1. Introduction

1.1.1. This Sustainability Statement forms part of the planning application for the South Bristol Link (SBL) scheme. The SBL scheme is one of three rapid transit routes that together create a Rapid Transit network across the City of Bristol, linking key employment, housing and leisure areas. The three rapid transit routes are:

Ashton Vale to Temple Meads and Bristol City centre (AVTM);

North Fringe to Hengrove (NFH); and

SBL.

1.1.2. The SBL scheme will facilitate regeneration and growth in South Bristol, whilst reducing congestion on surrounding roads and improve accessibility from South Bristol to the city centre and to the strategic transport network, including Bristol Airport.

1.1.3. This Statement has been prepared by Atkins Ltd on behalf of Bristol City Council (BCC) and North Somerset Council (NSC) the promoters of the SBL scheme. This report should be read in conjunction with other documentation that forms part of the planning application, including the Environmental Statement (ES) and Design and Access Statement (DAS).

1.1.4. The purpose of this Sustainability Statement is to ensure and demonstrate that sustainable development principles have been considered and incorporated into the planning and design process and to provide an indication of how they would be implemented in subsequent stages of construction and operation of the scheme. The Sustainability Statement identifies relevant sustainability considerations and uses these for setting out how sustainability has been or will be addressed.

1.1.5. This report is structured as follows:

Section 2 sets the policy context and explains how the sustainability topics and

considerations have been derived from a review of policy documents.

Section 3 details findings for each sustainability topic; and

Section 4 sets out conclusions.

1.2. The South Bristol Link scheme

1.2.1. The project falls within the administrative boundaries of both NSC and BCC. The proposed SBL will provide a 4.5km transport link between the A370 Long Ashton bypass within North Somerset and Hengrove Park within the Hartcliffe area of South Bristol. This will incorporate new and upgraded highway between the A370, the A38 and the Hartcliffe (Cater Road) roundabout, including a continuous shared cycleway and footway along the route corridor.

1.3. Policy Context and Considerations for each Sustainability Topic

Introduction

1.3.1. The SBL scheme is part of the wider Rapid Transit network. A sustainability framework has been developed for the assessment of the scheme to ensure a consistent approach in the production of a similar sustainability statement that is being prepared in support of the planning application for the NFH scheme.

1.3.2. The concept of sustainable development is central to the planning system. International and national bodies have set out broad principles of sustainable development. Resolution 42/187 of the United Nations General Assembly (1987) defined sustainable development as meeting the needs of the present without compromising the ability of future generations to meet their own needs. The 2005 UK Sustainable Development Strategy Securing the Future set out five ‘guiding principles’ of sustainable development:

living within the planet’s environmental limits;

ensuring a strong, healthy and just society;

achieving a sustainable economy;

South Bristol Link


10

promoting good governance;

and using sound science responsibly.

1.3.3. The SBL scheme crosses the boundaries of both Bristol City and North Somerset Councils so the following national and local documents have been identified because they set the common sustainability requirements for both schemes:

National Planning Policy Framework, 2012

The Climate Change Act, 2008

Bristol City Council Core Strategy, 2011

North Somerset Council Core Strategy, 2012

Bristol City Council Sustainable Building and Design Construction SPD, 2006

Bristol City Council Climate Change and Sustainability Practice Note, 2011

National Policy Context – National Planning Policy Framework, 2012

1.3.4. The National Planning Policy Framework (NPPF) recognises that there are three dimensions to sustainable development: economic, social and environmental. These dimensions give rise to the need for the planning system to perform a number of roles:

an economic role – contributing to building a strong, responsive and competitive economy,

by ensuring that sufficient land of the right type is available in the right places and at the right

time to support growth and innovation; and by identifying and coordinating development

requirements, including the provision of infrastructure;

a social role – supporting strong, vibrant and healthy communities, by providing the supply of

housing required to meet the needs of present and future generations; and by creating a

high quality built environment, with accessible local services that reflect the community’s

needs and support its health, social and cultural well-being; and

an environmental role – contributing to protecting and enhancing our natural, built and

historic environment; and, as part of this, helping to improve biodiversity, use natural

resources prudently, minimise waste and pollution, and mitigate and adapt to climate change

including moving to a low carbon economy.

1.3.5. The pursuit of sustainable development encompasses improvements in the quality of people’s life and the built, natural and historic environment, including the following:

making it easier for jobs to be created in cities, towns and villages;

moving from a net loss of bio-diversity to achieving net gains for nature;

replacing poor design with better design;

improving the conditions in which people live, work, travel and take leisure; and

widening the choice of high quality homes.

1.3.6. The NPPF sets out 12 core planning principles and 13 policies. Those most relevant to the SBL are:

proactive planning, support sustainable economic development, delivering the homes,

businesses, industrial units and infrastructure;

always seek to secure high quality design and a good standard of amenity;

support the transition to a low carbon future in a changing climate and with a diminishing

natural resource base;

contribute to conserving and enhancing the natural environment and reducing pollution, with

land of lesser environmental value being preferred for allocation;

promote growth patterns that tie in with opportunities for sustainable transport, e.g. public

transport, walking and cycling; and

aim to improve health, social and cultural wellbeing for all.

1.3.7. The NPPF policies provide the Government’s view of what sustainable development in England means in practice for the planning system. The list of policies is provided below with more details set out for Policy 4 (Promoting sustainable transport) as the most relevant one for the scheme:

South Bristol Link


11

Policy 1 – Building a strong, competitive economy

Policy 2 – Ensuring the vitality of town centres

Policy 3 – Supporting a prosperous rural economy

Policy 4 – Promoting sustainable transport

Policy 5 – Supporting high quality communications infrastructure

Policy 6 – Delivering a wide choice of high quality homes

Policy 7 – Requiring good design

Policy 8 – Promoting healthy communities

Policy 9 – Protecting Green Belt land

Policy 10 – Meeting the challenge of climate change, flooding and coastal change

Policy 11 – Conserving and enhancing the natural environment

Policy 12 – Conserving and enhancing the historic environment

Policy 13 – Facilitating the sustainable use of minerals

NPPF Policy 4 – Promoting sustainable transport

1.3.8. This policy states that ‘transport policies have an important role to play in facilitating sustainable development but also in contributing to wider sustainability and health objectives’. It is recognised that sustainable transport solutions may vary from place to place, however, the overall aim should be to reduce greenhouse gas emissions and congestion.

1.3.9. Local authorities should work with neighbouring authorities and transport providers to develop strategies for the provision of viable infrastructure. All developments that generate significant amounts of movement should be supported by a Transport Statement or Transport Assessment. The following should inform the preparation of plans and decision-making:

the opportunities for sustainable transport modes have been taken up depending on the

nature and location of the site, to reduce the need for major transport infrastructure;

safe and suitable access to the site can be achieved for all people; and

improvements can be undertaken within the transport network that cost effectively limit the

significant impacts of the development. Development should only be prevented or refused on

transport grounds where the residual cumulative impacts of development are severe.

The Climate Change Act 2008

1.3.10. The Climate Change Act 2008 makes the UK the first country in the world to have a legally binding long-term framework to cut carbon emissions. It also creates a framework for establishing the UK's ability to adapt to climate change. Two key aims of the Act are to:

improve carbon management, helping the transition towards a low-carbon economy in the

UK; and

demonstrate UK leadership internationally.

1.3.11. The Act sets out a legally binding target of at least an 80% cut in greenhouse gas emissions by 2050, to be achieved through action in the UK and abroad; and a reduction in emissions of at least 34% by 2020. Both these targets are set against a 1990 baseline.

Local Policy Context

Bristol City Council Core Strategy, June 2011

1.3.12. BCC’s Core Strategy guides development and growth and sets out the key elements of the planning framework for Bristol up till 2026 and beyond. There are several relevant policies in respect of sustainability that will apply to the SBL scheme, the key aspects of each relevant policy are stated below:

1.3.13. BCS9: Green infrastructure – The integrity and connectivity of the strategic green infrastructure network will be maintained, protected and enhanced. Opportunities to extend the coverage and connectivity of the existing strategic green infrastructure network should be taken. Individual

South Bristol Link


12

green assets should be retained wherever possible and integrated into new development. Loss of green infrastructure will only be acceptable where it is allowed for as part of an adopted Development Plan Document or is necessary, on balance, to achieve the policy aims of the Core Strategy. Appropriate mitigation of the lost green infrastructure assets will be required.

1.3.14. BCS10: Transport and Access Improvement – The council will support the delivery of significant improvements to transport infrastructure to provide an integrated transport system, which improves accessibility within Bristol and supports the proposed levels of development. This includes, amongst others, the delivery of rapid transit routes (Ashton Vale to Emerson’s Green and Hengrove to the North Fringe, all via the city centre) and South Bristol Link.

1.3.15. BCS13: Climate Change -Development should contribute to both mitigating and adapting to climate change, and to meeting targets to reduce carbon dioxide emissions. Development should mitigate climate change through measures including:

High standards of energy efficiency […].

The use of decentralised, renewable and low-carbon energy supply systems.

Patterns of development which encourage walking, cycling and the use of public transport

instead of journeys by private car.

Development should adapt to climate change through measures including:

Site layouts and approaches to design and construction which provide resilience to climate

change.

Measures to conserve water supplies and minimise the risk and impact of flooding.

The use of green infrastructure to minimise and mitigate the heating of the urban

environment.

Avoiding responses to climate impacts which lead to increases in energy use and carbon

dioxide emissions.

These measures should be integrated into the design of new development.

New development should demonstrate through Sustainability Statements how it would contribute to mitigating and adapting to climate change and to meeting targets to reduce carbon dioxide emissions by means of the above measures.

1.3.16. BCS14: Sustainable Energy – Proposals for the utilisation, distribution and development of renewable and low carbon sources of energy, including large-scale freestanding installations, will be encouraged. In assessing such proposals, the environmental and economic benefits of the proposed development will be afforded significant weight, alongside considerations of public health and safety and impacts on biodiversity, landscape character, the historic environment or the residential amenity of the surrounding area. […] Development in Bristol should include measures to reduce carbon dioxide emissions from energy use in accordance with the following energy hierarchy:

Minimising energy requirements;

Incorporating renewable energy sources;

Incorporating low-carbon energy sources.

1.3.17. BCS15: Sustainable Design and Construction – Sustainable design and construction will be integral to new development in Bristol. In delivering sustainable design and construction, development should address the following key issues:

Maximising energy efficiency and integrating the use of renewable and low carbon energy;

Waste recycling during construction and in operation;

Conserving water resources and minimising vulnerability to flooding;

The type, life cycle and source of materials to be used;

Flexibility and adaptability, allowing future modification of use or layout, facilitating future

refurbishment and retrofitting;

Opportunities to incorporate measures which enhance the biodiversity value of development,

such as green roofs.

South Bristol Link


13

New development will be required to demonstrate as part of the Sustainability Statement submitted with the planning application how the above issues have been addressed.

1.3.18. BCS16: Flood risk and water management – Development in Bristol will follow a sequential approach to flood risk management, giving priority to the development of sites with the lowest risk of flooding. The development of sites with a sequentially greater risk of flooding will be considered where essential for regeneration or where necessary to meet the development requirements of the city.

Development in areas at risk of flooding will be expected to be resilient to flooding through design and layout or incorporate sensitively designed mitigation measures, which may take the form of on-site flood defence works and / or a contribution towards or a commitment to undertake such off-site measures as may be necessary to minimise the vulnerability of the development to flooding.

All development will also be expected to incorporate water management measures to reduce surface water run-off and minimise its contribution to flood risks elsewhere. This should include the use of sustainable drainage systems (SUDS).

1.3.19. BCS22: Conservation and the historic environment – Development proposals will safeguard or enhance heritage assets and the character and setting of areas of acknowledged importance including:

Scheduled ancient monuments;

Historic buildings both nationally and locally listed;

Historic parks and gardens both nationally and locally listed;

Conservation areas;

Archaeological remains.

1.3.20. BCS23: Pollution – Development should be sited and designed in a way as to avoid adversely impacting upon:

Environmental amenity or biodiversity of the surrounding area by reason of fumes, dust,

noise, vibration, smell, light or other forms of air, land, water pollution, or creating exposure

to contaminated land.

The quality of underground or surface water bodies.

1.3.21. In locating and designing development, account should also be taken of:

The impact of existing sources of noise or other pollution on the new development; and

The impact of the new development on the viability of existing uses by reason of its

sensitivity to noise or other pollution.

Water quality and associated habitat of surface watercourses should be preserved or enhanced.

North Somerset Council Core Strategy, April 2012

1.3.22. NSC’s Core Strategy was adopted on 10 April 2012 and is the main planning document for North Somerset. It guides development choices and decisions on planning applications and sets out strategic objectives, strategies and policies for conservation and development in the district up to 2026.

1.3.23. The spatial policies are divided into four thematic areas to reflect the Sustainable Community Strategy:

living within environmental limits

delivering strong and inclusive communities

delivering a prosperous economy

ensuring safe and healthy communities

South Bristol Link


14

1.3.24. There are several relevant policies in respect of sustainability. Key aspects of each relevant policy are noted below:

1.3.25. CS1: Addressing climate change and carbon reduction – Development should demonstrate a commitment to reducing carbon emissions, including through reducing energy demand through good design, and utilising renewable energy. All developments are encouraged to incorporate site-wide renewable energy solutions.

1.3.26. CS2: Delivering sustainable design and construction – New development both residential (including conversions) and non-residential should demonstrate a commitment to sustainable design and construction, increasing energy efficiency through design, and prioritising the use of sustainable low or zero carbon forms of renewable energy generation.

1.3.27. CS3: Environmental impacts and flood risk assessment – Development that, on its own or cumulatively, would result in air, water or other environmental pollution or harm to amenity, health or safety will only be permitted if the potential adverse effects would be mitigated to an acceptable level. Development in zones 2 and 3 of the Environment Agency Flood Map will only be permitted where it is demonstrated that it complies with the PPS25 Sequential Test set out in the NPPF and associated Technical guidance and, where applicable, the Exception Test.

1.3.28. CS4: Nature conservation – The biodiversity of North Somerset will be maintained and enhanced by:

seeking to meet local and national Biodiversity Action Plan targets taking account of climate

change and the need for habitats and species to adapt to it;

seeking to ensure that new development is designed to maximise benefits to biodiversity,

incorporating, safeguarding and enhancing natural habitats and features and adding to them

where possible, particularly networks of habitats. A net loss of biodiversity interest should be

avoided, and a net gain achieved where possible;

seeking to protect, connect and enhance important habitats, particularly designated sites,

ancient woodlands and veteran trees;

promoting the enhancement of existing and provision of new green infrastructure of value to

wildlife; and

promoting native tree planting and well targeted woodland creation, and encouraging

retention of trees, with a view to enhancing biodiversity.

1.3.29. CS5: Landscape and the historic environment – The character, distinctiveness, diversity and quality of North Somerset’s landscape and townscape will be protected and enhanced by the careful, sensitive management and design of development.

1.3.30. The council will conserve the historic environment of North Somerset, having regard to the significance of heritage assets such as conservation areas, listed buildings, buildings of local significance, scheduled monuments, other archaeological sites, registered and other historic parks and gardens.

1.3.31. CS9: Green infrastructure – The existing network of green infrastructure will be safeguarded, improved and enhanced by further provision, linking in to existing provision where appropriate, ensuring it is a multi-functional, accessible network which promotes healthy lifestyles, maintains and improves biodiversity and landscape character and contributes to climate change objectives.

1.3.32. CS10: Transportation and Movement -Travel management policies and development proposals that encourage an improved and integrated transport network and allow for a wide choice of modes of transport as a means of access to jobs, homes, services and facilities will be encouraged and supported.

Bristol City Council’s Sustainable Building Design and Construction SPD, 2006

1.3.33. The Supplementary Planning Document (SPD) sets out Bristol’s commitment to achieving sustainable development through the planning process. The SPD advises that applicants for

South Bristol Link


15

planning permission should demonstrate how the following five sustainable design and construction aims will be achieved:

reduce overall energy use and maximise potential for renewable energy supply and use;

minimise waste and maximise re-use and recycling, both during construction and after

occupation;

conserve water resources, enhance water quality, incorporate water sensitive design and

minimise vulnerability to flooding;

minimise polluting emissions to water, air and soil and minimise noise and light pollution; and

maximise use of materials from sustainable sources.

1.3.34. The SPD advises that, for larger development sites, applicants should prepare a sustainability statement setting out how they have addressed the sustainability aims set above. The SPD also suggests that the statement can be based on a framework, consisting of key questions for each aim.

1.3.35. It should be noted that the SPD pre-dates BCC Core Strategy and is not necessarily fully aligned with the Core Strategy requirements in this regard, namely those in Policy BCS15 above. Nevertheless, it provides a useful checklist of decision-making questions organised by theme and has been used as the starting point for the development of the sustainability framework. In addition, the requirements contained in the BCC Practice Note below have also informed the development of the sustainability framework.

Bristol City Council Climate Change and Sustainability Practice Note, 2011

1.3.36. This practice note offers advice on the implementation of policies BCS13-16 of the Bristol Development Framework Core Strategy. Collectively, these form a suite of policies relating to climate change and sustainability. An SPD on Climate Change and Sustainability will be prepared in due course.

Sustainable Energy:

1.3.37. Policy BCS14 on Sustainable Energy has four main strands:

to encourage major freestanding renewable and low carbon energy installations;

to promote an energy hierarchy, prioritising energy efficiency;

to secure at least a 20% saving in CO2 emissions from energy use in new development

through on-site generation of renewable energy; and

to encourage the use of district heating schemes in new development.

1.3.38. The supporting text of Policy BCS14 states that energy strategies should be submitted with planning applications. These should include a feasibility study for sustainable energy and can form part of the Sustainability Statement.

Sustainable Design and Construction:

1.3.39. Policy BCS15 deals with the full breath of sustainable design and construction measures. As well as energy, development is expected to engage with the following issues (all of which should be addressed in the Sustainability Statement): waste and recycling; water; materials; flexibility and adaptability; biodiversity and Information Communication Technology (ICT).

1.3.40. Given the nature of SBL, it is considered that flexibility and adaptability (to potential future changes in use or occupancy of buildings) and ICT (new homes and workplaces to include the provision of high speed broadband) issues do not apply and are therefore not further considered in this sustainability statement.

1.3.41. Policy BSC15 also requires the submission of a Building Research Establishment Environmental Assessment Method (BREEAM) and/or Code for Sustainable Homes assessment with all planning applications for major developments (>10 dwellings or development >1000m

2), and

additionally a BREEAM Communities assessment for super major developments (>100 dwellings

South Bristol Link


16

or development >10,000m2). None of these assessments apply to transport schemes but it

should noted that a CEEQUAL assessment is an applicable alternative for infrastructure projects.

Flood Risk and Water Management

1.3.42. Policy CS16 requires development on sites at risk of flooding to be resilient to flooding through design and layout. The supporting text includes a requirement for a strategy for SuDS as part of the Sustainability Statement. In the case of SBL, water resources and drainage issues, including flood risk, are addressed as part of the Environmental Impact Assessment (EIA) process. The Sustainability Statement will take on board the findings and recommendations of the Water chapter in the ES.

Adaptation to Climate Change

1.3.43. Policy BCS13 requires applicants to set out how design and construction of the proposed development will provide adaptation to climate change, as well as mitigation.

CEEQUAL

1.3.44. North Somerset Council, as the lead authority for the SBL scheme, has applied for the scheme to be assessed for a CEEQUAL Whole Team Award, on behalf of the Client, Designer and Principal Contractor. The assessment of the scheme is on-going over the life of the scheme; however the verification and Award are to be granted at the end of construction.

1.3.45. CEEQUAL is the Civil Engineering Environmental Quality Assessment and Awards Scheme. It is a sustainability assessment rating methodology, initiated by the Institution of Civil Engineers, for the assessment of all types of civil engineering, infrastructure, landscaping and public realm projects and contracts. It uses rigorous evidence-based assessment criteria and external verification to allow clients, designers and contractors working on a project, to demonstrate or in some cases adopt best environmental practice and sustainable approaches and show how that project achieves high environmental, economic and social performance. Integration of the CEEQUAL question-set in the development of projects also positively influences design and construction management, often leading to better projects than would otherwise have been the case.

1.3.46. CEEQUAL uses the three-pillar model of sustainable development which seeks to achieve economic, social and environmental success at the same time. In this way it complements the planning system as the question-set can be used to influence the issues that are addressed in regulatory EIAs. Carrying out an assessment can also provide reassurances that projects are being carried out in an environmentally and socially responsible way.

1.3.47. The objectives of CEEQUAL are:

To create a climate of sustainability awareness and continuous improvement in the

profession and industry

To promote the importance of setting and delivering a sustainability-driven strategy for the

project or contract being assessed

To promote improved sustainability performance in project or contract specification, design

and construction

To recognise and promote the attainment of high economic, environmental and social

performance in civil engineering, infrastructure, landscaping and public realm works.

1.3.48. CEEQUAL assesses the extent to which the project or contract has exceeded the statutory and regulatory minima. The Award thresholds, based on the maximum possible score for the work are:

More than 25% – Pass

More than 40% – Good

More than 60% – Very Good

South Bristol Link


17

More than 75% – Excellent

The CEEQUAL assessment has been designed to reward efforts that go beyond the legal minima. Therefore

a ‘Pass’ at above 25% suggests that the project’s environmental and social performance is approximately

15-25% of the way from minimum legal compliance to the pinnacle best practice represented by the highest

achievable score.

1.3.49. The scheme is to be assessed using CEEQUAL Version 5. This comprises nine chapters, a brief summary of what each addresses are described below. The percentage scores are the respective weightings for each chapter:

1. Project Strategy (12.5%) – assesses how the project team has related their project to the

wider sustainability agenda surrounding civil engineering and infrastructure projects.

2. Project Management (10.9%) – considers how environmental and sustainability issues are

being incorporated into the overall management of the project.

3. People and Communities (10.6%) – addresses a wide range of positive and adverse

impacts on people affected by the project and/or on the wider communities served by or

affected by the project.

4. Land use and Landscape (20.0%) – covers issues affecting land above and below water

such as design for optimum land-take, legal requirements, flood risk, previous use of the

site, land contamination and remediation measures.

5. The Historic Environment (4.6%) – baseline studies and surveys, conservation and

enhancement measures to be taken if features are found, and information and public

access.

6. Ecology and Biodiversity (6.0%) – impacts on sites of high ecological value, protected

species, biodiversity conservation and enhancement, habitat creation measures, monitoring

and maintenance.

7. The Water Environment (5.7%) – control of a project’s impacts on, and protection of, the

water environment, legal requirements, minimising water usage, and enhancement of the

water environment.

8. Physical Resources Use and Management (24.3%) – life-cycle energy and carbon

analysis, energy and carbon emissions in use, and energy and carbon performance on site,

minimising environmental impact of materials used, minimising material use and waste,

responsible sourcing of materials (including timber), using re-used and/or recycled materials,

minimising use and impacts of hazardous materials, durability and maintenance, and future

de-construction or disassembly, waste management.

9. Transport (5.4%) – covers location of a project in relation to transport infrastructure,

minimizing traffic impacts of a project, construction transport, and minimising workforce

travel.

Derivation of sustainability framework and decision-making questions

1.3.50. The derivation of the sustainability framework started with reviewing the BCC Sustainable Design and Construction SPD and identifying sustainability topics and decision-making questions of relevance to the rapid transit schemes. Non-applicable questions were scoped out. This was mainly the case where the SPD questions applied to residential and mixed-use schemes, rather than to transport and infrastructure schemes.

1.3.51. Additional questions were then added (shown in italics) to cover the sustainability considerations identified in the rest of the reviewed local policy documents: BCC and NSC Core Strategies and BCC Climate Change and Sustainability Practice Note.

1.3.52. The identified sustainability topics and decision-making questions that were used to develop the sustainability framework are shown below.

(SGC Core Strategy; this question is linked to HIA)

Will public art be part of the scheme, if appropriate? (SGC Core Strategy and

Design Checklist SPD)

1.3.53. Additionally the CEEQUAL question-set was cross-referenced with the above decision-making questions to enable progress and compliance with these questions to be more practically and easily monitored using the CEEQUAL assessment process.

Consultees’ Comments

1.3.54. BCC and NSC were both consulted on the proposed approach to the sustainability framework and decision-making question, which are summarised below:

Given the sustainable transport objectives of the SBL scheme, there should be an

aspirational target rating of “Very Good” for the CEEQUAL assessment.

If possible, there should be some feasibility work to see if there are opportunities for

integrating sustainable energy measures. Possibilities could include consideration of adding

district heating infrastructure to new or adapted road and PV panels on any structures, e.g.

bus stops.

The topic on local community and wellbeing should be strengthened this with a reference to

health.

All local authorities’ policies, including NSC, should be included in the framework, with clear

policy/context sections for each local authority.

The statement itself should be a summary of the outcomes of the process, setting out how

well the project has performed in sustainability terms, with signposting to relevant sections in

the ES.

The statement should respond to questions such as what value the sustainability process

added to the design and development of the proposal.

1.3.55. Amendments have been made to the appropriate decision-making questions to incorporate these comments. Policy frameworks of both local authorities were reviewed to establish the sustainability framework and decision-making questions. This is set out in the sections above.

1.3.56. The last two comments have been taken on board during the preparation of the Statement, and in coordinating the sustainability work with the project designers and topic specialists involved in the preparation of the ES.

Table 1. Sustainability Framework

Sustainability topic and decision-making questions Relevant question-set within the CEEQUAL assessment and examples of how a project can achieve a high score.

Energy

How will the scheme’s design ensure the efficient use of energy and reduce overall energy use?

Chapter 8 (Physical Resources – Use and Management).

Section 8.2 (Embodied Impacts)

To attain a high score, evidence would need to show that, within the project, consideration has been given to things such as; a life-cycle assessment of the key materials and components used; consideration of various options to reduce the energy consumption of the project during construction through the way materials are brought to site, selection of construction practice to minimise energy consumption, selection and maintenance of construction plant; and in operation through the designing out of the use of energy-consuming equipment and energy requirements in maintenance.

How will the scheme’s design incorporate the use of energy from renewable or low carbon sources? Will the scheme consider site-wide renewable energy solutions such as adding district heating infrastructure to new or adapted road and PV panels on any structures?


Section 8.4 (Design for reduced energy consumption and carbon emissions in use)

Section 8.5 (Energy and carbon performance on site)

To attain a high score evidence would need to show that the project has explored opportunities for the incorporation of energy from renewable and/or low- or zero-carbon sources; and whether these opportunities have been incorporated in the project.

A project will score points in Section 6.3 where it can demonstrate recommendations in the design that conserve or enhance existing ecological features of the site and also within Section 7.4 if it can demonstrate whether opportunities to improve the local water environment have been included in the design for amenity reasons.

Pollution

How will the scheme’s development clean up any contamination on site and/or avoid land contamination in future?

Chapter 4 (Land use and Landscape). Section 4.2 (Contamination of land) Projects can score points if they can demonstrate that desk studies have been undertaken to assist the client in deciding that the chosen site is suitable, including collation of information on past and current land uses, site sensitivities and land condition. Where contaminated land is present, projects can score further points if land contamination management procedures have been implements, if the evaluation and consequent implementation of a remediation option has been undertaken and whether measures to prevent future contamination have been addressed.

How will pollution of all kinds be minimised during construction?

This question is addressed in CEEQUAL in a number of sections. At a general level a project will score points if it can demonstrate commitment to the adoption of an active environmental management system (EMS) or similar, designed to identify and manage

'very good' and 'excellent' being sought?

SBL is being assessed for a CEEQUAL Whole Project with Interim Award. The aspiration is that the scheme will score ‘Very Good’.


Will there be loss of green infrastructure as a result of the scheme? If so, will there be adequate mitigation?

Chapter 4 (Land use and landscape) Section 4.1.5 (Previous use of the site) A project can score highly in this section where it can demonstrate that the site chosen for the development avoids un-developed land. Where this is unavoidable, there are other sections within the assessment that allow a project team to demonstrate what mitigation measures they have used to minimise the effects on un-developed land.


Chapter 4 (Land use and landscape) Section 4.5.3 Existing vegetation Chapter 6 (Ecology and biodiversity) Section 6.4 (Habitat creation measures) This issue does not have a specific question-set within the CEEQUAL assessment however, the project could score points in the above sections if evidence can be provided on how the design has integrated and retained vegetation within the proposals and improved existing wildlife habitats

Biodiversity

Will the scheme be designed to maximise benefits to biodiversity, incorporating, safeguarding and enhancing natural habitats and features and adding to them where possible? Will it lead to a ‘net gain’ in biodiversity?

Chapter 6 (Ecology and Biodiversity). An entire chapter in the CEEQUAL assessment is provided in order to assess how a scheme effects biodiversity. A project will score highly where it can demonstrate and provide evidence for a wide range of ecological aspects surrounding the project site and how it is affected by the design of the project. Examples of this will be how a project minimises its impact during construction and operation, and the extent the project team have gone to introduce improvements Projects can score points if they demonstrate the conservation of existing ecological features.or the extent with which they mitigate against ecological loss, can demonstrate a net increase in wildlife habitat area relative to a baseline figure or where special structures or facilities for encouraging or accommodating appropriate wildlife have been implemented.

Will the scheme promote native tree planting and encourage retention of trees, with a view to enhancing biodiversity?

Chapter 4 (Land use and landscape). Section 4.5.3 Existing vegetation Section 4.5.6 Appropriateness of species selected Evidence that a design has retained existing vegetation will score more points in this section depending upon the % of vegetation retained which also rewards projects that, if necessary adapt designs to allow for their retention. Points will also be scored where evidence is provided to show how the existing vegetation has influence the planting proposals for the design. Improvements in biodiversity are addressed in Chapter 6 as described above.


Will it safeguard or enhance heritage assets and the character and setting of areas of acknowledged importance including Scheduled Monuments; Historic buildings both nationally and locally listed; Historic parks and gardens both nationally and locally listed; and Conservation areas?

Chapter 5 (The historic environment). To score points within this question-set, evidence needs to show how a project has reviewed all heritage assets not only within the immediate footprint of project but on a wider scale. Where assets are affected, a high score can be attained if the project can demonstrate amongst other things; - Baseline studies and surveys - Management plans or other records - Consultation with relevant authorities - Measures taken to avoid the asset or protect it during construction - Where a design has taken measure to enhance any setting issues - If restoration is required, have appropriate materials and skilled labour been used


Will the scheme be carefully designed so as to protect and enhance the character, distinctiveness, diversity and quality

of the landscape and townscape? There are a number of questions where a project can score points within the above sections where consideration has been given to issues of character, diversity and quality of the landscape and townscape. For example, a high score can be achieved where a project has considered landscape issues at all stages of the project, and that it has ensured that the design fits with the local landscape/townscape character. Points can be awarded where evidence is given to show where loss of valuable, distinctive or historic landscape features has been avoided.

Travel

Will the scheme improve accessibility within Bristol and support the proposed levels of development?

Will the scheme be part of an improved and integrated transport network and allow for a wide choice of sustainable modes of transport as a means of access to jobs, homes, services and facilities?

Chapter 1 (Project Strategy). Chapter 9 (Transport) Overall strategy and objectives for a project are scored in Chapter 1. A project will score very highly where evidence can show that the project has actively adopted the principles of sustainable development in the planning and design of the project. The transport chapter includes more a more specific question-set that assesses how a project affects the existing transport network. In order to score, evidence will need to show how the project provides a beneficial impact e.g by providing new PROW/footpaths, or, if the impact is negative, how the design proposes to mitigate this, e.g. by providing a PROW diversion.

Will existing public rights of way be safeguarded and enhanced through incorporation into the scheme?

Will construction traffic effects be minimised? Chapter 9 (Transport) Section 9.3 (Construction transport including nuisance and disruption) A project that recognises the effect it will have on the local and wider transport network and includes measures to minimise these impacts can attain a high score in this section. Evidence can be in the form of; - Construction Environment Management Plans - Traffic management drawings - Evidence of consultation with residents, businesses or other stakeholders to explain the traffic management proposals in advance..


Is community consultation being undertaken as part of the development of the scheme design?

Chapter 3 (People and Communities) Section 3.2 (Consultation with stakeholders) Section 3.5 (Continuing engagement with relevant local interest groups) In order to score within this section, evidence will need to be provided to show that the local and wider community, statutory authorities and agencies and local interest groups has been undertaken across the lifetime of the project.

considered its effect on the health and welfare of occupants, users, neighbours and/or any operational staff. Points will be awarded if there is evidence showing that the project design has been modified as a result; and that the needs of all different user groups have been considered and respected in the design solution (for example, car drivers, cyclists, pedestrians, disabled people etc) and the specification achieved in the completed project?

Will the scheme be designed for low traffic speeds in particular in residential and retail areas and when it survives as a route to schools?

This aspect is not considered specifically in CEEQUAL, however if measures within the design are adopted to support this particular issue, the evidence can be used to score points within a number of sections in the assessment.

Will the scheme take account of personal safety, security

and crime prevention?

Chapter 3 (People and Communities) Section 3.7.2 (Health and welfare issues) This is not considered specifically in CEEQUAL, however any evidence to show that a project has considered its impacts on the construction workforce, occupants, users, neighbours or operational staff and the design modified as a result will enable it to score points in this section.

Will public art be part of the scheme, if appropriate? Chapter 3 (People and Communities) Section 3.7.4 (Enhancement beyond functional requirements) This aspect is not considered specifically in CEEQUAL, however any evidence to show that a project has included public art as part of the scheme will enable it to score points within this section.

Table 2. Sustainability Assessment

Sustainability topic and decision-making questions

Relevant considerations within the CEEQUAL assessment How sustainability considerations addressed in the scheme design

Additional sustainability recommendations

Energy

How will the scheme’s design ensure the efficient use of energy and reduce overall energy use?

Energy use of the completed project is considered in Chapter 7 (Energy and Carbon). CEEQUAL asks projects to undertake a life cycle assessment of the key materials and components used; and to consider options to reduce the energy consumption of the project during construction through the way materials are brought to site, selection of construction practice to minimise energy consumption, selection and maintenance of construction plant; and in operation through the designing out of the use of energy-consuming equipment and energy requirements in maintenance.

Further credits are awarded for the implementation of any of the options identified/considered for carbon emission reduction above 10%.

A life cycle assessment of the key materials and components used and the consideration of options to reduce the energy consumption have not been undertaken at this planning stage.

It can be inferred that energy use will be reduced through the efficient use of materials during the construction (see the SWMP). The re-use and recycling of materials on site will help reduce embodied energy and minimise the need for the transportation of materials and waste. This, in turn, will help reduce transport-related energy use.

In addition, the PCEMP stipulates the development of a Green Travel Plan (GTP). The GTP will promote travelling to/ from site using car sharing/ public transport and managing deliveries and removal of materials and equipment in an efficient and sustainable way.

Further, lighting systems will be more energy efficient than existing systems, where existing systems will be replaced (see the Lighting Impact Assessment).

The CEMP should identify opportunities for reducing energy use and energy efficiency throughout the following stages:

Materials production

Materials transportation (limiting haul distances)

The Scheme’s operation

The Scheme’s maintenance

Calculate life cycle energy use and set project baseline.

Set ambitious emissions reduction targets for each stage.

Consider opportunities for renewable and low carbon energy technologies to meet the projected overall energy use (embodied and in use).

How will the scheme’s design incorporate the use of energy from renewable or low carbon sources? Will the scheme consider site-wide renewable energy solutions such as adding district heating infrastructure to new or adapted road and PV panels on any structures?

CEEQUAL asks specifically if the project has explored opportunities for the incorporation of energy from renewable and/or low- or zero-carbon sources; and whether these opportunities have been incorporated in the project.

The type of renewable system is not specified, apart from whatever is used is appropriate for the scale of the project.

Carbon emission reduction identified in the life-cycle assessment should be above 10% to receive credits.

An energy feasibility energy study has not been undertaken at this planning stage.

Waste, recycling and re-use of resources

How will the scheme provide space or facilities for the separate collection of all materials that can be recycled, or easy access to recycling facilities?

This aspect is not covered specifically in the CEEQUAL process. The construction stage will include on-site waste recovery and re-use. This is specified in a Site Waste Management Plan (SWMP) – see below.

The project documentation does not currently include details on the provision of facilities for separate waste collection as part of the scheme.

None identified.

How will the scheme’s development re-use demolition, construction or other reclaimed wastes on or close to the site and/or from elsewhere?

Re-use of site won materials (including demolition materials) either within the site or close to the site is a key component of the Materials Use and Waste Management chapters (Chapters 8 and 9 respectively).

Volume of materials from reclaimed or recycled material for use in the permanent works should be above 5% to have credits awarded.

Volume of bulk fill and sub-base material specified and used in the project from previously used material should be above 20% to receive credits.

Credits are scored for projects that maximise the use of their on-site demolition materials; and thereby reduce the quantity of demolition materials sent to landfill. Further credits are scored for projects that are able to modify their design or construction methods so that site-

The SWMP has been produced with the aim of reducing/reusing/recycling and managing the disposal of the anticipated waste safely from the preparation and concept design stage to post completion and use stage. The Plan is based on the Waste and Resources Action Programme (WRAP) workbook. It is a comprehensive document that identifies types of construction waste, expected (and actual) tonnage, management actions for each different waste type and costs of disposal. The SWMP is a live document that will require monitoring, review and updating by the Principal Contractor (PC) during the course of the construction phase to be effective.

The SWMP includes a list of waste prevention and waste minimisation measures such as optimisation of alignment to minimise impact on

It is recommended the SWMP KPI adopt ambitious targets and use CEEQUAL to provide the framework.

The nature of the project means that CEEQUAL targets for re-use and recycling of materials may not be appropriate (either too low or too high).

Consideration of other relevant specifications (e.g. inert waste, non-hazardous waste material) should be included.

won materials can be utilised. Re-use of excavated material on-site should be above 15% to receive credits.

More than 30% of volume of material present on site (excluding topsoil and subsoil) should be incorporated into the project, as opposed to being disposed of to receive credits. There are also a number of other specifications in relation to inert waste, non-hazardous waste material, etc.

undisturbed ground, to optimise cut and fill volumes and re-use excavated topsoil on site.

The SWMP is included in Appendix A of the PCEMP.


CEEQUAL addresses the issue of minimising waste of new construction materials at several levels:

- That the waste minimisation is considered at design stage to

reduce wastage of materials at construction.

- That the use of prefabricated materials and/or components is

considered and implemented; and

- That materials are stored correctly at the construction site to

avoid loss through breakages.

Will soil resources be protected? CEEQUAL requires that topsoil is re-used beneficially as topsoil on the site or on a site within a reasonable distance to achieve credits.

The quality and quantity of soil on site would be maintained by implementing appropriate techniques for stripping, storing and re-use. This approach would be adopted in a Soil Handling and Management Strategy (SHMS), which would in due course form part of the CEMP (ES Land Use Chapter, construction impacts section).

The SWMP identifies two waste reduction actions in relation to topsoil:

- Top soil to be stripped in various areas that have different characteristics due to the seedbank contained within. The topsoil will be stored and translocated to specific sites in order to provide suitable growing medium of local provenance.

- All excavated topsoil to be re-used on site.

A Construction Soil Management Plan will be included within the CEMP with a view to protecting soils, managing and reducing the risk of soil erosion happening as a result of the construction activities (PCEMP, Section 2.7).

Where possible, loss of agricultural land would be minimised by careful engineering design, sensitive landscape works and restoration of disturbed land (ES Land Use Chapter, construction impacts section).

None identified.

Water

How will any vulnerability to current or future flooding be minimised?

Flood risk is considered in a separate section within the Land Use chapter (Chapter 2).

CEEQUAL asks whether the run-off, flood risk, and potential increased flood risk elsewhere as a result of the completed works have all been assessed over their expected working life, in line with the requirements of PPS25 in England and TAN15 in Wales (superseded by NPPF), PPS15 in Northern Ireland or equivalent, and appropriate flood resilience measures included in the design.

CEEQUAL also asks whether the project has actively considered the merits of designing for a larger event or for greater flood resilience than required by PPS25 or the appropriate equivalent, and if so whether this has been incorporated into the project.

The FRA and Drainage Strategy developed in consultation with the Environment Agency, NSC and BCC conclude that the scheme has a good level of protection against flooding (generally better than a 1% AEP event plus climate change).

The scheme was assessed over its design life of 60 years.

Both fluvial/tidal and surface water flood risks have been considered, and both allow for climate change impacts using the accepted guidance. A number of flood resilience measures are incorporated in the design (ES Chapter 18 Flood consequences, sections 18.1.1 and 18.6). These include both conventional methods such as culverts and low impact development measures such as dispersion and transpiration through the use of Sustainable Urban Drainage Systems (SUDS), e.g.:

a) Road levels are set to a minimum level of 1% AEP event (including an allowance for climate change) plus 0.6m freeboard.

b) Proposed culverts will be sized to convey the 1% AEP event

The scheme already incorporates a range of design measures to reduce flood risk and achieve “natural” conditions as a baseline for performance.

South Bristol Link


32

(including climate change) with a 0.3m allowance for freeboard.

b) SUDS (e.g. detention basins) to attenuate additional runoff. Discharge from surface water detention basins would meet Greenfield run-off rates.

c) Carriageways will be above known historical groundwater levels to ensure no known groundwater flood risk during operation

c) A compensatory flood storage area will provide an additional 15,000m³ of storage capacity and result in betterment in flood risk between the New Colliter’s Brook and Ashton Brook.

The impacts of flooding on the scheme from more extreme events (i.e. the 1000-year event) have been considered and Flood Management Plans will be developed where necessary to manage such risks.

How will discharges of polluted waters be minimised?

Minimising discharges to the environment is considered both generally and specifically within the CEEQUAL assessment.

At a general project level CEEQUAL asks (in the Project Management chapter) if the project has produced a pollution control plan designed to minimise emissions of the completed works to air, land and water?

With regard to the water environment, CEEQUAL asks if a plan to control the impacts of the project on the water environment during construction been produced and implemented, and if specific measures have been taken to prevent pollution or physical damage of groundwater or existing water features?

The PCEMP identifies the need to set out how the water courses will be protected in the CEMP. The CEMP would be compiled to provide targeted guidance throughout the construction period. This would detail both generic and specific instruction to enable construction to be undertaken with minimal impact on the water environment and ensure appropriate consents for abstractions and discharges are obtained prior to works commencing.

The ES Water Quality Chapter concludes that the significance of effects on each attribute of the water environment, based on environmental importance and magnitude of impact both during construction and operation, ranges from neutral to slight beneficial.

The ES Water Quality Chapter identifies mitigation measures for construction and operation phases (section 1.7). Construction mitigation include such measures as:

- designing temporary site drainage to retain surface run-off within the site boundary where practicable. Where possible the permanent drainage arrangements would be utilised in the temporary management system;

- sediment Erosion Management Plan controls;

- grey water systems would be used at site compounds to reduce run-off from site, improve water efficiency and lessen the potential for polluting discharges to surface watercourses where practicable;

- uses that could generate contaminated water, such as refuelling areas, would be bunded and would drain to lagoons that would have oil interception facilities. There would be no discharge to groundwater. An incident response plan would be put in place during construction too;

- all plant would be regularly inspected for leaks and refuelling would take place on sand mats to prevent discharge to watercourses;

- all water upstream of a culvert would be over pumped into a manhole allowing settlement of silt before discharge downstream.

First choice would be discharge to foul water connections to local authority sewers. Second option would be an onsite water treatment plant with treated effluent discharged to a watercourse meeting discharge consent

Where possible rainwater harvesting would reduce surface water run-off. Next preference would be to discharge toward a bypass oil separator that would drain to storage with a facility to shut off flow in the event of a spillage. This would then discharge to a watercourse

Additional mitigation has been proposed for catchment B in the form of a pollution device similar to a downstream defender, to ensure some removal of some sediments and related metals.

Water quality tests demonstrated that even without mitigation all individual discharges would meet the required runoff thresholds and

The mitigation measures set out in ES Water Quality Chapter should be incorporated in the CEMP.

33

standards. The adoption of additional mitigation measures will provide benefit. SUDS options appropriate for the scheme include detention basins (to retain and treat the most polluted water from the rainfall runoff) and attenuation tanks (both surface and underground).

Will water use be minimised? CEEQUAL asks about measures to reduce consumption of water in operation and construction. Water consumption in construction is of relevance for this type of project.

As above – wherever practicable, grey water systems would be used at site compounds to reduce run-off from site, improve water efficiency and lessen the potential for polluting discharges.

The PCEMP should identify the need for minimising water consumption in construction and stipulate that this aspect should be covered in the CEMP.

How are the aims of enhanced amenity and biodiversity being addressed through water sensitive design?

Whilst this aspect is not covered specifically, CEEQUAL asks whether opportunities to improve the local water environment been included in the design and implemented. Improvements could be for amenity or biodiversity reasons.

Water quality tests have considered ecological effects (ES Water Quality Section 1.4).

A series of waterbodies will be created along the scheme, including two attenuation ponds (to compensate for the loss of two ponds during construction) and seven surface water detention basins (ES Ecology Chapter, Section 1.7.3 and ES Water Quality Section 1.7.2.3). These will have a variety of functions including providing habitat for wildlife, and providing surface water attenuation and filtering.

The attenuation ponds have been designed for the benefit of wildlife with shallow margins allowing growth of emergent and marginal vegetation. The ponds will be planted with native marginal aquatic plant species, and are likely to become further colonised by a range of plants, invertebrates, amphibians and reptiles (ES Ecology Chapter, Section 1.7.3).

A number of expected improvements are briefly outlined below.

As part of Colliter’s Brook realignment works the Environment Agency are supportive of the enhancement option to create wetland features within existing meander bends to provide additional aquatic habitat.

Localised changes in the riparian zone on the Colliter’s brook will occur as a result of the new detention ponds where permanent ponds will replace areas of the existing floodplain. As a result some additional diversity of habitat will occur as these areas become damper.

On the Colliter’s Brook tributary, 380m of culvert is to be restored. Creating a meandering restored channel with natural features and planting rather than a trapezoidal channel will maximise the potential of any aquatic habitat gain which can be achieved. It is recommended at the detailed design stage that this option is assessed to ensure the optimal route for the new channel is achieved which maximises any restoration potential and reduces any erosion risks.

This should have an overall neutral or positive impact on the tributary, allowing the establishment of an increased amount of aquatic habitat and an expansion in range of any aquatic ecology present on the Colliter’s Brook.

All new culverts are to include a mammal ledge and a depressed invert to encourage fish passage.

None identified.

Pollution

How will the scheme’s development clean up any contamination on site and/or avoid land contamination in future?

Remediation of contaminated land is addressed by CEEQUAL in a separate section of the Land Use chapter.

Avoiding future contamination is addressed through the implementation of a pollution control plan covering the operational phase of the project, and future monitoring to confirm that contamination does not occur.

The contaminated land section addresses the selection and implementation of remediation measures, and the management of ground generated gases.

CEEQUAL checks if a desk study has been undertaken to assist the

The PCEMP (Section 3) specifies that a contaminated land specialist (CLS) will be appointed to inspect the excavations and advise on contamination issues.

The quality and quantity of soil on site would be maintained by implementing appropriate techniques for stripping, storing and re-use. This approach would be adopted in a Soil Handling and Management Strategy (SHMS), which would in due course form part of the CEMP (ES Land Use Chapter, construction impacts section).

client in deciding that their chosen site is suitable, including collation of information on past and current land uses, site sensitivities and land condition.

CEEQUAL rewards Brownfield land development.

The ES Ground Conditions & Land Contamination Chapter addresses effects associated with land contamination that may already exist on site, effects associated with the potential for polluting substances used and impacts associated with re-use of soils and waste soils.

The following mitigation measures are set out in this Chapter:

- Re-use of soils/materials – a Materials Management Plan (MMP) will be prepared to manage and control the import of fill materials and appropriate reuse of excavated material within the scheme. This will be in accordance with the CL:AIRE code of practice. The MMP will provide the framework by which material will be managed on the site and will ensure that the fill materials imported to the site or reused are suitable geotechnically and will not pose a risk to human health and the environment.

- Redevelopment of brownfield land – the scheme crosses through two historical landfills and one permitted landfill. The design of the scheme has used information from a desk study and a 2011 ground investigation. Further ground investigation and assessment is required to complete the detailed geotechnical design of the scheme through the landfill areas.

The ES Water Quality Section stipulates that detention basins located in areas of historical landfill are to be fully lined with an impermeable membrane such as Bentonite Geotextile or similar approved. No discharge directly to ground.

How will pollution of all kinds be minimised during construction?

Addressed in CEEQUAL at a general level through the project requiring an active environmental management system designed to identify and manage potential environmental issues (including pollution) through the lifetime of the project.

At construction stage this is addressed specifically through a Pollution Control Plan (as a standalone document or as a section of the Site Environmental Management Plan) being required at construction stage.

Minimising pollution impacts from noise, vibration, dust, emissions to air and light at construction stage are considered in the Effects on Neighbours chapter (Chapter 11). Credits are awarded to projects that take active steps to minimise or eliminate these pollution issues.

The PCEMP, which will be developed into a full CEMP, aims to reduce the risk of adverse impacts of construction on sensitive environmental resources and minimise disturbance to local residents.

The PCEMP (and subsequently CEMP) identifies management responsibilities and environmental impacts that may occur, including impacts on air quality, implications to residents in the vicinity of the construction works such as traffic, negative effects on water resources such as pollution and detrimental effects on ecology.

The PCEMP include some measures that will be implemented to control and monitor the identified environmental impacts. The CEMP will develop further the list of potential effects and measures to control them, drawing on all the relevant environmental requirements and documents produced for the SBL scheme such as the EIA, ES and SWMP.

As per mitigation in the ES Chapters on Air Quality, Noise, Ground Conditions, Water Quality and Lighting Assessment.

How will the scheme’s development impact on external air quality?

Effects to air quality of the completed project (in operation) are considered specifically in the Effects on Neighbours chapter (Chapter 11). CEEQUAL asks if measures to minimise impacts to external air quality have been considered and then implemented.

The ES Air Quality Chapter concludes that negligible residual effects are expected to occur as a consequence of the SBL construction assuming that appropriate mitigation measures to prevent and control dust emissions are maintained by the construction contractor. The Chapter lists typical mitigation measures to be included in the CEMP:

- Erect solid screens or barriers around the site boundary where there are adjacent residential properties.

- Only use cutting, grinding or sawing equipment fitted or in conjunction with suitable dust suppression techniques such as water sprays or local extraction, e.g. suitable local exhaust ventilation systems.

- Damp down dusty materials and exposed surfaces during dry weather.

- Ensure sand and other aggregates are stored in bunded areas and are not allowed to dry out.

- Use enclosed chutes, conveyor and covered skips where practicable.

Construction impacts should be mitigated through the inclusion and implementation of mitigation measures identified in the ES Air Quality Chapter.

- Make sure that any stockpiles exist for the shortest possible time.

- Avoid creating steep sided stockpiles or mounds or those that have sharp changes in shape.

- Whenever possible keep stockpiles or keep them securely sheeted.

- Take into account the predominant wind direction when locating stockpiles to reduce the likelihood of affecting sensitive receptors.

- Send, re-vegetate or turf long term stockpiles to stabilise surfaces.

- Impose an appropriate onsite speed limit.

- Ensure that all vehicles carrying dusty material should be securely covered before leaving the site.

- Regularly inspect and maintain all site access points and the public highway in the vicinity of access points free from accumulations of mud and other debris.

- Employ vehicle cleaning equipment to ensure that vehicles leaving the site do not track mud onto the public highway.

No significant adverse residual effects are expected to occur as a consequence of the SBL after opening. No specific mitigation is therefore required. (ES Air Quality Chapter 1.5).

Will noise pollution from the scheme be minimised?

Minimisation of noise pollution is addressed through CEEQUAL asking projects to review baseline noise levels, and then to develop proposals at design stage for mitigating noise levels during construction and operation (with further credits awarded for their implementation).

Minimisation of noise pollution from external sources is only considered indirectly with CEEQUAL asking how the project has considered the health and welfare of occupants and users, in the Relations with the Local Community chapter (Chapter 12).

On opening there are approximately 1100 properties with perceptible increases in noise and approximately 2100 properties with perceptible decreases in noise. The greatest noise increases occur in the reserved corridor and the greatest decreases in noise occur along parts of Highridge Green. By the design year the project would result in there being more perceptible increases in noise than perceptible decreases in noise. A comparison in the design year shows that there are approximately 520 perceptible increases in noise all within 600m of the scheme and 210 perceptible decreases in noise occurring within 1500m of the scheme.

If the scheme was not built, no properties would experience anything greater that a negligible change in noise level.

Results with AVTM included under the cumulative impacts assessment would be similar.

The design of the South Bristol Link scheme includes mitigation in the form of noise barriers where practicable and appropriate and or secondary insulation. It is considered not practical to use barriers to mitigate against noise level increases along parts of the reserve corridor, King Georges Road and Highridge Green due to residential access requirements and landscape, visual and community connectivity issues. (See the ES Noise and Vibration Impact Assessment Chapter, Conclusions section).

As stipulated in the ES Noise and Vibration Impact Assessment Chapter – in order to follow the aims of the NPPF and Noise Policy Statement for England, mitigation should be employed to minimise adverse impacts at NSRs. Mitigation measures should be finalised in the detailed design.

It is recommended that the following mitigation measures are considered:

- Construction noise impacts should be mitigated using best practicable means and set out in the CEMP for the scheme.

-consideration should be given to working hours, temporary noise barriers, erected for the duration of the construction works and to early installation of permanent noise barriers and . window treatments on buildings.

How will obtrusive light from the scheme be minimised?

Minimisation of obtrusive light is addressed through CEEQUAL asking whether measures have been taken at design stage to prevent light spillage to neighbouring areas during construction and operation (with further credits awarded for their implementation).

Obtrusive light has been reduced by choice of quality lighting products and compliance with the Institution of Lighting Professionals (ILP) guidance note on Obtrusive Lighting (ILP Guidance Note GN01:2011) and the SLL Guide ‘To Limiting Obtrusive Light 2012’ (see the Lighting Impact Assessment).

The results of the Lighting Assessment are included in the ES Landscape Chapter.

The assessment states that the extent and operational use of lighting should be minimised. Motion sensitive lighting should be designed not to be triggered by single movements or wildlife movements. Lighting generally should be mounted on structures, to avoid daylight visual impact of posts (ES Landscape Chapter, section 12.6.1). The ES Ecology Chapter proposes that there should be no street lighting for majority of rural section of the scheme.

None identified.

South Bristol Link

Further mitigation measures include the following:

- - Obtrusive lighting criteria in the ILP GN01 should be met and

curfews applied where immediately adjacent to residential properties

(e.g. Waverley gardens and Highridge Green).

- - Apply GN01 and look to use high quality flat glass luminaires

with low levels of glare and utilise house side shields where

appropriate.

Materials

How will the materials be specified to help maintain local character and ensure long life?

This is addressed by CEEQUAL in two ways:

- Local character is considered within the Landscape chapter

(Chapter 3), with CEEQUAL asking specifically how material

selection fits with the local character.

In the Material Use chapter (Chapter 8), the durability and maintenance section asks that durability of structures and components is actively considered in design and specification.

The DAS and ES Landscape Chapter do not discuss how material selection fits with the local character, apart from specifying that a new Rail Bridge should be constructed with materials and finishes to reflect existing bridge (retained for non motorised access) such as weathered steel to replicate historical context (ES Landscape Chapter, section 12.6.1).

The SBL CEEQUAL awards 36% of credits available for Section 8 – Physical resources use and management. This is a relatively low score.

Consider use of BES6001 Framework Standard for the Responsible Sourcing of Construction Products (Oct 2008), and BS 8902:2009 – responsible sourcing sector certification schemes for construction products – Specification

Will materials be specified based on life cycle and sourcing considerations? Will commitment be made to using materials rated A or B in the BRE Green Guide to Specification?

The responsible sourcing section of the Material Use chapter asks for evidence that responsible sourcing of materials has been specified from early on in the project, and whether the project has researched all locally available materials, and if necessary adapted design/specification to enable their use.

Life cycle considerations are addressed in the Project Management chapter (Chapter 1), with CEEQUAL projects to demonstrate that a whole life approach to environmental aspects of the project. This would include materials.

A life cycle assessment of the key materials and components used has not been undertaken at this planning stage.

A life cycle assessment of the key materials and components used should be undertaken at the next planning stage.

In addition to the BRE Green Guide to Specification, consult BES6001 and BS8902.


Will the scheme’s design be assessed against an accredited scheme such as CEEQUAL with a target rating not less than 'very good' and 'excellent' being sought?

Achieving at least CEEQUAL very good ensures the scheme has a robust approach to sustainable design and construction, covering 12 areas.

SBL has been assessed against CEEQUAL separately and both schemes are assessed against the sustainability assessment framework incorporating CEEQUAL considerations.

Various elements of sustainable design & construction related to the scheme are addressed through compliance with CEEQUAL, BRE Green Guide to Specification, the PCEMP, ES and DAS.

The draft SBL CEEQUAL assessment indicates that the scheme’s rating is ‘Good’ (>56%)

2. It is likely that the final CEEQUAL will score

the VERY GOOD mark (over 60%).

Environmental sustainability is comprehensively addressed through the application of CEEQUAL. Targets would ideally be set at the upper end to achieve ‘excellent’ rating.

Social and economic sustainability is not comprehensively addressed through CEEQUAL and therefore should be captured within the ES scope.

The scheme should meet CEEQUAL ‘Very Good’ or ‘Excellent’ rating. As there is always the risk that the scheme’s score will be revised down by the Verifier, an ambitious target should be set up.


Will there be loss of green infrastructure as a result of the scheme? If so, will there be adequate mitigation?

CEEQUAL seeks to reduce loss of greenfield land by penalising projects that use greenfield sites for both permanent works and temporary construction compounds.

Landscape impacts have been considered in the ES Chapter ‘Landscape, Townscape and Visual Impact Assessment’. The scheme is situated within a nationally designated Greenbelt. The scheme will have slight to moderate adverse effects on features of high value, i.e. nature conservation, ancient woodland, mature trees and hedgerows.

The five sections of the scheme are addressed in turn. Proposed

landscape mitigation measures aim to retain green corridors and establish a buffer around impacted residential amenity.


Retention of individual green assets is addressed in the point above. Consideration of their integration is not assessed specifically in CEEQUAL.

As above

Will the scheme extend the coverage and connectivity of the existing strategic green infrastructure network?

Whilst this issue is not considered specifically in the CEEQUAL process, it could be considered as part of the assessment of how the project has considered the wider social impacts of the completed project (Chapter 12); and improved existing wildlife habitats (Chapter 4).

As above

Biodiversity

Will the scheme be designed to maximise benefits to biodiversity, incorporating, safeguarding and enhancing natural habitats and features and adding to them where possible? Will it lead to a ‘net gain’ in biodiversity?

Biodiversity is addressed in the Ecology and Biodiversity chapter (Chapter 4). In this, CEEQUAL asks projects to assess the ecological assets of the project site, and then minimise impacts to these during construction and operation, and introduce improvements where possible. If existing ecological features on site are valuable, conservation of more than 30% of them is needed to receive credits. In case of ecological loss, credits will be given for mitigation of above 10% of the loss. Credits are given to projects that can demonstrate a net increase in wildlife habitat area relative to baseline (above 5%). Further credits are given for special structures or facilities for encouraging or accommodating appropriate wildlife.

Field surveys have been undertaken to assess the ecological assets of the scheme. The ES has assessed the potential temporary and permanent impacts (positive and negative) on the identified ecological features.

A full account of losses and mitigation measures is documented in the ES Ecology Chapter.

The mitigation measures described within the Ecology Chapter have been incorporated into the design and operational phasing of the scheme. These mitigation measures include those required to achieve the minimum standard of established best practice plus additional measures to further reduce any adverse impacts of the scheme. In addition to measures required to ameliorate negative effects on ecological features, further biodiversity enhancement measures have been identified and will be incorporated into the scheme as it is progressed.

During construction standard construction protocols will be adopted to mitigate against any potential loss of biodiversity.

Impacts to habitats of ecological value including woodland, hedgerows, species rich grassland will be compensated through provision of replacement habitats over double that which are lost. Mammal underpasses and otter ledges have been provided throughout the scheme.

Mature and veteran trees will be retained where possible. Losses will be compensated through a programme of native landscape planting (see Landscape Proposal Figures in the ES) providing approximately:

- 2 ha of native broadleaved woodland and scrub;

- 200 extra heavy standard native trees;

- 200 feathered trees.

Some potential ecological impacts from the scheme have been fully avoided through ecological input into the design development. This included realignment of the scheme between the railway and the A38 which avoided impacts to the botanically rich meadows within Colliter’s Brook Site of Nature Conservation Interest (SNCI) by making use of an existing access road to the Viridor landfill site through Hanging Hill Wood. Additionally, the scheme was realigned across Highridge Common SNCI to reduce impacts through habitat loss. Other minor scheme realignments have allowed the retention of mature trees along the route.

No net loss in biodiversity is expected based on the mitigation measures outlined in the ES Ecology Chapter.

The CEMP prepared for the scheme will capture all elements of required mitigation and present them to the appointed sub-contractor. Regular visits by an Environmental Clerk of Works will be made during the construction phase to ensure ecological mitigation is undertaken

The Bristol and North Somerset Biodiversity Action Plans should be updated and the local Biodiversity Partnerships engaged to establish a monitoring.

It is proposed that a clear target for a ‘net gain’ in biodiversity is identified and included in the CEMP.

accordingly.

A Post-construction Habitat Management and Monitoring Plan will be prepared for the Scheme to capture all the required post construction activities required to preserve and monitor biodiversity mitigation, compensation and enhancement measures (ES Ecology Chapter).

Will the scheme promote native tree planting and encourage retention of trees, with a view to enhancing biodiversity?

Retention of trees is addressed in the Landscape chapter (Chapter 3). Credits are given to projects that can retain any trees present (retention should be at least above 25% to receive credits), and if necessary adapt designs to allow for their retention. Credits are also given for planting.

Improvements in biodiversity are addressed in Chapter 4 as described above.

The scheme will promote native landscape planting, providing native broadleaved woodland planting belts, scrub and native trees. For example, the loss of approximately 0.05 ha of woodland east of the haul road will be compensated by creation of approximately 1 ha of native broadleaved woodland contiguous to the south of Hanging Hill Wood WS. Where practical, affected trees will be retained and translocated.

The created ponds will be planted with native marginal aquatic plant species (ES Ecology Chapter).

As per mitigation in the ES Chapters on Ecology and Landscape, and as outlined above.


Will it safeguard or enhance heritage assets and the character and setting of areas of acknowledged importance including Scheduled Monuments; Historic buildings both nationally and locally listed; Historic parks and gardens both nationally and locally listed; and Conservation areas?

These issues are considered within the Historic Environment chapter (Chapter 5). CEEQUAL asks that projects review all heritage assets within the project, or outside the project but may be affected; and then takes measures to ensure that they are protected during construction, and setting issues are enhanced where possible. Where restoration is required, CEEQUAL asks that appropriate materials and skilled labour are used. A mitigation strategy is required when surveys have revealed the presence of significant archaeological remains.

The ES Historic Environment Chapter identifies known heritage assets within 500m of the scheme boundary. The assessment concludes there will not be any direct adverse impact on known heritage assets recorded on the North Somerset Council or Bristol City Council Historic Environment Records.

Some slight adverse impacts are identified in the Bishopsworth & Malago Conservation Area, Castle Farmhouse and Ashton Court, Mitigation measures are proposed and a more detailed study has been carried out for the Grade 1 Listed Building Ashton Court.

As finite resources, consideration of the need to conserve individual heritage assets across the scheme has lead to a number of beneficial design changes. For example; the A38 roundabout has been relocated to avoid demolition of an important triple lime kiln structures. This will now be incorporated into the junction, which will include its restoration and future conservation. This change has been assessed as leading to a moderate beneficial effect.

Heritage assets have been mapped.


Will the scheme be carefully designed so as to protect and enhance the character, distinctiveness, diversity and quality of the landscape and townscape?

This issue is considered specifically through the Landscape chapter (Chapter 3) and generally within the Project Management chapter (Chapter 1).

If landscape and townscape character are identified as being of particular significance or sensitivity then CEEQUAL would expect them to be included as issues in the management of environmental issues in Chapter 1.

Within the Landscape chapter, CEEQUAL asks projects to ensure that landscape issues are considered at all stages of the project, and that the design fits with the local landscape/townscape character. Credits are given to projects where loss of valuable, distinctive or historic landscape features has been avoided.

The ES Landscape, Townscape and Visual Impact Assessment identified a number of short term adverse landscape and visual impacts expected to occur during construction. Furthermore, the baseline landscape elements and features will change as a result of the long term operation of the scheme.

The Landscape, Townscape and Visual Impact Assessment also documents proposed mitigation measures for four separate areas with different landscape characters.

The assessment concludes construction effects will have a minimal impact on landscape and result in minimal detraction from visual amenity of the area, therefore a slight to moderate adverse effect is expected.

During operation of the scheme the overall predicted potential effects on landscape resources and impacts on visual amenity is expected to be slight adverse to slight beneficial through the incorporation of appropriate mitigation and landscape enhancements,

Travel

Will the scheme improve accessibility within Bristol and support the proposed levels of development?

Will the scheme be part of an improved and integrated transport network and allow for a wide choice of sustainable modes of transport as a means of access to jobs, homes, services and facilities?

Travel aspects are considered within the Transport chapter (Chapter 10). Credits are given to projects that are designed to tie into existing transport links, or provide new links.

Within the Relations with the Local Community chapter (Chapter 12) CEEQUAL asks how the project has considered the wider social impacts of the completed project. Accessibility would be part of this consideration.

A Transport Assessment has been completed to document the impacts of both construction and operation of the scheme.

During construction traffic impacts are likely to involve:

- increase in traffic or congestion due to movement of works/ construction vehicles; and

- changes to pedestrian diversion routes – accessibility and severance issues particularly for children, older people and those with limited mobility, who may be particularly affected by physical or perceived severance (the EqIA).

The EqIA sets out the following mitigation: reduction of impacts through good construction practices, adequate notice or works/road signage to allow diversions and changes to access clearly signposted and be in use for the minimum possible amount of time.

The PCEMP states that a Traffic Management Plan will be produced by the PC in advance of the construction activities. This should in detail provide information about traffic and pedestrian management as well as proposed diversion and access routes. The PC in advance of the construction works should coordinate with the local authority, emergency services, public and transport organisations to minimise any negative impacts that may rise as a result of the construction activities. In addition to this, the PC should develop a Green Travel Plan to ensure a sustainable travel approach to the site is implemented. These measures include how workers travel to/ from site by the use of car sharing/ public transport and how deliveries and removal of materials and equipment to site are managed.

In terms of the operation impacts, introduction of the SBL provides a combination of improved public transport infrastructure (bus lanes on SBL and select vehicle detection at signals), new services between Bristol (city centre) and south Bristol and the airport as well as a reduction in traffic on the highway network north of SBL enabling journey times for the buses to/from south Bristol to travel marginally quicker. The analysis presented in the Transport Assessment demonstrates that the scheme improves accessibility from South Bristol to the city centre and to strategic transport links.

A foot/cycleway will run through the whole length of the SBL providing the same access as vehicles to destinations along the SBL route (The DAS).

Assessed cumulatively, the scheme has a higher mode shift potential. This is due to the addition of the enhanced Rapid Transit service from Ashton Vale to Temple Meads, which has the effect of encouraging greater mode share for Park and Ride in the morning and evening peaks (the Transport Assessment).

Will existing public rights of way be safeguarded and enhanced through incorporation into the scheme?

The SBL intersects some existing PROW between Long Ashton and the A38. The Transport Assessment identifies all PROWs in proximity to the SBL route (see section 4 of the Transport Assessment) and impacts on them. The impacts on PROW predominately occur at the western end of the route and the design has been adapted to accommodate for these. Similarly, where other footways are impacted at the eastern end of the route, provision has been made to limit the impact and to integrate these existing footways with the new provision

proposed.

The following mitigation measures are proposed;

- In proximity to the new roundabout junction, a new section of footpath will be provided connecting two existing PROW to the south of the new carriageway to reduce the need for users of these paths to cross the road. This new footway is proposed to be designated as a PROW.

- To the west of Yew Tree Farm the SBL route follows the approximate alignment of a PROW running north-to-south. This existing PROW connects to two east-to-west PROW routes to the north and south of the farm building. It is proposed to amend the north-south PROW to set it back from the SBL in proximity to Colliter’s Brook. It is proposed to accommodate this new route through the provision of un-signalised crossing points to the north and south where the route is intersected by the SBL carriageway.

Will construction traffic effects be minimised?

CEEQUAL requires that Construction Traffic Management Plan or a transport section aims to minimise disruption caused by construction traffic.

See above.


Is community consultation being undertaken as part of the development of the scheme design?

Community consultation is considered through the Relations with the Local Community and Other Stakeholders chapter (Chapter 12). CEEQUAL asks for a community consultation process to be undertaken through the lifetime of the project with consultation undertaken by the client, design team and contractor.

The NSC and BCC Councils consulted widely in 2008 and 2009 on the principles, options for the alignment of the route corridor and Scheme outline. Prior to the planning application submission, a further public consultation was undertaken in May and June 2012, focussing on the South Bristol Link scheme layout. The responses prompted a thorough design review process from July 2012 to March 2013, informed by ongoing stakeholder engagement, with further options appraised to determine the final proposed alignment and scheme design which form the basis of the current application.

A report on the consultation will be submitted with the planning application.

Focused consultation has been undertaken and information provided to a number of groups including but not limited to:

- Statutory consultees (Environment Agency, English Heritage and Natural England)

- Non-motorised users groups (NMUs)

- Local businesses

- Local residents

- Statutory Utility companies

The results of this stakeholder engagement are tracked on a Consultation Tracker.

No further recommendations

Will the scheme contribute to enhancing existing or developing new public realm that enables people to gain access safely and conveniently, particularly serving the needs of pedestrians, cyclists, children, and the disabled and older people?

CEEQUAL asks specifically how the health and welfare of occupants, users, neighbours and/or any operational staff have been considered, and the design modified as a result; and that the needs of all different user groups have been considered and respected in the design solution (for example, car drivers, cyclists, pedestrians, disabled people etc) and the specification achieved in the completed project?

As described in the DAS the SBL will provide an alternative route to destinations avoiding the smaller urban streets. The landscaping and footways in the reserved corridor in Bishopsworth will make the area more aesthetically pleasing and provide pupils with a walking route to the school.

A foot/cycleway runs the whole length of the SBL providing the same access as vehicles to the destinations along the SBL route.

Pedestrian and cycle movements are catered for at all of the signalised junctions along the route. The new shared foot/cycleway will provide access to the countryside to families and people less able to use the current paths (the DAS).

Improved accessibility from South Bristol to the city centre and strategic transport links will benefit deprived/unemployed residents and households without a car (improvement in access to employment and education centres); disabled and older people for access to South

Bristol hospital. Low floor buses are a use requirement of the scheme (the EqIA).

Will the scheme be designed for low traffic speeds in particular in residential and retail areas and when it serves as a route to schools?

This aspect is not considered specifically in CEEQUAL.

The route is designed for a number of users, primarily vehicles; there will be a segregated bus lane part of the way, as well as a

route for cyclists and pedestrians. The speed limit enforced on the road will be 30mph throughout the urban areas (Cater road roundabout, reserved corridor, King Georges road, Highridge common). Between Highridge common and the A38 roundabout the speed limit will increase from 30 to 40mph. The 40mph limit then applies to the remainder of the SBL and all approaches from existing roads (A38 and A370) to the new roundabouts.

Will the scheme take account of personal safety, security and crime prevention?

This is not considered specifically in CEEQUAL, apart from the health and welfare aspect discussed above.

During construction an increase in traffic or congestion due to movement of works / construction vehicles may have safety and security impacts on local people, in particular, children due to inexperience when travelling, and older and disabled people due to perceived safety and severance issues (SBL Equality Impact Assessment (EqIA)).

The EqIA recommends that reduction of impacts is achieved through good construction practices and adequate notice or works/road signage to allow diversions.

A foot/cycleway will run through the whole length of the SBL providing the same access as vehicles to destinations along the SBL route. The provision of appropriate infrastructure for cycling and walking is likely to help create the feelings of personal safety and security (refer Stage 1 Safety Audit which has been completed for the scheme).

A New Approach To Appraisal (NATA) of the scheme, which aims to appraise and inform the prioritisation of transport investment proposals, indicated slight positive impact on health from the scheme due to increased provision for walking and cycling. Overall the scheme was also deemed to provide a moderate positive impact on safety.

The traffic management measures include speed restrictions of 30mph throughout the urban areas.

The scheme is also anticipated to bring moderate beneficial impact to journey ambience due to cleaner route.

On the other hand, some groups may feel a perceived safety risk waiting for, and using, public transport. The EqIA mitigation includes the provision of ‘Safe haven’ shelters with improved lighting and RTPI and CCTV in buses to aid safety and security.

As identified in the EqIA and Socio-Economic ES Chapter.

Please also refer to Hillier and Sahbaz (2009) Crime and Urban Design: An Evidence Based Approach.

Will public art be part of the

scheme, if appropriate? This aspect is not considered specifically in CEEQUAL. This aspect is not covered in the scheme documentation.

In terms of likely cumulative effects, the SBL, as part of the proposed Rapid Transit network, is likely to lead to improved image and perception of the area along the route, increase land values along the route corridor and offer the chance for a step change in development quantum and mix if the locations are seen as attractive to commercial and residential developers. The proposed SBL should lead to improved accessibility to public transport for residents in south Bristol and associated improved links to Bristol City Centre. As one of the three proposed rapid transit schemes, SBL has the potential to contribute towards very significant economic growth and development (see the findings above and the Socio-Economic Assessment in the ES).

SBL ES: 2.1

South Bristol Link: Environmental Statement Volume 2: Introduction & Methodology, June 2013

1.5. Conclusions

1.5.1. This Sustainability Statement forms part of the planning application for the SBL scheme. It has assessed the scheme against the appropriate sustainability framework. The sustainability framework comprises a list of relevant sustainability topics and decision-making questions and considerations for each topic. The framework was developed to ensure a common approach has been employed for the preparation of the Sustainability Statement for the SBL and NFH rapid transit routes across the City of Bristol. The development of the common sustainability framework took into account relevant national and local policy documents for each of the three local authorities including BCC, NSC and SGC. Additionally, CEEQUAL topics and decision-making questions have been considered to complement the coverage of local authority policies. This was achieved by completing a screening exercise of CEEQUAL topics and questions to identify those that are applicable at the planning application stage.

1.5.2. The sustainability framework was circulated to the EIA specialists and other project stakeholders at the scoping stage to inform their work early in the project process. Subsequently, the specialists provided inputs into the sustainability assessment process to indicate how sustainability considerations have been taken on board. These inputs and findings of the Sustainability Statement indicate that consideration has been given to sustainability aspects as part of the scheme design.

1.5.3. In particular, the scheme delivers positive performance in relation to the following topics:

Transport/ accessibility – the SBL provides a combination of improved public transport

infrastructure (bus lanes on SBL and select vehicle detection at signals), new services

between Bristol (city centre) and south Bristol and the airport as well as a reduction in traffic

on the highway network north of SBL enabling journey times for the buses to/from south

Bristol to travel marginally quicker. A foot and cycleway will run through the whole length of

the SBL providing the same access as vehicles to destinations along the SBL route. The

scheme’s potential to contribute to a mode shift is greater when considered in combination

with the other rapid transit links.

Low floor buses are a requirement of the scheme.

Safety – the traffic management measures include speed restrictions of 30mph throughout

the urban areas.

Waste, recycling and re-use of resources – the scheme’s SWMP includes a list of waste

prevention and waste minimisation measures such as optimisation of alignment to minimise

impact on undisturbed ground, to optimise cut and fill volumes and re-use excavated topsoil

on site.

Soil – the quality and quantity of soil on site would be maintained by implementing

appropriate techniques for stripping, storing and re-use. A Soil Handling and Management

Strategy will be included within the CEMP with a view to protecting soils, managing and

reducing the risk of soil erosion.

Materials – a Materials Management Plan will be prepared to manage and control the import

of fill materials and appropriate reuse of excavated material within the scheme.

Flood risk – the scheme has a good level of protection against flooding. The Flood Risk

Assessment allowed for climate change impacts.

Water – overall the scheme will deliver positive effects on the water quality due to the

incorporation of additional mitigation measures, e.g. detention basins (to retain and treat the

most polluted water from the rainfall runoff) and attenuation tanks (both surface and

underground). Where practicable, grey water systems would be used at site compounds to

reduce run-off from site, improve water efficiency and lessen the potential for polluting

discharges.

Ecology and landscape – new ecological features and landscaping will be incorporated in the

scheme’s design partially to compensate for the losses of some ecological habitats and

features, but also in order to enhance the local biodiversity and visual amenity.

1.5.4. Potential negative effects may arise in relation to noise levels (both during construction and operation), air quality during the construction, scheme’s lighting, loss of some ecological habitats

and features, the character of the Bishopsworth and Malago Conservation Area, visual amenity, construction traffic impacts and increased materials and energy use.

1.5.5. The mitigation measures for these effects have been set out in the ES and other relevant project reports. Additional recommendations proposed in this Statement include the following:

Noise – it is recommended that mitigation measures should include considerations for

source control, path control and receptor control, selecting most efficient and practicable

measures.

Waste – it is recommended the SWMP KPI adopt ambitious targets.

Ecology/ green infrastructure – The Bristol and North Somerset Biodiversity Action Plans

should be updated and the local Biodiversity Partnerships engaged to establish a monitoring.

It is proposed that a clear target for a ‘net gain’ in biodiversity is identified and included in the

CEMP.

Materials use – A life cycle assessment of the key materials and components used should

be undertaken at the next planning stage. It is recommended to consider use of BES6001

Framework Standard for the Responsible Sourcing of Construction Products (Oct 2008), and

BS 8902:2009 – Responsible sourcing sector certification schemes for construction products

– Specification.

Water – The PCEMP should identify the need for minimising water consumption in

construction and stipulate that this aspect should be covered in the CEMP.

Energy – It is recommended that the CEMP should identify opportunities for reducing energy

use and energy efficiency throughout the project cycle. Set ambitious emissions reduction

targets for each stage. Consider opportunities for renewable and low carbon energy

technologies to meet the projected overall energy use (embodied and in use). Calculate life

cycle energy use and set project baseline. This can be combined with the life cycle

assessment of materials.

1.5.6. The incorporation of the proposed mitigation measures in the scheme’s design will enhance the scheme’s sustainability performance and will help achieve the CEEQUAL ‘Very Good’ or ‘Excellent’ rating as expected.
