Reapplying after a highway safety refusal

A refusal on highway safety grounds is different from a refusal on capacity grounds, and the difference decides whether reapplying is sensible. National policy says development should only be prevented or refused on highways grounds if there would be an unacceptable impact on highway safety, or if the residual cumulative impacts on the road network would be severe. The word severe attaches to the capacity limb. It does not soften the safety limb.

So an authority refusing on safety does not have to show that the effect is severe. It has to show that the impact is unacceptable, and the way to beat that is with measurement rather than argument.

Read what the highway authority actually objected to

Start with the consultation response, not the decision notice. The reason for refusal is usually a compressed version of a longer technical objection, and the detail is where the route back lies.

Sort the objection into categories.

• Visibility: the splay cannot be achieved, or it crosses land you do not control, or the y-distance assumed the wrong speed.
• Geometry: access width, radii, gradient, turning, gates, parking layout, manoeuvring within the site.
• Pedestrian provision: no footway link, a crossing point that does not work, an unsafe walking route to facilities.
• Capacity: trips added to a junction, which is the limb where severe applies.
• Inadequate information: the authority could not assess the proposal because something was missing.

The last category is the best news you can get. It is not a refusal on the merits, and a resubmission with the missing survey often clears it without any design change at all.

Our note on reading reasons for refusal sets out how to separate points that can be fixed from points that cannot.

Remeasure before you redesign

Most highway refusals on small sites rest on assumed numbers. Replace them with measured ones.

Commission a topographical survey covering the frontage and the full extent of the splay in both directions, with levels. Eye-height visibility from a design position is affected by a bank, a hedge on a bank and a rising verge, and none of those show on a location plan.

Commission a seven-day automatic traffic count at the access to establish the 85th percentile speed in each direction. This is the single most valuable piece of evidence on a rural or edge-of-settlement access, because the required y-distance follows the measured speed rather than the posted limit. Where the survey shows speeds materially below the limit, ask the highway authority to apply the appropriate standard for those speeds and put the request in writing.

Ask the highway authority for personal injury collision data for the section, usually for the last five years. A clean record does not prove safety, and inspectors say so. A record that shows nothing at your access and a cluster at a junction 300 metres away tells you where the officer's concern really comes from.

Then produce swept path drawings for the largest vehicle that will use the access, including a refuse vehicle if collection is from within the site, and check the parking and turning against the authority's adopted standards rather than against what looks reasonable on the drawing.

Changing the access position

Where visibility cannot be achieved at the proposed point, moving it is usually more productive than arguing about it.

Test three options on a plan before choosing. Relocating along the frontage, since moving away from the inside of a bend can transform the numbers. Sharing or upgrading an existing access, which sometimes carries established visibility and a known collision history. Taking access from a different road frontage entirely where the site has one.

Each option brings its own consequences. A relocated access may need more hedgerow removal, which brings the hedgerow procedures and the biodiversity metric into play. An upgraded shared access needs the agreement of everyone who uses it. Set these out in the covering documents so the officer can see the alternatives were considered rather than ignored.

Reducing the scale of the scheme is the other lever. Fewer units means fewer trips, and on a small site it can move a proposal below the threshold at which the highway authority asks for a full assessment. That is a commercial decision rather than a technical one.

Get the highway officer onside before you resubmit

The single most useful outcome before resubmission is a written statement from the highway authority that it no longer objects, or that it would not object subject to specified conditions.

The practical route is a pre-application enquiry with the highway authority, sending the survey results, the revised access drawing, the swept paths and a short note explaining what has changed. Many authorities charge for this and it is worth paying. Ask directly what would be needed to withdraw the objection, and ask for the answer in writing.

Take the answer literally. If the response says a 2.4 by 60 metre splay with nothing above 600 millimetres would be acceptable, draw exactly that, dimension it, and show the ground levels. Do not submit something close to it.

Where the fix depends on land you do not own, resolve that first. A splay across a neighbour's frontage needs either ownership, a legal right, or dedication as highway, and the correct ownership certificate served with notice to the other owner.

Using the fee-free resubmission

The fees regulations allow one further application without a fee where it is made by the same applicant on the same site, is of the same character or description as the earlier application, and is submitted within the prescribed period following the earlier decision. It is available after a refusal and after a withdrawal, and only once.

Two practical points. The concession applies to the planning fee, not to your consultant costs, and not to the survey work that makes the resubmission worth making. And it is time limited, so if the surveys will take three months, plan the sequence against the deadline rather than discovering it has passed.

Check the current fees regulations for the qualifying period and conditions before relying on it, since planning fees and their surrounding rules are indexed and amended.

The resubmission itself should be explicit about what has changed. A short covering statement listing each reason for refusal and what the revised scheme does about it saves the officer an afternoon, and officers remember that. Build the same structure into the Planning Statement, and put the technical evidence in a Transport Statement proportionate to the scale of the scheme.

When to appeal instead

Appeal rather than resubmit when three things are true at once: you believe the authority applied a standard mechanically without engaging with your evidence, your evidence is already complete, and the scheme cannot be improved further.

The mechanics matter. A householder appeal is decided on written representations and runs to a shorter timetable than a full appeal. For other applications the deadline is longer, and an appeal against a refusal must be lodged within the period stated on the decision notice. Check the date on your notice rather than working from a general rule.

Remember that an appeal tests the scheme that was refused. There is limited scope to amend a proposal at appeal, so an appeal is the wrong route where the answer is a different access design. It is the right route where the access is acceptable and the authority has simply not accepted the evidence.

Costs can be awarded where a party has behaved unreasonably, and refusing on highway safety grounds with no supporting evidence from the highway authority is one of the situations where applicants do apply. Appeal decisions on comparable accesses are useful as an indication of how inspectors have weighed measured speeds against adopted standards, and our note on using appeal decisions as evidence explains how to deploy them. They are indicative rather than binding.

This is general guidance, not legal advice. Highway standards, fees and appeal deadlines change, so check them with your local planning authority, the highway authority or a qualified professional before relying on them.
