 The Parish Council's submission (limited to 500 words)

M4 junctions 3 to 12 smart motorway. THE SCHEME

The Colnbrook with Poyle Parish Council is the official body that represents the residents in land plans 25 and 26 south of the M4. With over 350 pages to analyse and the restriction to 500 words his can only be a summary report on the effect that the works will impact on our area.

We would however, request to take part in the examination and provide a full written response in due course.

Whilst our representation will focus on the impact on the local community during the construction phase we are also very concerned about the operational phase for one of the communities in close proximity to the M4 along the stretch at the Westfield Estate in Brands Hill.

We list below the further developments planned for this area which will have a huge impact on the community, which this report does not appear to acknowledge.

· Heathrow Third Runway as recommended by the Davies report this week.

· Construction of the Western Rail link to Heathrow (2017)

· S.I.F.E Slough International Freight Exchange

We strongly object to the London Concrete site being re-located from compound 10 to Sutton Lane compound 9. This would be extremely detrimental to residential properties, as it is located in an AQMA in which Slough Borough Council has said will exceed limits until at least 2020.

Traffic and Noise

We are concerned about the impact of increased traffic volumes, particularly at junctions 5, and 6 connecting major roads. Traffic delays/unreliability of journey times during major cultural and recreational events, and increased road traffic noise.

Permanent Stopping up of Street

It is noted that the Public right of way; Colnbrook with Poyle 2 (Old Slade Lane) commencing at its junction with public right of way Colnbrook with Poyle 6 and extending in an east to northerly direction for a distance of 305m will disappear, to be replaced with a different model.

Air Quality

Slough AQMA No. 1 – an area encompassing land adjacent to the

M4 along the eastbound carriageway between junctions 5 and 7,

and along the westbound carriageway between junction 5 and

Sutton Lane, for exceedances of annual average NO2 air quality

Objective. There is therefore the potential for adverse effects from construction and demolition dust, which will increase the annual average NO2 air quality.


Increased flood risk resulting from construction in flood plain zones, increased flood risk resulting from inadequate maintenance regime, and increased flood risk due to

Inadequate emergency response procedures.

Landowners/Businesses and compensation

Construction nuisance and impact on local residents and businesses, Impact of permanent and temporary land-take on landowners, Impact of proposals on statutory

Utilities and landowners/occupiers.


Lack of benefit to the local community from the employment or opportunities provided by the construction works.

Ecology and Nature

Impacts on nesting birds during vegetation clearance, Impacts on bats and reptiles during construction, loss of potential roosting habitat (structures and trees).

Cultural Heritage

Milestone on south eastern edge of Junction 5 will be lost.


The next steps

Once that initial assessment of issues has been done the Planning Inspectorate will write to interested parties again. Our representation will be considered by the Examining Authority.

Then all Interested Parties will be invited to attend the Preliminary Meeting and will have an opportunity to make representations about the procedure for the examination.



Highways England proposes to improve the M4 by making it a ‘smart motorway’ between Junctions 3 and 12. Smart motorways help relieve congestion by converting the hard shoulder to a running lane and using technology to monitor traffic flow and vary the mandatory speed limits to keep traffic moving smoothly. The proposed smart motorway scheme will enable proactive management of the M4 carriageway, including slip roads and motorway to motorway intersections between junctions 3 (Hayes) and 12 (Theale) on this major section of motorway.


Public Exhibitions were held during the early stages of the scheme’s development to provide members of the public and stakeholders with the opportunity to understand the smart motorway concept and our initial scheme designs of the M4.

As part of the statutory process for a Development Consent Order, as set out in the Planning Act 2008, a public consultation exercise took place on the M4 Junctions 3 to 12 Smart Motorway Scheme from 10 November 2014 until 21 December 2014. During the consultation we invited comments on the scheme proposals, the comments received and the regard given to these is set-out in the consultation report, which has now been published on GOV​.UK:


The Statutory Instrument consultation regarding the proposed use of variable mandatory speed limits ran for a period of 6 weeks commencing on 12 January 2015 and closing on 22 February 2015. All comments received were carefully considered and the responses are included in the consultation report on:
