Tesco have built a supermarket and other buildings on a flood plain in Seaton on the Jurassic Coast. This is a very ambitious operation with all sorts of potential hazards. Tescowatch Seaton is a group of local people formed to monitor this operation and make a fuss if anything is messed up or missed out.

Dear Mr Stephenson,
Your report number 4195376/2 for Westminster Dredging Company
This report dated 7 January 2011 was posted on the East Devon planning website on 2 February, hence the delay in this enquiry.
We represent a number of our members who live in Trevelyan Road Seaton, next to the pipeline your clients are constructing to convey gravel to the Tesco construction site.Initial analysis of the pipeline system indicates that the noise levels predicted by the planning application – and even by your report - fall short of the levels likely to be generated, and that they are likely to be high enough to cause sleep disturbance to local residents.
I am writing to enquire if you feel able – on behalf of your clients – to consider the reasons for our concern and explain to us why they are unfounded.In the hope that you will agree to this request I am attaching my original critique dated 25 July 2010 and including further comments on your report below.
In section 4.1, you take a pipeline at Boscombe beach as producing sound levels similar to the Seaton pipeline.We feel this is unsound, since the Seaton gravel is coarser and has to rise 5 metres over two roads.This will require much higher volume flow rates – probably twice the settling velocity of the largest particles - than the Boscombe pipeline, which we understand did not rise to any significant degree and probably conveyed most of the solids as bedload.This means Seaton should be noisier than Boscombe, for reasons explained in the attached critique.
I should be grateful for your comments, which I shall pass on to the Trevelyan Road Residents Association.
