I am making a freedom of information request in relation to the Crossrail project I would like to receive the minutes from all the liaison meeting which have been held which relate to Trinity Hall and Durward Street (E1 5BA). I would also like to receive information regarding the noise monitoring and the noise modelling that has occurred in relation to Trinity Hall and that immediate site area.

Our ref: FOI-1217-1819/GH

Thank you for your request received by Transport for London (TfL) on 31 July 2018 asking for information about Crossrail.

Your request has been considered under with the requirements of the Environmental Information Regulations and our information access policy.

However, given the extent of the information you are looking for, we are applying Regulation 12(4)(b) as we believe that the request is ‘manifestly unreasonable’ because providing the information you have requested would impose unreasonable costs on us and require an unreasonable diversion of resources.

We have identified meeting notes from 41 liaison meetings which have been held which relate to Trinity Hall and Durward Street.

We also interpreted the request for “the noise monitoring and the noise modelling” as predicted noise levels and recorded/assessed noise levels.  In addition, we have had to make some assumptions on the exact meaning of “in relation to Trinity Hall and that immediate site area”.  Monitoring equipment has not been static over the past 8 years and so the information is not all kept in one location, nor is there any recognised an agreed definition of “immediate area”. 

Our search identified circa 1500 documents, containing a huge amount of information, but without some sort of explanation or prior knowledge, we believe would be of limited value to you. We consider the burden of retrieving, reviewing and redacting the information would be disproportionate to the benefit of providing it. Therefore, due to the wide and unfocused scope of your request, we are refusing it under Regulation 12(4)(b) of the Environmental Information Regulations. If you would like to re-submit a more focused, specific request then we will, of course, consider it. For example, a request for information on a particular, specific, subject or issue over a limited period of time is less likely to raise concerns about the disproportionate effort required to answer it.

The use of this exception is subject to a public interest test, which requires us to consider whether the public interest in applying the exception outweighs the public interest in disclosure. We recognise that the release of information would promote accountability and transparency in public services and also help address your particular concerns about this issue. However, the time it would take to provide the information you have requested would divert a disproportionate amount of our resources from its core functions and on balance we consider that the public interest currently favours the use of the exception.

We will consider your request again, if you are able to narrow its scope so that we can more easily locate, retrieve and extract the information you are seeking. If you have specific questions we will be happy to consider those.

If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.

Yours sincerely

Graham Hurt
