Landscape bonds and maintenance conditions on new schemes

A landscape bond planning condition does not exist, and that single point explains most of the confusion on this subject. A condition cannot require the payment of money or the provision of a financial guarantee, so where an authority wants cash security that approved planting survives its establishment period, it has to take a planning obligation under section 106. What a condition can do is require the scheme to be implemented, require any losses to be replaced for a fixed period, and require a management plan to be approved and followed.

Two instruments, two legal bases, and a frequent muddle in draft heads of terms.

Why authorities seek landscape security

Landscaping is the part of a consented scheme most likely to go unbuilt or to fail quietly. It sits at the end of the programme, it is the first thing value-engineered, and nobody notices for two summers that half the trees are dead.

Officers know this, which is why landscape conditions are drafted tightly and why planting is one of the more commonly enforced breaches. The authority's interest is specific. Planting was part of the reason the scheme was acceptable, whether as screening, as townscape, as biodiversity mitigation or as the public landscape the committee was shown.

So the security is not punitive. It exists because the landscape drawing carried planning weight, and a dead landscape drawing means the permission delivered something different from what was approved.

Bonds against obligations in an agreement

The legal position is worth stating precisely. Planning Practice Guidance on the use of planning conditions is clear that conditions requiring a financial contribution or financial guarantee cannot be imposed, and the general tests require a condition to be necessary, relevant to planning, relevant to the development, enforceable, precise and reasonable in all other respects. A bond fails on the first point because it is a financial instrument, not a control on development.

A bond therefore sits in a section 106 agreement, which can oblige the owner to provide a bond, a cash deposit or a parent company guarantee in a defined sum, releasable on certification that the planting has established.

In practice authorities ask for a bond in three situations: large schemes with structural landscaping or public open space to be adopted, schemes where planting is the mitigation for a harm that would otherwise justify refusal, and applicants with no local track record. Most minor and many major permissions carry conditions alone.

Where a bond is sought, negotiate the sum, the trigger and the release. A sum calculated as the landscape contract value plus an allowance for establishment maintenance is defensible. A round figure per hectare is not, and asking how the figure was derived often reduces it.

Replacement planting periods and their wording

The standard replacement condition requires that any tree or shrub forming part of the approved scheme which dies, is removed or becomes seriously damaged or diseased within a stated period is replaced in the next planting season with another of the same species and size, unless the authority agrees otherwise in writing.

Five years is the conventional period for ordinary planting. Ten years appears for structural landscaping, for replacement trees secured under a tree preservation order and in some local design guides. Read the figure rather than assuming it.

Four drafting points are worth raising before the decision is issued:

• The trigger for implementation. First planting season following completion or first occupation of the development is workable. First planting season following the start of development is not, because the planting gets destroyed by the construction that follows.
• Whether the replacement obligation runs from implementation or from the date of the permission. From implementation is correct and is what the standard wording achieves.
• The species and size clause. Same species and size is sensible for a tree. For shrub mass planting it can produce absurd results, and a clause allowing a written variation handles it.
• Whether the condition covers the whole scheme or only trees. A condition referring to trees leaves hedges, grassland and wildflower areas unsecured.

A replacement condition is a continuing obligation. It is not discharged in the way an approval condition is, and it bites each time a plant fails inside the period.

Landscape management plans and who approves them

For anything with communal or public landscape, a separate condition requires a landscape management plan for approval. The plan is a different document from the planting scheme, and a Landscape Strategy submitted with the application is not a substitute for it.

What a management plan should contain is practical: management objectives for each landscape type, an operations schedule by year with frequencies, the responsible body, the funding mechanism, arrangements for monitoring and reporting, and a term. Terms of between five and thirty years appear, with the longer ones attached to habitat areas.

The approval route is the authority's landscape officer or tree officer rather than the case officer, which affects timing. Submit well before the trigger, because landscape officers are frequently part time or shared between authorities.

Keep this plan distinct from the biodiversity management obligations. The Environment Act 2021 regime requires habitat secured for biodiversity net gain to be managed and monitored for at least 30 years, and that obligation has its own legal basis, its own approval through the biodiversity gain plan and its own monitoring. Where the same area of grassland is doing both jobs, say so explicitly in both documents, and note that the statutory metric behind the Biodiversity Net Gain Assessment has to be completed by a competent person.

Adoption by the authority or a management company

Who ends up maintaining the landscape determines how the security is structured.

Where public open space is to be transferred to the council or to a parish, the agreement will usually require a commuted sum calculated on the authority's own published maintenance rates for a defined number of years, plus a defects or establishment period before transfer. Ask for the rates and the calculation, because they vary widely and are rarely challenged.

Where a management company retains the landscape, the agreement will require the company to be established, the land transferred to it, a management plan adopted and a service charge mechanism put in place before occupation of a defined number of units. The bond, if any, then covers the establishment period rather than the long term.

Where individual owners maintain their own planting, which is the position for front gardens and plot boundary hedges, the only realistic control is the replacement condition and the authority's willingness to enforce it.

Discharging the condition at the end of the period

Three separate events get confused here.

The approval condition is discharged when the authority approves the landscaping scheme, by a decision on an application for approval of details, with a fee per request under the national fees regulations, which are indexed annually.

The implementation obligation is satisfied when the planting goes in as approved, which the authority may verify by site inspection and which a developer should record with dated photographs and a contractor's certificate.

The bond is released when the agreement's release mechanism is triggered, typically a certificate from the authority or an agreed landscape architect that the planting has established at the end of the period. That certification is not automatic, and chasing it is somebody's job. Agreements that leave the release to the authority's discretion with no timescale are the ones that tie up capital for years, so push for a deemed release provision if the authority does not respond within a stated period.

The replacement condition simply expires at the end of its term. Nothing needs discharging.

Costs to allow for in the appraisal

Six line items, and the second and fifth are the ones usually missed.

The landscape contract itself. Establishment maintenance for the replacement period, which is watering, weeding, formative pruning and stake adjustment, and is a recurring cost rather than a contingency. The bond fee or the opportunity cost of the deposit, running for the whole period. Preparation of the management plan by a landscape professional. Any monitoring fee the authority charges under the agreement, which sits alongside the other monitoring fees attached to planning obligations. And the commuted sum where land is being adopted.

One honest observation to close on. Most landscape failures are not funding failures. They are specification and aftercare failures, where trees were planted into compacted construction ground with no irrigation plan, and no bond fixes that. Getting the soil specification and the aftercare schedule right at design stage is worth more than the security the council is asking for.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
