Safeguarded wharves on the Thames

A safeguarded wharf on the tidal Thames is protected for cargo handling by a direction made by the Secretary of State for Transport, and that protection applies whether or not the wharf is currently in use. Development on a safeguarded wharf will normally be refused unless you can show the site is no longer viable or capable of being made viable for cargo handling, which is a high bar and one that is assessed by the Mayor as well as by the borough.

What safeguarding protects

The purpose is capacity, not activity. River freight takes lorry movements off London's roads, and the wharves are the only points at which cargo can transfer between water and land. Once a wharf is built over with flats it is gone permanently, because the combination of deep water frontage, a river wall capable of taking berthing loads and a land area behind it cannot be recreated.

So the direction protects the physical asset and its operational potential. A wharf that has been empty for a decade is still safeguarded, and the fact of vacancy is not evidence that it cannot work.

That is the point most applicants get wrong. A disused wharf with a derelict shed looks like a redevelopment opportunity and is treated in policy terms as strategic infrastructure.

Check the designation before anything else. The list of safeguarded wharves is published, and the boundary on the ground is often wider than the operational yard, taking in land behind the frontage that the wharf would need to function. A site that appears to sit next to a wharf can turn out to be part of one.

How wharves are designated and reviewed

Designation runs through directions issued by the Secretary of State for Transport to the Mayor of London and the riparian boroughs, following a review of the wharves' capacity and potential. The reviews are periodic rather than continuous, and they consider whether each wharf remains needed to meet forecast cargo demand.

The London Plan's water transport policy sets the planning framework around the directions, within the wider Blue Ribbon Network approach to the river. Between reviews, the designation is a fixed constraint for anyone promoting a site.

Three things follow for an applicant.

• A proposal on or adjoining a safeguarded wharf will be referred to the Mayor and consulted on with the Port of London Authority as the navigation and harbour authority.
• The borough's local plan will carry its own policy protecting the wharf, usually with a site allocation that reflects the safeguarding.
• Release from safeguarding is a decision for the Secretary of State on the Mayor's advice, not something a borough can grant through a planning permission.

Development on or adjoining a wharf

For a scheme on the wharf itself, the starting position is that the use must be retained. Mixed schemes that keep a working wharf at ground and river level with residential above have been promoted, and they fail more often than they succeed, usually on the practical incompatibility of 24-hour cargo handling with homes directly above it.

For a scheme adjoining a wharf, the question changes. Here you are not removing capacity, you are risking it, because new neighbours bring complaints that constrain operating hours and eventually make the wharf unworkable. The London Plan's agent of change policy puts the burden on the incoming development to mitigate, and that is the policy you will be judged against.

Practically that means designing for the noise climate the wharf is entitled to generate at full operation, not the noise it makes today while half empty. Acoustic glazing with mechanical ventilation, non-habitable buffer uses on the wharf-facing elevation, balcony screening and a restriction on opening windows facing the operational area are the usual measures.

The evidence for release

If you are arguing a wharf is no longer capable of being made viable, expect the evidence base to be interrogated line by line.

What is normally required covers the physical condition and capacity of the river wall and berth, the dredged depth and tidal window, the land area available behind the wharf and its access to the road network, the ability to assemble a viable operating site, and marketing evidence showing the wharf was offered for cargo use on realistic terms over a sustained period.

Marketing evidence is where cases fail. An agent's board for six months at a rent set for a different use is not a test of demand. Sustained marketing, at a rent benchmarked to comparable cargo-handling sites, with the enquiries and the reasons they came to nothing recorded, is what carries weight. Our note on industrial land in London and no net loss covers the parallel evidence standard applied to industrial land, and the two tests behave similarly.

Viability in the development appraisal sense is not the question. A wharf can be worth more as flats and still be viable as a wharf, and the first fact is irrelevant to the safeguarding test.

Amenity conflicts with existing neighbours

Where homes already sit next to a working wharf, the operator's position is defensive. Complaints about early-morning loading, reversing alarms, dust from aggregates and lorry movements through residential streets are the recurring pattern.

The documents that resolve this are specific. A Noise Impact Assessment assessing plant and operational noise against the relevant standards, with the wharf's realistic operating profile rather than an averaged one. An Air Quality Assessment where aggregates, waste or bulk materials are handled, because dust is the complaint that generates most enforcement interest. And a Transport Assessment covering the land-side movements, since the river leg of the journey is only half the picture.

An operating management plan secured by condition is usually the mechanism. Delivery hours, the use of banksmen, wheel washing, sheeting of loads and a complaints procedure with a named contact are the terms that actually get used.

One caution on conditions. A condition restricting the wharf's own operating hours to protect new homes is the outcome safeguarding exists to prevent, so expect the Mayor to resist it even where the borough and the applicant are content.

Making the river freight case

For a scheme that reactivates a wharf, the argument is straightforward and worth making properly. Set out the tonnage the wharf could handle, the lorry movements displaced from the road network for that tonnage, and the catchment the wharf would serve.

Be careful with the numbers. Use the published cargo statistics and the harbour authority's own data rather than estimating, and state the assumptions behind any conversion between tonnage and vehicle movements. A reactivation case built on unsourced arithmetic invites the same scrutiny as a release case.

Where a wharf sits inside a wider regeneration area, the tension between safeguarding and the area's residential capacity will be live, and our note on what a London Opportunity Area allocation changes sets out how that balance is usually framed.

PlanScope drafts the planning, noise, air quality and transport documents around the evidence you supply, and marks any site data it does not hold rather than estimating it. For specialist technical reports, qualified professional input may be required. Reports should be reviewed before submission, and PlanScope does not guarantee planning approval.
