Creating a new vehicular access onto a rural lane

Forming a new opening onto a country lane is development, so new access planning permission is normally needed unless a specific permitted development right covers it. The application usually turns on one thing: whether a driver emerging from your gateway can see far enough along the road, and whether an approaching driver can see them. Everything else, the surfacing, the gates, the hedge, follows from that.

Rural accesses fail more often than urban ones because verges are soft, hedges are tall, and the recorded speed limit rarely matches the speed traffic actually travels.

When a new access needs permission

Section 55 of the Town and Country Planning Act 1990 treats the formation of a means of access as development, whether it involves engineering operations or a material change in the use of the land.

Two permitted development routes exist. Part 2 Class B of Schedule 2 to the GPDO 2015 permits the formation of an access to a highway that is not a trunk road or a classified road, where the access is required in connection with development permitted by another Class in the Schedule. So an access serving a permitted agricultural building can come with the building. It does not authorise an access to a classified road, and most rural lanes with a C or B number are classified.

Part 6 permits works reasonably necessary for agriculture on an agricultural unit, including private ways, subject to a prior approval application to the council covering siting and means of construction. Prior approval is not the same as planning permission and it does not remove the highway authority's separate consent.

Everything else is a planning application. That includes an access to serve a new dwelling, an access for equestrian or commercial use, and an access widened or relocated for reasons unconnected with agriculture. The related question of how an urban dropped kerb application runs alongside highways consent works the same way, though the technical standards differ.

Visibility splays and the speed survey behind them

A visibility splay is a triangle, described by two distances. The X distance is the set-back from the edge of the carriageway to the driver's eye, commonly 2.4 metres on lower speed roads. The Y distance runs along the nearer edge of the carriageway in both directions, and it is derived from stopping sight distance at the speed traffic actually travels.

That is why the speed survey matters. Highway officers work from measured 85th percentile wet weather speeds, not the posted limit. A 60mph national speed limit lane where traffic actually moves at 38mph produces a shorter required Y distance than the limit implies, and a 30mph village street where traffic runs at 36mph produces a longer one.

Two documents govern the geometry. Manual for Streets and Manual for Streets 2 cover lightly trafficked streets and lower speed roads. The Design Manual for Roads and Bridges applies to higher speed and strategic routes. Rural lanes sit awkwardly between them, and a highway officer will tell you which they want applied before you commission the survey.

Points that decide applications:

• the splay has to be within land you control or within the publicly maintainable highway, because a splay over a neighbour's field is unenforceable
• everything above about 0.6 metres inside the splay counts as an obstruction, including the hedge you were planning to keep
• the gate must be set back far enough for a vehicle to stand clear of the carriageway while it opens, commonly 5 metres or more for a car and more for a trailer
• the first few metres of the access should be bound surfacing so loose stone is not dragged onto the road
• surface water must not run from the access onto the highway

Agricultural access rights and their limits

Farms often have historic field gates that have been used for decades. Two traps follow.

First, the lawful use of a track or gateway is agricultural. Using it to serve a new dwelling, a holiday let or a livery yard is a material change of use of the access and needs permission, even though the physical opening already exists. Intensification of use is assessed on the same basis.

Second, prior approval under Part 6 is limited to siting and means of construction. It is not a highway safety consent, and the council will consult the highway authority anyway. Where the prior approval application shows an access onto a classified road, expect it to be refused or to attract a requirement for a full application.

Where the access serves a diversification project rather than agriculture, plan for a Transport Statement setting out trip generation, visibility, parking and turning. On a small rural scheme that document is short, and it is what the highway officer reads first.

Hedgerows, verges and the frontage

Most rural frontages are hedge. Removing a length of it to form a splay engages the Hedgerows Regulations 1997, which require a hedgerow removal notice to the local planning authority for hedgerows meeting the criteria in the Regulations, with a set of exemptions including removal to carry out development for which planning permission has been granted. Read the exemptions rather than assuming one applies.

Timing matters more than the paperwork. Cutting or removing hedgerow during the bird breeding season risks an offence under the Wildlife and Countryside Act 1981, and the practical window runs from around September to February. Where a hedge is species rich or forms a wildlife corridor, a Preliminary Ecological Appraisal should be commissioned before the design is fixed, and replacement planting set back behind the splay is the usual mitigation.

The verge itself is normally highway land maintainable at public expense, so you cannot excavate or surface it without the highway authority's consent, whatever your title plan shows.

Section 184, section 278 and who does the work

Planning permission does not authorise you to touch the highway. Two separate powers under the Highways Act 1980 do that.

Section 184 covers the construction of a vehicle crossing over a footway or verge, and the highway authority can require the work to be done by its own contractor or an approved contractor at your cost. Section 278 is an agreement for larger works in the highway, used where the access involves widening, a bellmouth with radii, drainage, a passing bay or changes to signing and lining.

Sequence the consents in this order:

1. Pre-application discussion with the highway authority on the splay standard and the road type.
2. Speed survey where the required Y distance is disputed.
3. Planning application including the access drawings.
4. Section 184 or section 278 consent, with technical approval of the construction detail.
5. Discharge of any planning conditions requiring the access to be built before first occupation.

Access to a trunk road is a different conversation again, involving National Highways rather than the county council, and new private accesses onto the strategic road network are resisted as a matter of national policy.

What to submit and how to answer a refusal

For an access-only application, the drawing set does most of the work: a location plan, a site plan with the red line covering the splay land, a detailed access plan at 1:200 or 1:500 showing X and Y distances with the splay hatched, a long section where the lane is on a gradient, and a swept path drawing for the largest vehicle you expect. Add photographs along the lane in both directions from the driver's eye height.

The Planning Statement should deal with the local plan highway safety policy, the speed data, and the fallback position if a lawful access already exists.

Illustrative example. A refusal reads: the proposed access would provide visibility of 43 metres to the north where 90 metres is required, and would give rise to conditions prejudicial to highway safety. The answer is rarely rhetorical. It is a measured speed survey showing a lower 85th percentile speed than assumed, a revised splay achieved by setting the hedge back on land within the applicant's control, or relocating the access 30 metres along the frontage to a straighter section. The figures are illustrative.

If none of those is possible, the access is in the wrong place, and moving it costs less than appealing.
