13 CLIMATE CHANGE Introduction
GL Hearn has been appointed to undertake a climate change assessment of the
Proposed Development, in accordance with the requirements of the EIA Regulations
and the Climate Change Act 2008.
The climate change assessment consists of two parts:
Impact of the Proposed Development on climate – the greenhouse gas (GHG)
emissions assessment considers the change in GHG emissions due to the proposed
development; and
Vulnerability of the Proposed Development to climate change – the Climate Change
Resilience assessment (CCRA) considers the resilience of the proposed
development in the context of projected future changes in climate variables.
GHG emissions during the construction and operation of the Proposed
Development are likely to impact on climate change.
The Proposed Development is also vulnerable to changes in extreme weather
events such as heat waves due to warmer temperatures, increase in rainfall and
wind strength and resilience to climate change of the Proposed Development have
also been assessed as part of this Chapter of the ES.
To take account of the potential impacts of future climate conditions to act in-
combination with the impacts of the Proposed Development on other environmental
receptors, the future projected climate conditions for the area were incorporated into
the future baseline conditions and considered for relevant EIA topics in their
assessment of likely significant effects. This ensures that environmental receptors
GL Hearn Page 605 of 677
that are vulnerable to impacts from both the Proposed Development and climate
factors are considered in the context of the changing climate. A summary of the in-
combination climate change impact (ICCI) assessment for each topic is presented
in this Chapter.
The chapter is supported by the following Appendices:
• Appendix 13.1: B9-GL2.25-Whole Life Carbon Emissions Assessment-Rev 1 • Appendix 13.2: MC-GL2.29-Whole Life Carbon Emissions Assessment-Rev 1 • Appendix 13.2: R&F-GL2.14-Whole Life Carbon Emissions Assessment-Rev 1
Legislation and Policy Context Legislation
The UK is no longer a member of the European Union. Some aspects of EU
legislation as it applied to the UK on 31st December 2020 are now a part of UK
domestic legislation, under the control of the UK’s Parliaments and Assemblies.
The European Union (Withdrawal) Act 2018 introduced "retained EU law" which
provides that EU-derived domestic legislation continues to have effect after 31st
December 2020.
International Kyoto Protocol (1997)
The Kyoto Protocol is an international treaty which extends the United Nations
Framework Convention on Climate Change (UNFCCC) and commits its parties by
setting internationally binding emission reduction targets. Under Article 4 of the
Kyoto Protocol, the EU created an Effort Sharing Regulation that requires the setting
of individual binding GHG emission reduction targets for each of its Member States.
GL Hearn Page 606 of 677
Paris Agreement (2015)
At the Conference of the Parties (COP) 21 an agreement, (the Paris Agreement),
was reached under the UNFCC and came into force in November 2016 and pledges
long-term temperature goals to keep the increase in global average temperature to
well below 2°C above pre-industrial levels and to pursue efforts to limit the increase
to 1.5°C. Additionally, the Agreement includes commitments, strengthening
resilience and reducing vulnerability to climate change. The guidelines for
implementing the Paris Agreement were adopted at the 24th Conference of the
Parties (COP24), in Katowice, Poland .
The UK Climate Change Act125 commits the UK to cut carbon emissions by 80% by
the year 2050. However, on 27 June 2019, the UK passed a more stringent net zero
emissions law to bring all greenhouse gas emissions to net zero by 2050.
The Climate Change Act 2008 requires that five-yearly Carbon Budgets are set and
not exceeded. It also established a requirement to undertake a climate change risk
assessment (CCRA) every five years and development of a programme for
adaptation action in response to the risks identified. Adaptation actions involve the
provision of better information, diversification of supply chain risks and building better
capacity to manage, share and transfer risk. There is an important role for new
technology and infrastructure. These actions fall mostly to business, but government
can support them by ensuring information and advice is available, especially for
smaller businesses, and by implementing stronger reporting requirements for
businesses and infrastructure providers.
The Government commissioned the completion of the National Climate Change Risk
Assessment126. The Climate Change Risk Assessment provides a useful basis for
assessing the likely future environment which EIAs need to consider and provides
information on the range of impacts likely to be experienced in a range of sectors.
125 United Kingdom Government (2008) Climate Change Act. 126 UK Climate Change Committee (June 2021) National Climate Change Risk Assessment
GL Hearn Page 608 of 677
implications for flood risk, coastal change, water supply, biodiversity and landscapes,
and the risk of overheating from rising temperatures. Developments should also
avoid increased vulnerability to the range of impacts arising from climate change and
should be planned for in ways that can help to reduce GHG emissions, in line with
the objectives and provisions of the Climate Change Act 2008.
Clean Growth Strategy (2017)
The UK Government published the Clean Growth Strategy, to support the UK in
meeting its legislated carbon budgets. The strategy includes a key policy to
accelerate the shift to low carbon transport, which primarily focuses on a transition
to low emission vehicles, investing in new technologies such as autonomous
vehicles and low carbon fuels, promoting cycling and walking and shifting freight
from road to rail.
London Plan (2021)
The London Plan128 outlines a number of policies in relation to reducing carbon
emissions and improving efficiency.
Policy GC6 states that:
• “developments must seek to improve energy efficiency and support the move towards a low carbon circular economy, contributing towards a low carbon circulate economy, contributing towards London becoming a zero-carbon city by 2050…”.
Policy SI 2 focuses on minimising GHG emissions from both the operational and
construction phases of development:
• “Major development should be net zero-carbon. This means reducing greenhouse gas emissions in operation and minimising both annual and peak energy demand” and “Development proposals referable to the Mayor should calculate whole life-cycle carbon emissions through a nationally recognised
128 Mayor of London (March 2021) The London Plan
GL Hearn Page 609 of 677
Whole Life-Cycle Carbon Assessment and demonstrate actions taken to reduce life-cycle carbon emissions.”
The London Plan also outlines a number of policies in relation to climate change
resilience.
Policy GC 6 states developments must:
• “ensure buildings and infrastructure are designed to adapt to a changing climate, making efficient use of water, reducing impacts from natural hazards like flooding and heatwaves, while mitigating and avoiding contributing to the urban heat island effect…”
In addition, Policy SI 4 states:
• “Major development proposals should demonstrate through an energy strategy how they will reduce the potential for internal overheating and reliance on air conditioning systems”
Barnet’s Local Plan (September 2012)
Policy CS13 of the currently adopted Local Plan129 states that:
“We will seek to minimise Barnet’s contribution to climate change and ensure that
through the efficient use of natural resources the borough develops in a way which
respects environmental limits and improves quality of life.
• We will promote the highest environmental standards for development and through our SPDs on Sustainable Design and Construction and Green Infrastructure we will continue working to deliver exemplary levels of sustainability throughout Barnet in order to mitigate and adapt to the effects of a changing climate.
• We will expect all development to be energy efficient and seek to minimise any wasted heat or power.
• In line with London Plan Policy 5.2 – Minimising Carbon Dioxide Emissions we will expect major development in accordance with the Mayor’s energy hierarchy to reduce carbon dioxide emissions beyond the 2010 Building Regulations.
• We will maximise opportunities for implementing new district-wide networks supplied by decentralised energy (including renewable generation) in partnership with key stakeholders in areas of major mixed use growth including town centres.
129 London Borough of Barnet (September 2012) Barnet’s Local Plan (Core Strategy) development Plan Document
GL Hearn Page 610 of 677
Where feasible we will expect all development to contribute to new and existing frameworks.
• We will support solutions that minimise or avoid harm to a heritage asset’s significance while delivering improved energy performance or generation.”
Barnet Draft Local Plan (June 2020)
LBB have also prepared a Draft Local Plan130 to cover the period 2021 to 2036.
Policy ECC01 – Mitigating Climate Change, follows the same lines as London Plan
policies and states:
“The Council will seek to minimise Barnet’s contribution to climate change and
ensure that through the efficient use of natural resources the Borough develops in a
way which respects environmental limits and improves quality of life. The Council
will…expect all development to be energy-efficient and seek to minimise any wasted
heat or power and meet the requirements of Policy CDH02.
All major development will be required to demonstrate, through an Energy Statement
accordance with Part L of the Building Regulations and London Plan polices SI2 and
SI3 including compliance with the Mayor’s net zero carbon targets.
For minor development efforts should be made to make the fullest contribution to
minimising carbon emissions and meet a carbon reduction target of at least 6%
beyond the latest Building Regulations and demonstrate how the Mayor’s Energy
Hierarchy has been used to achieve this.”
It goes on to states that:
“All schemes are encouraged to incorporate renewable energy initiatives into
development proposals, where feasible…Where the carbon targets for a
development cannot be fully achieved a contribution will be sought to a value
130 Barnet Draft Local Plan
GL Hearn Page 611 of 677
calculated using the latest nontraded price of carbon per tonne identified by the
Mayor of London…Developments are required to demonstrate how sustainable
design and construction methods are incorporated into the proposal to enable the
development to mitigate and adapt to climate change over its intended lifetime.”
Guidance and Best Practice
IEMA Environmental Impact Assessment Guide to Climate Change Resilience and Adaption (2020)
This guidance131 provides a framework for the effective consideration of climate
change resilience and adaptation in the EIA process. This publication is an essential
reference point and guidance for considering climate change resilience and
adaptation in EIA, for professionals coordinating EIA’s or supporting significant
assessments for climate change. It also draws from the relevant aspects of the EIA
Regulations.
IEMA Environmental Impact Assessment Guide to: Assessing Greenhouse Gas Emissions and Evaluating their Significance (2016)
This guidance132 sets out a number of different assessment methods for measuring
and quantifying greenhouse gas (GHG) emissions.
Whole Life-cycle Carbon Assessment Draft Guidance (2021)
The GLA have published draft guidance133 for undertaking whole life-cycle carbon
(WLC) assessments in line with Policy SI2 of the London Plan. The guidance
explains how to calculate WLC emissions that should be submitted to comply with
policy.
London Energy Transformation Initiative (LETI) (2020)
LETI provide guidance on how new buildings in the UK can meet climate change
targets both through embodied carbon during the construction phase and
operational carbon. LETI believe that in order for the UK to meet the net-zero targets

by 2050, all new buildings should operate at net-zero by 2030 and all buildings
should operate at net-zero by 2050. As such, their “Climate Emergency Design
Guide”134 and “Embodied Carbon Primer”135 provides measures on how to reduce
carbon emissions from both embodied carbon and operational carbon and also
provides targets that new buildings should meet in order to ensure that all new
buildings can operate at net zero carbon from 2030.
National Planning Practice Guidance on Climate Change
Online guidance published by the Ministry of Housing, Communities and Local
Government. This describes how to identify suitable mitigation and climate
adaptation measures to incorporate into the planning process. Stating “effective
spatial planning is an important part of a successful response to climate change as
it can influence the emission of greenhouse gases. Planning can also help increase
resilience to climate change impact through the location, mix and design of
development.”
Assessment Methodology and Significance Criteria
This section presents the methodology used to assess the potential effects of the
Proposed Development in relation to Climate Change

Development. CO2e refers to a common unit employed to compare the emissions
from various GHGs (methane, ozone, nitrous oxide etc.) based on their global-
warming potential, by converting the amounts of other gases to the equivalent
amount of CO2 with the same Global Warming Potential. The adoption of CO2e as
the common metric, rather than CO2, allows all GHGs to be included in the
assessment and contextualised against local and national targets.
The goal of the emissions quantification exercise is to calculate the emissions likely
to be generated or avoided by the Proposed Development. The purpose of this is to:
• Determine the magnitude of the Proposed development’s GHG emissions; • Enable comparison of the Proposed Development’s GHG emissions and the UK
carbon budget; and, • Enable identification of GHG emissions hot spots to inform identification and
prioritisation of mitigation measures.
The GHG assessment has taken a 60 year appraisal period to measure the
operational emissions of the Proposed Development. This is in keeping with the GLA
guidance , which states the reference study period for the Proposed Development
should be 60years.
In order to assess a worst case impact, the baseline existing GHG emissions have
not been calculated and a baseline of zero emissions has been considered.
The GHG assessment quantifies and reports the GHG emissions anticipated to be
generated or avoided by the Proposed Development in the form of a ‘carbon
footprint’. The carbon footprint is reported in tCO2e.
In order to adequately capture direct and indirect emissions associated with the
proposed development, a Whole Lifeycle approach has been adopted.
Whole Life-cycle Carbon (WLC)
GL Hearn Page 616 of 677
Recycling
GHG emissions from the Proposed Development are quantified by using ‘activity
data’ (such as material quantities, energy consumption and transport kilometres
travelled) to quantify GHG emissions through the use of emissions conversion
factors.
Construction material types and quantities have been obtained from the Cost Plans
for each of the three sites and can be seen in Appendix x and x. Operational data
has been obtained from the Energy & Sustainability statements that have been
prepared to accompany the respective planning applications for these sites.
Vulnerability to Climate Change
Climate change can lead to more frequent and extreme weather events, which can
affect schemes in the UK. This can include higher temperatures and increased
flooding and storm risk.
Climate change projection information published by the Met Office, known as UK
Climate Projections (UKCP18)136, released in November 2018, are now the most up
to date climate change projections available.
In line with IEMA Guidance, the assessment of the vulnerability to climate change
assessment uses the ‘worst case scenario’ of future weather projections
(Representative Concentration Pathway (RCP) 8.5 scenarios). This worst-case
scenario assumes a ‘business-as-usual’ pathway leading, in the long term, to high
energy demand and GHG emissions in absence of climate change policies.
136 Met Office, (2018) UK Climate Projections (UKCP18)
GL Hearn Page 618 of 677
Therefore, the GHG assessment contextualises the emissions with national, regional
and local carbon budgets in order to develop appropriate mitigation measures. The
UK carbon budgets are set out in Table 13.1.
The Department of Energy and Climate Change (DECC) and the Department for
Business, Energy and Industrial Strategy (BEIS) agree that emission source
contributions of less than 1% would not be significant to the overall impact. A
development with emissions of less than 1% of the relevant five year carbon budget
would, therefore, be minimal in its contribution to the wider GHG emissions.
Therefore, it is considered that:
• Emissions that are less than 1% of the relevant carbon budget would have a Low Impact, which would be classed as a Minor Adverse and Not Significant effect; and
• Emissions that are more than 1% of the relevant carbon budget would have a High impact, which would be classed as a Major Adverse and Significant effect.
In relation to B6 & B7 – energy use, if the Energy Strategy does not achieve net zero
carbon then it is considered that there are Significant effects and offsetting will be
required to offset the additional emissions to reduce the impacts to Not Significant.
Limitations and Assumptions
The GHG emissions assessment has been based on the information available at the
time of assessment. The materials and quantities used in the assessment are
included in the Cost Plans.
The changes in weather patterns as a result of climate change has used the UKCP18
climate projections, however, there is uncertainty associated with these projections.
The worst-case scenario (RCP 8.5) has been used to deliver a robust assessment.

Error! Reference source not found. shows that the Proposed Development
Emissions are 0.005% of the 6th Carbon Budget. This equates to a Low impact, and
thus a Minor Adverse and Not Significant Effect.
Vulnerability to Climate Change
Potential long-term changes to weather patterns have been considered within the
design of the Scheme.
Overheating analysis has been undertaken by the Energy Consultants for the
Proposed Development to determine the potential for overheating in the future
because of climate change impacts. Three scenarios have been considered: 2020,
2050 and 2080. The Energy Consultants have stated that:
• In 2020, no overheating was predicted. In 2050, the analysis failed, and overheating impacts were predicted. As a result, the energy strategy has included the use of Air Source Heat Pumps (ASHP) which can be switched to cooling during warmer periods, providing additional cooling and thus resulting in passes in 2050.
• In 2080, the ASHP did not provide enough cooling to result in a pass. However, it is considered that during the 60 year period between the present and 2080, all services would have to be replaced at least once, therefore, there is the opportunity to re-asses the potential climate change impacts and provide additional cooling fans during services replacements if considered necessary at the time.
In relation to potential future flooding risks, Flood Risks Assessment have been
prepared by Capita which state that the Proposed Development is at a very low risk
of flooding and the impact as a result of the Proposed Development is considered to
be negligible. In order to allow for sufficient drainage, a surface water drainage
GL Hearn Page 626 of 677
provide a beneficial impact, therefore there is very little mitigation proposed. Mitigation that is proposed takes the form of ensuring school capacity and health services are monitored. It is not considered that climate events will impact the efficacy of such mitigation.
Transport and Access
Changes in weather are unlikely to impact on the proposed mitigation in relation to traffic and transport. The Proposed Development itself is unlikely to significantly change traffic flows on the local road network, therefore proposed mitigation is in the form of providing additional parking spaces to replace any lost due to the scheme. It is not considered that climate impacts will have a significant impact on this.
Ground Conditions, Soils and Contamination
Climate change will have no impact on the proposed mitigation measures in relation to contaminated land. Groundwater levels could lower in unusually dry summers but this would be beneficial in terms of reduced leaching where made ground extends below the current water table.
Built Heritage, Townscape and Visual Impact
Climate change is unlikely to have any significant impacts on built heritage, townscape and visual impact. Minimal mitigation is proposed with the main concern surrounding increased dust, vibration and noise levels during construction. However, these are mainly within the site and climate change is unlikely to provide a requirement for any additional mitigation to reduce increased dust levels as a result of dryer warmer summers for example.
Based upon this analysis, there will be no residual in-combination climate change
impacts associated with vulnerability to climate change.
Mitigation Measures
The WLC assessments indicate that the ideal carbon emission benchmarks are
exceeded for RFC and MC individually, and the three schemes when considered
overall. The largest contributors to carbon emissions overall are from the concrete
stair structures.
It is recommended that materials from the demolition phases of the Proposed
Development should be recycled and re-used where possible to reduce raw
materials production and transport emissions. A low carbon concrete should be
considered where possible, especially since the concrete stair structures are a high
contributor. Using a lower carbon concrete where practicable will help in reducing
carbon emissions.
GL Hearn Page 627 of 677
The Energy Strategies for the corresponding sites outlines the estimated carbon
offset amounts required in order to meet Net-Zero carbon targets:
• For B9 - £16,265. • For RFC - £354,130. • For MC - £111,088.
Residual Impacts and Monitoring
The residual impacts arising from the Proposed Development are summarised in
Table 13.16 above.
GL Hearn Page 629 of 677
Operational Effects
In terms of the operational phase, it is the responsibility of each development to meet
the net zero target requirements. Given the Proposed Development is meeting the
net zero targets through reduction in payments of offsetting payments, it is not
considered that cumulative developments will impact this. It is not considered that
the developments will change the climate change resilience baseline and future
weather patterns and will not impact overheating and floor risk for example.
Therefore, no significant cumulative impacts in relation to climate during the
operational phase are anticipated
GL Hearn Page 630 of 677
14 REDISUAL IMPACTS, MITIGATION MEASURES AND CUMULATIVE EFFECTS
The following chapter provides a summary of the anticipated residual impacts,
mitigation measures and the potential in-combination and/or cumulative effects for
each technical topic within the ES.
Summary of Mitigation and Residual Effects
This chapter of the ES summarises the residual impacts of the EIA of the Proposed
Development. Tables 14.2 and 14.3 below report the possible environmental effects
associated with the Proposed Development, proposed mitigation where appropriate,
and the identification of residual effects.
Residual impacts are defined as those impacts which remain following the
implementation of identified mitigation measures.
The formulation of the Proposed Development has been an iterative process
undertaken in parallel with the assessment of environmental effects. As a
consequence, some measures to mitigate potentially significant negative effects
have been incorporated into the design of the Proposed Development in order to
avoid, reduce, or offset such effects.
However, where it has not been possible to incorporate mitigation measures into the
iterative design process, mitigation may be achieved by one of the following means:
• Mitigation through controls on construction activities; or
• Mitigation to be applied through on-going management and monitoring once the
Proposed Development commences; or
• During the operation of the Proposed Development.

Summary of Residual Effects
A comprehensive and robust assessment of the potential impacts of the construction
and operational phases of the Proposed Development has been undertaken. Further
to this, a range of appropriate mitigation measures have been proposed to minimise
any likely significant effects.
As summarised in the Summary of Construction and Operational Impacts set out in
Table 14.2 and Table 14.3 above, the majority of impacts on the environment during
both the construction and operational phases of the Proposed Development are not
significant, being identified as being, either negligible, no change, minor adverse, or
minor beneficial.
After the implementation of a range of mitigation measures, significant beneficial
residual effects during the construction phase are as follows:
• Socio-Economics: specifically in relation to construction related employment and GVA (Moderate Beneficial)
No significant adverse effects are anticipated during the construction phase of the
Proposed Development following the implementation of suitable mitigation
measures.
A number of environmental mitigation measures are proposed within the ES and will
be implemented during the construction phase. These include specific measures for
the Proposed Development and the individual sites, as well as more general
measures appropriate for urban regeneration projects in accordance with best
practice guidance. The Applicant will develop and implement a CEMP, incorporating
commitments within this ES and setting out how LBB requirements will be met. The
CEMP will be prepared prior to the commencement of any on-site works and will
identify any mitigation measures that will be implemented to reduce the potential for
significant adverse effects. Assuming appropriate implementation of the CEMP,
GL Hearn Page 654 of 677
construction of the Proposed Development is not considered likely to result in any
significant, long-term adverse effects.
After the implementation of mitigation measures, significant beneficial residual
effects during the operational phase are as follows:
• Socio Economics, specifically in relation to:
o Safeguarded employment (moderate beneficial)
o Expenditure (moderate beneficial)
o Housing Provision (Major beneficial)
o Housing affordability (moderate beneficial)
o Community facilities (moderate beneficial)
o Crime (moderate beneficial – on the assumption the safer neighbourhood unit
is provided)
o Education (major beneficial)
• Built Heritage, Townscape and Visual Impact, specifically in relation to:
o Heritage Asset - Hendon Church End Conservation Area (moderate beneficial)
o Visual Receptor – Junction of Church End and Church Road (minor/moderate
beneficial)
o Visual Receptor Church End (1) (moderate beneficial)
After the implementation of mitigation measures it is considered that there will be no
significant adverse residual effects during the operational phase.
Whilst it is likely that some adverse effects may be experienced during the
construction phase of the Proposed Development, these will be temporary in nature
and mitigated as far as possible by the CEMP and best practice guidance.
GL Hearn Page 655 of 677
Once the Proposed Development is operational, the positive impacts associated with
bringing this development forward are considered to far outweigh these adverse
effects.
Cumulative Effects
In addition to the assessments already undertaken in relation to environmental topics,
the EIA Regulations143 require an ES to consider ‘cumulative effects’. These are
defined as effects which result from incremental changes caused by other past,
present, or reasonably foreseeable actions together (i.e. Cumulatively) with the
Proposed Development.
For the cumulative assessment two types of effect have been considered:
• Type 1: The combined effect of individual effects on a single receptor (defined as ‘effect interactions’); and
• Type 2: The combined effects of nearby development schemes which are either consented or under construction which may, on an individual basis, not be significant but, cumulatively, have a likely significant effect (defined as ‘cumulative effects’). The schemes considered within this assessment may vary according to topic, however, a comprehensive list is provided in Chapter 2: EIA Methodology of this ES.
Effect Interactions (Type 1 Effects)
There is no established EIA methodology for assessing and quantifying effect
interactions that lead to combined effects on sensitive receptors. The European
Commission (EC) has produced guidelines for assessing these Type 1 Effects144,
however these “are not intended to be formal or prescriptive but are designed to
assist EIA practitioners in developing an approach which is appropriate to a project…”
These have been reviewed by GL Hearn and used to develop the approach to
assessment of effect interactions presented in this ES.
Whilst not necessarily considered significant individually, several effects on one
receptor or receptor group could interact or combine to produce a significant overall
143 The Town and Country Planning (Environmental Impact Assessment) Regulations 2017 144 European Commission (EC) (1999): Guidelines for the Assessment of Indirect and Cumulative Impacts as well as impact interactions. Available at: http://ec.europa.eu/environment/archives/eia/eia-studies-and-reports/pdf/guidel.pdf
GL Hearn Page 656 of 677
effect. For the purposes of the assessment only adverse or beneficial effects
classified as minor, moderate or major have been considered in the effect
interactions assessment.
Table 14.4 and Table 14.5 present a summary of the residual effects on sensitive
receptors which have been scoped into the effect interactions assessment,
Table 14.4 and Table14.5 set out that no significant effect interactions are
anticipated to occur during either the construction or operational phases of the
Proposed Development.

Cumulative Effects (Type 2 Effects) Socio-Economics
Cumulative effects in relation to socio-economic effects are discussed in Chapter 11
of this ES. This assessment identifies whether effects from several developments,
which individually may not be significant, could, when considered together, cause
significant cumulative effects requiring mitigation.
Construction
In terms of the construction phase, it is recognised that adverse cumulative socio-
economic effects could arise if all of the developments were to come forward at the
same time. This could result in socio-economic effects including the availability of
labour being constrained and/or potential disturbance to local community facilities
and amenities. However, these projects are at different stages of the development
process, have varying lead in times and are of a variety of scales. Similarly, the
majority of sites are considered too far from the Proposed Development to give rise
to cumulative effects resulting from the physical works involved (e.g. disrupting
community facilities). It is therefore concluded that overall there may be a temporary
minor adverse cumulative socio-economic effect. Particular sites of note during
construction are set out below:
• Fosters Estate London (Planning Reference: 19/2517/FUL): This is a major
redevelopment consisting of multiple phases. Timeframes of construction
could potentially clash with the Proposed Development, however distance
from the site is substantial so construction impact on the surrounding
community is considered to be negligible.
• Westhorpe Gardens and Mill Grove (Planning Reference: 18/7495/FUL): This
is a substantial development but considered to have negligible cumulative
GL Hearn Page 667 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
impact on the socio economic landscape alongside the Proposed
Development due to distance from the sites.
• Hendon Post Office (Planning Reference: 20/5081/FUL): This is a relatively
small-scale development removed from the Proposed Development.
However, shared access road could create some disruption to local service
accessibility, potentially creating a temporary minor adverse impact on the
sociocultural environment of Hendon during construction. These effects are
expected to be minimal.
Operational
The majority of developments identified in Chapter 2 propose residential uses and
therefore will create additional demand on social infrastructure within the
surrounding area. As part of the planning assessment for these developments, it is
understood that, where appropriate, they will provide social and / or community
infrastructure to meet the demands they generate and wider needs across the Local
Impact Area.
LBB adopted its Community Infrastructure Levy (CIL) Charging Schedule in May
2013. This is in the process of being updated, with LBB submitting its Draft Charging
Schedule on 12 August 2021 to the Planning Inspectorate to be examined.
CIL contributions ensure that development proposals provide an appropriate
payment for funding of current and future infrastructure arrangements. On this basis
it is considered that the magnitude of any adverse effects arising from the increased
demand for social and community infrastructure will be negligible. Although the
anticipated cumulative socio-economic effect is considered to be negligible once the
Proposed Development is completed and operational, the following sites were
GL Hearn Page 668 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
identified with the need for school capacity to be monitored due to their size and
residential nature:
• Fosters Estate London (Planning Reference: 19/2517/FUL).
• Westhorpe Gardens and Mill Grove (Planning Reference: 18/7495/FUL)
• Raffles House, 67 Brampton Grove (Planning Reference: 20/5179/PNV)
Air Quality
Cumulative effects in relation to air quality are discussed in detail within Chapter 7
of this ES. The potential cumulative effects of the Proposed Development combined
with other development schemes in the local area (set out in Chapter 2) have been
thoroughly assessed.
Construction
In terms of the construction phase, it is recognised that adverse cumulative air quality
and dust effects could arise if all of the developments were to all come forward at
the same time. However, these projects are at different stages of the development
process, have varying lead-in times and are expected to come forward on a phased
basis thus reducing traffic impacts and dust nuisance from demolition and
construction activities.
In line with IAQM guidance, it is recommended that liaison should be undertaken
with any sites within 500m of the site boundary of the Proposed Development in
order to potentially reduce impacts through coordinating deliveries and increasing
dust inspections. It is considered through the effective implementation of mitigation
that any cumulative impacts will be negligible and not significant.
Operational
GL Hearn Page 669 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
In terms of the operation of the Proposed Development, it is recognised that vehicle
emissions from other developments may increase on roads associated with
Proposed Development traffic. However, given that the net change in vehicle flows
is below the IAQM criteria for assessments and is therefore negligible, it is unlikely
that any cumulative impacts as a result of traffic from other developments will result
in any significant impacts.
Noise
Cumulative effects in relation to noise and vibration are discussed in detailed within
Chapter 8 of this ES. The potential cumulative effects of the Proposed Development
combined with other development schemes in the local area (set out in Chapter 2)
have been thoroughly assessed.
Construction
Three of the sites set out in Chapter 2, have been identified as potentially giving rise
to significant cumulative adverse construction noise and vibration effects. For all
other sites it is considered unlikely. The three sites are: Fuller Street Car Park (to
the east of MC site), Scout Hut (Planning Application Reference: 20/4902/FUL) (to
the west of MC site), and 3-3A Burroughs Parade (Planning Application Ref:
21/3396/FUL). However, the 3-3A Burroughs Parade site falls within the red line
boundary of the Proposed Development and it is therefore highly unlikely that both
schemes would proceed together.
Fuller Street Car Park is located at Fuller Street approximately 30 metres to the east
of Meritage Centre red line boundary. Between the proposed Meritage Centre Block
2 and Fuller Street Car Park sit the dwellings 31 to 37 (odd numbers) Fuller Street.
Fuller Street, is expected to be demolished and constructed at the same time as the
Meritage Centre Block 2 is constructed and the current building at the place of
Meritage Centre Block 4 is demolished.
GL Hearn Page 670 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
Meritage Centre Block 2 works are more substantial than the works at Fuller Street
Car Park and are likely to be predominant in the surrounding area.
Housing at Sunninfields Road will be affected by concurrent works at Meritage
Centre Block 2 and at Fuller Street Car Park. These effects are expected to range
between adverse effects and significant adverse effects and will need to be taken
into account in the definition of the mitigation and monitoring of the Meritage Centre
works.
Noise monitoring is also proposed at housing at Sunningfields for the concurrent
effects of the construction of Meritage Centre Block 2 and Fuller Street Car Park.
Scout Hut is located 30 metres to the west of Meritage Centre red line boundary. If
the demolition and construction at Scout Hut was concurrent with the construction
works at Meritage Centre Blocks 1 or 2, these could concurrently affect the dwellings
located between Scout Hut and Meritage Centre, primarily the dwelling at Rose
Cottage. Works at Meritage Centre to occur at the same time as Scout Hut should
be carefully planned and if necessary noise monitoring should be considered.
In consideration of the potential for significant cumulative effects arising, mitigation
measures are identified, including:
• Use of Best Practicable Means
• Follow the Construction Logistics Plan
• Prepare and follow Construction Environmental Management Plan
• Utilise the Considerate Constructors Scheme
• Undertake additional noise monitoring at Sunning Fields Road and Rose
Cottage.
GL Hearn Page 671 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
It is considered that through the implementation of mitigation, that the residual
cumulative impact would not lead to significant effects.
Operational
No adverse effects were identified when the Proposed Development is operational
and therefore no cumulative effects are anticipated.
Transport and Access
Cumulative effects in relation to transport and access effects are discussed in
Chapter 9 of this ES. This assessment identifies whether effects from several
developments (set out in Chapter 2), which individually may not be significant, could,
when considered together, cause significant cumulative effects in relation to
transport and accessibility requiring mitigation.
Construction
In terms of the construction phase, it is recognised that adverse cumulative transport
and access effects could arise if all of the developments were to all come forward at
the same time. However, these projects are at different stages of the development
process, have varying lead-in times and are expected to come forward on a phased
basis thus reducing traffic impacts from demolition and construction activities.
The proximity of most sites mean that cumulative effects are unlikely to arise. It is
assumed that these proposals have, or will produce, Construction Environmental
Management Plans and, where appropriate, Construction Logistics Plans which will
mitigate any adverse effects.
GL Hearn Page 672 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
Operational
In terms of the operation of the Proposed Development, it is recognised that other
developments may increase trip rates by vehicle, public transport, pedestrians and
cycles and therefore give rise to cumulative effects in regard to Transport and
Access. As only negligible effects were identified when the Proposed Development
is operational, when it is considered together with the potential operational effects of
the cumulative schemes it is not anticipated to give rise to significant cumulative
effects. As part of the planning requirements for the cumulative schemes they too
will have to consider the effects of their proposals and mitigate them, through Travel
Plans etc.
Ground Conditions
Cumulative effects in relation to ground conditions, soils and contamination are
discussed in detail in Chapter 10 of this ES. The potential cumulative effects of the
Proposed Development combined with other development schemes in the local area
(set out in Chapter 2) have been thoroughly assessed.
Construction
Given the urban setting of the site and the prevalence of concealment of the geology
and geomorphological features, current and future projects in the area are unlikely
to be of a scale and nature that would significantly affect the geology and soils of the
area. Having reviewed the available information, any cumulative effects on the
geology and soils are considered to be low. This assessment is based on the type
of underlying geology, ALC assessments, current land uses, known contamination
sources and in some cases distance from the Proposed Development and size of
the proposals. In addition, the aquifers within the superficial deposits are unlikely to
be connected over large distances due to their distribution or being interbedded with
strata of low permeability so any hydrogeological connectivity is likely low.
GL Hearn Page 673 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
The assessment has considered the likely significant effects of the Proposed
Development both collectively and as a single project and have concluded that the
finding of no significant residual effects continues to apply and any cumulative effects
on the geology and soils are considered to be low.
Operational
Only negligible adverse effects were identified once the Proposed Development is
operational and when considered together with the potential operational effects of
the cumulative schemes are not anticipated to give rise to significant cumulative
effects.
Archaeology
Cumulative effects in relation to archaeology (buried heritage) assets are discussed
in detail within Chapter 11 Archaeology of this ES.
Construction
As with the Proposed Development, below ground demolition and construction
activities associated with the other development schemes set out in Chapter 2 has
the potential to negatively impact any below ground archaeological remains that may
be present.
It is anticipated that any planning approvals for the other development schemes will
have been made in consultation with the relevant stakeholders, in accordance with
national, regional and local planning policy guidelines. It is assumed that buried
archaeological remains would be a material consideration and that the provision for
archaeological assessment, investigation, mitigation and recording will be secured
where necessary.
GL Hearn Page 674 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
The sites identified in Chapter 2 have been assessed with reference to the
archaeological baseline data and the potential of any shared resources and
receptors which may experience cumulative effects has been considered.
Archaeological deposits and their relative survival are unique to each property on
the Hendon Plateau and in the case of all the sites addressed archaeological impacts
have either been mitigated, are in the process of being mitigated or will be mitigated
in the future. Consequently, the cumulative effects of the sites set out in Chapter 2
have been assessed and have been found not to lead to incremental changes that
would result in a finding of significant cumulative effects.
Operation
Only negligible impacts on sub-surface archaeological remains have been identified
once the Proposed Development is complete and operational, and therefore no
cumulative effects are anticipated.
Built Environment, Townscape and Visual Impact
Cumulative effects in relation to townscape, visual impacts, built heritage assets are
discussed in detail within Chapter 12: Built Environment, Townscape and Visual Impact of this ES.
Construction
The cumulative context as set out in Chapter 2 is not considered to change the
assessment and construction effects on any view which has been assessed during
the construction phase. This would remain Negligible Adverse and would be direct,
short-term, temporary effect.
Operational
GL Hearn Page 675 of 677 Z:\J041302 - FBC Fennella House, Hendon\14. Planning Submission - 2021\ENVIRONMENTAL STATEMENT\Volume II - Environmental Statement\Volume II Environmental Statement.docx
Once operational it is similarly considered that there will not be any cumulative views
impacts arising from the schemes set out in Chapter 2, including the four sites that
have been scoped out of the ES. In the case of the Quinta Club and Linear Woodland
landscape improvements, these are sufficiently distant from the identified views that
no cumulative impacts arise due to the lack of intervisibility.
The remaining cumulative schemes do not have any impact within any of the views
identified for assessment.
Climate Change
Cumulative effects in relation to Climate Change are discussed in detail within
Chapter 13: Climate Change of this ES.
Construction
In terms of the construction phase, it is recognised that each of the developments
will have carbon emissions associated with them. Given the scale and size of the
developments, it is unlikely that the cumulative impacts will result in a significant
impact in relation to the UK meeting its relevant carbon targets. It is not considered
that the developments will change the climate change resilience baseline and future
weather patterns. Therefore, no significant cumulative impacts in relation to climate
during the construction phase are anticipated.
Operational
In terms of the construction phase, it is recognised that each of the developments
will have carbon emissions associated with them. Given the scale and size of the

that the developments will change the climate change resilience baseline and future
weather patterns. Therefore, no significant cumulative impacts in relation to climate
during the construction phase are anticipated.
