Northern Line Extension: construction shafts cancelled at Radcot Street and Harmsworth Street

Transport for London have let us know that they have decided it is possible to construct the Northern Line Extension without digging shafts at Radcot Street and Harmsworth Street. This is excellent news - the shafts would have caused major disruption in those streets and the streets around them.

Their alternative construction method will be to dig two 'gallery tunnels' separate from the main tunnel, from which ground stabilisation work will take place. When construction is finished the gallery tunnels will be filled in. The gallery tunnels will be dug from the permanent shafts at Kennington Green and Kennington Park - it will mean a slightly longer construction period at these sites.

This is great news for the streets around the temporary construction shafts, but Lambeth will be continuing to push TfL to minimise disruption, reduce noise from construction and the trains, and agree the best possible plans for reinstating Kennington Green and Kennington Park.

 
Email from TfL:

I am writing further to our recent application for a Transport and Works Act Order (TWAO) and the expiry of the representation period to update you that the Secretary of State for Transport has made a decision to hold a public inquiry to consider our application (see footnotes for details of the process) and to advise you of some amendments we have made to the proposals for the Northern line extension (NLE).

These changes have been made in response to consultation feedback, following further engagement with the local authorities of Southwark and Lambeth and the completion of further engineering feasibility work.

The TWAO application includes powers for two potential construction methods (via underground ‘gallery’ tunnels or temporary surface shafts at Harmsworth Street and Radcot Street) to connect the old tunnels to the new NLE tunnels and to stabilise the ground.  Both of these have been assessed in the Environmental Statement (ES).

Following further feasibility work, a decision has been taken by TfL to remove the temporary shafts proposed at Harmsworth Street and Radcot Street on the basis they are no longer required.  This means that no above ground works will be undertaken at either of these locations and construction works will be progressed from the proposed worksites at Kennington Park and Kennington Green instead. The impacts of this change have already been assessed and reflected in the ES.

Factsheet A:connecting the extension to the existing Northern line and stabilising the ground, provides more information about the gallery tunnel construction approach.

Consultation in autumn 2012 on the proposals for a permanent shaft and head house at Kennington Park demonstrated some support for the inclusion of a new community building adjacent to the proposed head house.

Following discussions with Lambeth, TfL has agreed to remove the community building from the scheme on the basis Lambeth would prefer to support existing community facilities in the surrounding area. TfL will amend its proposals for the area by increasing landscaping in the part of the park which was previously taken up by the community building.

With regard to the bee keeping and other community activities carried out by Bee Urban at the Old Lodge site, Lambeth and Friends of Kennington Park are in discussion with Bee Urban about agreeing a new site elsewhere in the park.  This would provide facilities for Bee Urban on a more permanent basis irrespective of permission being granted to build the NLE and in advance of the start of construction.  It would also avoid Bee Urban having to move twice.

The changes to the scheme set out above will be reflected in an addendum to the NLE TWAO environmental statement which is intended to be submitted to the Secretary of State for Transport on 27 August 2013. In line with the TWAO process, the addendum will be subject to a further six week representation period where comments can be made to the Secretary of State for Transport.  We will contact you again with details of where the document can be viewed and how to make a representation.

Yours sincerely

Richard de Cani
Transport for London


Next steps

The Secretary of State announced on 16 July 2013 that a public inquiry will be held to consider our application.  This is likely to start this autumn.

Those who have objected to the scheme should have been notified of this decision by the Department for Transport and asked if they would like to take their representations and comments further and present evidence verbally at the inquiry.  If this is something you would like to do, you will be asked to provide a written statement (statement of case) to outline the full details of the case that you want to present to the inquiry.  This should be received by the Secretary of State and TfL within six weeks of the announcement of the inquiry (so by 27 August 2013).

As the applicant, TfL will also be required to submit a statement of case.

Northern Line Extension: drop in event for Kennington Green and 373 Kennington Road

Drop in event to consider proposals for a permanent shaft and head house at Kennington Green and an alternative location at 373 Kennington Road

Date: Thursday 25 July

Place: Durning Library
167 Kennington Lane
SE11 4HF

Time:  3.30pm – 8pm

TfL recently submitted an application to the Secretary of State for Transport for a Transport and Works Act Order (TWAO) to build and operate an extension of the Northern line to Nine Elms and Battersea. Theit submission marked the beginning of a statutory consultation period which closed on 18 June 2013.

Their submission includes proposals for a permanent shaft at Kennington Green to allow air in and out of the proposed new northbound underground tunnel, to help cool the tube and extract smoke in the unlikely event of an emergency.  The shaft itself will be located underground in the green, but an above ground structure is required (known as a head house) to house maintenance equipment and vents for the shaft.  This would be located at the corner of Montford Place and Kennington Road within the Beefeater Distillery site. Full details of the proposals are available to view attfl.gov.uk/nle.

Some responses to the consultation put forward an alternative location for the shaft and head house at 373 Kennington Road.  This site is currently occupied by an artist run space called Space Station 65, comprising offices and studios for creative industries and borders with properties on Aulton Place and 377 Kennington Road.

This event will address in detail some of the key issues raised specific to the Kennington Green site, consider the alternative proposals put forward for 373 Kennington Road and provide a platform for further dialogue and discussion.  Senior representatives from the NLE project team will be in attendance on the day.

TfL meetings about Northern Line Extension's effects on Kennington Park and Kennington Green

Meeting to discuss design considerations for the proposed permanent shaft at Kennington Park

This meeting with representatives from TfL, Lambeth and Southwark councils, local community groups and Friends of Kennington Park will discuss the design of the proposed permanent shaft building (head house) at Kennington Park for the proposed Northern line extension.  The meeting will also be attended by TfL’s heritage and urban design leads and John MCaslan & Partners, the architects commissioned by TfL to design the above ground structures for the proposed extension.

The meeting will take place on Wednesday 16 January at St Agnes Church Hall, St Agnes Place, Kennington from 6:30 – 8pm.

The feedback from the NLE consultation about the design of the proposed head house at Kennington Park will be shared and there will be discussion of further design considerations before TfL progress with more detailed plans ready for submission as part of their application for a Transport and Works Act Order.

This is a follow up to a meeting held at the Café in Kennington Park back in October, where initial ideas shaped the indicative designs for the head house currently being consulted upon.

Council listening to residents' Northern Line Extension concerns

Lambeth Council have appointed tunnelling experts Ramboll as independent technical consultants to examine Transport for London's plans for the Northern Line Extension, which are are progressing quickly.

At an exhaustive three hour meeting this evening, chaired by London Assembly Member Val Shawcross, experts from Ramboll listened to the detailed concerns that residents have about the construction and operation of the Northern Line Extension.

Issues included:
- the exact location of the construction shaft in Radcot Street (not yet decided)
- the effect on adjacent properties
- air quality next to the shaft
- parking during construction (the gin distillery was suggested as a possible site for parking)
- traffic circulation through 'Methravia' during construction
- size and quality of the construction vehicles
- hours of construction work
- noise - construction of tunnels and operation of the trains
- capacity of Kennington station - for additional trains and additional passenger interchange
- boundary issues - discussions with Southwark
- process for monitoring any settlement or damage caused by tunnelling
- the need for maximum noise mitigation around the 'Kennington Loop' - where the NLE will meet the existing track and be at its most shallow - and the need for the existing track on the Loop to be upgraded to reduce noise disruption.
- how to manage Kennington Park during construction, reproviding the dog exercise area and ensuring community projects aren't forced to close.
- which shaft site has been decided for Kennington Green - the distillery is preferred and residents want the trees protected
- the proposed permanent shaft at Claylands Green which is fiercely opposed by local residents there and TfL are now examining whether other options are possible.
- what noise and effect the permanent ventilation shafts will have.

There was a clear consensus from residents and councillors that
- Lambeth Council must demand the minimal construction disruption to residents possible.
- Lambeth Council must insist on the highest possible noise mitigation work for the operation of the trains.
- Lambeth Council must specify construction techniques which are least noisy and least disruptive to residents.
- Ramboll need to examine TfL's plans in great detail and not be afraid to challenge them to improve the project's effects on Lambeth's residents.

Councillor Mark Harrison said 'the meeting was a really useful and detailed airing of all the many concerns that Lambeth residents have about the Northern Line Extension. Now independent experts Ramboll can go away and examine TfL's plans in detail and get answers to the questions raised'.

Support the fantastic Friends of Kennington Park

Yesterday was the AGM of the Friends of Kennington Park, and a celebration of the tenth anniversary of the group.

It's been another really successful year, with the Friends bringing more additional investment and planning more ambitious projects to improve the park.

This year that has included raising more than £2000 to clean and restore the war memorial, introducing three new benches, new signage and nesting boxes for birds and bats.

The Friends have also embarked on an application to the Heritage Lottery Fund to restore the historic flower garden, and will be contributing to Lambeth Council's 10 year masterplan for the park.

The Friends are always looking for new members and people willing to volunteer their time with various projects - be they gardening, fundraising, administration, or any positive project to enhance the park. Please join as a member at their website.

At yesterday's meeting Kate Hoey MP suggested that the Friends assist residents around Kennington Green in trying to improve that small green space - we hope this suggestion might be taken up!
