. On a scheme with any real quantity of planting, price a maintenance contract that matches the condition rather than the building contract, and hold a retention or a bond against it.

Failure rates on new planting are driven by watering in years one and two, not by species choice. Specify an establishment watering regime with volumes and frequency, name who does it, and keep the records. If the council serves a breach of condition notice four years in, the watering log is the evidence that the losses were not neglect.

Management plans for retained and new planting

On larger schemes the condition moves from a planting plan to a management plan, usually running five, ten or thirty years depending on what is being managed. Three separate regimes can end up on one site.

They overlap and they contradict each other more often than anyone admits. A landscape plan that specifies close mown amenity grass across an area the biodiversity metric counted as other neutral grassland will fail the habitat plan. Reconcile the drawings before either is submitted, because the Biodiversity Net Gain Assessment has to be completed by a competent person under the Environment Act 2021 regime and the habitat plan has to match what the metric assumed.

Discharging the conditions and closing the file

Discharge is an application for approval of details reserved by condition. It carries its own fee per request, and the authority has eight weeks to determine it unless a longer period is agreed. Submitting several conditions in one request is usually cheaper than submitting them one by one, though it also means one weak submission holds up the rest.

1. List every condition with its trigger and the evidence needed, in a schedule, on the day the decision notice arrives.
2. Commission the surveys and drawings that feed the pre-commencement conditions first, allowing time for the arboriculturist to visit in leaf where canopy assessment matters.
3. Submit the pre-commencement package as a group, with a covering note that cross refers each document to each condition number.
4. Erect and photograph the tree protection fencing before the first delivery, with dates.
5. Keep a discharge log, and chase at week six rather than week nine.
6. Apply for confirmation of compliance at the end, so the file is clean for a purchaser's solicitor.

There is a deemed discharge route in England for certain conditions where the authority has not determined in time, but several categories are excluded and the notice procedure is precise. Check whether your condition qualifies before relying on it.

A Tree Survey prepared to BS 5837:2012 at the design stage, rather than after a refusal, is what keeps most of these conditions manageable, because the retained trees and their root protection areas are then already reflected in the layout. Councils condition what the drawings did not resolve.

This is general guidance, not legal advice, and condition wording varies between authorities, so check the position with your local planning authority or a qualified professional before relying on it.
