Settlement Deeds

Owners of properties that were predicted to experience 10mm or more of settlement received a letter dated Thursday 12 March 2015. This letter covered a commitment we made after a public enquiry about Settlement Deeds. We sent out a further letter to answer frequently asked questions.

A Settlement Deed is a formal legal document between the affected property owner and TfL and provides a personal legal undertaking from us. Property owners do not have to enter into the deed unless they choose to. Our obligations to the property owner remain unchanged even if the owner chooses not to enter into the deed.

For any other questions, email us at nle@tfl.gov.uk.

Defect surveys

Defects surveys will be done on any property predicted to experience 1mm or more of settlement. (The requirement in the Transport and Works Act Order is to carry out surveys on properties predicted to experience 10mm or more of settlement. However the London Underground Category 1 standard S1050 requires we carry out such surveys on properties predicted to experience 1mm or more of settlement.)

Owners of properties will receive a letter with at least a minimum of four weeks notice of the defects survey.

Code of Construction Practice

Part Bs

Topic plans cover noise and vibration, resource efficiency, air quality, water management, sustainable travel, archaeology and heritage, energy, and ecology.

These plans build on documents produced for the Northern line extension public inquiry and are based on best practice and legislation. The documents are known as the 'Code of Construction Practice Part Bs' and are agreed with local authorities.

The four main work site Code of Construction Practice Part Bs are:

Battersea (PDF 876KB)
Kennington Green (PDF 886KB)
Kennington Park (PDF 658KB)
Nine Elms (PDF 925KB)

The topic plans are:

Air management plan (PDF 137KB)
Ecology management plan (PDF 82KB)
Energy management plan (PDF 74KB)
Noise and vibration management plan (PDF 470KB)
Resource efficiency management plan (PDF 142KB)
Sustainable travel plan (PDF 266KB)
Water management plan (PDF 79KB)
Archaeology and heritage management plan (PDF 79KB)
Traffic management plan (PDF 5.8MB)

We discussed these plans with local communities in December 2014 through drop-in sessions, an online survey and meetings with resident groups. The amended plans above have been approved by local authorities.

TWAO

The Secretary of State for Transport decided on 12 November 2014 to make the statutory order (TWAO) that will give permission for the Northern line extension (NLE) from Kennington to Battersea via Nine Elms. The Order has been made with modifications and the Secretary of State has also decided to give permission for the project, subject to conditions. 

That decision followed a public inquiry to consider our TWAO application which ran from 19 November to 20 December 2013 and was conducted by an independent Inspector. The Inspector then submitted a report to the Secretary of State with recommendations.

See our press release on the Secretary of State's decision.

Our commitments on specific issues

We have met with resident and community groups, landowners and others with an interest in our proposals as the plans have developed. In response to their feedback we have identified a series of commitments on a number of issues and areas.

These summarise what we have said on those issues in our 'Statement of Case' and in our written evidence prepared for the inquiry. The documents below set these out:

Previous consultation results

Proposed route and location of permanent shafts

Consultations in summer 2010 and 2011 asked for feedback on four proposed routes for the Northern line extension and the locations for permanent shafts.

40,000 households and businesses along the route were invited to have their say and meetings were held for local residents, businesses and community groups.

Kennington - Nine Elms - Battersea

The majority (61%) of respondents told us their preferred route was from Kennington to Battersea, with new stations at Nine Elms and Battersea Power Station. There were high levels of support for the scheme, with the majority (87%) agreeing it will benefit the area.

Permanent shafts are needed to allow air in and out of the underground tunnels, help cool the Tube and enable emergency access to and from the tunnels if necessary. The preferred permanent shaft location is at the old distillery site, and at the Old Lodge in Kennington Park.

In the Claylands Road area, the preference is for the garages on Cottingham Road. In response to feedback, we are exploring alternative options for this site.

Lambeth Council has confirmed initial support for these sites and is working with us to agree the details of location and design.

Temporary shaft locations

Temporary shafts are required for 12-18 months for works to stabilise the ground before the tunnels can be built. In autumn 2011, 2,500 households and businesses were asked for their preferences on the proposed locations for temporary shafts in the Kennington area.

Following consultation, Radcot Street (approved by Lambeth Council) and Harmsworth Street (subject to approval by Southwark Council) are the recommended sites for the shafts.

We continue to work with councils in Lambeth and Southwark on these proposed locations.
