Minutes:
Mr Protheroe, the Highways
England (HE) Representative began his presentation and thanked the
Task Force for inviting HE to the meeting, as he felt it was a good
opportunity to hear feedback and concerns. He began by outlining
the Development Consent Order (DCO) process and confirmed that HE
were intent on submitting the DCO by the end of October. He added
that the team were currently reviewing results from the design
refinement consultation, which they would need to complete first
before they could submit DCO. He explained that once the DCO was
submitted the Planning Inspectorate (PINS) had 28 days to review
and consider if the submission met the required government
standard. He explained that if the submission did meet that
standard then the next stage would be the pre-examination and
examination phases, during which key stakeholders would be able to
challenge HE on the scheme and HE would have to explain how the
scheme was developed. He stated that HE, at this phase, would set
out the necessary impact assessments, including for both
construction and route operation. He added that after the
examination phase, PINS would make its recommendation regarding the
route to the Minister, for him to make the final decision. He
mentioned that legal challenges could then be submitted after the
Minister’s decision announcement.
Mr Protheroe moved on to outline the key factors included in the
design refinement consultation, which included a reduction in the
size of the development boundary, minor highway design changes,
alignment changes and bridge changes. He added that the
consultation also included more detailed information regarding how
the design of the route would impact non-motorised users, including
horse riders. He stated that utility diversions had also been
changed in the design refinement consultation, as the utilities
companies had worked to provide more finalised studies of their
sites. He commented that the consultation also included more
developed landscape proposals, as well as some ecological
mitigation. Mr Protheroe described how the COVID pandemic had
impacted the consultation as no in-person events could be held, and
the majority of the deposit locations had closed, so the team had
followed a ‘digital first’ approach which did include
some telephone and postal consultation. He stated that HE had
worked hard to continue their consultation whilst following
government guidelines, and the digital first approach had worked as
the number of website hits had increased.
Mr Protheroe then explained how the development boundary had
changed at design refinement consultation as 45% less houses were
affected, a drop from 270 to 150 properties, and 12.5% less land
was needed which equated to 26.2km 2. He added that the
number of overhead lines needing to be moved had also decreased,
and noise barriers were being designed to mitigate some of the
noise from the road, and highlighted that these were being
developed, including their height and location, by HE contractors,
although they had to meet HE standards. He stated that some of the
barriers would be made from wood, but others would be made from
newer materials such as recycled plastics, or earth bunds. Mr
Protheroe then explained in detail the locations of the noise
barriers, such as in Tilbury, the junction with the A13 and
Ockendon. Mr Protheroe then explained in detail the location and
height of false cutting and earth bunds, such as in Chadwell St
Mary and South Ockendon. He then explained the locations of
construction compounds, including the Lakeside compound, and
described how these had not been moved since statutory
consultation, but had been reshaped to avoid an archaeological
site. He then described and summarised the feedback from the
supplementary consultation and design refinement consultation. He
stated that some of the concerns from the supplementary
consultation had been reiterated at design refinement, including
lack of technical engagement, problems with the emerging Local
Plan, design quality and safety. He highlighted specific comments
made at consultation such as the environmental impact of each
change, the need for detailed mitigation information, and design
refinements for non-motorised users.
The Chair thanked HE for their presentation and began the debate.
Councillor Shinnick questioned the size of the proposed
traveller’s site and asked if it would house more travellers.
Mr Protheroe responded that the residential location was bigger as
more land was required for environmental mitigation, but the number
of people living there would not increase as there would still be
21 pitches. The Assistant Director LTC added that the footprint of
the traveller’s site also needed to increase to meet current
fire safety requirements. Councillor Muldowney then questioned the
feedback from the design refinement consultation on the location of
the proposed traveller’s site. Mr Protheroe responded that
the team were currently working through consultation responses, so
no detailed data was currently available.
The Resident Representative questioned why the noise barriers would
be made of wood or other similar materials, when there was more
modern sound absorbing material available. He also questioned what
the statutory requirements were for noise reductions and
mitigation. Mr Protheroe responded that lots of material was
assessed for noise reduction abilities, but HE’s contractor
would have to adhere to standards set out in the Environmental
Statement. He added that noise barriers were designed to reflect
rather than absorb noise, and surveys would be carried out to
ensure that all noise barriers met the required standard. Mr
Protheroe added that monitoring would be undertaken both during
construction and once the route was opened to show their
effectiveness, and wooden noise barriers were a well-established
means of noise reduction. The Resident Representative queried if HE
had taken into account the maintenance of the noise barriers. Mr
Protheroe stated that any false cutting or planting would not be
right up to the noise barrier to ensure that proper maintenance
could be undertaken. Councillor Muldowney queried how building a 6m
high noise barrier would affect residents who lived near them. Mr
Protheroe replied that the barriers would provide necessary noise
protection, but the visual impact would be assessed in the
Environmental Statement. He added that some of the noise barriers
would be large structures, and it would depend on the outlook of
the house on how much impact they would cause.
The Thames Crossing Action Group (TCAG) Representative queried map
book three of the design refinement consultation documents and
asked for an explanation regarding the removal of the false
cutting, to which Mr Protheroe replied that he did not have the
detail but would respond to the query via email. The TCAG
Representative then questioned the effectiveness of the noise
barriers. Mr Protheroe responded that HE created noise surveys and
models, which reported what the noise pollution would be without
any mitigation, and with the proposed mitigation to show the
effectiveness. He stated that the level of noise decreased quickly
the further you were from the route, but clarified that the
Environmental Statement would be provide a full report.
Councillor Rice stated that the route came very near to houses on
Brentwood Road and asked if the route could be moved further west,
away from centres of population, which would reduce the nuisance
for residents and the need for noise barriers. Mr Protheroe
responded that the final location of the scheme was still being
developed and lots of work would be undertaken at DCO submission
and examination. He added that HE would have to prove that the
scheme was appropriate at DCO and examination. The Assistant
Director LTC added that as the route was nearing DCO submission,
the ability to change or move the scheme was slim. Councillor
Spillman stated that the UK and Thurrock were currently
experiencing a bio-diversity crisis and asked how HE would measure
the impact of the scheme on bio-diversity across the borough, and
what mitigation or projects could be added to improve
bio-diversity. Mr Protheroe replied that the impact on
bio-diversity would be reported in the Environmental Statement and
follow HE’s design manual for roads and bridges, which
included desktop and physical surveys to understand bio-diversity
and the impact on flora, fauna and ecology. He added that any
mitigation and species translocation would be included in the
Environmental Masterplan, and final bio-diversity calculations had
not yet been finalised. He stated that it would be difficult for a
new scheme such as this to have a net positive bio-diversity
outcome on site, without the use of bio-diversity credits away from
site, but HE were currently working on different proposals and
mitigation measures. The Assistant Director LTC added that HE only
had to mitigate significant loss of bio-diversity.
The Chair questioned the number of DCO’s currently being
submitted such as Bradwell 2 and the new theme park in Kent, and
queried whether or not there would be enough construction workers
in the area to fulfil the requirements of all three projects, if
they were successful. Mr Protheroe responded that HE had recognised
the potential risks and issues with numerous major schemes being
constructed at the same time. He stated that ideally HE wanted to
draw as many local labourers into the scheme, and that HE had been
working with SME’s to align them with the scheme and maximise
the likelihood of gain for the local community. The Chair then
asked how, if HE had to bring in external construction workers,
these would be managed and housed, and how HE would ensure they did
not impact upon local residents. Mr Protheroe stated HE were
currently assessing the location of the main works compound and how
construction workers would access these sites. He stated this would
be communicated through the Construction Code of Practice and
outlined in the DCO. He stated that as some parts of the
construction would be operating 24 hours a day, some construction
workers would need to live on site. The Assistant Director LTC
added that the Council were not supportive of temporary mobile
homes for construction workers across the borough, and felt that
external workers might have an impact on the ability of local
residents to access services such as temporary accommodation. She
added that Thurrock were trying to promote green travel, for
example using the new Stanford-le-Hope station as a transport hub,
so workers from London and Southend could be bussed directly from
the station to the site.
Councillor Muldowney questioned the effectiveness of the air and
noise pollution modelling, and whether or not any more modelling
would be taking place. Mr Protheroe responded that air quality and
noise modelling had been created by using the traffic model, which
now used phone data to understand traffic patterns. Mr Protheroe
confirmed that traffic modelling had previously used postcard and
survey data, but current traffic modelling provided more robust
data. He explained that HE also used webtag guidance on air
quality, and this would be based on traffic flow modelling, which
had not yet been completed. He added that when the Environmental
Statement was published it would include the methodology of the
traffic modelling, and this would be in accordance with government
guidance. Councillor Muldowney questioned when the traffic model
had been updated. The Assistant Director LTC responded that the
traffic model had been recently updated and the cordoned model had
been shared with the Council. She added that air quality near the
proposed route would deteriorate in some areas, but would not be
allowed to deteriorate beyond government limits. She mentioned that
the Council would be monitoring and measuring air quality during
the routes construction and once it had been opened, as modelling
could not accurately predict traffic patterns. She commented that
as the route was due to open in 2027/28 the hope was that the
number of green vehicles would have increased, although the Council
were concerned regarding the number of HGVs which would be using
the route, due to the three international ports.
Councillor Spillman stated that due to the COVID pandemic the
number of car journeys being made had significantly reduced, and
whether this would influence the scheme. He also asked if COVID
would influence the cost-benefit ratio of the scheme. Mr Protheroe
stated that the traffic model had not included COVID, but agreed
that the amount of traffic had decreased during the pandemic,
although the longer term effects of COVID on traffic was not yet
known. He added that any clarification regarding the impacts of
COVID would be discussed during the examination phase.
The Resident Representative questioned the benefit-cost ratio of
the scheme. Mr Protheroe responded that the benefits of the scheme
would be shared at Council and ward level once the DCO had been
submitted. He stated that one of the local benefits would be the
local construction workers who would be used for the scheme, which
would increase capital in the local economy, and added that the
scheme would also improve congestion on the local road network due
to the decrease in congestion at the Dartford Crossing. Mr
Protheroe added that the DCO would outline current cost estimates
and any economic benefit would be outlined in the Economic
Assessment Report. The TCAG Representative asked for information on
the Mardyke Viaduct, as no visual designs had been released. The
Assistant Director LTC stated that the designs had been shared in
the design consultation, but the structure had changed to two,
short viaducts with an earthwork embankment as separation. Mr Hodge
stated that the viaduct would be 11.5metres high, with ground level
at 3.5metres high, giving 8metres clearance for pedestrians and
non-motorised users. He added that the two viaducts would be
50metres in length with an embankment in between, and this was
outlined in map book three on sheet 15. He stated that the
reduction in height was due to a number of factors including
commercial pressures and budgetary constraints. Mr Hodge added
flooding had been considered, as well as the overall benefit the
viaduct would provide for the scheme.
Councillor Muldowney queried the number of apprenticeships that
would be provided by the scheme, and whether HE could provide an
update. She added that there was currently 12% youth employment,
which could rise due to the COVID pandemic, and whether HE were
working to improve training opportunities. Mr Protheroe replied
that lots of work was being undertaken and meetings were taking
place between HE and local SMEs, and the IT model that had been
used during the Olympics was being adopted to get main works
contractor’s connections. He added that the government had
set a 5% target on apprenticeships which HE would meet and were
planning to exceed.
