Have your say on the proposals for Sizewell C

Building Sizewell C would help the country move away from polluting fossil fuels like coal and gas and play a major role in fighting climate change. Alongside our Sizewell B and Hinkley Point C power stations, it will help an almost totally carbon-free electricity system work more reliably and affordably. Our nuclear power stations will help the electricity system cope better when there is little wind and solar power produced.

With the benefit of feedback from three stages of consultation and continued environmental and technical studies, we have continued to update and improve our proposals. Before finalising our application for development consent, we are seeking your views at this Stage 4 consultation on a number of potential changes we think may improve the proposals further including a new integrated freight management strategy.

Stage 4 runs from 18 July to 27 September 2019. The purpose of this consultation is to provide an update on some proposals that have changed since Stage 3 and to introduce an alternative, third option for moving materials on and off site during the construction period. These proposals emerged in light of feedback at Stage 3 and on-going engagement with stakeholders.

Our proposals

The power station

Operational masterplan for the main development site

We plan to build and operate a new nuclear power station in Suffolk on land immediately to the north of Sizewell B power station, adjacent to an area that has had nuclear power stations operating since 1966.

Should we receive the necessary consents, we expect construction of the power station to take between 9 and 12 years.

Components of the power station

The proposed design of the Sizewell C buildings takes into account the sensitive nature of the surrounding environment while providing enough space to build and operate the power station safely and efficiently. There are some minor proposed changes to the boundary of the main development site since at Stage 4 to allow for updated proposals or as a result of discussions with landowners.

The permanent components of Sizewell C would be:

  • two UK EPR™ reactor units made up of reactor and associated buildings, plant and infrastructure, and turbine halls and electrical buildings;
  • fuel and waste facilities, including interim storage for radioactive waste and spent fuel;

  • an operational service centre (including offices), a training building, and ancillary, office and storage buildings;

  • a cooling water system and combined drainage outfall in the North Sea;

  • drainage and sewerage infrastructure;

  • transmission infrastructure including 400kV overhead lines and pylons, a National Grid 400kV substation and associated modifications to the existing National Grid transmission lines;

  • backup power source and emergency response equipment store at Upper Abbey Farm;

  • internal roads, a causeway to cross the Sizewell Marshes Site of Special Scientific Interest (SSSI), car parking, and a vehicle search area;

  • sea defence and a beach landing facility;

  • a helipad for infrequent use by Sizewell B and Sizewell C, replacing the existing emergency landing site at Sizewell B on the outage car park;

  • an access road including a new roundabout to join the B1122; and

  • landscaping of the areas to be restored following use during construction.

Electricity pylons

At Stage 3 we proposed four pylons to export electricity generated by Sizewell C via overhead lines to the National Grid substation. In recent months, National Grid has been examining our proposals and refining the design. This has resulted in a proposed extension of the development boundary to include the full area underneath the overhead lines to allow the works to be carried out.

We are now considering two options – either a four pylon or five pylon option - for minimising the visual impact of the pylons needed to export electricity generated by Sizewell C. For details, please see the Stage 4 Consultation Summary Document.

Environmental considerations – main development site

Construction of the power station would have an impact on the surrounding environment. Since Stage 3 consultation we have continued to undertake environmental surveys and identify likely impacts to help inform our proposals. Where impacts are likely to be significant, we have embedded mitigation into our design, or are proposing separate measures to reduce them. 


Additional land for mitigation

We have created a new wildlife habitat at Aldhurst Farm, Leiston, to benefit people and wildlife, and to help compensate for any future potential land-take from the Sizewell Marshes Site of Special Scientific Interest (SSSI).

In response to feedback from Stage 3 consultation and further technical and environmental work, we are also now proposing to include additional land for mitigation within the development boundary, including:

  • at Kenton Hills car park, to provide improvements to the car park and the access into the Kenton Hills woodland;

  • three additional potential sites to support the marsh harrier breeding population in case our current work to establish habitats on the EDF Energy estate does not provide sufficient foraging area;

  • two potential sites to compensate for the loss of fen meadow habitats from the SSSI; and

  • around 90,000 cubic metres of replacement floodplain in two locations to mitigate for losses due to the construction and operation of the SSSI crossing.


Sizewell C site access

We are proposing to build a new, permanent, two-lane access road with a segregated route for cyclists and pedestrians to link Sizewell C to the B1122 with a roundabout. This would be the main route to bring workers and materials onto the site during construction and the main access for Sizewell C once the power station is operational. We are now proposing to extend the development boundary to allow for a larger roundabout if needed to accommodate the Suffolk County Council preference for the speed limit through the roundabout be 40mph rather than the 30mph proposed at Stage 3. We are assessing the environmental impacts of this change, including on woodland, Greenhouse Plantation, and Leiston Abbey, and will take steps to minimise the impact.

The new access road would need to cross the Sizewell Marshes SSSI to reach the power station platform. With a more detailed understanding of the construction process and likely environmental impacts, our proposal for the crossing is a causeway over a culvert.

This access road is a regulatory requirement, as all new nuclear power stations need to have two separate entrances. The existing Sizewell power station road would provide the secondary access and would be rarely used after approximately the first year of construction. As we develop our proposals further we will continue to seek ways to limit disruption to local residents and road users during this initial period.

Beach landing facility (operational phase)

While we no longer propose moving freight by sea due to the impact on marine ecology of building a jetty, the need for a permanent beach landing facility (BLF) during the operational phase of Sizewell C remains. The BLF would facilitate an occasional - but essential - need to transport across the shore exceptionally large loads that are too big for transportation by road. We are also proposing to use the BLF during construction.


Construction and temporary development

Our proposals for construction and temporary development aim to avoid significant adverse environmental effects. Where this is not possible, we will embed mitigation measures in our design in a way which is environmentally responsible and sensitive to the needs of the local community.

The main development site includes:

  • construction working compounds (parking, laydown areas, working areas, and related works and structures);

  • an induction centre, site offices, and temporary structures, including a concrete batching plant;

  • temporary rail infrastructure (for the rail-led strategy only);

  • site access, construction roads, fencing, lighting, security features, landscape bunds and screening;

  • temporary spoil management areas, including borrow pits and stockpiles;

  • public access works including permanent and temporary closures and diversions of public rights of way;

  • water management zones, utilities and services infrastructure; and

  • an accommodation campus.


Existing woodland and areas identified for early tree/ hedgerow planting would help screen activities, including at the site entrance and along the northern perimeter. Differences in the height of land to the north and south of the site would also help screen construction activity from wider views. Temporary noise screening, including bunds and fencing would be used in a number of locations to reduce impacts of construction noise on adjacent areas.

A site entrance hub east of the new B1122 junction would serve as an access point for goods vehicles transporting construction materials as well as for workers and visitors to the site, ensuring safe and secure access to the site. This would operate outside the main security fence to allow more flexibility in operation and would include a site office, induction centre, canteen and access to the accommodation campus. A freight area with a checkpoint, security checking facilities and parking is also proposed.

A secondary access from Lover’s Lane would be required to connect the main development site to land east of Eastlands Industrial Estate (LEEIE), the area directly north of Sizewell Halt. This would also serve as an emergency access point in the event of an obstruction at the main development site entrance.

The workers’ accommodation campus would help mitigate potential impacts on local communities by reducing pressure on local accommodation. It offers significant benefits in reducing journeys on local roads and wider worker management.

Sizewell B nuclear power station

Relocation of Sizewell B facilities

For some time, the owner of Sizewell B (a subsidiary of EDF Energy) has planned to upgrade and relocate some facilities in closer proximity to the main Sizewell B operation, allowing Sizewell C to use the land where they are currently positioned. These works are critical for the construction of Sizewell C. NGL submitted a separate planning application to East Suffolk Council in April 2019 and this is currently being considered by the Council.

Public rights of way and Bridleway 19 diversion

Bridleway 19 would be diverted throughout the construction phase onto a single 3m-wide route surfaced to bridleway standards and with waiting boxes at crossing points. While the route has not changed since Stage 3, we are now proposing to include more land to allow for improvements including a footpath linking the caravan site to the main construction site, a design change reducing the number of crossings users would need to make, and a wider development corridor.


Managing construction materials

The deep excavation needed to build Sizewell C would generate large amounts of spoil and a need for material to replace or backfill it. Feedback from consultation along with our technical work has confirmed our preference for keeping construction material on-site.

We are proposing to source construction material for use in building the power station from ‘borrow pits’ which would be backfilled with peat and clay excavated from the foundation area of the power station. We are also proposing a number of stockpile areas for storage of construction materials.

People and economy

The impacts of Sizewell C overall would be overwhelmingly positive, bringing significant economic and employment opportunities, supporting the security of the UK’s economic future and producing a long-term boost for the local economy.


Local economic benefits

Our expectation remains that the power station would put at least £100 million a year into the regional economy during peak construction and £40 million per year during its 60 years of operation. This is based on the Hinkley Point C application for development consent.

While the potential benefits are substantial, we recognize that Sizewell C could also result in adverse social or economic effects, and our overarching approach is to avoid, mitigate, or manage these. Our work in these areas will be supported by separate Health Impact Assessment and Community Impact Reports, which will form part of our application for development consent.

Construction worker

Construction workforce

Construction of Sizewell C would create approximately 25,000 roles on the main development site during the construction phase. We are aiming to meet the nuclear sector target of a 40% female workforce and a minimum target of 1,000 apprentices. There will also be a need for a significant workforce in non-construction roles, both directly and in the supply chain. Once operational, there would be a long-term legacy of 900 new jobs.

Supply chain

Wherever possible, we are aiming to ensure local businesses can compete for the significant number of contracts needed to build, support and operate Sizewell C. For more information or to register an interest, along with more than 1,300 companies already on the database, please visit: sizewellcsupplychain.co.uk.

We are already working with Suffolk Chamber of Commerce to build and operate a supply chain database enabling local businesses to register and get ‘Fit for Nuclear’ - the industry benchmark for nuclear-ready manufacturers. We anticipate that the Chamber’s role will expand for construction, to start matching suppliers with Sizewell C requirements, communicate contract opportunities, and connect suppliers with support to meet quality and safety standards.

A Supply Chain Engagement Strategy, setting out the steps we have taken to understand and support the local supply chain and identifying potential local benefits, will form part of our application for development consent.

Education, skills and employment

We are committed to ensuring local people are able to access the jobs and benefits Sizewell C would bring. We will support an education, skills and employment programme specifically to ensure that a maximum number of local people benefit from opportunities on the project. In all areas of work at Sizewell C there will be jobs and progression routes for local people to develop into supervisor and management roles.

A wide range of jobs will be available through the different phases of Sizewell C construction. Roles during the main phases of construction include:


With over 1,700 life-of-project roles available, including more than 700 high level security officers and drivers, and over 600 operations support, administrator, and document controller roles, there are excellent opportunities for returners to work and adult ‘re-skillers’. Investment in their training will take place following development consent and subsequent investment decision. 


Includes a need for more than 1,900 people, including 650 construction general operatives. These roles will build on construction skills already prevalent in the local area and act as a route into the civil construction phase. Many of the qualifications required are already catered for by further education colleges in the region and will provide an excellent ‘spring board’ for local people who want to develop a sustainable career in construction or civil engineering. There will also be a requirement for plant roles including more than 300 excavator operators. Training for Heavy Plant is not commonly found in Suffolk. If the region is to plan and provide for such skills, investment is likely to be needed in this area. 

Civil construction

Requires over 2,300 roles, including more than 800 steel fixers, 450 lifting operations technicians, over 450 qualified supervisors, and more than 225 site technicians and graduate engineers. All of these roles require training implementation at or before the start of construction in order to offer significant and sustainable opportunities for local people. 

Mechanical, electrical, and air conditioning

Has a need for more than 3,300 roles, including 490 welders, 800 electricians, 600 engineers, and 300 cable installation workers. While this phase presents a significant challenge as there is a UK-wide skills shortage in this area, there is also an excellent opportunity to transfer and develop the training offer from Hinkley Point C to the East of England and broaden the pool of the local and regional workforce in these high demand areas. Training investments are likely to be required up to three years ahead of need if the region is to capitalise on these opportunities.

Jobs available during construction



We recognise that tourism is an important source of jobs and income in many areas of the local economy, in particular within the Suffolk Coast and Heaths Area of Outstanding National Beauty (AONB). We are working with key organisations, including local authorities, Suffolk Coast Destination Management Organisation, Visit Suffolk and the New Anglia Local Enterprise Partnership to understand the local tourist economy and Sizewell C’s potential effects on it. We have also started identifying opportunities and mitigation measures - including a potential Tourism Fund - that could support the area’s tourist economy.


Public services and community facilities

We recognise local concerns about the impact of construction, including the size, location and activities of the workforce. To ensure high standards of behaviour from our workforce, both on-site and in the community, all Sizewell C workers would be required to sign and comply with a strict Code of Conduct, including mandatory drug and alcohol testing. Failure to comply with the Code of Conduct may result in dismissal.

We continue to work with the local authorities and emergency services to understand potential effects on healthcare, social care for adults and young people, the use of local services in settlements close to the site, and the potential effects on emergency response in the community. We have also established an emergency services working group - including fire and rescue, police and ambulance services - to determine the level of additional need - and potential mitigation required - that may arise as a result of Sizewell C.


The overall aim of our accommodation strategy is to strike a balance between providing temporary worker accommodation and workers using existing local accommodation, in order to minimise impacts on the community while promoting the economic benefits of workers living and spending in the area.

To ensure our assessments are robust in relation to transport, environmental effects, worker accommodation and impact on services, we are assessing what the effect would be of having up to 8,500 workers (7,900 on the main development site and 600 on the associated development sites) at the peak of construction.

A larger workforce would not affect the scale of the physical components of Sizewell C, although it may require additional mitigation.

Sketch of the proposed campus layout

Main development site campus

A single, on-site accommodation campus for 2,400 workers is a key part of our proposals. Our proposal is to locate all development to the east side of Eastbridge Road and to build the associated sports facilities remotely at a site in Leiston.

We have revised the layout of the campus to address concerns of massing and height of the buildings. We are now proposing only three-storey and four-storey (rather than up to five-storey) accommodation buildings. The three-storey buildings would be nearest to Eastbridge Road and the four-storey buildings further east. 

The campus would play an important role in helping to:

  • reduce the number of journeys made by workers on local roads;
  • reduce pressure on tourist accommodation and the private rental market;
  • allow flexible working patterns and out of hours working that would be necessary to maintain construction productivity and progress;
  • allow us to manage worker behaviour and impacts on the wider community; and
  • bring benefits for local businesses supplying goods and services to the campus.
Sports pitches available at Hinkley Point C

Sports facilities

We are proposing to provide off-site sports facilities, including a full-sized synthetic sports pitch and two multi-use games areas, on land between Leiston Leisure Centre and Alde Valley Academy. Consultation with local authorities and stakeholders showed a preference for locating the sports facilities in the north-west corner of the field closer to the existing leisure centre and car park. At Stage 4, we have changed the development boundary to include the entire field, allowing flexibility as the design continues to develop. 

Caravan accommodation

Our proposed caravan site on land to the east of Eastlands Industrial Estate (LEEIE) would be available in the early years before the campus is established and retained throughout construction as an option for workers. The current proposal would allow around 400 pitches.Caravan accommodation

Our proposed caravan site on land to the east of Eastlands Industrial Estate (LEEIE) would be available in the early years before the campus is established and retained throughout construction as an option for workers. The current proposal would allow around 400 pitches.


Building Sizewell C would involve the daily movement of large numbers of construction workers and significant amounts of materials and equipment. In developing and designing our transport proposals, we have sought opportunities to limit the impact of construction of Sizewell C on the local highway network wherever possible. Our proposals include mitigation measures to limit potential effects on local communities and the environment.

The key elements of our strategy are to:

  • use either a rail-led or road-led approach to moving materials onto and off-site;

  • build an on-site accommodation campus to reduce the number of workforce journeys;

  • provide park and ride facilities at key locations on the A12 for workers to travel by bus to the main site;

  • provide direct bus services from Ipswich and Lowestoft;

  • provide direct bus services to and from Saxmundham station;

  • operate working patterns that minimise workers travelling at peak times;

  • provide local bus services from Leiston; and

  • provide road improvements where necessary to mitigate the impact of construction traffic.


Movement of materials

In developing our freight management strategies, we have aimed to:

  • maximise use of rail infrastructure while avoiding disruption of existing passenger services;
  • limit the impact of Sizewell C construction on the local highway network wherever possible; and
  • mitigate environmental impacts.


We are now considering three options for the movement of freight - the rail-led and road-led strategies presented at Stage 3, and a new integrated strategy being presented in our Stage 4 consultation.

The rail-led strategy would provide direct access into the main site for five trains a day using a new rail line (known as the green rail route), and a road bypass of Theberton.

The road-led strategy would provide a new Sizewell link road from the A12 to the B1122, and a freight management facility to the east of Ipswich, along with two trains a day (to Sizewell Halt or a new rail siding) throughout construction.

The integrated strategy, combining elements of both the rail-led and road-led strategies would provide direct access into the main site for three trains a day along the green rail route, a new Sizewell link road, and a freight management strategy near Ipswich.

Features common to all three strategies, include:

  • a bypass (either the Theberton bypass or Sizewell link road) to mitigate the reduce the impact of construction traffic on the B1122 through Theberton;

  • a beach landing facility;

  • options for use of Sizewell Halt or construction of a new rail siding or spur and use of existing rail lines;

  • HGV management activities; and

  • road improvements, including a bypass of Farnham and Stratford St Andrew (A12 two village bypass) and other highway improvements.


We are considering two options for the location of the freight management facility proposed under the road-led and integrated strategies. We are proposing some changes to both sites at Stage 4.

For details and to learn about options within our proposals for the movement of materials, please read the Stage 4 Consultation Summary Document

Theberton bypass or Sizewell link road

We are proposing a bypass to reduce the impact of peak construction traffic on the B1122 through Theberton. Under the rail-led strategy, the Theberton bypass would run from a point between Middleton Moor and Theberton, and end on the B1122 east of Theberton. Under the road-led and integrated strategies, the bypass would be known as the Sizewell link road. It would incorporate the route of the Theberton bypass and extend further to also bypass Middleton Moor, joining the A12 south of Yoxford.

At Stage 3 we proposed that the additional B1122 mitigation (either the Theberton bypass or Sizewell link road) would remain in place after construction is completed. At Stage 4, we are seeking your views on whether all or part of it should be a temporary feature pen-square, removed and the land restored once Sizewell C is operational. We are also consulting on some minor changes to the proposed development boundaries of Theberton bypass and Sizewell link road. 

Beach landing facility

A permanent beach landing facility (BLF) is needed for handling abnormally large deliveries during the operational phase of the power station. Although not suitable for movements of bulk aggregates, the BLF would also be used throughout the construction phase to remove the need for heavy and oversized loads to be taken on the road network. It would be designed for use by barges, loaded with deliveries elsewhere, towed to the Suffolk Coast, and moored in position before the barge is beached. The abnormally large deliveries would be transported to site along an access road incorporated into the northern mound.

Sizewell Halt or new railing siding or spur

We are proposing to use the existing rail terminal known as Sizewell Halt or a new rail siding or spur for freight deliveries in the early years of construction. Under the road-led strategy, the proposal for two trains a day will continue throughout the construction phase. The proposal for a spur is new at Stage 4 and details of all three options can be found in the Stage 4 Consultation Summary Document.

Rail proposals

All three strategies would require track upgrades to the Saxmundham to Leiston branch line. Nine level crossings between the Saxmundham junction and Sizewell Halt would also need to be upgraded. There is no change to the nature of the works proposed at Stage 3, however we are now proposing to include the entirety of the branch line within our development boundary to enable either EDF Energy or Network Rail to do the upgrades. The rail-led strategy would include significant improvements to the East Suffolk line, including upgrades of up to 33 and closure or diversion of 12 level crossings.

HGV management

All three strategies would also be supported by a number of other activities to manage heavy goods vehicles (HGV) deliveries and movements to and from the main development site, including:

  • an electronic web-based Delivery Management System (DMS) to allocate HGV delivery slots and ensure compliance with agreed controls and limits. It would also allow rapid electronic communication with suppliers should deliveries need to be delayed or rescheduled due to issues on the highway network.

  • use of mandatory routes for Sizewell C HGV construction traffic, enforced with the use of Automatic Number Plate Recognition (ANPR) cameras; and

  • temporary holding or controlled release of HGVs from the Sizewell C site.


Road improvements

While our proposals have been designed to limit potential impacts on the local road network, we recognise that the A12 and B1122 are particularly likely to be affected by construction traffic. To limit adverse effects and address potential capacity and safety issues, we are proposing a number of mitigation measures separate to those proposed under the rail-led or road-led strategies.

A12 two village bypass: we recognise that Sizewell C traffic would exacerbate an existing problem on the A12 at the Farnham bend. We are proposing a bypass of Farnham and Stratford St Andrew (a two village bypass) to significantly reduce the traffic passing through the narrow bend at Farnham. The route of the single carriageway road remains unchanged since Stage 3 consultation, however in this Stage 4 consultation we are proposing some minor changes in response to feedback and our further environmental studies which would require amendments to the proposed development boundary. For further details see the Stage 4 Consultation Summary Document.

Yoxford roundabout: the B1122 would experience a significant increase in traffic as a result of Sizewell C. Our proposal to improve the junction of the B1122 with the A12 at Yoxford is a roundabout. It would replace the existing priority junction and is considered to be safer and more efficient than signalising the existing A12/B1122 junction. At Stage 4 we are proposing to locate the roundabout approximately 20m to the south east compared with Stage 3, with a revised development boundary to the south of the site. These changes will enable us to reduce traffic delays due to construction vehicles and avoid encroaching into the adjoining nature reserve.

Junction improvements: we are proposing road improvements - such as changes to signage and road markings, vegetation maintenance, speed limit changes, and other developments - at a number of key junctions to improve safety. At Stage 4 we are proposing minor development boundary changes to a number of the junctions. Further details can be found in the Stage 4 Consultation Summary Document.

A140/B1078 west of Coddenham: changes to signage and road markings as well as vegetation maintenance to improve visibility and safety at the junction;

B1078/B1079 east of Easton and Otley College: changes to signage and road markings as well as vegetation maintenance to improve visibility and safety at the junction;

A12/B1119 at Saxmundham: changes to signage and road markings, and vegetation maintenance to improvevisibility and safety at the junction;

A1094/B1069 south of Knodishall: changes to signage and road markings, and vegetation maintenance to improve visibility and safety at the junction. We would also ask Suffolk County Council to promote a reduction in the speed limit at the junction to 40mph to assist vehicles turning right out of the B1069 to find suitable gaps in the A1094 traffic and safely complete the manoeuvre;

A12/A1094 Friday Street, north of Farnham: our proposed two village bypass of Stratford St Andrew and Farnham (see page 35) includes a roundabout at this junction. We propose to build and open the roundabout before completion of the bypass to improve safety and mitigate the impact of construction traffic in the early years; and

A12/A144 south of Bramfield: adding a central reservation island and waiting area to increase junction capacity.


Movement of people

Reducing the amount of additional traffic generated by the movement of construction workforce remains a key part of our transport plans. In addition to the accommodation campus, our proposals to support the movement of people remain as previously presented and include:

  • two temporary park and ride facilities on the A12 to intercept traffic coming from the north and south;
  • direct bus services operating from Leiston, Ipswich and Lowestoft; and
  • bus pick-up services from Saxmundham station for workers using rail services on the East Suffolk line.


Park and ride

Our proposed locations for the park and ride facilities are Darsham in the north and Wickham Market in the south. When the construction phase is at its peak, the park and ride sites would operate seven days a week, with the movement of buses responding to the shift patterns of workers coming to and from the main development site. When no longer needed, the buildings and associated infrastructure would be removed, and the area returned to agricultural use.

Both the northern and southern park and ride sites would have:

  • parking for around 1,250 cars (40 of which would be accessible spaces and 10 would be pick-up only spaces), 10 minibuses/buses/vans, 80 motorcycles, and around 20 bicycles;

  • a secure bus terminus and parking, shelters, a welfare building (comprising toilets, bus drivers’ rest room, security and administration offices), a security building and security booth, with buildings likely to be single storey;

  • sensitive lighting that will seek to minimise the potential impact of light pollution;

  • on-site soil storage to support site restoration when the facility is no longer needed.


Additional proposals for the northern park and ride include:

  • a new roundabout on the A12 situated to the north of the existing Willow Marsh Lane junction, allowing access from the north; and

  • a 20m minimum buffer and sustainable drainage infrastructure to separate the parking area from Little Nursery woodland and nearby properties.


At Stage 4 we are proposing a slightly larger roundabout than at Stage 3. We are also proposing some changes to the development boundary to more closely align with land ownership boundaries.

Additional proposals for the southern park and ride include:

  • a postal consolidation facility;

  • a Traffic Incident Management Area to enable HGVs to be held in the event of an emergency;

  • reducing two lanes to one on the A12 northeast of Wickham Market before the northbound slip road joins the A12 (to avoid the A12 reducing from three lanes of traffic to one);

  • requesting that Suffolk County Council reduces the speed limit from 60mph to 30mph on the B1078 that crosses the A12 northeast of Wickham Market;

  • security fencing at the perimeter of the site;

  • a layout designed to maximise use of existing screening provided by woodland, and additional hedgerow planting and screening mounds;

  • external areas including roadways, footways, landscaping, surface water management areas and drainage infrastructure.


At Stage 4 we are proposing changes to the development boundary to include the B1078/B1116 roundabout to allow for pedestrian/cycle improvements within the highways land if necessary, to provide additional space for road marking and signage, and to align more closely with ownership boundaries.

At Stage 3 we proposed two options to mitigate potential delays on the B1078 between Border Cot Lane and the River Deben bridge that may occur as a result of the southern park and ride. We are now also considering an alternative approach of working with the Parish Council to bring forward a public realm improvement scheme within the public highway which would represent the first phase of implementation of the Neighbourhood Plan.
