1. KEY MESSAGES

1.1 What is this report?

• The Runnymede Local Plan is being subject to a Sustainability Appraisal (SA) to assess its effects on important sustainability issues within the Borough.

• This report sets out an assessment of the Runnymede Issues, Options and Preferred Approaches document (July 2016). The results of this assessment will be used by the Council when drafting the next stages of the Local Plan.

1.2 What has been assessed?

• As part of the SA process reasonable alternatives need to be defined and assessed. This includes defining and assessing reasonable alternative sites for development and reasonable alternative approaches to the spatial strategy and other planning issues.

• There is no generally accepted definition of what constitutes reasonable and it is up to the Council to decide what is reasonable.

• All of the sites that are deemed reasonable by the Council have been assessed. Appendix 1 sets out which sites are considered reasonable and why.

• The Council has also developed a number of alternatives approaches to planning issues (spatial strategy; housing; economy and retail; built environment; natural environment; recreation, green space and leisure; heritage; transport and infrastructure; and flooding). The reasoning behind the choice of reasonable alternatives for these issues is also set out in Appendix 1;

• The approach to the assessment of the alternative approaches has been set out in sections 3.1 to 3.9 in this report. Not all approaches have been assessed or assessed against the full range of sustainability topics. This is because they will have effects on only some of the sustainability issues or because alternatives have not been suggested (and the purpose of this stage of the assessment is to help the council decide between alternatives).

1.3 What were the results?

• The results of the assessments are shown in assessment tables which show how each site / alternative approach performs in relation to different sustainability objectives.

• Significant negative effects are shown in red and significant positive effects are shown in green.

• A significant negative effect does not mean that a particular site / approach should not be taken forward by the Council and a significant positive effect does not mean that the site / approach should automatically be taken forward.

• The results of the site assessments are shown in Appendix 2 and a summary is included in section 4.1. Generally, the preferred sites performed comparatively well (compared to the alternative sites suggested). In particular the preferred sites performed comparatively well in relation to Green Belt issues as the preferred sites are either Residual Land Parcels (where development has been shown to be more acceptable to Green Belt purposes); or are within settlement limits and are designated as housing reserve sites in the Runnymede Local Plan 2001 (as saved) and as such would be considered suitable for residential development. In some cases the preferred sites will have potentially negative or uncertain effects on the SA objectives and these are outlined in Appendix 2.

• The results of the assessment of the alternative approaches is shown in Section 4. Generally, the Council’s preferred approaches have performed comparatively well. However, in some

SUSTAINABILITY APPRAISAL OF THE ISSUES AND OPTIONS

2

cases the preferred approaches will have potentially negative or uncertain effects on the SA objectives and these are outlined in Section 4.

• The Council can use the results of the assessment to choose planning approaches and a portfolio of sites that performs the most positively, and can use the knowledge gained to ensure that mitigation measures are put in place to reduce any negative impacts identified.

• For more detail on the performance of a particular site / approach please see Appendix 2 (for site assessments) and Section 4 (for the assessment of potential approaches).

2. INTRODUCTION

2.1 Background

The preparation of the Runnymede 2035 Local Plan is being subject to an integrated sustainabil-ity appraisal (SA) and strategic environmental assessment (SEA) in line with the requirements of Statutory Instrument 2004 No. 1633: The Environmental Assessment of Plans and Programmes Regulations 2004 (the SEA Regulations). In English planning practice this combined assessment is referred to as a Sustainability Appraisal (SA). The SA is being carried out by Ramboll Environ using a team of consultants experienced in strategic appraisal of local authority spatial planning documents. The purpose of the SA is to promote sustainable development by integrating sustain-ability considerations into the plan making process at all relevant stages including when consider-ing alternative approaches to developing the plan (the issues and options stage).

2.2 This report

This document presents the findings of the SA of the Runnymede 2035 Local Plan, Issues, Op-tions and Preferred Approaches document (July, 2016). The information in this report will be used by the Council when drafting the next stages of the Local Plan.

This report does not constitute an environmental report (in the English planning system called a SA report) under the SEA regulations. At the issues and options stage it is good practice to pro-duce fairly brief reports which can then be developed into the formal (regulation compliant) SA report at a draft plan stage. Please also note that further assessment of alternatives is also likely to be carried out as part of the assessment of the draft plan.

2.3 Habitat Regulations Assessment

Please note that this report does not constitute a Habitat Regulations Assessment (HRA) screen-ing report. A HRA screening report has been produced1 and has concluded that there will be no adverse effects to Thursley, Ash, Pirbright & Chobham SAC, Windsor Forest and Great Park SPA and the South West London Waterbodies SPA/Ramsar (one unit Thorpe Gravel Pits 1 and sup-porting habitats).IN relation to the Thames Basin Heaths SPA and SANG provision it is considered that there would be no risk of an adverse effect on the Thames Basin Heaths SPA since the policy developed under Preferred Approach NE2 would require the Council to either meet the SANGS provision from alternative strategic SANGS, meet the shortfall by releasing development sites that can provide their own SANGS, or revise its overall housing allocation to reflect that for which SANGS could definitely be provided. Therefore it can be concluded that there will be no adverse effects to Thames Basin Heaths SPA.

2.4 Stages of the SA

There are a number of stages to SA and these are shown below:

Completed stages: An SA scoping report was produced in September 2014. From all of the infor-mation collected, an SA framework, or set of sustainability objectives, was developed, against which the various components of the plans will be appraised. This SA framework has been amended taking into account the views of consultees;

• This stage: The production of an issues and options assessment briefing paper (this report) which outlines the results of the SA of the ‘Runnymede 2035’ Local Plan (formal Regulation 18 consultation);

• Future stages: The appraisal of the draft plan (likely to be later in 2016) and amendments to the SA to take into account the results of consultation (likely to be early 2017).

2.5 ‘Runnymede 2035’ Local Plan

The Borough Council’s current Local Plan – The Runnymede Local Plan (Second Alteration) was adopted in 2001. The Council is now required to produce a new Local Plan by early 2017, which will plan for and manage development up to 2035.

It is being prepared to help further guide planning decisions in the area and once adopted, will contain all policies (both strategic policies and more detailed Development Management level po-lices), and all land use allocations necessary to guide development in the Borough up to 2035. On adoption, it is intended that the plan will replace the remaining saved policies of the 2001 Runnymede Borough Local Plan.

The Issues and Options consultation is the early part of the Local Plan making process and sets out the issues that are facing Runnymede over the next 20 years, the potential options for deal-ing with those issues and based on those considerations, what the Council thinks the preferred strategy should be in each case. The consultation fulfils the requirements of Regulation 18 of the Local Planning Regulations 2012.

2.6 How to comment on the report

This report is being published for consultation and we would welcome comments on the method-ology used and results of the assessment.

This statutory consultation is open until Wednesday 17th August. We are unable to accept anony-mous representations and representations must be made in writing. We would like you to send us your views electronically if possible. You can complete the questionnaire on our website or down-load a copy of the questionnaire to complete and email back to us at [email protected]. If you cannot do this, please request and return a printed copy of the questionnaire to us. Please clearly mark any additional sheets with your name and ensure that you confirm which part of the document you are referring to. Please send your completed questionnaire to: The Policy and Strategy team, Runnymede Borough Council, Civic Centre, Station Road, Addlestone, KT15 2AH.’

2.7 Next steps in the process

The next step in the preparation of the Local Plan for Runnymede Borough will be the preparation of a draft plan. This is currently scheduled to be produced later in 2016. At this point in the pro-cess the formal SA report will be produced and will be consulted on with the public and other stakeholders at the same time as the draft plan.

3. METHODOLOGY OF THE ISSUES AND OPTIONS ASSESS-MENT PROCESS

3.1 Introduction

This stage involves appraisal of the issues and options against the SA framework, taking into ac-count the evidence base. The SEA Regulations make it clear that reasonable alternatives to a plan should be identified and assessed. In addition to this, the SA report should include an out-line of the reasons for “selecting the alternatives dealt with” (SCHEDULE 2, Regulation 12(3)).

3.2 Selecting / identifying reasonable alternatives

The SEA Regulations require that the SA report identifies the reasons for selecting the alterna-tives tested in light of the others available (SEA Regulations Schedule 2 (8)). In SA practice this is usually understood as having two meanings:

1. Discuss why it was ‘reasonable’ to select the alternatives that were developed to be tested; and

2. Discuss why the preferred approach was selected in light of the SA of alternatives.

There is no generally accepted definition of what constitutes reasonable and it is up to the Coun-cil to decide what sites and strategy approaches are reasonable. In the interests of putting in place a clear audit trail for the SA, Appendix 1 outlines in detail why reasonable alternatives were selected by the Council (both for sites and the strategic approaches considered).

3.3 Assessing reasonable alternatives

3.3.1 What has been assessed?

Both site allocations and strategic issues / alternative approaches have been assessed. All the sites that have been defined as reasonable (as highlighted above and discussed in Appendix 1) have been assessed.

However, the information presented by the Council in the Issues, Options and Preferred Ap-proaches consultation document is more than just potential development sites. It is a mix of op-tions, potential approaches and sites. Sites can be assessed against the SA framework with a higher level of certainty compared with the more generic potential approaches. It is not possible or useful to assess the effects of potential approaches against every element of the SA frame-work, either because they will have effects on only some of the sustainability objectives or be-cause alternatives have not been suggested (and the purpose of this stage of the assessment is to help the council determine between alternatives). It is important that the SA process is fo-cused on where it can make a positive difference and add value to the decision making process (which at this stage is focused on choosing between alternatives). Therefore each potential ap-proach has been assessed slightly differently and some of them have not been assessed. How-ever, please note that all policies developed as part of the Draft Plan will be assessed as part of the next stage of the SA. To determine whether the approaches are likely to have an effect on the SA objectives (and therefore whether an assessment is needed), a screening table has been used. This is shown in Annex A of this report. Please also see Section 4 which sets out the way that each approach has been assessed.

3.3.2 How is sustainability defined?

The scoping stage of the SA (as referred to in Section 1.3) resulted in the production of a SA framework which will be used to test the sustainability of the plan. This is shown in Table 2.1. The SA framework sets out those factors that are considered to be important in defining and test-ing sustainability for this plan. Some amendments were made to the SA framework following consultation in 2014 and these changes have been shown in grey highlighting.

Please note that the SA makes an assessment against the future baseline (or a without the plan scenario). In such a scenario development is still likely to take place but without the benefit of Local Plan policies guiding it in a more sustainable direction. In addition, the SA objectives are geared towards helping the Council steer development away from sensitive areas and promote development that is more sustainable. This means that promoting development will not neces-sarily score negatively. For example for a site that avoids designated ecological sites it is per-fectly possible for this site / strategy to score positively with regard to SA objective 1 (biodiver-sity).

Table 3.1: Proposed SA framework

Table 3.1: Proposed SA framework

Proposed SA Objectives Proposed decision-aiding criteria

SA Objective 1: To conserve and enhance biodiversity, habitats and species

Will it avoid potential impacts of development on designated sites? Will it avoid net loss of and achieve enhancement of ecological resources and services? Will it avoid habitat fragmentation? Will it lead to development which incorporates biodiversity into the design e.g. linking green corridors, incorporation of habitats etc helping to reduce the future effects of climate change on biodiversity?

SA Objective 2: to protect and improve the health and well-be-ing of the population and reduce inequalities in health

Will it help to address pockets of deprivation and child poverty? Will it improve access to healthcare? Will it provide for the needs of an ageing population? Will it facilitate active lifestyles? Support local sustainable food production, including the provision of allotments and community gardening?

SA Objective 3: to protect soil and minerals resources

SA Objective 6: to reduce air and noise pollution

Will it ensure that development minimises exposure to poor air quality and noise pollution? Will it avoid contributing to congestion? Will it facilitate the incorporation of electric vehicle charging points into new developments or ensuring they can be retrofitted?

SA Objective 7: reduce green-house gas emissions

Will it ensure that new developments are designed to achieve high levels of energy efficiency? Will it prioritise access to good public transport and safe walking and cycling facilities infrastructure (including segregated cycle lanes), over facilities for private cars? Will it increase renewable energy generation? Will it achieve development that demonstrates sustainable design and construction including efficient use of materials?

Will it support a dynamic and diverse economy including a dynamic rural economy? Will it stimulate economic growth in deprived areas? Will it support all businesses and business sectors and low environmental impact business sectors in particular? Will it contribute to the provision of opportunities for employment and improvements in educational attainment and skills development?

SA Objective 9: to ensure the provision of high quality, sus-tainable constructed and afforda-ble homes and necessary com-munity infrastructure.

Will it provide viable and deliverable good quality and affordable housing to meet identified needs? Will it ensure the delivery of necessary community infrastructure and access to a full range of community services?

SA Objective 10: to protect and enhance the Borough’s historic assets

Will it ensure that development avoids adverse effects on heritage assets, archaeology and Conservation Areas? Will it ensure that development is well-designed and is well- related to the surrounding townscape?

SA Objective 11: to protect and enhance open space and the landscape character of the Bor-ough

Will it protect and enhance landscape character? Will it ensure the quality of and provision of suitable open space, where need is identified?

3.3.3 How does the SA define significance

As part of the SA it is necessary to outline likely significant effects. To do this in as clear and transparent way as possible, a set of significance criteria has been defined for the assessment and every impact has been scored accordingly. The significance criteria that have been used are set out in Table 2.2.

Table 3.2: Significance criteria

Table 3.2: Significance criteria

Score Description Symbol

Significant positive impact The option strongly supports the achievement of the SA Objective and has a major positive effect with relation to characteristics of the effect and the sensitivity of the receptors

++

Minor positive impact The option generally supports the achievement of the SA Objective and has a minor positive effect with relation to characteristics of the effect and the sensitivity of the receptors

+

Neutral The option does not have an effect on the achievement of the SA Objective

0

Minor negative impact The option conflicts with the achievement of the SA Objective and has a negative effect with relation to characteristics of the effect and the sensitivity of the receptors

-

Significant negative impact The option conflicts with the SA Objective and has a negative effect with relation to characteristics of the effect and the sensitivity of the receptors. In addition the future baseline indicates a worsening trend in the absence of intervention

- -

Uncertain It is unclear whether there is the potential for a negative or positive effect on the SA Objective

?

3.3.4 Cumulative effects

To comply with the SEA regulations it is necessary to identify any likely significant cumulative ef-fects of the plan. A detailed cumulative effects assessment will be carried out at the draft plan stage and reported as part of the formal SA report.

3.3.5 Difficulties encountered in the assessment

The main difficulty encountered in the assessment was the lack of detail apparent in the potential approaches (please note that at this stage in the planning process it is entirely expected that the alternative approaches do not contain detailed expression) which leads to a fairly broad brush as-sessment of this element of the issues and options assessment. This was dealt with by focusing the assessment on providing a general indication of the relative performance of the potential ap-proaches.

4. ASSESSMENT RESULTS

4.1 Introduction

The results of the site assessments are shown in Appendix 2. The results have been presented in assessment tables, which enables readers to clearly see performance against the SA objectives.

The key constraints within the District are Green Belt, flooding and biodiversity (with regard to the effect of Natura 2000 sites and other issues). With regard to Green Belt issues the preferred sites are either Residual Land Parcels (where development has been shown to be more accepta-ble to Green Belt purposes); or are within settlement limits and are designated as housing re-serve sites in the Runnymede Local Plan 2001 (as saved) and as such would be considered suita-ble for residential development. Other alternative sites have performed less well as they are within the Green Belt and the sites are not considered to be (or totally to be) previously devel-oped land. This would mean that development would be unacceptable to Green Belt purposes and would require a review of the Green Belt boundary to allow development to go ahead.

With regard to flooding, large areas of the Borough are subject to flood risk. However, all of the sites generally performed well with the majority in flood zone 1. The preferred sites also gener-ally performed well, with the majority of the sites being in flood zone 1. Three of the preferred sites (60, 255 and 256) are partly within flood zones 2 and 3. With sites 255 and 256 this is fairly minor areas of land. Larger parts of Site 60 is partially in zones 2, 3a and 3b. Flood zone 3b is an absolute constraint so this section would be left undeveloped and any development within zone 2 would need to pass the sequential test and if in zone 3a both the sequential and exception tests.

With regard to the impact on Natura 2000 sites one of the key issues is the effect on the Thames Basin Heaths Special Protection Area (TBHSPA). Many of the sites assessed (including the major-ity of the preferred sites) are within the 5km buffer zone of the TBHSPA meaning that Suitable Accessible Natural Greenspace (SANGs) would need to be provided if development were to go ahead.

SA relies on expert judgement, which is guided by knowledge of the likely effects of the plan, the baseline data available and responses and information provided by consultees and other stake-holders. A ‘precautionary approach’ is taken with the worst case scenario being reported in the case of any doubt about potential effects, and mitigation is suggested if there is any doubt as to the effect of the plan.

The assessment of the potential approaches is reported in this section of the report. The assess-ment results are set out in assessment tables showing the performance of the approaches against the relevant SA objectives. Please note that the Council’s preferred approach is high-lighted in grey in the tables. Due to the high level nature of the assessment at this stage mitiga-tion measures and enhancement measures have not been explicitly included in the tables. How-ever, some recommendations are given throughout the assessment of issues that need to be considered as policies are drafted.

The Council’s preferred approaches perform comparatively well (compared with the alternative approaches posed). However, there are some uncertain / negative effects recorded in relation to some of the preferred approaches as listed below:

• Spatial strategy approach SS3 (deliver development in urban areas and on previously developed sites in the Green Belt. Return Thorpe to settlement and release some of the Resultant Land Parcels). There are uncertainties attached to all of the spatial strategy approaches because of their high level nature. SS3 has an uncertain / minor negative effect against SA objective 1 (biodiversity), objective 3 (soil and minerals) and objective 11 (landscape character). It has an uncertain effect against objective 4 (water), objective 9 (provision of homes) and objective 10 (historic assets). Minor negative effects have been recorded against objective 5 (climate and flood risk) and objective 8 (economic growth). A

SUSTAINABILITY APPRAISAL OF THE ISSUES AND OPTIONS

10

mixed effect of uncertain/ minor positive has been recorded against SA objective 6 (air and noise) and objective 7 (greenhouse gas emissions) and a minor positive effect has been recorded against objective 2 (health and well-being). However, the preferred strategy performs well in comparison with the other strategies and it is felt that the preferred strategy is the most positive as it will focus as much development as can be sustainably managed in the Borough through a focus on development in urban areas, previously developed sites in the Green Belt and RLPs. Unsurprisingly the main tension is between the provision of homes and protecting the landscape character and Green Belt of the Borough with strategies that provide for a higher percentage of the OAN (SS5 - 7) scoring well against objective 9 (provision of homes) and poorly against objective 11 (landscape character). Strategies that provide for a lower percentage of OAN (SS1 – SS4) score less well against objective 9 (provision of homes) but potentially slightly better with regard to objective 11 (landscape character) (although it needs to be recognised that this unmet need will have to be met in neighbouring authorities which have similar constraints to development). Once it is clearer where any unmet need is likely to be located further work should be undertaken to understand its sustainability implications working in conjunction with neighbouring authorities.

• TH1-TH6 (Thorpe Boundary Options) have the potential to cause some negative effects if the changes in the village boundary led to development. However, the inclusion of an area as part of a boundary option does not mean that it has been allocated for development and an assumption cannot be made that development will occur on these areas in the foreseeable future;

• H2/01 (Minimum density policy, with bespoke densities in certain areas, i.e. ‘commuter hubs’ in line with developing Government policy) and BE1/01 (Include an overarching policy approach to enhancing Runnymede’s townscape and public realm including density guides) could lead to an uncertain effect on townscape character. The approach could lead to development which is of a higher density than the surrounding area, therefore, risking negative effects on this aspect of townscape. The Local Plan will need to ensure that high quality design is a key part of policy, taking into account aspects of the Runnymede Urban Character Appraisal;

• H4/03 (Meet the need for specialist accommodation in full – look at existing sites and make up the shortfall within the Resultant Land Parcels (at the expense of general housing)) will be positive with regard to meeting the needs of specialist populations but uncertain with regard to the effect on general affordability. There is a risk that this is done at the expense of general affordable housing and the correct balance will need to be struck as the approach is developed;

• F3/01 (To allow applicants an automatic pass of the sequential test for applications in flood zones 2 and 3a where sites are otherwise shown to be available, suitable (in Runnymede this would be sites put forward for development in the Urban Area or on previously developed land in the Green Belt) and achievable for development) could increase the risk of more people and businesses being affected by flooding. However, the Council has stated that it will remain committed to ensuring that sites proposed would continue to be safe in a flood event. Until further details are known this has been listed as a minor negative effect.

• F3/01 (see above) would help the Council meet the need for significantly increased housing supply and provision of more employment land. However, an uncertain effect has also been noted against SA objective 8 (sustain economic growth) as the cost to businesses of flooding is uncertain.

• There is not enough evidence to show what the effects of F4/02 (Do not issue article 4 directions to remove permitted development rights for minor extensions) would be, therefore

SUSTAINABILITY APPRAISAL OF THE ISSUES AND OPTIONS

11

an uncertain effect has been given. Further research is needed to ascertain the cumulative impact of minor developments on the flood risk.

4.2 Spatial strategy

4.2.1 What has been assessed?

All of the alternative approaches have been assessed against the SA framework, albeit to a high level of detail. This is because at the spatial strategy level there is (as would be expected at this early stage in strategy development) little detail presented on potential locations of development (especially for options SS5, SS6 and SS7 – where additional Green Belt land may be released in currently unknown locations). The proposed vision and objectives of the plan have also been assessed and are included in the table below. Please see Appendix 1 for an explanation of the content of each alternative.

4.2.2 The results of the assessment

+ ?/- ?/- ?/- ?/- ?/- ?/- ?/- The vision and objectives score positively. The amount of land required within the Borough would increase from options SS1 to SS6, with the least amount of land within the Borough required for Option SS1 (but higher amounts of land required outside of the Borough – see below). All the options would focus development on urban areas and previously developed sites (meaning less risk to ecologically sensitive sites in the Borough). Options SS3 and SS4 would also utilise some of the Resultant Land Parcels (RLPs) which have some ecological sensitivities and options SS5, SS6 and SS7 would utilise the RLPs and increasing amounts of additional Green Belt land (in unknown locations). However, it must be recognised that any unmet housing need would have to be sought in neighbouring authority areas following Duty to Co-operate discussions and there is a risk that agreement to take unmet needs will not be met. If some of the Borough’s needs are accommodated in neighbouring authorities, this could potentially cause ecological

SUSTAINABILITY APPRAISAL OF THE ISSUES AND OPTIONS

13

issues wherever development takes place (and all neighbouring authorities are similarly constrained). However, the potential locations of this development are an unknown. All of the approaches would require the provision of additional Suitable Alternative Natural Greenspace (SANGS) solutions. Some of the options (Option SS2, SS3, SS5, SS6 and SS7) would return Thorpe to settlement but this is only likely to result in a small number (less than 5 per annum) new houses so this is not seen as a significant issue (please also see the assessment of the Thorpe Boundary options). In conclusion, the effects of all of the approaches have some level of uncertainty attached to them but with the potential to score negatively. However, it is felt that the preferred strategy is the most positive as it will focus as much development as can be sustainably managed in the Borough through a focus on development in urban areas, previously developed sites in the Green Belt and RLPs.

SA Objective 2: To protect and improve the health and well-be-ing of the population and reduce inequalities in health

+ - - + + +/- +/- +/- The vision and objectives score positively. The higher the level of objectively assessed need (OAN) that can be met within the Borough the more positive the strategy will be for access to services as people will be able to access the services they need in a more sustainable way and the higher the level of development the more viable services will be within the Borough. Please see the assessment against SA9 for a more detailed discussion on OAN. However, the higher the level of development within the Borough the more green space is likely to be developed on with potential secondary effects on people’s health and well-being. On balance it is felt that the preferred approach is the most positive as it can meet up to 82% of the OAN but will not result in additional development on Green Belt land (additional to the RLPs).

potentially conflict with mineral development. Please also see assessment against SA objective 1 in relation to development outside of the Borough and the fact that all of council areas around Runnymede are similarly constrained. Whether development minimises waste arisings and facilitates recycling (a SA sub objective of objective 3) is dependent on how development is implemented so this is unclear at this stage. In conclusion, the effects of all of the approaches have some level of uncertainty attached to them but with the potential to score negatively. However, it is felt that the preferred strategy is the most positive as it will focus as much development as can be sustainably managed in the Borough through a focus on development in urban areas, previously developed sites in the Green Belt and RLPs.

SA Objective 4: to improve water quality and efficiency?

+ ? ? ? ? ? ? ? The vision and objectives score positively. This is dependent on how development is implemented, therefore the effects are uncertain at this stage. However, it should be recognised that effects on issues such as water use within the Borough will increase as the housing numbers increase. However, it must be recognised that any unmet housing need would have to be sought in neighbouring authority areas following Duty to Co-operate discussions and there is a risk that agreement to take unmet needs will not be met. If some of the Borough’s needs are accommodated in neighbouring authorities, water use will increase in line with the quantum of development. Policies within the Local Plan on sustainable construction are likely to mitigate these effects but this will be assessed and reported in the formal SA report.

SA Objective 5: to increase resili-ence to climate change, including flood risk

+ - - - - - - - The vision and objectives score positively. Whether development incorporates SUDS and are more resilient to climate change (SA sub objectives of objective 5) is dependent on how development is implemented so this is unclear at this stage. With regard to directing development towards areas with the least flood risk, all of the approaches would pose a risk that properties are subject to flood risk as the large parts of the Borough’s urban areas (especially Chertsey and Egham) are subject to high risks of flooding. There is also a likelihood that SS5, SS6 and SS7 (which would

SUSTAINABILITY APPRAISAL OF THE ISSUES AND OPTIONS

15

increase levels of development in the Green Belt in unknown locations) would result in development in areas at risk from flooding. However, adjacent authorities are also subject to similar levels of flood risk (this area of the country is the largest area of undefended floodplain in England) so in SS1 and SS2 which meet very low levels of the OAN there would also be a risk. In conclusion, the effects of all of the approaches have some level of uncertainty attached to them but it is felt that the preferred strategy is the most positive as it will focus as much development as can be sustainably managed in the Borough through a focus on development in urban areas, previously developed sites in the Green Belt and RLPs (and in generally low risk flood areas).

SA Objective 6: to reduce air and noise pollution

+ +/? +/? +/? +/? +/? +/? +/? The vision and objectives score positively. All of the strategy approaches will be positive in that they will focus development in the urban areas and / or in the RLPs, most of which lie adjacent to the existing urban areas and mainly those which sit higher in the centres hierarchy (or in the case of Longcross can be made to be self-sustaining). This will be positive in relation to facilitating more sustainable forms of transport and reducing the need to travel which will have secondary positive effects in relation to air and noise pollution. There is a possibility that SS5, SS6 and SS7 (which would increase levels of development in the Green Belt in unknown locations) could increase the need to travel. However, options which would seek higher levels of OAN outside the Borough are also likely to be located in areas which would do the same. Development in the urban areas and RLPs could also be subject to air and noise pollution and this would affect all the potential approaches. In conclusion, the effects of all of the approaches have some level of uncertainty attached to them but it is felt that the preferred strategy is the most positive as it will focus as much development as can be sustainably managed in the Borough through a focus on development in urban areas, previously developed sites in the Green Belt and RLPs.

SA Objective 8: to sustain eco-nomic growth and competitive-ness across the Borough

+ - - - - - - - The vision and objectives score positively. SS1 would lead to a deficit of up to 41,000sqm industrial floorspace, specifically for storage and distribution uses.

There may be opportunities to deliver mixed use developments at some of the RLPs which could incorporate an element of storage & distribution if suitable and viable for this use, but it is likely that Runnymede will not be able to meet its employment needs under any of the scenario’s. The ability of Runnymede to deliver its employments needs will be dependent on neighbouring authorities in the FEA and there is a risk that agreement to take unmet employment needs will not be reached. All of the options are therefore negative in this regard.

Whether development achieves the delivery of necessary infrastructure and access to services (an SA sub objective of objective 9) is dependent on how development is implemented so this is unclear at this stage. With regard to meeting identified need for housing, the following figures are relevant. SS1 – level of unmet need would be between 286 to 385 dwellings per year; SS2 - 283 to 383 dwellings per year; SS3 – 83 to 233 dwellings per year; SS4 – 86 to 235 dwellings per year; SS5 – 0 to 69 dwellings per year; SS6 and SS7 would enable Runnymede to fully meet the OAN within the Borough.

All of the options would result in development in the Green Belt and this is inevitable given the nature of the Green Belt in Runnymede and the demand for housing. SS3 and SS4 would focus development in urban areas, previously developed sites in the Green Belt and RLPs. The Council’s Strategic Review of the Green Belt (2014) found that RLPs either do not meet or only weakly meet Green Belt purposes as set out in the NPPF. Therefore, development on these sites and the previously developed sites in the Green Belt (dependent on how it is implemented) should be more acceptable than other sites within the Green Belt. However, in recognition that this still represents development in open countryside (and there is likely to be effects on Green Belt and landscape) these approaches have been scored as minor negative. The assessment against SA objective 1 is also relevant here – any unmet need that needs to be accommodated in neighbouring authorities is also likely to be constrained by Green Belt but the effect of this is uncertain. Once it is clearer where any unmet need is likely to be located further work should be undertaken to understand its sustainability implications working in conjunction with neighbouring authorities. SS5, SS6 and SS7 would also release increasing amounts of Green Belt land in uncertain locations. Development on these additional parcels of land

4.3 Thorpe village boundary options

4.3.1 What has been assessed?

The alternative approaches have been assessed against a small number of the SA objectives only. The generic approaches to the options are unlikely to affect the other SA objectives so these have been screened out of the assessment. Please see Appendix 1 for an explanation of the content of each alternative. This assessment takes a particularly precautionary approach in that it considers constraints and opportunities within the area of Thorpe and assesses what the impacts of defining a boundary between the village and the Green Belt could potentially be if it led to development. However, please note that an option to include an area to be within the village boundary does not mean that it has been allocated for development and an assumption cannot be made that development will occur on these areas in the foreseeable future. The spatial strategy included several options to exclude the village of Thorpe from the Green Belt, which if taken forward, would see Thorpe treated as part of the urban area for planning purposes. This means that the village will cease to be part of the Green Belt and will be considered as urban area mean-ing that development would be more acceptable. This assessment considers the effects for a number of options where a detailed village boundary could be defined, whereas the effect of excluding the village from the Green Belt has been assessed in the spatial strategy options. Please also note that before a site is allocated for development or planning permission is granted, an assessment will be made of the likely environmental effects and appropriate mitigation put in place.

4.6.1 What has been assessed?

The approach to the assessment of the alternative approaches is set out below:

• BE1 - BE3 and BE5 - BE8 - The approaches have been assessed against a small number of the SA objectives only. The generic approaches to the options are unlikely to affect the other SA objectives so these have been screened out of the assessment. In addition, any site specific issues which would require mitigation have been addressed in the assessment of the sites (see Appendix 2);

• BE4 – It is felt that because BE4/01 does not set out what a general policy on the environment could contain, it’s not possible to make a meaningful assessment at this stage. An assessment of the Local Plan policies will be made as part of the assessment of the Draft Plan.

The generic approaches to the options are unlikely to affect the other SA objectives so these have been screened out of the assessment. In addition, any site specific issues which would require mitigation have been addressed in the assessment of the sites (see Appendix 2).

The approach to the assessment of the alternative approaches is set out below:

In addition, any site specific issues which would require mitigation have been addressed in the assessment of the sites (see Appendix 2). Please note that the alternative approaches for H1 to H9 are effectively the same, as follows. Therefore, these have been assessed as one issue:

The area covered by the River Thames scheme is the largest area of undefended floodplain in England. F1/A02 is uncertain because the exact nature of the “other measures” is unclear. The River Thames scheme has been subject to a SEA and this highlights the significant effects of the pro-posed scheme. F1/B01 would be a more comprehensive solution to solving flooding issues than relying on flood alleviation schemes. In addition flood alleviation schemes are a long term so-lution and may leave properties vulnerable in the meantime.

ANNEX 1 SCREENING OF THE ALTERNATIVE ISSUES AND OPTIONS

SUSTAINABILITY APPRAISAL OF THE ISSUES AND OPTIONS Runnymede

The information presented by the Council in the Issues, Options and Preferred Approaches consultation document is more than just potential development sites. It is a mix of options, potential approaches and sites. It is not possible or useful to assess the effects of these potential approaches against every element of the SA frame-work, either because they will have effects on only some of the sustainability topics or because alternatives have not been suggested (and the purpose of this stage of the assessment is to help the council determine between alternatives). Therefore each potential approach has been assessed slightly differently (against different SA objectives) and some of them have not been assessed. However, please note that all policies developed as part of the Draft Plan will be assessed as part of the next stage of the SA. To determine whether the approaches are likely to have an effect on the SA objectives (and therefore whether an assessment is needed), a screening table has been used. This is shown below:
