15. LANDSCAPE AND VISUAL AMENITY
15.1 Introduction
This chapter of the Preliminary Environment Information Report (PEIR) presents
the preliminary results of the assessment of likely significant effects of the
Heathrow Expansion Project (the DCO Project) with respect to landscape and
visual amenity.
‘Landscape’ is defined in the European Landscape Convention, Council of Europe
(2000), as:
“...an area, as perceived by people, whose character is the result of the action and
interaction of natural and / or human factors.”
Landscape character arises from the pattern of these factors, or elements (such as
woodland cover and watercourses), that make one landscape different from
another and includes perceptual aspects such as tranquillity. In urban areas
landscape may be termed townscape, which includes buildings and urban open
space; where relevant, landscape is therefore referred to as townscape. Visual
amenity considerations relate specifically to the composition and quality of views
afforded to people. Landscape and visual amenity issues are related but
considered separately as part of Landscape and Visual Impact Assessment
(LVIA).
There are also some areas in which the assessment of landscape and visual
amenity effects will be informed by the assessments undertaken in relation to
other topics. This chapter should be read in conjunction with the project
description provided in Chapter 6: DCO Project description and the relevant
parts of the following chapters:
Chapter 8: Biodiversity - effects in relation to habitats and nature
conservation sites, which may also contribute to landscape and visual amenity
(nature conservation sites may also be designated as areas such as Country
Parks and Open Access Land, affording public amenity as well as performing
nature conservation functions)
Chapter 11: Community - effects in relation to people, homes and community
facilities / public services, public open space and routes (including those for
recreation), which may form visual amenity receptors (those who may have a
view of the DCO Project)
Chapter 13: Historic environment - effects regarding historic landscape
character together with historic environment features and their setting, which
inform landscape character and visual amenity

15.2 Relevant legislation, policy and other important and relevant matters
Introduction
This section identifies the legislation, policy and other documentation that has
informed the assessment of effects presented in relation to landscape and visual
amenity. Further information on policies relevant to the EIA and their status is
provided in Chapter 2: Legislative and policy overview of this PEIR.
Legislation and national planning policy
Table 15.1 lists the legislation relevant to the assessment of effects on landscape
and visual amenity receptors.
Table 15.1: Legislation relevant to landscape and visual amenity
Legislation description Relevance to assessment European Landscape Convention (ELC) (Council of Europe, 2000) The European Landscape Convention (ELC) was
signed by the UK Government in February 2006,
ratified in November 2006 and came into effect in
March 2007. The ELC is a European Treaty
which encourages the integration of landscape
considerations into all relevant areas of policy.
Valued landscapes and landscape character are
considered as part of the landscape and visual amenity
assessment within this chapter. The assessment relating
to these matters is set out in Section 15.10.
National Parks and Access to the Countryside Act 1949, as amended National Parks and Areas of Outstanding Natural
Beauty (AONB), which are nationally designated
landscapes, are designated under the provisions
of the National Parks and Access to the
Countryside Act (1949).
The nationally designated Chiltern Hills AONB lies outside
of the Draft DCO limits, over 10km from the DCO Project.
However, the tranquillity aspect of the Chiltern Hills AONB
landscape has the potential to be affected by new aircraft
movements associated with the DCO Project, which is
considered within this chapter based on available
information. The assessment relating to these matters is
set out in Section 15.10. Countryside and Rights of Way Act 2000, as amended Section 85 of the Countryside and Rights of Way
Act (2000) provides that in exercising or
performing any functions in relation to, or so as to

landscape has the potential to be affected by new aircraft
movements associated with the DCO Project, which is
considered within this chapter based on available
information. The assessment relating to these matters is
set out in Section 15.10.
Table 15.2 lists the national planning policy relevant to the assessment of effects
on landscape and visual amenity receptors.
Table 15.2: National planning policy relevant to landscape and visual amenity
Policy description Relevance to assessment
Airports National Policy Statement (ANPS) (Department for Transport, 2018): Chapter 2: Legislative and policy overview
provides an explanation of the relevance of the
ANPS to the DCO Project in general terms. The
ANPS is the primary basis for decision making on the
DCO Project.
The Airports National Policy Statement (ANPS)
includes a dedicated section on landscape and visual
impacts, as set out within paragraphs 5.213 to 5.225.
As is consistent with the ANPS, this chapter includes
the following:
Reference to landscape character assessment studies
and local development documents to inform the
preliminary assessment, as set out in Section 15.2, Section 15.6, Section 15.9 and Appendix 15.1: Local landscape and townscape character, Volume 3.
A preliminary assessment of any likely significant
landscape and visual effects during construction and
operation, including effects arising from Surface
Access Proposals or aviation activity, as set out in
Section 15.10.
A preliminary assessment of the visibility of the DCO
Project (this is aided by modelling of a preliminary
Zone of Theoretical Visibility) and potential effects on
views and visual amenity (including as a result of the
conspicuousness of the DCO Project), as out in
Section 15.9 and Section 15.10.
A preliminary assessment of light pollution effects (this
is considered in relation to night-time visual amenity),
as set out in Section 15.10.
A preliminary assessment of tranquillity (this is
considered in relation to landscapes/townscapes,
including nationally designated landscapes), as set out
in Section 15.10, with consideration of noise (this is
considered through cross-reference to Chapter 17, as
set out in Section 15.1and noting that whilst visual
effects are reported separately from

landscape/townscape effects (as set out in Section 15.1) they have a bearing on tranquillity and are
therefore considered in the broader perceptual
analysis of tranquillity relating to landscapes and
townscapes.
As set out in Section 15.1, this chapter should be read
in conjunction with the relevant parts of Chapter 8, as
habitats and nature conservation sites may contribute
to landscape and visual amenity. References to such
sites are made within Section 15.9 and supporting
Appendix 15.1.
The nationally designated Chiltern Hills AONB lies
outside of the draft DCO limits, over 10km from the
DCO Project. However, the tranquillity aspect of the
Chiltern Hills AONB landscape has the potential to be
affected by new aircraft movements associated with
the DCO Project, which are considered within this
chapter, based on available information.
Consideration of proposed built environment elements
and green infrastructure, as components of carefully
considered design, to minimise negative landscape
and visual effects, as set out in Section 15.5 and
Section 15.10. National Policy Statement for National Networks, (NN NPS) (Department for Transport, 2014): The NN NPS includes a dedicated section on
landscape and visual impacts, as set out within
paragraphs 5.143 to 5.161.
The NN NPS is consistent with the ANPS direction in
respect of landscape and visual effects; this chapter
includes the assessment described in the row above
(for the ANPS) for the DCO Project, including those
parts of the DCO Project which constitute
improvements to national networks which would qualify
as NSIPs and would need to have regard to this NPS.
National Planning Policy Framework, (NPPF) (Ministry of Housing, Communities and Local Government, 2019): Paragraph 127 of the NPPF states that
developments should be “visually attractive” and
“sympathetic to local character and history, including
the surrounding built environment and landscape
setting, while not preventing or discouraging
appropriate innovation or change.”
Paragraph 141 of the NPPF directs local planning
authorities to “retain and enhance landscapes [and]
visual amenity” within the Green Belt.
Paragraph 170 of the NPPF states that planning
This chapter considers effects in relation to valued
landscapes (including nationally designated
landscapes, such as AONBs, and locally valued
landscapes, such as those within the Green Belt and
Metropolitan Open Land), local character (landscape
character areas and townscape character types/areas)
and visual amenity as set out principally in Section 15.6, Section 15.9 and Section 15.10.

decisions “should contribute to and enhance the
natural and local environment by: protecting and
enhancing valued landscapes…[and] recognising the
intrinsic character and beauty of the countryside…”
Paragraph 172 states that “great weight should be
given to conserving and enhancing landscape and
scenic beauty in National Parks, the Broads and
AONBs, which have the highest status of protection
in relation to these issues.”
Regional and local planning policy
Appendix 2.1: Regional and local planning policy and other important and relevant matters, Volume 3 presents the full list of the regional and local planning
policies and other documentation relevant to the assessment of the effects on
landscape and visual amenity receptors.
Local planning policies from the following host and neighbouring local authorities
have been considered; these have been considered because they fall within the
landscape and visual amenity study area:

assessment is provided within Appendix 2.1.
15.3 Scoping and engagement
Overview
This section describes the outcome of, and response to, the Scoping Opinion in
relation to landscape and visual amenity and also provides details of the ongoing
technical engagement that has been undertaken with stakeholders and individuals.
An overview of engagement undertaken can be found in Section 1.5 of Chapter 1: Introduction.
Engagement has taken the form of ongoing discussions, formal meetings and
document sharing and is summarised in the following sections.
Scoping Opinion
A Scoping Report requesting a Scoping Opinion was submitted to the Secretary of
State, administered by the Planning Inspectorate (PINS) on behalf of the Secretary
of State, on 21 May 2018. The Scoping Report set out the proposed aspect
assessment methodologies, outlined the baseline data collected to date and
proposed for the ES and set out the scope of the assessment.
A Scoping Opinion was adopted by PINS, on behalf of the Secretary of State, on
2 July 2018 and is provided in Appendix 1.2: Scoping Opinion, Volume 3. Table 15.3 sets out the comments received in section 4 of the Scoping Opinion ('Aspect
based scoping tables') for landscape and visual amenity (Table 4.10 in the
Scoping Opinion). The information provided in the PEIR is preliminary and
therefore not all the Scoping Opinion comments have been able to be addressed
at this stage. Scoping Opinion comments that have not been addressed in the
PEIR will be addressed within the ES. Table 15.3 therefore describes, where
possible, how the Scoping Opinion responses have been addressed in this PEIR.
Comments from other consultation bodies received are provided in Appendix 2 of
the Scoping Opinion.

any relevant cumulative effects. The
justification for this is based on the fact
that the Proposed Development does not
lie within a marine or coastal location. The
Inspectorate is satisfied that having regard
to the location of the Proposed
Development significant effects to
seascape are unlikely to occur and this
matter can be scoped out.
101 The Scoping Report sets out the intention
to conduct an assessment of impacts to
tranquillity (as it relates to character of the
landscape) and makes reference to
Campaign to Save Rural England’s
Tranquillity Mapping in this regard. In
addition to acknowledging tranquillity as a
key factor in landscape character area
sensitivity assessments the ES should
also include consideration of significant
effects on tranquillity from overflying
aircraft. The Applicant should also ensure
that an assessment of impacts to
tranquillity relevant to other aspects is
assessed in the relevant ES chapters.
The approach to assessing the effects
of overflying aircraft on tranquillity, as it
relates to landscape and visual
amenity, has been agreed with Natural
England (as set out in paragraph
15.3.11, below). The approach is
provided in Section 15.4 and Section 15.6. Following discussion with PINS
the following aspects also include
consideration of tranquillity within their
assessments –
Chapter 11 Chapter 12 Chapter 13 Chapter 17.
102 The Scoping Report explains that
engagement with the HSPG on agreeing
the approach to the assessment and
mitigation of landscape and visual impacts
of the Proposed Development. The
Inspectorate recommends that similar
effort is made to consult with any
surrounding local authorities and other
relevant organisations that may be
affected by the Proposed Development
but not represented in the HSPG e.g.
Chilterns AONB Conservation Board.
Effort has been made to engage with
all surrounding local authorities. The
outcomes of engagement to date are
set out under the heading Technical
engagement in Section 15.3. Local
authorities who are not represented in
HSPG and that have been contacted
in order that they may be consulted,
include the London Borough of
Hillingdon and the London Borough of
Richmond upon Thames. However,
their current position has been not to
take up this offer. Further engagement
will take place following issue of the
PEIR and prior to issue of the ES,
including with the Chilterns AONB
Conservation Board.
103 The Scoping Report states that the study
area extends to a 5km radius from the
maximum amount of land being
considered for the full range of options for
the Proposed Development, but that this
The updated study area and Zone of
Theoretical Visibility (ZTV) are
included within the PEIR on Figure 15.1, Volume 2. The outcomes of

may continue to evolve to accommodate
any changes as the design process
progresses. The ES should clearly
evidence and justify the final extent of the
study area used in the assessment of
landscape and visual impacts, having

The study area should contain all likely
significant effects of the Proposed
Development on any component of

should be made to agree this with relevant
consultation bodies, where possible.
the heading Technical engagement in
Section 15.3.
104 The Scoping Report states that baseline
data collection is on- going, with both desk
studies and field surveys undertaken to
date. The ES should clearly set out all
studies and surveys undertaken to inform
the final baseline information, including
the timing of any site visit and how/if
professional judgement has been applied.
The Applicant should make effort to agree
its approach with the relevant consultation
bodies.
The updated baseline information
(including desktop studies and
surveys) is included within the PEIR in
Section 15.9. The outcomes of
engagement to date, including that
regarding the approach to gathering
baseline information, are set out in
Section 15.3.
105 The Scoping Report states that a
preliminary ZTV for operational
infrastructure and development
components has been mapped based on
indicative height parameters for the
various components of the Proposed
Development, and that this will be
updated as the DCO process progresses.
The ES should clearly evidence and justify
the final extent of the ZTV used in the
assessment of landscape and visual
impacts, based on actual height
parameters. The ZTV should be agreed
with relevant consultation bodies where
possible. The ES should describe the
model and methodology used and should
provide information on the area covered
and the seasonal timing of any survey
work. The operational assessment should
consider the movement of aircraft along
the proposed runway, and stationary
aircraft at the proposed stands in the
The updated ZTV is provided on
Figure 15.1, Volume 2; the approach
to ZTV modelling, including height
parameters, is set out within Section 15.8. As indicated on Figure 15.1, the
updated ZTV allows for the height of
aircraft on the runway and taxiways,
enabling assessment of these aspects
to be taken forward. The updated
baseline information (including desktop
studies and surveys) is included within
Section 15.9. The outcomes of
engagement to date are set out under
the heading Technical engagement in
Section 15.3.

operational ZTV to ensure that these
elements are thoroughly assessed.
106 The Applicant should agree the viewpoints
to be included in its assessment with
relevant consultation bodies including the
HSPG and other affected local authorities,
where possible and should ensure that the
ES consider such viewpoints both during
the day and at night, and during both
winter and summer. The ES should
explain the reasons supporting the
inclusion of each viewpoint to be
assessed, and where relevant a
justification for excluding any viewpoints
that have been requested by the
consultation bodies. The ES should
include photographic visualisations of both
the baseline view and the view
incorporating the Proposed Development,
which should be numbered and cross-
referenced to accurately plotted locations
on an OS map of appropriate scale, which
should also show the angle of view. The
importance of local landmarks and
viewpoints, and the assessment of the
extent and direction of views from
properties should also be recorded. The
assessment should also take into
consideration any committed
development.
Viewpoints have been agreed through
engagement as set out under the
heading Technical engagement in
Section 15.3, (which includes a
justification for excluding any
viewpoints that have been requested
by consultation bodies) and have been
considered during the day and at
night, and during both winter and
summer within the PEIR. The PEIR
also sets out the reasons for including
each viewpoint. The viewpoints for the
PEIR are set out in Table 15.18,
Section 15.9 of this PEIR and the
locations shown on Figure 15.1, Volume 2. The PEIR includes
photographs of baseline views;
visualisations of the DCO Project
within views will be provided within the
ES rather than the PEIR. Viewpoints
included within the PEIR are
numbered and cross-referenced to
accurately plotted locations on an OS
map of appropriate scale, which also
shows the orientation of the view. The
description of views from each
viewpoint included within the PEIR
records any local landmarks, the
description also sets out the direction
and extent of views and identifies
where residential properties are
receptors in relation to viewpoints. The
assessment takes into account
committed development through the
consideration of future baseline
(Section 15.9) and cumulative
assessment (Section 15.11), as set
out in Chapter 5: Approach to the EIA.
107 The Scoping Report states that cumulative
landscape and visual amenity effects will
be assessed in accordance with the
approach set out in section 4.6 of the
Scoping Report. For the avoidance of
Existing developments are included
within the description of the baseline

doubt, the Inspectorate considers that
such assessment should include existing
and proposed developments, including
other proposals currently at the scoping
stage. It should also consider the
relevance of cumulative impacts in
protected landscapes, such as the route
of HS2 within the Chilterns AONB.
in line with the approach set out in
Chapter 5. Cumulative effects in
respect of HS2 and the Chiltern Hills
AONB are considered, where
relevant.
108 The Scoping Report states that mitigation
will be considered during the preparation
of a CoCP, and as part of the iterative
design development process. The
Applicant should ensure that the
effectiveness of any proposed mitigation
measures are thoroughly assessed in the
ES, describing the likely significant effects
of the Proposed Development both prior to
mitigation and residually so that it is
possible to understand the efficacy of
proposed mitigation measures. The ES
should also explain how measures
proposed to mitigate landscape and visual
effects, such as planting, may relate to
other aspects, for instance impacts on
ecological receptors. Appropriate cross-
reference should be made between
related aspects in the ES, such as
Biodiversity, and historic environment.
The landscape and visual amenity
methodology includes assessment
during construction, during the year of
opening (the year of maximum Air
Transport Movements (ATM) capacity
– the year of opening for the purposes
of landscape and visual amenity
assessment) and 15 years after
opening, to take account of the
efficacy of embedded (committed)
measures, through, for example, the
establishment of planting proposals to
integrate the proposals with landscape
character and ameliorate visual
effects. Design measures are set out
in Chapter 6: DCO Project description. No additional
environmental measures, over and
above embedded environmental
measures, are proposed at this stage.
Should additional environmental
measures be proposed, effects would
be considered prior to these additional
environmental measures and
residually. Measures proposed to
mitigate landscape and visual amenity
effects, such as planting, are referred
to by related aspects, such as
biodiversity and historic environment,
where relevant.
Technical engagement
Technical engagement has been ongoing with a number of prescribed and non-
prescribed consultation bodies and local authorities in relation to landscape and
visual amenity. A summary of engagement undertaken up to finalisation of this
PEIR is outlined in this section.

Natural England
Engagement with Natural England has been ongoing since June 2017 in the form
of meetings and document sharing. Focus areas of engagement with Natural
England have included:
The approach to assessment, including agreement of the study area radius
Relevant methodology guidance documents and their application
The use of published landscape character assessment material
Agreement of viewpoints
The approach to considering tranquillity as it relates to this chapter and visual
amenity
The approach to mitigation, including green infrastructure.
A nominal five-kilometre radius study area was agreed for assessment and
following further engagement with Natural England and Heathrow Strategic
Planning Group (HSPG), the study area has been extended beyond five-
kilometres in certain locations to encompass localised high points, and associated
viewpoints, in the landscape. The study area now extends further northwards to
hillsides at Harefield, further eastwards to Richmond Hill, further southwards to St.
Ann’s Hill, near Chertsey, and further west to Kennedy Park at Lynch Hill, in
Slough.
Relevant assessment guidance documents were discussed and agreed (as
included in Section 15.7 and Appendix 2.1).
It was agreed that the landscape and visual amenity assessment should refer to
the National Character Area relevant to the DCO Project and relevant local
landscape character assessments, with the recent Colne Valley Regional Park
(CVRP) Landscape Character Assessment forming a key reference document.
National Character Areas relevant to the DCO Project and relevant local character
areas have been considered in the assessment.
Natural England specifically requested a viewpoint from St. Ann’s Hill, which has
been incorporated as Viewpoint 17 within the PEIR.
It was agreed that tranquillity should be considered in relation to landscape
character and that should airspace considerations, and the noise assessment
thereof, indicate the need to consider tranquillity beyond the study area, a
high-level assessment of tranquillity (as it relates to landscape and visual amenity)
will be undertaken based on CAP 1616 guidance (as set out in Appendix 2.1).
This requires the assessment of the tranquillity aspect of the landscape in relation
to any relevant National Parks and AONBs (through the assessment process set
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.15 © Heathrow Airport Limited 2019
out in CAP 1616) with which Natural England agreed. Tranquillity is considered in
relation to landscape / townscape character within the study area. Whilst visual
effects are reported separately from landscape/townscape effects (as set out in
Section 15.1), they have a bearing on tranquillity and are therefore considered in
the broader perceptual analysis of tranquillity relating to landscapes and
townscapes. The tranquillity of nationally protected landscapes, beyond the study
area, is considered, based on CAP 1616 guidance, the spatial scope of which, in
relation to the DCO Project, is set out in Section 15.4.
The approach to mitigation, including green infrastructure, was discussed.
Highways England
Engagement with Highways England has been ongoing since March 2018 in the
form of meetings and document sharing. Focus areas of engagement with
Highways England have included:
The approach to assessment
Relevant methodology guidance documents and their application
The approach to mitigation, including green infrastructure.
Relevant assessment guidance documents were discussed and agreed (as
included in Appendix 2.1) and the approach to mitigation, including green
infrastructure, was discussed. The PEIR assessment has been carried out
accordingly.
Heathrow Strategic Planning Group (HSPG)
Engagement with HSPG has been ongoing since November 2017 in the form of
meetings and document sharing. Focus areas of engagement with HSPG have
included:
The approach to assessment, including the extent of study area required to
accommodate viewpoints
Relevant methodology guidance documents and their application
The use of published landscape and townscape character assessment material
Agreement of viewpoints
The approach to mitigation, including green infrastructure.
Following further engagement with Natural England and HSPG (including
responses to the Scoping Report), the study area has been extended, as set out in
paragraph 15.3.8.
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.16 © Heathrow Airport Limited 2019
Relevant assessment guidance documents (as included in Appendix 2.1) were
discussed.
The CVRP Landscape Character Assessment was identified as a key reference
document.
The following viewpoints have been agreed with stakeholders:
Hillside south of Harefield (requested by CVRP), included in PEIR as Viewpoint
33
Osterley Park (requested by London Borough of Hounslow), included in PEIR
as Viewpoint 8
King Henry VIII’s Mound, Richmond Hill (requested by HSPG), included in
PEIR as Viewpoint 10
Stanwell Conservation Area (requested by Surrey County Council), included in
PEIR as Viewpoint 14
Staines Reservoir (requested by CVRP), included in PEIR as Viewpoint 15
Sutton Lane at M4 (requested by Slough Borough Council and South Bucks
District Council), included in PEIR as Viewpoint 25
Kennedy Park Viewing Mound (requested by Slough Borough Council),
included in PEIR as Viewpoint 28
Stakeholders requested that the following viewpoints are considered by Heathrow,
however these have not been taken forward for the reasons outlined below:
Entrance to Legoland (requested by consultant to HSPG)
Datchet Water Sailing Club at the Thames Water Queen Mother Reservoir
(requested by Slough Borough Council and CVRP).
Following investigations, the viewpoints from the entrance to Legoland and
Datchet Water Sailing Club, at the Queen Mother Reservoir, have been excluded
for the following reasons: These are private leisure facilities where users of the
facilities will be focussed on their chosen leisure pursuits rather than any views of
the DCO Project. Additionally, in the case of Legoland, the viewpoint would be
very distant; in the case of Datchet Water Sailing Club sailors’ views to areas
beyond the waterbody are obscured by reservoir embankments.
The approach to mitigation, including green infrastructure, was discussed.

15.4 Scope of the assessment
Overview
This section describes the spatial and temporal scope for the assessment as it
applies to landscape and visual amenity and outlines the receptors on which
assessment has been undertaken.
This scope has been developed as the DCO Project has evolved and responds to
feedback received to date as detailed in Section 15.3. The information presented
in the PEIR is by its nature preliminary and should not be considered a “draft” ES
(in accordance with PINS advice note seven). Further scope refinement may be
required to take full account of the preferred DCO Project design and subsequent
engagement.
Spatial scope and study area
As a result of ongoing technical engagement with stakeholders and as the DCO
Project has developed and land potentially required has been refined, the study
area has evolved to reflect this. The study area for landscape and visual amenity
(which contains the ZTV) is based on the draft DCO limits shown in Figure 15.1 plus a nominal five-kilometre radius around the extent of that boundary. Further to
the engagement set out in Section 15.3, this area has been extended beyond five-
kilometres in certain locations to encompass localised high points in the
landscape. These locations comprise hillsides at Harefield (north of the DCO
Project), Richmond Hill (east of the DCO Project), St. Ann’s Hill, near Chertsey
(south of the DCO Project), and Kennedy Park at Lynch Hill, in Slough (west of the
DCO Project). This study area is shown on Figure 15.1. The study area
represents the ZOI regarding the main spatial scope of assessment.
In the case of assessing effects resulting from aircraft movements in relation to the
tranquillity aspect of the landscape, CAP 1616 advises that National Park and
AONB landscapes should be considered within the area where Heathrow related
aircraft could fly below 7,000 feet above mean sea level (amsl). However, as
explained in Chapter 5, Heathrow is currently taking forward an Airspace Change
Process in relation to the operation of Heathrow Airport, in advance of and, if
granted, in response to the DCO Project. In line with national airspace policy,
Heathrow’s detailed Airspace Change Process, that would respond to the DCO
Project, would be supported by an environmental assessment and would be
consulted on as part of a separate decision-making process established by the
Civil Aviation Authority. This would be within the Noise Envelope set by the DCO
and would include an assessment of any proposed change in overflight of relevant
National Parks and AONBs. The ANPS requires an assessment of aircraft noise
and this is presented in Chapter 17.
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.18 © Heathrow Airport Limited 2019
As set out in Chapter 17, air navigation guidance indicates that below 4,000 feet
there is a strong likelihood that aircraft could create levels of noise exposure
above the Lowest Observed Adverse Effect Levels (LOAELs). LOAELs are
regarded as the point at which adverse effects begin to be seen on a community
basis. Informed by this and in line with the Scoping Report and Scoping Opinion,
the preliminary noise assessment has been undertaken within the area where
Heathrow related aircraft could fly below 4,000 feet amsl. The Chiltern Hills AONB
is the only AONB within the area where Heathrow related aircraft could fly below
4,000 feet amsl, as shown on Figure 15.2, Volume 2. There are no National
Parks within this area. The aircraft noise assessment is based on a number of
indicative airspace design ‘test-cases’ that have been developed purely for the
PEIR noise assessment. In turn, consideration of the tranquillity aspect of the
landscape has been informed by the noise assessment.
Temporal scope
The DCO Project would be developed in a phased approach meaning that in some
periods and / or some locations both construction and operational activities would
take place in parallel. Three phases have been identified to broadly correspond
with the most prevalent activities that would arise as a result of the DCO Project.
A number of years have been selected for assessment within each phase, the
approach for which is described in Chapter 5.
The assessment of landscape and visual amenity assesses the following for this
PEIR, which is consistent with IAN 135/10 guidance:
Construction activities and interim ATM activity prior to year of maximum ATM
capacity: c.2022 to 2050
Year of maximum ATM capacity (‘opening year’ for the purposes of landscape
and visual amenity assessment): c.2050
Design year (15 years after the ‘opening year’ for the purposes of landscape
and visual amenity assessment): c.2065
Temporary construction activities are expected to occur variously at locations
within the draft DCO limits, during the period c.2022 to 2050. Assessment
conclusions have been applied to the expected peak of construction activity in
relation to each character area or viewpoint over that time period; as such it should
be noted this level of effect would not occur or be sustained throughout the
construction period. The assessment will be reviewed and updated for the ES,
when further information will be available.

Receptors
The spatial and temporal scope of the assessment enables the identification of
receptors which may experience a change as a result of the DCO Project. The
receptors identified that may experience likely significant effects for [aspect] are
outlined in Table 15.4.
Table 15.4: Receptors requiring assessment for landscape and visual amenity

2. Townscape character types
3. Townscape character areas
Visual Amenity 1. Visual receptors
The list of receptors will be kept under review during the EIA as more detailed
information is obtained during baseline surveys and other forms of data collection
by other aspects and will be reflected in the final ES.
Identification of potential effects
The types of effects that have been considered in this section relate to changes to
landscape character and visual amenity.
Potential effects on landscape and visual amenity receptors that have been
scoped in for assessment are summarised in Table 15.5.

15.5 Embedded environmental measures
The DCO Project will consider a number of environmental measures to avoid or
minimise likely significant effects. This approach is described in Chapter 5. Those
embedded environmental measures that influence the assessment of landscape
and visual amenity are set out in Table 15.6.
Good practice environmental measures would occur with or without input from the
EIA feeding into the design process. They include actions that would be
undertaken to meet other existing legislative requirements, or that are considered
to be standard practices. Those good practice environmental measures that
influence the assessment of landscape and visual amenity are set out in Table 15.7.

controlled through protection of existing elements of the landscape that are
to be retained; careful design and management of temporary construction
components in response to landscape character and visual amenity; and the
effective implementation of operational design measures, as early as
possible during the construction programme, which have a role in mitigating
landscape and visual impacts.

15.7 Assessment methodology for the PEIR
Assessment methodology evolution
At this stage of the EIA, the DCO Project is still under development and is the
subject of statutory consultation. The likely significant environmental effects are
presented at this preliminary stage. Further, more detailed assessment work will
be undertaken between PEIR and preparation of the ES on the final DCO Project.
The methodology for the ES assessment may therefore develop further from that
used for the PEIR. There are no anticipated changes in the assessment
methodology at this stage, however the landscape and visual amenity assessment
will be updated to take account of engagement, additional baseline information,
DCO Project development and information relating to cumulative effects.
The generic project-wide approach to the assessment methodology is set out in
Section 5.6 of Chapter 5. This has informed the approach used in this landscape
and visual amenity assessment.
The DCO Project encompasses a range of development and infrastructure
proposals, including highway proposals. The LVIA for the DCO Project is informed
principally by good practice guidance set out in Appendix 2.1. Guidelines for
Landscape and Visual Impact Assessment: Third Edition (GLVIA3), Landscape
Institute (LI) and Institute of Environmental Management and Assessment (IEMA)
(2013), does not set out specific significance criteria, rather the guidance
advocates use of clear methods by which reasoned professional judgments should
be applied. To aid consistency in assessing landscape and visual amenity effects
across the DCO Project, the significance criteria set out in Interim Advice Note
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.28 © Heathrow Airport Limited 2019
(IAN) 135/10 - Landscape and Visual Effects Assessment, Highways Agency
(2010), have been applied as guidance, as set out in Table 15.11 to Table 15.14.
The criteria provided in Table 15.11 to Table 15.14 apply to the assessment of
both construction and operation.
In the case of assessing effects resulting from aircraft movements in relation to the
tranquillity aspect of the landscape, which concerns National Parks and AONBs,
CAP 1616 advises that the criteria provided in WebTAG (Transport Analysis
Guidance - www.gov.uk/guidance/transport-analysis-guidance-webtag) under
‘Landscape’ (TAG Unit A3 – Section 6) should be applied. These criteria relate to
a range of potential landscape effects, many of which, including physical change
to the landscape, would not result from aircraft movements in the sky; therefore,
only those criteria that are relevant to airspace, such as those concerning the
setting of the landscape, have been considered. These criteria only relate to
overall assessment scores regarding significance of effect, which are provided in
Table 15.15, therefore the landscape criteria set out in Table 15.11 have been
applied in relation to receptor sensitivity and the landscape criteria set out in Table 15.11 have been applied in relation to magnitude of effect. As set out in paragraph
15.4.6, above, the assessment takes into account information provided within
Chapter 17, including the extent of the LOAEL.
Significance evaluation methodology
Guidance on determining the sensitivity of receptors is given in Table 15.11. In
relation to visual receptors, these include residents and visitors to the local area.
Table 15.11: Definitions of receptor sensitivity
Sensitivity Criteria
High Landscape:
Landscapes which by nature of their character would be unable to accommodate
change of the type proposed. Typically, these would be:
1. Of high quality with distinctive elements and features making a positive
contribution to character and sense of place
2. Likely to be designated but the aspects which underpin such value may
also be present outside designated areas, especially at the local scale
3. Areas of special recognised value through use, perception or historic
and cultural associations
4. Likely to contain features and elements that are rare and could not be
replaced.
Visual Amenity:
1. Residential properties
2. Users of Public Rights of Way (PRoW) or other recreational trails (e.g.
National Trails, footpaths, bridleways, etc.); and
3. Users of recreational facilities where the purpose of that recreation is
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity

Sensitivity Criteria
enjoyment of the countryside (e.g. Country Parks, National Trust or
other access land).
Moderate
Landscape:
Landscapes which by nature of their character would be able to partly
accommodate change of the type proposed. Typically, these would be:
Comprised of commonplace elements and features creating generally
unremarkable character, but with some sense of place
1. Locally designated, or their value may be expressed through non-
statutory local publications
2. Containing some features of value through use, perception or historic
and cultural associations
3. Likely to contain some features and elements that could not be replaced.
Visual Amenity:
1. Outdoor workers
2. Users of scenic roads, railways or waterways or users of designated
tourist routes
3. Schools and other institutional buildings and their outdoor areas.
Low
Landscape:
Landscapes which by nature of their character would be able to accommodate
change of the type proposed. Typically, these would be:
1. Comprised of some features and elements that are discordant, derelict
or in decline, resulting in indistinct character with little or no sense of
place
2. Not designated
3. Containing few, if any, features of value through use, perception or
historic and cultural associations
4. Likely to contain few, if any, features and elements that could not be
replaced.
Visual Amenity:
1. Indoor workers
2. Users of main roads (e.g. trunk roads) or passengers in public transport
on main arterial routes
3. Users of recreational facilities where the purpose of that recreation is not
related to the view (e.g. sports facilities).
Guidance on assessing the magnitude of change is provided in Table 15.12
Table 15.12: Definitions of landscape and visual amenity magnitude of change
Magnitude Criteria
Major Landscape:
Adverse - Total loss or large-scale damage to existing character or distinctive
features and elements and / or the addition of new but uncharacteristic

Adverse / Beneficial - The project, or a part of it, would form a noticeable
feature or element of the view which is readily apparent to the receptor.
Minor Landscape:
Adverse - Slight loss or damage to existing character or features and elements
and / or the addition of new but uncharacteristic features and elements; or
Beneficial - Slight improvement of character by the restoration of existing
features and elements and / or the removal of uncharacteristic features and
elements, or by the addition of new characteristic elements.
Visual Amenity:
Adverse / Beneficial - The project, or a part of it, would be perceptible but not
alter the overall balance of features and elements that comprise the existing
view.
Negligible Landscape:
Adverse - Barely noticeable loss or damage to existing character or features
and elements and / or the addition of new but uncharacteristic features and
elements or
Beneficial - Barely noticeable improvement of character by the restoration of
existing features and elements and / or the removal of uncharacteristic features
and elements, or by the addition of new characteristic elements.
Visual Amenity:
Adverse / Beneficial - Only a very small part of the project would be
discernible, or it is at such a distance that it would form a barely noticeable
feature or element of the view.
No Change Landscape:
No noticeable loss, damage or alteration to character or features or elements.
Visual Amenity:
No part of the project, or work or activity associated with it, is discernible.
The significance of effect is determined using the framework set out in Table 15.13 as a guide. Where more than one significance outcome is possible,
professional judgment is applied to determine which is the most appropriate

classification, on a case by case basis. The process applies a precautionary
approach, whereby caution is exercised in order that professional judgement is
inclined towards concluding the worst outcome in the event of uncertainty
regarding selection from more than one possible outcome. Only ‘Large’ or ‘Very
Large’ effects are considered likely significant effects for the purposes of the
Infrastructure Planning (Environmental Impact Assessment) Regulations 2017 (the
EIA Regulations), as is consistent with HA 205/08 - Assessment and Management
of Environmental Effects, Highways Agency (2008).

Significance of effect Criteria
Very Large Landscape:
Beneficial - No criteria provided as schemes are not anticipated to merit this score.
Adverse - The scheme would result in exceptionally severe adverse impacts on
the landscape because it:
1. Is at complete variance with the landform, scale and pattern of the
landscape
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.34 © Heathrow Airport Limited 2019
Significance of effect Criteria
2. Is highly visual and extremely intrusive, destroying fine and valued views
both into and across the area
3. Would irrevocably damage or degrade, badly diminish or even destroy the
integrity of characteristics and elements and their setting
4. Would cause a very high quality or highly vulnerable landscape to be
irrevocably changed and its quality very considerably diminished
5. Could not be integrated: there are no environmental design measures that
would protect or replace the loss of a nationally important landscape
6. Cannot be reconciled with government policy for the protection of
nationally recognised countryside.
Large Landscape:
Beneficial - The scheme provides an opportunity to greatly enhance the landscape
because:
1. It greatly enhances the character (including quality and value) of the
landscape
2. It creates an iconic high quality feature and / or series of elements
3. It enables a sense of place, scale and quality to be restored in an area
formerly of high landscape quality
4. Note that very few, if any, schemes are likely to merit this score.
Adverse - The scheme is very damaging to the landscape in that it:
1. Is at considerable variance with the landform, scale and pattern of the
landscape
2. Is visually intrusive and would disrupt fine and valued views of the area
3. Is likely to degrade, diminish or even destroy the integrity of a range of
characteristics and elements and their setting
4. Will be substantially damaging to a high quality or highly vulnerable
landscape, causing it to change and be considerably diminished in quality
5. Cannot be adequately integrated
6. Is in serious conflict with government policy for the protection of nationally
recognised countryside.
Moderate Landscape:
Beneficial - The scheme provides an opportunity to enhance the landscape
because:
1. It fits very well with the scale, landform and pattern of the landscape
2. There is potential, through environmental design measures, to enable the
restoration of characteristics, partially lost or diminished
3. As the result of changes resulting from intensive farming or inappropriate
development
4. It will enable a sense of place and scale to be restored through well-
designed planting and environmental design measures, that is,
characteristics are enhanced through the use of local materials and
species used to fit the scheme into the landscape
5. It enables some sense of quality to be restored or enhanced through
beneficial landscaping and sensitive design in a landscape which is not of
any formally recognised quality
6. It furthers government objectives to regenerate degraded countryside
Adverse - The scheme is:
1. Out of scale with the landscape, or at odds with the local pattern and

2. Visually intrusive and will adversely impact on the landscape
3. Not possible to fully integrate, that is, environmental design measures will
not prevent the scheme from scarring the landscape in the longer term as
some features of interest will be partly destroyed or their setting reduced
or removed
4. Will have an adverse impact on a landscape of recognised quality or on
vulnerable and important characteristics or elements
5. In conflict with local and national policies to protect open land and
nationally recognised countryside
Slight Landscape:
Beneficial - The scheme:
1. Fits well with the scale, landform and pattern of the landscape
2. Incorporates environmental design measures to ensure they will blend in
well with surrounding landscape
3. Will enable some sense of place and scale to be restored through well-
designed planting and environmental design measures
4. Maintains or enhances existing landscape character in an area which is
not a designated landscape, nor vulnerable to change
5. Avoids conflict with government policy towards protection of the
countryside
Adverse - The scheme:
1. Does not quite fit the landform and scale of the landscape
2. Although not very visually intrusive, will impact on certain views into and
across the area
3. Cannot be completely integrated because of the nature of the scheme
itself or the character of the landscape through which it passes
4. Affects an area of recognised landscape quality
5. Conflicts with local planning authority policies for protecting the local
character of the countryside
Neutral Landscape:
The scheme is well designed to:
1. Complement the scale, landform and pattern of the landscape
2. Incorporate environmental design measures to ensure that the scheme
will blend in well with surrounding landscape characteristics and
landscape elements
3. Avoid being visually intrusive nor have an adverse effect on the current
level of tranquillity of the landscape through which the scheme passes
4. Maintain existing landscape character in an area which is not a designated
landscape, that is, neither national or local high quality, nor is it vulnerable
to change
5. Avoid conflict with government policy towards protection of the countryside

15.8 Assumptions and limitations of this PEIR
Chapter 6 describes preliminary location and height parameters of the DCO
Project. These have been taken into account for the purposes of PEIR stage ZTV
modelling. The actual parameters of the DCO Project are subject to ongoing
design development and refinement. The baseline data sources used in ZTV
modelling are set out in Table 15.8, with further detail provided on Figure 15.1.
The preliminary ZTV presented in PEIR will be updated as the DCO Project
progresses.
15.9 Overall baseline
Current baseline
Landscape
The DCO Project falls within National Character Area (NCA) 115: Thames Valley1.
Key characteristics of this character area, are as follows:
“Flat and low-lying land, rising to low, river-terraced hills, which include the
prominent local outcrop of chalk on which Windsor Castle sits.
The underlying geology is dominated by the London Clay which, over much of the
area, is overlain by river-lain sands and gravels.
The numerous hydrological features provide unity to an area which otherwise
lacks homogeny; these features include the River Thames and its tributaries,
streams, lakes, canals and open waterbodies (the result of restored gravel
workings).
Woodlands characterise the north-western area, with the wooded character
extending up to the southern edge of the Chiltern Hills.
Farming is limited. Where it survives, grazed pasture is the major land use within a
generally open, flat and featureless landscape. The field pattern is medium-scale
and irregular, with smaller fields to the west. Localised areas of species-rich hay
meadows provide a splash of colour in summer.
Although densely populated and developed, pockets of woodland, open grassland,
parkland, wetlands and intimate meadows provide escape and tranquillity, and
include a variety of habitats supporting important populations of many species,
notably stag beetle, shoveler, gadwall and other invertebrates and wildfowl.

Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity

Towards London in the east, the natural character of the area is overtaken by
urban influences: a dense network of roads (including the M25 corridor), Heathrow
Airport, railway lines, golf courses, pylon lines, reservoirs, extensive mineral
extraction and numerous flooded gravel pits.
There are small but biologically important areas of lowland heathland – especially
on higher sandy ground in the north – and a small area to the south falls within the
Thames Basin Heaths Special Protection Area (SPA) buffer zone.
To the south, the open Thames flood plain dominates, with its associated flat
grazing land, becoming characterised by a number of formal historic landscapes
on higher ground. Between Hampton and Kew, the River Thames forms the focus
of a series of designed landscapes.
The area has an urban character, and there are very few villages of more
traditional character, although almost half of the area is greenbelt land and
development has been restricted in areas like Crown Estate land and Eton College
grounds.
The river is closely associated with numerous historic places and cultural events,
such as the signing of Magna Carta at Runnymede. Tourists from all over the
world are drawn to the rich heritage of the area, flocking to attractions like
Hampton Court Palace and Windsor Castle.
The area is important for recreation, both for residents and visitors. Historic
parkland and commons provide access to green space, the Thames Path National
Trail runs the length of the NCA, and a variety of activities are enjoyed on the river
and other waterbodies.”
In relation to tranquillity, NCA 115 is further described as follows:
“Based on the CPRE map of Tranquillity (2006) none of this NCA can be officially
considered as tranquil. The lowest scores for tranquillity are around the urban
areas and Heathrow Airport. Expanses of parkland such as Windsor Great Park
score medium tranquillity...The 2007 Intrusion Map (CPRE) shows the extent to
which rural landscapes are ‘intruded on’ from urban development, noise (primarily
traffic noise), and other sources of visual and auditory intrusion. This shows that
almost the entire NCA is disturbed by visual and auditory intrusion.”
As identified in NCA 115, Heathrow Airport, which includes transport infrastructure
and buildings, is a noteworthy element within the wider Thames Valley landscape.
Near Heathrow Airport, the lowland landscape includes semi-rural characteristics
of the Colne Valley and associated historic villages, together with suburban areas
of Greater London further east. It is a landscape generally characterised by urban
influences, including a busy major road and rail network, together with substantial
areas of industrial, commercial and residential development. The more rural
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.38 © Heathrow Airport Limited 2019
elements are fragmented and include riparian corridors and grazed common land,
such as Staines Moor, however urban features, including buildings and roads,
generally feature in the backdrop to these areas.
At a local level, the landscape character assessments identified in Table 15.16
provide information regarding local landscape character areas. Local landscape /
townscape character areas / types are shown on Figure 15.3. Descriptions of
these, including key characteristics and tranquillity considerations, are set out in
Appendix 15.1. This landscape / townscape character analysis considers
biodiversity and heritage influences; biodiversity designations are identified and
shown within Chapter 8, historic environment designations are identified and
shown within Chapter 13. Policy analysis relevant to biodiversity and heritage
considerations is also provided in these chapters, as appropriate. Landscape
character areas, and respective sensitivity, within the study area are set out in
Table 15.16. Figure 15.1 shows designations which contribute to the evaluation of
landscape and townscape sensitivity. The designations referred to in Table 15.16 are those for which landscape value is expressed through local planning policy
(refer to Section 15.2).

In the case of considering tranquillity regarding aircraft movements in relation to
the landscape of National Parks and AONBs, CAP 1616 advises that WebTAG
under ‘Landscape’ (TAG Unit A3 – Section 6) should be applied. In accordance
with WebTAG Unit A3 – Section 6, tranquillity has been described, based on
published documents, and considered in relation to the scale it matters, rarity,
importance and substitutability, as set out in Table 15.17.

Chiltern Hills AONB The Chilterns Area of Outstanding Natural
Beauty Management Plan 2014-2019,
produced by The Chilterns Conservation
Board (2014), identifies that, in terms of the
special qualities of the AONB, visitors are
seeking peace and quiet as part of their visit
and that whilst by no means a wilderness the
Chilterns does offer relative tranquillity
compared to surrounding towns and cities.
The Management Plan sets out the following
policies in relation to tranquillity:
Policy L14: Tranquillity should be conserved
and restored when all development and major
landscape management is planned.
Policy D14: The special qualities of the
Chilterns should be conserved and enhanced
Scale it matters: Nationally designated landscape
and therefore matters at a national
scale.
Rarity: One of a limited number of such
protected areas and therefore rare

and therefore of national
importance.

by reducing the noise and other detrimental
impacts on tranquillity generated by the
development and operation of transport
networks and services and other
infrastructure.
Policy D15: A reduction in the number and
frequency of night flights over the AONB and a
reconsideration of night flight policies,
particularly at Luton Airport, should be sought.
Policy UE18: Tranquillity should be conserved
by resisting noisy/damaging activities. A
reduction in the level of noise and other forms
of pollution caused by development and
transport infrastructure should be sought.
Notwithstanding the above, the Management
Plan highlights that the tranquillity of the
Chilterns is being eroded due to built up
areas, railways, traffic noise (notably the M40
and several of the trunk roads) and the
increase in over-flying by aircraft of all types
using Luton, Heathrow and local airfields. In
addition, High Speed 2 is identified as a
potential future contributor to reduced
tranquillity.
As indicated on Figure 15.2, Volume 2, which
shows 2017 flight track information, there is

approximately ninety degrees in the direction of the view. Visual receptors are
described in relation to each representative viewpoint within Table 15.18. As set
out in Section 15.3, viewpoint locations have been informed by the engagement
process.
Figure 15.1 shows the extents of designations which contribute to informed
judgement regarding visual sensitivity. Designations relating to biodiversity are
identified and shown within Chapter 8, designations relating to the historic
environment are identified and shown within Chapter 13, this information is
therefore not duplicated as part of the assessment. In some cases, nature
conservation and historic environment sites are also recreational areas, such as
Country Parks, and visual effects on these areas are considered through the
representative viewpoints identified. For example, Staines Moor (represented by
Viewpoint 19) is a Site of Special Scientific Interest (SSSI) that includes Open
Access Land, and Bedfont Lakes Country Park (represented by Viewpoint 12) and
Hounslow Heath (represented by Viewpoint 9) are informal recreational areas that
are also Local Nature Reserves Bedfont Lakes Country Park also falls within a
Site of Importance for Nature Conservation (SINC).
Viewpoint selection has taken account of views identified within the All London
Green Grid Area 10: River Colne and Crane Area Framework, Mayor of London
(2011), and a protected view identified in the London Borough of Richmond upon
Thames Adopted Local Plan, London Borough of Richmond upon Thames Council
(2011), as indicated on Figure 15.1. Viewpoints 4 (Stockley Park), 12 (Bedfont
Lakes Country Park) and 29 (Harmondsworth Moor) are locations of views
identified within the All London Green Grid Area 10 Framework. Viewpoint 10
(King Henry VIII’s Mound) is a protected view identified in the London Borough of
Richmond upon Thames Adopted Local Plan. It is recognised that there are valued
views within the Windsor urban area, however the ZTV indicates that the visual
influence of DCO Project development and infrastructure would be restricted within
Windsor; this is primarily due to intervening landform and built development.
Considering this, Viewpoint 22 has been included, which lies close to Windsor
rather than within the Windsor urban area. As the DCO Project design has
developed, adjustments have been made to viewpoints identified in the Scoping
Report. Principally, a viewpoint at Palmers Moor Lane (Viewpoint 24 in the
Scoping Report) has been moved to a Public Footpath off Iver Lane (Viewpoint 28
identified on Figure 15.1) due to a change in the location of the DCO Project flood
storage areas. Sequential views are considered through the inclusion of multiple
viewpoints on or near a given linear route, such as the Colne Valley Trail/Way,
where relevant. Proposed locations for such sequential representative viewpoints
are also included within Table 15.18.

Future baseline
In the absence of the DCO Project, there is likely to be a change in baseline
conditions as a result of other development being pursued at Heathrow Airport.
The Kilobox Apron Development and Runway Access Taxiway projects, described
in Chapter 5, would be completed prior to the commencement of construction of
the DCO Project. The Kilobox Apron Development project is not expected to
conspicuously alter baseline landscape and visual amenity conditions, as it would
sit within the existing Heathrow Airport footprint and predominantly below ground.
The Runway Access Taxiway project would similarly sit within the existing
Heathrow Airport footprint such that landscape character and visual amenity,
already heavily influenced by airport infrastructure and development, are not
expected to notably alter. The assessment presented in Section 15.10 assumes
the presence of these developments in the baseline, against which the effects of
the DCO Project are compared.
Additional Heathrow ASD may also come forward in the future (with their
construction and operation phases overlapping with the construction and / or
operation phases of the DCO Project). Such development is presented within
Section 15.11.
There would also be other changes in baseline conditions in the wider area as a
result of land use changes through development un-related to Heathrow Airport.
Such ‘other development’ could result in new receptors or result in other
cumulative effects with the DCO Project. Where these developments are built out
before the construction of the DCO Project commences, or where the construction
and operation phases of these developments overlap with the construction and / or
operation phases of the DCO Project, they are assessed in Section 15.11.
15.10 Assessment of landscape and visual amenity effects
Effects would vary during the course of the construction phase and concluding
assessment of effect categories take account of the expected peak of construction
activity in relation to each character area or viewpoint; this level of effect would not
occur or be sustained throughout the construction period.
Landscape
Table 15.19 sets out the preliminary assessment of effects on landscape in

would include creation of worker offices,
movement of plant and vehicles and material
stockpiling together with creation of
compounds and construction components
therein. This would result in temporary effects
on the landscape – including a reduction in

Harmondsworth to Stanwell Moor LCA (CVRP) Sensitivity: Moderate
The DCO Project would physically affect this
landscape character area over an extensive
area. This is due to works including
demolition of buildings (including those within
Longford Conservation Area and
Harmondsworth Conservation Area),
construction of the proposed runway and
ASD (including the southern parkway),
together with highways proposals (including
the M25, A4 and A3044), railhead, utilities
diversions, water treatment and surface
water proposals (including flood storage
areas and river diversions). Construction
activities would include demolition, creation
of worker offices, movement of plant and
vehicles and material stockpiling together
with creation of compounds and construction
components therein. This would result in
temporary effects on the landscape –
including a reduction in tranquillity. It is
expected that increased ATMs in the sky
would also contribute to a reduction in
tranquillity. Preliminary conclusions drawn at
this stage are Major Adverse magnitude; Large Adverse significance.
The DCO Project would physically
affect this landscape character area
over a large proportion of the
character area. This is due to
introduction of the proposed runway,
which would replace historic features

southern parkway) together with
highways proposals (including the
M25, A4 and A3044), railhead, utilities
diversions, water treatment and
surface water proposals (including
flood storage areas and river
diversions). Although there are
existing influences of industry,
infrastructure and built development
within the landscape, the proposals
would result in the loss of valued
elements within Conservation Areas
and further urbanisation (in the form
of built development and
infrastructure) would occur over a
large proportion of the character area.
It is expected that operational

Harmondsworth Open Gravel Terrace (K1) LCA (London Borough of Hillingdon) Sensitivity: Moderate
The DCO Project would physically affect this
landscape character area over an extensive
area. This is due to works including
demolition of buildings, construction of the
proposed runway and ASD, highways
proposals, utilities diversions and surface
water proposals. Construction activities
would include demolition, creation of worker
offices, movement of plant and vehicles and
material
stockpiling together with
creation of compounds and construction
components
therein. This would result in temporary effects
on the landscape – including a reduction in
tranquillity. It is expected that increased
ATMs in the sky would also contribute to a
reduction in tranquillity. Preliminary
conclusions drawn at this stage are Major Adverse magnitude; Large Adverse significance.
The DCO Project would physically
affect this landscape character area
over a large proportion of the
character area. This is due to
introduction of the proposed runway
and ASD, which would replace semi-
rural landscape elements such as
farmland, together with the
introduction of highways proposals,
utilities diversions and surface water
proposals. Although there are existing
influences of industry, infrastructure
and built development within the
landscape, the proposals would result
in further urbanisation over a large
proportion of the character area. It is
expected that operational
infrastructure and development
proposals, with increased ATMs in the
sky, would result in noticeable
reduction in tranquillity. Preliminary
conclusions drawn at this stage are
Major Adverse magnitude; Large Adverse significance.
It is expected that maturing green
infrastructure proposals would
temper effects through helping to
integrate the DCO Project with the
surrounding landscape. However,
the urbanising effects of

Harlington Open Gravel Terrace (K2) LCA (London Borough of Hillingdon) Sensitivity: Moderate
The DCO Project would physically affect this
landscape character area due to works
including construction of ASD (including the
northern parkway), highways proposals and
airport related commercial development.
Construction activities would include creation
of worker offices, movement of plant and
vehicles and material
stockpiling together with
creation of compounds and construction
components
therein. This would result in temporary effects
on the landscape – including a reduction in
tranquillity. Highways proposals would be
constructed in the early stages of the
construction programme (prior to 2027), such
that associated effects would be experienced
during these stages. The northern parkway
and airport related development would not be
constructed until the later stages of the
construction period (after 2030) and therefore
associated effects would not occur until then.
It is expected that increased ATMs in the sky
would also contribute to a reduction in
tranquillity. Preliminary conclusions drawn at
this stage are Major Adverse magnitude; Large Adverse significance.
The DCO Project would physically

Historic Core TCT (London Borough of Hillingdon) Sensitivity: Moderate
The DCO Project would physically affect this

works including demolition of buildings and
construction of the proposed runway within
Harmondsworth Conservation Area. In
addition, the settings of the remaining part of
Harmondsworth, Sipson and Harlington
would be affected by construction of the
proposed runway, and ASD (including the
northern parkway), highways proposals,
utilities diversions and surface water
proposals. Construction activities would
include demolition, creation of worker offices,
movement of plant and vehicles and material
stockpiling together with creation of
compounds and construction components
therein. This would result in temporary effects
on the townscape – including a reduction in
tranquillity. It is expected that increased
ATMs in the sky would also contribute to a
noticeable reduction in tranquillity within parts
of the townscape. Preliminary conclusions
drawn at this stage are Major Adverse magnitude; Large Adverse significance.
The DCO Project would physically

Inter-war/Suburb/Metroland TCT (London Borough of Hillingdon) Sensitivity: Moderate
The DCO Project would physically affect this
townscape character type primarily due to
highways works at Sipson and construction
of rail track proposals (in the Fray’s sidings
area) and community facilities at West
Drayton. DCO Project construction would
also affect the settings of Sipson, West
Drayton, Hayes and Harlington, which fall
within the character type, as a result of
construction of the proposed runway, ASD
(including the northern parkway), and
highways proposals. Construction activities
would include creation of worker offices,
movement of plant and vehicles and material
stockpiling together with creation of
compounds and construction components
therein. This would result in temporary effects
on the townscape – including a reduction in
tranquillity. Increased ATMs in the sky are
also expected to contribute to a reduction in
tranquillity within the townscape. Preliminary
conclusions drawn at this stage are Major Adverse magnitude; Large Adverse significance.

there would be increased ATMs in the sky,
with limited reduction in tranquillity due to

The DCO Project would not physically affect
this townscape character area. However,
works including construction of the proposed
runway and ASD, together with related
elements which include highways, utilities
diversions and surface water proposals
would occur within the immediate setting of
the townscape. Construction activities would
include creation of worker offices, movement
of plant and vehicles and material stockpiling
together with creation of compounds and
construction components therein. This would
result in temporary effects on landscape
setting – including a localised reduction in
tranquillity. It is expected that there would be
increased ATMs in the sky, with limited

In the case of assessing effects regarding aircraft movements in relation to the
tranquillity aspect of the landscape of National Parks and AONBs, CAP 1616
advises that WebTAG under ‘Landscape’ (TAG Unit A3 – Section 6) criteria should
be applied. The preliminary assessment set out in Table 15.20 has been carried
out accordingly.
Table 15.20: Preliminary effects concerning the tranquillity aspect of the landscape relating to National Parks and AONBs
National Park or AONB Tranquillity – WebTAG Step 4: Impact; WebTAG Step 5: Assessment Score
Chiltern Hills AONB
Sensitivity: High The preliminary assessment set out in Chapter 17, based on the indicative
airspace designs considered, indicates that there are not expected to be
significant noise effects within the Chiltern Hills AONB, in the area where
Heathrow Airport related aircraft could fly below 4,000 ft amsl, The LOAEL (the
point at which adverse effects begin to be seen on a community basis) for any of
the indicative airspace test cases, as indicated in Chapter 17, would not interact
with the Chilterns AONB and hence the level of any aircraft noise exposure on
the closest part of the Chilterns AONB would be lower than the LOAEL. In
addition, given that there is already considerable existing Heathrow Airport
related aircraft activity in this area (as set out in Section 15.9), there are not
expected to be significant changes in the visual influences of aircraft on this area
of the Chiltern Hills AONB as a result of anticipated airspace design changes.
With regard to assessment score, preliminary conclusions drawn at this stage
are Negligible Adverse magnitude; Slight Adverse significance.

1: High Street, Harmondsworth, looking south.
Visual sensitivity: High
Construction activities
associated with the
DCO Project, namely the
creation and use of
construction working areas,
demolition, movement of
plant (including cranes) and
vehicles, and material
stockpiles, would introduce
disruptive visual elements
during construction. More
aircraft approaching and
leaving Heathrow Airport
would be seen in the
background than in the
existing scenario, due to the
increase in ATMs.
Preliminary conclusions
drawn at this stage are
Major Adverse magnitude; Large Adverse significance.
The Airport perimeter noise
mitigation buffer (up to 5m
high) would be clearly visible.
However, it is expected that
high quality design proposals,
including a material finish
which responds to the local
context, together with
landscape / green
infrastructure proposals,
would help to assimilate the
barrier with its surroundings.
More aircraft approaching and
leaving Heathrow Airport
would be seen in the
immediate background due to
an increase in ATMs, and at
close proximity due to use of
the new, closer runway.
Preliminary conclusions drawn
at this stage are Moderate Adverse magnitude; Large Adverse significance.
It is expected that
views of the maturing
landscape / green

principal source of light emissions.
Lighting associated with the airfield is
anticipated to be predominantly
obscured by the intervening noise
mitigation buffer, however there would
be increased presence of lights on
aircraft approaching and leaving
Heathrow Airport in the immediate
background due to use of the new,

increase in ATMs. Sky glow from
Heathrow Airport, already present, is
also expected to increase. Overall,
there is not expected to be a readily
apparent change in the overall
balance of night-time visual
influences. Preliminary conclusions
drawn at this stage are Minor Adverse magnitude; Slight Adverse

Zone G02 Option 1, comprising the Immigration Removal Centre (IRC), has been introduced to the DCO Project at a
late stage, in response to stakeholder engagement, and therefore relevant viewpoint(s) have not been considered or
consulted upon yet. Preliminary assessment indicates that the principal visual receptors in relation to the IRC would
comprise residential areas off Hatton Road, Bedfont, and those south of the Duke of Northumberland’s River, Bedfont
and Feltham North. In views to the Zone G02 Option 1 site from residential areas off Hatton Road, the foreground is
formed by green spaces, comprising open fields, with a backdrop of mature existing vegetation and light industrial and
commercial development along Faggs Road, North Feltham, beyond. In views to the

Zone G02 Option 1 site from the residential areas south of the Duke of Northumberland’s River, the foreground is
largely defined by vegetation along the Duke of Northumberland’s River, which restricts views to the green spaces,
together with more distant commercial and industrial areas, beyond. It is expected that construction activities
associated with the IRC would constitute disruptive elements, resulting in adverse visual effects during construction of
the facility. On completion, the IRC would introduce built development within green space and against a well-vegetated
backdrop, also resulting in adverse effects, however these effects are expected to be ameliorated at design year by
maturing landscape / green infrastructure proposals at the periphery of the IRC and in the area surrounding the IRC.

15.12 Assessment of cumulative effects
The cumulative effects assessment (CEA) presented in this section reflects Stage
3 in the CEA process set out in Section 5.8 of Chapter 5.
The assessment of cumulative landscape and visual amenity effects is based on
professional judgement, taking into account the levels of significance identified in
the primary or ‘stand-alone’ assessment, and identifying whether effects could be
different when ‘other development’ are considered.
A CEA is only undertaken for those receptors that are likely to experience effects
greater than neutral in the primary assessment. This is because such effects are
unlikely to result in any discernible positive or negative effects on a receptor. It is
considered that they are extremely unlikely to result in a significant cumulative
effect, even if multiple effects of a similar significance are considered.
The following sections present the assessment of the cumulative effects of the
DCO Project and ‘other developments’ on landscape and visual amenity. Effects
are described for each phase of the DCO Project where relevant. It is expected
that an assessment of cumulative effects at c.2050 (‘opening year’ for the
purposes of landscape and visual amenity assessment) and c.2065 (‘design year’
for the purposes of landscape and visual amenity assessment) would be the
same, given the information available regarding ‘other developments’ and phasing
of ‘other developments’ relative to the DCO Project. As a result, only cumulative
effects at the design year are presented.
The ‘other developments’ to be considered in the CEA for the PEIR are those on
the ‘assessment list’ provided in Chapter 5, Section 5.8.
Only those developments in the assessment list that fall within the Landscape and
Visual Amenity ZOI, defined for the CEA, have the potential to result in cumulative
effects with the DCO Project. The Landscape and Visual Amenity ZOI is shown in
Chapter 5, Figure 5.1. All developments on the assessment list, with the
exception of O750 Land at Watersplash Farm, fall within the Landscape and
Visual Amenity ZOI.
The Chiltern Hills AONB is located outside the landscape and visual amenity study
area. Nonetheless, the effects of High Speed 2 (London – West Midlands),
together with airspace considerations relating to the DCO Project, have been
considered regarding the tranquillity aspect of the Chiltern Hills AONB landscape
(through which High Speed 2 passes), as is consistent with the approach set out in
Section 15.4.
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.198 © Heathrow Airport Limited 2019
For the PEIR, the following developments on the assessment list in Chapter 5, Section 15.7 have been brought forward for consideration in relation to the
landscape and visual amenity CEA:
O109 Land at Harmondsworth, Holloway Close
O591 Rectory Lane, Cranford Lane
O595 Stanwell Recycling, Stanwell Quarry
O596 Stanwell Recycling, Stanwell Quarry
O601 Queen Mary Reservoir and Land West of Queen Mary Reservoir
O608 Cemex Datchet Quarry, Land At Riding Court Farm
O609 Land East of Horton Road
O615 Southall Gas Works
O732 Queen Mary Reservoir and Land West of Queen Mary Reservoir
O745 Land at Milton Park Farm
O751 Slough Heat & Power Station
O810 M4 Junctions 3 to 12 Smart Motorway
O811 High Speed 2 (London - West Midlands)
O812 Western Rail Link to Heathrow
O813 Southampton to London Pipeline Project.
A2 T5+ (T5A)
A3 T5+ (T5B)
A4 T5+ (T5C)
A5 Perry Oaks Fuel Farm
It should be noted that any effects related to road-traffic noise considered within
the primary assessment in Section 13.10 is inherently cumulative and no
additional CEA associated with road traffic noise is required. This is because the
traffic model on which the noise assessment is based uses modelled traffic data
that has been adjusted to account for growth in future traffic flows. The modelling
takes account of employment and housing projections, future infrastructure
projects, and development in both Development Plans and in the planning
process.
Heathrow Expansion PRELIMINARY ENVIRONMENTAL INFORMATION REPORT: Chapter 15: Landscape and visual amenity
15.199 © Heathrow Airport Limited 2019
Nonetheless, the modelled traffic data has not been adjusted to account for
changes that may occur as a result of the O812 Western Rail Link to Heathrow
project. As such, potential cumulative effects associated with road traffic changes
as a result of this development, are not inherently included in the assessment in
Section 13.10. As set out in Section 17.11 in Chapter 17, major infrastructure
schemes not currently included for in the traffic model, such as the Western Rail to
Heathrow project, would reduce the use of and improve the operation of the
strategic road network around Heathrow. It is therefore considered that long-term
adverse cumulative effects are unlikely. In turn, long-term adverse cumulative
effects in relation to the tranquillity aspect of the landscape, are also unlikely.
Cumulative effects as a result of construction activities will be considered in the
assessment carried out for the ES.
Construction and interim ATM effects: c.2022-2050
Table 15.23 sets out the assessment of cumulative effects on relevant receptors
identified in Section 15.4.

The following developments have the potential to affect landscape/townscape character:
1. O109; O595; O596; O601; O608; O609; O732 and O745: These minerals or waste operations would
occur at or in the vicinity of the DCO Project. The operations would be comparable with construction
activities associated with the DCO Project. Where these activities would occur at or very close to the
DCO Project site, DCO Project construction activities (resulting in Large Adverse effects) are expected to
be the dominant factors such that reported assessment of effect categories would not change. Where a
development would be more distant from the DCO Project but would be present at close quarters in a
landscape that is local to such a development, the DCO Project components would form minor elements
within the backdrop therefore resulting in limited cumulative change
2. O591 Rectory Lane, Cranford Lane: This development would be constructed using an innovative sub-
surface process. A park would be created on the surface, which is expected to result in positive
landscape effects. As a result, this development together with the DCO Project are not expected to
generate adverse cumulative effects
3. O615 Southall Gas Works: This development would be sufficiently distant from the DCO Project to result
in limited cumulative change together with the DCO Project. Where this development would be present
at close quarters in the landscape, the DCO Project components would form distant elements therefore
resulting in limited cumulative change
4. O751 Slough Heat & Power Station: This development would be sufficiently distant from the DCO Project

would be present at close quarters in the landscape, the DCO Project components would form distant
elements therefore resulting in limited cumulative change 5. O810 M4 Junctions 3 to 12 Smart Motorway: This development would be almost complete at the time of
DCO Project construction activity and given the transport corridor is already present the development
would result in limited adverse cumulative change together with the DCO Project
6. O811 High Speed 2 (London – West Midlands): This development would be distant from the DCO
Project, resulting in limited cumulative change together with the DCO Project. In locations where High

within this part of the Chilterns landscape, such that tranquillity would not be affected
8. O812 Western Rail Link to Heathrow: Much of this development would be underground with discrete
areas of above ground construction activity likely to result in limited adverse cumulative change together
with the DCO Project
9. O813 Southampton to London Pipeline Project: Much of this development would be underground during
operation, however above ground construction activity would be prevalent across the pipeline site. This
construction activity would only interact with the DCO Project construction activity at the southern
extremity of the DCO Project site and is likely to result in limited cumulative change together with the
DCO Project
10. A2 to A5 Heathrow Airport Developments: These developments would occur within an immediate context
already defined by airport infrastructure and development, therefore there are not expected to be notable
cumulative changes together with the DCO Project.
There is likely to be a cumulative effect of the DCO Project together with these developments, due to the
construction phase of the DCO Project overlapping with the construction and operational phases of these
projects. However, preliminary conclusions drawn at this stage are that the cumulative effect would not change the DCO Project effects assessment categories reported in Section 15.10.

15.13 Consideration of additional environmental measures or compensation
No additional environmental measures are proposed to further reduce the
landscape and visual amenity effects that are identified in this PEIR. This is
because all relevant and implementable measures are proposed to be embedded
into the DCO Project design and are assessed in the chapter.
15.14 Next steps
Engagement with those identified in Section 15.3 will continue and will inform the
baseline, further development of environmental measures and assessment of
effects, as appropriate. Winter photography and night-time photography will be
undertaken to support the baseline, and visualisations of the DCO Project will be
prepared by the design team to support the assessment. The design and
assessment processes will continue to enable further development and
assessment of the DCO Project in respect of landscape and visual amenity.
