Date published: 13 May 2019

You asked

This is an information request regarding the Ground Investigation which was carried out on the Commercial Garage premises at Croxley Car Centre. I am xxx and have been under threat of Compulsory Purchase for some years due to the then proposed Metropolitan Line Extension (formally The Croxley Rail Link). Now that the CPO is no longer going ahead, I am considering my options for developing the site and would be grateful if I could have a copy of the Ground Investigation which was carried out on my premises. xxx has suggested that I should make this request for access to the results of the Ground Investigation.

We answered

TfL Ref: FOI-0147-1920

Thank you for your request received by Transport for London (TfL) on 15th April 2019 asking for information about a ground investigation undertaken at Croxley Car Centre.

Your request has been considered in accordance with the requirements of the Environmental Information Regulations and our information access policy. I can confirm that we hold the information you require.

Typically requests for our historical ground investigation information are made through the British Geological Survey (BGS - https://www.bgs.ac.uk/). All of our data is supplied to the BGS, which then gets uploaded onto their system and can be requested by 3rd parties via the GeoRecords data request (http://shop.bgs.ac.uk/GeoRecords/?src=topNav). However, as you have requested the information directly from TfL I am supplying it to you in the attachments with this email (given the size of the attachments I will send in three separate emails – this one along with two others). Note that the full report covers a much larger area than the specific site referred to you in your request, and is in seven volumes totalling over 2000 pages, with very large file sizes. Therefore the attachments with this email are the relevant extracts relating to the specific site referenced in your request only.

Please note that the information obtained from this ground investigation has been prepared for the benefit of London Underground and its contents should not be relied upon by others without the written authority of the GI Contractor. If any unauthorised third party makes use of this report they do so at their own risk and neither LU or the Contractor owes them any duty of care or skill.

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely,

David Wells
