Application for costs 2. In advance of the Inquiry, I received an application for costs from Exigo Project Solutions against Rother District Council. This application is the subject of a separate Decision. Procedural Matters 3. I have considered the issue as to whether the appeal required a Screening Opinion under Regulation 5(1) of the Town and Country Planning (Environmental Impact Assessment) Regulations 2017. The Secretary of State reviewed the appeal papers and issued a Screening Decision that an EIA is not required. I am satisfied with his decision in respect of this matter. 4. In advance of the Inquiry I received notification on 4thJune that the Council had withdrawn its second reason for refusal (R4R). 5. During the Inquiry there was a brief discussion on the information on which I should base my decision.

The application has been submitted in outline with all matters reserved apart from access. I am treating the suggested schematic layout included within submitted plan, 1743-SK-P-204 D, as for illustrative purposes only. 7. The main parties in the Statement of Common Ground agree that reference in the decision letter to Policy EN6(ix) was a drafting error and should have referred to EN6(iv). 8. During the presentation of the Council’s evidence ‘in chief’, regarding the ‘planning balance’ various corrections were made to policy references. 9. At various points during this decision, I refer to SPINDAG, a local residents group who are opposed to the appeal scheme and have provided a body of evidence in support of its case. 10. The appeal was submitted with a completed Unilateral Undertaking which includes the provision of affordable housing, a detailed Sustainable Drainage System (SuDS) and its management arrangements, highway works, contributions to bus services and travel plan monitoring. I make further reference to this Undertaking in the decision. 11.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision In advance of the decision being issued I sought the views of parties on the revised National Planning Policy Framework 2021 (the Framework) which was issued after the Inquiry. Only SPINDAG provided comments which I have included in the decision below. Policy 12. The Councils adopted Local Plan is in 2 parts, a Core Strategy 2014 and the Development and Site Allocations (DaSA) Local Plan 2019. Policy BEX9 of the DaSA allocates the appeal site for 160 dwellings subject to 13 criteria. These includes a requirement for access from Spindlewood Drive and Barnhorn Road; these are included in this appeal scheme. 13. Of note is the criteria which requires, that in accordance with DaSA Policy DEN 5, ’Sustainable Drainage’, 2 forms of SuDS are incorporated and that an Appropriate Assessment under the Habitat Regulations can demonstrate that beyond scientific doubt these can be delivered on the site without harming the integrity of the Pevensey Levels Special Area of Conservation (SAC) and Ramsar. A schematic plan identifying key features of the allocation was included with the policy. Main Issues 14.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Appeal Decision APP/U1430/W/20/3270665 15. In 2018, the Court of Justice of the European Union ruled that the decision maker, when considering the effect that a proposal may have on a European Site, must consider mitigation within the framework of an Appropriate Assessment (AA) rather than at the screening stage1 where the potential for likely significant effects is considered. 16. As a project progresses from inception through to implementation a series of decisions are required to be considered against the Habitats Regulations, (the Regulations) and where necessary an Appropriate Assessment (AA) has to be taken for each decision. Three AAs have been completed as this project has progressed. The first was part of the original submission to the Examination in Public of the Local Plan DaSA, the second by the Examining Inspector and the third by the Council in advance of the determination of the application. 17. Each of these concluded that the required mitigation could be properly secured and that the proposals would not have an adverse effect on the identified SAC and Ramsar either alone or in combination with other projects. The responsibility of completing a further AA now falls to me as part of this appeal. 18.

Page 3 · Chunk 9 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The Habitats Regulations2 (the Regulations) require that if likely significant effects on a European site cannot be excluded, permission may only be granted after having ascertained that it will not affect the integrity of the site either alone or in combination with other plans or projects. In completing an AA there should be no gaps in the considerations which inform the decision. If adverse effects on the integrity of the protected site cannot be excluded on the basis of objective scientific evidence then it must be assumed that they will occur. However, this is an outline application and my assessment should be proportionate to the amount of evidence before me. 19. The appeal site lies within 100m of, and within the hydrological catchment of the Pevensey Levels (the Levels), designated as a Special Area of Conservation (SAC), Ramsar, and a Site of Special Scientific Interest (SSSI). The Levels comprise almost 3,600ha of low lying grazing meadows wetland, interspersed by a complex system of ditches which contain a wide variety of form and species composition and support important communities of wetland flora and fauna.

Page 3 · Chunk 10 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The Levels are identified as a Ramsar site for the outstanding assemblage of wetland plants and invertebrates. The site supports around 68% of the vascular plant species in Great Britain which can be described as aquatic. 20. Whilst the Levels are an important habitat for wetland plants and invertebrates including British Red Data Book species, Lapwing and butterflies, its qualifying feature identified in the SAC includes habitat for the Lesser Whirlpool Ramshorn Snail (Anisus vorticulus) (the snail). The JNCC3 describes this species as a small, aquatic snail with a flattened spiral shell no more than 5mm in diameter. 21. Critical to the ecology of the Levels is the management of a sufficient supply of unpolluted freshwater. It is the quantity and quality of the run-off from the proposed development and its potential effects on the ecology and in particular on the qualifying features of the Levels which is at the heart of this main issue. 22. The proposed scheme includes a sustainable drainage system (SuDS).

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Appeal Decision APP/U1430/W/20/3270665 scheme is taken by a series of swales to a main swale running through the site, which flows, via a wetland forebay to a drainage basin which in turn would discharge via a controlled flow to the Cole Stream, a natural water course serving the Levels, which runs along the eastern edge of the appeal site. There are a series of filter strips throughout the system to aid pollution control. 23. The Council’s assertion that the appellant has not considered a worst case scenario primarily rests on several variables including rainfall methodology, the extent of impermeable area and long term storage. Its case also refers to other factors such as discharge volume, groundwater levels, tidal climate change, hydraulic calculations and drainage planning4. 24. Each of these areas are linked and rely on detailed calculations. For this reason, I have made an overall assessment of these variables before concluding whether any adverse impacts would arise for the qualifying features of the SAC, Ramsar and SSSI. 25.

Page 4 · Chunk 14 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Underpinning the appellant’s case is that an appropriate drainage system could be engineered to ensure that the level of run-off could be managed to ensure that discharge to the Cole Stream would not have an adverse impact on the ecology of the Levels. 26. Assessment of the ‘worst case’ is beyond the requirements of HR, although both parties accept that this is a rational approach given the potential impacts on the Levels. Rainfall methodology 27. It is accepted by both main parties that the reference included in the Council’s reason for refusal to ‘rainfall assumptions’ actually refers to rainfall methodologies. 28. There are 2 commonly accepted rainfall methodologies5 the FSR and FEH. The FEH13 is a refinement of FEH99. None of these is preferred by statute. They are required to inform a consistent and reasonable estimate for the determination of water storage decisions6. Despite the relatively small size of the appeal site, I am satisfied that the appellant’s modelling is appropriate for assessing the worst case scenario. 29. Initially, the appellant proposed the FSR method because it generates higher rainfall than FEH13.

Page 4 · Chunk 15 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision However, in response to consultation, the FEH13 was selected on the basis of the need for a fixed discharge rate; this in turn requires higher storage volumes which would determine the size of the drainage basin. For example, in December 2018 the largest volumes of storage required was estimated, by the appellant to be around 2,955.8m3 and 3229.6m3 respectively for the FSR and FEH methodologies respectively7. These account for the discharge volume suggested by the Council. 30.

For this return period, these studies suggest a storage volume requirement of 1,623m3 for the FEH and 1,513m3 for the FSR methodology although the appellant’s report of August 2020 report identifies a capacity of 1,965m3, 10. 31. Other sensitivity testing was carried out against fixed discharge rates limited to Qbar rates above 1:2 year event which demonstrates that FEH represents the worst case scenario when applied to the drainage strategy11. Crucially in this case, the capacity of the proposed drainage basin, even when located at surface level would be sufficient to allow for the return period of 100year+40%. 32. Further testing was completed in respect of the comparison between the impermeable area of between 2.6-3.2ha with the worst case (FEH) methodology and a Qbar discharge rate for the 100year+ 40%. Even for this extreme event this demonstrates that the basin would have sufficient capacity. 33.

Page 5 · Chunk 17 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The Council’s objection to the proposed scheme, that it hasn’t been tested against a consistent set of parameters, is overstated given the extent of sensitivity testing included in the appellant’s evidence. The Council’s witness agreed that the storage capacity required for the worst case scenario could be engineered and delivered on the site. For these reasons, I consider that the appropriate methodology has been tested to demonstrate the worst case scenario. 34. Whilst I acknowledge the concerns of SPINDAG on this point12, I am satisfied that the extent of modelling of both methodologies during the 4 years in which the scheme has emerged through negotiations between the appellant, the Council and statutory consultees, demonstrates that the implications of each of these methodologies has been fully considered. Impermeable area 35. The proposed development would result in an increase in the rate of rainfall run-off compared to the rate if it was retained as greenfield. The Council agree with the appellant’s methodology for assessing the extent of the impermeable area which results from the extent of the urban areas within the scheme13, although there is disagreement on the allowance for urban creep14. 36.

Page 5 · Chunk 18 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The difference has emerged from the appellant’s re-calculation of the extent of the urban area, which has changed as successive iterations of modelling have been developed. The appellant now assesses the urban area within the appeal scheme to be around 2.6ha. It would seem that the change which occurred since the Council’s refusal was to account for the re-designed road and reflects detailed topographical studies and groundwater surveys. 9 An estimate of the likelihood of a particular event occurring.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Appeal Decision APP/U1430/W/20/3270665 37. Of critical importance in respect of this matter, is not the exact area of impermeable land but whether within sufficient tolerances the run-off could be adequately accommodated within the swales, forebay, main wetland and drainage pond. Whilst this matter is inextricably linked to the discharge rate from the drainage basin to the Cole Stream, which I address later, I am satisfied that the appellant’s sensitivity analysis15 has modelled the extent of impermeable area ranging from 2.6-3.2 ha with a worst case scenario demonstrated by the application of the FEH rainfall method. The size of basin is within appropriate tolerances. 38. The comparable figures demonstrate that even with an impermeable area extending to 3.2ha, with FEH methodology and with discharge set at Qbar16 there would be sufficient capacity to avoid overtopping. This again provides assurance that the worst case scenario has been sufficiently addressed. 39. The appellant has identified that the existing methodology and extent of run-off does not account for other means of water management which would intercept rainwater before it reaches the drainage basin.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision These could include measures such as green roofs and permeable paving. It will only be at Reserved Matters Stage that these measures can be fully addressed. Impact of groundwater levels on drainage design 40. The site slopes from around 19m AOD17 in its north west corner down to around 4m AOD by the Cole Stream. Groundwater monitoring indicates the highest groundwater level is in the south eastern corner of the site at around 0.62m bgl18. To ensure that the land is of sufficient height to allow gravity flow through swales from this area and to ensure that the drainage basin would have sufficient ‘freeboard’, the proposal involves raising the height of the swales and drainage basin by between 0.5-1.619m. This would ensure that the proposed drainage basin would be sufficiently clear of groundwater. 41. The appellant has allowed for a potential increase in the capacity of the basin by lowering it into the ground. To protect ground water the scheme could include a geosynthetic waterproof membrane and sacrificial membrane.

Page 6 · Chunk 21 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision I do not consider that, if such an approach is used, the depth of the proposed lining would significantly impact on the natural flow of groundwater beyond the limits of the drainage basin, if this was indeed required. 42. The shallow profile of the pond would not to my mind require some counter weight as ballast for stability as suggested by SPINDAG20 and there would be sufficient tolerances between the bottom of the basin and the level of groundwater level to accommodate this. 43. Consequently, I am satisfied that the proposed basin could be located on site with an adequate capacity which would not result in interference with groundwater.

The Council has raised other matters in respect of climate change and the hydraulic calculations but made it clear that these matters were not being advanced as critical issues in themselves. 45. In respect of tidal levels, the Council acknowledge that the appellant’s modelling of a 1:200 year tidal breach locking the outfall from the wetland, is considered reasonable21. The Environment Agency has not objected to the appellant’s conclusions in respect of this matter. 46. Regarding hydraulic calculations, I am satisfied that despite the discrepancy included in the appellant’s earlier evidence on this point22 the proposed height of the invert level of the outfall from the attenuation pond would be at 4.8m, allowing for an adequate discharge structure and outfall to the Cole Stream. Discharge rate 47. The Council’s case is predicated on several points relating to the shortcomings in the proposed SuDS resulting from a regulated discharge rate from the drainage pond to the Cole Stream and concerns over the limitation of filtration which in turn could adversely impact on water quality and the ecology of the Levels. 48.

Page 7 · Chunk 23 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision As part of the application for planning permission, the proposal included a discharge at the Qbar rate, but following the LLFA’s comments this was revisited to include a variable rate. This latter could allow a rate of run-off close to and not exceeding the natural ‘greenfield’ rate which is a requirement of Policy DEN5. 49. Whilst the Council acknowledge23 this matter could be appropriately dealt with at reserved matters stage, the critical issue for the purposes of the AA is to assess the potential impact of the rate of discharge on the ecology of the Levels. 50. Of the 6 pathways identified by the appellant24 in how surface water and /or groundwater pollution could impact on the Levels, the Council takes exception with two which are interlinked. These include the impact of an increase in impervious surfaces that prevents rainfall percolating into the soil and how this could ultimately alter the wetland hydrology, and secondly, on how an increase or decrease in water flow into wetlands may alter species composition and decrease pollutant removal efficiency with potential effects on the food web. 51.

Page 7 · Chunk 24 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision In respect of the first, the shallow depth of the proposed swales is unlikely to result in an impermeable barrier located to a depth which would significantly affect run-off rates across the wider site. Given the size of the impermeable areas, the effects of this for the natural rate of percolation, and the peak greenfield run-off rate (GRR25), across the whole site, would be negligible. 52. The appellant acknowledge that the SuDS will smooth out the water flow into the Cole Stream and would introduce a lower flow rate over a longer period of time resulting in a reduction in the dynamism of the wetland system, which can 21 Rebuttal Proof of Mr Cafferkey para 5.1 22 Rebuttal of Mr Maiden-Brooks at para 3.17 23 Closings paragraph 33 24 PoE Mr A Baxter 25 Greenfield Runoff Rate – the peak rate of run-off for a specific return period due to rainfall landing on a given area before development https://www.gov.uk/planning-inspectorate 7

This could potentially impact on the qualifying feature of the SAC, the Lesser Whirlpool Ramshorn Snail, which requires winter flooding, amongst other factors, to disperse populations across the Levels enabling colonisation to avoid interbreeding and species survival. 53. The Council advises that through the application of the precautionary principle the appellant’s failure to consider the impacts of a decrease in the rate of water entering the Cole Stream on the snail is an omission or lacuna, and for this reason, this local significant effect cannot be screened out. 54. Research quoted by the appellant identifies that the snail is a robust species which can tolerate a variety of conditions and has the ability to reproduce and establish large populations within a year26. 55. Whilst there is limited research on the life of the snail it is clear that other vectors can support population dispersal. Furthermore, the fact that statutory agencies including the Environment Agency and Natural England have not objected to the scheme with either Qbar or variable rate of discharge from the drainage basin to the Cole Stream is instructive in this regard. 56.

Page 8 · Chunk 26 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision It is understood that for the Clavering Walk27 appeal, the variable discharge rate was set at 65% of the GRR; this was accepted by the statutory bodies. 57. Furthermore, the proposed SuDS includes 3 levels of pollution treatment designed to ensure that discharge from the drainage basin would be unpolluted water. 58. The Council state that the risk of a catastrophic failure of the SuDS has not been fully addressed and that this was a gap which had to be addressed in line with the Regulations. However, I consider that the degree of safeguards built into the appellant's SuDS design has sought to ‘design out’ this possibility. The fact that the Council has not refused the application with reference to Policy DEN5 reflects that they did not consider this to be a possibility. 59. Finally, the Council acknowledged that whilst many of these factors would individually have limited impacts28 it is their combination which is critical. Having considered each factor, I do not consider this to be the case and the appellants sensitivity analysis demonstrates that collectively the Council’s criticisms are unfounded. In combination with other projects 60.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision I am required, by the Regulations, to consider the locally significant effects in combination with other plans or projects. Although there are several site allocations included in the DaSA which would drain into the Levels, their locally significant effects were screened out during Examination of the Local Plan. No applications have as yet been received for these sites. 61. Recent appeal decisions allowing development at unallocated sites at Ashridge Court29 and Claverings Walk both conclude that alone and in combination with other projects they would not result in locally significant effects on the qualifying features of the Levels.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Appeal Decision APP/U1430/W/20/3270665 applied to this appeal scheme, I am satisfied that there would be no in combination adverse impacts on the qualifying features of the SAC and Ramsar. Concluding comments on this main issue 62. I am aware that the application of the Habitats Regulations during the life of the site allocation through to the inception of the outline appeal scheme requires a series of separate decisions. The fact that a succeeding stage in this process, for example the submission of reserved matters would follow, still requires me, as competent authority, to be satisfied beyond all reasonable scientific doubt as to the effects of the scheme on the Levels. This should be achieved through the application of the ‘precautionary principle’ to unequivocally demonstrate why the protected habitat and species would not be adversely affected. 63. The proposed scheme is submitted in outline with only details of means of access to be considered at this stage. Whilst this has required some generalised assumptions on the amount of developed area, the converse is true of the wealth of detail on the surface water drainage strategy. A proportionate approach is required to this matter. 64.

Page 9 · Chunk 29 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The appellant’s proposed scheme demonstrates that a solution can be engineered within a range of different parameters. The list of conditions included in this decision reflects the extent of detail which is still required to be considered and would provide further safeguards for the protection of the Levels before the site would benefit from a full planning permission. 65. There are sufficient safeguards built into the appeal scheme which can overcome the concerns of the Council and SPINDAG30. The drainage solution can be engineered to ensure that the worst case scenario can be managed. The position of the surface water swale limits the extent of excavation, which could compromise the groundwater levels and the extent of run-off. Furthermore, the appellant’s suggestion of the inclusion within the scheme, of a geosynthetic membrane and a sacrificial lining could provide protection for groundwater if a slightly deeper swale was engineered. 66.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision I am satisfied that the additional measures referred to by the appellant, which have not been factored into this scheme, could provide additional forms of interception, reducing the rate of run-off and allowing for further enhancements to water quality before it enters the swales, forebay and drainage pond; albeit these need to be secured as part of the reserved matters. I am further satisfied that sufficient modelling and assessment has been completed to ensure that tidal effects would not impact on the drainage strategy. 67. Although the requirements of the Habitats Regulations sit above local policy considerations, the Council has referred to specific policies in its first R4R relevant to this matter. Policies EN5(ii), (viii) and (ix) require the protection of internationally, national and locally protected sites of importance for biodiversity and for new development to avoid adverse impacts on these areas. Policy EN6 seeks partnership working to deliver effective flood risk management. 30 Statement of Mr Lawson https://www.gov.uk/planning-inspectorate 9

On the basis of the submitted surface water drainage strategy, I conclude that the proposed scheme, either alone or in combination, would not adversely impact on the qualifying features of the Pevensey Levels SAC, Ramsar and SSSI. The appeal scheme would not conflict with Policies EN5, EN6 and SRM2 of the Core Strategy 2014. Furthermore, the inclusion of a SuDS is supported by Policies DEN5 and BEX9 of the DaSA 2019. Landscape impacts 69. Landscape is a reserved matter. In respect of this main issue, the difference between the parties is only relevant insofar as it relates to the ground levelling required for the drainage basin and the development platform at the south western edge of the site. These works are required to enable gravity flow drainage through the swale from both the proposed road and development platform lying on the site’s southern edge to create the drainage basin with sufficient capacity to accommodate the anticipated run-off from the development. 70.

Page 10 · Chunk 32 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The character of the site’s topography means that although it lies within the National Character Area profile 122 High Weald, and at Regional level within the Pevensey Levels LCA 2531 as set out in the East Sussex LCA 2008, the site reflects few of the characteristics which define these areas. 71. The submitted plans and cross sections are illustrative and provide only general guidance as to how the final scheme could appear. The submitted scheme indicates ground raising of around 0.5m to a maximum height of around 1.7m. on the south east edge of the site. This is below the height estimated by SPINDAG32. 72. The site comprises grazing pasture set within 5 small fields with boundaries defined by thick tree belts including a tree belt along the site’s eastern edge by the Cole Stream. 73. Due to the topography of surrounding areas, the treed boundary along the Cole Stream and existing field pattern only parts of the site are visible from the rear of properties in Barnhorn Road, Mulberry Close and Spindlewood Drive. The wooded edge along the Cole Stream allows only intermittent views from Old Harrier Close and Hazelwood Close.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The site can be seen from those caravans within the neighbouring site which are located close to its common boundary. The presence of this development compromises the site’s rural character and confirms the Council’s Landscape Assessment of the site as having a ‘strong urban fringe character’ with a low sensitivity to change. 74. Two public footpaths would act as receptor points allowing views both into and across the site. These run in broadly north-south and east-west directions at the southern end of the site. 75. The field within which the drainage basin would sit lies between 4-7m AOD. At its maximum the ground raising required to achieve the appropriate height to contain the water including a ‘freeboard’33 would be around 1.634m on the southern edge of the pond; its highest point due to the fall in the topography to 31 Landscape Character Area 32 Statement of Mr Lawson 33 A term used to describe the difference in height between the design water level and the top of a structure, provided as a precautionary safety measure. 34 Appx 11 Technical Note -para 3.9 https://www.gov.uk/planning-inspectorate 10

With a gradient of 1:3, the bank to the pond could, through appropriate landscaping, appear as a natural feature. 76. The drainage basin would be seen clearly from both footpaths but only on immediate arrival in the southern field where it will be located. Long distance views would not be readily afforded due to the well treed field boundaries. For the same reason, the creation of the southern development platform would not be discernible from either footpath given the extensive tree belts along the field boundaries. 77. The Council's R4R refer to Policies EN1(iii), (v) and (vii). These focus on the protection and enhancement of nationally designated and locally distinctive landscapes and features and ENV(v) identifies the importance of open landscape between clearly defined settlements and retention of tranquil and remote areas. 78. The reference to the site allocation within Policy BEX9 of the DaSA, effectively includes the site within the settlement boundary.

Page 11 · Chunk 35 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The site is not remote given the surrounding housing and whilst it lies within the NCA 122 and LCA 25, the site’s self containment means that the ground raising would not adversely impact on these designated areas. The existing thick tree belts along the Cole Stream would protect views of the proposed development from the south eastern side of the site and the submission of reserved matters for Landscaping would allow an opportunity for a scheme to achieve the same for the site’s shared boundaries with Spindlewood Drive, Mulberry Close and Barnhorn Road. 79. Whilst the application of Policy EN1(viii) is understood, the indicative scheme could retain the field pattern and boundary hedging could be retained broadly as existing. The form of development suggested in plan 1743-SK-P-204 D is similar to the schematic plan which accompanies Policy BEX9 and views would be largely contained within the site. 80. For the above reasons, I conclude that the form and extent of changes proposed to the site arising from the proposed attenuation pond, road and development platforms would not conflict with Policy EN1. Furthermore, there is nothing in the submitted scheme to suggest a conflict with Policy BEX9 of the DaSA.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Interested parties 81. SPINDAG made representations on several matters during the Inquiry which I address below. Domestic pets 82. Objections to the proposed development on the potential recreation impacts on the Levels are not fully evidenced. Whilst occupants of the proposed scheme are likely to have direct access to the Levels via the existing footpath network, the actual increase in visitor numbers is unlikely to be so great as to undermine its qualifying features. It is instructive to note that Natural England35do not consider that recreational activities would have any adverse impacts. For this reason, I consider that the recreational impacts would not be so great as to adversely impact on the qualifying features of the SAC and Ramsar. 35 ID.6 https://www.gov.uk/planning-inspectorate 11

On a related point additional concerns were expressed regarding flea treatment for dogs, which use a toxic insecticide. SPINDAG allege that this insecticide could enter the ecology of the Levels through surface water runoff after dog washing and cite a recent research paper36 which identifies the potential for such adverse impacts. This is just one recent research paper and it is unclear the extent of peer review. This matter has been raised directly with Natural England who do not consider that this is a matter of concern given the numbers of dogs which could live on the proposed development. 84. Whilst the proposed development would likely increase the local population of cats there is no evidence to suggest whether their ‘wanderings’ would extend for over 100m into the Levels to prey on dormice, which are a qualifying feature of the Ramsar. 85. SPINDAG also refer to potential harm to the Fen Raft spider, a Red Data Book species and a qualifying feature of the Ramsar. However, it is unclear how an increase in footfall from proposed development could adversely impact on the local colony. 86.

Page 12 · Chunk 38 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Although there is always potential for some conflict between visitors to the countryside and the welfare of cattle and sheep, there is no evidence to suggest that the new residents of the proposed scheme would not adhere to the Countryside Code in the same way that SPINDAG states its members do. Cooden Moat Scheduled Monument (SM) 87. Cooden Moat SM, lies at the southern edge of the appeal site and is entirely covered by woodland which extends into the woodland belt along the Cole Stream. The SM is laced with footpaths and appears entirely unmanaged. This has the effect of limiting a full appreciation of its history. 88. The proposed new development platform within the appeal scheme, being set over 100m from the SM would have limited impact on its setting. The form of the drainage basin, designed as a natural form, would not adversely impact on the SM. 89. Whilst the appeal scheme would very likely result in an increase in the recreational use of the footpath network which runs through the SM, the resultant harm would be marginal, even allowing for the additional impacts which could arise from the additional residents from the Claverings Walk scheme.

Likewise, whilst SPINDAG identified the continued decline of habitats and species these matters would have been considered as part of the Examination into the proposed policy. 92. Other concerns raised by interested parties relate to the distance of the proposed scheme from existing services and facilities and the likely pressures arising on schools caused by an increase in population from the development. The appeal scheme accords with the parameters of Policy BEX9 and, as part of the plan led system, these matters would have been considered at the Examination stage. Evidence was presented by the appellant that schools have plans to create additional school places. 93. The site lies within 10-15mins walk of the centre of Little Common which has a range of shop and services. The No.99 bus has regular services along Barnhorn Road to the centre. It is instructive to note that the Council withdrew its second reason for refusal, which related to this matter. 94.

Page 13 · Chunk 41 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision SPINDAG raised additional concerns in respect of the width of the proposed Barnhorn Road access and the impact of additional right turning movements on Barnhorn Road, the A259. However, the Highway Authority has not objected to the proposed scheme and this is a matter which would have been considered as part of the Examination of the Local Plan in advance of the site allocation being confirmed. The Highway Authority has not objected to the additional traffic movements on the capacity of the A259 which would arise from the appeal scheme. I am satisfied that the detailed drawings included in the appeal scheme for each road access can be adequately accommodated. Conditions which form part of this decision require further details of these access points. 95. Furthermore, whilst SPINDAG intimate that that the proposed development could become a rat run diverting traffic from Barnhorn Road through residential areas along Maple Walk, the detail of the proposed road has not been agreed. 96. Other comments relate to the proximity of the proposed development to existing residential properties. However, the proposed scheme is for around 160 dwellings and the detail of the layout has not yet been finalised.

Revised Framework 2021 97. SPINDAG refer to several parts of the Framework which I address below. 98. References to the importance of local community views in the planning process have to be balanced in respect of the appeal site with the Council’s decision to allocate this site for housing. I understand that SPINDAG engaged fully in the plan making process in advance of the allocation being confirmed. 99. Whilst sites within the District may have the benefit of planning permission but are not being developed the critical test is whether the Council has a 5 year housing land supply. The Council acknowledges that this was 2.87 years supply as at April 202037. There is a need for additional housing to meet the requirements of the Council. 37 Revised SoCG June 2021 https://www.gov.uk/planning-inspectorate 13

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision Appeal Decision APP/U1430/W/20/3270665 100. This is an outline application and the main parties agree that more detailed information has been provided for this scheme, at this stage than for the two other appeals referred to earlier in this decision. The conditions included in this decision are designed to provide further safeguards as more detail is submitted in response to the Reserved Matters. 101. The appellant owns the land within which the drainage basin will sit. They have sufficient control of the land to enable maintenance. The policy requirement included in the Framework can be addressed through the more detailed scheme. A series of conditions included in this decision will support this aim. Planning Obligations 102. The appeal was accompanied by a completed Unilateral Undertaking, dated 9 July 2021. This includes a range of measures including the provision of affordable housing, green infrastructure, management companies for the housing and landscaping, a new bus stop, requirements for a travel and construction travel plan and various highway works to enable the delivery of the proposed vehicular access points and finally bus services. 103.

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The Undertaking was accompanied by a Community Infrastructure Levy compliance statement. This highlights how each obligation included in the Undertaking is supported by adopted policy. 104. Overall, I am satisfied that the obligations included in the undertaking are related to the requirements of development plan policies and are necessary, directly related and fairly and reasonably related in scale and kind to the proposed scheme in line with paragraphs 57 of the Framework 2021. Heritage balance 105. The extent of harm on Cooden Moat SM arising directly from the appeal scheme would be less than substantial. Although I must give considerable importance and weight to even such limited harm, in the wider context of the appeal scheme this has to be set against the considerable public benefits which would arise from the delivery of housing, on what is an allocated site Planning Balance 106. At the heart of this decision is whether the proposed surface water drainage strategy has been assessed against a worst case scenario as suggested by rainfall methodologies and other factors to prevent adverse impacts on the qualifying features of Pevensey Levels SAC, Ramsar and SSSI.

The scheme includes appropriate levels of pollution treatment to minimise the risk of pollutants entering the Levels and adversely impacting on the qualifying features of both the SAC and Ramsar. 109. At this stage, given the level of detail included with the outline scheme, I am satisfied beyond all reasonable scientific doubt that based upon the currently available information the proposed surface water drainage strategy incorporating the SuDS would not adversely impact on the qualifying features of the SAC, Ramsar and SSSI. The range of conditions, I have imposed on this decision are designed to set the parameters for the surface water drainage strategy for Reserved Matters. They are proportionate to the level of detail required for the scheme at that stage. This approach adheres to Regulation 70(3) of the Habitats Regulations. 110.

Page 15 · Chunk 48 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision With regard to the landscape impacts of the ground levelling proposed for part of the southern development platform and the drainage basin, I am satisfied that the existing topography would allow the creation of the basin in a way, as suggested which would not detract from the contained field parcel within which it would sit. In respect of the development platform, the nature of the existing field pattern would be retained and for this reason it would not be harmful when considered from receptor points within the site or from beyond the site and particularly from the east due to the broad landscape boundary along the Cole Stream. 111. The Council does not have a policy compliant housing land supply. This has declined38 since 2020 and currently stands at 2.87 years. In these circumstances Paragraph 11d (ii), and Footnote 8 of the Framework (2021) requires that the tilted balance is engaged, as the policies for determining this application are considered out of date. 112. The most important policies of the development plan, directly relevant to the issues raised in this appeal are EN1, EN5, EN6, SRM2, DEN5 and BEX9.

Page 15 · Chunk 49 Appeal Decision

Land off Spindlewood Drive, Land to the west of Spindlewood Drive, BEXHILL, TN39 4QU — Rother District Council — Appeal Decision The environment policies EN1, EN5 and EN6 identify closely with Chapter 14 of the Framework which requires that the risks involved with development proposals in locations which are vulnerable to flooding should be managed through suitable adaptation measures for its lifetime. 113. Policies SRM2 and DEN5 require the effective management of water resources through the promotion of SuDS to control the quantity and rate of run-off to improve water quality within the hydrological catchment of the Pevensey Levels. These policies accord closely with Paragraph 180 of the Framework. Finally, Policy BEX9 being an adopted housing allocation is consistent with the plan led approach advocated by the Framework. 114. Given the high degree of consistency between the Council’s adopted policies and the Framework when read as a whole, I give substantial weight to the application of these policies to the appeal scheme. 115. Given the constraints imposed on new development by the international and national designations across the District, the appeal scheme would deliver a housing allocation.

The appeal scheme would result in economic benefits in the form of construction jobs and through the increased spend by new residents in local services in Little Common. Social benefits would arise from the amount of affordable housing and environmental benefits in the form of a new housing in a location which enables access to shops and services by a choice of transport modes. 116. When the proposal is viewed both in relation to the Framework as a whole and the adopted Local Plan the result is the same. There is no policy argument against the appeal scheme. Material circumstances do not indicate that a decision should be taken other than in accordance with adopted policy. Conditions 117. I have reviewed the list of conditions included in the Statement of Common Ground and had regard to the discussions during the Inquiry in respect of conditions on levels and the surface water drainage strategy. 118.

Although the entrance gates to Barnhorne Manor Farm have little architectural or historic significance I recognises that they have local interest and for this reason, I have imposed a condition requiring their dismantling, storage and consideration for re use in the detailed scheme in the future. 120. In the interests of highway safety, a condition is imposed requiring full details of the sight lines to the proposed access from Spindlewood Drive and its completion in advance of first occupation of dwellings on the site. For the same reasons, conditions are required of details of parking spaces and turning areas together with the completion of footways and roads. 121.
