Budgeting a travel plan and its monitoring contribution

A travel plan has four cost lines, and most appraisals carry only the first. There is the consultant fee for writing it. There are the travel surveys, at baseline and at each monitoring round. There is the coordinator, who is a real person with real hours for five years or more. And there is the authority's monitoring contribution, secured by planning obligation and payable whether or not your targets are met.

Budget all four at the same time as the transport evidence, because the monitoring obligation is negotiated in the section 106 agreement and by then the appraisal is usually fixed.

Framework and full travel plans

The distinction matters because it decides how much you are paying for now and how much later.

A framework travel plan sets the structure: the objectives, the mode share targets, the measures that will be available, the monitoring regime and the mechanism by which individual occupiers produce their own plans. It suits outline permissions, phased schemes and anything with multiple end users who are not yet known. It is shorter and less expensive to produce, and it defers the detail.

A full travel plan commits to specific measures for a known occupier or a known residential scheme, with named targets, a delivery programme, a coordinator and a monitoring schedule. It costs more to write and it is what the highway authority will want for a single-occupier scheme or a residential development with a defined mix.

Planning Practice Guidance on travel plans, transport assessments and statements sets out what each should contain and expects the scope to be proportionate to the scale of the development and the transport issues it raises. The practical reading of proportionate is that a 60-unit residential scheme needs a shorter document than a distribution warehouse with 400 staff on three shifts, and the authority's own guidance will usually say which it expects.

Where the scheme is large enough to need a Transport Assessment rather than a transport statement, assume a travel plan is coming with it. Councils usually expect a suitably qualified author for transport work, and professional review before submission is strongly advised.

Baseline surveys and when they can be done

On a new development there is no existing travel behaviour to survey, which creates a sequencing problem people only notice once the obligation is drafted.

The usual solution is to set the baseline after occupation, at a stated occupancy trigger, often expressed as a percentage of units occupied or a date after first occupation. The baseline survey then becomes the first monitoring round. Where a comparison is needed earlier, the plan draws on census travel-to-work data, the authority's own survey data or comparable sites, and says plainly that it is doing so.

Survey timing has rules that are worth insisting on in the drafting. Surveys should be carried out in neutral months, avoiding school holidays, late December and August, and should cover the days of the week that matter for the use. A survey window drafted as "within three months of occupation" can land in the school holidays and produce a baseline that makes your later targets harder to meet.

So negotiate the survey window as well as the survey frequency. A clause that requires surveys in a neutral month is a small amendment with a measurable benefit.

Targets, measures and the coordinator

Targets are usually expressed as a mode share shift: a reduction in single-occupancy car trips, or an increase in walking, cycling and public transport use, measured against the baseline over a stated period.

Set them from the measures you are actually delivering. A target that assumes a bus service improvement you are not funding is a target you will miss, and missing it triggers whatever remedial mechanism the agreement contains.

Measures that tend to be deliverable and defensible: a travel information pack for each occupier, cycle parking above the policy minimum with proper covered and secure provision, a car club bay with trial membership, discounted public transport passes for a defined period, personalised travel planning, a car park management regime, and good internal pedestrian and cycle routes. Measures that disappoint: notice boards, intranet pages and vague commitments to promote sustainable travel.

The coordinator is a cost line in its own right. The plan names a role, with contact details, responsibilities and a budget, and that person has to be in post from first occupation. On a residential scheme the role usually sits with the management company, which means the service charge carries it and the buyers need to be told. On a commercial scheme it sits with the occupier, which means it belongs in the lease.

Monitoring surveys after occupation

Monitoring rounds are typically set at intervals across a five year period following occupation, often in years one, three and five, with the plan reviewed after each round.

Each round costs money: the survey itself, the analysis, the report to the authority and the management time. Multiply the per-round cost by the number of rounds and put the total in the cash flow at the right years, because these fall after sales income on a residential scheme and after the appraisal has closed.

The iterative approach most authorities now use means a missed target does not automatically trigger a payment. It triggers a revision: the plan is updated with additional measures, agreed with the authority, and tested at the next round. That is a better outcome than a penalty, and it is worth drafting for.

One practical point on survey response rates. A residential travel survey with a poor response rate tells you very little and the authority can treat it as non-compliance with the obligation. Budget for incentivised response, and set the obligation against a reasonable response threshold rather than an absolute one.

The monitoring contribution secured by obligation

Local planning authorities can charge a monitoring fee for planning obligations, and the travel plan is one of the obligations most often monitored. The fee has to satisfy the statutory tests for obligations: necessary to make the development acceptable, directly related to the development, and fairly and reasonably related in scale and kind, under regulation 122 of the Community Infrastructure Levy Regulations 2010 as amended.

That last limb is the negotiating ground. A monitoring fee should reflect the officer time reasonably required to monitor the obligation, and an authority asking for a figure out of proportion to the work is vulnerable on the scale and kind test. Ask how the figure was calculated. Many authorities publish a monitoring fee schedule, and a published, reasoned figure is harder to argue with than an unexplained one, which cuts both ways.

Three drafting points worth money:

• Cap the total monitoring sum across all obligations rather than accepting a per-obligation charge with no ceiling.
• Agree indexation explicitly, and to a named index with a base date, rather than leaving it open.
• Tie payment to a trigger you control, such as implementation or first occupation, rather than to the date of the agreement.

The monitoring fee sits in the same part of the appraisal as the other obligations, and the interaction with viability is covered in budgeting a viability appraisal and the review it triggers.

Remedial mechanisms and what the tests allow

Some agreements go further than monitoring and require a remedial payment or a bond where targets are missed.

Approach these carefully. An obligation that operates as a penalty, rather than as a measure to make the development acceptable, is exposed on the regulation 122 tests. The more defensible structure is a remedial fund drawn down to pay for additional travel plan measures agreed with the authority, with any unspent balance returned. That is directly related to the development and it gives the authority what it actually wants, which is the behaviour change rather than the money.

Where a bond is proposed, check three things: what event triggers a call, who decides whether the trigger has occurred, and what the release mechanism is. A bond with no clear release date is a cost on the balance sheet for as long as it runs.

And read the definition of the target. A target expressed as an absolute mode share is harder to meet than one expressed as a shift from the measured baseline, and the difference between those two drafting choices can be the difference between a clean release and a remedial draw.

Negotiating the period and the cap

Five years of monitoring after full occupation is the common position for a residential scheme. Ten appears occasionally and is worth resisting on anything other than a large phased development, because the officer time it reflects is unlikely to be spent and the obligation has to be proportionate.

Four asks that authorities frequently accept:

1. A five year monitoring period from full occupation rather than from first occupation on a phased scheme.
2. A capped total monitoring sum with a stated index.
3. Survey windows restricted to neutral months, with a defined response threshold.
4. An iterative review mechanism in place of an automatic remedial payment.

Put the full cost of the Travel Plan in the appraisal as five separate lines: drafting, baseline survey, monitoring rounds, coordinator, and the authority's monitoring contribution. Most appraisals show one. The obligation is also the item least likely to appear in a consultant's quotation, and what is and is not included is covered in what a planning agent's fixed fee usually includes.

This is general guidance, not legal advice. Monitoring fees and obligation drafting vary by authority, so check the current position and take advice from a qualified professional before relying on it.
