Pinewood Studios Development Framework and Five Points Roundabout
Supplementary Environmental Statement
1 Introduction
1. This Supplementary Environmental Statement (SES) has been prepared by Ove
Arup and Partners Ltd (Arup) on behalf of Pinewood Studios Ltd (PSL). It
supplements the original Environmental Statement (ES) [CD09] prepared by Arup
in February 2013 and should be read in conjunction with that document.
2. It identifies any significant differences in environmental impact between the
Pinewood Studios Development Framework (PSDF) and Five Points Roundabout
(FPR) application scheme submitted to South Bucks District Council (SBDC) in
February 2013 and the amended PSDF scheme that is subject to the planning
appeal APP/N0410/A/13/2199037 lodged on 31 st May 2013.
3. PSL proposes to amend the PSDF scheme to enable the proposed emergency
access to be formed onto Sevenhills Road to be used as both an emergency access
and a secondary controlled vehicular access for employees. This will be able to
operate as an emergency access unless and until such time as future traffic
monitoring and management criteria thresholds are exceeded and require it to be
used as a secondary controlled vehicular access.
4. This SES assesses the effects of implementing the change (if triggered at a future
date) from emergency-only to secondary controlled vehicular operational use of
the proposed Sevenhills Road access, in conjunction with the delivery of the
already approved Sevenhills Road / Denham Road signalised junction
improvement scheme and the FPR improvement.
5. Should the requirement for the secondary controlled vehicular access onto
Sevenhills Road be triggered, the environmental effects resulting from the
amended PSDF development will be as set out within this SES. If however the
secondary access was not to be triggered, the effects will be unchanged from those
assessed within the original ES. In any event, the majority of the chapters of the
original ES are unaffected by the proposed scheme amendment.
6. This SES also identifies relevant changes in the baseline conditions since the
preparation of the original ES.
7. In providing further information to the submitted ES, this SES has been prepared
in accordance with the Town and Country Planning (Environmental Impact
Assessment) Regulations 2011 (SI 2011 No. 1824). The methodology used for
undertaking this SES is also consistent with that of the original ES.

2 Proposed Development
8. The original ES described the PSDF and FPR application scheme proposals at
Chapter 4.
9. The planning applications for the PSDF and FPR development proposals were
submitted to SBDC on 1st February 2013. They comprised:
1) PSDF outline application : SBDC ref. 13/00175/OUT
‘Reconfiguration and expansion of facilities for screen based media, including
film, television and video games and associated services and industries,
comprising: demolition of existing outdated accommodation; erection of new
stages, workshops, office accommodation, demountable modular buildings,
entrance structures and reception and security offices, gas CHP energy
centre, underground waste water treatment plant, recycling facilities, backlots
and film streetscapes; external film production; creation of a new vehicular
and pedestrian access from Pinewood Road, emergency access from
Sevenhills Road, access roads within the site 1 , surface and multi-level car
parking; and associated landscaping and ecological habitat creation works’.
2) FPR full application : SBDC ref. 13/00176/FUL
‘Highway improvements to the Five Points Roundabout’.
10. The PSDF application was determined by SBDC on 15th May 2013 and an appeal
(APP/N0410/A/13/2199037) was subsequently made to the Secretary of State
against SBDC’s decision in May 2013.
11. The FPR application was granted full planning permission by SBDC on 26th July
2013.
1 In respect of access, full approval is sought for the means of vehicular access from Pinewood Road and for secondary controlled
vehicular access from Sevenhills Road. All other aspects of access are reserved.

3 PSDF Scheme Amendments
12. PSL proposes to amend the PSDF application scheme to enable the access to be
modified on Sevenhills Road to be used as both an emergency access and a
secondary controlled vehicular access for employees, but only on the condition
that it becomes necessary to do so. The tests of whether it will become necessary
to use the access as a secondary controlled vehicular access are contained within a
‘monitor and manage’ approach as agreed with in principle by Bucks County
Council and as set out below.
13. If its use as a secondary controlled vehicular access is required, the Sevenhills
Road access will comprise the priority junction shown originally in the scheme
proposals as the emergency only access. It will be equipped with a security (card
reader) entry control system and provided with appropriate signage. A plan of the
proposed access layout for secondary controlled vehicular use is shown in
Appendix A of this SES.
14. It remains the case that the main operational and construction access to the PSDF
site (East and West Areas) will be from Pinewood Road.
15. The following has been agreed between Buckinghamshire County Council (BCC)
and PSL as the basis of a 'monitor and manage' approach:
• Traffic flows generated as a result of the PSDF proposals and journey times
through Iver Heath would be monitored during agreed periods;
• The trigger for further action will be if the traffic flows contained within the
TA and journey times produced by agreed paramics modelling, are exceeded
on an agreed number of occasions;
• If the triggers are exceeded on this agreed basis, then PSL would introduce
controlled use of the Sevenhills Road access to provide a secondary vehicular
access for use by employees accessing the PSDF development (East
Area). The form and extent of the access will already have been approved
within land which is either adopted highway or within the control of PSL;
• This controlled secondary use of the proposed access will only be
implemented if (in addition to the above triggers being exceeded) BCC has
first completed improvements to the Sevenhills Road/Denham Road junction
as authorised by planning permission ref. 09/00708/FUL. These improvements
will (if undertaken by BCC) be funded by a contribution from PSL.
16. In order to reflect the above scheme amendments, the planning application
description of the PSDF development is therefore proposed to be amended as
follows:
‘Reconfiguration and expansion of facilities for screen based media, including
film, television and video games, and associated services and industries,
comprising: demolition of existing outdated accommodation; erection of new
stages, workshops, office accommodation, demountable modular buildings,
entrance structures and reception and security offices, gas CHP energy
centre, underground waste water treatment plant, recycling facilities, backlots
and film streetscapes; external film production; creation of a new vehicular
and pedestrian access from Pinewood Road, emergency access from
Sevenhills Road, a new access from Sevenhills Road for use as both an
emergency access and a secondary controlled vehicular access, access roads

within the site, surface and multi-level car parking; and associated
landscaping and ecological habitat creation works’.
17. The use of the proposed access for both emergency use and secondary controlled
vehicular access purposes will involve no changes to works within the highway
boundary with respect to the following:
• the position of the access onto Sevenhills Road; and
• the number of trees and amount of hedgerow to be removed to accommodate
the works.
18. The access to Sevenhills Road will be able to be implemented for emergency use
from first occupation of the PSDF development. Should the commitment to use
the access for secondary controlled vehicular use be triggered, it will be upgraded
by undertaking the following works:
• grasscrete surfacing to be upgraded to tarmac surfacing; and
• position of the gate (relating to its use as an emergency access) set back into
the site by a further 10m and replaced by a swipe card operated access control
barrier.
19. Construction works required to upgrade Sevenhills Road from emergency access
to the proposed secondary controlled vehicular access will entail a small number
of construction vehicles over a short period of time expected to be up to four
weeks. Given that the upgrade works would not coincide with the main works to
be undertaken for the PSDF and FPR sites, the overall effects of construction are
not considered to be significant. The same general construction mitigation
measures as set out within a Code of Construction Practice (CoCP) and agreed
beforehand with SBDC will in any event reduce construction effects such that
they are not significant.
20. It is estimated that the operation of a secondary controlled vehicular access onto
Sevenhills Road for staff entering the PSDF site would generate 1,260 two-way
staff vehicle movements on Sevenhills Road between the controlled hours of
07:00 and 19:00.. This traffic comprises the vast majority of staff movements
travelling between the PSDF site and the A40/A412 Denham Roundabout. Traffic
entering or leaving the PSDF site outside of the controlled hours would be
restricted to Pinewood Road
21. It is not possible to set out timescales for the implementation of a secondary
access, as it will only be delivered if and when the ‘monitor-and-manage’ scheme
requires. As such, there is the potential that the use of the access onto Sevenhills
Road as a secondary controlled vehicular access may never be triggered; in which
instance the environmental effects of the PSDF scheme would be unchanged from
those set out within the ES
22. For the purposes of this SES however, the assumed construction of the PSDF
scheme and FPR improvements will be complete by no later than 2031 and
assuming the access amendment is triggered, the secondary controlled vehicular
access onto Sevenhills Road would be implemented no later than two years
following full occupation i.e. 2033 as a worst-case assessment year.
23. As noted above, in order for the proposed Sevenhills Road access to be used as a
secondary controlled vehicular access for staff, the already approved improvement
works to the Sevenhills Road/Denham Road junction will need to be implemented

by BCC. That scheme comprises upgrading of the junction geometry and the
change in junction control from the existing priority junction arrangement to
traffic signals. The typical method of construction for the Sevenhills
Road/Denham Road junction works was described in the previous proposals for
Pinewood Studios, known as ‘Project Pinewood’ in its ES Volume 3, Appendix (i)
Part 1 (Code of Construction as follows:
• construction of the majority of the roundabout to the south-east of Denham
Road;
• installation of the road alignment to the Sevenhills Road/Denham Road
(south) utilising a four-way traffic system to control traffic in the
temporary condition; and
• completion of the roundabout layout, including the construction of kerbs
and road make up on the Sevenhills Road/Denhan Road (north) section.
24. The works would be expected to be undertaken in a matter of weeks and therefore
effects associated with construction would be in the very short-term.
25. Whilst a S106 Agreement ties the implementation of the above junction
improvement to the implementation of the previous proposals (ie Project
Pinewood) BCC has agreed in principle to remove the linkage.
26. All other aspects of the PSDF scheme proposals remain unchanged from the
original planning application and ES submitted to SBDC in February 2013.

4 Status of the Original Environmental
Statement
4.1 Introduction
27. The implications of the PSDF scheme amendments for the conclusions of the
original ES in terms of their environmental significance, have been carefully
considered by each of the technical authors of the chapters of that document.
28. On this basis, the following chapters of the original ES are supplemented by this
SES:
• Development proposals
• Transport
• Air quality
• Noise and vibration
• Ecology and nature conservation
29. As described in Section 3, construction works required to amend the use of
Sevenhills Road to a secondary controlled vehicular access will be minor. The
physical changes to the road as described in para 18 are modest and therefore will
have no effect with respect to a number of environmental topics assessed in the
ES. The following chapters of the original ES are therefore unaffected by the
PSDF scheme amendments and submission of Supplementary Information:
• Application sites and surroundings
• Indicative phasing and construction
• PSDF scheme alternatives
• Ground conditions and contamination
• Heritage assets
• Landscape and visual
• Socio-economics
• Light obtrusion
• Waste
• Water resources
4.2 Baseline conditions
30. Baseline conditions at the PSDF site and surrounding area were described in the
original ES.
31. While the East Area has remained unchanged from the conditions identified in the
original ES, there have been two recognised changes in the conditions on the West
Site; both of which relate to built heritage matters. These are:

Supplementary Environmental Statement
1) Heatherden Hall was added to the List of Buildings of Special Architectural or
Historic Interest by the Secretary of State on 27 th August 2013. The building is
now listed at Grade II. The Main Administration Building remains unlisted.
2) Heath Farm has been demolished.
32. Whilst Heatherden Hall was not a designated heritage asset at the time of the
preparation of the original ES in February 2013, PSL was aware of an application
made by SBDC for it to be listed. A cautious approach was therefore adopted in
the original ES in terms of assessing the heritage effect of the PSDF scheme on
Heatherden Hall and the assessment was carried out on the basis that the building
was already a listed structure. As such Heatherden Hall is assessed as being of
medium (regional) value. The fact that Heatherden Hall now is statutorily listed
therefore has no change on the assessment of the PSDF scheme and nor is the
significance of the Hall impacted by the proposed PSDF scheme amendment. The
conclusions of Chapter 10 of the original ES in respect of Heatherden Hall
therefore remain unaltered.
33. The West Area of the PSDF site contains a number of buildings of undesignated
heritage interest which will be subject to demolition under the PSDF scheme and
upon which the PSDF scheme amendments have no bearing. Heath Farm was
identified for demolition and assessed as only having low value in the original ES.
Its loss was judged to be slight and not significant.
34. Heath Farm was able to be demolished under the extant planning permission
04/00660/OUT granted on 12th April 2006 and was not subject to any predemolition
conditons. The conclusions of Chapter 10 of the original ES in respect
of the demolition of Heath Farm, having now taken place, therefore remain
unaltered.
4.3 Cumulative assessment
35. The secondary controlled vehicular use of the Sevenhills Road access will only be
implemented if the improvements to the Sevenhills Road / Denham Road junction
have first been completed as approved by planning permission ref. 09/00708/FUL.
36. The cumulative effect of theses permitted junction works in combination with the
amended PSDF and FPR proposals has therefore been considered in each of the
environmental topics covered in this SES.
37. Given the proposed sequencing of the operation of the Sevenhills Road as a
secondary controlled vehicular access as described in paras 15 and 23, the
assessments capture the cumulative effects of the Sevenhills Road access in
combination with the approved Sevenhills Road/Denham Road junction works.

5 Transport
5.1 Introduction
38. This section supplements the relevant parts of the ES Transport chapter that have
changed as a result of the PSDF scheme amendments. It provides an assessment
of the potential transport effects associated with the provision of a secondary
controlled vehicular access via Sevenhills Road, and for clarification, includes a
comparison with the impacts associated with the PSDF scheme without the
secondary controlled vehicular access (as set out within the ES).
39. All references to figures and appendices are to those found in the STA unless
specifically referenced as being part of this section.
5.2 Relevant Elements of the Proposed Development
40. The PSDF application seeks approval of the proposed means of vehicular access
from the adopted public highway. All other matters are reserved for subsequent
approval.
41. In parallel with the PSDF application a second planning application was
submitted for improvements to Five Points Roundabout (FPR) at the southern end
of Pinewood Road. The application (Ref: 09/00707/FUL) was granted planning
permission in July 2013. The issues raised by these improvements are relevant to
a number of sections of this SES and are therefore considered as an integral part
of it.
Access Strategy
Vehicles
42. The access strategy set out within the ES will be retained; however the proposals
have been amended to allow for the provision of both an emergency access and a
secondary controlled vehicular access via Sevenhills Road in place of the
emergency-only access previously proposed.
43. This SES assesses the effects of the secondary controlled vehicular access from
Sevenhills Road being used for employees between the hours of 07:00 and 19:00.
44. To allow use of the secondary controlled vehicular access by employees, BCC
will first have to complete improvements to the Sevenhills Road/Denham Road
junction as authorised by Planning Permission 09/00708/FUL Therefore the
assessment in this section assumes implementation of those works.
Pedestrian and Cyclist Facilities
45. The proposed pedestrian and cyclist facilities remain unchanged from those set
out within the ES.

Parking
Car Parking
46. The proposed car parking remains unchanged from that set out within the ES.
Cycle Parking
47. Cycle parking facilities will remain unchanged from those set out within the ES.
Sustainable Transport Strategy
48. The Sustainable Transport Strategy (STS) remains unchanged from that set out in
the ES.
5.3 Scoping and Consultation
49. The details of the scoping and consultation undertaken with key stakeholders is
included within the ES. Since the submission of the ES, further meetings and
discussions have taken place with Buckinghamshire County Council (BCC) to
agree the scope of the revised access proposals and assessment of their impacts.
5.4 Methodology
50. The methodology used in this Supplementary ES is as contained within the ES.
5.5 Assumptions and Limitations
51. The assumptions and limitations of this assessment are set out within the ES. In
addition to those set out in the ES, in assessing the impacts of the secondary
controlled vehicular access, this assessment assumes the advance implementation
of the Sevenhills Road/Denham Road signalised junction improvement scheme.
5.6 Baseline
52. The Baseline conditions remain unchanged from those identified within the ES.
5.7 Assessment
53. The summary of the secondary access impacts, and comparison with the ES, are
provided at the beginning of the following section, followed by the full detailed
impact assessment.
Assessment Summary
54. Table 1 below summarises the overall predicted impacts reported in this chapter.

55. The traffic flows across much of the network will remain the unchanged from
those set out within the ES; therefore this section identifies the differences for
ease of reference.
56. PSDF with the proposed secondary controlled vehicular access to Sevenhills Road
will result in changes to the traffic flow on five links when compared to the PSDF
with emergency access only onto Sevenhills Road. The traffic flows on the
remaining 17 links assessed remain unchanged from those set out within the ES.
The five links subject to changes in traffic flow are as follows:
• Sevenhills Road (between Living props and Sevenhills farm)
• A412 Denham Road (near Bangors Road Nth)
• A412 Church Road (between Five points and Warren house)
• Pinewood Road (near Park Lodge)
• Pinewood Green (link to Pinewood Road)
57. Table 2 below sets out the changes in traffic flows on the above links as set out
within the ES and within the following sections of this SES, and identifies the net
change in traffic flows in the amended PSDF scheme.

59. The tables highlight that when compared to the ES assessment, the PSDF as
amended, will result in reduced traffic flows on specific links, including the A412
Church Road / Denham Road, Pinewood Green and Pinewood Road, however it
will result in an increase in traffic on Sevenhills Road. Notwithstanding this, there
will be no change to the overall predicted impacts across the study area when
compared to those concluded within the ES.
60. The PSDF as amended assessment (assessment of impacts against future year
baseline) is set out in full below.
Construction Assessment
61. The proposed secondary controlled vehicular access from Sevenhills Road would
not be provided for construction vehicle use; therefore the approach set out within
the ES does not change.
62. It is noted however that there will be a small amount of further additional
construction traffic associated with the construction of the secondary controlled

vehicular access and Sevenhills Road/Denham Road signalised junction
improvement scheme.
63. The construction assessment takes account of the impacts associated with the
construction of the secondary controlled vehicular access. The works envisaged to
allow delivery of the access will comprise upgrading the Sevenhills Road
emergency access by undertaking the following amendments:
• grasscrete surfacing to be upgraded to tarmac surfacing;
• position of proposed gate (relating to its use as an emergency access) set back
into the site by 10m and replaced by a swipe card operated access control
barrier.
64. The secondary controlled vehicular access construction works set out above are
small in scale, and would take place across a short duration of up to four weeks.
As such, the works would generate a minimal number of vehicle movements
which would not be discernible from background traffic.
65. As noted earlier in this SES, the provision of a secondary controlled vehicular
access is reliant on the prior delivery of the Sevenhills Road/Denham Road
signalised junction improvement scheme. This construction of this junction
improvement scheme is therefore included within the assessment.
66. The junction improvement scheme will alter the existing highway layout to
incorporate revised kerb lines, traffic islands and traffic signals equipment. It is
envisaged that the works would take place over several weeks, however the
number of construction traffic vehicles generated will be very low (mainly
deliveries of materials, etc.). The works will comprise traffic management to
ensure that delay to drivers on the A412 or Sevenhills Road is mitigated.
67. The impact of construction traffic from the amended PSDF scheme will therefore
be negligible due to the very small increase in flows. In light of the above, the
results of the ES Construction Traffic Assessment remain unchanged.
Operational Assessment
68. The operational assessment has been undertaken for 2033 when it is predicted that
PSDF will be fully operational.
69. This SES assessment includes the following transport measures that form part of
the proposals for the Project:
• New site access from Pinewood Road;
• New secondary controlled vehicular access from Sevenhills Road. The
secondary access will be available for use by emergency vehicles at any time
and employees between 07:00 and 19:00;
• Improvements to FPR; and
• Combined footpath/cyclepath on Pinewood Road.
70. However, it is important to note that the assessment assumes the same modal split
as currently occurs at the site. Therefore it assumes no reduction in the proportion
of staff, contractors and visitors who travel to the site by car as a result of the

sustainable transport strategy outlined earlier in this SES. This is therefore a very
robust assessment.
71. Full details of the derivation of the traffic generation and distribution estimates are
provided in the STA. The STA considers the assignment of employee traffic with
a secondary controlled vehicular access provided from Sevenhills Road.
72. Information is presented for all vehicles, HDVs only and for daily and peak hour
traffic flows in Tables 4 - 9.

73. As can be seen, over a 24 hour period, the greatest numerical increase in total
traffic volumes can be seen on Pinewood Road, Wood Lane, Denham Road and
Sevenhills Road. The largest change in traffic flows in percentage terms can be
seen on Sevenhills Road, Pinewood Road and Fulmer Common Road.
74. The increase on Sevenhills Road is due to the great majority of the amended
PSDF operational traffic to/from the site that comes from the north east i.e. from
the A40/A412 Denham Roundabout being assumed to use the Sevenhills Road
access. However, as will be considered below that actual flows on Sevenhills
Road are low.
75. Turning to HDVs it should be remembered that this is a wide definition of
vehicles including any vehicles with a weight greater than 3.5 tonnes which
includes, for example, some transit vans. Based on an analysis of traffic
accessing/eggressing Pinewood Studios, if only HGVs were assessed the flows
would be some 35% less. It should be noted that the assignment and impact of
HDVs is not changed from the original ES as a result of this SES. This is because
the secondary controlled vehicular access on Sevenhills Road will not be used for
construction access.

traffic volumes can be seen on Pinewood Road, Wood Lane, Sevenhills Road and
Denham Road. The most significant change in traffic flows in percentage terms
can be seen on Pinewood Road, Sevenhills Road and Fulmer Common Road. The
reason for the change on Sevenhills Road is as set out for daily flows.
77. In relation to HDVs, as previously noted care is required when considering
percentage changes. For example whilst there is a 100% increase in Fulmer
Common, this is only an increase of 4 vehicles per hour or one every 15 minutes.

on Pinewood Road, Sevenhills Road and Fulmer Common Road. The reason for
the change in flows on Sevenhills Road is as set out for daily flows.
Severance
79. Examining daily flows, there are no increases greater than 30% except on
Pinewood Road and Sevenhills Road. Therefore on this criterion, on all links
other than stated above, the impacts of the amended PSDF scheme are expected to
be negligible.
80. The increase on Pinewood Road (south of the Site Access), which is judged to be
a receptor of minor sensitivity, is predicted to be approximately 54.1%. This is
considered to be a minor adverse magnitude of impact and this will result in a
negligible significance of impact.
81. The increase in vehicle traffic flows on Sevenhills Road is predicted to be
approximately 93.8%. However, the existing volume of traffic on the road is very
low and the increase of 1,260 vehicles per day (an average of 90 movements per
hour) is considered modest. Importantly no additional HDVs will be attracted
along the road.
82. Sevenhills Road is a road with a mix of residential and commercial properties
generally set back from the road. There are no community uses on the road (eg
schools, restaurants etc.) and no reason why pedestrians would wish to cross the
road. Observations have shown there to be negligible pedestrian activity on the
road.
83. Therefore whilst a strict interpretation of the IEMA Guidelines would lead to a
substantial magnitude of impact on a moderate sensitivity receptor it is considered
that in reality the impacts are likely to be more moderate and the significance of
the impact of the amended PSDF scheme is assessed to be moderate adverse.
84. In terms of HDVs, the majority of links experience a negligible increase in traffic
i.e. less than 30% change in HDVs.
85. The links that experience an increase in HDV daily flows of between 30% and
60% (i.e. a minor magnitude of impact) are shown below:
• Pinewood Road;
• Fulmer Common Road
86. These links are judged to be receptors of minor sensitivity and therefore the
significance of the impact of the amended PSDF scheme is negligible.
87. Taking into account the above range of impacts on different links, in overall terms
across the whole network, the significance of the severance impact is assessed to
be minor adverse.
Pedestrian Delay
88. The analysis shows that there are only seven links which have an hourly flow
greater than 1,400 vehicles. The seven links are as follows:
• A40 Oxford Road (between Denham Roundabout and Southlands Road)

• A412 Uxbridge Road (just West of Billet Lane)
89. In the AM peak, none of the links experience an increase in traffic flow as a result
of the amended PSDF scheme of more than 10%, except Wood Lane which
experiences an increase of 12%. In the PM peak all the increases are less than
10% with the greatest increase being 6.8% on Wood Lane. Therefore all of the
magnitude of impacts are considered negligible. None of these receptors are of
substantial sensitivity and therefore the significance of the impacts is negligible.
90. It should also be noted that the improvements to FPR, will improve crossing times
for pedestrians wishing to cross at this point. This is discussed further in the FPR
section below.
Pedestrian Amenity
91. Based on advice in the IEMA Guidelines, the change in flows at which pedestrian
amenity changes should be considered in detail are a doubling or halving in the
flow of all traffic or HGVs.
92. Across a day and during the peak hours none of the total traffic flows on any link
halve or double. HDV flows do increase by 100% or more during peak periods on
Pinewood Road and on Fulmer Common Road. However, these are very low
numerical increases – between 4 and 12 movements an hour which is a negligible
increase. As a result, in overall terms the amended PSDF scheme will have a
negligible magnitude of impact on pedestrian amenity within the study network.
Furthermore, the improvements to FPR and the provision of the combined
footway/cycleway on Pinewood Road will enhance the amenities for pedestrians.
93. All receptors are of less than substantial sensitivity except Pinewood Green and
the A4007 (west of Swallowdale) and therefore the significance of impact on all
links except those two, is negligible. The impact of daily flows and HDV flows
on these links is less than 10%, therefore the significance of the impact of the
amended PSDF scheme is negligible.
Accidents and Safety
94. An assessment of accident data has been undertaken to evaluate the likely
fluctuations in accidents at the key junctions and links within the study area in the
ES.
95. The ES stated that traffic generated by the PSDF will have a negligible effect on
accidents and safety. In addition the improvements at Five Points roundabout
would result in a beneficial effect in relation to accidents and safety at this
location. In summary, it concluded that the significance of impact in relation to
accidents and safety is assessed to be minor beneficial.

96. The assessment of the amended PSDF scheme will lead to an increase in traffic
flows on Sevenhills Road. However, the total volume of traffic is modest and
there is no adverse accident record on Sevenhills Road. Therefore the effect is
considered negligible. The introduction of the Sevenhills Road/Denham Road
junction improvement will lead to a minor beneficial effect on safety.
Cumulative and Interactive Effects
97. As noted in the methodology section, the assessment provided above includes
traffic growth to take account of potential developments in the area and also
includes for the provision of the Sevenhills Road/Denham Road junction
improvements.
98. Furthermore, as the junction improvement to Five Points Roundabout has been
granted planning permission (Ref 13/00176/FUL). This junction improvement
scheme is also included within the assessment.
99. As the assessment includes traffic growth and local highway improvements it is,
in effect, a cumulative assessment.
5.9 Mitigation Measures
Construction
100. The proposed secondary controlled vehicular access onto Sevenhills Road would
not be provided for construction vehicle use, therefore the results of the ES
Construction Traffic Assessment remain unchanged.
Operation
101. The assessment carried out in this section of the SES assumes the implementation
of the core access works and highway improvements as described earlier. No
impacts of substantial significance were assessed and only in Sevenhills Road was
an impact of moderate adverse significance assessed.
102. Notwithstanding the above, there are additional transport measures that PSL
propose to introduce that will further mitigate the impacts of the scheme.
103. These measures are contained within the Sustainable Transport Strategy which is
described in full within the TA and as set out within the proposed S106
agreement.
5.10 Residual Effects
Construction
104. The proposed secondary controlled vehicular access from Sevenhills Road would
not be provided for construction vehicle use, therefore the results of the ES
Construction Traffic Assessment remain unchanged.

Operational
105. It should be noted that the above results do not consider a quantitative analysis of
the impact of the Travel Plan which has been estimated to result in a 20%
reduction in single-occupancy vehicle trips associated with amended PSDF
scheme over a 20 year period. Nor do they take account of the contribution that
will be made to pedestrian and cycle improvements in the area. Whilst a
quantitative analysis has not been undertaken, these measures will further mitigate
any adverse impacts.
106. On Sevenhills Road, it is considered there is significant opportunity for traffic
flows (which are exclusively employes) to reduce as a result of the Travel Plan
measures. Furthermore the S106 Obligation includes for a Additional Transport
Fund to mitigate any impacts that arise as a result of the development if deemed
appropriate by the Transport Review Group. Such funding could be used to
provide traffic management measures on Sevenhills Road if they were deemed to
become necessary.
107. In the light of the above, we consider that the assessment of the significance of the
impact of Severance on Sevenhills Road in the amended PSDF scheme is reduced
from moderate to minor.
5.11 Offsetting and Enhancement
108. There are no offsetting measures proposed by PSL. All relevant transport
measures are included as the core scheme or as mitigation. However, it should be
noted that a number of the transport measures do lead to enhancements in the area
for the wider community. For example, the improvement to FPR and the walking
and cycling improvements.

6 Air Quality
6.1 Introduction
110. This section supplements the relevant parts of the ES Air Quality chapter that
have changed as a result of the PSDF scheme amendments. It provides an
assessment of the potential air quality effects associated with the provision of a
secondary controlled vehicular access via Sevenhills Road, and for clarification,
includes a comparison of the impacts associated with the PSDF scheme without
the secondary controlled vehicular access (as set out within the ES).
6.2 Relevant elements of the proposed development
111. The proposed amendments described in Section 3 are relevant to the assessment
given that they will alter traffic flows and consequently have the potential to alter
the dispersion of exhaust emissions from construction and operational traffic.
6.3 Scoping and Consultation
112. No further scoping or consultation with respect to air quality assessment has been
undertaken since the submission of the original ES.
6.4 Methodology
Introduction
113. The methodology for the air quality assessment remains unchanged from the
approach as reported in the original ES.
Policy Context
114. The policy context remains unchanged from that reported in the ES.
Baseline methodology
115. The baseline methodology remains unchanged from that reported in the ES.
Construction assessment methodology
116. The construction methodology remains unchanged from that reported in the ES.
Assessment methodology for operational effects
117. In order to assess the impacts of the use of the secondary controlled vehicular
access on local air quality, a new set of traffic data was provided (see Appendix
D) and the air quality model was re-run. The setup of the model, its input
parameters, options and meteorological data were the same as in the ES
assessment to ensure consistency and comparability of the results with the original
assessment.

Assessment scenarios
118. Pollutant concentrations have been calculated for the future assessment year 2033
for three scenarios. These assessment scenarios are summarised as follows:
• ‘Do-Minimum scenario’: the future year 2033 without PSDF (including
committed developments);
• ‘ES scenario’: the future year 2033 with PSDF (including committed
developments and Five Points Roundabout) as was assessed in the ES and
without the use of the secondary access; and
• ‘SES scenario’: the future year 2033 with the amended PSDF scheme
incorporating the secondary controlled vehicular access (including committed
developments and Five Points Roundabout).
119. The ‘Do-Minimum scenario’ provides the base for the future assessment year and
is the same scenario assessed in the ES. The ‘ES scenario’ refers to the traffic
scenario associated with the operation of the PSDF without the use of a secondary
controlled vehicular access. This scenario corresponds to the scenario assessed in
the ES. The ‘SES scenario’ refers to the traffic scenario associated with the
operation of the PSDF as amended using the secondary controlled vehicular
access onto Sevenhills Road.
Receptors
120. The same human receptors as those assessed in the ES were used in this SES. It is
expected that changes in traffic flows due to the use of the secondary controlled
vehicular access are not likely to affect the conclusions of the ecological receptors
assessment given the very small changes in predicted concentrations, thus the
conclusions in the ES are considered to remain valid.
Traffic data and assumptions
121. Traffic data was provided for the same road network as that assessed in the ES.
The main changes in traffic flows due to the use of the secondary controlled
vehicular access are observed on Sevenhills Road, Church Road and Pinewood
Road. The data provided by Vectos included 24h Annual Average Daily Traffic
(AADT) two-way flows, the percentage of those flows comprising Heavy Duty
Vehicles (HDVs) and average speeds.
122. Emission rates were calculated using the UK EFT2012 v5.1.3 2 emissions dataset
for consistency with the ES. Table 11 presents the traffic data for the assessment
scenarios (data in bold show the changes in traffic flows due to the use of the
secondary controlled vehicular access).

Background pollutant concentrations
123. The model predicts the contribution from the roads and other explicitly modelled
sources (eg. car parks). Background concentrations are then added into the model
to derive total pollutant concentrations suitable for comparison with the air quality
standards. The same background concentrations for 2033 derived from the Defra
background maps were used in this study for consistency with the ES assessment.
6.5 Assumptions and Limitations
124. The assumptions and limitations of this assessment are set out within the ES. In
addition to those set out in the ES, in assessing the impacts of the secondary
access, this assessment assumes the advance implementation of the Sevenhills
Road/Denham Road signalised junction improvement scheme.
6.6 Baseline
125. The baseline conditions remain unchanged from those identified within the ES.
6.7 Assessment
Construction: nuisance dust assessment
PSDF
126. The small increase in traffic associated with construction of Sevenhills Road as
secondary controlled vehicular access will have negligible impact in terms of dust
generation. The significance of effect overall will remain as was reported for the
ES.
Five Points Roundabout
127. The significance of effect with respect to construction effects at FPR remains as
was reported in the ES.
Combined effects
128. The combined effect of construction traffic on both PSDF and FPR will remain as
reported for FPR.
Construction traffic assessment
129. The small increase in additional construction vehicles to upgrade Sevenhills Road
to secondary permanent access will not result in a change to the conclusions of the
ES. The change in concentrations of N02 PM10 will remain imperceptible and the
significance overall remains negligible.

Modelled pollutant concentrations
130. Total pollutant concentrations for NO2 and PM10 are presented in Table 12 at
each of the assessed receptors. It can be observed that modelled concentrations are
well below the air quality standards at all receptors and only imperceptible
changes (less than 0.4μg/m3) are predicted.
131. The maximum increase in NO2 concentrations is predicted at receptor R24 (South
Lodge) on Pinewood Road, while the maximum decrease at receptor R04 (Oxford
Road 2) on Oxford Road due to the implementation of the proposed development.
132. Considering the change between the ‘SES scenario’ and the ‘ES scenario’,
differences in concentrations only occur at the receptors closest to the roads with
re-routed traffic. Table 13 shows the changes in concentrations at these receptors
split by roads. It can be observed that all changes in concentrations are
imperceptible, with increases at the receptors on Sevenhills Road and decrease at
all other receptors, which is expected from the traffic changes due to the use of the
secondary controlled vehicular access.

Assessment of significance
133. Following the EPUK guidance, the following can be noted:
• The magnitude of change is imperceptible at all assessed receptors for both
annual mean NO2 and PM10 concentrations both with and without the use of
the secondary controlled vehicular access during operation of the PSDF
development.
• The modelling results show that the air quality standards are predicted to be
met at all receptors for NO2 and PM10 both with and without the use of the
secondary controlled vehicular access during operation of the PSDF
development.
134. Taking the above into consideration, the operation of the amended PSDF scheme
on local air quality with the use of the secondary controlled vehicular access can
be described as insignificant.
FPR
135. The conclusions of the ES remain unchanged with respect to FPR.
Combined effects
136. As the air quality assessment already includes the effect of the PSDF and FPR
schemes and therefore the conclusions remain as above.

7 Noise and Vibration
7.1 Introduction
147. This section supplements the relevant parts of the ES noise and vibration chapter
that have changed as a result of the PSDF scheme amendments. It provides an
assessment of the potential noise and vibration effects associated with the
provision of a secondary controlled vehicular access via Sevenhills Road, and for
clarification, includes a comparison of the impacts associated with the PSDF
scheme without the secondary controlled vehicular access (as set out within the
ES).
7.2 Relevant Elements of the Proposed Development
148. The proposed amendments described in Section 3 are relevant to the assessment
given that they will alter traffic flows and consequently have the potential to alter
vehicle noise emissions from construction and operational traffic.
7.3 Scoping and Consultation
149. No further scoping or consultation with respect to noise and vibration has been
undertaken since the submission of the original ES.
7.4 Methodology
Introduction
150. The methodology for the noise assessment remains unchanged from the approach
taken for the original ES.
Policy Context
151. The policy context remains unchanged from that reported in the ES.
Baseline methodology
152. The baseline methodology remains unchanged from that reported in the ES.
Construction assessment methodology
153. The methodology for the assessment of construction effects with respect to noise
and vibration remains unchanged from that reported in the ES.
Assessment methodology for operational effects
154. The methodology of assessment of operational effects from noise and vibration
remains unchanged from the ES. The revised noise assessment reports the changes
to the predicted operational road traffic noise arising from the proposed Sevenhills
Road secondary access. The calculations have been undertaken using traffic flow
data supplied by Vectos in July 2013. This data is supplied as Appendix B.

Supplementary Environmental Statement
155. Calculations have been undertaken for scenarios with and without the secondary
controlled vehicular access for the same road links as those assessed in the ES.
7.5 Assumptions and Limitations
156. The assumptions and limitations of this assessment are set out within the ES. In
addition, in assessing the impacts of the secondary access, this assessment
assumes the advance implementation of the Sevenhills Road/Denham Road
signalised junction improvement scheme.
7.6 Baseline
157. The baseline noise environment remains unchanged from that reported in the ES.
7.7 Assessment
Construction
Noise: PSDF Site
158. The likely small numbers of additional construction plant and vehicles associated
with the conversion of Sevenhills Road to a secondary vehicular controlled access
are not expected to lead to significant change to the predicted construction traffic
noise. As such, the conclusions of the ES with respect to affected receptors around
the PSDF site remain unchanged.
Noise: FPR Site
159. The small increase in construction traffic associated with the secondary vehicular
controlled access on Sevenhills Road is not expected to lead to a significant
increase in traffic noise around the FPR site. As such, the conclusions of the ES
with respect to affected receptors around the FPR site remain unchanged.
Vibration: PSDF Site
160. The assessment of vibration effects at the PSDF site remains unchanged from that
reported in the ES.
Vibration: FPR Site
161. The assessment of vibration effects at the FPR site remains unchanged from that
reported in the ES.

Operational
Noise from Building Services Plant
162. There are no required changes to building services plant as a result of the
proposed changes so the conclusions of the ES with respect to plant noise are
unchanged.
Noise from traffic within the Proposed Development
163. There are no changes to the conclusions of the ES with respect to traffic within
the Proposed Development.
Noise from traffic on surrounding roads
164. Table 15 summarises the changes due to the operation of the Sevenhills Road
secondary access:
• in absolute terms; and
• in terms of the difference compared with the original predictions in the ES.
165. The largest increase due to the additional staff access (shaded red in Table 15) is
on Sevenhills Road. In absolute terms, the increase is less than 3dB. As set out in
Table 12.5 of ES Volume 1, a noise change of +3dB or greater is an indicator of a
potentially significant effect. Therefore the results indicate that PSDF scheme
amendments incorporating a secondary controlled vehicular access onto
Sevenhills Road would lead to a not significant effect.
166. The relative change between the predicted noise levels cited in the ES and the new
assessment further demonstrates that the noise from traffic as a result of the
additional access does not lead to a significant change in the results of the traffic
noise assessment contained in the ES.
167. The amended PSDF scheme incorporating use of the secondary controlled
vehicular access onto Sevenhills Road results in the reduction of traffic flows on
other nearby roads, leading to a small reduction in traffic noise from those roads
(shaded green in Table 15), and particularly on Pinewood Green.

8 Ecology and Nature Conservation
8.1 Introduction
182. This section supplements the relevant parts of the ES Ecology chapter that have
changed as a result of the PSDF scheme amendments. It provides an assessment
of the potential effects on ecology associated with the provision of a secondary
controlled vehicular access via Sevenhills Road,
8.2 Relevant elements of the proposed development
183. The proposed amendments described in Section 3 are relevant to the assessment
given that they will alter traffic flows along Sevenhills Road and consequently
have the potential to cause disturbance to wildlife from construction and
operational traffic.
184. There are no other changes to the reporting of this section in the ES (Section 8.2).
8.3 Scoping and Consultation
185. Consultation has been undertaken with BCC with respect of other ecological
issues associated with the proposed development. This has been addressed

186. There has been no consultation regarding ecological assessment of the proposed
amendment reported in this SES.
8.4 Methodology
187. There is no change to the approach to the methodology of ecological assessment
during construction or operation as set out in the ES.
8.5 Assumptions and Limitations
188. There is no change to the assumptions and limitations of assessment as reported in
the ES.
8.6 Baseline
189. There is no change to the ecological assessment findings with respect to the
baseline condition.
8.7 Impact Assessment
Construction
190. The effect of small numbers of additional construction vehicles to upgrade the
Sevenhills Road access to a secondary controlled vehicular access is considered to
be insignificant. The conclusions of the ES with respect to construction effects
therefore remain unchanged.

Operation
PSDF East and West Area
191. The amended PSDF scheme will not result in any loss of habitat of value, and no
change to the assessment previously reported is predicted with respect to habitats.
However the operation of the secondary controlled vehicular access onto
Sevenhills Road will have implications for disturbance to bats and an obstacle for
the movement of reptile species in this part of the site.
192. The amended scheme would result in an estimated additional 1,260 vehicle
movements per day using the secondary controlled vehicular access onto
Sevenhills Road. The vehicle movements are expected to result in additional noise
and light pollution from car headlights. This has the potential to result in
disturbance to the bat roost at Saul’s Farm or deter the use of the roost, and to
deter reptiles from crossing the access road and dispersing widely across the site.
Bats at Saul’s Farm
193. There is currently a large brown long-eared bat maternity roost at the main farm
house at Saul’s Farm, which is considered to be of value in a county context. The
house lies within approximately 6 metres of the proposed secondary controlled
vehicular access and is separated from it by a tall hedge. The disturbance from
noise and lighting glare from vehicle headlights is likely to deter bats from
emerging and/or re-entering the roost between the months of April to September.
However, the operation of Sevenhills Road as secondary controlled vehicular
access will be restricted to the times of 07:00 to 19:00 all year round and these
times are outside the peak periods of bat activity associated with emergence and
re-entry to the maternity roost. With such measures in place the significance of
effect is considered to be negligible.
Reptile movements
194. Small populations of reptiles occur principally around and within the Clump and
along some of the radiating hedgerows. In order to maintain suitable habitats on
site, mitigation measures have been embedded into the PSDF design including
habitat creation and maintaining appropriate links. The embedded measures
included a link suitable for reptiles across the main access road off Pinewood
Road and the grasscrete surface of the emergency-only access onto Sevenhills
Road.
195. The objective of the links is to provide intermittent dispersal routes for reptile
species, allowing the populations to mix. In the absence of the links there is a risk
of a decline in the population, as it would be less resilient to change. The link
provided under the main access off Pinewood Road provides a link to all of the
main areas of the site and will facilitate the potential movement of reptiles
between them. Therefore the potential disturbance caused by additional vehicles,
and change in substrate of the secondary controlled vehicular access onto
Sevenhills Road is predicted to result non-significant effect. The conclusions of
the ES in this regard therefore remain unchanged.
Five Points Roundabout
196. There is no change to the ecological assessment findings with respect to
ecological effects at Five Points Roundabout.

Bats at Saul’s Farm
200. The hedgerow between the identified bat roost and Sevenhills Road secondary
controlled vehicular access will be managed to retain height, to encourage bats to
fly above the height of the vehicles. No other measures beyond the proposed
restricted times of operation of Sevenhills Road as secondary controlled vehicular
access are considered to be required.
Reptiles
No mitigation measures other than those reported in the ES are considered
necessary.
Five Points Roundabout
201. There is no change to the recommendations in the ES with respect to ecological
mitigation measures for the operation of Five Points Roundabout.

204. With the hedgerow mitigation in place, the secondary controlled vehicular access
onto Sevenhills Road will not give rise to significant impacts upon the brown
long-eared bat maternity roost at the main farm house at Saul's Farm.
205. The residual effects of operation are otherwise unchanged as reported in the ES.
