Response

1. What works have been carried out to reduce surface water runoff being discharged into the Bourne Brook and tributary water courses from the M6 adjacent to the B4102 Meriden /Fillongley road

With regards to this question we can confirm that as part of the M6 J2-4 smart motorway scheme the following drainage works were carried out:

  • Upgrading existing drainage to accommodate the construction of Emergency Areas (additional paved areas).

  • Re-profiling of ditches within the pipe network due to increased outfall requirements where attenuation was not within the original drainage network

  • Clearing of drainage ditches where there was standing water in the M6 carriageway

For completeness, we provided the as built drawings of the drainage in this location. Please note that the document has been redacted under Regulation 13 of the Environmental Information Regulations 2004.

This potentially does not point to works that have been carried out reduce surface water runoff but they are the only works that have been carried out in this location and wanted to provide them for transparency.

With regards to your questions:

2. Were any works proposed following the smart motorway works to reduce runoff? If so what are those works and have they been implemented?

3. Please provide evidence of the volume of water and rate of discharge of runoff for the last 12 months. Are these predicted to increase and, is so, for what reason.

We can confirm that no works are proposed and the volume of water and rate of discharge of runoff for the last 12 months is not held, and by virtue of this no information is held related to predicted increase.

Therefore this information falls under Regulation 12(4)(a) of the Environmental Information Regulations 2004 for information not held, and have been refused as such.
