Sainsbury’s have a planning Application that is in a period of consultation that will end on the 15th March. They plan two high tower blocks on lans above or adjacent to the proposed tunnelling of the Bakerloo line Extension and NXG Station. We would like to request an FOI regarding TFL’s research and analysis into the impact of the foundations of these towers and development. The research would focus on two questions: 1. Would large foundations as seen in the Sainsbury’s and Mount Anvil (S/MtA) application compromise or obstruct the preferred tunnelling route (were it to be given planning permission and built)? 2. a) Has there been a TFL case study modelled on the impact of the S/MtA on TFL’s proposed plans were they to be accepted? b) Will tunnelling beneath the towers (were they to be given a green light) substantially complicate and financially compromise the delivery of the BLE?

In accordance with our obligations under Data Protection legislation some information has been withheld from the attached correspondence, as required by regulation 13 of the EIR. This is because disclosure of this personal data would be a breach of the legislation, specifically the first principle of Article 5 of the General Data Protection Regulation which requires all processing of personal data to be fair and lawful. It would not be fair to disclose this personal information when the individuals have no expectation it would be disclosed and TfL has not satisfied one of the conditions which would make the processing ‘fair’.

This exemption to the right of access to information is an absolute exemption and not subject to an assessment of whether the public interest favours use of the exemption.

If this is not the information you are looking for, or if you are unable to access it for some reason, please feel free to contact me.
